Abstract
A check system for checking a comparison check function of an information processing apparatus which includes first and second microprocessors includes a check part for supplying mutually different data to the first and second microprocessors when checking the comparison check function, and a comparing part for comparing data which are output from the first and second microprocessors in response to the mutually different data supplied to the first and second microprocessors. The comparing part generates an alarm when the data output from the first and second microprocessors are mutually different, so that correct operation of the comparison check function can be verified by the alarm when checking the comparison check function.
