When the player operates the firing operation mechanism 69 shown in FIG. 9 in a state where the full-charge detection signal 112 is not output, the firing operation mechanism 69 generates a variable resistance value corresponding to the operation amount of the player. Output to 1. As a result, the firing / dispensing control device 1 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 shown in FIG. Balls fired in the game area flow down the game area while changing the direction of flow by colliding with center decorations, winning parts, side lamps, windmills, game nails, ball repellents etc. provided in the game area, Win a prize part. 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 according to the type of the winning detection signal to the launch payout control device 1 so that the launch payout control device 1 pays out a number of balls as prize 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.

  As described above, 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 1 through the wiring, and the launch payout control device 1 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 apparatus 1 is set such that the counted up value is determined based on the prize ball payout signal when the time when the tank 98 has finished 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 1 drives the dispensing motor 102 in the forward rotation direction. When the ball break signal is not input to the device 1 and the prize ball payout signal is not input for a certain period of time, or when the firing payout control device 1 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 1 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 1 to the dispensing motor 102 is switched for a certain time so that the firing / dispensing control device 1 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 forward rotation direction to the reverse rotation direction is the time until immediately before the ball of the intake portion 99 in the tank 98 contacts the right side portion of the intake portion 99. Thus, this time is determined from the empirical rule and set in the firing and dispensing control device 1.

  Thereafter, the firing / dispensing control device 1 switches the polarity of the power supplied from the firing / dispensing control device 1 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 1 monitors the output torque during driving of the dispensing motor 102 in the reverse rotation direction, the state in which the monitored output torque rises above a predetermined value as a threshold value continues for a certain period of time. The polarity of the electric power supplied from the firing / dispensing control device 1 to the dispensing motor 102 so that the firing / dispensing control device 1 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, a threshold value is set by replacing the firing / dispensing control device 1 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 1 stops the forward / reverse switching control and also eliminates the ball clogging by the store clerk at the pachinko parlor. Therefore, an abnormal signal is output to a not-shown alarm.

  Any control device can be applied as long as it is attached to the back surface of the game main body storage structure 56 other than the launch / payout control device 1. Although the firing / dispensing control device 1 is installed on the left side of the game main body storage structure 56, it may be on the right side, but in this case, the operation direction for mounting the firing / dispensing control device 1 in the best mode on the mounting base 2 is reversed left and right.
