PROBLEM TO BE SOLVED: To reduce an influence upon real-time processing of a driver in the interrupt control method which integrates interrupts occurring in plural circuits into one to connect them to a computer. SOLUTION: A driver 8 controls plural circuits 5 to 7 through an operating system 3 and reports a work importance degree, which indicates the degree of importance of a work being executed in this time, to an interrupt report means 10 through the operating system 3, and an interrupt request storage means 9 receives first interrupt information from plural circuits as the input and generates and holds information on the presence/absence of an interrupt request and the degree of importance of the interrupt with respect to each of plural circuits; and if an interrupt request is issued from any circuit, the interrupt report means 10 compares the degree of importance of the interrupt corresponding to this request with the degree of importance of the work in the driver 8 to adjust the time when second interrupt information will be reported to the computer 1.
