By the way, in a gaming machine provided with a movable member that moves by belt driving, it is usual to apply tension (tension) to the belt to such an extent that the belt does not bend during driving, but such tension is applied to the belt. Then, a load is applied to the drive motor that drives the belt. That is, since the belt tension acts on the drive shaft of the drive motor, a load is applied to the drive motor.
On the other hand, the movable member is attached to a predetermined position of the belt, but a sensor for detecting the position of the movable member is disposed close to the belt in order to improve detection accuracy.
Accordingly, in order to reduce the load applied to the drive motor, when the tension applied to the belt is reduced, that is, when the belt is loosened, the belt is started at least when the belt starts driving, during belt driving, or when belt driving stops. Therefore, the belt may come into contact with the sensor and the sensor may be damaged or the belt may be worn. For this reason, the inventor of the present invention is based on an unprecedented viewpoint of applying tension to the belt so as to be able to bend at least one of belt driving start, belt driving, and belt driving stop. It led to the invention.

An opening 155b is formed in the front wall portion of the recess 155a, a belt deviation preventing member 143B protrudes from the opening 155b toward the groove portion 156, and the tip portion thereof forms the engagement portion 147 of the groove portion 156. It is inserted into the recess 156a provided on the inner wall surface. Accordingly, a part of the opening below the groove portion 156 is blocked by the belt departure preventing member 143B. That is, the opening of the groove portion 156 is closed by the belt deviation preventing member 143B at a substantially central portion in the longitudinal direction of the groove portion 156. Therefore, even if the belt 117c bends downward at least at one of the start of belt driving, at the time of belt driving, and at the time of belt driving stop, and the belt 117c tries to come off from the groove 156, the belt 117c hits the belt deviation preventing member 143B. Thus, deviation from the groove 156 of the belt 117c is prevented.
Further, the lower surface of the groove 156 is constituted by the lower surface of a rectangular plate-shaped sensor detection unit 151 formed integrally with the opening edge of the groove 156. The sensor detection unit 151 can enter the detection range of the sensor 125.

According to the present embodiment, the belts 114c and 117c are disengaged from the belt attaching parts 140 and 141 at least one of the belt attaching part 140 and 141 at the time of belt driving start, belt driving and belt driving stop. Since the belt departure preventing members 143A and 143B are provided to prevent the belt from moving, the tension applied to the belts 114c and 117c bends at least at one of the belt driving start time, the belt driving time, and the belt driving stop time. Even if it is possible, the belts 114c and 117c can be prevented from being detached from the belt mounting portions 140 and 141 of the movable member 101 at least one of when the belt is started, when the belt is driven, and when the belt is stopped. .
Therefore, the movable members 101 and 101 can be smoothly moved while reducing the load applied to the drive motors 120 and 121 to, for example, less than 1N (Newton).

The groove portions 146 and 156 are provided with engaging portions 147 and 157 that engage with the belts 114c and 117c. Since the prevention members 143A and 143B are provided so as to close at least a part of the openings of the grooves 146 and 156, the belt is at least one of the belt driving start, the belt driving, and the belt driving stop. When 114c, 117c bends toward the opening side of the grooves 146, 156, the bent portions abut against the belt deviation preventing members 143A, 143B, so that deviation from the grooves 146, 156 of the belts 114c, 117c is ensured. Can be prevented.
Furthermore, since the tension applied to the belts 114c and 117c is smaller than the conventional one, the burden on the drive motors 120 and 121 can be reduced accordingly. Therefore, the movable members 101 and 101 that are moved by the drive motors 120 and 121 via the belts 114c and 117c can be increased in size and weight to the extent that the torque of the drive motors 120 and 121 does not become insufficient.

Even when the belts 114c and 117c are bent at least at any time when the belt drive is stopped, the belts 114c and 117c can be prevented from contacting the sensor 125 by contacting the contact preventing member 170. Therefore, damage to the sensor 125 and wear of the belts 114c and 117c caused by the belts 114c and 117c coming into contact with the sensor 125 can be prevented.
Further, the contact preventing member 170 is formed in a columnar shape, and the surface facing the belts 114c and 117c is a curved surface. Therefore, at least one of the belt driving start, the belt driving, and the belt driving stop is at least one of them. When the belts 114c and 117c come into contact with the contact preventing member 170, they come into contact with the curved surface. For this reason, wear of the belts 114c and 117c can be suppressed.
Furthermore, the belts 114c and 117c are configured such that the belts 114c and 117c cannot enter the detection range (recess 125e) of the sensor 125 at least at the time of belt driving start, belt driving, and belt driving stop. Since the belt belts 114c and 117c are provided at the positions and do not enter the detection range of the sensor 125, erroneous detection of the sensor 125 due to the belts 114c and 117c entering the detection range of the sensor 125 can be prevented.
