DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relay board mounting apparatus for a ball game machine such as a pachinko machine, an arrangement ball machine and the like.

[0002]

2. Description of the Related Art In a ball-and-ball game machine such as a pachinko machine and an arrangement ball machine, a collective plate having a ball guide passage is mounted on the rear surface of a game board, and a control board for controlling a game operation is formed by a collective plate. It is provided at the back of the game board with an interval between,
A relay board is arranged between the assembly board and the control board, and a structure is adopted in which a winning device on the game board side and electric components incorporated in other various game components are connected to the control board via the relay board.

Conventionally, as a method of mounting the relay board to the game board, conventionally, a plurality of spacers of a predetermined size are interposed between the game board and the relay board, and a long screw penetrating the spacer is used to interpose the spacer. A structure in which the relay board is fixed to the game board, and a plurality of mounting bases are fixed in advance on the back side of the game board with screws or the like, and the relay board is detachably attached by a locking portion at the tip of each mounting base. There is a structure to lock and fix.

[0004]

The conventional mounting method of the relay board has the following disadvantages. That is, the fixing structure using the spacer requires long screws, and also has the drawback that the attachment and detachment of the relay board is very difficult, and the number of man-hours required for assembling is significantly increased. In particular, after assembling each game part, if there is an abnormality in some game parts and it becomes necessary to replace them, it may be necessary to remove all of the relay board and spacer, which makes the work extremely troublesome. There are disadvantages.

In the fixing structure using the mounting base, the relay board is detachably locked to the locking portion of the mounting base. Therefore, the relay board itself can be easily attached and detached. The work of fixing to the board is indispensable.
For this reason, when the attachment of the assembly plate and other components is considered, the number of work steps is still large, and it is difficult to significantly improve the work efficiency. An object of the present invention is to provide a relay board mounting apparatus for a ball game machine which can easily and reliably mount a relay board, can significantly reduce the number of parts, and can be manufactured at low cost. I do.

[0006]

According to the present invention, a collecting board 20 having ball guide passages 67 to 69 is mounted on a rear surface of a game board 5 and a control board 23 for controlling a game operation is provided behind the game board 5. The relay board 21 is disposed on the rear side of the collecting board 20 at an interval between the collecting board 20 and the electric components on the game board 5 side to the control board 23 via the relay board 21. In the connected ball and ball game machine, the collecting plate 20 is mounted on the rear surface of the game board 5 by abutting the surface of the collecting plate 20 in a face contact manner, and the ball guide passages 67 to 69 are formed integrally with the collecting plate 20 by protruding rearward. , A plurality of locking projections 78 protruding rearward from the collecting plate 20 and arranged vertically and horizontally.

Then, since the locking projections 78 to 81 and the support pins 86 to 90 are integrally formed on the collecting plate 20, the locking projections 78 to 81 and the supporting pins are simultaneously formed when the collecting plate 20 is mounted. 86 ~
90 can be attached to the game board 5. Therefore, as compared with the case where the locking projections 78 to 81 and the like are attached separately from the collecting plate 20, the number of work steps is reduced correspondingly and the assembling work can be simplified, so that the work can be performed easily and efficiently. it can.

Further, since the locking projections 78 to 81 and the support pins 86 to 90 are integrated with the collecting plate 20, the number of parts can be greatly reduced as compared with the case where these are separately provided, and the manufacturing cost can be reduced. Can be.

When the mounting of the collecting plate 20 is completed, each lead wire
39 to 41 and the like are appropriately pulled out and placed in an easy-to-operate portion, and then the relay board 21 is engaged with the locking portions 82 to 85 of the locking projections 78 to 81 and locked. In this case, the lower end corner of the relay board 21 is inserted into and engaged with the pair of left and right locking portions 84 and 85 from above, and then the upper side of the relay board 21 is locked with the lower end as a fulcrum.
When the relay board 21 is rotated or pushed to the side, the upper edge of the relay board 21 engages with the claw-shaped locking portions 82, 83, so that the relay board 21
Can be fixed immovably up and down and left and right.

Next, while matching the colors of the male connector such as the lead wires 39 to 41 and the female connector on the relay board 21 side,
The connectors 42 to 44 and the like are sequentially connected. At this time, it is only necessary to match the colors of the connectors 42 to 44 etc.
Since there are no connection errors such as 42-44 and the connectors 42-44 etc. are arranged close to the target game parts, the complexity of the lead wires 39-41 etc. is eliminated and at the same time the lead wires 39-41
Can be prevented.

When connecting the connectors 42 to 44 and the like, an external force is applied to the relay board 21 toward the collecting plate 20. Support pins 86 to 90 are provided between the locking projections 78 to 81, respectively. This support pin 86
Since the relay board 21 is received from the assembly plate 20 side at ~ 90, the relay board 21 does not break or come off the locking portions 82-85 of the locking projections 78-81, and the connectors 42-44 etc. Can be easily and reliably connected.

Further, each of the connectors 42 to 44 is connected to the relay board 21.
The supporting pins 86 to 90 are also arranged to receive the peripheral side of the relay board 21 correspondingly, so that the force from the relay board 21 is applied to the axial center of the supporting pins 86 to 90. Take in the direction. Therefore, even if the support pins 86 to 90 are made thin, the relay board 21 can be reliably supported, and the support pins 86 to 90 can be prevented from falling down.

The support pins 86 to 90 are provided integrally with the collecting plate 20 together with the locking projections 78 to 81 having the locking portions 82 to 85, and are provided at the stage of manufacturing a mold for forming the collecting plate 20. ,Relay board
Since the relative positions of the support pins 86 to 90 with respect to 21 are reliably determined, the support pins 86 to 90 can reliably correspond to the periphery of the relay board 21. Moreover, many support pins 86
Are located at the tops of the ball guide passages 67 to 69, and the length of the support pins 86 to 89 is shortened by the height of the ball guide passages 67 to 69. Pins 86 to 90 can be made thinner.
