  As shown in FIG. 3, the rotating plate 23 is rotated by lower guide portions 34 </ b> A and 34 </ b> B and an upper guide portion 34 </ b> C provided to be engaged with the upper portion, the lower left portion and the lower right portion of the back plate portion 22 b of the case 22. Supported as possible. An arcuate first guided portion 23e guided by the lower guide portions 34A and 34B is formed on the outer peripheral edge of the large diameter portion 23a. An arc-shaped second guided portion 23f that is guided by the above-described upper guide portion 34C is formed on the outer edge of the small diameter portion 23b. The arc of the first guided portion 23e and the arc of the second guided portion 23f are concentric, and the arc of the second guided portion 23f is set to have a smaller diameter than the arc of the first guided portion 23e. Between the first guided portion 23e and the second guided portion 23f, there is a flat step portion 23c extending leftward from the left end of the first guided portion 23e, and a right end portion of the first guided portion 23e. A step portion 23d extending in the right direction is formed.

  The lower guide portions 34 </ b> A and 34 </ b> C and the upper guide portion 34 </ b> C are guide rollers provided so as to be rotatable around an axis substantially orthogonal to the back plate portion 22 b of the case 22. The lower guide portions 34A and 34B and the upper guide portion 34C have the same structure, and the structure is a double roller structure in which two roller members are arranged in the axial direction. This double roller structure will be described by taking the lower guide portion 34A that supports the lower left portion of the rotating plate 23 as an example.

  As shown in FIG. 8, the lower guide portion 34 </ b> A that supports the lower left portion of the rotating plate 23 includes a support shaft 35 that protrudes forward from the back plate portion 22 b of the case 22, and the support shaft 35 as a center.

  The lower guide portion 34B that guides the lower right portion of the rotating plate 23 has the same structure as the lower guide portion 34A. When the left and right lower portions of the rotating plate 23 are supported by the lower guide portions 34A and 34B of the double roller structure, the first guided portion 23e and the lower guide portions 34A and 34B It is possible to smoothly rotate the rotating plate 23 by reducing the frictional resistance generated between the two. The structure of the upper guide portion 34C that supports the upper center of the rotating plate 23 is also such that the diameter dimensions of the front roller member and the rear roller member are smaller than those of the front roller member 34a and the rear roller member 34b of the lower guide portion 34A. Thus, it has the same double roller structure as the lower guide portion 34A. However, since the weight of the rotating plate 23 does not act on the upper guide portion 34C, the double guide structure is not necessary. That is, the roller may be in contact with the collar portion in the radial direction.

  As shown in FIG. 3, a fall prevention piece 24 is integrally formed at a location of the case 22 located below the rotating plate 23. The fall prevention piece 24 is located on a perpendicular L passing through the rotation center O of the rotating plate 23. The fall prevention piece 24 and the outer peripheral edge of the rotary plate 23 are located at a predetermined interval so that the fall prevention piece 24 does not hinder the rotation operation of the rotary plate 23. However, when the lower guide portions 34A and 34B supporting the rotating plate 23 are damaged or the rotating plate 23 is detached from the lower guide portions 34A and 34B due to an external impact or the like, the outer peripheral edge of the rotating plate 23 falls. Since the further movement is restricted when it contacts the upper end of the prevention piece 24, the fall accident of the rotating plate 23 can be prevented reliably.

  A rotation drive motor 29 is attached to a portion of the case 22 located below the rotary plate 23. A ring gear 36 is provided on the lower outer peripheral edge on the surface side of the rotating plate 23. A reduction gear train 30 is interposed between the ring gear 36 and the rotary drive motor 29.

The final gear 30 b meshes with the ring gear 36 in the vicinity of the perpendicular L passing through the rotation center O of the rotating plate 23. That is, the rotation of the rotation drive motor 29 is transmitted to the rotating plate 23 via the reduction gear train 30 and the ring gear 36.

  In the case of the present embodiment, the rotating plate 23 is controlled by setting the posture of the rotating plate 23 shown in FIG. 9 as an initial posture with a rotation angle of 0 °, and 45 ° in each of the clockwise and counterclockwise directions as an upper limit angle.

  Between the case 22 and the rotating plate 23, there is provided a stopper structure that defines a limit angle of rotation of the rotating plate 23 with respect to each of clockwise rotation and counterclockwise rotation of the rotating plate 23.

It is configured. The stopper structure for counterclockwise rotation includes a stopper portion 28 that protrudes forward in the vicinity of the right side of the upper center of the back plate 22c of the case 22, and the step portion 23d described above. The stopper portions 27 and 28 are set at positions within the range from the rotation center O to the same distance as the radius of the first guided portion 23e above the rotation center O of the rotation plate 23. They are located opposite to each other with a perpendicular L passing through the rotation center O. That is, as shown in FIG. 10, the limit angle of clockwise rotation of the rotating plate 23 is an angle at which the stepped portion 23 c comes into contact with the stopper portion 27. Further, as shown in FIG. 11, the limit angle of the counterclockwise rotation operation of the rotating plate 23 is an angle at which the step portion 23 d abuts against the stopper portion 28.

  In both the stopper structures described above, the limit angle of rotation of the rotating plate 23 is set slightly larger than the upper limit angle 45 ° in terms of control. That is, the stopper portion 27 and the step portion 23c prevent the rotating plate 23 from rotating excessively beyond the upper limit angle of 45 ° in the clockwise direction, and the stopper portion 28 and the step portion 23d have the rotating plate 23 counterclockwise. In this case, excessive rotation beyond the upper limit angle of 45 ° is prevented.

  As shown in FIGS. 14 and 15, the wall portion 22 c of the case 22 is positioned close to the stopper portions 27 and 28. As can be seen with reference to FIGS. 13, 15, and 16, the stopper portion 27 includes a substantially truncated cone-shaped base portion 27a formed protruding from the back plate portion 22b, and a game board from the base portion 27a.
