PROBLEM TO BE SOLVED: To realize a game machine which enables the deletion of data backed up by a memory holding means. SOLUTION: A power source board 80 is provided with a circuit (not illustrated) which outputs an RAM clear signal for deleting data backed up in a RAM 216 in case of the interruption of a power source and a switch (not illustrated) for turning ON or OFF the operation of the circuit. With such an arrangement, the RAM clear signal can be transmitted to a microprocessor 210 by turning ON the switch to delete the data backed up in the RAM 216. Therefore, even when any prize ball data changed under the influence of static noises or by fraudulence, or the like, is backed up in the RAM 216, the deletion of the data backed up can eliminate any disadvantage, to parlors caused by paying out of balls based on the data backed up.
