PROBLEM TO BE SOLVED: To carry out the processing of starting a controller normally at the closing of a power source or in the return of the power source back. SOLUTION: A game machine is provided with a CPU (central processing unit) and a memory for temporarily storing data. When electric power is supplied to the game machine from an external power source, the power is supplied to the CPU and a memory from a power source circuit. On the other hand, when the supply of the power to the game machine from the external power source is shut down, the power is supplied to the memory from a backup power source. At the closing of the power source or in the return of the power source to the normal condition, the CPU writes data into a prescribed address of the memory (S4) and the data is read out of the prescribed address of the memory (S6) to determine whether the data written at the step S4 coincides with the data read out at the step S6 (S8). The steps S4 and S6 are repeated until the coincidence of the data is determined at the step S8, and when the coincidence of the data is found at the step S8, a normal startup processing is started (after S10).
