PROBLEM TO BE SOLVED: To receive a specific interruption factor in the task switching device by providing an interruption mask level setting part for making the task switching device inhibit an interruption factor below a specific interruption level and deciding the interruption factor by an interruption process part. SOLUTION: The task switching device 11 is actuated and the interruption level value for inhibiting an interruption factor in the task switching device 11 is set in an interruption factor setting part 31. Further, interruption level values are set by interruption factors in an interruption control register part 45 of a microcomputer 41. Then the interruption level values of the interruption control register part 45 are compared with the interruption level value of the interruption mask level part 44 and only interruption factors below the interruption mask level are placed in an interruption inhibited state. If an interruption factor is generated at this time, the processing is shifted to the interruption process part and the interruption factor decision part decides the interruption factor.
