In the figure, 1 is a front frame of the pachinko machine, 2 is a game board detachably attached to the back of the front frame 1, and 3 is a game board 2. It is a mechanism plate made of synthetic resin that is attached to the back surface so that it can be opened and closed. As shown in FIG. 2, a prize ball tank 4 is fixed to the upper rear surface of the mechanism plate 3. In addition, below the prize ball tank 4, a tank rail 5 for guiding the balls of the prize ball tank 4 in alignment is provided, and a prize ball payout device 7 is provided at a lower end of the flow through a bent gutter 6.
[0009]
Further, below the prize ball dispensing device 7, there is formed a prize ball discharge gutter 8 for guiding the prize ball to the front of the pachinko machine. Reference numeral 9 denotes a substantially L-shaped back cover made of synthetic resin to cover the prize ball discharge gutter 8 and a prize ball discharge control device (not shown) provided below the mechanism plate 3 from the back. The back cover 9 is detachably attached to the mechanism plate 3. An upper edge portion is provided with a pivot portion 10 horizontally, and an upper end edge of the pivot portion 10 contacts the surface of the bent gutter 6. An opening / closing lid 11 for pivotally covering the prize ball dispensing device 7 is pivotally supported.
[0010]
In FIG. 3, reference numeral 12 denotes a lock member made of a synthetic resin that is attached to the surface of the bent gutter 6 and that can open or close the lid 11. Therefore, a support shaft 14 is provided on the surface of the bent gutter 6 from a disk-shaped substrate portion 13 formed close to the upper end edge of the opening / closing lid 11, and a locking portion is provided at the tip of the support shaft 14. As shown in FIG. A receiving rod 16 projects from the surface of the bent gutter 6 above the support shaft 14 at an angle. On the other hand, as shown in FIG. 4, the lock member 12 is composed of an elliptical cylindrical long tube portion 12a whose surface is closed, and a knob 17 is integrally provided on the front surface thereof.
[0011]
Further, a shaft cylinder portion 12c is provided on one side of the long cylinder portion 12a as a locked portion that communicates via a constricted portion 12b slightly narrower than the diameter of the support shaft 14. The front and rear side surfaces of the shaft cylinder portion 12c are both opened, and the inner diameter thereof is set to be substantially the same as the outer diameter of the support shaft 14. Further, the rear surface of the long cylindrical portion 12a is notched so as to have a step 18 from the axial cylindrical portion 12c. This is because it is necessary to have Further, reference numeral 19 denotes a projection which protrudes from the back surface of the long cylindrical portion 12a. On the surface of the opening / closing lid 11, a notch 20 into which a projection 19 can be fitted is formed at the center of the leading edge, and a stopper piece 21 for determining a stop position of the lock member 12 is formed integrally therewith. I have.
[0012]
In order to attach the lock member 12 to the surface of the bent gutter 6, first, the long tubular portion 12a of the lock member 12 is fitted to the support shaft 14 as shown by a chain line in FIG. Slide to. In this state, the shaft tube portion 12c is fitted to the support shaft 14 as shown by the solid line in FIG. Then, the retaining piece 15 is locked to the outer peripheral edge of the shaft cylinder portion 12c, whereby the lock member 12 is attached to the support shaft 14 so as not to be detachable and to be rotatable. Then, as shown in FIG. 6, in a state where the opening / closing lid 11 is closed, the knob 17 is rotated downward, so that the lock member 12 comes into contact with the stopper piece 21 and at the same time, the projection 19 is in the recess 20. It fits and holds that state.
[0013]
On the other hand, in order to open the opening / closing lid 11, the knob 17 is pinched and the locking member 12 is rotated upward in the opposite direction, and the projection 19 is pulled out of the recess 20 to be removed from the surface of the opening / closing lid 11. Can be performed. At this time, if the lock member 12 is hung on the receiving rod 16, it does not return to the position where the cover 11 is closed, so that the opening and closing operation of the cover 11 is easily performed.
[0014]
The opening / closing lid 11a is also mounted on the back cover 9 of the mechanism plate 3 at a position corresponding to the winning ball discharge control device so that the opening / closing lid 11a can be freely opened and closed. Is installed. Since the operation is the same as that of the present embodiment, the description is omitted.
[0015]
