And attachment portions 15 and 16 for attaching decorations (not shown).

A method for assembling the gaming machine drive device 1 according to the embodiment of the present invention will be described.
First, after the upper end portion of the screw shaft 6 is inserted into the sliding holes 7a and 7b of the movable body 7, the bearing 12 is fitted, and the lower end portion of the screw shaft 6 is fitted to the bearing 9e. Next, after the lower end bearing 9e is fitted into the motor base 9d, the bearing 12 is fitted into the hole of the upper end 8b of the base 8, and the motor base 9d is assembled to the base 8. Next, after fitting the connecting member 9c to the motor shaft 9a, the motor 9b is attached to the motor base 9d so that the convex portion of the connecting member 9c and the concave portion of the bearing 9e are fitted, and the driving portion 9 is assembled. Next, the photosensor 11 is mounted in the sensor mounting portion 8d, the ball 10 is placed in the inner wall hole portion 7c, and sealed with the lid 7e. The ball 10 is sealed between the recess formed by the inner wall hole 7c and the lid 7e of the movable body 7 and the spiral groove 2 of the screw shaft 6, and is bitten into the spiral groove 2 so as to be able to roll. In the completed state, it is exposed to the outside except for the part of the screw shaft 6 accommodated in the movable body 7.

  A driving method of the gaming machine driving device 1 according to the embodiment of the present invention will be described. When the motor 9 b is driven at the position shown in FIG. 2, the drive unit 9 rotates the screw shaft 6 about the axis. The ball 10 is loosely fitted in the spiral groove 2 of the screw shaft 6 and is held in a recess formed by the inner wall hole 7c of the movable body 7 and the lid 7e. While moving, it slides linearly with the movable body 7 downward in the Y direction parallel to the axial direction of the screw shaft 6. When the motor 9 b is rotated in the reverse direction, the ball 10 is held in the concave portion formed by the spiral groove 2 of the screw shaft 6, the inner wall hole 7 c of the movable body 7 and the lid 7 e, and the ball 10 follows the movement of the spiral groove 2. While the rolling contact, the position is changed upward, and the movable body 7 is linearly slid and moved upward in the Y direction parallel to the axial direction of the screw shaft 6.

  According to the gaming machine drive device 1 of the embodiment of the present invention, the groove portion non-formation regions 4 and 5 do not require processing of the spiral groove 2 of the screw shaft 6 to the end, and the bearing can be held. There is no need for additional processing and the processing time is shortened, so the cost can be reduced. Since there are no spiral grooves 2 in the groove non-formation regions 4 and 5, the handling is easy, and the operation can be performed safely when the drive device 1 is assembled.

  After the assembly of the driving device 1 is completed, the ball 10 is inserted into the inner wall hole portion 7c and the lid 7e is attached. Therefore, assembly is easy, the structure is simple, and durability is increased. Further, once the ball 10 is bitten into the spiral groove 2, it does not jump out of the movable body 7.

  If the pitch of the spiral groove 2 of the screw shaft 6 is increased, the moving speed can be increased. Further, the accuracy of the spiral groove 2 may not be high.

  The driving device 1 can drive a heavy movable object 7 in the vertical direction, and a lock mechanism is not required to hold the position of the movable object 7. The screw shaft driving unit 100 of the comparative example shown in FIG. 7 includes a guide rib 101 as a female screw. If the movable object 7 is a heavy object, the guide rib 101 may be broken or scraped. In the present invention, this inconvenience is solved.
