Description

  The present invention relates to an accessory device in a pachinko machine.

  As shown in FIG. 10, the accessory device a of the conventional pachinko machine is installed on the upper back side of the decorative member u of the symbol display device q arranged in the approximate center of the game area r of the game board p. As shown in FIG. 11, the accessory device a rotates and rotates a rotating plate c having operating pieces d and e arranged at an angular interval of 180 ° by driving a motor b. The effect member m connected to the tip k of the arm i via the slide l is moved in the front of the game board p by swinging the arm i connected to the pivot i about the rotation axis h. It is provided so as to be switchable between a storage position (FIG. 10) hidden behind the decorative member u from the player side and an exposed position visible from the player side, and the detection switch s has a radius of 180 ° with respect to the rotating plate c. Control is made so that the driving of the motor b is stopped when any of the notches f and g arranged in the direction is detected, and the position of the effect member m at the time of the detection is set as the storage position, that is, the original position. Has been.

  However, since the space for providing a series of original position detection units for detecting the storage position of the effect member is limited, in the case of a pachinko machine that has only a small space on the back side of the decorative member, the above accessory device It may not be possible to have a structure in which the rotating plate c is rotated once as in the original position detection unit at a.

In addition, when the original position detector is configured to detect the movable piece that reciprocates within the predetermined rotation restriction range by the detection switch, the movable piece is rotated in which direction during the original position detection control. I don't know what to do, and I don't know how long the motor should be driven.
For this reason, when the movable piece is rotated, if the motor continues to be driven even after the movable piece collides with a regulating member that regulates the rotation range, the motor may be damaged due to a large load. is there. This can be avoided by providing a detection switch in the vicinity of the restricting member. However, this causes a complicated configuration of the detection unit and a cost problem.

  In this accessory device a, when the motor b rotates at the storage position of the effect member m in FIGS. 11 and 12B, the engagement between the operation piece d and the rear end j of the arm i is released. The production member m is instantaneously lowered to the lowered position by its own weight, and becomes the exposed position of FIG.

In the above-mentioned accessory device a, a considerable impact force is generated when the effect member m falls due to its own weight. For this reason, it may be necessary to provide a buffer function to alleviate the impact force. However, the impact action that occurs each time the exposure position is set causes damage to the arm i and the peripheral portion of the tip end k of the arm i. There is a fear.
None
