Description

  The present invention relates to a pachinko gaming machine. More specifically, the set holding frame is provided with a holding tool and a fixing device, and holds one side end of the game board with the holding tool and fixes the other side end. The present invention relates to a pachinko gaming machine in which the game board can be exchangeably set on a set holding frame by being fixedly supported by a device.

  In gaming machines typified by pachinko gaming machines, various gaming machine components are intensively mounted on an inner frame that can be attached to and detached from the outer frame that forms the outer shell of the machine body. For example, a gaming board that is one of the gaming machine components is set in a state in which the gaming surface is directed to the front side with respect to the set opening of the set holding frame located on the back side of the middle frame. Here, as shown in Patent Document 1, the game board is attached to the middle frame (set holding frame) with one side surface of the game board being in contact with the middle frame. Is to be pushed (inserted) into the middle frame.

That is, in the pachinko gaming machine of Patent Document 1, a holding tool and a fixing device are provided in the set holding frame of the middle frame, and when the game board is attached to the set holding frame, one side end of the game board is held by the holding tool.

The setting for the mouth 13 is completed.

  Thus, according to the pachinko gaming machine P according to the embodiment, the game board D can always be held at an appropriate position, and therefore the third opening 138 provided in the lower part of the game board D is provided with the second opening. It is precisely aligned with the part 24. Therefore, the game ball launched from the hitting ball launching apparatus G and guided to the rail member 14 is always incident on the game board D from the third opening 138 at a constant incident angle. That is, by making the left and right mounting positions of the game board D with respect to the set holding frame 12 constant, it is possible to prevent the incident angle of the game balls from varying for each pachinko gaming machine. Further, as described above, since the first protrusion 148 is configured to be elastically deformed and contact the set holding frame 12, even if there is a slight error in the dimensions of the game board D, the first protrusion 148 is bent and the error is eliminated, and the game board D can be supported at a fixed position. In particular, when the game board D is larger than the reference dimension, it may be impossible to set the game board D on the set holding frame 12 by providing a protrusion that protrudes further outward from the side end surface of the game board D. . However, in the embodiment, by allowing the first protrusion 148 to be elastically deformed, the first protrusion 148 is bent inward (rightward) when the game board D is fitted, and a space margin is secured. Therefore, even a game board D slightly larger than the standard can be set. In addition, since the first protrusion 148 and the second protrusion 156 are provided two apart from each other in the vertical direction, the game board D can be supported at a total of four locations, and the upper side of the game board D and Corresponding portions on the lower side can be matched in the left-right direction.

  Since the restricting member 72 of the holder 70 is pivotally attached to a pivot member 74 fixed to the left wall surface 12b of the set retaining frame 12, the restricting member 72 has an L-shape. The first restricting surface 76 and the second restricting surface 78 intersecting with the second restricting surface 78 are rotated so as to face the front side which is the insertion side of the game board D, thereby supporting the game board support of the second restricting surface 78 and the set holding frame 12. A wide insertion space for the game board D can be defined between the surface 12a. As described above, since the space for inserting the game board D is widened, the game board D can be easily positioned with respect to the holder 70 when the game board D is attached. The possibility of scratches due to rubbing is reduced. Then, with the side end surface (held portion 146) of the game board D inserted from the insertion space being in contact with the first restriction surface 76, the game board D is rotated toward the set holding frame 12 side. The regulating member 72 also rotates integrally, and the game board D is restricted from rotating by contacting the game board support surface 12a of the set holding frame 12, and the support surface 12a and the second restriction surface 78 A side end portion of the game board D is sandwiched.

  In other words, the game board D is aligned with the window frame opening 11 by rotating with the held portion 146 in contact with the first restriction surface 76 of the holder 70, so that the game board D is positioned. Can be reduced. Further, since the held portion 146 of the game board D is sandwiched between the second restriction surface 78 of the restriction member 72 and the game board support surface 12a of the set holding frame 12, the second restriction surface 78 is used as the game board D. It is not necessary to have a size that makes contact with the entire surface of the left end of the holder, and the holder 70 can be reduced in size and weight can be reduced. Further, by reducing the size of the holding tool 70, the holding tool 70 is disposed at a position that does not interfere with the outer rail 134 even if the substantially circular outer rail 134 that defines the gaming area 136 is enlarged. And the game area 136 can be widened.

  When the game board D is mounted, the restriction member 72 is in a state where the second restriction surface 78 is separated from the game board support surface 12a in the set holding frame 12 by the biasing means 80. 78 and the game board support surface 12a of the set holding frame 12 can be opened with a wide insertion space for the game board D, and the first restriction surface 76 faces the front surface. The game board D can be inserted and positioned more easily, and the possibility of the game board D being damaged is further reduced.

  Further, since the end edge 78a of the second restricting surface 78 of the restricting member 72 is bent outward, that is, on the side away from the game board support surface 12a of the set holding frame 12, the insertion space is expanded. Thus, there is an advantage that the game board D can be attached more easily. Further, when the game board D is inserted into the insertion space, the edge 78a of the second restriction surface 78 is prevented from hitting the end face of the game board D and being damaged.

  Next, in the pachinko gaming machine P described in the embodiment, a specific configuration of the fixing device H for fixing the right end portion of the game board D to the set holding frame 12 of the middle frame B will be described below. .

An engagement holding member 37 is provided on the front surface of the third ornament 142c. In the concave molding portion 34, a locking seat 35 for the holding piece 43 of the holding portion 40 and an escape port 36 for the shaft support portion 44 are formed. The engagement holding member 37 is integrally formed with the third ornament 142c so as to be aligned with the opening front surface of the relief port 36, and on the front surface thereof, a guide slope 38 for the engagement protrusion 62 of the locking device 55 is formed. Further, an engaging recess 39 for positioning is formed.

  In the fixing device H configured as described above, the locking device 55 is fixedly set in advance on the corresponding holding portion 40 so as to be rotatable, and referring to FIGS. I will explain. That is, first, as shown in FIG. 10, the locking portion 58 and the operation portion 59 are directed forward, and the engaging portion 60 is positioned in the center portion direction (side away from the shaft hole mouth portion 42) of the set port 13. Then, the shaft portion 56 is inserted into the shaft hole 46 from the insertion port 47 of the shaft hole port portion 42 and pushed in as appropriate. Thereby, in the initial stage, the entire locking device 55 is fitted in a slightly inclined state with respect to the holding portion 40, and the shaft portion 56 is inclined in the insertion port 47 and the shaft hole 46 in the shaft hole port portion 42. Inserted.

  Next, when the locking tool 55 inserted obliquely is pushed in, as shown in FIG. In this state, the rotating support plate 57 is aligned with the fitting seat portion 45, and the shaft portion 56 is fitted and supported in the shaft hole 46 of the shaft hole port portion 42. Further, the operation portion 59 is engaged with the front surface of the inclined wall portion 27, and the engagement portion 60 is directed toward the center side of the set port 13.

  Then, after the main fitting set is completed, a finger is put on the operation unit 59 to rotate the locking tool 55 in the counterclockwise direction in FIG. As a result, the entire locking device 55 is reversed as shown in FIG. 11 with the shaft portion 56 aligned with the shaft hole 46 and the rotation support plate 57 aligned with the fitting seat portion 45 as the rotation fulcrum. Accordingly, in the process in which the engaging portion 60 is shifted to the front side of the inclined wall portion 27, the engaging protrusion 62 moves along the guide wall portion 49 and the guide slope 50 of the restricting portion 48, and the engaging concave portion 51 is rushed and locked. As a result, the locking device 55 is stationaryly set in a state where the rotation is stopped and the standby state is set at the unlocked position.

  In each fixing device H, when the locking device 55 is stationary, the engaging protrusions 62 of the engaging portion 60 are appropriately elastically deformed while moving on the guide slope 50. Then, when the engagement protrusion 62 is released from the engagement with the guide slope 50 and enters the engagement recess 51, the positioning is stopped as the unlocking end. The lock angle range) and the unlocking end point are determined automatically. Incidentally, all the locking tools 55 are rotated in the same direction.

(Set of locking devices)
Next, the action of the fixing device H described specifically will be described. Fixing devices H are respectively provided on the inclined wall portions 27 formed at the upper and lower even portions facing the left wall surface 12b on which the holding tool 70 is provided in the set holding frame 12, and in each of the fixing devices H, Prior to the installation of the game board D, the locking device 55 is fixedly set in the holding portion 40 as described above.

(Game board set)
As described above, the game board D is set in the set opening 13 by causing the regulating member 72 of each holder 70 to hold one side end portion with both the glass door and the upper ball tray fully opened. To do. As a result, the game board D is positioned, and the locking seat 35 of each of the engagement receiving portions 32 and the holding piece 43 of the holding portion 40 are brought into contact with each other, thereby being accommodated and held in a standing state.

  Next, the locking device 55 of each fixing device H is rotated clockwise (in FIG. 11) with the fingertip on the operation unit 59. As a result, each locking tool 55 is inverted from the unlocked position shown in FIG. 11 to the locking position shown in FIG. 12, and the engaging portion 60 of the locking tool 55 is engaged and held in the engagement receiving portion 32 of the game board D. In the process of shifting to the front side of the member 37, the engaging protrusion 62 moves on the guide slope 38 and then finally enters and engages with the engaging recess 39. When the engagement protrusion 62 engages with the engagement recess 39, the locking device 55 is prevented from rotating and held in the locking position.

  In each fixing device H, during the locking operation of the locking device 55, the engaging protrusion 62 of the engaging portion 60 is elastically deformed moderately while moving on the guide slope 38. Then, when the engagement protrusion 62 is released from the engagement with the guide slope 38 and enters the engagement recess 39, the engagement protrusion 62 is positioned and restrained as a locking end. The lock end point is automatically determined.

  When the locking devices 55 in all the fixing devices H are held in the locking position by the turning operation, the game board D is fixed and held in the set opening 13 of the set holding frame 12 in an appropriate posture. In particular, in each locking device 55, the engaging portion with respect to the engaging holding member 37 of the game board D is assumed on the premise that the holding piece 43 of the holding portion 40 and the locking seat 35 of the game board D are in contact with each other. 60 comes into abutment engagement with appropriate elastic deformation, and an appropriate tightening force is applied to the game board D. For this reason, the game board D is always held firmly by receiving this tightening force, and is fixedly held in a stable state against vibrations and shocks.
