<p>PURPOSE:To prevent concentration of giving of game values by providing detection means for a passing ball which has passed a passing region, a variable display device, a stop command signal generating means, a display drive control means, identification information judging means and game value giving means. CONSTITUTION:When a driven ball enters a prize winning device 2, a detection switch 22 detects the ball, a flip-flop 33b is set, a data selector 33d selects a count value of a counter 33c to be given to a decoder 33e, and numerals 0-9 are sequentially periodically displayed on a segment display device 21. A set output Q is given to a monostable multivibrator 34d, the output is reversed with a delay of fixed time T1 according to a signal input when the count value of a counter 34b is detected, and during the signal output period, the counting operation of the counter 34b is prohibited. When a counting operation prohibit signal of the monostable multivibrator 34d is out, the counter 34b advances the count value again on every input pulse. The advance is made when the next pulse input is given. Accordingly, it is possible to prevent concentration of giving of game values.</p> |
