When a game car wins a prize in the winning device 13, the prize ball discharging device 17 discharges a certain number of prize balls and guides them to the upper ball receiving tray 5 through the gutter 19.

As shown in FIGS. 4 to 6, the firing device 18 has a guide passage 22 formed in the guide passage 22 that guides the game cars flowing in from the ball introduction port 21 opened in the front wall of the box 20 to the firing position 9. A firing hammer 26 is provided, which is integrally formed with a protruding arm part 24 for sending the game car held by the recessed part 23 into the firing position 9, and a hammer head 25 for driving the game car at the firing position 9 into the game part 8a. configured.

The firing hammer 26 is rotatably supported approximately in the middle by a shaft 27, and a spring 29 for adjusting firing force is connected to the rotating bundle 7 via a wire 28 toward the rear end of the shaft 27. One end of the firing rod 30 is locked, and the firing rod 30 is normally biased clockwise by the spring 29 and is placed in the solid line position in FIG. 6 by coming into contact with the stopper circumference rubber 31.

Reference numeral 32 denotes a firing ball control device, in which a motor 33 is driven by the rotating operation of the rotating bundle 7, and synchronizes the firing rod 30 with each rental ball thrown into the upper ball receiving tray 5. Push it up to one side, rotate the firing hammer 26 as shown by the chain line in FIG. An operation is performed in which the game car is returned to its original position by biasing and is placed at the firing position 9, and is fired by the game section 8a.

The rented balls are ejected from the machine through the ejection passage 34 after the ejection hammer 26 is ejected, and the winning device 13
The game car that has won a prize will flow into the out ball mouth 14, and the game car that has won a prize will be discharged from the winning gutter 35. The out balls are discharged to the outside of the machine through the out ball discharge gutter 36.

Furthermore, the two channels a and l) of the gutter rail 16 are connected to the prize ball discharging device 17 via a bent gutter 37, and the channel C is connected to the firing device 1 via a bent gutter 38 and a guide gutter 39.
It is connected to the ball introduction port 21 of No. 8.

Therefore, the pachinko balls that fall from the drop opening 40 of the ball tank 15 onto the gutter rail 16 and flow down the two channels a and l) are guided as prize balls to the prize ball discharging device 17, and are guided down the channel C. Pachinko balls flowing down are guided to a firing device 18 as a game vehicle.

Further, the firing device 18 is attached to the inner surface of the table frame 2 located at the upper side of the game board 8 using appropriate fixing means such as screws, and the downstream end of the guide gutter 39 can be freely separated from the firing device 18. It is attached to a mechanism plate 41 which is attached to the back of the game board in a detachable manner.

The guide gutter 39 is formed into a substantially U-shaped cross section with one side surface open, and a cover plate 49 is attached to the open portion so as to be openable and closable, so that dirt on the bottom surface of the guide gutter 39 can be easily removed. It's a formality.

A pair of support plates 4 are provided below the guide gutter 39.
