PROBLEM TO BE SOLVED: To diversely achieve continuous opening and closing operation of an opening/closing member while restraining an increase in temperature of a solenoid.SOLUTION: A game machine includes: an opening/closing member (for example, an electric tulip) capable of opening and closing a winning hole; an opening/closing drive mechanism for driving the opening/closing of the opening/closing member by a solenoid 307; and a drive circuit 1000 for driving the energization of the solenoid 307. The opening/closing member is closed during a non-excitation state of the solenoid 307 and is opened during operation after the solenoid 307 is excited and is operated. When the opening/closing member in a closed state is to be opened for a fixed period, the drive circuit 1000 energizes the solenoid 307 by a first excitation current capable of changing the opening/closing member to an open state to shift the opening/closing member to an open state, and then energizes the solenoid 307 by a second excitation current lower than the first excitation current to retain an open state.SELECTED DRAWING: Figure 10 |
