  With reference to FIG. 8, the gaming machine frame 51 on which the gaming board 85 is mounted will be described. The gaming machine frame 51 shown in FIG. 6 is attached to the gaming machine installation structure of the gaming store, the gaming board 85 is attached to the gaming machine frame 51, the panel frame 57 and the ball tray structure 58 are closed, and the movable frame 53 is closed. The plug 122 of the power supply wiring 123 fixed and provided on the back side of the gaming machine frame 51 is connected to the output terminal of the island power source that outputs AC 24 volts of the gaming machine installed structure, and the power switch 124 shown in FIG. The power supply device 114 on the back surface of the gaming machine frame 51 is inserted by the player, the main control device 86 and the composite control device 87 and the symbol control device 94 on the back surface of the gaming board 85, and the launch / payout control device 115 on the back surface of the gaming machine frame 51. The main control device 86, the composite control device 87, and the symbol control device 94 are activated, and a ball called a pachinko ball is placed in the ball housing portion 68 and the tank 98. When the player operates the shooting operation mechanism 69 in a state where the ball cutting detector 113 does not output the ball cutting detection signal and the full tank detector 112 does not output the full tank detection signal, the shooting operation mechanism 69 69 outputs a variable resistance value corresponding to the operation amount of the player to the firing / dispensing control device 115. As a result, the firing / dispensing control device 115 drives the launching mechanism 77 with a cycle of less than 100 shots per minute and a launching output corresponding to the variable resistance value, for example, and the launching mechanism 77 removes the sphere supplied from the ball storage unit 68. Fire one by one.

  The ball launched from the launch mechanism 77 is launched into the game area via the launch passage of the game board 85. Balls launched into the game area collide with center decorations, winning parts, side lamps, windmills, game nails, ball repellents, etc., and flow down the gaming area to win the winning parts. The ball that has reached the bottom of the game area without winning the winning component is discharged from the out port to the back side of the game board. When a ball wins a winning component, the winning ball detector electrically detects the winning ball in the winning component and outputs a winning detection signal to the main controller 86 through wiring. Then, the main control device 86 outputs a prize ball payout signal based on the type of the winning detection signal to the firing payout control device 115, and the fire payout control device 115 pays out the number of balls as the winning balls based on the prize ball payout signal. The dispensing motor 102 is driven in the forward direction. As a result, a ball as a prize ball is paid out from the tank 98 of the tank 98.

  Thus, as the ball is paid out from the tank 98, the payout ball detector 106 outputs a payout detection signal to the launch payout control device 115 through the wiring, and the launch payout control device 115 pays out the payout detection signal from the tank 98. A calculation process is performed to count up as the number of balls that have been issued or to count down the number of set prize balls determined based on the prize ball payout signal. As a result of this arithmetic processing, the launch / payout control device 115 sets the counted up value based on the prize ball payout signal when the time when the tank 98 finishes paying out the number of balls according to the prize ball payout signal has elapsed. When the value matches the number of winning balls or the value counted down from the set number of winning balls determined based on the winning ball payout signal becomes “0”, the driving of the payout motor 102 in the forward rotation direction is stopped.

  Since the ball break detector 113 detects the presence of a ball in the tank 98 and is turned off, the firing / dispensing control is performed during the control in which the firing / dispensing control device 115 drives the dispensing motor 102 in the forward rotation direction. When the ball-out signal is not input to the device 115 and the prize ball payout signal is not input for a certain period of time, or when the firing payout control device 115 is driving the payout motor 102 in the forward rotation direction, the output torque is monitored. If the monitored output torque rises above the predetermined value, which is the threshold value, continues for a certain period of time, the firing / dispensing control device 115 determines that a ball clogging has occurred in the ball dispensing mechanism 101. Then, the polarity of the electric power supplied from the firing / dispensing control device 115 to the dispensing motor 102 is switched for a certain time so that the firing / dispensing control device 115 drives the dispensing motor 102 from the normal rotation direction to the reverse rotation direction. As a result, the payout motor 102 is driven in the reverse direction for a predetermined time. The fixed time for switching the polarity of the electric power so as to drive the payout motor 102 from the normal rotation direction to the reverse rotation direction is until immediately before the ball of the upper frame hinge 16 in the upper cover hinge arm 7 comes into contact with the left side of the take-in portion 99. It is time, and this time is calculated from the rule of thumb and set in the launch / payout control device 115.

  Thereafter, the firing / dispensing control device 115 switches the polarity of the electric power supplied from the firing / dispensing control device 115 to the dispensing motor 102 so as to drive the dispensing motor 102 from the reverse rotation direction to the normal rotation direction. Alternatively, when the discharge / dispensing control device 115 monitors the output torque during the driving of the dispensing motor 102 in the reverse direction, the monitored output torque has risen above a predetermined value as a threshold value for a certain period of time. The polarity of the electric power supplied from the firing / dispensing control device 115 to the dispensing motor 102 so that the firing / dispensing control device 115 drives the dispensing motor 102 from the reverse rotation direction to the normal rotation direction by determining that the ball has been taken into the retraction hole. Switch so that is restored. When the output torque is monitored in this way, the threshold value is set by replacing the firing / dispensing control device 115 with a predetermined time determined from the above rule of thumb. As a result, the payout motor 102 is driven in the forward rotation direction. This forward / reverse switching control is performed a predetermined number of times until the ball blockage generated in the ball payout mechanism 101 is resolved. If the ball clogging that has occurred in the ball payout mechanism 101 is not resolved even after a predetermined number of times, the firing payout control device 115 stops the forward / reverse switching control and also eliminates the ball clogging by a pachinko store clerk. Therefore, an abnormal signal is output to a not-shown alarm.
