On the other hand, as shown by the solid line in FIG. 4, when the plate-like portion 24 of the lever member 16 moves to a position where the ball hole 11 is opened, the engagement protrusion 27 of the lever member 16 is disengaged from the guide receiving portion 29 of the regulating piece 31. The lever member 16 is moved rearward by the urging of the spring 26, and the engaging protrusion 27 engages with the engaging portion 30 of the restricting piece 31, and the lever member 16 is held in its rotating position. For this reason, even if the finger is released from the pressing part 19a, the lever member 16 is held in a state where the ball hole 11 is opened, and the pachinko ball of the dish part 10 falls downward from the ball hole 11 and moves to the ball. Can be stored in a box.
[0017]
Next, in order to close the ball punching hole 11, when the other pressing portion 19b of the operating member 15 in FIG. 4 is pressed with a finger, the operating member 15 rotates clockwise with the support shaft 17 as a fulcrum as shown in FIG. The engagement arm 20 engages with the engagement recess 28 of the lever member 16 and presses the engagement recess 28. As a result, the lever member 16 is pulled forward by the gap between the rotation support shaft 25 and the shaft through hole 22 as indicated by a chain line, and the engagement protrusion 27 is disengaged from the engagement portion 30 of the restriction piece 31. Therefore, the lever member 16 is rotated clockwise around the rotation support shaft 25 by the urging of the spring 26 to return to the original position shown by the solid line in FIG. Closed.
[0018]
In the above-described embodiment, the shaft through hole 22 of the lever member 16 is shown as an elliptical hole, but a circular hole having a diameter larger than that of the rotation support shaft 25 may be used. In the above-described embodiment, the lever member 16 is provided with the engagement protrusion 27, and the restriction piece 31 having the guide receiving portion 29 and the engagement portion 30 is provided on the upper surface of the support frame 12 corresponding to the engagement protrusion 27. However, as shown in FIG. 5, a restriction piece 31 may be provided on the lever member 16, and an engagement protrusion 27 may be provided on the upper surface of the support frame 12.
