Title: game machine
IPC: A63F7/02
Filed: 2022-07-04
Abstract: PROBLEM TO BE SOLVED: To simplify control processing of a game machine. 
     SOLUTION: When a valid period in which operation by operation means becomes valid is set, a performance is executed when the operation means is operated within a valid period in which a first period of the valid period passes. Meanwhile, when the operation means is operated before lapse of the first period of the valid period, execution of the performance is delayed. Thus, start timing of a performance to be executed based on the operation means can be limited, thus simplifying control processing as compared with a possibility of start of the performance during all periods within the valid period.
