GAME MACHINE

PROBLEM TO BE SOLVED: To control a game machine not to output announcement sound so that the work is not interrupted when an opening/closing frame of the game machine is opened out of the business hours.SOLUTION: The game machine includes: the opening/closing frame openably/closably supported to a base frame body; a detecting means capable of detecting the opening/closing state of the opening/closing frame; and an opening announcing means capable of executing the announcement with sound if the opening of the opening/closing frame is detected by the detecting means. The game machine also includes: a clocking means for clocking the time with the power from a backup power supply at the time of power failure; a time information-storing means for storing time information including the sound announcement execution period, a period in which the announcement with sound is executed; and a time determining means for determining whether the time value acquired by the clocking means is included in the sound announcement execution period or not. The opening announcing means executes announcement with sound if the opening of the opening/closing frame is detected within the sound announcement execution period, but does not execute the announcement with sound if the opening of the opening/closing frame is detected out of the sound announcement execution period.
