PROBLEM TO BE SOLVED: To appropriately execute processing relating to updating of a plurality of period measuring means.SOLUTION: In an MPU 92 of a main control device 71, jackpot lottery is executed on the basis of detection of a game ball in an upper operation hole detection sensor 33a or a lower operation hole detection sensor 34c, a performance for a game round is started and the performance is continued for a predetermined period. Open lottery is executed on the basis of detection of a game ball in gate detection sensors 35a and 35b and a result is reported after the lapse of a predetermined period. In the case of an opening win, an electric accessory of a lower operation hole is brought into an open state. An RWM 94 of the main control device 71 includes a plurality of timer counters and in the MPU 92, these timer counters are utilized to measure the predetermined period. In such a case, processing for updating the plurality of timer counters is set while being consolidated separately from processing utilizing those timer counters. |
