PROBLEM TO BE SOLVED: To facilitate data management of prize ball discharge and lending ball discharge by memorizing the additional number of prize ball discharges separately from the number of all balls discharged from a ball discharge unit, and memorizing the number of lending balls discharged by lending ball discharge control signals. SOLUTION: When a lending operation is made by a game player with insertion of a prepaid card, a lending ball discharge control signal to discharge a predetermined number of lending balls is outputted, and the lending ball data regarding the discharged lending balls is memorized. This lending ball data is converted into an optical signal by a signal converter 109 and transmitted to a management unit 95. A ball discharge unit controller 112 is formed so as to discharge a predetermined number of balls from a ball discharge unit based on a prize ball discharge signal or a lending ball discharge control signal, the discharged number of prize balls discharged from the ball discharge unit is additionally memorized, and a prize ball dispensing signal is issued on every additional value reaching a predetermined value. |
