Description

  The present invention relates to a gaming machine such as a pachislot machine or a pachinko machine.

  Some conventional gaming machines use a projector instead of a liquid crystal display device that displays video for games (see Patent Documents 1 and 2). In such a gaming machine, an image is projected from a projector onto a projection surface such as a screen.

JP-A-6-35066 JP 2009-240459 A

  However, in the above conventional gaming machine, the projection plane is always at a certain distance from the projector, the position of the projection plane does not change relative to the projector, and the optical means is based on uniform setting information. Therefore, it is difficult to enhance video visual effects such as three-dimensional visual effects and dynamic visual effects.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a gaming machine capable of promptly projecting a high-quality image with a high visual effect on the projection surface after displacement. To do.

  In order to achieve the above object, the present invention provides the following gaming machines.

A gaming machine according to one aspect of the present invention,
A projection device (for example, projector device B2 etc.) that projects an image by irradiation light;
A plurality of projection surfaces (for example, the reflection surfaces of the reflection portions D1 to D4, the projection surface E11a, the projection surface F1a, etc.) capable of displaying the image projected by the projection device;
A projection surface drive mechanism (for example, front screen drive mechanism E2, reel) that displaces at least one of the plurality of projection surfaces (for example, projection surface E11a, projection surface F1a, etc.) relative to the projection device. Screen drive mechanism F2 etc.),
Control means for controlling the operation of the projection plane drive mechanism and controlling the projection apparatus (for example, a sub-control board SS),
The projector is
Optical means for projecting an image (e.g., projection lens 210);
Optical control means (for example, focus mechanism 242, control LSI 230 of projector control board B23, etc.) having a focus mechanism for controlling the optical means,
The optical control unit includes a focus mechanism control unit (for example, a lead screw 242B of the focus mechanism 242 and a control LSI 230) that controls the focus mechanism.
The control means performs a focus change time calculation means (for example, a focus change request process) that calculates a focus change time based on a required operation time of the projection plane drive mechanism and a time required for changing the focus position of the focus mechanism. Sub CPU 400 etc.)
The control means instructs the optical control means (for example, a sub CPU 400 that performs a screen accessory control process) to control the focus mechanism based on the focus change time calculated by the focus change time calculation means. It is characterized by doing.

  According to such a configuration, when the projection plane is displaced by operating the projection plane drive mechanism, the focus change calculated based on the required operation time for the operation and the time required for changing the focus position of the focus mechanism By controlling the focus mechanism based on time, the focus adjustment can be performed efficiently, so that a high-quality image with a high visual effect can be quickly displayed on the projection surface after the displacement.

As a preferred embodiment of the present invention,
The control means can cancel the focus change time calculated by the focus change time calculation means (for example, the process in S191 of the focus change request process).

  According to such a configuration, since the focus mechanism can be controlled after canceling the focus change time, the focus adjustment can be performed quickly and efficiently.

  According to the present invention, it is possible to provide a gaming machine capable of promptly projecting a high-quality image with a high visual effect on the projection surface after displacement.

The inclined part B15b is formed to bend obliquely downward and rearward from the rear side of the upper part B15a. The lower part B15c is formed to bend in the horizontal direction from the rear side of the inclined part B15b.

  The upper part B15a of the perforated plate B15 is attached to the side wall parts B13 and B13 of the projector cover B1. Thereby, the perforated plate B15 is arranged so as to cover the front part of the projector cover B1 from the lower side with the upper part B15a and cover the lower part with the inclined part B15b and the lower part B15c from the middle part to the rear part of the projector cover B1. Yes. Further, the inclined portion B15b is disposed so as to surround the inclined surface B2a1 on the lower surface B2a of the projector device B2 when viewed from above. As shown in FIG. 7, the inclination angle of the inclined portion B15b (inclination angle with respect to the horizontal plane) is substantially the same as the inclination angle of the inclined surface B2a1. A front screen mechanism E1 in the screen device C is arranged below the perforated plate B15.

  The front screen mechanism E1 has a front standby position disposed on the upper side that is a standby posture that prohibits the appearance of an image by irradiation light, and a front exposure disposed on the lower side that is an exposure posture that permits the appearance of an image by irradiation light. The front screen mechanism E1 in the standby posture is in an inclined posture close to the inclined portion B15b of the perforated plate B15 in a substantially parallel manner. On the other hand, when the front screen mechanism E1 is in the exposed posture, a large space portion appears below the porous plate B15, and air present in the space portion reaches the porous plate B15 without flow resistance, By passing through the hole B151, it is possible to facilitate the inflow of air into the screen device C and enhance the cooling effect.

  Further, the perforated plate B15 is provided so as to cover the lower surface of the projector cover B1, so that, for example, as shown in FIG. 11, the player's eye position located on the front side is the center in the vertical direction and the horizontal direction of the screen device C. Even if the irradiation unit B is looked up from the position of the line of sight, the inside of the irradiation unit B is prevented from being visually observed by the perforated plate B15.

(Display unit A: Screen device C)
As shown in FIG. 12, the irradiation unit B configured as described above is connected to the upper surface of the screen device C by screw fastening. For example, as described above, screws are screwed into the upper surfaces of the right side plate C2 and the left side plate C3 of the screen device C through the screw holes B131C formed in the protrusion B131 of the projector cover B1. Thereby, the display unit A can unitarily handle the irradiation unit B and the screen device C as a unit.

(Display unit A: Screen device C: Screen mechanism)
Inside the screen housing C10, a plurality of screen mechanisms for causing an image to appear by irradiation of irradiation light from the irradiation unit B are provided so as to switch irradiation targets. Specifically, as shown in FIG. 13, a fixed screen mechanism D, a front screen mechanism E1, and a reel screen mechanism F1 are provided as the plurality of screen mechanisms. The projection planes of the fixed screen mechanism D, the front screen mechanism E1, and the reel screen mechanism F1 have different shapes from each other in order to diversify the image expression. The front screen mechanism E1 and the reel screen mechanism F1 are movable screens whose positions are displaced relative to the projector device B2 and the mirror mechanism B3. The front screen drive mechanism E2 and the reel screen drive mechanism F2 are respectively provided. (See FIG. 20). Note that the front screen mechanism E1 and the reel screen mechanism F1 are larger and heavier in the front screen mechanism E1. For this reason, when the front screen mechanism E1 is driven, a larger driving force is required than when the reel screen mechanism F1 is driven.

(Display unit A: Screen device C: Screen casing C10)
As described above, the screen device C includes the box-shaped screen casing C10. As shown in FIG. 13, the screen casing C10 includes a horizontally disposed bottom plate C1, a right side plate C2 erected at the right end portion of the bottom plate C1, and a left side plate C3 erected at the left end portion of the bottom plate C1. And a back plate C4 erected at the rear end of the bottom plate C1. Accordingly, the right side plate C2, the left side plate C3, and the back plate C4 are connected to the bottom plate C1 by screw fastening, so that the front side where the player is located and the upper side where the irradiation unit B is located are opened. A box-shaped screen casing C10 is formed.

  The bottom plate C1, the right side plate C2, the left side plate C3, and the back plate C4 are individually molded into a predetermined shape, and predetermined functional components such as the fixed screen mechanism D can be positioned and arranged. As a result, even if the unit of the screen device C cannot be shared as a whole, it can be shared in units of plate members of the bottom plate C1, the right side plate C2, the left side plate C3, and the back plate C4. In addition, since the plate member can be partially exchanged, the specification can be easily changed for each model of the gaming machine 1.

(Display unit A: Screen device C: Screen casing C10: Bottom plate C1)
The bottom plate C1 of the screen casing C10 is formed in a flat plate shape that is rectangular when viewed from above. The upper surface of the bottom plate C1 has a central placement portion C11 disposed at the center, and a right placement portion C12 and a left placement portion C13 disposed in the left-right direction with the center placement portion C11 as the center. . These placement parts C11, C12, C13 are formed in a concave shape. The center placement portion C11 places the fixed screen mechanism D so that it can be positioned by fitting the lower end portion of the fixed screen mechanism D. The right mounting portion C12 mounts the right movable body base C5 so as to be positioned by fitting the lower end portion of the right movable body base C5. The left placement portion C13 places the left movable body base C6 so that the left movable body base C6 can be positioned by fitting the lower end portion of the left movable body base C6. In addition, a pattern is three-dimensionally formed by unevenness on the side surface in the left-right direction of each of the right movable body base C5 and the left movable body base C6. That is, the right movable body base C5 and the left movable body base C6 also function as a decorative member. As described above, the fixed screen mechanism D, the right movable body base C5, and the left movable body base C6 can be positioned and arranged on the bottom plate C1.

  Further, the front portion C14 of the bottom plate C1 is bent downward so that the tip portion is positioned below the lower surface of the bottom plate C1. A plurality of through holes C141 are formed in the front portion C14. When the display unit A is assembled while being placed on the intermediate support plate G1 (see FIG. 5) of the cabinet G, the front portion C14 comes into contact with the front surface of the intermediate support plate G1, thereby moving the front portion C14 toward the rear in the cabinet G. It is possible to perform positioning. The display unit A can be assembled and installed from the front side of the cabinet G by being screwed to the front side of the cabinet G through the through hole C141 of the front part C14. It has become.

(Display unit A: Screen device C: Screen casing C10: Right side plate C2, Left side plate C3)
As shown in FIGS. 13 and 14, the right side plate C2 and the left side plate C3 of the screen casing C10 have operation openings C21 and C31. The operation openings C21 and C31 are formed as handles, and the display unit A can be carried by hooking the operation openings C21 and C31. The operation openings C21 and C31 are arranged on the sides of the crank gears E21 and E21 of the front screen drive mechanism E2. The opening portions C21 and C31 for operation are formed in a rectangular shape whose longitudinal direction coincides with the horizontal direction. The opening areas of the operation openings C21 and C31 are set to such an extent that the crank gears E21 and E21 can be manually operated from the outside.

  Thus, when the front screen mechanism E1 at the standby position is manually moved after the display unit A is assembled in the cabinet G, first, the display unit A is taken out from the front side of the cabinet G in which the upper door mechanism UD is opened. . Specifically, an operator located on the front side of the cabinet G releases the screw fastening of the display unit A to the cabinet G and removes the screw. Then, reaching into the cabinet G, the operation openings C21 and C31 of the display unit A are held with both hands, and the display unit A is taken out of the cabinet G. Thereafter, a hand is reached into the screen device C from one operation opening C21 of the detached display unit A, and the crank gear E21 that is visible in the horizontal direction is rotated from the operation opening C21 to thereby lock the front screen. The mechanism E1 can be easily moved from the standby position. When the locked state is released by the movement from the standby position, the front screen mechanism E1 can be quickly rotated to a desired position.

  In the state where the upper door mechanism UD is opened, the hand is reached from the front of the opening of the cabinet G into the space between the side wall G2 of the cabinet G and the right side plate C2 of the screen device C, and the operation opening C21 is reached. The crank gear E21 can be rotated by operating the crank gear E21. In this case, the front screen mechanism E1 can be unlocked without removing the display unit A from the cabinet G.

  Further, a motor housing portion C22 is formed on the right side plate C2. The drive motor F24 of the reel screen drive mechanism F2 (see FIG. 20) is positioned by the motor housing portion C22. Further, the right side plate C2 and the left side plate C3 respectively include a first support portion C23 that rotatably supports the gear shaft E21a of the crank gear E21 in the front screen drive mechanism E2, and an intermediate gear E23 in the front screen drive mechanism E2. A second support portion C24 that rotatably supports the shaft member E3 that is the gear shaft is formed. As described above, the front screen drive mechanism E2 and the reel screen drive mechanism F2 are positioned and arranged by the right side plate C2 and the left side plate C3. The right front screen drive mechanism E2B and the reel screen drive mechanism F2 of the front screen drive mechanism E2 are disposed between the right movable body base C5 and the right side plate C2 in the left-right direction. Further, the left front screen drive mechanism E2A is disposed between the left movable body base C6 and the left side plate C3 in the left-right direction.

(Display unit A: Screen device C: Screen casing C10: Back plate C4)
As shown in FIG. 15, the back plate C4 of the screen casing C10 is formed in a flat plate shape, and a recess CO for positioning and arranging the relay board CK is formed in the lower part of the back surface thereof. The relay substrate CK includes various functional components in the display unit A (for example, the projector device B2, the front screen drive mechanism E2, the reel screen drive mechanism F2, etc.) and various functional components other than the display unit A (sub control substrate SS, which will be described later). ) Is a relay board for relaying wiring (not shown). The relay substrate CK includes a screen drive control substrate CS (see FIGS. 37 and 42) that exchanges signals and the like with the screen drive mechanisms E2 and F2.

  An operation opening C41 is formed in the back plate C4. The operation opening C41 is disposed at the lower right side and faces the intermediate gear E23 of the front screen drive mechanism E2. The operation opening C41 is formed in a size that allows the intermediate gear E23 to be manually operated. Accordingly, when the front screen mechanism E1 at the standby position is manually moved after the display unit A is incorporated into the cabinet G, the display unit A is first removed from the cabinet G. After that, reaching out from the operation opening C41 into the screen device C and rotating the intermediate gear E23 visible in the horizontal direction from the operation opening C41, the locked front screen mechanism E1 can be easily moved from the standby position. Can be moved.

  Further, the back plate C4 is disposed in front of the rear ends of the right side plate C2 and the left side plate C3. Thereby, when the display unit A is placed on the intermediate support plate G1 of the cabinet G, the space GS is formed by the rear wall G3 of the cabinet G, the right side plate C2, the left side plate C3, and the back plate C4 of the screen device C. Will be defined. That is, a gap is secured between the back wall G3 and the back plate C4. As a result, even if the relay board CK is provided on the back surface of the back plate C4, the space GS can prevent the relay board CK from interfering with the back wall G3 of the cabinet G.

  Further, a through hole G11 is formed at a position facing the space GS in the intermediate support plate G1 (see FIG. 5). The through hole G11 is formed so that the opening surrounds the relay substrate CK in a top view. The relay board CK is arranged so that the connector CK1 to which wiring from a device (such as a sub-control board SS described later) housed in the lower space of the cabinet G is connected faces the through hole G11. . Thereby, the electrical connection between the relay substrate CK of the display unit A and the device accommodated in the lower space of the cabinet G is made by inserting the wiring from the device accommodated in the lower space through the through hole G11. This can be done by connecting to CK1.

  Thus, the relay board CK is arranged outside the screen device C, thereby facilitating the wiring work and making it unnecessary to secure an installation space for the relay board CK in the screen device C. The degree of freedom of design in the screen device C is expanded. Moreover, it becomes easy to discharge | emit the heat | fever which generate | occur | produces from the relay board | substrate CK outside the machine via the vent hole G3a (refer FIG. 2) formed in the back wall G3 of the cabinet G. FIG.

  Moreover, the wiring which connects the relay board CK arrange | positioned in the upper space of the cabinet G, and the apparatus accommodated in the lower space of the cabinet G passes through the through-hole G11 formed in the rear part of the intermediate support plate G1. Therefore, it becomes easy to arrange wiring behind various devices in the cabinet G. As a result, the degree of freedom in wiring can be increased.

  Since the relay board CK is arranged at the rear part in the cabinet G, it is difficult for light to reach the relay board CK. As a result, it is difficult to connect the wiring to the connector CK1 of the relay board CK. It can be. Therefore, in order to facilitate the connection of the wiring from the equipment accommodated in the lower space of the cabinet G to the relay board CK, the connector CK1 of the relay board CK passes below the intermediate support plate G1 through the through hole G11. It may be configured to protrude. Further, the color of the connector CK1 may be a color with high light reflectance (for example, white).

  As described above, the fixed screen mechanism D, the right movable body base C5, and the left movable body base C6 are positioned on the bottom plate C1. The drive motor F24 of the reel screen drive mechanism F2 is positioned on the right side plate C2, and the gear shaft E21a and the shaft member E3 of the front screen drive mechanism E2 are positioned on the right side plate C2 and the left side plate C3. The relay substrate CK is positioned with respect to the back plate C4. As described above, the fixed screen mechanism D, the screen driving mechanisms F2 and E2, and the relay substrate CK are positioned and arranged on one of the bottom plate C1, the side plates C2 and C3, and the back plate C4, respectively. Positioned and arranged on different plates. Therefore, even if the display unit A as a whole cannot be shared among the models of the gaming machine 1, it can be shared among the models on a board basis. As a result, the display unit can be manufactured at a lower cost than the case where the display unit is manufactured for each model.

  Moreover, since each board C1-C4 of the screen housing | casing C10 is connected by screw fastening, it can cancel | release connection of each board C1-C4 by loosening a screw. That is, the screen casing C10 is assembled so that the plates C1 to C4 can be replaced. As a result, the functional parts of the display unit can be exchanged on a plate-by-plate basis. Therefore, it is possible to change the specifications of the display unit A while reusing functional parts that are not subject to exchange of the display unit A. .

  As shown in FIGS. 13 and 20, the right movable body base C5 is disposed on the left inner side of the right front screen drive mechanism E2B and the reel screen drive mechanism F2. Further, the left movable body base C6 is disposed on the right inner side of the left front screen drive mechanism E2A. As a result, the right movable body base C5 and the left movable body base C6, which are decorative members, can make it difficult for the player to visually observe the drive mechanisms E2 and F2. As a result, the beauty of the gaming machine 1 can be improved. Moreover, since the recessed part for arrange | positioning the right movable body base C5 and the left movable body base C6 is formed in the baseplate C1, it becomes possible to position these at the baseplate C1 easily.

(Display unit A: Screen device C: Screen position relationship)
As shown in FIG. 16, the fixed screen mechanism D is provided in a fixed state at a fixed exposure position existing in the irradiation direction of the irradiation light. As shown in FIG. 17, the front screen mechanism E1 is provided to be rotatable between a front exposure position and a front standby position. The positional relationship between the fixed exposure position and the front exposure position is set so that the front exposure position is in the irradiation direction of the irradiation light and exists in front of the fixed exposure position. As a result, when the front screen mechanism E1 moves to the front exposure position, the front screen mechanism E1 covers the fixed screen mechanism D from the front so that the image by the irradiation light appears only on the front screen mechanism E1. It is possible. When the front screen mechanism E1 moves to the front standby position, the fixed screen mechanism D is exposed so that an image of the irradiated light can appear on the fixed screen mechanism D. That is, when the front screen mechanism E1 is disposed at the front exposure position, the front screen mechanism E1 becomes a projection target of the projector device B2. On the other hand, when the front screen mechanism E1 is disposed at the front standby position, the fixed screen mechanism D becomes the projection target of the projector device B2.

  As shown in FIG. 18, the reel screen mechanism F1 is provided so as to be rotatable between a reel exposure position and a reel standby position. The positional relationship between the reel exposure position and the fixed exposure position is set so that the reel exposure position is in the irradiation direction of the irradiation light and exists ahead of the fixed exposure position. As a result, when the reel screen mechanism F1 moves to the reel exposure position, the reel screen mechanism F1 covers the fixed screen mechanism D from the front, so that the image by the irradiation light appears only on the reel screen mechanism F1. It is possible. When the reel screen mechanism F1 is moved to the reel standby position, the fixed screen mechanism D is exposed so that an image by irradiation light can appear on the fixed screen mechanism D. That is, when the reel screen mechanism F1 is arranged at the reel exposure position, the reel screen mechanism F1 becomes a projection target of the projector device B2. On the other hand, when the reel screen mechanism F1 is disposed at the front standby position, the fixed screen mechanism D becomes a projection target of the projector device B2.

(Display unit A: Screen device C: Fixed screen mechanism D)
As shown in FIGS. 13 and 14, the fixed screen mechanism D is fixed on the bottom plate C1 of the screen casing C10 by screw fastening. The fixed screen mechanism D includes a front reflection part D1, a right surface reflection part D2, a left surface reflection part D3, and a lower surface reflection part D4. The reflecting surfaces of these reflecting portions D1 to D4 are projection surfaces onto which the irradiation light from the irradiation unit B is projected, and are set at different angles with respect to the optical axis of the irradiation light from the irradiation unit B.

  In addition, if the fixed screen mechanism D is a structure which has a reflective surface of several different angles with respect to the optical axis of irradiation light, it may have a reflective part of 2 surfaces, 3 surfaces, 5 surfaces, for example, Or you may provide the reflective part of the curved or circular-arc-shaped reflective surface in which the curvature center point which becomes an continuously different angle with respect to an optical axis is located in the front side.

  The front reflecting portion D1 has a reflecting surface opposed to the player on the front side, and reflects most of the reflected light from the irradiation unit B arranged in the upper front portion of the fixed screen mechanism D to the front. Is set to The right side reflection part D2 and the left side reflection part D3 are joined to the right side part and the left side part of the front reflection part D1, and are arranged symmetrically about the front reflection part D1. The right side reflection part D2 and the left side reflection part D3 are arranged such that the width between the front end parts is larger than the width in the left-right direction of the front reflection part D1. As a result, the right-side reflection part D2 and the left-side reflection part D3 make it possible to make the reflection direction of the irradiation light with respect to the reflection surface easier to face in the direction of the front reflection part D1, so that a part of the irradiation light appears in front while the image by the irradiation light appears. The light is reflected in the direction of the reflection part D1. In addition, with respect to the lower surface reflection part D4, the reflection direction of the irradiation light with respect to the reflection surface is easily directed toward the front reflection part D1, so that a part of the irradiation light is caused to appear in the direction of the front reflection part D1 while the image by the irradiation light appears. It is designed to reflect.

  In the fixed screen mechanism D, the brightness of the reflecting surface is set lower than the brightness of each reflecting surface of the front screen mechanism E1 and the reel screen mechanism F1. That is, in the fixed screen mechanism D, the amount of light reflected by the reflecting surface of the irradiation light is made smaller than the amount of light reflected by the reflecting surfaces of the front screen mechanism E1 and the reel screen mechanism F1. As a result, the fixed screen mechanism D is prevented from being blurred due to light mixing due to irregular reflection of the reflecting portions D1 to D4. In the fixed screen mechanism D, the brightness of the other reflection parts D2, D3, D4 may be lower than the brightness of the front reflection part D1. In this case, since the reflection of the irradiation light to the front reflection part D1 in the other reflection parts D2, D3, D4 can be reduced, white blur can be reduced while causing an image to appear strongly in the front reflection part D1.

As brightness, Brightness in the L ^* a ^* b ^* color system (L ^* a ^* b ^* color space) or the L ^* u ^* v ^* color system (L ^* u ^* v ^* color space) is adopted. However, any other color can be defined as long as other colors can be expressed by relative values with white as a reference.

  The lightness of the reflection surface of the fixed screen mechanism D and the lightness of the reflection surfaces of the front screen mechanism E1 and the reel screen mechanism F1 are the same as the lightness of the reflection surface of the fixed screen mechanism D and the reflection of the front screen mechanism E1 and the reel screen mechanism F1. If it is lower than the brightness of a surface, it will not specifically limit. For example, the brightness of the reflecting surface of the fixed screen mechanism D may be set to a value lower by about 5 to 25% (or 10 to 20%) than the brightness of the reflecting surfaces of the front screen mechanism E1 and the reel screen mechanism F1.

  In order to make the lightness of the reflection surface of the fixed screen mechanism D lower than the lightness of the reflection surfaces of the front screen mechanism E1 and the reel screen mechanism F1, the color of the paint applied to the base material of the fixed screen mechanism D is changed to the front screen. What is necessary is just to make it black rather than the color of the coating material apply | coated to the base material of the mechanism E1 and the reel screen mechanism F1. For example, a white paint is used as the coating material applied to the base material of the front screen mechanism E1 and the reel screen mechanism F1, and the coating material applied to the base material of the fixed screen mechanism D is the front screen mechanism E1 or the reel screen mechanism F1. What added the black pigment to the coating material apply | coated to a base material should just be used.

  In such a paint, the brightness of the reflection surface of the screen mechanism can be changed by changing the ratio of the white pigment (for example, titanium oxide) and the black pigment (for example, carbon black). For example, the paint applied to the base material of the front screen mechanism E1 and the reel screen mechanism F1 includes only a white pigment among white pigment and black pigment, and the paint applied to the base material of the fixed screen mechanism D includes Both a white pigment and a black pigment may be included. Further, the ratio of the black pigment to the white pigment (for example, 5 to 25% (or 5% to 25%) (or the paint applied to the fixed screen mechanism D is higher than the paint applied to the base material of the front screen mechanism E1 and the reel screen mechanism F1. It may be increased by about 10 to 20%). In addition, as a coating material applied to the base material of these screen mechanisms, a conventionally known screen coating material can be appropriately employed and can be adjusted according to a screen type (for example, a diffusion type or a reflection type). .

  Note that the black pigment is not dispersed in the coating material applied to the base material of the fixed screen mechanism D, but before the base material of the fixed screen mechanism D is molded. By doing so, the base material itself may be colored to lower the brightness of the base material itself.

  Further, from the viewpoint of preventing irregular reflection of light, members constituting the screen casing C10 such as peripheral walls (the bottom plate C1, the right side plate C2, the left side plate C3, and the back plate C4), and the interior of the screen casing C10. It is desirable that the brightness of the other members (members other than the screen) disposed in the panel is also lowered. The brightness of these members is desirably lower than the brightness of the reflecting surface of the fixed screen mechanism D. For example, it is not necessary to consider that an image is projected as a screen for the surrounding wall. The lower the better. That is, it is desirable that the color of the surrounding wall is closer to black.

(Display unit A: Screen device C: Front screen mechanism E1)
As shown in FIG. 19, the front screen mechanism E1 includes a rectangular front screen member E11 having a projection surface E11a on the entire surface, and a front screen support base E12 having patterns such as the first pattern surface E12a on both surfaces. Have. The front screen member E11 is formed by applying screen paint to a thin flat panel. Thereby, as for the front screen member E11, the projection surface E11a is formed in flat shape.

  On the other hand, the front screen support E12 has a holding recess E121 that holds the front screen member E11. The holding recess E121 has an opening shape similar to that of the projection surface E11a of the front screen member E11 in a slightly enlarged state, and accommodates the entire front screen member E11. In addition, the holding recess E121 is set in two stages of a deep part and a shallow part. The shallow portion is realized by a stepped portion E121a formed at the peripheral portion of the front screen support base E12 and a stepped portion E121b formed linearly at both ends in the short direction passing through the center portion.

  Accordingly, the front screen member E11 accommodated in the holding recess E121 is abutted and supported by the stepped portion E121a at the peripheral edge and the linear stepped portion E121b passing through the central portion, and is separated from the remaining deep portion. It is in a state. As a result, the deformation of the front screen support E12 in the deep portion is prevented from deforming the front screen member E11 and causing distortion on the projection surface E11a.

  Further, the front screen support E12 has a first pattern surface E12a in a partial region around the projection surface E11a. The first pattern surface E12a is visible to the player in front when the front screen mechanism E1 is positioned at the front exposure position. Further, the front screen support E12 has a second pattern surface E12b on the entire surface opposite to the first pattern surface E12a. The second pattern surface E12b is visible to the player in front when the front screen mechanism E1 is positioned at the front standby position. In these first pattern surface E12a and second pattern surface E12b, for example, a pattern related to a game effect is three-dimensionally formed by unevenness.

  The front screen member E11 and the front screen support E12 configured as described above are formed separately and then integrated by bonding with an adhesive. Thus, the front screen mechanism E1 is mechanically separated from the front screen member E11 even if sink marks may occur due to molding shrinkage or the like when forming a pattern or the like on the front screen support base E12. Therefore, it is possible to prevent the front screen member E11 from being distorted due to sink marks on the projection surface E11a.

  Note that the method for fixing the front screen member E11 and the front screen support E12 is not limited to bonding with an adhesive, and any method such as screw fastening may be employed.

  The flat panel constituting the front screen member E11 and the front screen support E12 are each produced by injection molding. As a material of the flat panel constituting the front screen member E11 and the front screen support base E12, a thermoplastic resin (for example, ABS resin or the like) that can cause sink marks when injection molding is performed is appropriately adopted. it can.

(Display unit A: Screen device C: Front screen drive mechanism E2)
The front screen mechanism E1 is rotatable by the driving force of the front screen drive mechanism E2. As shown in FIGS. 13 and 14, the front screen drive mechanism E2 includes a left front screen drive mechanism E2A connected to the lower surface of the left end of the front screen mechanism E1, and a right connected to the lower surface of the right end of the front screen mechanism E1. And a front screen drive mechanism E2B.

  As shown in FIG. 17, the front screen mechanism E1 is configured to be inclined upward from the rear end toward the front end when the front screen mechanism E1 is disposed at the front standby position (in the standby posture). ing. The inclination of the front screen mechanism E1 is substantially parallel to the inclined portion B15b of the perforated plate B15 and the inclined surface B2a1 on the lower surface B2a of the projector device B2.

  As described above, the posture of the front screen mechanism E1 when placed at the front standby position is set to an inclined posture in which the front screen mechanism E1 is inclined upward from the rear end portion toward the front end portion, thereby being parallel to the horizontal plane. Compared to the case of the posture, it is possible to suppress the irradiation light irradiated by the irradiation unit B from being obstructed by the front screen mechanism E1. Thereby, the vertical position of the front screen mechanism E1 when placed at the front standby position can be brought closer to the fixed screen mechanism D. As a result, the front screen mechanism E1 can be enlarged even in a limited space of the display unit A. In addition, since the lower surface B2a of the projector device B2 has the inclined surface B2a1 as described above, the vertical position of the front screen mechanism E1 when placed at the front standby position is set with respect to the projector device B2. Can be closer. As a result, the front screen mechanism E1 can be further increased in size.

  As shown in FIG. 14, the right front screen drive mechanism E2B has a crank member E22, a crank gear E21, an intermediate gear E23, a motor shaft gear E24, and a drive motor E25. The crank member E22 in the right front screen drive mechanism E2B has an upper end (one end) located at the upper position when the front end is disposed at the front exposed position (in the exposed posture) on the back of the right end of the front screen mechanism E1. It is connected to.

  The crank member E22 is pivotally supported by the right movable body base C5 (see FIG. 13) at an intermediate position. As a result, the crank member E22 can rotate the upper end portion and the lower end portion (the other end portion) with the intermediate position as the rotation center. This intermediate position coincides with the rotation center axis of the front screen mechanism E1.

  As described above, the rotation center axis of the front screen mechanism E1 is disposed above the center position of the front screen mechanism E1 disposed at the front exposure position. The crank member E22 has an upper end portion (one end portion) connected to a position where the upper end portion (one end portion) becomes an upper portion when the front screen mechanism E1 is disposed at the front exposure position (in the exposure posture) on the rear surface of the right end portion. . With the above configuration, the operation range between the front standby position and the front exposure position in the front screen mechanism E1 can be reduced, so that the front screen mechanism E1 can be increased in size.

  A slide groove (not shown) is formed in the lower region of the crank member E22. The slide groove is formed to have a U shape when viewed from the side. A slide member E26 (see FIG. 14) is movably engaged with the slide groove. That is, the slide member E26 is always in contact with the slide groove. The slide member E26 is rotatably supported at an eccentric position of the crank gear E21. As shown in FIG. 13, the gear shaft E21a of the crank gear E21 is rotatably supported by the right movable body base C5 and the first support portion C23 of the right side plate C2. The gear shaft E21a of the crank gear E21 has a line segment connecting the gear shaft E21a and the eccentric position when the front screen mechanism E1 is in the standby posture or the exposed posture, and the center position of the crank member E22 and the slide member E26. Are set so as to have an orthogonal relationship to the line segment connecting the two.

  Thereby, when the front screen mechanism E1 is in the standby posture or the exposed posture, even if a force is applied in a direction in which the lower region of the crank member E22 is rotated, the gear shaft E21a is applied in the direction in which all components of the force are applied. Exists and acts as a fixed end, so that the slide member E26 does not move. As a result, a truss structure is formed by a three-joint link having zero degrees of freedom with the intermediate position of the crank member E22 and the gear shaft E21a of the crank gear E21 as the fixed end and the slide member E26 as the free end. Even if it is pushed by hand, the front screen mechanism E1 does not move because the crank member E22 and the crank gear E21 act as a strong brake.

  An intermediate gear E23 is meshed with the crank gear E21. The intermediate gear E23 is pivotally supported by the right movable body base C5 and the second support portion C24 of the right side plate C2. A motor shaft gear E24 is meshed with the intermediate gear E23. The motor shaft gear E24 is connected to the drive shaft of the drive motor E25. Thereby, the right front screen drive mechanism E2B can transmit the rotational driving force of the drive motor E25 to the crank gear E21 via the motor shaft gear E24 and the intermediate gear E23.

  Here, all the components of the rotational driving force applied to the crank gear E21 coincide with the tangential direction of the turning locus of the slide member E26. When the front screen mechanism E1 is in the standby posture or the exposed posture, a line segment connecting the gear shaft E21a and the eccentric position of the slide member E26 connects the intermediate position of the crank member E22 and the center point of the slide member E26. Since it is set to have a relationship orthogonal to the line segment, the tangential direction of the turning locus is parallel to the slide groove of the crank member E22. Accordingly, when the front screen mechanism E1 is in the standby posture or the exposed posture, when the rotational driving force is applied to the crank gear E21, the crank gear E21 starts to rotate easily.

  When a rotational driving force is applied to the crank gear E21, the slide member E26 provided at the eccentric position is movable along the slide groove, so that the intermediate position of the crank member E22 and the gear shaft of the crank gear E21 are provided. A one-degree-of-freedom two-joint link is formed in which E21a is a fixed end and the slide member E26 is a free end that is movable along the slide groove. When the slide member E26 rotates, the slide member E26 slides along the slide groove so that the crank member E22 rotates about the intermediate position, and the upper region of the crank member E22 rotates. Become. As a result, the front screen mechanism E1 moves between the front standby position and the front exposure position.

  In the present embodiment, the drive motor E25 is a stepping motor, and is electrically connected to the sub control board SS via the relay board CK and the sub relay board SN (see FIG. 34). Drive controlled. The drive motor E25 may be connected to the main control board MS via the relay board CK and driven and controlled by the main control board MS.

  Further, the moving speed of the front screen mechanism E1 gradually accelerates from 0 in the stopped state in the standby posture or the exposed posture, gradually decreases after reaching the maximum speed in the intermediate posture between the standby posture and the exposed posture, When the exposure posture or the standby posture is reached, the stop state becomes zero again. Thus, the rotation can be started and stopped in a state where the angular acceleration of the crank gear E21 is small (moment of inertia), so that the torque required for the crank gear E21 can be reduced, and as a result, the drive mechanism ( It is possible to reduce failures and wear due to overloading of the intermediate gear E23, the motor shaft gear E24, and the drive motor E25).

  The right front screen drive mechanism E2B configured as described above has the same configuration as the left front screen drive mechanism E2A except for the motor shaft gear E24 and the drive motor E25. The left front screen drive mechanism E2A and the right front screen drive mechanism E2B are arranged symmetrically. The intermediate gear E23 of the left front screen drive mechanism E2A and the intermediate gear E23 of the right front screen drive mechanism E2B are connected via a shaft member E3 (see FIG. 13).

  In the above configuration, when the drive motor E25 is driven, the motor shaft gear E24 is rotated. As the motor shaft gear E24 rotates, the intermediate gears E23 and E23 and the shaft member E3 of the left front screen drive mechanism E2A and the right front screen drive mechanism E2B rotate together. Then, the crank gears E21 and E21 are rotated in conjunction with the rotation of the intermediate gears E23 and E23, whereby the front screen mechanism E1 is rotated around the rotation center axis, and the front standby position and the front It moves between exposure positions.

  As described above, by connecting the intermediate gears E23 and E23 of the left front screen drive mechanism E2A and the right front screen drive mechanism E2B by the shaft member E3, the rotational driving force of the drive motor E25 is applied to the two crank members E22. It becomes possible to transmit evenly. Therefore, compared with the case where these intermediate gears E23 and E23 are not connected by the shaft member E3, it is possible to prevent the driving load from being concentrated on one of the two crank members E22. Further, since the drive motor E25 is provided in the right front screen drive mechanism E2B arranged on the right side of the fixed screen mechanism D, the arrangement of the fixed screen mechanism D is not hindered.

  In addition, the shaft member E3 is not used as the rotation shaft of the front screen mechanism E1. For this reason, the freedom degree of arrangement | positioning of the shaft member E3 increases, and it becomes possible to arrange | position the shaft member E3 so that arrangement | positioning of other supplements, such as the fixed screen mechanism D, may not be inhibited. As a result, it is possible to increase the degree of freedom of the arrangement of the extra items while maintaining the rotation range and size of the front screen mechanism E1 at a desired level.

  Further, since the shaft member E3 is disposed behind the fixed screen mechanism D, the light projected on the fixed screen mechanism D is not hindered by the shaft member E3. Further, since the rotation center axis of the front screen mechanism E1 is disposed forward of the rear end position of the fixed screen mechanism D, it is compared with the case where it is disposed rearward of the rear end position of the fixed screen mechanism D. Thus, the length between the front screen mechanism E1 and the rotation center axis (the length of the crank member E22) can be shortened. For this reason, even when the space in the cabinet G is limited and the display unit A cannot be enlarged, the size of the front screen mechanism E1 can be maintained to a desired level.

(Display unit A: Screen device C: Reel screen mechanism F1)
As shown in FIG. 18, the reel screen mechanism F1 is a curved flat plate. The reel screen mechanism F1 has a circular arc shape when viewed from the side, which is curved in a shape that approximates the rotation direction. On the surface of the reel screen mechanism F1, a pattern is formed on the peripheral portion, and an inner peripheral area of the peripheral portion is a projection surface F1a. The projection plane F1a is an arcuate surface that protrudes upstream in the irradiation direction of light from the projector device B2 when the reel screen mechanism F1 is disposed at the reel exposure position. In addition, a pattern is formed on the rear surface on the rotation center side in the reel screen mechanism F1. The pattern on the back surface is made visible to the player in front when the reel screen mechanism F1 is positioned at the reel standby position.

  The reel screen mechanism F1 is rotatable between the reel standby position and the reel exposure position by the driving force of the reel screen drive mechanism F2. When the reel screen mechanism F1 is positioned at the reel exposure position, the projection surface F1a can appear an image by irradiation with irradiation light.

(Display unit A: Screen device C: Reel screen drive mechanism F2)
As shown in FIG. 20, the reel screen drive mechanism F2 has two arm members F21 (not shown on the right side), an arcuate gear F22, a motor shaft gear F23, and a drive motor F24. One end of each of the two arm members F21 is connected to the back surface of the right end portion and the back surface of the left end portion of the reel screen mechanism F1. A support shaft F21a (not shown on the left side) is formed on the outer surface of the other end of the two arm members F21 so as to protrude outward in the left-right direction. These support shafts F21a are rotatably supported by the right movable body base C5 and the left movable body base C6, respectively. As a result, the two arm members F21 can rotate about the support shaft F21a. These support shafts F21a coincide with the rotation center axis of the reel screen mechanism F1.

  The arcuate gear F22 is fixed to the tip of the support shaft F21a arranged on the right side. A motor shaft gear F23 is meshed with the arcuate gear F22. The drive shaft of the drive motor F24 is connected to the motor shaft gear F23. In the present embodiment, the drive motor F24 is a stepping motor, and is electrically connected to the sub control board SS via the relay board CK and the sub relay board SN (see FIG. 34). Drive controlled. The drive motor F24 may be connected to the main control board MS via the relay board CK and driven and controlled by the main control board MS.

  In the above configuration, when the drive motor F24 is driven under the control of the sub-control board SS, the motor shaft gear F23 rotates. As the motor shaft gear F23 rotates, the arcuate gear F22 rotates. Then, the arm member F21 is rotated in conjunction with the rotation of the arcuate gear F22, whereby the reel screen mechanism F1 is rotated around the rotation center axis, and the reel standby position and the reel exposure position are set. Will work between.

(Display unit A: Screen device C: Sensor mechanism)
As described above, the operation ranges of the front screen mechanism E1 and the reel screen mechanism F1 partially overlap each other (see FIGS. 17 and 18). The front screen mechanism E1 and the reel screen mechanism F1 are driven by different drive mechanisms E2 and F2, respectively. That is, the driving of the front screen mechanism E1 and the reel screen mechanism F1 is not linked (synchronized). Therefore, in order to prevent interference (contact) between the screen mechanisms E1 and F1, it is necessary to grasp the positions of the screen mechanisms E1 and F1. Therefore, in the present embodiment, the sub control board SS (see FIG. 34) grasps the position of the front screen mechanism E1 based on the number of steps of the drive motor E25 from the origin position with the front standby position as the origin position. ing. Similarly, the reel standby position is set as the origin position, and the position of the reel screen mechanism F1 is grasped based on the number of steps of the drive motor F24 from the origin position.

  However, if the operation of the front screen mechanism E1 or the reel screen mechanism F1 is not normally performed, or if the front screen mechanism E1 or the reel screen mechanism F1 is manually moved while the power is shut off, the sub-control board SS. Cannot grasp the exact positions of the front screen mechanism E1 and the reel screen mechanism F1. If the front screen mechanism E1 and the reel screen mechanism F1 are operated in such a situation, they may interfere with each other.

  Therefore, in the present embodiment, the screen device C includes a sensor mechanism (not shown) for detecting the positions of the front screen mechanism E1 and the reel screen mechanism F1. Then, the sub-control board SS performs a return operation for returning the screen mechanisms E1 and F1 to the origin position (standby position) based on the detection result from the sensor mechanism.

  For example, as described above, each of the front standby position and the reel standby position is arranged in the overlapping range in the operation range of the screen mechanisms E1 and F1, so when the front screen mechanism E1 is arranged in the front exposure position, The reel screen mechanism F1 is not disposed at the reel exposure position. For this reason, when the sensor mechanism detects that the front screen is present at the front exposed position, it indicates that the reel screen mechanism F1 is not present at the reel exposed position.

(Screen surface processing)
Next, screen surface processing will be described. A screen to be projected, such as a front reflecting portion D1, a right reflecting portion D2, a left reflecting portion D3, and a lower reflecting portion D4 of the fixed screen mechanism D, a projection surface E11a of the front screen member E11, and a projection surface F1a of the reel screen mechanism F1. In order to achieve an appropriate performance, graining is applied. The wrinkle processing is processing in which wrinkles (wrinkle patterns) are formed on the surface. The screen or the like to be projected is molded using a mold that has been subjected to a textured process, whereby a wrinkle pattern is formed on the surface of the screen or the like to be projected. Such a wrinkle pattern on the surface can effectively prevent the reflection of the light source, and can realize a good projection image.

  The texture processing includes a pattern called “pear texture”. In this embodiment, for example, a pear texture pattern having a mean depth of about 25 μm to 30 μm and a draft gradient of 3% or more (pear texture No. 5). Is preferred.

  Moreover, as surface processing of a screen etc., in order to implement | achieve moderate performance, 2 layer coating is given. Two-layer coating means that paints having different characteristics are applied to the top and bottom (in two layers). For example, a high-brightness paint having high reflectivity (for example, 2P-600 silver which is a “super bright silver” metal-like paint) is used for the undercoat, and a matte paint (for example, “matte” is used for the topcoat. HG-650 white) which is “white” can be used. Also, about 5% matting agent (silica) can be added to HG-650 white.

  In such coating, the film thickness of the top coat is, for example, 22 to 23 μm, and the film thickness of the undercoat is, for example, about 1 μm. By such coating, the glossiness at a gloss of 60 ° is 4 to 5.

  2P-600 Silver uses evaporated aluminum as the aluminum pigment, and the weight concentration (PWC) of the aluminum pigment in the coating is set to 20-30%, which is higher than that of general silver paint, and it has a higher gloss. Indicates the value (reflection performance). The composition of HG-650 white is 20-30% resin, 30-40% titanium oxide, 5-10% silica as a matting agent, 0.5-2% additive, and solvent. 30 to 40%.

  In addition, as a top coat paint, a paint in which glass or resin beads having various average particle diameters as a matting agent are added to HG-650 white in a predetermined ratio, or a paint in which silica is added to the beads is added. It can also be used. Also, HG-650F clear or a paint in which beads having various average particle diameters as a matting agent are added to the HG-650F clear in a predetermined ratio can be used. The film thickness can be variously adjusted, for example, up to 16 to 23 μm. The composition of HG-650F clear is 20-30% resin, 2-5% silica as matting agent, 0.5-2% additive, and 60-70% solvent.

  Further, as other undercoat paint, HG-650 white, or a paint obtained by adding glass-based or resin-based beads having various average particle diameters to the HG-650 white as a matting agent in a predetermined ratio can also be used. Also, the film thickness can be variously adjusted, for example, from 1 to 21 μm.

  As described above, by forming the screen to be projected by embossing or applying a two-layer coating, the reflection of the light source can be effectively prevented, and a better projection image can be displayed. Can be realized. Further, the above-described two-layer coating can be applied to a screen or an accessory that has been subjected to the texture processing. Moreover, although materials, such as a screen used as a projection object, are black or white ABS resin and transparent polycarbonate resin, for example, they are not restricted to these.

(Display Unit A: Irradiation Unit B: Electrical and Optical Configuration of Projector Device B2)
As shown in FIG. 21, the projector device B2 includes a projector control board B23, an optical mechanism B24, and a relay board CK as electrical components. A sub-control board SS, which will be described later, is connected to the projector device B2 via a relay board CK. Although not shown in FIG. 21, the relay substrate CK and the sub control substrate SS are connected via a scaler substrate SK (see FIGS. 37 and 43) described later. The sub-control board SS controls the projector control board B23 according to the screen or the effect operation of the accessory, and projects the irradiation light on the screen or the accessory via the optical mechanism B24 as a visual effect. Display video. Further, in the assembly process of the display unit A and the like, an adjustment PC (personal computer) 1000 is connected to the projector control board B23 (see FIGS. 30 and 37) of the projector device B2. The adjustment PC 1000 is used to adjust the position of irradiation light projected by the projector device B2 and to perform initial focus setting (details will be described later). In this embodiment, the adjustment PC 1000 is used as the adjustment device of the projector device B2. However, as the adjustment device of the projector device B2, a tablet PC or a so-called smartphone installed with an adjustment program (application software) is used. Alternatively, a dedicated terminal device may be used.

  The projector control board B 23 includes a control LSI 230, an EEPROM (registered trademark) 231, a DLP (registered trademark) control circuit 232, and an LED driver 233. As shown in FIG. 33, the optical mechanism B24 includes LED light sources 240R, 240G that emit light of R (red), G (green), and B (blue) as components disposed around the lens unit B21. 240B, DMD 241, and a focus mechanism 242 for performing focus adjustment on the projection lens 210 of the lens unit B21.

  The control LSI 230 controls the DLP control circuit 232 to project the irradiation light based on the command from the sub control board SS. The control LSI 230 controls the focus mechanism 242 and moves the projection lens 210 in the optical axis direction based on a command from the sub-control board SS, thereby performing focus adjustment when projecting the irradiation light. The EEPROM 231 stores data related to setting / adjustment of the projector device B2 by the control LSI 230. Although not particularly illustrated, the control LSI 230 includes a ROM in which a control program and the like are stored, and a DRAM that is used in a work area related to setting and adjustment of the projector apparatus B2.

  The DLP system of the projector apparatus B2 mainly includes a DLP control circuit 232, an LED driver 233, LED light sources 240R, 240G, 240B, and a DMD 241 of the optical mechanism B24.

  The DMD 241 is obtained by integrating mirrors corresponding to pixels according to display resolution on the main surface of a semiconductor chip. The DMD 241 is configured such that each mirror is inclined by + 10 ° or −10 ° around an axis along a diagonal line with respect to the main surface due to an electrostatic field effect of a memory element immediately below each mirror. With such a configuration, each mirror of the DMD 241 is switched between an ON state (a state in which light is reflected in a predetermined direction) and an OFF state (a state in which light is reflected outside a predetermined direction). That is, when each mirror of the DMD 241 is in an ON state, light incident from the LED light sources 240R, 240G, and 240B via a dichroic mirror (not shown) is again guided to the lens unit B21 via the dichroic mirror and the like. In the state, the light incident from the LED light sources 240R, 240G, and 240B through the dichroic mirror or the like is reflected toward the direction other than the lens unit B21.

  The DLP control circuit 232 controls the LED driver 233 that drives the LED light sources 240R, 240G, and 240B, and performs DMD 241 in a time-division manner on the RGB colors from the LED light sources 240R, 240G, and 240B via a dichroic mirror (not shown). To enter. At this time, the DLP control circuit 232 determines at which timing the mirror corresponding to which pixel is turned on or off according to the image to be projected. To determine whether the light is reflected in a predetermined direction, and the ON / OFF state of each mirror of the DMD 241 is controlled.

  Under such control of the DLP control circuit 232, the light reflected in the DMD 241 in a predetermined direction travels to the lens unit B21, passes through the projection lens 210, and enters the mirror mechanism B3. Finally, the light is reflected by the mirror mechanism B3. By being reflected, it is guided to the projection target. Thereby, irradiation light is projected with respect to the screen used as a projection target, and an accessory, and the image | video according to production is formed.

  In the present embodiment, the projector device B2 is configured as a so-called DLP projector. Further, the projector device B2 increases the projection distance to the projection target by turning back the irradiation light by the mirror mechanism B3, and makes the projection distance of the irradiation light as short as possible by setting the contrast ratio to 1000: 1, for example. ing. Thereby, the display unit A including the projector device B2 is configured to be cheaper and smaller, and is easily mounted in a limited space in the cabinet G of the gaming machine 1.

(Display unit A: Irradiation unit B: Mechanical configuration of projector device B2)
As shown in FIGS. 22 and 23, the projector apparatus B2 includes a case B22, a lens unit cover B222, an under cover B223, an upper pedestal B220, and a lower pedestal B221 as components constituting the exterior. A lens unit cover B222 is attached to the front opening B22k of the case B22. The under cover B223 is disposed on the lower surface of the case B22 so as to cover it. The under cover B223 is supported by the lower pedestal B221 via the stay B223a and is also fixed to an appropriate lower surface of the case B22. The projector device B2 is attached to the lower surface of the upper wall portion B12 (see FIG. 8) of the projector cover B1 via the upper pedestal B220 and the lower pedestal B221. In the present embodiment, the upper pedestal B220 is fixed to the lower surface of the upper wall B12, and the lower pedestal B221 is attached to the upper end of the case B22 so as to cover the upper surface opening of the case B22. Lower pedestal B221 is connected. The procedure for adjusting the attachment of the projector apparatus B2 will be described later.

  As shown in FIG. 23, FIG. 24, and FIG. 33, the projector apparatus B2 includes LED substrates 240Ra, 240Ga, 240Ba, and DMD 241 on which a lens unit B21, LED light sources 240R, 240G, and 240B are mounted as internal components. DMD board 241a, a plurality of heat sinks 243R, 243G, 243B, 243D, intake fans 244A (FAN1), 244B (FAN2), exhaust fans 245 (FAN3), and projector control board B23. The case B22 accommodates the lens unit B21 while the projection lens 210 of the lens unit B21 is covered by the lens unit cover B222, and also includes LED substrates 240Ra, 240Ga, 240Ba, a DMD substrate 241a, and a plurality of heat sinks 243R, 243G, 243B. , 243D, intake fans 244A and 244B, and exhaust fan 245 are accommodated. The projector control board B23 is fixed to the lower surface of the case B22. Although not particularly shown in FIG. 33 and the like, a temperature sensor B25 (see FIGS. 21 and 37) made of, for example, a thermistor is mounted on the LED substrates 240Ra, 240Ga, 240Ba and the DMD substrate 241a. These temperature sensors B25 detect temperatures near the LED light sources 240R, 240G, and 240B and the lens unit B21, and output a temperature detection signal to the projector control board B23.

  The lens unit B21 includes an optical case B21a that houses a dichroic mirror, a reflector, and the like (not shown), a lens group 210A that includes the projection lens 210, a lens holder B21b that is provided at the front of the optical case B21a while holding the lens group 210A, and A focus mechanism 242 provided on the front right side of the optical case B21a is provided so that a part of the lens holder B21b can be moved in the optical axis direction (front-rear direction). The optical case B21a is provided with openings that allow the LED light sources 240R, 240G, and 240B and the DMD 241 to face from the outside to the inside. The lens holder B21b has a rear portion fixed to the front portion of the optical case B21a, and the front portion is moved relative to the rear portion in the front-rear direction (optical axis direction) by the focus mechanism 242. The projection lens 210 is held. The lens unit B21 is provided with a so-called lens shift mechanism (not shown). By using this lens shift mechanism, the horizontal and vertical positions of the projected image can be finely adjusted. is there.

  The focus mechanism 242 is for focusing while changing the focal length of the projection lens 210 with respect to the reflection surfaces of the reflection portions D1 to D4 and the projection surfaces E11a and F1a that are displaced with respect to the projector device B2. The focus mechanism 242 is disposed along the optical axis direction of the projection lens 210 with a rack member 242A that can move integrally with the front portion of the lens holder B21b that holds the projection lens 210, and is screwed with the rack member 242A. The lead screw 242B is rotatable while being rotated, and the focus motor 242C is configured to rotate the lead screw 242B. The focus motor 242C is connected to the control LSI 230 of the projector control board B23.

  For example, when the focus motor 242C rotates the lead screw 242B in a predetermined direction, the rack member 242A moves to the front side by a feed screw operation, and the projection lens 210 moves to the front side together with the rack member 242A. Since the focal length is relatively long, the focal point (focus position) can be adjusted far away. On the other hand, when the focus motor 242C rotates the lead screw 242B in the direction opposite to the predetermined direction, the rack member 242A moves to the rear side by the feed screw operation, and the projection lens 210 is integrated with the rack member 242A. As a result of the movement, the focal point (focus position) is adjusted closer to a shorter focal length.

  According to such a focus mechanism 242, the focal length can be dynamically changed in conjunction with the movement of the projection planes E11a and F1a. For example, when the projection target is changed from the projection plane E11a to the projection plane F1a, or vice versa, the optical path length from the projection lens 210 to each projection target differs to some extent. The focal point (focus position) can be changed statically so as to have an appropriate focal length according to the length.

  The front portion of the lens holder B21b and the projection lens 210 are covered with a lens unit cover B222. The lens unit cover B222 is provided with a light-transmitting surface B222a that transmits the irradiation light from the projection lens 210, and the light emitted from the projection lens 210 passes through the light-transmitting surface B222a and proceeds to the mirror mechanism B3. .

  The LED board 240Ra is disposed adjacent to the right side of the rear portion of the optical case B21a in the case B22, and the LED light source 240R faces the inside of the optical case B21a. The LED substrate 240Ga is disposed in the case B22 so as to be adjacent to the back side of the rear portion of the optical case B21a, and the LED light source 240G faces the inside of the optical case B21a. The LED board 240Ba is disposed in the case B22 so as to be adjacent to the left side of the rear portion of the optical case B21a, and the LED light source 240B faces the inside of the optical case B21a. The DMD substrate 241a is disposed in the case B22 so as to be adjacent to the left side surface of the optical case B21a, and faces the DMD 241 inside the optical case B21a. Here, in the present embodiment, the LED light sources 240R, 240G, and 240B and the DMD 241 have heat generation characteristics that the LED light source 240G and the LED light source 240B tend to be relatively high, while the LED light sources 240R and the DMD 241 are relatively The trend is low.

  As shown in FIG. 24A, the focus mechanism 242 is disposed on the right side of the lens holder B21b, and the projection lens 210 is disposed on the front portion of the lens holder B21b. The front portion of the lens holder B <b> 21 b can be moved in the optical axis direction of the projection lens 210 by the focus mechanism 242. Although the details of the focus mechanism 242 are omitted, the focus mechanism 242 includes a stepping motor, a lead screw, a carriage, and the like, and is configured to be able to move the front portion of the lens holder B21b in the optical axis direction.

  In other words, the projection lens 210 is integrated with the front portion of the lens holder B21b and can be moved by the focus mechanism 242. As shown in FIG. 24A, the projection lens 210 moves from the rear side toward the front side along the optical axis direction. Or, it moves from the front side toward the rear side.

  As shown in FIG. 24A, light from the LED light sources 240R, 240G, and 240B reaches the DMD 241 via a collimator, a dichroic mirror, and the like (not shown), and is reflected by the DMD 241 and then the lens group 210A by the dichroic mirror and the like. And finally exits through the projection lens 210.

  As described above, the projection lens 210 is configured to move in the optical axis direction. As a result, focus adjustment is performed, and a clear and focused image is displayed on the screen or the accessory whose position has been changed by movement.

  Such a projector device B2 is controlled by the sub-control board SS so that video data relating to the video such as effects is transmitted from the sub-control board SS, and the video is projected onto a screen or an accessory. On the other hand, the sub-control board SS moves the screen mechanisms E1, F1 according to the contents of effects by controlling the screen drive mechanisms E2, F2.

  Here, the sub-control board SS controls the projector device B2 according to the movement of the screen mechanisms E1 and F1 due to the effect, and the projection surfaces E11a and F1a of the moved screen mechanisms E1 and F1 and the projection surface of the fixed screen mechanism D. The focus is adjusted so that the image is projected clearly.

Here, in this embodiment, the heat sinks 243R, 243G, 243B, and 243D have fin outer sizes that are relatively large for the heat sink 243R and the heat sink 243G, but relatively small for the heat sink 243B and the heat sink 243D. These heat sinks 243R, 243G, 243B, and 243D dissipate heat generated in each of the LED substrates 240Ra, 240Ga, 240Ba and the DMD substrate 241a into the air, so that the temperature of the optical element and the substrate is changed until the optical characteristics are largely changed. Dissipate heat efficiently so as not to raise the temperature. The heat sinks 243R, 243G, 243B, and 243D, which are heat radiating members, are made of an aluminum material having high heat conductivity in order to enhance the heat radiating effect, and have a plurality of heat radiating fins in order to increase the contact area with air.

  The intake fan 244A is disposed so as to be close to the back surface of the right front portion of the case B22, and is close to the heat sink 243R. The intake fan 244B is disposed so as to be close to the back surface of the left side portion of the case B22, and is close to the heat sink 243D. The exhaust fan 245 is disposed so as to be close to the back surface of the rear portion of the case B22, and is close to the heat sink 243G.

  Here, as shown in FIGS. 31 and 32, an intake port B22A is provided at the right front portion of the case B22 to which the intake fan 244A is adjacent, and the heat sink 243R is adjacent to the intake port B22A. An exhaust port B22E is provided at the right rear portion of the case B22. An intake port B22B is provided in a part of the left side of the case B22 close to the intake fan 244B, and the other part of the left side of the case B22 is arranged in the case B22 so as to be aligned with the intake port B22B. The air inlet B22C is provided so that the air reaches the three heat sinks 243G, 243B, 243D through the empty space S. An exhaust port B22D is provided at the rear of the case B22 where the exhaust fan 245 is close.

  That is, as shown in FIG. 33, in the case B22 of the projector B2, the air is forcibly sucked from the air inlet B22A by the air intake fan 244A and then exhausted from the air outlet B22E while taking heat from the heat sink 243R. An air flow path P1 is formed as an air flow. Further, in the case B22, after the air is forcibly sucked from the air inlet B22B by the air intake fan 244B, the heat is taken from the heat sink 243D, the heat sink 243B, and the heat sink 243G, and the air is forced from the air outlet B22D by the exhaust fan 45. An air flow path P2 is formed as a flow of air exhausted in the air. Further, in the case B22, an air flow path is a flow of air that is forcibly exhausted from the exhaust port B22D by the exhaust fan 45 while taking heat mainly from the heat sink 243G or the heat sink 243B after being sucked from the intake port B22C. P3 is formed.

  The projector control board B23 is attached to the lower surface of the case B22 while being covered with the under cover B223. A control LSI 230, an EEPROM 231, a DLP control circuit 232, an LED driver 233, and the like are mounted on the projector control board B23. The projector control board B23 is electrically connected to the LED boards 240Ra, 240Ga, 240Ba and the DMD board 241a arranged in the case B22, and the focus mechanism 242.

(Display unit A: Irradiation unit B: Position / attitude adjustment of projector device B2)
As shown in FIGS. 25 to 27, the upper pedestal B220 is a sheet metal member fixed to the upper wall portion B12 (see FIGS. 6 and 8) of the projector cover B1, and includes a rectangular main body portion 2200 and a main body portion 2200. The left end 2201a and the right end 2201b that are formed by bending the left and right sides downward and outward and have a step with the main body 2200 and partially extend from the rear side of the main body 2200 to the rear. And a rear end portion 2202 that extends. The main body 2200 and the rear end 2202 are provided with three connection holes 2200A for connecting the lower pedestal B221. These three connecting holes 2200 </ b> A are arranged so as not to be positioned on the same straight line in a plane (horizontal plane) along the main body 2200. Each of the left end portion 2201a and the right end portion 2201b is provided with a plurality of square holes 2201c for fixing to the lower surface of the upper wall portion B12 by screw fastening. In the present embodiment, three square holes 2201c are arranged at each of the left end portion 2201a and the right end portion 2201b, and are provided at equal intervals in the front-rear direction. The vertical and horizontal inner diameter dimensions of the square hole 2201c are larger than the screw shaft diameter of the mounting screw T (see FIG. 28) to be inserted and fastened.

  The lower pedestal B221 is a sheet metal member that substantially corresponds to the main body 2200 and the rear end 2202 of the upper pedestal B220. Three connecting screw portions 2210 are integrally formed on the lower base B221 so as to protrude upward corresponding to the three connecting holes 2200A. These three connecting screw portions 2210 are also arranged so as not to be located on the same straight line in a plane (horizontal plane) along the lower pedestal B221. The lower pedestal B 221 inserts the tip of the connecting screw portion 2210 into the connecting hole 2200A while externally fitting the coil spring 2211 to each of the connecting screw portions 2210, and sandwiches the coil spring 2211 between the main body portion 2200 and the rear end portion 2202. The nut 2213 is fastened from the upper surface side of the upper pedestal B220 to the tip of the connection screw portion 2210 via a washer 2212 while being in a state of being in a state of being connected to be suspended from the lower surface of the upper pedestal B220. Further, as shown in FIG. 23, the lower pedestal B221 is provided with a plurality of screw holes 2214 for screwing the case B22 and a plurality of screw holes 2215 for screwing the stay B 223a. The lower pedestal B221 is connected to the lower surface of the upper pedestal B220 while supporting the under cover B223 via the case B22 and the stay B223a.

  That is, as shown in FIGS. 23 and 25 to 27, the upper pedestal B220 and the lower pedestal B221 are connected to each other at three connecting portions R1, R2, and R3 so that their distances can be adjusted. Each of the connecting portions R1, R2, and R3 includes a connecting hole 2200A of the upper base B220, a connecting screw portion 2210 of the lower base B221, a coil spring 2211, a washer 2212, and a nut 2213.

  By using the upper pedestal B220 and the lower pedestal B221, the projector device B2 is attached to the upper wall portion B12 of the projector cover B1 so that the positioning and the optical axis can be adjusted.

  FIG. 28 shows an attachment form of the upper base B220 to the upper wall part B12 of the projector cover B1. The lower diagram of FIG. 28A is a diagram showing a state in which the mounting screw T is inserted and fastened into the square hole 2201c of the upper base B220, and the upper diagram of FIG. 28A is the diagram of FIG. 28A. It is sectional drawing which follows the BB 'line shown to the following figure. FIG. 28 shows the periphery of the square hole 2201c formed in the left end 2201a of the upper pedestal B220, but the periphery of the remaining square hole 2201c in the left end 2201a and the right end 2201b is the same.

  As shown in FIG. 28 (a), the mounting screw T is inserted into the square hole 2201c from below, and the mounting screw T is disposed at substantially the center of the square hole 2201c. The attachment screw T is screwed to a nut N located on the upper surface side of the upper wall portion B12 via a washer W arranged so as to follow the upper surface of the upper wall portion B12 and the lower surface of the left end portion 2201a. As a result, the left end 2201a of the upper base B220 is attached to the upper wall B12 of the projector cover B1 by screws. The right end 2201b of the upper base B220 is also attached to the upper wall B12 of the projector cover B1 by the same screwing.

  Here, the hatched portion indicated by the symbol A in FIG. 28A is a gap formed between the screw shaft of the mounting screw T and the square hole 2201c. In FIG. 28A, the screw shaft of the mounting screw T is disposed and fixed substantially at the center of the square hole 2201c. At this time, the screw shaft of the mounting screw T can be moved within the range (adjustment range) of the hatched portion indicated by the symbol A. That is, by finely adjusting the relative position of the mounting screw T to the square hole 2201c within the opening range of the square hole 2201c, the left end portion 2201a of the upper base B220 is positioned and adjusted with respect to the upper wall portion B12 of the projector cover B1. be able to. Similarly, the right end portion 2201b of the upper base B220 can be positioned and adjusted with respect to the upper wall portion B12 of the projector cover B1.

  FIG. 28B shows a state where the left end 2201a of the upper base B220 is shifted in the direction of arrow E with respect to FIG. The upper view of FIG. 28B is a cross-sectional view taken along the line D-D ′ shown in the lower view of FIG. In the state shown in FIG. 28 (b), the screw shaft of the mounting screw T is displaced relatively to the left in the opening range of the square hole 2201c, and is within the hatched portion range (adjustment range) indicated by symbol C. It is possible to move with.

  Thus, the upper base B220 is attached to the upper wall portion B12 of the projector cover B1 while being positioned and adjusted within a predetermined adjustment range that is the opening range of the square hole 2201c. That is, in the projector device B2, the mounting position with respect to the upper wall portion B12 is adjusted in the left-right direction and the front-back direction by the plurality of square holes 2201c provided in the left end portion 2201a and the right end portion 2201b of the upper base B220. As a result, the direction of light emitted from projector device B2 is easily adjusted as the reference direction so as to be perpendicular to the left-right direction and coincide with the front-rear direction.

  FIG. 29 shows a connection structure of the lower pedestal B221 with respect to the upper pedestal B220. FIG. 29 is a cross-sectional view showing a state where the lower pedestal B221 is connected to the upper pedestal B220 by the connection hole 2200A, the connection screw part 2210, the coil spring 2211, the washer 2212, and the nut 2213 in the connection part R2. In addition, although FIG. 29 shows one connection part R2, the other connection parts R1 and R3 are the same.

  The connection screw portion 2210 of the lower pedestal B221 is inserted into the connection hole 2200A from the lower surface side of the main body portion 2200 of the upper pedestal B220, and is screwed to the nut 2213 via a washer 2212 disposed on the upper surface side of the main body portion 2200. The A coil spring 2211 is externally fitted to the connecting screw portion 2210, and this coil spring 2211 is sandwiched between the lower surface of the main body 2200 and the upper surface of the lower pedestal B221 at the peripheral edge of the connecting hole 2200A. By such a coil spring 2211, the portion in the vicinity of the connecting portion R2 between the upper pedestal B220 and the lower pedestal B221 is urged in the direction away from each other (vertical direction). It is possible to prevent loosening at the joint portion.

  In such a connecting portion R2, the distance between the upper pedestal B220 and the lower pedestal B221 is changed while being biased by the coil spring 2211 by appropriately turning the nut 2213 in the tightening direction or the loosening direction. Specifically, when the nut 2213 is turned in the tightening direction, the distance between the upper pedestal B220 and the lower pedestal B221 in the connection R2 is reduced. At this time, the upper pedestal B220 is fixed to an upper wall B12 (not shown in FIG. 29). Therefore, the portion near the connecting portion R2 of the lower pedestal B221 is displaced in a direction approaching the upper pedestal B220 by appropriately tightening the nut 2213, and the height position is adjusted to a higher position. On the other hand, when the nut 2213 is turned in the loosening direction, the distance between the upper pedestal B220 and the lower pedestal B221 in the connection R2 is increased. That is, the portion near the connecting portion R2 of the lower pedestal B221 is displaced in a direction away from the upper pedestal B220 by appropriately loosening the nut 2213, and the height position is adjusted to a lower level.

  Also in the other connecting portions R1, R3, the height position of the lower pedestal B221 near the connecting portions R1, R3 can be easily adjusted by appropriately adjusting the tightening amount of the nut 2213 in the same manner as described above. Specifically, such connecting portions R1, R2, and R3 are not connected to the same straight line in the plane (horizontal plane) along the upper pedestal B220 and the lower pedestal B221. Specifically, the lines connected to each other form a triangle. Are arranged as follows. That is, since the lower pedestal B221 can finely adjust the height position by the tightening amount of the nut 2213 in each of the three connecting portions R1, R2, and R3, the posture of the lower pedestal B221 is changed in the front-rear direction, The degree of inclination in the three-dimensional space can be adjusted with respect to any of the horizontal direction and the vertical direction.

  Such posture adjustment of the lower pedestal B221 is performed while irradiating light to the screen or the like from the projector device B2 supported by the lower pedestal B221. At that time, an image is projected onto the screen or the like by the irradiation light, and the posture of the lower pedestal B221 is adjusted while confirming the image. Thereby, the optical axis direction of the light irradiated from projector apparatus B2 is adjusted so that an image is projected in an appropriate display mode on the surface of a screen or the like. That is, the optical axis direction can be adjusted in advance so that a so-called trapezoidal distortion or the like does not occur as an image display mode by adjusting the posture of the lower pedestal B221.

  As shown in FIG. 30, the adjustment in the optical axis direction and the like is performed using an adjustment PC 1000 connected to the projector apparatus B2 via the sub control board SS or the like. The projector device B2 attached to the upper wall portion B12 via the upper pedestal B220 and the lower pedestal B221 is not only adjusted in the optical axis direction but also displayed on the screen and the like during inspection at the factory. Various adjustments necessary for projecting and displaying the video are performed. The adjustment PC 1000 is temporarily connected to the projector control board B23 of the projector device B2 during the adjustment work (see FIG. 37). When the adjustment PC 1000 is operated, optical parameters relating to the projection position of the irradiation light, the focus adjustment, and the like in the projector apparatus B2 are changed by a predetermined command transmitted from the adjustment PC 1000. The projection position and the optical parameters appropriately adjusted in this way are the horizontal direction, vertical direction and focus position adjustment value data (horizontal direction position A to E adjustment value, vertical direction position A to E adjustment value, focus position A. To E adjustment value) are stored in the EEPROM 231 of the projector control board B23 (see FIG. 106). When the adjustment value data of the horizontal direction, the vertical direction, and the focus position stored in the EEPROM 231 is not supplied with power to the projector device B2 for transportation after factory shipment, and the gaming machine 1 is installed in the game hall But it can be used as is. Such horizontal position adjustment data and vertical adjustment data are acquired to control the lens shift mechanism of the lens unit B 21, and focus position adjustment value data is acquired to control the focus mechanism 242. . Note that the horizontal position A to E adjustment value, the vertical position A to E adjustment value, the focus position A to E adjustment value, the horizontal position A to E offset, the vertical position A to E offset, and the focus position described later. As for “A to E” of the A to E offset and the focus drift correction values A to E, for example, “A” is the projection surface of the fixed screen mechanism D, “B” is the projection surface E11a of the front screen member E11, and “C”. Corresponds to the adjustment value data corresponding to the projection surface F1a of the reel screen mechanism F1, and “D” and “E” are reserved in consideration of future expandability (when the number of projection surfaces increases). .

  As is apparent from the above description with reference to FIGS. 28 to 30, the projector device B <b> 2 is positioned in the left-right direction and the front-rear direction mainly according to the mounting position of the upper base B <b> 220 with respect to the upper wall B <b> 12, The optical axis direction is adjusted according to the posture of the side base B221 in the three-dimensional space.

  In the present embodiment, the connecting portions for connecting the upper pedestal B220 and the lower pedestal B221 to each other are provided at three locations. However, if the condition that at least three locations are not on the same straight line is satisfied, four locations are provided. You may make it provide a connection part above. Further, in this embodiment, the connection hole 2200A is provided in the upper pedestal B220 and the connection screw part 2210 is provided in the lower pedestal B221. However, these connection holes and connection screw parts may be provided upside down. The connecting screw portion is not limited to the one integrally formed with the pedestal as in the present embodiment, but may be any one that can be fixed to one pedestal. For example, the connecting screw portion may be a bolt that penetrates and is fixed through the lower pedestal.

(Display unit A: Irradiation unit B: Intake / exhaust structure of projector device B2)
As shown in FIGS. 31 to 33, the case B22 of the projector apparatus B2 is provided with three intake ports B22A, B22B, and B22C and two exhaust ports B22D and B22E. Of the three intake ports B22A, B22B, B22C, two intake ports B22A, B22B are provided with intake fans 244A, 244B, while one intake port B22C is not provided with an intake fan. Of the two exhaust ports B22D and B22E, one exhaust port B22D is provided with an exhaust fan 245, while the other exhaust port B22E is not provided with an exhaust fan.

  At the air inlet B22A, air is forcibly taken into the case B22 by the air intake fan 244A, and this air flow passes through the heat sink 243R as the air flow path P1, thereby depriving the heat sink 243R of heat. Thereafter, the air flow path P1 linearly flows from the heat sink 243R to the exhaust port B22E, and is naturally discharged (heat exhausted) from the exhaust port B22E to the outside of the case B22.

  Also at the air inlet B22B, air is forcibly taken into the case B22 by the air intake fan 244B. The air flow passes through the plurality of heat sinks 243D, 243B, and 243G while passing through a part of the empty space S as the air flow path P2, thereby depriving the heat sinks 243D, 243B, and 243G of heat. Thereafter, the air flow path P2 is drawn into the exhaust fan 245 so as to bend toward the exhaust port B22D, and is forcibly exhausted (exhaust heat) from the exhaust port B22D to the outside of the case B22.

  At the air inlet B22C, air is forcibly taken into the case B22 mainly by the drawing force of the exhaust fan 245. This air flow takes heat from the plurality of heat sinks 243B and 243G by passing mainly through the heat sinks 243B and 243G while passing through a considerable portion of the empty space S as the air flow path P3. Thereafter, the air flow path P3 is also drawn into the exhaust fan 245 so as to bend toward the exhaust port B22D, and is forcedly discharged from the exhaust port B22D to the outside of the case B22 while joining the air flow path P2. (Exhaust heat). The intake fans 244A and 244B and the exhaust fan 245 function as a cooling device for the projector apparatus B2.

  In the present embodiment, as described above, the LED light sources 240G and 240B exhibit relatively high heat generation characteristics, while the LED light sources 240R and DMD 241 exhibit relatively low heat generation characteristics. LED substrates 240Ga and 240Ba on which LED light sources 240G and 240B having high heat generation characteristics are mounted are in thermal contact with heat sinks 243G and 243B through which the plurality of air flow paths P2 and P3 pass.

  Here, the plurality of air flow paths P2 and P3 join together at one exhaust port B22D while flowing in from different intake ports B22B and B22C, and flow out from the exhaust port B22D using the exhaust port B22D as a common vent. It has become. As a result, the plurality of air flow paths P2 and P3 are forced to be discharged while being merged, so that a smooth flow can be obtained and the heat sinks 243G and 243B can be efficiently deprived of heat and cooled. .

  Further, since the plurality of air flow paths P2 and P3 are efficiently and forcibly exhausted by the exhaust fan 245, it is possible to effectively collect heat from the plurality of optical elements such as the LED light sources 240G and 240B and the DMD 241 in the projector device B2. Therefore, overheating of optical components such as lenses can be prevented.

  Furthermore, since three more heat sinks 243D, 243B, 243G are cooled by two air flow paths P2, P3 leading to one exhaust port B22D, they are provided corresponding to these heat sinks 243D, 243B, 243G. A plurality of optical elements such as the DMD 241 and the LED light sources 240B and 240G can be cooled more efficiently.

  In the present embodiment, the two air flow paths P2 and P3 are merged at one exhaust port 245. For example, three or more air flow paths P1 are merged at the exhaust port 245. These air flow paths may be collectively discharged from one exhaust port.

Above the hopper mechanism HP, a medal replenishment mechanism MH (corresponding to a replenishment port) for replenishing metal medals from the outside is provided, and medals are dropped from the medal replenishment mechanism MH to the hopper mechanism HP. A scaler substrate SK for connecting the projector device B2, the sub liquid crystal display device DD19, and the touch panel DD19T to the sub control substrate SS is provided above the medal supply mechanism MH.

  In the present embodiment, the sheet metal BK is not in contact with the sub control board SS. The sheet metal BK may be directly attached to the bottom of the sub control board SS. Further, the thin sub-relay substrate SN that is detachably attached to the lower surface of the intermediate support plate G1 and the thin sub-control substrate SS that is detachably attached to the back wall G3 of the cabinet G are shown in side view. It is arranged in a state that the L-shape is turned upside down.

  According to the above configuration, since the sheet metal BK is provided between the sub control board SS and the hopper mechanism HP, even if a medal is dropped on the hopper mechanism HP and jumps out to the sub control board SS side, It is possible to prevent the medal from physically contacting the sub control board SS. Further, since the sheet metal BK is provided between the sub-control board SS and the hopper mechanism HP, the influence of radiation (electromagnetic field) due to contact between metal medals in the hopper mechanism HP can be prevented by the sheet metal BK. Further, since the sub control board SS is provided on the back side of the lower space of the cabinet G and is sandwiched between the back wall G3 and the sheet metal BK, the sub control board SS is removed from the cabinet G unless the sheet metal BK is removed. I can't. This enhances the security for the sub control board SS.

The claw portions G5121a and G5121b are locked bars inserted into the openings G5122a and G5122b provided in the tube G5122 by sliding up and down in the tube G5122 along with the sliding of the locking plate G5121. Locking with respect to G511a and G511b, or locking is released. The locking plate G5121 has a spring that is biased upward.

  The claw portions G5121a and G5121b are locked with respect to the locked rods G511a and G511b when the locking plate G5121 is at a height position for locking the lower door mechanism DD, while the locking plate G5121 is locked with the lower door mechanism DD. It is set so that the locking to the locked rods G511a and G511b is released when it is lowered from the height position where the lock is released to the height position where the lock is released. Further, the claw portions G5121a and G5121b have tip surfaces inclined obliquely downward, and are pushed down by contact with the locked rods G511a and G511b.

  Although not shown in the drawing, the locking portion G512 has a lowering portion in the middle. The pulling portion enables the locking plate G5121 to be pulled downward as a key is inserted into the cylinder lock G513 and rotated. As a result, when the locking plate G5121 is lowered, the locking between the claw portions G5121a and G5121b and the locked rods G511a and G511b can be released. The lower door mechanism DD is provided with a door relay board DS for connecting electronic components and the like on the door side and the cabinet G side.

(Upper door mechanism DU: Upper door lock mechanism G52)
As shown in FIG. 35, the upper door lock mechanism G52 includes a locked portion G521 fixed to the right end portion of the back wall of the upper door mechanism DU and a lock portion G522 fixed to the right end portion of the cabinet G. Have.

  The locked portion G521 has two rods to be locked G521a and G521b formed on both ends of a concave frame G521c at the upper and lower portions.

  The locking portion G522 has a long cylinder G5222 and a long locking plate G5221 that is slidably disposed in the vertical direction in the cylinder G5222.

  The locking plate G5221 has claw-shaped claw portions G5221a and G5221b that are locked to the locked rods G521a and G521b. The claw portions G5221a and G5221b are locked rods inserted into the openings G5222a and G5222b provided in the tube G5222 by sliding up and down in the tube G5222 along with the sliding of the locking plate G5221. The locking is performed with respect to G521a and G521b, and the locking is released.

  The claw portions G5221a and G5221b are locked to the locked rods G521a and G521b when the locking plate G5221 is at a height position where the upper door mechanism DU is locked, while the locking plate G5221 is locked to the upper door mechanism DU. Is set so that the locking to the locked rods G521a and G521b is released when the lock is lowered from the height position where the lock is released to the height position where the lock is released. Further, the claw portions G5221a and G5221b are inclined at the tip end surfaces in a diagonally downward direction, and are pushed down by contact with the locked rods G521a and G521b.

  An opening (not shown) is formed in the cylinder G5222 of the locking portion G522 below the upper door mechanism DU, and a protrusion (not shown) provided on the locking plate G5221 passes through the opening. It protrudes to the inside of the cabinet G. By pulling the projection downward, the locking plate G5221 is lowered, and accordingly, the locking between the claw portions G5221a and G5221b and the locked rods G521a and G521b can be released.

  Here, the protruding portion is slid upward, and is disposed so as to contact the upper portion of the lower door mechanism DD when the locking plate G5221 is in a height position for locking the upper door mechanism DU.

  According to the above configuration, in a state where the lower door mechanism DD is closed, the upper portion of the lower door mechanism DD physically interferes with the protruding portion, thereby preventing the locking plate G5221 from sliding, and the claw portion G5221a. , G5221b and the locked rods G521a and G521b cannot be released, and the upper door mechanism DU can be locked so that it cannot be opened.

  On the other hand, when the lower door mechanism DD is open, physical interference with the protrusions on the upper portion of the lower door mechanism DD is released, so that the locking plate G5221 can slide in the cylinder G5222 and the claw portion G5221a. , G5221b can be unlocked from the locked bars G521a and G521b, and the upper door mechanism DU can be unlocked from the cabinet G.

  Thereby, in order to unlock the upper door mechanism DU, the lower door mechanism DD needs to be unlocked first by the lower door lock mechanism G51. That is, in order to open the upper door mechanism DU, the lock release operation is performed on the lower door lock mechanism G51, and after the lower door mechanism DD is opened, the lock release operation on the upper door lock mechanism G52 is required. Security for the upper space of the cabinet G can be increased. In addition, the upper space of the cabinet G can be more secure than the lower space of the cabinet G, and the lower space of the cabinet G can be accessed more smoothly than the upper space of the cabinet G. Can be a place.

  In order to unlock the lower door mechanism DD, it is necessary to unlock the cylinder lock G513 with a key. The manager of the gaming machine 1 has an advantage that the key is easy to manage because it is compact and suitable for carrying.

  Further, by the sliding of the locking plate G5221, the claw portions G5221a and G5221b are hooked on the locked bars G521a and G521b, or the hooks are released. Accordingly, the upper space of the cabinet G of the upper door mechanism DU can be locked in conjunction with the sliding of the locking plate G5221.

  Further, the upper door lock mechanism G52 is provided at the end opposite to the end portion that is pivotally supported, and is disposed on the side where the upper door mechanism DU is opened and closed, so that the upper door lock mechanism G52 is unlocked. Therefore, it is not necessary to open the lower door mechanism DD greatly. Thereby, in order to unlock the upper door mechanism DU, the lower space of the cabinet G is not unnecessarily exposed to the outside, and security can be improved.

  In the present embodiment, a one-way hinge that applies a predetermined torque in the direction in which the lower door mechanism DD is closed is employed between the lower door mechanism DD and the cabinet G. Thereby, when closing the lower door mechanism DD, torque is applied and the lower door mechanism DD can be quietly closed with respect to the cabinet G without applying a sudden load. Thereby, it is possible to prevent a sudden load from being applied to the protrusion B131 physically interfered by the lower door mechanism DD.

(Relationship between lower door DD1, reel unit RU, and main control board MS)
As shown in FIG. 36, the lower door mechanism DD of the gaming machine 1 includes a lower door DD1, a reel unit RU, and a main control board MS.

  The lower door DD1 is provided so as to be openable and closable with respect to the cabinet G (corresponding to a casing). As shown in FIG. 36, the reel unit RU is detachably provided on the back side of the lower door DD1 (inside the cabinet G (lower space side)). In addition to the reels RL, RC, RR, the reel unit RU is provided with a reel drive substrate RD for controlling the reel motor. The main control board MS is detachably provided on the back side of the reel unit RU (inside the cabinet G (lower space side)).

  The main control board MS rotates the reels RL, RC, RR of the reel unit RU based on command signals output from the start lever DD6 and stop buttons DD7L, DD7C, DD7R (see FIG. 3). By stopping, the symbols arranged on the reels RL, RC, RR are stopped and displayed.

  By integrating the lower door DD1, the reel unit RU, and the main control board MS according to the positional relationship of the lower door DD1, the reel unit RU, and the main control board MS as described above, the gaming machine 1 Can be easily performed when assembling, exchanging and disassembling parts.

  Further, the main control board MS is an important configuration for controlling the game, and measures to prevent unauthorized removal are necessary. However, since the main control board MS is integrated with the reel unit RU, the main control board MS is removed. Can be difficult.

  The main control board MS is provided on the back surface of the reel unit RU provided on the inner side of the lower door DD1. Accordingly, the main control board MS can be disposed on the back side of the cabinet G far from the lower door DD1 by the thickness of the lower door DD1 and the reel unit RU. For this reason, a physical distance can be ensured between the lower door DD1 and the main control board MS, and even if it is illegally intruded through the gap of the lower door DD1, it reaches the main control board MS. It becomes difficult to improve security.

  Further, since the lower door DD1, the reel unit RU, and the main control board MS are integrated, when changing the specifications of the gaming machine 1, the exterior of the lower door DD1 is changed, and the reel design of the reel unit RU is changed. Changes and game contents can be changed together.

Description of these known components is omitted.

  A general harness and an optical fiber cable are used for connection of each board | substrate. For example, the main control board MS is connected to these boards and the like via the harness H so as to output a control signal in one direction to each of the reel drive board RD and the 7-segment display 30. The reel drive substrate RD is connected to the door relay substrate DS via the first optical fiber cable FC1 so as to optically transmit various signals in one direction to the door relay substrate DS. The door relay board DS is connected to the main control board MS via the second optical fiber cable FC2 so as to optically transmit various signals in one direction to the main control board MS. As a result, the main control board MS, the reel drive board RD, and the door relay board DS are loop-connected through the harness H and the optical fiber cables FC1 and FC2 so as to transmit a command or the like only in one direction. The sub relay board SN is connected to a security IC 306 (not shown) of the main control board MS via an optical fiber cable (not shown), and the external concentrated terminal board 31 is connected to a security IC 307 (not shown) of the main control board MS. ) Is connected through. The security ICs 306 and 307 of the main control board MS conceal communication data by, for example, encrypting a plain text transmission command by the AES method.

  The main control board MS is a board for controlling the main game operation of the gaming machine 1. As shown in FIG. 38, the main control board MS has a main CPU 300, a main RAM 301, a main ROM 302, a clock pulse generation circuit 303, a frequency divider 304, a master I / O communication LSI 305, and security ICs 306 and 307. For example, the main CPU 300 transmits a command for controlling the reel rotation operation and the medal payout operation to the reel drive board RD through the I / O communication LSI 305. Further, the main CPU 300 optically receives signals from various switches (50 to 56) connected to the door relay board DS through the I / O communication LSI 305 and performs predetermined processing based on these signals. . Specific processing of the main control board MS (main CPU 300) will be described later.

  The sub-control board SS is a board for mainly controlling effects accompanying the game of the gaming machine 1. The sub control board SS is connected to the sub relay board SN via a connector (BtoB: board-to-board), and the sub relay board SN and the scaler board SK are connected to each other via a harness H. Various signals are exchanged in both directions.

  As shown in FIG. 39, the sub control board SS has a sub CPU 400, an SRAM (Static Random Access Memory) 401 having a backup function, and a real time clock (RTC: Real Time Clock) 402 which is a date and time measuring circuit. As possible expansion cards, a graphic board 40, a sub RAM board 41, and a sub ROM board 42 are mounted by bus connection. The graphic board 40 includes a GPU (Graphics Processing Unit) 440 and a VRAM (Video Memory) 441. For example, the sub CPU 400 transmits a signal for displacing the projection surfaces E11a and F1a to the front screen drive mechanism E2 and the reel screen drive mechanism F2 through the sub relay substrate SN and the screen drive control substrate CS (see FIG. 42). . Further, the sub CPU 400 transmits a video signal for causing the projector device B2, the sub liquid crystal display device DD19, and the like to display an image to the projector control board B23 and the sub liquid crystal I / F board SL through the scaler board SK (FIG. 43). reference). Specific processing of such a sub control board SS (sub CPU 400) will be described later.

  The reel drive substrate RD is a substrate for controlling the rotation operation of the reels RL, RC, RR in the reel unit RU and controlling the medal payout operation by the hopper mechanism HP. As shown in FIG. 40, the reel drive board RD includes an I / O communication LSI 310, a reel motor driver 311, and a hopper motor driver 312 that are slaves to the I / O communication LSI 305 that is the master of the main control board MS. For example, the I / O communication LSI 305 receives a payout signal from the hopper mechanism HP, a detection signal from the medal replenishment mechanism switch MHS that detects the drop of the medal into the hopper mechanism HP, a signal from the reel unit RU that indicates the reel rotation state, and the like. Are converted into optical signals according to a predetermined optical communication system, and these optical signals are transmitted to the main control board MS via the first optical fiber cable FC1 and the door relay board DS. Further, the I / O communication LSI 305 inputs control signals for instructing start / stop of reel rotation, payout of medals, etc. from the main control board MS via the harness H, and receives control signals corresponding to these control signals. Then, the data is output to the reel unit RU and the hopper mechanism HP through the reel motor driver 311 and the hopper motor driver 312. As described above, the main control board MS outputs a control signal based on an electrical signal, and the input to the main control board MS is performed by communication via the optical fiber cables FC1 and FC2. This is because there is a problem of quick response with the hopper mechanism HP (transmission time problem due to command transmission). In short, the main control board M and the reel drive board RD are not connected via an optical fiber cable so as not to cause a significant shift in the symbol stop position due to a delay when the reel is stopped after the stop button is pressed, for example. It is like that.

  The door relay board DS relays various signals in one direction from the reel drive board RD and various switches (50 to 56) provided on the door side to the main control board MS provided on the cabinet G side. It is a substrate. As shown in FIG. 41, the door relay board DS includes an I / O communication LSI 500 serving as a slave and an external input driver 501 with respect to the I / O communication LSI 305 serving as a master of the main control board MS. For example, the I / O communication LSI 500 receives signals from various switches and the like (50 to 56) through the external input driver 501, converts them into optical signals according to a predetermined optical communication method, and converts these optical signals. The data is transmitted to the main control board MS via the second optical fiber cable FC2. The I / O communication LSI 500 also receives a signal from the reel driver board RD, converts it to an optical signal according to a predetermined optical communication system, and converts this optical signal to the main control board via the second optical fiber cable FC2. Send to MS.

  The sub-relay board SN is a board for mainly relaying commands from the main control board MS to the sub-control board SS and relaying various signals between the production mechanism and the sub-control board SS. . As shown in FIG. 42, the sub relay board SN includes a security IC 600, a sound IC 601, a digital amplifier 602, and an I2C controller 603. For example, the sub relay board SN transmits the video signal from the sub control board SS to the scaler board SK as a bypass signal, and transmits the screen drive signal from the sub control board SS via the I2C controller 603 to the screen drive control board CS. And the detection signal of the door monitoring switch 64 is exchanged with the door monitoring unit 63 for 24 hours. The security IC 600 receives a security command (such as various commands from the encrypted main control board MS) from the main control board MS and converts the security command into plain text (decrypts the encrypted command). Transmit to the sub control board SS. The sound IC 601 receives an effect sound signal from the sub-control board SS, and transmits a signal corresponding to the sound signal to the speaker group 62 through the digital amplifier 602. The I2C controller 603 receives a lighting signal for production from the sub control board SS, transmits a signal corresponding to the lighting signal to the LED board 60, and between the sub control board SS and the screen drive control board CS.

  The scaler substrate SK mainly receives a video signal for production from the sub control substrate SS, divides the video signal, generates video signals corresponding to a plurality of video display numbers, and outputs these video signals to the projector device B2. And a substrate for transmitting to the sub liquid crystal display device DD19. As shown in FIG. 43, the scaler substrate SK includes an MCU (Micro Control Unit) (control LSI) 700, a multi-output scaler LSI (also referred to as resolution conversion LSI) 710, a V-by-one (registered trademark) HS transmitter 711, And SDRAM (DDR SDRAM / DDR2 SDRAM / DDR3 SDRAM, etc.) 712. The MCU 700 is connected to the sub-relay board SN and the multi-output scaler LSI 710, and to the sub liquid crystal I / F board SL and the projector control board B23. The multi-output scaler LSI 710 is connected to the sub control board SS as an input source, and is also connected to the MCU 700, the V-by-oneHS transmitter 711, the SDRAM 712, and the projector control board B23. The V-by-one HS transmitter 711 is connected to the sub liquid crystal I / F substrate SL as an output destination.

  As shown in FIG. 44, the multi-output scaler LSI 710 constitutes an MCU interface (for example, PCI Express) 800 and SDRAM interface (for example, PCI Express) 820 and a resolution conversion output block connected to the MCU 700 and SDRAM 712 (not shown). , Multiple select areas A to D801 to 804, LVDS (Low Voltage Differential Signaling) (1), (2) 811 and 812 as a differential interface, LVTTL (Low Voltage Transistor Transistor Transistor LV) as an input / output interface (1), (2) 813, 814, and DSF (Dub) constituting the video division block Having e Scaling Filter) (α) 821, DSF (β) 822.

  The multi-output scaler LSI 710 divides and converts the resolution of, for example, an LVDS signal as a video signal and outputs it. Specifically, the multi-output scaler LSI 710 divides a pair of LVDS signals (LDVS Dual: InPutA, InPutB) by differential transmission from the sub control board SS into two by DSF (α) 821 and DSF (β) 822, Further, each of the four select areas A to D801 to 804 is converted into a predetermined resolution. Thereafter, the multi-output scaler LSI 710 mainly outputs an LVDS signal for projector display (single signals of LVDS1 and LVDS2) through LVDS (1), (2) 811 and 812, and LVTTL (1), (2) 813. , 814, LVTTL signals (LVTTL1 and LVTTL2 RGB signals) for sub liquid crystal display are output. The LVDS signal output from the multi-output scaler LSI 710 is transmitted to the projector control board B23 directly or through the MCU 700, and the LVTTL signal is transmitted to the sub liquid crystal I / F board SL through the V-by-one HS transmitter 711 or the MCU 700. Is done. Specific processing of such a scaler substrate SK (MCU 700, multi-output scaler LSI 710) will be described later.

  The sub liquid crystal I / F substrate SL mainly relays the video signal (LVTTL signal) from the scaler substrate SK to the sub liquid crystal display device DD19, and between the sub control substrate SS and the touch panel DD19T via the scaler substrate SK. It is a substrate for relaying various signals. As shown in FIG. 45, the sub liquid crystal I / F substrate SL includes an MCU 900, a V-by-one HS receiver 901, a liquid crystal driver IC 902, and an LED driver IC 903. For example, the sub liquid crystal I / F substrate SL receives the video signal from the scaler substrate SK by the V-by-one HS receiver 901 and the MCU 900, and the liquid crystal driver IC 902 receives a control signal for driving the liquid crystal based on the video signal. The LED driver IC 903 transmits a control signal for driving the liquid crystal display backlight to the sub liquid crystal display device DD19. Thereby, in the sub liquid crystal display device DD19, an image is displayed at a predetermined resolution based on the image signal. Further, the MCU 900 receives an operation signal from the touch panel DD19T, and transmits a signal corresponding to the operation signal to the sub-control board SS via the scaler board SK. Thereby, the sub CPU 400 of the sub control board SS recognizes the input operation corresponding to the operation signal from the touch panel DD19T. Although not particularly illustrated, the sub liquid crystal display device DD19 incorporates a temperature sensor such as a thermistor, and a temperature detection signal from the temperature sensor is transmitted to the sub liquid crystal I / F substrate SL, so that the sub liquid crystal is displayed. The MCU 900 of the I / F board SL can recognize the temperature during operation. Specific processing of the sub liquid crystal I / F substrate SL (MCU 900) will be described later. Specific processing of the projector control board B23 (control LSI 230) shown in FIG. 21 will also be described later.

(Video split display pattern)
In the present embodiment, the sub-control board SS and the sub-control board SS are formed so as to form a divided display pattern as shown in FIG. 46 when the sub liquid crystal display device DD19 displays an effect image or when performing optical adjustment of the projector device B2. The scaler substrate SK performs signal processing to display an image. That is, as shown in FIG. 46, the sub-control board SS has video data for projector display (data block indicated by “α” with a resolution of 1280 × 800) and video data for sub-liquid crystal display (with a resolution of 480 × 800). LVDS dual-in signal composed of one synthesized signal is transmitted to the scaler substrate SK.

  The scaler substrate SK generates two video data α, β from the LVDS dual-in signal by the DSF (α), (β) 821, 822 of the multi-output scaler LSI 710, and SDRAM 712 by buffering these video data α, β. Temporarily store. The video data α and β are developed in the memory space of the SDRAM 712 in an array image as shown on the left side of FIG.

  Thereafter, the MCU 700 of the scaler substrate SK converts the video data α read from the SDRAM 712 into an LVDS1 signal for display on the projector (video signal indicated by “A” with a resolution of 1280 × 800) through the select area A801 and LVDS (1) 811. Then, the LVDS1 signal A is transmitted to the projector control board B23. At the same time, the MCU 700 converts the video data β read from the SDRAM 712 into an LVTTL1 signal (video signal indicated by “C” of resolution 480 × 800) for sub liquid crystal display through the select area C803 and LVTTL (1) 813. The LVTTL1 signal C is transmitted to the sub liquid crystal I / F substrate SL through the V-by-one HS transmitter 711. In this case, the LVDS1 signal A and the LVTTL1 signal C are transmitted at the resolution specified by the sub control board SS without converting the resolution. Accordingly, the projector device B2 can project an image with a resolution corresponding to the number of 1280 × 800 pixels, and the sub liquid crystal display device DD19 can display an image on the screen with a resolution corresponding to the number of 480 × 800 pixels.

  It should be noted that as the split display pattern, variations such as those shown in FIGS. 47 to 52 can be realized according to the display mode change such as the number of screens (display devices) for displaying video and the enlargement ratio change for resolution. ing.

(Modification 1)
For example, as shown in FIG. 47, the sub-control board SS has video data for projector display (data block indicated by “α” with a resolution of 1280 × 800) and video data for sub-liquid crystal display (with a resolution of 1024 × 768). LVDS dual-in signal composed of one synthesized signal is transmitted to the scaler substrate SK.

  At this time, the scaler substrate SK inputs the two video data α, β divided by the DSF (α), (β) 821, 822 based on the received LVDS dual-in signal as shown on the left side of FIG. The array image of pattern 1 or input pattern 2 is expanded in the memory space of SDRAM 712.

  If the enlargement ratio change (resolution change) is not set, the MCU 700 of the scaler substrate SK converts the video data α read from the SDRAM 712 into the select areas A, B 801, 802 and the LVDS as shown in the upper right of FIG. (1), (2) 811 and 812 are converted into a projector display LVDS1 + 2 signal (video signal indicated by “A + B” with a resolution of 1280 × 800), and this LVDS1 + 2 signal A + B is transmitted to the projector control board. At the same time, the MCU 700 reads the video data β read from the SDRAM 712 through the select areas C, D803, 804 and the LVTTL (1), (2) 813, 814, and the LVTTL1 + 2 signal for sub liquid crystal display (“C + D of resolution 1024 × 768” The LVTTL1 + 2 signal C + D is transmitted to the sub liquid crystal I / F substrate SL through the V-by-one HS transmitter 711. In this case, the LVDS1 + 2 signal A + B and the LVTTL1 signal C + D are transmitted at the resolution specified by the sub control board SS without converting the resolution. Accordingly, the projector device (for example, abbreviation of WXGA: Wide-XGA) projects an image with a resolution equivalent to the number of 1280 × 800 pixels, and the sub display device DD20 is changed to a sub liquid crystal display device (for example, XGA: eXtended Graphics Array). In the case where the image is provided, the video can be displayed on the screen with a resolution equivalent to the number of 1024 × 768 pixels.

  On the other hand, when the enlargement ratio change (resolution change) is set, the MCU 700 of the scaler substrate SK converts the video data α read from the SDRAM 712 into the select areas A, B 801, 802, and the like as shown in the lower right of FIG. Through LVDS (1), (2) 811 and 812, the LVDS 1 + 2 signal A + B having a resolution of 1920 × 1080, for example, corresponding to the setting value for changing the magnification rate is converted, and this LVDS1 + 2 signal A + B is transmitted to the projector control board B23. At the same time, the MCU 700 reads the video data β read from the SDRAM 712 through the select areas C, D803, 804 and the LVTTL (1), (2) 813, 814, for example, resolution 1280 × 800 according to the set value of the enlargement ratio change. The LVTTL1 + 2 signal C + D is converted to the LVTTL1 + 2 signal C + D, and the LVTTL1 + 2 signal C + D is transmitted to the sub liquid crystal I / F substrate SL through the V-by-one HS transmitter 711. In this case, the LVDS1 + 2 signal A + B and the LVTTL1 signal C + D are transmitted at a resolution different from that specified by the sub-control board SS, and the projector apparatus and the sub liquid crystal display apparatus have an appropriate resolution suitable for the display characteristics unique to each apparatus. Video can be displayed.

(Modification 2)
Also, for example, as shown in FIG. 48, the sub control board SS has video data for projector display (data block indicated by “α” of resolution 1280 × 800) and two video data (resolution) for sub liquid crystal display. The data block indicated by “β-1” of 800 × 480 and the data block indicated by “β-2” having a resolution of 800 × 480) are combined to generate an LVDS dual-in signal consisting of one combined signal as the scaler substrate SK. Send to.

  At this time, the scaler substrate SK generates three pieces of video data α, β-1, and β-2 divided by DSF (α) and (β) 821 and 822 based on the received LVDS dual-in signal as shown in FIG. The array image of any of the input patterns 1 to 3 as shown on the left side is expanded in the memory space of the SDRAM 712.

  If the enlargement ratio change (resolution change) is not set, the MCU 700 of the scaler substrate SK converts the video data α read from the SDRAM 712 into the select areas A, B 801, 802 and the LVDS as shown in the upper right of FIG. (1), (2) 811 and 812 are converted into a projector display LVDS1 + 2 signal (video signal indicated by “A + B” with a resolution of 1280 × 800), and this LVDS1 + 2 signal A + B is transmitted to the projector control board B23. At the same time, the MCU 700 transmits the two video data β-1, β-2 read from the SDRAM 712 through the select areas C, D803, 804 and the LVTTL (1), (2) 813, 814 to the LVTTL1 signal for sub liquid crystal display. And the LVTTL2 signal (video signals indicated by “C” and “D” having a resolution of 800 × 480), and the LVTTL1 signal C and the LVTTL2 signal D are transmitted through the V-by-one HS transmitter 711 to the sub liquid crystal I / F board SL. Send to. In this case, the LVDS1 + 2 signal A + B, and the LVTTL1 signal C and the LVTTL2 signal D are transmitted at the resolution specified by the sub control board SS without converting the resolution. As a result, the projector device (for example, FHD: Full-HD) projects an image with a resolution equivalent to the number of 1280 × 800 pixels, and is different from the sub liquid crystal display device DD19 as a sub liquid crystal display device. When a sub liquid crystal display device (for example, WXGA) is provided, an image can be displayed on each screen with a resolution equivalent to 800 × 480 pixels.

  On the other hand, when the enlargement ratio change (resolution change) is set, the MCU 700 of the scaler substrate SK converts the video data α read from the SDRAM 712 into the select areas A, B 801, 802, and the like as shown in the lower right of FIG. Through LVDS (1), (2) 811 and 812, the LVDS 1 + 2 signal A + B having a resolution of 1920 × 1080, for example, corresponding to the setting value for changing the magnification rate is converted, and this LVDS1 + 2 signal A + B is transmitted to the projector control board B23. At the same time, the MCU 700 sets the two video data β-1, β-2 read from the SDRAM 712 through the select areas C, D803, 804 and the LVTTL (1), (2) 813, 814. For example, the LVTTL1 signal C and the LVTTL2 signal D having a resolution of 1280 × 800 are converted into the LVTTL1 signal C and the LVTTL2 signal D, and the LVTTL1 signal C and the LVTTL2 signal D are transmitted to the sub liquid crystal I / F board SL through the V-by-one HS transmitter 711. . In this case, the LVDS1 signal A + B and the LVTTL1 signal C and the LVTTL2 signal D are transmitted at a resolution different from that specified by the sub control board SS, and the projector device (for example, FHD) and the two sub liquid crystal display devices (for example, WXGA) are transmitted. ), It is possible to appropriately display an image with a resolution suitable for display characteristics unique to each device.

(Modification 3)
Also, for example, as shown in FIG. 49, the sub control board SS includes two video data for display on the projector (data blocks indicated by “α-1” and “α-2” having a resolution of 800 × 480) and a sub-control board SS. By combining two video data for liquid crystal display (data blocks indicated by “β-1” and “β-2” with a resolution of 800 × 480), a LVDS dual-in signal composed of one composite signal is scaler substrate.

  At this time, the scaler substrate SK has four video data α-1, α-2, β-1, β− divided by DSF (α), (β) 821, 822 based on the received LVDS dual-in signal. 2 is expanded in the memory space of the SDRAM 712 with any array image of the input patterns 1 to 3 as shown on the left side of FIG.

  Then, the MCU 700 of the scaler substrate SK selects two pieces of video data α-1 and α-2 read from the SDRAM 712 as shown in the upper right of FIG. 49 if the enlargement ratio change (resolution change) is not set. Through the areas A, B801, 802 and LVDS (1), (2) 811, 812, converted into LVDS1 signals and LVDS2 signals (video signals indicated by “A” and “B” with a resolution of 800 × 480), These LVDS1 signal A and LVDS2 signal B are transmitted to the projector control board B23. At the same time, the MCU 700 transmits the two video data β-1, β-2 read from the SDRAM 712 through the select areas C, D803, 804 and the LVTTL (1), (2) 813, 814 to the LVTTL1 signal for sub liquid crystal display. And the LVTTL2 signal (video signals indicated by “C” and “D” having a resolution of 800 × 480), and the LVTTL1 signal C and the LVTTL2 signal D are transmitted through the V-by-one HS transmitter 711 to the sub liquid crystal I / F board SL. Send to. In this case, the LVDS1 signal A and the LVDS2 signal B, and the LVTTL1 signal C and the LVTTL2 signal D are transmitted at the resolution specified by the sub control board SS without converting the resolution. Accordingly, the projector device projects an image with a resolution equivalent to the number of 800 × 480 pixels, and when the sub liquid crystal device includes the sub liquid crystal display device DD19 and two separate display devices, the projector device is 800 ×. Images can be displayed on each screen with a resolution equivalent to 480 pixels.

  On the other hand, when the magnification change (resolution change) is set, the MCU 700 of the scaler substrate SK receives two pieces of video data α-1 and α-2 read from the SDRAM 712 as shown in the lower right of FIG. Through select areas A, B 801, 802 and LVDS (1), (2) 811, 812, for example, LVDS1 signal A and LVDS2 signal B having a resolution of 1280 × 720 according to the setting value for changing the enlargement ratio are converted into LVDS1 The signal A and the LVDS2 signal B are transmitted to the projector control board B23. At the same time, the MCU 700 sets the two video data β-1, β-2 read from the SDRAM 712 through the select areas C, D803, 804 and the LVTTL (1), (2) 813, 814. Is converted into LVTTL1 signal C and LVTTL2 signal D having a resolution of 1024 × 768, for example, and these LVTTL1 signal C and LVTTL2 signal D are transmitted to sub liquid crystal I / F board SL through V-by-one HS transmitter 711. . In this case, the LVDS1 signal A and the LVDS2 signal B, and the LVTTL1 signal C and the LVTTL2 signal D are transmitted at a resolution different from that specified by the sub control board SS. In the projector device and the three sub liquid crystal display devices, An image can be appropriately displayed at a resolution suitable for display characteristics unique to the apparatus.

In some cases, a plurality of LVDS single-in signals corresponding to the respective data blocks are continuously transmitted to the scaler substrate SK. Even in such a case, the signal processing similar to the above-described divided display pattern can be output separately to the LVDS signal and LVTTL signal indicating a predetermined resolution. It is possible to display an image appropriately at a resolution suitable for the display characteristics. In the present embodiment and its modifications 1 to 6, three types of resolutions, FHD, WXGA, and XGA, are exemplified. However, the present invention is not limited to these. Array) A higher-definition video may be displayed by using a display device that supports resolutions such as 2K and 4K.

For example, the scaler board may generate and output a video signal for partial screen display and a video signal for partial screen display from one video data. The scaler board may generate and output a left-eye video signal and a right-eye video signal for 3D display from one video data. According to this, an image can be displayed by a 3D display method using parallax based on the left-eye video signal and the right-eye video signal from the scaler substrate, and the projector device can display stereoscopic images not only by projection mapping but also by parallax.

  Next, the sub CPU 400 waits for a period of 2 msec, for example (S165). Thereafter, the sub CPU 400 proceeds to the process of S162.

[Screen character control processing]
FIG. 67 shows a screen accessory control process by the sub CPU 400 of the sub control board SS. As shown in the figure, the sub CPU 400 corresponds to the operation start step from the operation pattern of the screen mechanisms E1 and F1 constructed by the above-described screen accessory operation construction process, and the screen (projection target) changes. Is determined (S171). If the screen change occurs in the operation start step (S171: Yes), the sub CPU 400 proceeds to the next step S172. If it is not an operation start step or does not correspond to the occurrence of a screen change (S171: No), the sub CPU 400 proceeds to the process of S173.

  Next, the sub CPU 400 performs a focus change request process (S172). This process will be described later with reference to FIG.

  Next, the sub CPU 400 performs front screen control processing (S173). In this process, the sub CPU 400 controls the operation of the front screen drive mechanism E2 to move the front screen mechanism E1.

  Next, the sub CPU 400 performs a reel screen control process (S174). In this process, the sub CPU 400 controls the operation of the reel screen drive mechanism F2 in order to move the reel screen mechanism F1.

  Next, the sub CPU 400 determines whether or not the value of the focus standby counter is −1 (S175). The focus standby counter is a subtraction counter for generating a predetermined waiting time when the projector apparatus B2 changes the focus position. When the value of the focus standby counter is −1 (S175: Yes), the sub CPU 400 ends the screen accessory control process. When the value of the focus standby counter is not −1 (S175: No), the sub CPU 400 proceeds to the next process of S176.

  Next, the sub CPU 400 determines whether or not the value of the focus standby counter is 0 (S176). If the value of the focus standby counter is 0 (S176: Yes), the sub CPU 400 proceeds to the process of S178. When the value of the focus standby counter is not 0 (S176: No), the sub CPU 400 proceeds to the next process of S177.

  Next, the sub CPU 400 decrements the value of the focus standby counter by 1 (S177). Thereafter, the sub CPU 400 ends the screen accessory control process.

  In S178, the sub CPU 400 requests the projector device B2 to change the focus position after the change. In this processing, the sub CPU 400 stores focus position setting change request data in the sub device transmission storage area of the sub RAM board 41, and transmits this data to the projector apparatus B2. The focus position setting change request data includes the current focus position before the change and the focus position after the change. Thereby, for example, when the image projection target is switched from the front screen mechanism E1 to the reel screen mechanism F1 or vice versa, the projector device B2 changes the focus position setting. The focus mechanism 242 is controlled based on the request data, and the projection lens 210 can be focused at the focus position corresponding to each of the screen mechanisms E1 and F2.

  Next, the sub CPU 400 sets −1 in the focus standby counter (S179). Thereafter, the sub CPU 400 ends the screen accessory control process.

[Change focus request processing]
FIG. 68 shows focus change request processing by the sub CPU 400 of the sub control board SS. As shown in the figure, the sub CPU 400 obtains the current focus position (focus position A to E offset) from the current operation state of the screen mechanisms E1 and F1 (S181).

  Next, the sub CPU 400 acquires the changed focus position (focus position A to E offset) from the operation pattern of the screen mechanisms E1 and F1 constructed from the registered accessory data (S182).

  Next, the sub CPU 400 calculates the number of focus change pulses (S183). The focus change pulse number is the number of pulses of the motor drive signal supplied to the focus motor 242C when the focus position is changed, and is a required pulse number corresponding to the current focus position minus the changed focus position. Calculated as an absolute value.

  Next, the sub CPU 400 calculates a focus adjustment time (S184). The focus adjustment time is an actual working time of the focus mechanism 242 for changing the focus position. For example, when a motor drive signal for the focus motor 242C is a pulse square wave with a duty ratio of 0.5, a time (pulse) (Cycle) is multiplied by the number of focus change pulses obtained in S183.

  Next, the sub CPU 400 calculates a transmission time (setting change transmission time) for changing the focus position setting by communication with the projector control board B23 (S185). This setting change transmission time is the transmission time 1 of data exchanged between the sub control board SS and the scaler board SK and the transmission of data exchanged between the scaler board SK and the projector control board B23 in accordance with the setting change of the focus position. It is calculated as the combined time with time 2. Transmission time 1 is obtained by multiplying 1 / baud rate 1 by the number of transmission bits, which is the number of data × (data length + parity + start + stop). Similarly, the transmission time 2 is obtained by multiplying the number of transmission bits by 1 / baud rate 2. In this embodiment, the baud rate 1 is 38400 bps, the baud rate 2 is 19200 bps, the data length is 8 bits, there is no parity, the start and stop bits are 1 bit, and the transmission time 1 and the transmission time 2 obtained using these numerical values. Is calculated.

  Next, the sub CPU 400 calculates a focus change time (S186). The focus change time is calculated as the sum of the setting change transmission time obtained in S185 and the focus adjustment time obtained in S184.

  Next, the sub CPU 400 determines whether or not to change to the front screen mechanism E1 (S187). In the case of a change to the front screen mechanism E1 (S187: Yes), the sub CPU 400 proceeds to the next process of S188. If it is not a change to the front screen mechanism E1 (S187: No), the sub CPU 400 proceeds to the process of S189.

  Next, the sub CPU 400 calculates a moving time 1 for moving the front screen mechanism E1 to a predetermined position (S188). This moving time 1 is the actual working time of the front screen drive mechanism E2. For example, if the motor drive signal for the drive motor E25 of the front screen drive mechanism E2 is a pulse square wave with a duty ratio of 0.5, the pulse width is doubled. It is calculated by multiplying the required time by the required number of motor pulses. Thereafter, the sub CPU 400 proceeds to the process of S190.

  In S189, the sub CPU 400 calculates a moving time 2 when moving the reel screen mechanism F1 to a predetermined position. This movement time 2 is the actual working time of the reel screen drive mechanism F2. For example, if the motor drive signal for the drive motor F24 of the reel screen drive mechanism F2 is a pulse square wave with a duty ratio of 0.5, the pulse width is doubled. It is calculated by multiplying the required time by the required number of motor pulses.

  Next, the sub CPU 400 divides the difference between the movement times 1 and 2 obtained in S188 or S189 and the focus change time obtained in S186 by 2 corresponding to 2 msec of the processing cycle of the screen accessory control task, and calculates the result. A value corresponding to time is set in the focus standby counter (S190). As a result, for the operation of moving the screen mechanisms E1 and F1 to the predetermined position and the operation of changing the focus position, values that are just the difference between the required times are not set in the focus standby counter. The focus position can be changed to a predetermined position at the timing when the movement operation of F1 is completed. That is, it is possible to project an image with good image quality that is in focus (focus) by changing the focus position even on the screen mechanisms E1 and F1 immediately after the movement.

  Next, the sub CPU 400 determines whether or not there is focus interlock when displaying the video (for example, “1” when there is a focus interlock flag (not shown), “0” when there is no focus interlock) (S191). . The focus interlock means that the focus position is continuously changed in conjunction with the movement of the screen mechanisms E1 and F1. If there is no focus interlock (S191: No), the sub CPU 400 proceeds to the next step S192. If there is focus interlock (S191: Yes), the sub CPU 400 ends the focus change request process.

  Next, the sub CPU 400 sets 0 in the focus standby counter (S192). That is, when the focus interlock is not performed, the focus position is immediately changed at the beginning of the movement of the screen mechanisms E1 and F1, and when the focus interlock is performed, the focus position is at the timing when the movement of the screen mechanisms E1 and F1 is completed. The change of is finished. Thereafter, the sub CPU 400 ends the focus change request process.

[Main Task]

  Next, the sub CPU 400 acquires a reception command from the main control board MS from the communication message queue (S212).

  Next, the sub CPU 400 determines whether or not there is a reception command (S213). When there is a reception command (S213: Yes), the sub CPU 400 proceeds to the next process of S214. When there is no reception command (S213: No), the sub CPU 400 proceeds to the process of S218.

  Next, the sub CPU 400 checks the received command (S214).

  Next, the sub CPU 400 determines whether or not the received command is a valid command (S215). If the received command is a valid command (S215: Yes), the sub CPU 400 proceeds to the process of the next S216. When the received command is not a valid command (S215: No), the sub CPU 400 proceeds to the process of S218. Note that the received command is valid, for example, that the value of the command is in the range of 01H to 10H.

  Next, the sub CPU 400 creates game information from the received command, and stores the game information in a predetermined area (not shown) of the sub RAM board 41 (S216). This game information includes, for example, an internal winning combination, a gaming state, a set value, the number of bonus games, and the like.

[Subdevice reception interrupt processing]
FIG. 74 shows sub device reception interrupt processing by the sub CPU 400 of the sub control board SS. The sub-device reception interrupt process is a reception interrupt process for capturing the communication data transmitted by the scaler substrate SK in response to an external request from the sub-device (sub liquid crystal display device DD19, touch panel DD19T, projector device B2, etc.). As shown in the figure, the sub CPU 400 determines whether or not the received data from the sub device is 'STX' indicating the start of data (S251). When the received data is “STX (Start of TeXt: 02H)” (S251: Yes), the sub CPU 400 proceeds to the process of the next S252. When the received data is not “STX” (S251: No), the sub CPU 400 proceeds to the process of S253.

  Next, the sub CPU 400 sets the ETX reception flag and the reception completion flag in the flag storage area of the sub RAM board 41 to “OFF”, and clears the sub device reception storage area (S252). Thereafter, the sub CPU 400 ends the sub device reception interrupt process.

  In S253, the sub CPU 400 stores the received data in the sub device reception storage area of the sub RAM board 41.

  Next, the sub CPU 400 determines whether or not the received data from the sub device is “ETX” indicating the end of the data (S254). When the received data is “ETX (End of TeXt: 03H)” (S254: Yes), the sub CPU 400 proceeds to the process of the next S255. When the received data is not “ETX” (S254: No), the sub CPU 400 proceeds to the process of S256.

  Next, the sub CPU 400 sets the ETX reception flag in the flag storage area of the sub RAM board 41 to 'ON' (S255). Thereafter, the sub CPU 400 ends the sub device reception interrupt process.

  In S256, the sub CPU 400 determines whether or not the ETX reception flag in the flag storage area of the sub RAM board 41 is 'ON'. When the ETX reception flag is “ON” (S256: Yes), the sub CPU 400 proceeds to the next process of S257. When the ETX reception flag is not “ON” (S256: No), the sub CPU 400 ends the sub device reception interrupt process.

  Next, the sub CPU 400 performs a sub device received data sum check process (S257).

  Next, the sub CPU 400 determines whether or not the sum value obtained in S257 is normal (S258). When the sum value is normal (S258: Yes), the sub CPU 400 proceeds to the process of S260. When the sum value is not normal (S258: No), the sub CPU 400 proceeds to the next process of S259. Specifically, in this embodiment, when determining whether or not the sum value is normal, the received data up to “ETX”, excluding “STX” of the received data, is added and received after “ETX”. The consistency of the sum value is determined by collating with the received data. The method for calculating the sum value is not limited to the addition formula, and a subtraction formula or exclusive OR (also referred to as BCC) may be used.

  Next, the sub CPU 400 discards the data in the sub device reception storage area (clears the sub device reception storage area) (S259). Thereafter, the sub CPU 400 ends the sub device reception interrupt process.

[Subdevice initialization processing]
FIG. 75 shows sub-device initialization processing by the sub CPU 400 of the sub control board SS. As shown in the figure, the sub CPU 400 initializes a first serial line that is a communication line with the scaler substrate SK (S271).

  Next, the sub CPU 400 copies the value of the scaler setting value storage area of the SRAM 401 to the scaler setting value storage area of the sub RAM board 41 (S272). As shown in FIG. 62, the scaler setting values are the output screen division setting number, the input screen division setting number, the output screen 1 to 4 horizontal resolution, the output screen 1 to 4 vertical resolution, the input screen 1 and 2 horizontal resolution, and the input. This corresponds to a device profile indicating the control characteristics of the scaler substrate SK such as the screen 1 and the vertical resolution.

  Next, the sub CPU 400 performs a check process on the range of the scaler setting value stored in the scaler setting value storage area (S273).

  Next, the sub CPU 400 determines whether or not all the scaler setting values in the scaler setting value storage area are values within the valid range (S274). As shown in FIG. 54, the effective range of the scaler set value is defined in advance as a transmission command from the sub control board SS. If all the scaler set values are within the valid range (S274: Yes), the sub CPU 400 proceeds to the process of S276. When at least one scaler setting value is not within the valid range (S274: No), the sub CPU 400 proceeds to the next process of S275.

  Next, the sub CPU 400 initializes the scaler setting value storage area of the SRAM 401 and the scaler setting value storage area of the sub RAM board 41 as initial values (S275). As shown in FIG. 62, the initial value of the scaler setting value is written in advance in the scaler initial value area of the sub-ROM substrate 42.

  Next, the sub CPU 400 copies the value of the sub liquid crystal setting value storage area of the SRAM 401 to the sub liquid crystal setting value storage area of the sub RAM board 41 (S276). As shown in FIG. 62, the sub liquid crystal setting value corresponds to a device profile indicating display characteristics of the sub liquid crystal display device DD19 such as sub liquid crystal horizontal resolution, sub liquid crystal vertical resolution, and sub liquid crystal luminance.

  Next, the sub CPU 400 performs a check process on the range of the sub liquid crystal setting values stored in the sub liquid crystal setting value storage area (S277).

  Next, the sub CPU 400 determines whether or not all the sub liquid crystal setting values in the sub liquid crystal setting value storage area are values within the effective range (S278). When all the sub liquid crystal setting values are values within the effective range (S278: Yes), the sub CPU 400 proceeds to the process of S280. If at least one sub liquid crystal set value is not within the valid range (S278: No), the sub CPU 400 proceeds to the next step S279.

  Next, the sub CPU 400 initializes the sub liquid crystal setting value storage area of the SRAM 401 and the sub liquid crystal setting value storage area of the sub RAM substrate 41 as initial values (S279). The initial value of the sub liquid crystal setting value is written in advance in the sub liquid crystal initial value area of the sub ROM substrate 42 as shown in FIG.

  Next, the sub CPU 400 copies the value of the projector setting value storage area of the SRAM 401 to the projector setting value storage area of the sub RAM board 41 (S280). As shown in FIG. 62, the projector set values are the horizontal position A to E adjustment value, the horizontal position A to E offset, the vertical position A to E adjustment value, the vertical position A to E offset, and the focus position offset. This corresponds to a device profile indicating the display characteristics of the projector apparatus B2, such as A to E, LED luminance setting, trapezoidal distortion correction value, white color temperature setting, brightness setting, contrast setting, gamma setting, and focus drift correction value A to E.

  Next, the sub CPU 400 performs a check process on the range of the projector setting value stored in the projector setting value storage area (S281).

  Next, the sub CPU 400 determines whether or not all projector setting values in the projector setting value storage area are values within the valid range (S282). When all the projector setting values are values within the valid range (S282: Yes), the sub CPU 400 proceeds to the process of S284. If at least one projector setting value is not within the valid range (S282: No), the sub CPU 400 proceeds to the next process of S283.

  Next, the sub CPU 400 initializes the projector setting value storage area of the SRAM 401 and the projector setting value storage area of the sub RAM board 41 as initial values (S283). The initial value of the projector setting value is written in advance in the projector initial value area of the sub-ROM board 42 as shown in FIG.

  Next, the sub CPU 400 sets the scaler setting completion flag, the sub liquid crystal setting completion flag, and the projector setting completion flag in the flag storage area of the sub RAM board 41 to 'OFF' (S284). Thereafter, the sub CPU 400 ends the sub device initialization process.

[Scaler control processing]
FIG. 76 shows a scaler control process by the sub CPU 400 of the sub control board SS. As shown in the figure, the sub CPU 400 determines whether or not the transmission source ID of the reception data temporarily stored in the sub device reception storage area of the sub RAM board 41 indicates “scaler (ID: 02H shown in FIG. 53)”. Is determined (S291). When the transmission source ID indicates “scaler” (S291: Yes), the sub CPU 400 proceeds to the next process of S292. When the transmission source ID does not indicate “scaler” (S291: No), the sub CPU 400 ends the scaler control process.

  Next, the sub CPU 400 performs a received data consistency check process for controlling the scaler board SK (S292). In this process, the sub CPU 400 checks whether or not the value of the command ID included in the received data matches the value of “01H” to “05H” indicating the transmission command from the scaler board SK shown in FIG. The check result is returned as a return value.

  Next, the sub CPU 400 determines from the return value of the check result whether there is an abnormality in the consistency of the received data (S293). If there is an abnormality in the consistency of the received data (S293: Yes), the sub CPU 400 proceeds to the process of the next S294. When there is no abnormality in the consistency of received data (S293: No), the sub CPU 400 proceeds to the process of S295.

  Next, the sub CPU 400 discards (clears) the data in the sub device reception storage area because the consistency of the reception data is abnormal (invalid reception data) (S294). Thereafter, the sub CPU 400 ends the scaler control process.

  In S295, the sub CPU 400 performs processing at the time of receiving the scaler control. This process will be described later with reference to FIG. Thereafter, the sub CPU 400 ends the scaler control process.

[Processing when receiving scaler control]
FIG. 77 shows processing at the time of receiving scaler control by the sub CPU 400 of the sub control board SS. As shown in the figure, the sub CPU 400 copies received data from the sub device reception storage area of the sub RAM board 41 to the scaler control reception storage area (S301).

  Next, the sub CPU 400 determines whether or not the command (reception command) acquired from the received data is an “activation parameter request” (S302). When the received command is “startup parameter request (see CMD: 01H shown in the left column of FIG. 54)” (S302: Yes), the sub CPU 400 proceeds to the next process of S303. When the received command is not “activation parameter request” (S302: No), the sub CPU 400 proceeds to the process of S304.

  Next, the sub CPU 400 performs processing for receiving a scaler activation parameter request (S303). This process will be described later with reference to FIG. Thereafter, the sub CPU 400 ends the scaler control reception process.

  In S304, the sub CPU 400 determines whether or not the command (reception command) acquired from the received data is “parameter request (see CMD: 02H shown in the left column of FIG. 54)”. If the received command is a “parameter request” (S304: Yes), the sub CPU 400 proceeds to the next process of S305. If the received command is not a “parameter request” (S304: No), the sub CPU 400 proceeds to the process of S311.

  Next, the sub CPU 400 issues a scaler set value change request (see CMD: 02H, D1: 01H shown in the left column of FIG. 54) based on the parameter value (see FIG. 54) included in the parameter request reception command. It is determined whether or not there is (S305). When there is a request to change the scaler setting value (S305: Yes), the sub CPU 400 proceeds to the next process of S306. When there is no request for changing the scaler setting value (S305: No), the sub CPU 400 proceeds to the process of S309.

  Next, the sub CPU 400 sets the scaler setting changing flag in the flag storage area of the sub RAM board 41 to ‘ON’ (S306).

  Next, the sub CPU 400 acquires the setting change content (scaler setting value to be changed) from the scaler setting value storage area (see FIG. 62) (S307).

  Next, the sub CPU 400 uses the acquired setting change content as an argument (a general name of the parameter on the software indicating that the caller delivers the parameter to the subroutine function (process) of the callee), and the scaler setting change process (S308). This process will be described later with reference to FIG. Thereafter, the sub CPU 400 ends the scaler control reception process.

  In S309, the sub CPU 400 receives a status request (see CMD: 02H and D1: 02H shown in the left column of FIG. 54) from the scaler board SK based on the parameter value (see FIG. 54) included in the parameter request reception command. It is determined whether or not there is. When there is a status request (S309: Yes), the sub CPU 400 proceeds to the next process of S310. When there is no status request (S309: No), the sub CPU 400 ends the process at the time of receiving the scaler control.

  Next, the sub CPU 400 performs a status request command transmission process (S310). In this process, the sub CPU 400 transmits a status request command to the scaler substrate SK. Thereafter, the sub CPU 400 ends the scaler control reception process.

  In S311, the sub CPU 400 determines whether or not the command (reception command) acquired from the reception data is “status” (see CMD: 03H shown in the left column of FIG. 54). When the received command is 'status' (S311: Yes), the sub CPU 400 proceeds to the next process of S312. If the received command is not 'status' (S311: No), the sub CPU 400 proceeds to the process of S313.

  Next, the sub CPU 400 performs processing at the time of receiving the scaler status command (S312). This process will be described later with reference to FIG. Thereafter, the sub CPU 400 ends the scaler control reception process.

  In S313, the sub CPU 400 determines whether or not the command (reception command) acquired from the received data is “reception confirmation (see CMD: 04H shown in the left column of FIG. 54)”. If the reception command is “reception confirmation” (S313: Yes), the sub CPU 400 proceeds to the next processing of S314. When the reception command is not “reception confirmation” (S313: No), the sub CPU 400 proceeds to the process of S315.

  Next, the sub CPU 400 performs a scaler reception confirmation reception process (S314). This process will be described later with reference to FIG.

  In S315, the sub CPU 400 determines whether or not the command (reception command) acquired from the reception data is “error notification (see CMD: 05H shown in the left column of FIG. 54)”. If the received command is “error notification” (S315: Yes), the sub CPU 400 proceeds to the next process of S316.

  Next, the MCU 700 waits for the watchdog timer (WDT) to be reset (S572). The watchdog timer reset wait is a process of performing an infinite loop process without clearing (or setting to a predetermined value) the watchdog timer and waiting for the watchdog timer to output a reset signal to the MCU 700. When the timer outputs a reset signal to the MCU 700, the MCU 700 is reset, and the process is restarted from the first step (S561) in the scaler board main process (also referred to as “reboot”). The same applies to S700 of the projector control main process described later and S871 of the sub liquid crystal control main process.

  In S573, the MCU 700 clears the value of the watchdog timer (WDT).

  Next, the MCU 700 waits for a period of 2 msec, for example (S574). Thereafter, the MCU 700 proceeds to the process of S562.

[First serial line reception interrupt processing]
FIG. 99 shows the first serial line reception interrupt processing by the MCU 700 of the scaler board SK. The first serial line reception interrupt process is a communication interrupt process for capturing received data in response to an external request from the sub-control board BB via the first serial line during execution of the scaler board main process. The MCU 700 is configured to execute a second serial line reception interrupt process and a third serial line reception interrupt process as well as the first serial line reception interrupt process. The second serial line reception interrupt process is a communication interrupt process that captures received data in response to an external request from the projector control board B23 that passes through the second serial line. This is a communication interrupt process for capturing received data in response to an external request from the sub liquid crystal I / F board SL via the three serial lines. The second and third serial line reception interrupt processes are substantially the same as the first serial line reception interrupt process except that the lines are different.

  As shown in FIG. 99, the MCU 700 determines whether or not the received data from the first serial line (sub control board SS) is “STX (02H)” indicating the start of data (S581). If the received data is 'STX' (S581: Yes), the MCU 700 proceeds to the next process of S582. If the received data is not 'STX' (S581: No), the MCU 700 proceeds to the process of S583.

  Next, the MCU 700 sets the first ETX reception flag and the first reception completion flag in the SDRAM 712 flag and other storage areas to “OFF”, and clears the first reception storage area (S582). Thereafter, the MCU 700 ends the first serial line reception interrupt process.

  In S583, the MCU 700 saves the reception data from the first serial line (sub control board SS) in the first reception storage area of the SDRAM 712.

  Next, the MCU 700 determines whether or not the received data is “ETX (03H)” indicating the end of the data (S584). If the received data is “ETX” (S584: Yes), the MCU 700 proceeds to the process of the next S585. When the received data is not “ETX” (S584: No), the MCU 700 proceeds to the process of S586.

  Next, the MCU 700 sets the flag of the SDRAM 712 and the first ETX reception flag in the other storage area to “ON” (S585). Thereafter, the MCU 700 ends the first serial line reception interrupt process.

  In S586, the MCU 700 determines whether the first ETX reception flag in the flag 712 other storage area of the SDRAM 712 is “ON” or not. When the first ETX reception flag is 'ON' (S586: Yes), the MCU 700 proceeds to the next process of S587. If the first ETX reception flag is not “ON” (S586: No), the MCU 700 ends the first serial line reception interrupt process.

  Next, the MCU 700 performs a received data sum check process (S587).

  Next, the MCU 700 determines whether or not the sum value obtained in S587 is normal (S588). When the sum value is normal (S588: Yes), the MCU 700 proceeds to the process of S590. When the sum value is not normal (S588: No), the MCU 700 proceeds to the process of the next S589. The sum value calculation method is the same as that described in the sub-device reception interrupt process (S258 in FIG. 74).

  Next, the MCU 700 discards the data in the first serial line reception storage area (S589). Thereafter, the MCU 700 ends the first serial line reception interrupt process.

  In S590, the MCU 700 sets the flag of the SDRAM 712 and the first reception completion flag in the storage area to “ON”. Thereafter, the MCU 700 ends the first serial line reception interrupt process.

  Next, the MCU 700 initializes the first to third serial lines (S602).

  Next, the MCU 700 acquires various initial setting values related to input / output of the multi-output scaler LSI 710 from the ROM (S603).

  Next, the MCU 700 performs initial settings related to input / output of the multi-output scaler LSI 710 (S604). In this processing, the MCU 700 performs initial settings for the DSF (α) 821 and DSF (β) 822 and select areas A to D801 to 804 of the multi-output scaler LSI 710 based on the initial setting values acquired from the ROM.

  Next, the MCU 700 sets the flag of the SDRAM 712 and the scaler LSI setting flag and the reset request flag in the storage area to “OFF” (S605). Thereafter, the MCU 700 ends the scaler initialization process.

[Sub-device bypass transmission processing]
FIG. 101 shows sub-device bypass transmission processing by the MCU 700 of the scaler substrate SK. As shown in the figure, the MCU 700 determines whether or not the destination ID of the received data indicates “projector (30H)” (S611). When the transmission destination ID indicates “projector” (S611: Yes), the MCU 700 proceeds to the process of the next S612. When the transmission destination ID does not indicate “projector” (S611: No), the MCU 700 proceeds to the process of S614.

  Next, the MCU 700 copies the data once taken into the first reception storage area of the SDRAM 712 to the second transmission storage area (S612).

  Next, the MCU 700 performs a second serial line transmission process (S613). In this processing, the MCU 700 outputs the data transmitted from the sub control board SS to the projector control board B23 to the second serial line. Thereafter, the MCU 700 ends the sub device bypass transmission process.

  In S614, the MCU 700 determines whether or not the transmission destination ID of the received data indicates “sub liquid crystal (ID: 40H shown in FIG. 53)”. When the transmission destination ID indicates “sub liquid crystal” (S614: Yes), the MCU 700 proceeds to the next process of S615. When the transmission destination ID does not indicate “sub liquid crystal” (S614: No), the MCU 700 ends the sub device bypass transmission process.

  Next, the MCU 700 copies the data once taken into the first reception storage area of the SDRAM 712 to the third transmission storage area (S615).

  Next, the MCU 700 performs third serial line transmission processing (S616). In this process, the MCU 700 outputs the data transmitted from the sub control board SS to the sub liquid crystal I / F board SL to the third serial line. Thereafter, the MCU 700 ends the sub device bypass transmission process.

[Processing during reception between sub-control and scaler]
FIG. 102 shows the sub control-scaler reception process by the MCU 700 of the scaler substrate SK. As shown in the figure, the MCU 700 receives a command (CMD) of received data (hereinafter referred to as “acquired received data” in this process) acquired from the first reception storage area of the SDRAM 712 by the sub control board SS through S563. It is determined whether or not it is a status request (see CMD: 03H shown in the right column of FIG. 54) (S621). When the acquired command of received data is “status request” (S621: Yes), the MCU 700 proceeds to the processing of the next S622. When the acquired received data command is not “status request” (S621: No), the MCU 700 proceeds to the process of S624.

  Next, the MCU 700 registers a command transmission request indicating a “status” corresponding to the output setting (D1: 01H) and the input setting (D1: 02H) of the “status request” to the sub control board SS (S622). ).

  Next, the MCU 700 stores various parameter values (D1) included in the acquired received data in the status storage area of the SDRAM 712 (S623). Thereafter, the MCU 700 ends the sub-control-scaler reception process.

  In S624, the MCU 700 determines whether or not the command of the acquired reception data is “setting complete (see CMD: 02H shown in the right column of FIG. 54)”. If the acquired received data command is “setting complete” (S624: Yes), the MCU 700 proceeds to the next processing of S625. If the acquired received data command is not 'setting complete' (S624: No), the MCU 700 proceeds to the process of S626.

  Next, the MCU 700 changes the setting of the multi-output scaler LSI 710 with the setting value in the scaler LSI setting storage area of the SDRAM 712 (S625). Thereafter, the MCU 700 proceeds to the process of S636.

  In S626, the MCU 700 determines whether or not the command of the acquired reception data is “activation parameter request confirmation (see CMD: 01H shown in the right column of FIG. 54)”. If the acquired command of received data is “startup parameter request confirmation” (S626: Yes), the MCU 700 proceeds to the next processing of S627. When the acquired command of the received data is not “activation parameter request confirmation” (S626: No), the MCU 700 proceeds to the process of S628.

  Next, the MCU 700 sets the flag scaler LSI setting flag in the other storage area of the SDRAM 712 to “ON” (S627). Thereafter, the MCU 700 proceeds to the process of S636.

  In S628, the MCU 700 determines whether or not the command of the acquired reception data is “output screen division setting number (see CMD: 05H shown in the right column of FIG. 54)”. If the acquired received data command is “output screen division setting number” (S628: Yes), the MCU 700 proceeds to the process of the next S629. When the acquired received data command is not the “output screen division setting number” (S628: No), the MCU 700 proceeds to the process of S630.

  Next, the MCU 700 saves the output screen division setting number included in the acquired received data in the scaler LSI setting storage area of the SDRAM 712 (S629). Thereafter, the MCU 700 proceeds to the process of S636.

  In S630, the MCU 700 determines whether or not the command of the acquired reception data is “output screen resolution setting (see CMD: 06H shown in the right column of FIG. 54)”. If the acquired received data command is “output screen resolution setting” (S630: Yes), the MCU 700 proceeds to the next processing of S631. If the acquired received data command is not “output screen resolution setting” (S630: No), the MCU 700 proceeds to the process of S632.

  Next, the MCU 700 stores the output screen resolution included in the acquired received data in the scaler LSI setting storage area of the SDRAM 712 (S631). Thereafter, the MCU 700 proceeds to the process of S636.

If the acquired received data command is not the “input screen division setting number” (S632: No), the MCU 700 proceeds to the process of S634.

  Next, the MCU 700 stores the input screen division setting number included in the acquired received data in the scaler LSI setting storage area of the SDRAM 712 (S633). Thereafter, the MCU 700 proceeds to the process of S636.

  In step S634, the MCU 700 determines whether or not the command of the acquired reception data is “input screen resolution setting (see CMD: 08H shown in the right column of FIG. 54)”. If the acquired received data command is “input screen resolution setting” (S634: Yes), the MCU 700 proceeds to the process of the next S635. When the acquired received data command is not “input screen resolution setting” (S634: No), the MCU 700 indicates that the acquired received data command is “status request complete (see CMD: 04H shown in the right column of FIG. 54)”. Therefore, the process proceeds to S636.

  Next, the MCU 700 saves the input screen resolution included in the acquired received data in the scaler LSI setting storage area of the SDRAM 712 (S635).

  Next, the MCU 700 registers a transmission request for a command indicating “reception confirmation (see CMD: 04H shown in the left column of FIG. 54)” with respect to the sub control board SS (S636). Thereafter, the MCU 700 ends the sub-control-scaler reception process.

[Scalar self-diagnosis processing]
FIG. 103 shows a scaler self-diagnosis process performed by the MCU 700 of the scaler substrate SK. As shown in the figure, the MCU 700 writes, for example, “55AAH” as the diagnostic value read from the ROM in the self-diagnosis storage area of the SDRAM 712 by the verify check (S641).

  Next, the MCU 700 determines whether or not the value (load value) read from the self-diagnosis storage area correctly matches the diagnosis value (S642). When the load value matches the diagnosis value (S642: Yes), the MCU 700 proceeds to the process of S644. If the load value does not match the diagnostic value (S642: No), the MCU 700 proceeds to the next process of S643.

  Next, the MCU 700 sets “self-diagnostic abnormality” as error data in the error management area of the SDRAM 712 (S643).

  Next, the MCU 700 reads the status of the multi-output scaler LSI 710 (S644).

  Next, the MCU 700 determines whether or not the status of the multi-output scaler LSI 710 is normal (S645). When the status of the multi-output scaler LSI 710 is normal (S645: Yes), the MCU 700 proceeds to the process of S647. When the status of the multi-output scaler LSI 710 is not normal (S645: No), the MCU 700 proceeds to the next process of S646.

  Next, the MCU 700 sets “WDT (watchdog timer) -scaler abnormality” as error data in the error management area of the SDRAM 712 (S646).

  Next, the MCU 700 reads the output setting of the multi-output scaler LSI 710 (S647).

  Next, the MCU 700 determines whether or not the data related to the output setting stored in the scaler LSI setting storage area of the SDRAM 712 and the output setting of the implementation of the multi-output scaler LSI 710 are the same set value (S648). When the output setting data of the SDRAM 712 and the actual output setting are the same setting value (S648: Yes), the MCU 700 proceeds to the process of S650. When the output setting data of the SDRAM 712 is different from the actual output setting (S648: No), the MCU 700 proceeds to the next process of S649.

  Next, the MCU 700 sets “scaler output setting abnormality” as error data in the error management area of the SDRAM 712 (S649).

  Next, the MCU 700 reads the input settings of the multi-output scaler LSI 710 (S650).

  Next, the MCU 700 determines whether or not the data related to the input settings stored in the scaler LSI setting storage area of the SDRAM 712 and the input settings of the multi-output scaler LSI 710 are the same set values (S651). When the input setting data of the SDRAM 712 and the actual input setting are the same setting value (S651: Yes), the MCU 700 ends the scaler self-diagnosis process. If the input setting data of the SDRAM 712 is different from the actual input setting (S651: No), the MCU 700 proceeds to the next processing of S652.

  Next, the MCU 700 sets “scaler input setting abnormality” as error data in the error management area of the SDRAM 712 (S652). Thereafter, the MCU 700 ends the scaler self-diagnosis process.

[Transmission between sub-control and scaler]
FIG. 104 shows processing during transmission between the sub control and the scaler by the MCU 700 of the scaler substrate SK. As shown in the figure, the MCU 700 adds 1 to the transmission cycle counter (S661). This transmission cycle counter is an addition counter for measuring the cycle of transmitting a command from the scaler board SK.

  Next, the MCU 700 determines whether or not the value of the transmission cycle counter is, for example, 100 or more as a predetermined value (S662). When the value of the transmission cycle counter is equal to or larger than the predetermined value (S662: Yes), the MCU 700 proceeds to the process of the next S663. If the value of the transmission cycle counter is less than the predetermined value (S662: No), the MCU 700 ends the sub-control-scaler transmission process. In the present embodiment, since the processing is performed at a cycle of 2 msec in the scaler substrate main processing described above, the value of the transmission cycle counter being 100 or more is 2 msec × 100 = 200 msec or more. As a result, data is transmitted to the sub-control board SS approximately at a cycle of 200 msec. However, the present invention is not limited to this, and the predetermined value of the transmission cycle counter is an arbitrary value (for example, transmission cycle counter: 50 × 2 msec). = 100 msec cycle).

  Next, the MCU 700 clears the value of the transmission cycle counter (S663).

  Next, the MCU 700 determines whether the flag of the SDRAM 712 and the scaler LSI setting flag in the storage area are 'OFF' (S664). When the scaler LSI setting flag is “OFF” (S664: Yes), the MCU 700 proceeds to the process of the next S665. When the scaler LSI setting flag is not “OFF” (S664: No), the MCU 700 proceeds to the process of S666.

  Next, the MCU 700 creates, as transmission data, a command indicating “activation parameter request (see CMD: 01H shown in the left column of FIG. 54)” for the sub-control board SS (S665). This transmission data is stored in the first transmission storage area of the SDRAM 712, and is transmitted as a transmission command to the sub control board SS by a first serial line transmission process of S676 described later. After the process of S665, the MCU 700 proceeds to the process of S676.

  In S <b> 666, the MCU 700 determines whether error data exists in the error management area of the SDRAM 712.

  In S669, the MCU 700 determines whether or not there is a command transmission request indicating “reception confirmation (see CMD: 04H shown in the left column of FIG. 54)” with respect to the sub control board SS. When there is a transmission request for a command indicating 'reception confirmation' (S669: Yes), the MCU 700 proceeds to the next processing of S670. If there is no transmission request for a command indicating 'reception confirmation' (S669: No), the MCU 700 proceeds to the process of S671.

  Next, the MCU 700 creates a command indicating “reception confirmation” as transmission data for the sub control board SS (S670). This transmission data is stored in the first transmission storage area of the SDRAM 712, and is transmitted as a transmission command to the sub control board SS by a first serial line transmission process of S676 described later. After the process of S670, the MCU 700 proceeds to the process of S676.

  In S671, the MCU 700 determines whether or not there is a command transmission request indicating “status (see CMD: 03H shown in the left column of FIG. 54)” with respect to the sub control board SS. If there is a transmission request for a command indicating 'status' (S671: Yes), the MCU 700 proceeds to the next processing of S672. If there is no transmission request for a command indicating 'status' (S671: No), the MCU 700 proceeds to the process of S675.

  Next, the MCU 700 determines whether or not the data in the status storage area of the SDRAM 712 is data relating to output settings (S672). When the data in the status storage area is data related to the output setting (D1: 01H) (S672: Yes), the MCU 700 proceeds to the process of the next S673. When the data in the status storage area is not data relating to output setting, that is, data relating to input setting (D1: 02H) (S672: No), the MCU 700 proceeds to the process of S674.

  Next, the MCU 700 creates, as transmission data, a command indicating “status” related to output setting for the sub-control board SS (S673). This transmission data is stored in the first transmission storage area of the SDRAM 712, and is transmitted as a transmission command to the sub control board SS by a first serial line transmission process of S676 described later. After the process of S673, the MCU 700 proceeds to the process of S676.

  In step S674, the MCU 700 creates a command indicating “status” related to the input setting for the sub control board SS as transmission data. This transmission data is stored in the first transmission storage area of the SDRAM 712, and is transmitted as a transmission command to the sub control board SS by a first serial line transmission process of S676 described later. After the process of S674, the MCU 700 proceeds to the process of S676.

  In S675, the MCU 700 creates a command indicating “parameter request” for the sub control board SS as transmission data. This transmission data is stored in the first transmission storage area of the SDRAM 712, and is transmitted as a transmission command to the sub control board SS by the first serial line transmission processing of the next S676.

  Next, the MCU 700 performs a first serial line transmission process (S676). By this transmission processing, various commands are transmitted from the scaler substrate SK to the sub control substrate SS. Thereafter, the MCU 700 ends the sub-control-scaler transmission process.

[Sub control bypass transmission processing]
FIG. 105 shows sub control bypass transmission processing by the MCU 700 of the scaler substrate SK. As shown in the figure, the MCU 700 determines whether or not the second reception completion flag in the flag and other storage areas of the SDRAM 712 is 'ON' (S681). When the second reception completion flag is “ON” (S681: Yes), the MCU 700 proceeds to the next process of S682. When the second reception completion flag is not “ON” (S681: No), the MCU 700 proceeds to the process of S684.

  Next, the MCU 700 determines whether or not the transmission destination ID of the data stored in the second reception storage area of the SDRAM 712 indicates “sub control” (S682). When the transmission destination ID indicates “sub control” (S682: Yes), the MCU 700 proceeds to the processing of the next S683. When the transmission destination ID does not indicate “sub control” (S682: No), the MCU 700 proceeds to the process of S684.

  Next, the control LSI 230 determines whether or not the reception completion flag in the various flags & work area of the DRAM is “ON” (S692). When the reception completion flag is “ON” (S692: Yes), the control LSI 230 proceeds to the next process of S693. When the reception completion flag is not “ON” (S692: No), the control LSI 230 shifts to the process of S697.

  Next, the MCU 900 sends an “error notification (see CMD: 45H shown in the left column of FIG. 55)” command to the sub control board SS in an error management area (CMD: 45H, D1: error information shown in the left column of FIG. 55). The transmission data is created (S945). This transmission data is stored in the transmission storage area of the DRAM, and is transmitted as a transmission command to the sub control board SS by a third serial line transmission process in S956 described later.

  Next, the MCU 900 sets a reset request flag in various storage areas of the DRAM to ‘ON’ (S946). Thereafter, the MCU 900 proceeds to the process of S956.

  In step S947, the MCU 900 determines whether or not the sub liquid crystal setting flag in the flag area of the DRAM is “OFF”. When the sub liquid crystal setting flag is “OFF” (S947: Yes), the MCU 900 proceeds to the next process of S948. If the sub liquid crystal setting flag is not “OFF” (S947: No), the MCU 900 proceeds to the process of S949.

  Next, the MCU 900 creates transmission data of a “startup parameter request (see CMD: 41H shown in the left column of FIG. 55)” command for the sub control board SS (S948). This transmission data is stored in the transmission storage area of the DRAM, and is transmitted as a transmission command to the sub control board SS by a third serial line transmission process in S956 described later. After the process of S948, the MCU 900 proceeds to the process of S956.

  In S949, the MCU 900 determines whether or not there is a transmission request for the “reception confirmation” command to the sub control board SS. If there is a transmission request for the 'reception confirmation' command (S949: Yes), the MCU 900 proceeds to the next processing of S950. When there is no transmission request for the “reception confirmation” command (S949: No), the MCU 900 proceeds to the process of S951.

  Next, the MCU 900 creates transmission data of the “reception confirmation (see CMD: 44H shown in the left column of FIG. 55)” command with respect to the sub-control board SS (S950). This transmission data is stored in the transmission storage area of the DRAM, and is transmitted as a transmission command to the sub control board SS by a third serial line transmission process in S956 described later. After the process of S950, the MCU 900 proceeds to the process of S956.

  In step S951, the MCU 900 determines whether there is a transmission request for the “status” command to the sub control board SS. If there is a transmission request for the 'status' command (S951: Yes), the MCU 900 proceeds to the next process of S952. If there is no transmission request for the 'status' command (S951: No), the MCU 900 proceeds to the process of S955.

  Next, the MCU 900 determines whether or not the data type in the status storage area of the DRAM relates to touch input (S952). If the data type of the status storage area is related to touch input (S952: Yes), the MCU 900 proceeds to the next process of S953. When the data type of the status storage area is not related to touch input, that is, related to liquid crystal setting (S952: No), the MCU 900 proceeds to the process of S954.

  Next, the MCU 900 creates the transmission data by adding the touch panel input area data to the 'status (see CMD: 43H shown in the left column of FIG. 55)' command related to the touch input to the sub control board SS (S953). ). This transmission data is stored in the transmission storage area of the DRAM, and is transmitted as a transmission command to the sub control board SS by a third serial line transmission process in S956 described later. After the process of S953, the MCU 900 proceeds to the process of S956.

  In S954, the MCU 900 creates transmission data of a command indicating “status (refer to CMD: 43H shown in the left column of FIG. 55)” related to the liquid crystal setting for the sub control board SS. This transmission data is stored in the third transmission storage area of the DRAM, and is transmitted as a transmission command to the sub control board SS by a third serial line transmission process in S956 described later. After the process of S954, the MCU 900 proceeds to the process of S956.

  In step S955, the MCU 900 creates transmission data of a command indicating “parameter request (see CMD: 42H shown in the left column of FIG. 55)” for the sub control board SS. This transmission data is stored in the third transmission storage area of the DRAM, and is transmitted as a transmission command to the sub-control board SS by the third serial line transmission processing of the next S956.

  Next, the MCU 900 performs a third serial line transmission process (S956). By this transmission processing, various commands are transmitted from the sub liquid crystal I / F substrate SL to the sub control substrate SS via the scaler substrate SK. Thereafter, the MCU 900 ends the sub-control-sub liquid crystal transmission process.

(Optical adjustment of projector device B2)
FIG. 123 is a diagram showing a test pattern projected during optical adjustment of projector device B2. A factory inspection person (also called a quality assurance person) activates application software for optical adjustment on the adjustment PC 1000 and performs a predetermined operation according to the menu of the software, whereby the fixed screen mechanism D and the front screen mechanism E1. Alternatively, the reel screen mechanism F1 can be operated to display a test pattern TP as shown in FIG. 123 on each projection plane. FIG. 123 shows a state where the test pattern TP is displayed on the reflection portion D1 of the fixed screen mechanism D as an example. The factory inspection worker can observe the display mode of the test pattern TP from the upper display window UD1 of the gaming machine 1.

  The test pattern TP is, for example, a pattern in which a SMPTE (Society of Motion Picture and Television Engineers) color bar is sprite-shaped in a circle and small circular patterns arranged in four corners on a background cross-hatch pattern It is.

  Specifically, the factory inspector operates the fixed screen mechanism D, the front screen mechanism E1, and the reel screen mechanism F1 so that they are projection targets. While observing the display mode of the test pattern TP, the projector apparatus B2 can be adjusted so that the display mode is appropriate. Thereby, for the projector device B2, the horizontal position adjustment value, the vertical position adjustment value, the focus position adjustment value, the LED brightness setting, the keystone distortion correction value, the white color temperature setting, the brightness setting, the contrast setting, the gamma setting, and the test. Optical adjustment can be performed for each item such as a pattern, a horizontal position offset, a vertical position offset, and a focus position offset.

  In this embodiment, at the time of adjustment work such as before assembly of the gaming machine, identification symbols 'A' to 'C' are assigned to the fixed screen mechanism D, the front screen mechanism E1, and the reel screen mechanism F1, for example. Using these identification symbols, different horizontal position A to C adjustment values, vertical position A to C adjustment values, and focus position A to C adjustment values for each projection target are set in the EEPROM 231 of the projector control board B23. Other adjustment items (LED brightness setting, keystone distortion correction value, white color temperature setting, brightness setting, contrast setting, gamma setting, test pattern, horizontal position offset, vertical position offset, focus position offset) After being assembled, it is set in the SRAM 401 of the sub control board SS. Note that the horizontal position offset, the vertical position offset, and the focus position offset can be adjusted by offset adjustment by a maintenance worker at a site such as a game arcade at the factory.

  On the other hand, FIG. 124 is a diagram showing a test pattern TP ′ and the like displayed on the screen (touch panel DD19T) of the sub liquid crystal display device DD19 at the time of optical adjustment of the projector device B2 in the field such as a game hall. After the gaming machine 1 is installed in a game arcade or the like, the test pattern TP ′ or the like can be displayed on the touch panel DD19T serving as the screen of the sub liquid crystal display device DD19 by performing a predetermined operation by the maintenance worker. . The maintenance worker can appropriately perform optical adjustment of the projector apparatus B2 individually using such a test pattern TP '.

  Unlike the test pattern TP displayed directly on the projection target, the test pattern TP ′ displayed on the touch panel DD19T is displayed as an operation target that can be intuitively deformed as a virtual image by simulation. In addition, the touch panel DD19T displays buttons T1 and T2 for changing the setting of horizontal position offset, vertical position offset, focus position offset, and focus drift correction for each projection target, as well as trapezoidal distortion correction and LED brightness. A button T3 and an indicator T4 for changing the setting of white color temperature, brightness, contrast, and gamma value are displayed, and a numeric keypad T5 for inputting various numerical values is also displayed.

  Specifically, the maintenance worker displays a test pattern TP ′ or the like on the touch panel DD19T by performing a predetermined operation, and any one of the fixed screen mechanism D, the front screen mechanism E1, and the reel screen mechanism F1 is projected. Operate to be the target. Thereafter, the maintenance operator operates the buttons T1 and T2 to select any one of the horizontal position offset, the vertical position offset, the focus position offset, and the focus drift correction, and the test pattern TP ′ is directly selected by operating the touch panel. Adjustment can be performed so that the display mode becomes appropriate while changing. In other words, the display position of the test pattern TP ′ changes vertically and horizontally and the image quality changes according to the operation of the maintenance worker. Thereby, about projector apparatus B2, a setting change can be performed for every different projection object about horizontal position offset, vertical position offset, focus position offset, and focus drift correction. At this time, the maintenance operator can also observe the actual test pattern TP because the test pattern TP is projected from the projector device B2 onto the national screen mechanism D at the same time. The horizontal position offset, vertical position offset, focus position offset, and focus drift correction are set in the projector setting value storage area of the SRAM 401 and the projector setting value storage area of the sub RAM board 41 of the sub control board SS.

  In addition, the maintenance worker operates the button T3, the numeric keypad T5, etc. while observing the test pattern TP ′ together with the actual test pattern TP, thereby correcting trapezoidal distortion, LED brightness, white color temperature, brightness, contrast, and gamma value. These settings can be changed by directly inputting numerical values. At this time, the overall shape or color tone of the test pattern TP ′ changes according to the operation of the maintenance worker. The values of various items such as trapezoidal distortion correction, LED brightness, white color temperature, brightness, contrast, and gamma value that have been changed in this way are the projector setting value storage area of the SRAM 401 of the sub control board SS and the sub RAM board 41. Is set in the projector setting value storage area.

  Next, a modified example of the present invention will be described. Note that the same or similar components as those according to the above-described embodiment are denoted by the same reference numerals and description thereof is omitted.

Such a heat sink 243Xc with the fin portion exposed to the outside can also effectively eliminate the accumulation of heat inside the projector apparatus X and prevent overheating of optical components such as lenses.

  FIG. 127 shows an arrangement of projector apparatuses according to the third modification. The projector apparatus X ″ shown in the figure does not have a detailed structure, but employs the same structure as the projector apparatus X ′ shown in FIG. 126 described above except that a heat sink exposed to the outside is not provided. That is, in the projector apparatus X ″, a heat radiating plate 2430 is provided so as to face the opening X22C of the cover case X22 instead of the heat sink 243Xc described above, and the upper surface of the heat radiating plate 2430 is slightly protruded from the opening X22C. It is exposed (not shown in FIG. 127).
