A front door 112 is provided. The housing 111 houses a reel unit 130 in which a rotatable first reel 131, a second reel 132, and a third reel 133 are unitized, a hopper device for dispensing medals, and the like. Further, the front door 112 is divided into an upper door 112a and a lower door 112b, and each of the upper door 112a and the lower door 112b can be opened and closed with respect to the housing 111.

The upper door 112a is provided with a liquid crystal display 113, a speaker 114, and other performance devices, and a display window 115. On the liquid crystal display 113, images for various effects (videos, still images) are displayed. The speaker 114 outputs various effects sounds (music, sound effects, voices, etc.). In addition to the liquid crystal display 113 and the speaker 114, the display device may include an illumination device such as a lamp (LED), a movable accessory that can be operated by an actuator, etc.

At the back of the display window 115, the reel unit 130 is arranged so that a part of the reel unit 130 is visible from outside the display window 115. On the outer peripheral surfaces of the first reel 131, second reel 132, and third reel 133, a plurality of types of symbols are arranged in a line along the circumferential direction, and when each reel 131, 132, 133 stops, a display is displayed. Three consecutive symbols are displayed per reel through the window 115. In addition, the display window 115 is provided with an upper stage, a middle stage, and a lower stage as display positions for visually recognizing the symbols of each reel 131, 132, 133. A valid line is set. In the gaming machine of this embodiment, the active line is constituted by the middle stage of the first reel 131, the middle stage of the second reel 132, and the middle stage of the third reel 133. In addition, in the gaming machine of this embodiment, the number of medals required for one game (regular number) is set to 3, and when the specified number of medals is inserted, the active line is activated. It is now possible to do so.

In the slot machine 100, each reel 131, 132, 133 starts rotating with the start of the game, and a winning combination lottery is executed to determine whether one of the winning combinations is won or lost. Next, when each reel 131, 132, 133 stops, if a symbol combination corresponding to a winning combination won in the winning combination lottery is displayed on the active line, this winning combination becomes a prize, and the winning combination corresponds to the won winning combination. The process (winning process) is executed.

The lower door 112b includes a rotating medal slot 121 for inserting medals, a MAX bet button (bet button) 122 for betting credited medals, and a rotating start lever 123 that is operated when starting a game. A stop button 124 for stopping each reel 131, 132, 133, a payout port 125 for paying out medals by a hopper device, a medal receiving tray 126 for receiving medals paid out from the payout port 125, and the like are provided. Furthermore, a medal sensor is provided at the back of the medal slot 121 to detect passage of medals inserted from the medal slot 121. Further, a production button 128 is provided on the lower door 112b. The production button 128 includes, for example, a push switch and a rotary switch (jog dial), and is configured to be able to be pressed and rotated. When the performance button 128 is operated, the mode of performance changes, thereby increasing the interest of the game.

In the slot machine 100, the operation of the start lever 123 is enabled when medals are inserted into the medal slot 121 or when the MAX bet button 122 is operated and a prescribed number of medals are bet. Further, when the activated start lever 123 is operated, the game is started. When the game starts, each reel 131, 132, 133 starts rotating, and when the rotation speed of each reel 131, 132, 133 reaches a constant speed and becomes steady rotation, the operation of the stop button 124 is activated. Ru. Further, when the enabled stop button 124 is operated, each reel 131, 132, 133 corresponding to the operated stop button 124 stops.

Inside the slot machine 100, a main control board (main board) and a sub-control board (sub board) are provided. The main control board receives input signals from input means such as the MAX bet button 122, the start lever 123, the stop button 124, and the medal sensor, performs various calculations to execute the game, and based on the calculation results, the reel unit 130 and output means such as a hopper device. In addition, the sub-control board receives signals sent from the main control board, performs various calculations to execute the performance, and controls the display devices such as the liquid crystal display 113 and the speaker 114 based on the calculation results. I do.

In addition, the main control board and the sub-control board are electrically connected, and it is possible to send various information (signals) such as information indicating the gaming status from the main control board to the sub-control board. Information cannot be sent from the control board to the main control board. In addition, the functions of each board such as the main control board and sub-control board are stored in advance in hardware such as various processors (CPU, DSP, etc.), ICs, or information storage media such as ROM and RAM, ROM, etc. This is realized by software consisting of a predetermined program.

A design member 150 having a plurality of symbol parts (eg, symbol part 101, symbol part 102, symbol part 103, symbol part 104, and symbol part 105: see FIG. 2) is provided on the left side of the upper door 112a. However, the position where the design member 150 is provided is not limited to this position, and may be any position on the front door 112. For example, the design member 150 may be provided above the liquid crystal display 113 (top lens).

In this embodiment, symbol portions 101 to 105 protrude toward the front side (player side). In addition, identification information is expressed by the shape of the front surface (tip surface) of each of the symbol portions 101 to 105. Identification information includes characters, figures, symbols, and the like. Hereinafter, in this embodiment, one symbol part represents one character, but for example, one symbol part represents two or more characters, or a combination of a character and a symbol. It may also represent something.

FIG. 2 is a front view of a portion where the design member 150 is provided.
Symbol sections 101 to 105 are a series of broadcast information (character strings). In this embodiment, the symbol parts 101 to 105 form a series of notification information such as "The main character is ○○"("○○" represents the name of the character, etc.). Specifically, the shape of the tip end face of the symbol portion 101 represents one character "main". Furthermore, the shape of the tip end face of the symbol portion 102 represents one character, ``Waku''. Further, the shape of the tip end face of the symbol portion 103 represents one character “ha”. Further, the shape of the tip end face of the symbol portion 104 represents one character “◯”. Further, the shape of the tip end face of the symbol portion 105 represents one character “◯”.

The symbol portions 101 to 103 are provided so as to be lined up in the left-right direction. Further, below the symbol parts 101 to 103, a symbol part 104 and a symbol part 105 are provided so as to be vertically arranged in this order.
The symbol sections 101 to 105 include identification information (characters) of different sizes. Specifically, the character size of the symbol portion 103 is formed to be the smallest, and the character size of the symbol portion 104 is formed to be the largest. Further, the symbol parts 101 and 102 have the same font size, and are formed so that the font size is larger than the symbol part 103 and smaller than the symbol parts 104 and 105. Further, the character size of the symbol portion 105 is formed to be larger than the symbol portions 101 to 103 and smaller than the symbol portion 104. That is, the font size increases in the order of (1) symbol portion 103, (2) symbol portions 101 and 102, (3) symbol portion 105, and (4) symbol portion 104.

FIG. 3 is a schematic diagram showing a part of the upper door 112a seen from the left. The design member 150 has a base surface 151 that serves as a reference surface for protruding the symbol portions 101 to 105. This base surface 151 is a surface perpendicular to the front-rear direction. The symbol portions 101 to 105 are formed such that their respective tip surfaces (front surfaces) protrude forward from the base surface 151. Hereinafter, the amount of protrusion refers to the amount of protrusion of the symbol portions 101 to 105 from the base surface 151.
At this time, the protrusion amount L3 of the symbol portion 103 is formed to be the smallest, and the protrusion amount L4 of the symbol portion 104 is formed to be the largest. Further, the protrusion amounts L1 and L2 of the symbol portions 101 and 102 are formed to be larger than the protrusion amount L3 of the symbol portion 103 and smaller than the protrusion amounts L4 and L5 of the symbol portions 104 and 105. Further, the protrusion amount L5 of the symbol portion 105 is larger than the protrusion amounts L1 to L3 of the symbol portions 101 to 103, and smaller than the protrusion amount L4 of the symbol portion 104. That is, the protrusion amount increases in the order of (1) symbol section 103, (2) symbol sections 101 and 102, (3) symbol section 105, and (4) symbol section 104.
In this way, the symbol portions 101 to 105 are formed to have different character sizes and to have different protrusion amounts depending on the character size. Specifically, symbol portions 101 to 105 are formed such that the larger the size of the character (identification information), the larger the amount of protrusion. This creates a three-dimensional visual effect, making the characters (identification information) more three-dimensionally visible, attracting the player, giving a novel impression, and improving the interest of the game. Specifically, in addition to the difference in the size of the letters (identification information), the amount of protrusion toward the player also differs, so the difference in the degree of emphasis between large and small letters becomes larger, making them even more attractive to players. . As in this example, if the larger the font size, the larger the amount of protrusion, the larger font will seem to come closer to the player, which will attract the player.

Note that in this embodiment, the symbol parts 101 to 105 and the base surface 151 are integrated (one member), but the symbol parts 101 to 105 and the base surface 151 are separate parts (separate members). ). Further, the base surface 151 of the symbol parts 101 to 105 forming a series of broadcast information is not limited to one member, but may be composed of a plurality of members. In other words, the base surface 151 may be a single piece or a plurality of pieces. Furthermore, when the base surface 151 is composed of a plurality of base surfaces, the positions of the base surface of a predetermined symbol section and the base surface of another symbol section different from the predetermined symbol section in a predetermined direction (for example, the front-back direction) are different. It's okay. Specifically, in FIG. 3, for example, a base surface 151 (referred to as a first base surface) of symbol portions 101 to 103 and a base surface 151 (referred to as a second base surface) of symbol portions 104 to 105 are provided, respectively. In that case, the positions of the first base surface and the second base surface in the front-rear direction may be different. For example, the position of the second base surface may be approximately 1 to 2 mm forward or rearward of the position of the first base surface in the front-rear direction.

Furthermore, in this embodiment, the symbol parts 101 to 105 are formed so that the larger the size of the characters (identification information), the larger the amount of protrusion. It may be formed so that the amount of protrusion is small. That is, in FIG. 3, the protrusion amount may be increased in the order of (1) symbol section 104, (2) symbol section 105, (3) symbol sections 101 and 102, and (4) symbol section 103. Even in this case, a three-dimensional visual effect is produced, and the characters (identification information) are more three-dimensionally visible, attracting the player, giving a novel impression, and improving the interest of the game. In this case, the degree of cooperation differs depending on the size of the characters (identification information), and the smaller characters protrude more, so the smaller characters are closer to the front (towards the player) than the larger characters. Both large and small fonts attract players.
Furthermore, at least a portion of the plurality of symbols constituting a series of broadcast information is configured such that the amount of protrusion becomes larger in stages or the amount of protrusion becomes smaller in stages as the size of the identification information becomes larger. Good too.

In addition, if the identification information with the largest size among a series of broadcast information is formed with the largest or smallest protrusion amount, other identification information with a different size from the relevant identification information (The size of the identification information is other than the maximum) may have the same (same or substantially the same) protrusion amount.
In this case, the largest font size (identification information) is located in front of other identification information (on the player's side), or the largest font (identification information) is located ahead of other identification information. Since it is located on the rear side and is visible, a three-dimensional visual effect is generated and attracts players.

Further, in this embodiment, the tip surfaces of the symbol portions 101 to 105 are perpendicular to the front-rear direction (flat surface); however, the tip surfaces of the symbol portions 101 to 105 may be inclined surfaces, curved surfaces, uneven It may be a shape having. Note that when the tip surfaces of the symbol portions 101 to 105 have a shape other than a flat surface, the amount of protrusion of the symbol portions 101 to 105 is measured at the most forward position (the most protruding position) (the topmost portion) on the tip surface. shall be taken as a thing.

FIG. 4 is a schematic diagram showing a part of the upper door 112a seen from the left, and the tip surfaces of each of the symbol parts 101 to 105 are sloped surfaces that protrude forward as they move upward in the vertical direction. A modified example is shown. The font size increases in the order of (1) symbol section 103, (2) symbol sections 101 and 102, (3) symbol section 105, and (4) symbol section 104. Further, the protrusion amount increases in the order of (1) symbol portion 103, (2) symbol portions 101 and 102, (3) symbol portion 105, and (4) symbol portion 104.
In this way, even when the tip surfaces of the symbol portions 101 to 105 are inclined surfaces, the larger the character size, the larger the amount of protrusion. This makes the characters more three-dimensionally visible and increases the interest of the game.
Note that in FIG. 4, in the relationship between the symbol portion 104 and the symbol portion 105, it is assumed that the amount of protrusion of the minimum protrusion on the front surface of the symbol portion 104 is smaller than the amount of protrusion of the topmost portion of the symbol portion 105; However, the present invention is not limited to this, and the minimum protruding portion of the symbol portion 104 may protrude further forward than the highest portion of the symbol portion 105.
Further, the inclination angle of the tip surface (slanted surface) with respect to the base surface 151 may be changed depending on the font size of the symbol portions 101 to 105. For example, the larger the font size, the larger the inclination angle of the tip surface. Further, the tip surfaces of the symbol portions 101 to 105 may be inclined in different directions.

Further, in this embodiment, the symbol parts 101 to 105 of the design member 150 are exposed, but the design member 150 has a translucent material that covers the periphery (front and side) of the symbol parts 101 to 105. (transparent resin) cover (not shown), and inside the cover, the character sizes and protrusion amounts of the symbol parts 101 to 105 may be configured to have the above-mentioned relationship. good. The cover is fixed to the upper door 112a by, for example, screwing. In this case, the symbol parts 101 to 105 can be viewed three-dimensionally through the cover, improving the interest of the game. Further, by providing the cover, each symbol portion can be protected from damage.

Further, the symbol parts 101 to 103 are formed of a non-transparent resin, and the symbol part 104 and the symbol part 105 are formed of a transparent resin. ) may be provided. In this case, the symbol portion 104 and the symbol portion 105 emit light due to the light emitted from the light emitter. In this way, the larger the size of the letters, the larger the amount of protrusion, and by configuring the large letters so that they can be illuminated, the game becomes more interesting. Note that the symbol parts 101 to 103 may also be made of a transparent resin, and an LED board may be provided on the back side of the symbol parts so that they can be illuminated. Furthermore, for example, the illumination brightness and emitted light color may be changed depending on the font size of each symbol portion.

Further, in this embodiment, the base surface 151 is a surface perpendicular to the front-rear direction, but the present invention is not limited to this, and the base surface 151 may be an inclined surface of the front door 112. For example, the base surface 151 may be the inclined surface F on which the MAX bet button 122 and the production button 128 on the lower door 112b shown in FIG. 1 are provided. This inclined surface F is inclined downward toward the front in the front-rear direction. If this inclined surface F is used as the base surface 151, the symbol parts 101 to 105 will protrude in a direction perpendicular to the inclined surface F.

Further, the design member 150 may be provided on a pressing portion of a button (for example, the MAX bet button 122, the production button 128, etc.). The pressing portion is a member that is made of resin or the like, is supported by a biasing member such as a spring, and can be pushed. In this case, the pressing portion has a base surface 151 that is, for example, a surface perpendicular or substantially perpendicular to the operation direction (pressing direction), and the symbol portion is formed on this base surface 151. The symbol portion protrudes in a direction perpendicular to the base surface 151.

Here, an example in which the design member 150 is provided on the pressing portion of the MAX bet button 122 will be described. In this case, for example, six symbol parts are provided, and the shape of the top surface (top surface) of the first symbol part is the letter "M", and the shape of the top surface (top surface) of the second symbol part is the letter "A". , the shape of the tip surface (top surface) of the third symbol section is the letter "X", the shape of the tip surface (top surface) of the fourth symbol section is the letter "B", and the shape of the tip surface (top surface) of the fifth symbol section is the letter "X". ) is the letter "E", and the tip surface (upper surface) of the sixth symbol part is the letter "T". Then, the first to third symbol parts are arranged in this order in the left-right direction to form an upper stage, and the fourth to sixth symbol parts are arranged in this order in the left-right direction to form a lower stage, so that they are arranged in two stages.

At this time, the font size of the first to third symbol portions (MAX) is formed larger than the font size of the fourth to sixth symbol portions (BET). Note that the font sizes of the first to third symbol parts are the same, and the font sizes of the fourth to sixth symbol parts are the same. Further, the amount of protrusion of the first to third symbol portions (MAX) is formed to be larger than the amount of protrusion of the fourth to sixth symbol portions (BET). As a result, the first to sixth symbol portions can be viewed more three-dimensionally, improving the interest of the game.
In addition, in order to prevent each symbol from being directly exposed, a translucent (transparent resin) cover is provided to cover the periphery (top and side surfaces) of each symbol, so that each symbol can be seen through the cover. You can do it like this. The cover is fixed to the pressing part by, for example, adhesive. By providing the cover, each symbol part can be protected from damage, etc., and since the symbol part does not come into direct contact with the finger when operating the pressing part, the player can operate it comfortably.

Next, an example in which the design member 150 is provided on the pressing portion of the effect button 128 will be described. In this case, for example, four symbol parts are provided, and the shape of the top surface (top surface) of the first symbol part is the letter "P", and the shape of the top surface (top surface) of the second symbol part is the letter "U". , the shape of the tip end surface (top surface) of the third symbol part is the letter "S", and the shape of the tip surface (top surface) of the fourth symbol part is the letter "H". The first to fourth symbol portions are arranged in this order, for example, so as to be lined up in the left-right direction (lined up horizontally).

At this time, the first to fourth symbol parts (PUSH) are formed such that, for example, the character size gradually decreases from both ends toward the center. Further, the first to fourth symbol portions are formed such that the amount of protrusion gradually decreases from both ends toward the center. In other words, the font size and the amount of font protrusion gradually increase from the inside to the outside in the left-right direction. As a result, the first to fourth symbol portions can be viewed more three-dimensionally, improving the interest of the game. In order to prevent the first to fourth symbol parts from being directly exposed, a translucent (transparent resin) cover is provided to cover the first to fourth symbol parts, and the first to fourth symbol parts are exposed through the cover. The 4-symbol portion may be visually recognized. Further, the first to fourth symbol portions may be configured such that large characters and small characters alternate, for example, so that the amount of protrusion of the large characters is greater than the amount of protrusion of the small characters.

Next, the design member 38 will be explained. The design member 38 includes a plurality of symbol parts (for example, a symbol part 101, a symbol part 102, a symbol part 103, and a symbol part 104). In the symbol parts 101 to 104, characters (identification information) are represented by the shape of the respective tip surfaces. In this embodiment, one character "Minami" is represented by the shape of the tip end face of the symbol portion 101. Furthermore, the shape of the tip end face of the symbol portion 102 represents one character "Kuni". Further, the shape of the tip end face of the symbol portion 103 represents one character “Otsu”. Further, the shape of the tip end face of the symbol portion 104 represents one character "woman". The symbol parts 101 to 104 constitute a series of character strings "Tropical Maiden". The symbol parts 101 and 102 are provided so as to be lined up in the left-right direction, and between the symbol part 101 and the symbol part 102, the symbol parts 103 and 104 are provided so as to be lined up in this order in the vertical direction.

FIG. 7 is a front view of the design member 38. Comparing the sizes of the identification information (characters) in the symbol parts 101 to 104, the symbol parts 101 and 102 have the same character size, and are formed so that the character size is the smallest. Further, the symbol portion 104 is formed so that the font size is the largest. Further, the symbol portion 103 is formed so that the character size is larger than the symbol portions 101 and 102 and smaller than the symbol portion 104. That is, the font size increases in the order of (1) symbol portions 101 and 102, (2) symbol portion 103, and (3) symbol portion 104.

8 is a schematic side view seen from the P direction shown in FIG. 7, and FIG. 9 is a schematic side view seen from the Q direction shown in FIG. 7.
The design member 38 has a base surface 38a that serves as a reference surface for protruding the symbol parts 101 to 104. In this embodiment, the base surface 38a is a surface perpendicular to the front-rear direction. The symbol portions 101 to 104 are formed such that their respective tip surfaces (front surfaces) protrude forward from the base surface 38a. Hereinafter, the amount of protrusion refers to the amount of protrusion of the symbol portions 101 to 104 from the base surface 38a.
Comparing the protrusion amounts of the symbol portions 101 to 104 with reference to FIGS. 8 and 9, it is found that the protrusion amounts L1 and L2 of the symbol portions 101 and 102 are the smallest, and the protrusion amount L4 of the symbol portion 104 is the largest. . Further, the protrusion amount L3 of the symbol portion 103 is larger than the protrusion amounts L1 and L2 of the symbol portions 101 and 102, and smaller than the protrusion amount L4 of the symbol portion 104. That is, the protrusion amount increases in the order of (1) symbol parts 101 and 102, (2) symbol part 103, and (3) symbol part 104. In this way, the symbol parts 101 to 104 are formed such that the larger the character size, the larger the amount of protrusion. This creates a three-dimensional visual effect, making the characters more three-dimensionally visible, attracting the player, giving a novel impression, and increasing the interest of the game.

In this embodiment, the tip surfaces of the symbol parts 101 to 104 are perpendicular to the front-rear direction (flat surface); however, the front surfaces of the symbol parts 101 to 104 may have an inclined surface, a curved surface, or an uneven surface. It may be a shape or the like. When the front surfaces of the symbol portions 101 to 104 are shaped other than flat in this way, the amount of protrusion of the symbol portions 101 to 104 is measured at the most forward position (top) on the tip surface. Further, in the present embodiment, the base surface 38a is a surface perpendicular to the front-rear direction, but the base surface 38a is, for example, a surface inclined with respect to the front-rear direction, and the symbol portion 101 is arranged in a direction perpendicular to the slope. ~104 may be made to protrude.

Further, in this embodiment, the front sides of the symbol parts 101 to 104 (design member 38) are covered with the glass unit 8 (see FIG. 5). may be provided on the front frame 10 (see FIG. 5) and configured to be exposed. Furthermore, some or all of the symbol sections 101 to 104 may be configured to be illuminated, and furthermore, the illumination brightness and emitted light color may be changed depending on, for example, the font size of each symbol section.

Further, the design member 38 may be provided on the pressing portion of the effect operation device 26 (see FIG. 5). In this case, for example, four symbol parts are provided, and the shape of the top surface (top surface) of the first symbol part is the letter "P", and the shape of the top surface (top surface) of the second symbol part is the letter "U". , the shape of the tip end surface (top surface) of the third symbol part is the letter "S", and the shape of the tip surface (top surface) of the fourth symbol part is the letter "H". Then, the first to fourth symbol parts are arranged in this order, for example, in the left-right direction (in a row horizontally).

At this time, the first to fourth symbol portions are formed such that, for example, the character size gradually decreases from both ends toward the center. Further, the first to fourth symbol portions are formed such that the amount of protrusion gradually decreases from both ends toward the center. In addition, in order to prevent the first to fourth symbol parts from being directly exposed, a translucent (transparent resin) cover is provided to cover the periphery of the first to fourth symbol parts, and the first to fourth symbol parts are exposed through the cover. The 4-symbol portion may be visually recognized. With this configuration, the first to fourth symbol portions in the effect operation device 26 can be viewed more three-dimensionally, improving the interest of the game.

Next, the sub-board unit 200 will be explained.
FIG. 10A is a diagram (plan view) of the sub-board unit 200 seen from the back side. FIG. 10(b) is a schematic cross-sectional view taken along line AA shown in FIG. 10(a). Further, FIG. 11 is a diagram (plan view) of the sub-board 210 viewed from the back side. Note that FIG. 11 shows a state in which the sub-board case 220 is removed in FIG. 10(a).
The sub-board unit 200 is provided on the back side of the liquid crystal display 113 (see FIG. 1) according to the first embodiment and the liquid crystal display 32 (see FIG. 6) according to the second embodiment. Although the sub-board unit 200 will be described below, the specifications shown in FIG. 10 can be applied to liquid crystal board units, LED board units, and power supply board units other than the main board unit.

As shown in FIGS. 10A and 10B, the sub-board unit 200 includes a sub-board 210, a sub-board case 220 that covers the back side of the sub-board 210, and the like. This sub-board case 220 is made of, for example, transparent resin, and has a substantially concave cross section in the vertical direction.
Further, as shown in FIG. 11, electronic components are mounted (arranged) on the sub-board 210. In this example, an IC 217 and a resistor 218 are mounted as electronic components. Although not shown, capacitors and the like are also mounted on the sub-board 210 as electronic components.
As shown in FIG. 10(a), the sub-board case 220 is provided with a plurality of through holes 221 that penetrate in the front-rear direction. The plurality of through holes 221 include a small diameter through hole 222 and a large diameter through hole 223. The small-diameter through hole 222 is provided inside the sub-board case 220 (on the center side). On the other hand, the large-diameter through hole 223 is provided on the outside (outer peripheral end side) of the sub-board case 220. The large-diameter through-hole 223 is mainly provided at a position facing a location (range) on the sub-board 210 where no electronic components (such as chips) are arranged. Note that a large diameter through hole 223 may be provided at a position facing the capacitor.
Furthermore, in the sub-board case 220, there are places where small-diameter through-holes 222 are provided at positions facing the IC 217 among the electronic components, but there are no places where large-diameter through-holes 223 are provided. Note that FIG. 10A shows an example of how to provide the small-diameter through-holes 222 and the large-diameter through-holes 223, and the number of holes is not limited to this.

As shown in FIG. 10(b), the small diameter through hole 222 is formed in a tapered shape so that the hole diameter gradually decreases from the front side (board side) to the rear side (housing side). The small diameter through hole 222 has a smallest hole diameter (inner diameter) of about 2 mm and a largest hole diameter (outer diameter) of about 3 mm. Further, the distance between the centers of two holes adjacent in the left and right direction is approximately 5 mm (see FIG. 10(a)).
As shown in FIG. 10(b), the large diameter through hole 223 is formed in a reverse tapered shape so that the hole diameter gradually increases from the front side (board side) to the rear side (housing side). The large diameter through hole 223 has a smallest hole diameter (inner diameter) of about 2 mm and a largest hole diameter (outer diameter) of about 4 mm. Further, the distance between the centers of two holes adjacent in the left and right direction is approximately 6 mm (see FIG. 10(a)). Note that the smallest hole diameter (inner diameter) of the large diameter through hole 223 may be about 2.5 mm, which is larger than about 2 mm.

The small-diameter through-hole 222 has a tapered shape in which the hole diameter gradually decreases from the front side toward the rear side. Therefore, air inside the sub-board case 220 is easily released to the outside through the small-diameter through-hole 222. Further, the small diameter through hole 222 is sometimes provided at a position facing the IC on the board, and by making it tapered, it also serves as a measure to prevent unauthorized insertion of instruments etc. from the rear side (back side).
The large-diameter through-hole 223 has a reverse tapered shape in which the hole diameter gradually increases from the front side toward the rear side. Therefore, air outside the sub-board case 220 is easily drawn into the sub-board case 220 through the large-diameter through hole 223.

Next, the volume adjustment switch 300 will be explained. As shown in FIG. 11, the volume adjustment switch 300 is arranged on the sub-board 210 and electrically connected to the sub-board 210. This volume adjustment switch 300 adjusts the volume (volume) of the sound output from the speaker 114 according to the first embodiment (see FIG. 1), the speaker 14 according to the second embodiment (see FIG. 5), etc. ) is provided to adjust. Note that although the following description will be made using the volume adjustment switch 300, the present content can be applied to predetermined adjustment switches (rotary switches) including the volume adjustment switch 300. The predetermined adjustment switch includes the volume adjustment switch 300, the brightness adjustment switch, the production changeover switch, and the like. The brightness adjustment switch is provided to make it possible to adjust the luminance (brightness) of the lighting device (illumination device) of the gaming machine. Further, the performance changeover switch is provided to enable settings related to the performance to be changed on the hall (gaming hall) side. For settings related to presentation, for example, if four types of states (four types of presentation states) with different presentation contents are prepared, one state can be selected from among the four states. Note that the four states may include, for example, a state in which a specific effect appears and a state in which a specific effect does not appear.

12(a) is a view (plan view) of the volume adjustment switch 300 seen from the back side, and FIG. 12(b) is a view (plan view) of the housing 310 of the volume adjustment switch 300 seen from the back side. . Further, FIG. 13 is a schematic cross-sectional view taken along the line BB shown in FIG. 10(a). Note that the housing 310 is not shown in cross section in FIG. Moreover, FIG. 14 is a perspective view of the volume adjustment switch 300 seen from the back side.

As shown in FIG. 13, the volume adjustment switch 300 includes a housing 310, a shaft member 320, a knob 330, and the like. As shown in FIG. 12(b), the housing 310 has a square shape in plan view (rectangular shape in plan view). Planar view refers to viewing the surface of the sub-board 210 on the side where the volume adjustment switch 300 is arranged from a direction perpendicular to the surface. Housing 310 is fixed to sub-board 210 by, for example, soldering. A hole 311 having a circular shape in plan view is provided in a surface (upper surface) 310a of the housing 310 opposite to the substrate side. A shaft member 320 (see FIG. 13) projects from this hole 311. The shaft member 320 has its proximal end housed inside the housing 310, and is rotatable around the axis. As the shaft member 320 rotates, for example, a rotor (not shown) inside the housing 310 rotates.

As shown in FIG. 12(b), a level display section 312 is provided on the upper surface 310a of the housing 310 so as to surround the hole 311. This level display section (predetermined display) 312 is formed by, for example, numbers 0 to 9 indicating the volume (level) of the volume being attached at predetermined intervals in a ring shape. Each number is arranged so that the bottom of the number faces the center of the hole 311 (the center of a knob 330, which will be described later). Note that in this embodiment, the predetermined display is a number indicating the volume (level), but it may be a letter or symbol other than the number. In the case of a brightness adjustment switch, as a predetermined display, for example, numbers indicating the brightness (brightness) in stages are attached in a ring shape. Further, in the case of a performance changeover switch, as a predetermined display, for example, numbers and letters (for example, alphabets) corresponding to each performance state are attached in a ring shape. Here, the diameter of a circle (a circumscribed circle connecting the upper parts of each number) regulating the outer peripheral side (radially outer side) of the range of the level display section 312 is defined as the level diameter 313.

As shown in FIG. 13, the knob 330 has a cylindrical shape with one end closed and the other end open. The knob 330 has an inner diameter that allows it to be placed over the shaft member 320. When the knob 330 is rotated with the knob 330 placed over the shaft member 320, the shaft member 320 rotates in synchronization with the knob 330. Further, at the end of the knob 330 on the opening side (housing 310 side), a flange-shaped flange portion 331 that protrudes radially outward is provided. The knob 330 is made of, for example, transparent resin or black resin.
In addition, in the above description, the case where the shaft member 320 and the knob 330 are separate bodies has been described, but the shaft member 320 and the knob 330 may be integrally configured. In other words, when referring to the knob 330, the shaft member 320 may be included. It can be said that the knob 330 is rotatably supported by the housing 310. Further, the upper surface 310a of the housing 310 can be said to be the surface of the housing 310 on the knob 330 side.

As shown in FIG. 12(a), the collar portion 331 is provided in an annular shape (circular shape in plan view) when viewed from the axial direction of the knob 330, and is provided at one location in a U-shape when viewed from the axial direction. A notch 331a is formed. This notch portion 331a is formed in a size that allows one number (level) of the level display portion 312 to be visually recognized.

Although not shown in FIG. 13, a slight gap of less than 1.0 mm is provided between the bottom surface of the collar portion 331 and the top surface 310a of the housing 310. For this reason, the level display portion 312 printed on the upper surface 310a of the housing 310 is not scratched and the level display (numbers) does not become unclear. In other words, deterioration in the visibility of the level display can be prevented. In addition, since the gap is small, less than 1.0 mm, when the knob 330 is set at the appropriate position (when the level is located approximately in the middle of the notch 331a), the axial direction of the knob 330 Whether viewed from the front or obliquely with respect to the axial direction, the level display next to the level display (number) located inside the notch 331a is not visible. That is, two level displays are not visually recognized at the same time, and the current setting value can be accurately grasped.

Further, as shown in FIG. 15, the width at the upper part (radially outer side) of the notch 331a is defined as the width X, and the width between the centers of adjacent levels (numbers) is defined as the width Y. The width X is less than or equal to the width Y. Therefore, if the notch 331a is located between the center of one number (for example, "1") and the center of the other number (for example, "0"), both numbers (here, "1" and "0") are unrecognizable or difficult to recognize. Thereby, it is possible to more easily recognize a setting error of the knob 330, that is, the knob 330 is not rotated to an appropriate position (the knob 330 is in an inappropriate position).

Further, as shown in FIG. 14, a plurality of longitudinal grooves 332 are provided on the outer peripheral surface of the knob 330 along the axial direction at predetermined intervals along the circumferential direction. By providing a plurality of vertical grooves 332, it is possible to prevent fingers from slipping when rotating the knob 330. Moreover, one horizontal groove 333 is formed on the tip end surface of the knob 330 along a diameter passing through the center. By inserting a flathead screwdriver or the like into this lateral groove 333 and rotating it, the knob 330 can be rotated without having to pinch it directly.

Further, as shown in FIG. 13, a case opening (opening) 224 is provided in the sub-board case (board case) 220 located on the back side (upper side in FIG. 13) of the volume adjustment switch 300. This case opening 224 has a circular shape in plan view (concentric with the knob 330). This case opening 224 is provided at a position corresponding to (opposed to) the position of the knob 330 in order to allow the tip of the knob 330 to protrude (to allow the knob 330 to be inserted therethrough). By rotating a knob 330 protruding from the case opening 224, the loudness (volume) of the sound output from the speaker can be adjusted. For example, if the knob 330 is rotated to increase the number visible through the notch 331a, the volume output from the speaker will increase. Note that the sub-board case 220 is made of, for example, transparent resin. This is to enable the components housed (arranged) inside the sub-board case 220 to be visually recognized.

In this embodiment, the sub-board case 220 has a concave portion 225 that is recessed one step from the back side (top side) toward the substrate side. Case opening 224 is provided approximately at the center of recess 225 . By making the knob 330 protrude inside the recess 225 in this way, it becomes difficult for fingers or the like to come into contact with the knob 330, and it is possible to prevent the knob 330 from rotating due to erroneous contact or the like.

Components arranged (connected) on the sub-board 210 include electronic components, connectors, and a volume adjustment switch 300. ) stands out. Furthermore, the sub-board case 220 is formed to have a concave cross-section so as to cover the sub-board 210 from the back side. The top surface 226a of the back plate portion 226 in the sub-board case 220 is formed to be located further back (on the upper side) than the tip of the volume adjustment switch 300. In other words, the tip of the volume adjustment switch 300 (knob 330) does not protrude beyond the top surface 226a of the sub-board case 220. Note that the protrusion of the knob 330 from the case opening 224 is such that it can be pinched with, for example, fingers.

During the assembly process, the sub-board unit 200 may be placed on a stand or the like with the sub-board case 220 side facing down, but even in that case, the knob 330 is lower than the top surface 226a of the sub-board case 220. Since it does not protrude, no impact is applied to the volume adjustment switch 300. This can prevent damage to the volume adjustment switch 300 due to force (impact) being applied to the tip of the volume adjustment switch 300 when placed on a stand or the like.
In FIG. 13, the top surface 226a of the sub-board case 220 is positioned on the back side (top side) of the tip of the volume adjustment switch 300, and the recess 225 is provided. If the structure is such that no impact is applied, the recess 225 does not necessarily need to be provided. In that case, a case opening 224 may be provided in the back plate portion 226.

Further, as shown in FIG. 13, the length L is the gap between the upper surface of the collar portion 331 and the substrate-side (inside) surface of the sub-board case 220. This length L is approximately 1 to 2 mm. The length L is made narrow from the viewpoint of fraud prevention, and is set to such a length that the flange portion 331 and the sub-board case 220 do not interfere even if the component tolerance becomes the worst. By reducing this length L, fraud can be prevented.

FIG. 31(a) is a diagram of another sub-board unit 600 viewed from the back side. FIG. 31(b) is a schematic cross-sectional view taken along the line VV shown in FIG. 31(a). On the sub-board 210, electronic components (not shown) such as a capacitor and a resistor, a volume adjustment switch 300, a connector CN, a dip switch DIP, etc. are arranged. Here, the position (height) of the top surface 226a of the sub-board case 220 is determined according to tall electronic components (for example, capacitors) placed on the sub-board 210, but switches, connectors, etc. Since it is necessary to expose these areas, a recess 225 is provided and an opening is formed in the recess 225. At this time, the tip of the switch or connector that protrudes from the opening of the recess 225 is designed not to protrude beyond the top surface 226a of the sub-board case 220. Note that the tip of the volume adjustment switch 300 (knob 330) protrudes further toward the top surface 226a than the tip of the connector CN.

During the assembly process, etc., the sub-board unit 600 may be placed on a stand, etc. with the sub-board case 220 side facing down, but even in that case, the switches (including the volume adjustment switch 300) and connector CN may be Since it does not protrude beyond the top surface 226a of the sub-board case 220, no impact is applied to the switch or connector CN. This can prevent the volume adjustment switch 300 and the connector CN from being damaged due to force (impact) being applied to the tips of the volume adjustment switch 300 and the connector CN when placed on a table or the like.

FIG. 32(a) is an enlarged view of section P in FIG. 31(a). FIG. 32(b) is a schematic cross-sectional view taken along the line WW shown in FIG. 32(a). Hereinafter, the dimension of one side of the housing 310 (upper surface 310a) will be referred to as the length of one side of the housing 310 (one side length). Further, the diagonal dimension of the housing 310 (upper surface 310a) is referred to as the diagonal length of the housing 310 (diagonal length). The diagonal length of the housing 310 is longer than the length of one side of the housing 310.

The diagonal length of the housing 310 is greater than or equal to the diameter of the case opening 224 (the diagonal length of the housing 310 is greater than the diameter of the case opening 224). For example, if excessive force (load) is applied to the knob 330 or if the fixation (adhesion) of the volume adjustment switch 300 to the sub-board 210 deteriorates over time, the volume adjustment switch 300 may be removed from the sub-board 210. This is a case where damage occurs that causes it to come off. Even in such a case, since the diagonal length of the housing 310 is greater than or equal to the diameter of the case opening 224, the housing 310 will be caught in the case opening 224. Therefore, the volume adjustment switch 300 can be prevented from popping out (being ejected) from the sub-board case 220 through the case opening 224. Thereby, the volume adjustment switch 300 discharged to the outside of the sub-board case 220 can be prevented from being lost. Further, the volume adjustment switch 300 discharged to the outside of the sub-board case 220 can be prevented from affecting other components. Note that the length of one side of the housing 310 may be greater than or equal to the diameter of the case opening 224.

Further, the length of one side of the housing 310 is greater than or equal to the diameter of the flange 331 (the length of one side of the housing 310 is larger than the diameter of the flange 331). That is, the diameter of the collar portion 331 is equal to or less than the length of one side of the housing 310. In other words, when viewed from the axial direction of the knob 330, the outer circumferential end of the housing 310 is located outside (radially outward) than the outer circumferential end of the collar portion 331. In other words, the outer shape of the housing 310 is larger than the outer shape of the flange 331 when viewed from the axial direction of the knob 330.

If the outer circumferential end of the collar portion 331 is located outside the outer circumferential end of the housing 310, the terminal portion of the housing 310 will be hidden and cannot be seen when viewed from the axial direction of the knob 330, and the terminal portion of the housing 310 will be hidden. Although a problem arises in that adhesion (presence or absence of defects) cannot be confirmed, this example can prevent such a problem from occurring. Furthermore, if the outer circumferential edge of the collar portion 331 were to be located outside the outer circumferential edge of the housing 310, a problem would arise in which the identification code written on the board near the housing 310 would be hidden and cannot be seen. Accordingly, such problems can be prevented from occurring. Further, if the outer circumferential end of the collar portion 331 is located outside the outer circumferential end of the housing 310, a problem arises in that the heat dissipation effect of the heat generated by the volume adjustment switch 300 is reduced. This can prevent such problems from occurring.

Further, the diameter of the flange portion 331 is equal to or smaller than the diameter of the case opening 224. In other words, the diameter of the case opening 224 is greater than or equal to the diameter of the flange 331. When the diameter of the case opening 224 is made larger than the diameter of the flange portion 331 in this way, an effect is produced in that the level (number) becomes easier to see.

Although not shown, the diameter of the flange portion 331 may be greater than or equal to the diameter of the case opening 224. In this case, for example, even if only the knob 330 is removed from the housing 310, the diameter of the flange 331 of the knob 330 is larger than the diameter of the case opening 224, so the knob 330 will be caught in the case opening 224. Therefore, the knob 330 can be prevented from protruding (ejected) to the outside of the sub-board case 220 through the case opening 224. This prevents the knob 330 from being lost. Note that the diameter of the collar portion 331 and the diameter of the case opening 224 may be the same or approximately the same. Even in this case, similar effects can be achieved.

According to this example, since at least the case opening 224 is smaller than the size of the housing 310, even if the volume adjustment switch 300 is damaged and detached from the sub-board 210, the volume adjustment switch 300 will remain intact. This can prevent the liquid from being discharged from the case opening 224.

Further, the diameter of the flange portion 331 and the level diameter 313 (see FIG. 12(b)) (the diameter of the circumscribed circle of a predetermined display) are the same or approximately the same. In other words, the upper part (upper end) of the level display (for example, numbers 0 to 9) is located inside the outer periphery of the collar portion 331. In other words, the level diameter 313 is smaller than the diameter of the collar 331. For this reason, the upper part (upper end) of the level display (number) does not protrude beyond the outer periphery of the collar portion 331. By aligning the outer periphery of the flange 331 with the top of the predetermined display (numbers), the numbers, etc. do not protrude outside the flange 331, preventing misidentification of the set value, and also prevents the numbers, etc., from entering too much inside. Therefore, even when the knob 330 is pinched, numbers and the like can be easily recognized.

Further, the diameter of the case opening 224 is the same or approximately the same as the level diameter 313 (see FIG. 12(b)). In other words, when viewed from the axial direction of the knob 330, the diameter of the case opening 224 is such that the level (number) can be directly viewed without going through the sub-board case 220. Therefore, since the numbers can be directly viewed without going through the sub-board case 220, the level does not become difficult to see due to, for example, reflection of light on the sub-board case 220, and the numbers are easier to see. This can prevent incorrect adjustment. Moreover, the burden of adjustment can be reduced. Note that the diameter of the case opening 224 may be greater than or equal to the level diameter 313.

Further, in this embodiment, the sub-board case 220 is provided with a case opening 224, which is a hole through which the knob 330 is inserted. A gaming machine (for example, a pachinko gaming machine) has a main control board on its back side that performs main processing related to the game, and a sub-control board (for example, sub-board 210) that controls various devices in response to commands from the main control board. , a cover (back cover) attached to the back of the main frame so that it can be opened and closed (rotated) freely so as to cover the sub-board case 220 and the harness all at once, and stores a large number of game balls supplied from the island equipment of the game hall. Some are equipped with storage tanks, etc. Note that the main control board is covered with a cover member and sealed to prevent unauthorized acts.

In such a configuration, in addition to the case opening 224 of the sub-board case 220, the cover (back cover) covering the outside of the sub-board case 220 has a specific position corresponding to (opposed to) the volume adjustment switch 300 (knob 330). Provide an opening. Here, specific openings will be explained. The back cover is provided with a plurality of openings (for example, round holes) of the same shape at predetermined intervals, for example, in order to dissipate heat. The specific opening refers to an opening that is different from those openings (referred to as other openings), and for example, has a different shape from the other openings. The specific opening may be, for example, a long hole that is elongated in the vertical direction and has a width that does not allow a finger to be inserted, but allows a flathead screwdriver to be inserted. Note that the specific opening may have the same shape as other openings, but may have a different size (width, diameter, etc.). The specific opening can also be said to be an opening that is provided in a manner different from other openings. Further, the number of specific openings is not limited to one, and two or more may be provided side by side. The operator can rotate the knob 330 by inserting a flathead screwdriver or the like through a specific opening and inserting it into the horizontal groove 333 (see FIG. 14) of the knob 330. Thereby, the volume can be adjusted from the back side of the gaming machine without opening the back cover (without removing the back cover). Note that the sub-board case 220 may not be provided, only the back cover may be provided, and an opening (specific opening) may be provided at a position corresponding to (opposed to) the knob 330 in the back cover.

FIG. 33 is a schematic cross-sectional view taken along the line TT shown in FIG. 31(a). A connector opening K for inserting the connector CN is provided in the recess 225 of the sub-board case 220 at a position corresponding to (opposed to) the connector CN. When the sub-board case 220 is attached to the sub-board 210, the tip of the connector CN protrudes toward the rear side (upper side) than the connector opening K. However, as described above, the tip of this connector CN is designed not to protrude beyond the top surface 226a of the sub-board case 220.

Further, the gap between the outer circumferential surface of the connector CN and the inner circumferential surface of the connector opening K is formed small (narrow) from the viewpoint of fraud prevention. Note that in this embodiment, the gap is smaller than the gap between the outer peripheral surface of the knob 330 of the volume adjustment switch 300 and the inner peripheral surface of the case opening 224 in FIG. Furthermore, when the sub-board case 220 is placed over the sub-board 210, the connector CN is a component that may come into contact with the end of the connector opening K before other components. Since the strength of the connector CN is low, if the end of the connector opening K contacts and receives force (impact), there is a risk of damage such as chipping.

In consideration of such circumstances, in this embodiment, the connector opening K is provided with a taper. That is, the inner peripheral surface of the connector opening K is made into a tapered surface. Specifically, the inner peripheral surface is tapered so that the diameter of the connector opening K becomes smaller (gradually narrows) toward the top surface 226a (upper side). Thereby, even if the end of the connector opening K comes into contact with the connector CN when attaching the sub-board case 220, the connector CN can be prevented from being damaged because of the tapered surface. Moreover, by making the inner circumferential surface of the connector opening K a tapered surface, even if the wires come into contact with each other, it is possible to prevent the wires from deteriorating or breaking.

Further, FIG. 13 shows that the inner circumferential surface of the case opening 224 is a surface parallel to the axial direction of the knob 330. That is, the case opening 224 is shown without a taper. The reason why the case opening 224 is not tapered is that the gap between the outer circumferential surface of the knob 330 and the inner circumferential surface of the case opening 224 is larger than the gap between the connector CN and the opening. . However, the case opening 224 may also be tapered. That is, the inner circumferential surface of the case opening 224 may be a tapered surface (the end of the case opening 224 may be chamfered). Note that there are two ways to provide the taper to the case opening 224.

FIG. 34A shows an example in which the inner peripheral surface of the case opening 224 is tapered so that the diameter of the case opening 224 becomes smaller toward the substrate side (lower side). By providing the taper in this manner, even if the fingertips come into contact with the sub-board case 220 when the knob 330 is pinched, the tapered surface prevents the user from feeling pain.

FIG. 34(b) shows an example in which the inner circumferential surface of the case opening 224 is tapered so that the diameter of the case opening 224 becomes smaller toward the top (upper side). By providing a taper in this way, even if the tip of the knob 330 comes into contact with the sub-board case 220 when the sub-board case 220 is placed over the sub-board case 210, the tapered surface prevents the sub-board from falling. The position of the case 220 is forced, allowing smooth fitting.

In FIG. 33, a taper is provided in the opening K for the connector, which is likely to come into contact with other parts before other parts, but as shown in FIG. may be provided. Note that the opening for the volume adjustment switch 300 (the case opening 224) may not be tapered, and only the connector opening K may be tapered. Further, without providing a taper in the connector opening K, only the opening for the volume adjustment switch 300 (case opening 224) may be provided with a taper.

In addition, although the case where a taper is provided in the opening for protruding the connector CN and the volume adjustment switch 300 is shown above, the opening provided with a taper is not limited to the opening of the connector CN and the volume adjustment switch 300. That is, if there is a component that protrudes (exposes) from an opening formed in the sub-board case 220, the opening for that component can be provided with a taper. At this time, if the gap between the outer circumferential surface of the component and the inner circumferential surface of the opening is less than a predetermined gap (narrow gap), a taper may be provided.

Next, the liquid crystal unit 500 will be explained.
FIG. 16 is a perspective view of the liquid crystal unit 500 seen from the front.
This liquid crystal unit 500 is installed, for example, near the operation section where the MAX bet button 122 shown in FIG. 1 is provided, or near the operation section where the production operation device 26 shown in FIG. 5 is provided. It will be done. The following description will be made using the liquid crystal unit 500, but the present content is not limited to the liquid crystal unit 500, but can be applied to sub-board units other than the main board unit, LED board units, and power supply board units.

FIG. 17 is an exploded perspective view of the liquid crystal unit 500. The liquid crystal unit 500 includes a frame 510, a liquid crystal protective sheet 520, a liquid crystal module 530, a liquid crystal base 540, a liquid crystal control board (board) 550, a liquid crystal cover 560, and the like.

The frame 510 is a rectangular frame-shaped member, and is formed to cover the outer peripheral portion of the front side of the liquid crystal module 530. The frame 510 is made of resin, for example. The frame 510 is fixed to the liquid crystal base 540 by a fixing member so that the liquid crystal protective sheet 520 and the liquid crystal module 530 are sandwiched between the frame 510 and the liquid crystal base 540. Examples of the fixing member include screws and the like.

The liquid crystal protection sheet 520 is a rectangular plate-shaped member placed in front of the liquid crystal module 530. The liquid crystal protection sheet 520 is made of, for example, a PET material or a glass material, and is, for example, colorless and transparent.

The liquid crystal module 530 is, for example, a transmissive type, and is formed into a rectangular plate shape. The liquid crystal module 530 is formed of a liquid crystal layer, a polarizing filter, a color filter, a glass substrate, an alignment film, a transparent electrode, a backlight, and the like, and has a multilayer structure. FIG. 18 is a perspective view of the liquid crystal module 530 viewed from the back side (rear side). The liquid crystal module 530 includes an FPC (wiring means) 531 and is electrically connected to a liquid crystal control board 550 via the FPC 531. In this embodiment, FPC (Flexible Printed Circuits) 531 is used as this wiring means. The material of the FPC 531 is, for example, a PET film or a polyimide film, and an electric circuit is wired to the film. The FPC 531 extends from approximately the center of one long side of the liquid crystal module 530 toward the back side.

Returning to FIG. 17, explanation will be given. The liquid crystal base 540 is a substantially rectangular plate-shaped member, and is formed to hold the liquid crystal module 530 on its front side and to hold the liquid crystal control board 550 on its back side. The liquid crystal base 540 is made of resin, for example. Furthermore, a substantially rectangular through hole 541 is provided in the liquid crystal base 540 at a position facing the FPC 531 . The FPC 531 is guided to the back side of the liquid crystal base 540 (the side of the liquid crystal control board 550) through the through hole 541.

The liquid crystal control board 550 is a plate-shaped member on which a plurality of electronic components are mounted (arranged). FIG. 19 is a diagram (plan view) of the liquid crystal control board 550 viewed from the back side. Electronic components mounted on the liquid crystal control board 550 include resistors (R), ICs, capacitors, coils, diodes, and the like.
As shown in FIG. 17, the liquid crystal cover 560 is a substantially rectangular plate-shaped member, and is formed to cover the back side of the liquid crystal control board 550. The liquid crystal cover 560 is made of resin, for example. The liquid crystal cover 560 is fixed to the liquid crystal base 540 by a fixing member so that the liquid crystal control board 550 is sandwiched between the liquid crystal cover 560 and the liquid crystal base 540. Examples of the fixing member include screws and the like.

As shown in FIG. 19, a connector 551 is mounted on the liquid crystal control board 550. This connector 551 is electrically connected to the liquid crystal control board 550. In this embodiment, an angle type connector is used as the connector 551. This connector 551 is a female connector for FPC that can be fitted with FPC (wiring means) 531 (see FIG. 18). FIG. 20 is a side view of the liquid crystal control board 550, and the angle type refers to the surface E (fitting surface E) that fits (connects) with the FPC 531 when mounted on the liquid crystal control board 550. (Aperture surface E) is perpendicular to the substrate surface. This can be said to mean that the insertion/extraction direction of the FPC 531 is parallel to the board surface.

As shown in FIG. 19, the connector 551 is arranged inside (center side) of the liquid crystal control board 550, not at the outer edge of the liquid crystal control board 550. The reason why the connector 551 is provided at the center of the liquid crystal control board 550 in this way is that, for example, the FPC 531 having a predetermined length is used. If the FPC 531 having a predetermined length is used and the connector 551 is provided at the outer peripheral end of the liquid crystal control board 550, the path of the FPC 531 will protrude outside the liquid crystal control board 550. This leads to an increase in the size of the liquid crystal unit 500, which hinders space saving (downsizing).

FIG. 21 shows a state in which the FPC 531 is fitted into the connector 551, and the FPC 531 is pulled out (extended) from the connector 551. At this time, there is a region (range) where the FPC 531 and the liquid crystal control board 550 face each other, and in that region, the FPC 531 and the liquid crystal control board 550 are in close proximity. If an electronic component such as a resistor or an IC is mounted in that region, that is, a position directly below the path of the FPC 531, the FPC 531 and the electronic component will be close to each other. In this case, problems may occur, such as failure of the FPC 531 due to heat emitted from the electronic components, or failure of electronic components that have become hot.

FIG. 22 shows a state in which the FPC 531 is removed from the connector 551. In this embodiment, mounting is prohibited in a position directly below the path of the FPC 531 on the liquid crystal control board 550, that is, in a region (range) facing the FPC 531 on the liquid crystal control board 550, where no electronic components are placed (no electronic components are mounted). It is set as area G. By providing the prohibited mounting area G in this way, even if the connector 551 is placed at a location other than the outer edge of the liquid crystal control board 550, for example near the center of the liquid crystal control board 550, the FPC 531 and the electronic Parts do not come close to each other. This can prevent problems such as failure of the FPC 531 due to heat emitted from the electronic components and failure of the electronic components due to high temperatures.
No electronic components are placed in the mounting prohibited area G, and no through holes, wiring patterns, etc. are formed therein. In other words, no electronic components are placed in the mounting prohibited area G, and no processing is performed thereon. By forming the mounting prohibited area G in this manner, there is no obstacle when inserting the FPC 531 into the connector 551, and work efficiency is improved. In addition, since no processing is performed, inspection (quality control) is easy, and the time required for manufacturing can be shortened (that is, productivity is improved). Furthermore, since no processing is performed, manufacturing costs can be reduced.

In this embodiment, a case has been described in which the FPC 531 having a predetermined length is used and the connector 551 is arranged on the center side of the liquid crystal control board 550. However, for example, when using the FPC 531 with a shorter length, the connector 551 It is possible to arrange it closer to the outer periphery of the liquid crystal control board 550. In this embodiment, arranging the connector 551 at a location other than the outer edge of the liquid crystal control board 550 means that the mating surface E (see FIG. 20) of the connector 551 is aligned with the outer peripheral side surface of the liquid crystal control board 550. This means that the mating surface E is not on the same plane, and is located inside the outer peripheral side surface (outer peripheral end) of the liquid crystal control board 550, and the prohibited mounting area G is when electronic components are placed. The size is such that at least one electronic component (for example, a chip resistor) can be placed (mounted) thereon. Note that the electronic components include ICs, resistors, capacitors, LEDs, and the like.

The liquid crystal unit 500 according to the present embodiment is provided near the operation unit and may be subject to vibration, but by providing the mounting prohibited area G, the FPC 531 may move (shake) due to vibration. Even in such a case, the FPC 531 does not come into contact with electronic components, and it is possible to prevent, for example, image distortion on the liquid crystal. Further, since the mounting prohibited area G is provided, the FPC 531 and the electronic component do not come into contact with each other, and the electronic component can be prevented from receiving force from the FPC 531 and coming off from the liquid crystal control board 550. In addition, since the mounting prohibited area G is provided and no electronic components are mounted, an operator or the like can smoothly insert the FPC 531 into the connector 551, improving work efficiency.

Note that, as shown in FIG. 23, the connector 551 may include a holding portion 552 that is rotatably supported around an axis. When the FPC 531 is inserted into the connector 551 with the holding part 552 open and the holding part 552 is closed in this state, the fitting between the FPC 531 and the connector 551 is locked.

Further, as shown in FIG. 17, a wall-shaped convex portion 561 may be provided upright on the liquid crystal cover 560 at a position facing the holding portion 552 of the connector 551. The convex portion 561 is provided to prevent the holding portion 552 of the connector 551 from opening. Note that a slight gap is provided between the holding portion 552 and the convex portion 561. By providing this convex portion 561, it is possible to reliably prevent the FPC 531 from coming off from the connector 551.

In addition, in FIG. 23, the connector 551 and the electronic component T (for example, an IC) are arranged such that the left end of the connector 551 and the right end of the electronic component T are on the same straight line or approximately on the same straight line. There is. At this time, a small gap is provided between the right end of the electronic component T and the left end of the FPC 531. Therefore, when the FPC 531 is inserted into the connector 551, the electronic component T does not get in the way, improving work efficiency.

In this embodiment, a case is shown in which the FPC 531 is used as an example of wiring means. FPC is a flexible printed circuit board, and a plurality of electric circuits (wirings) are formed on an insulating film. Signals and power can be sent through the plurality of wires.
FIG. 30 is a diagram of the FPC 531 viewed from the substrate surface side. A board (not shown) is located on the front side. In this embodiment, the FPC 531 has a copper foil layer (circuit) adhered to one side of a base film (polyimide), and a cover film (polyimide) is bonded to cover the circuit in the part other than the connection part 531a (that is, the cable part 531b). ) are glued (crimped). The connecting portion 531a is a portion that is connected (inserted) to the connector 551 (see FIG. 23), and has exposed terminals (circuits). Note that the terminal may be subjected to surface treatment (for example, nickel plating). Further, the portion other than the connecting portion 531a is a cable portion 531b, and this cable portion 531b faces the board. Further, the area of the board facing the cable portion 531b is a mounting prohibited area G (see FIG. 22). Note that when the wiring means is the FPC 531, an electronic component such as a resistor may be mounted on the board-side surface of the cable portion 531b in a region that does not face the board (for example, region J in FIG. 30). Further, in this embodiment, the FPC 531 is a single layer (one side) FPC, but it may be a double-sided FPC or a multilayer FPC.
Furthermore, FFC (Flexible Flat Cable) may be used as the wiring means. The FFC is formed by sandwiching a plurality of wires (conductors) between insulating films (for example, polyimide films) from above and below with an adhesive interposed therebetween. In this case, a female connector for FFC may be used as the connector 551. Note that even when FFC is used, a connecting portion 531a (for example, an FFC connector) that is a portion connected to the connector 551 and a cable portion 531b that is a portion other than the connecting portion 531a are provided. This cable portion 531b faces the board.
FPC and FFC can be said to be thin sheet-like (film-like) flat cables. Since the flat cable has a predetermined width, a region facing the liquid crystal control board 550 is likely to be formed. Therefore, it is more effective to provide the mounting prohibited area G.

Further, as the wiring means, a harness (wire harness) in which two or more electric wires (wirings) (cables) are bundled may be used. In the harness, one male connector (connection part 531a) having a predetermined number of poles is provided at the tips of a plurality of electric wires (cable part 531b). In that case, a female connector that can fit into the male connector is used as the connector 551, and the male connector (connection portion 531a) is inserted into the connector 551. At this time, the cable portion 531b faces the board.
The wiring means has at least two wires, more preferably four or more wires, and still more preferably eight or more wires. If it has 8 wires, it is possible to send a 1-byte signal.

Furthermore, in this embodiment, a case where an angle type connector is used as an example of the connector 551 is shown, but a straight type connector, that is, a connector in which the direction of insertion and removal of the FPC 531 is perpendicular to the board surface, in other words, the mating surface E ( A connector in which the connector (see FIG. 20) is parallel to the board surface may also be used.
Note that if the connector 551 is a straight type connector, the amount of bending of the FPC (wiring means) 531 will be larger than in the case of an angle type connector, and the stress applied to the FPC 531 will increase, so there is a risk of wire breakage, etc. . On the other hand, with angle type connectors, such problems do not occur because the load due to bending is small. Further, when a straight type connector is used, the FPC 531 curves in a mountain shape in the direction away from the board. Therefore, the size of the liquid crystal cover 560 must be made larger so as not to interfere with the FPC 531. In other words, it hinders miniaturization (space saving). On the other hand, with an angle type connector, the FPC 531 passes through a position closer to the board, so such a problem does not occur. Furthermore, in the case of an angle type connector, the FPC 531 is closer to the board, so if electronic components are arranged on the board, the distance from the electronic components becomes smaller. Therefore, it is more effective to provide the mounting prohibited area G as in this embodiment. Further, when an angle type connector is used, as described above, a shape (convex portion 561 of liquid crystal cover 560) can be provided to prevent the holding portion 552 of the connector 551 from opening. Therefore, it is possible to prevent the FPC 531 from easily coming off from the connector 551.

Further, although not shown in the drawings, at least one through hole (via hole) can be provided in the mounting prohibited area G. By providing a through hole in the mounting prohibited area G, it is possible to obtain the effect of improving resistance to noise. Furthermore, by providing a through hole in the mounting prohibited area G, an air passage between the space on the front side (player side) of the liquid crystal control board 550 and the space on the rear side (back side) of the liquid crystal control board 550 is created. The two spaces communicate with each other, and a heat dissipation effect can be obtained. For example, electronic components can also be mounted on the front surface (the surface on the liquid crystal base 540 side) of the liquid crystal control board 550 (the surface opposite to the surface on which the connector 551 is mounted). In that case, heat will also be generated on the front side of the liquid crystal control board 550, but by providing the through hole, the heat will be diffused throughout (including the space on the rear side), and the liquid crystal control board 550 will be heated. It is possible to prevent breakdowns of electronic components due to high temperatures only in the space in front of the device.

Further, although not shown, at least one wiring pattern can be provided in the mounting prohibited area G. By providing a wiring pattern in the mounting prohibited area G in this manner, the degree of freedom in circuit design increases and design efficiency improves. Furthermore, if a wiring pattern is not provided in the mounting prohibited area G, there is a risk that the wiring pattern cannot be drawn unless the size of the board is increased, but it is possible to prevent the occurrence of such a problem of increasing the size. can.

Further, in the present embodiment, the mounting prohibited area G is provided on the liquid crystal control board 550, but is not limited thereto and may be provided on other boards. Other substrates include the sub-board 210, an LED board, a liquid crystal board, a power supply board, and a relay board that relays from the sub-board 210 to the LED board.

Next, the configuration of the end portion of the sub-board unit 200 will be described.
24(a) is a schematic diagram (plan view) of the sub-board unit 200 seen from the back side, and FIG. 24(b) is a schematic sectional view taken along the line VV shown in FIG. 24(a). be. FIG. 24(c) is a schematic diagram (plan view) of the sub-board 210 viewed from the back side. Although not shown, electronic components and the like are mounted on the sub-board 210. Examples of electronic components include resistors, ICs, capacitors, coils, diodes, and the like.
The sub-board case 220 (hereinafter referred to as case 220) is made of, for example, transparent resin, and has a substantially concave cross section in the vertical direction. Further, as shown in FIG. 24(c), a connector 211 is mounted on the sub-board 210. The connector 211 is an angle type female connector, and is electrically connected to the sub-board 210.
Hereinafter, one predetermined side among the four sides on the outer periphery of the sub-board 210 will be referred to as an end (outer peripheral end) α. Further, the opening (opening surface) of the connector 211 (the surface into which the male connector is inserted) is defined as an opening β. In this example, the opening β of the connector 211 faces the end α side of the sub-board 210, and the opening β and the end α are parallel to each other. Further, a predetermined distance is ensured between the opening β and the end α. The predetermined distance is, for example, approximately 2 to 3 mm. Further, one side of the case 220 located on the same side as the end α of the sub-board 210 (the side corresponding to the end α) is defined as an end (outer peripheral end) γ.

FIG. 25 is a diagram showing a configuration example of the end α of the sub-board 210, the opening β of the connector 211, and the end γ of the case 220. In FIG. 25A, the opening β of the connector 211 and the end γ of the case 220 overlap and match in plan view. In other words, the end γ of the case 220 is located directly above the opening β of the connector 211. In this state, it can be said that the connector 211 is located inside the end γ of the case 220. In other words, the case 220 exists above the connector 211.

In FIG. 25(a), the case 220 has a straight end γ, but as shown in FIG. 25(b), there is a U-shaped A notch may be formed, and the inside (inner peripheral end) (inner peripheral surface) of the notch may constitute the end γ. Hereinafter, when the case 220 is provided with a U-shaped cutout, the inner end of the cutout and the end parallel to the end α and the opening β will be referred to as the end γ. Even in the case shown in FIG. 25(b), the opening β and the end γ overlap and match in plan view.

FIG. 25(c) shows a state in which the connector (male connector) 250 of the harness is fitted into the connector 211 in the state shown in FIG. 25(b). The connector 250 is located outside the end γ of the case 220. In other words, case 220 is not present over connector 250.

According to this positional relationship of the ends, the connector 211 is located inside the end γ of the case 220, and the case 220 is located above the connector 211, so that the operator etc. Connector 211 cannot be touched from outside. This can prevent damage to the connector 211 due to force (load) being applied to the connector 211 and prevent the connector 211 from coming off from the sub-board 210.
Further, since the connector (male connector) 250 is located outside the end γ of the case 220, an operator or the like can touch the connector 250 from above in plan view. Therefore, the connector 250 can be easily disengaged from the connector 211 by pushing the claw portion (not shown), improving work efficiency. Further, as shown in FIG. 25(c), if the end (end face) on the wiring (cable) side of the connector 250 is an end δ, the end δ protrudes outward from the end α of the sub-board 210. There is. Therefore, the operator or the like can more easily hold the connector 250, making it easier to insert and remove the connector 250.

Next, another configuration example of the end α of the sub-board 210, the opening β of the connector 211, and the end γ of the case 220 will be described with reference to FIG.
In this example, in plan view, the end α of the sub-board 210, the opening β of the connector 211, and the end γ of the case 220 all overlap and match. In other words, the end α of the sub-board 210, the opening β of the connector 211, and the end γ of the case 220 are located on the same straight line.

According to this positional relationship of the ends, the connector 211 is located inside the end γ of the case 220, and the case 220 is located above the connector 211, so that the operator etc. Connector 211 cannot be touched from outside. This can prevent damage to the connector 211 due to force (load) being applied to the connector 211 and prevent the connector 211 from coming off from the sub-board 210. In addition, in plan view, the end α of the sub-board 210 and the end γ of the case 220 match, and since the sub-board 210 is covered by the case 220, foreign matter etc. do not adhere to the sub-board 210. can be prevented.
Further, since the connector (male connector) 250 is located outside the end γ of the case 220, an operator or the like can touch the connector 250 from the upper side in a plan view. Therefore, the connector 250 can be easily disengaged from the connector 211 by pushing the claw portion (not shown), improving work efficiency. Furthermore, since the connector 250 protrudes outward from the end α of the sub-board 210, it becomes easier for an operator or the like to grasp the connector 250, making it easier to insert and remove the connector 250.

Next, another configuration example of the end α of the sub-board 210, the opening β of the connector 211, and the end γ of the case 220 will be described with reference to FIG. In FIG. 27, the wiring side end δ of the connector 250 and the end α of the sub-board 210 overlap and match in plan view. This can be said to mean that the end δ of the connector 250 is in contact with the outer peripheral side surface of the sub-board 210.
If the end δ on the wiring side of the connector 250 protrudes outward from the end α of the sub-board 210, there is no sub-board 210 that functions as a wall, and the connector 250 may be touched by a finger, for example. 250 was susceptible to force (external force) (impact). Therefore, when the connector 250 is subjected to force, problems such as the connector 250 and the connector 211 becoming unfitted or the connector 211 coming off the sub-board 210 may occur. On the other hand, as shown in FIG. 26, when the wiring-side end δ of the connector 250 is aligned with the end α of the sub-board 210, the connector 250 protrudes outward from the end α of the sub-board 210. Because there is no contact with the connector 250, it is difficult for fingers or the like to touch it, and the connector 250 is difficult to receive force. This can prevent the above problem from occurring.

Next, another configuration example of the end α of the sub-board 210, the opening β of the connector 211, and the end γ of the case 220 will be described with reference to FIG.
As shown in FIG. 28(a), the end (end surface) of the connector 211 on the side opposite to the opening β (inside the board) is defined as an end ε. In this example, in plan view, the end γ of the case 220 is located inside the end ε (inside the substrate). That is, the connector 211 is located outside the end γ of the case 220 (outside the board), and the case 220 does not exist above the connector 211. Note that, as shown in FIG. 28(b), the end γ of the case 220 and the end ε of the connector 211 may be aligned in plan view.

According to this positional relationship of the ends, since the connector 211 is located outside the end γ of the case 220 (outside the board), an operator or the like can press the connector 250 while holding the upper part of the connector 211. can be inserted into connector 211. This can prevent the connector 211 from coming off the sub-board 210 due to the force (insertion force) when inserting the connector 250 into the connector 211. In particular, when the connector 211 is surface-mounted rather than insertion-mounted, a configuration like this example is more effective because surface-mounted connectors tend to come off from the board when subjected to force (adhesion strength is low). becomes.

24 to 28 show examples in which one connector 211 is mounted on the sub-board 210, but as shown in FIG. 29, a plurality of connectors 211 may be arranged in parallel on the sub-board 210. It's okay.
