The one-way clutch 750 may be disposed inside the case member 720 of the drive motor 700. In this case, the one-way clutch 750 may be disposed between the bottom portion of the base portion 720A of the case member 720 and the rotor 740, as shown in FIG. As described above, the case member 720 may be disposed at a position between the lid 720 </ b> B and the rotor 740.

  FIGS. 13A and 13B are diagrams showing an example in which the one-way clutch 750 is attached to the case member 720 of the drive motor 700 via the bracket 770. FIG. As shown in the figure, the bracket 770 that holds the one-way clutch 750 may be fixed to the outside of the case member 720 with a screw or the like. In this way, the one-way clutch 750 can be easily attached and detached. Further, the one-way clutch 750 can be easily attached to a general motor that is not provided with a one-way clutch in advance. In this case, it goes without saying that the one-way clutch 750 may be attached to either the output end 750A side or the rear end 710B side. Further, the bracket 770 may be fixed to something other than the case member (for example, a metal frame 626 or the like).

  When the motor shaft 710 of the drive motor 700 rotates, the drive gear 618 fixed to the motor shaft 710 is rotationally driven, and the movable body gear 620 is rotationally driven by the drive gear 618. Then, this rotational driving force is transmitted to the mounting portion 612C of the first reel frame 612. As a result, the reel band 610 fixed to the first reel frame 612 is rotationally driven.

  That is, the power of the drive motor 700 is transmitted in the order of the motor shaft 710 → the drive gear 618 → the movable body gear 620 → the first reel frame 612 → the reel band 610.

  FIG. 14A is a schematic side view of the moment when the drive motor 700 is stopped and the reels 110 (111, 112) are stopped as viewed from the first reel frame 612 side, and FIG. 14B is the drive motor. It is the schematic side view which showed a mode that the reel 110 (111,112) was shaken slightly in the rotation direction after 700 was stopped.

  When stopping the drive motor 700 which is a stepping motor, the control is performed so that the stator 730 is changed from 1-2 phase excitation to 2 phase excitation and the motor shaft 710 is held in a stopped state. However, the reels 110 (111, 112) try to continue to rotate due to inertia and are slightly swung in the rotation direction as shown in FIG. 14B, and accordingly, the motor shaft 710 is also rotated in the rotation direction (forward direction). It will rotate slightly. Kinetic energy is absorbed by the rotation of the reels 110 (111, 112) and the motor shaft 710. Next, the reels 110 (111, 112) and the motor shaft 710 attempt to return to a controlled position (position where the stator 730 attracts the rotor 740) so as to be held in a stopped state, thereby causing vibration. Since the one-way clutch 750 does not allow the motor shaft 710 to rotate in the reverse direction, the reels 110 (111, 112) and the motor shaft 710 cannot rotate in the reverse direction, and the occurrence of vibration is prevented. It becomes. As described above, according to the variable display device 602, it is possible to prevent the occurrence of vibration when the rotation of the reels 110 (111, 112) is stopped.

  <Main control unit main processing>

  Next, the main process of the main control unit 300 will be described with reference to FIG. FIG. 3 is a flowchart showing the flow of main processing of the main control unit 300.

  Basic control of the game is performed mainly by the Main CPU 310 of the main control unit 300, and unless the power supply is detected, the main CPU 310 repeatedly executes the main control unit main process of FIG. Become.

  When power is turned on to the slot machine 100, first, various initialization processes are executed. Thereafter, in step S101 of the main control unit main process, a process related to medal insertion is performed. Here, it is checked whether or not medals have been inserted, and the winning line display lamp 120 is turned on according to the number of medals inserted.

  In step S102, a process related to a game start operation is performed. Here, it is checked whether or not the start lever 135 has been operated. If it is determined that the start operation has been performed, the number of inserted medals is determined.

  In step S103, a valid pay line 114 is determined.

  In step S104, the random number generated by the random number generator 317 is acquired.

  In step S105, the winning combination internal lottery is performed using the random value acquired in step S104 and the winning combination lottery table stored in the ROM 312.

  In step S106, rotation of all the reels 110 to 112 is started by a reel rotation start process. At this time, based on the internal lottery result in step S105, the stop position data selection table is referred to, and any one reel stop control table is selected.

  In step S107, the reels 110 to 112 corresponding to the pressed stop buttons 137 to 139 are stopped from rotating by the reel stop control process. At this time, the reels 110 to 112 are stopped based on the reel stop control table selected in step S106.

  In step S108, the winning determination of the symbols stopped when the stop buttons 137 to 139 are pressed is performed. Here, it is determined that the winning combination is won when the winning winning combination 114 corresponding to the internal winning winning combination or the winning combination having the flag carried over is arranged (displayed). . For example, if “Replay-Replay-Replay” is arranged on the validated winning line 114, it is determined that the player wins the replay.

  In step S109, a medal payout process is performed. In this medal payout process, if a winning combination with a payout is won, the number of medals corresponding to the winning combination is paid out.

  In step S110, a game state control process is performed. In this gaming state control process, control for shifting the gaming state is performed.

  As described above, the gaming machine motor 700 according to the embodiment of the present invention (in this embodiment, a drive motor that is a stepping motor) 700 is a movable body (in this embodiment, a reel) 110 (111, 112). A one-way clutch 750 that is a motor of a gaming table (in this embodiment, a slot machine) 100 that allows the motor shaft 710 that outputs power to be rotated only in one direction and cannot be rotated in the reverse direction. Prepare. Therefore, when the movable body 110 (111, 112) is stopped, the operation of the movable body 110 (111, 112) and the rotation of the motor shaft 710 are slightly continued to absorb kinetic energy, and the movable body 110 ( 111, 112) and the motor shaft 710 are not rotated in the reverse direction, it is possible to suppress vibration when the movable body 110 (111, 112) is stopped.

  Further, since the case member 720 that rotatably supports the motor shaft 710 is further provided and the one-way clutch 750 is disposed on the case member 720, the motor 700 has a vibration suppressing function. By simply exchanging the motor 700 without changing the movable body drive mechanism, it is possible to add a vibration suppression function to the gaming table 100, and to reduce the development cost and manufacturing cost of the gaming table 100.
