[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating body stopping device for a gaming machine, and more particularly to a rotating body stopping device for a gaming machine for accurately stopping a rotating body that rotates using a motor as a drive source at a predetermined position. .

[0002]

2. Description of the Related Art As is well known, a gaming machine such as a pachinko machine is provided with various rotating bodies. For example,
2. Description of the Related Art In a winning device called an accessory, there is a rotating body used to guide a ball to a predetermined winning port. In general, this rotating body uses a motor as a drive source, exposes a detection switch such as a photo switch or a micro switch to a motor cam, and stops the motor based on a signal from the detection switch.

[0003]

Therefore, an internal factor resulting from variations in the contact resistance of the motor and the sensitivity of the detection switch, or external factors resulting from the collision of a ball against the rotating body, vibration, etc. The stop position of the rotating body may shift. In addition, it may not stop at the correct stop position due to an installation error during assembly. This deviation cannot be guided to a predetermined winning port or the like, so it must be avoided as much as possible. Further, when a so-called character is composed of a rotating body, if the character stops in the direction of another place, the appearance is bad. Moreover, when the rotating body and the motor, which is the drive source, are connected via the gear mechanism, an error occurs due to the backlash of each gear in the gear mechanism. Further, when the reduction ratio of the gear mechanism is small (in the case of high rotation), the resistance against external force is small,
The rotating body may move after stopping. The same applies when a friction transmission mechanism is used to transmit the driving force. Therefore, the present invention has been proposed in view of the above, and an object thereof is to provide a rotating body stopping device in a gaming machine capable of accurately stopping the rotating body at a predetermined position and holding the stopped position. .

[0004]

In order to achieve the above object, the present invention is a rotating body stopping device in a game machine that rotates using a motor as a drive source, wherein the rotating body has a convex or concave engagement. And a position regulation control member having an engagement receiving portion that can be fitted with the engagement portion is made to face the engagement portion, and the position regulation control member is operated when the rotating body is stopped. The stop position of the rotating body is regulated.

[0005]

By engaging the engaging portion provided on the rotating body with the engaging receiving portion provided on the position regulation control member, the stopping position of the rotating body can be regulated and the stopped state can be maintained. . Therefore, when the sphere guiding means is formed on the rotating body, the sphere can be accurately guided in a desired direction.
