PROBLEM TO BE SOLVED: To provide a game machine capable of suitably performing an arithmetic processing by control means.SOLUTION: A display CPU 72, by performing task processing in a V interruption processing started periodically, derives parameter information necessary for displaying images at each update timing. In the task processing, various arithmetic processing such as a background arithmetic processing, presentation arithmetic processing, and symbol arithmetic processing are performed, and during the performance of the task processing when a timing comes to start a new processing round of the V interruption processing, the performance of the task processing is interrupted to start the new processing round of the V interruption processing. And in a task processing in the new processing round of the V interruption processing, a performance of the arithmetic processing interrupted in the last processing round is restarted. |
