  The CPU 301 stores necessary data in the RAM 303 based on the control program stored in the ROM 302, the command data from the main control board 91 of the pachinko machine 1, and the detection result of the rotational position detection sensor 103, the motor drive circuit 304, The solenoid drive circuit 305 is controlled.

  The motor drive circuit 304 supplies a pulse signal to the stepping motor 121 based on the control from the CPU 301, and rotates the rotation axis of the stepping motor 121 by a predetermined angle.

  The solenoid drive circuit 305 causes a drive current to flow through the coil of the solenoid 144 based on the control from the CPU 301 and moves the plunger 203 (see FIG. 8) of the solenoid 144 upward. In the state where the drive current is not supplied from the solenoid drive circuit 305, the solenoid 144 moves the plunger 203 downward by the repulsive force of the built-in spring.

  The CPU 301 moves the plunger 203 of the solenoid 144 upward during a period from the start of rotation of the stepping motor 121 to a predetermined period before the rotation stop, and moves the stopper 141 (see FIG. 8) to the display plates 132a, 132b, 132c. Retreat to the outside of the rotational trajectory of 132t (see FIG. 8).

  The display control board 96 performs the same control as the leaf type display device 100a for the leaf type display devices 100b and 100c.

  With such a configuration, the leaf type display device 100a rotatably supports the plurality of display plates 132a, 132b, 132c,... 132t on the outer periphery of the cylindrical rotary drum 131 rotated by the rotation driving means, and the display surface is supported. The upper display plate of the pair of upper and lower display plates 132a, 132b, 132c,... 132t constituting the display position is stopped by stopping the rotating drum 131 at an arbitrary position while the upper display plate is locked to the display position by the stopper 141. A picture is displayed on a pair of upper and lower display boards located at the position.

  The solenoid 144 and the display control board 96 retract the stopper 141 outside the rotation locus of the display plates 132a, 132b, 132c,... 132t during a period from the start of rotation of the rotary drum 131 to a predetermined period before the rotation stop. It is a stopper retract drive control means.

  In the period from the start of rotation of the rotary drum 131 to a predetermined period before the rotation stop, the solenoid 144 holds the stopper 141 at the locking position of the display plates 132a, 132b, 132c... 132t and the display plates 132a, 132b, 132c. ... an actuator that moves between the position retracted to the outside of the 132t rotation locus.

  The display control board 96 controls the actuator and controls the stopper 141 outside the rotation locus of the display plates 132a, 132b, 132c,... 132t during a period from the start of rotation of the rotary drum 131 to a predetermined period before the rotation stop. The stopper 141 is moved to the locking position of the display plates 132a, 132b, 132c... 132t by controlling the actuator during a period from a predetermined period before the rotation of the rotary drum 131 is stopped until the start of rotation. It is a control circuit.

  The stepping motor 121 of the rotary drive unit 102 is a rotary motor that is displaced from the rotary shaft 133 of the rotary drum 131 and is arranged outside the rotary drum 131.

  The pinion gear 122 and the spur gear 123 are a gear mechanism that transmits the rotational force of the rotary motor to the rotary drum 131.

  Operation of the following leaf type display devices 100a, 100b, and 100c will be described.

  First, when the machine is set or the power is turned on, the display control board 96 controls the solenoid 144 to retract the stopper 141 to the outside of the rotation locus of the display plates 132a, 132b, 132c... 132t as shown in FIG. Next, the display control board 96 causes the stepping motor 121 to perform test rotation and rotates the spur gear 123 and the rotating drum 131 to cause the rotation position detection sensor 103 to detect the rotation position detection index 210 of the spur gear 123, thereby rotating the rotation drum. The rotation reference position 131 is detected. Thereafter, the display control board 96 uses the rotation reference position as a reference, grasps the rotation position of the rotary drum 131 based on how many pulses are supplied to the stepping motor 121 from this position, and controls the rotation of the stepping motor 121. Do.

  Thereafter, the display control board 96 moves the stopper 141 to the locking position of the display plates 132a, 132b, 132c. Next, the CPU 301 determines that the intermediate portion of the support hole 194 where the stop position of the rotating drum 131 is adjacent is positioned corresponding to the vertical center of the display window 113, that is, the display plates 132 a, 132 b, 132 c. The drive stop control of the stepping motor 121 is performed so that the pair of upper and lower display plates at the display position (in the case of FIG. 5, the display plates 132b and 132a) face the display window 113.

  When the rotary drum 131 is stopped, the upper display board (in the case of FIG. 5, the display board 132b) is locked by the stopper 141, and a pair of upper and lower display boards (in the case of FIG. 5). , The display boards 132b and 132a are vertically and planarly arranged, and a pair of upper and lower display boards (in the case of FIG. 5, the display boards 132b and 132a) is set as one set 211 (FIG. 4) from the front through the display window 113. And FIG. 5) are displayed.

The leaf type display devices 100a, 100b, and 100c start to operate upon input to the substrate 96.

  In all leaf type displays 100a, 100b, 100c, the display control board 96 retracts the stopper 141 to the outside of the rotation trajectory of the display boards 132a, 132b, 132c,... 132t, and drives the stepping motor 121. The spur gear 123 and the rotating drum 131 are rotated. Due to the rotation of the rotating drum 131, the display board (in the case of FIG. 8, the display board 132b) positioned above the display position rotates and drops downward in the forward direction. While the rotating drum 131 rotates by a predetermined angle, the stopper 141 is retracted outside the rotation locus of the display plates 132a, 132b, 132c,... 132t as shown in FIG. Rotate and fall downward in the forward direction. Such operations of the display plates 132a, 132b, 132c,... 132t are continuously performed while the rotary drum 131 is rotating.

  Thereafter, the display control board 96 moves the stopper 141 to the locking position (see FIG. 6) of the display plates 132a, 132b, 132c... 132t before a predetermined period of time when the rotation of the rotary drum 131 is stopped. Next, the CPU 301 performs drive stop control of the stepping motor 121 so that a pair of subsequent upper and lower display panels intended for display face the display window 113. In this state, the upper display panel is locked to the stopper 141, and the subsequent upper and lower display panels are displayed on the display window 113.

  According to the leaf type display devices 100a, 100b, 100c having such a configuration, in a period from the start of rotation of the rotary drum 131 that changes the display by the display plates 132a, 132b, 132c,. Since the stopper is retracted to the outside of the rotation trajectory of the display plates 132a, 132b, 132c,... 132t, the display plates 132a, 132b, 132c,. The friction between the stoppers 141 can be reduced, the wear deterioration of the display plates 132a, 132b, 132c,. , 132b, 132c ... 132t And Nikuku, it is possible to prevent the give the impression that pachinko machine 1 has deteriorated as a game machine to the player at a relatively early stage. Further, by disposing the stepping motor 121 as the rotation motor outside the rotation drum 131, the heat removal property of the stepping motor 121 is enhanced, the rotation drum 131 is made compact, and the leaf type display devices 100a, 100b, 100c are disposed.
