Reference numeral 132 is semi-transparent, and cylindrical portions 140 are provided at various locations on the board 22 into which slump bolts (not shown) are screwed for transmitting the weight of the prize ball tank 101 to the rear surface of the game board 23. A roller 141 is supported at the lower end to press against the outer periphery of the operating wheel 27 to prevent vibration of the operating wheel 27 caused by the ball firing motor.

In this pachinko machine, when the rear surface of the board 22 is tightened by the holding lever 76,
The game board 23 and its base plate 22 are pressed toward the bottom surface 51b of the fitting stepped portion 51a of the base frame 21, and the game board 23 is brought into close contact with the connecting bottom surface 51b. Therefore, the game board 23 is held and fixed at a predetermined use position without wobbling.
Furthermore, when the board 22 is closed, the flight surface of the pachinko ball that rolls out from the launch rail 60 provided on the lower plate 52 of the base frame 21 onto the game board surface is aligned with the base frame 2.
Since the lower plate 52 of 1 and the game board 23 are made to be on the same plane, an accurate flight path can be set for the shot ball.

In addition, the fixed lever 7 tends to shift its state toward the side of the game board 23 that is opened/closed/detached and replaced, and is prone to malfunctions and malfunctions.
4 is mounted on the shaft, so it can be easily repaired or replaced in the event of a malfunction.

Furthermore, even when the front frame 12 and the base frame 21 are integrally joined together, the game board 23 can be attached/detached and replaced.

In addition, in order to open and rotate the game board 23 rearward from the above-mentioned use position, the holding lever 76 is rotated to the position indicated by the two-dot chain line in FIG. Can be opened. In this way, the means for holding the game board 23 in the open position is simply provided with the holding lever 76, so the structure is extremely simple.

Effects of the Invention According to this invention, after the hook protrusion provided on the game board is engaged with the hook hole of the board, the game board main body is stored in the bottom fitting step part of the board, and the fixing lever of the game board is tightened. By simply rotating the lower plate of the base frame, the base frame, game board, and board can be easily fixed and assembled together with only two operations, which greatly simplifies the manufacturing process for installing the game board. .

Furthermore, anyone can easily position the game board with respect to the board due to the relationship between the hook hole and the hook protrusion, and the mounting position does not change after the game board is attached to the board, so that it can be easily positioned during play. Since the game board does not shift during the play, there is no problem with the game.

The game board can be extremely firmly fixed to the base frame together with the board only by rotating the fixing lever, and the mounting state will not change during transportation and use. In addition, when removing the game board during troubleshooting, the game board can be removed from the base frame by simply rotating the fixed lever in the opposite direction.

Furthermore, since the fixed lever only needs to be pivotably supported relative to the game board, the structure is simple, the manufacturing process can be shortened, and manufacturing costs can be reduced.

Furthermore, when the board is closed, the flying surface of the pachinko ball that transfers from the launch rail provided on the lower plate of the base frame to the game board becomes the same plane on the lower plate of the base frame and the game board. As a result, an accurate flight path can be set for the launched ball.

In addition, since the fixed lever, which is susceptible to breakdowns and malfunctions due to changing conditions on the side of the game board that is opened, closed, and replaced, is pivoted, it can be easily repaired or replaced in the event of a malfunction.

Furthermore, even when the front frame and the base frame are integrally joined, the game board can be attached, detached, and replaced.

Furthermore, when removing the game board from the board or assembling the pachinko machine, the adjustment and assembly of the accessory with the control unit for the accessory can be done in a completely separate location, and the game can be played with the accessory already attached. When attaching the board to the board, that is, when assembling the pachinko machine, the rear part of the accessory and the attachment point of the accessory control unit are optimally placed close to each other, so that the accessory and the control circuit unit are Connections between the two, especially electrical connections such as lead wires, become extremely easy and convenient.

In addition, since the board is provided with a protrusion permitting means that only allows the protrusion of the accessory provided on the game board to the rear, even if the accessory protrudes significantly to the rear, this accessory is not connected to the board. Not only can interference be prevented, but since the parts of the back side of the game board other than the accessory objects are covered by the substrate, the parts other than the accessory objects can be protected, and the safe balls can be prevented from reaching the back side of the game board. It is also possible to reliably prevent accidents such as escape.
