<p>PURPOSE: To provide a file control unit capable of executing a reset according to reset factors by returning a film control means to preset operation states for every reset factor according to factors of resetting decided by a reset decision means. CONSTITUTION: In the service adapter(SA) 18 of each system, the decision circuit 21 decides a factor of resetting. A frequency holding circuit 22 holds a frequency of resetting. A control storage(CS) 23 holds the reset factor as an indicator for every factor. An MPU 24 makes a reset indication according to the reset factor which is decided by the decision circuit 21 and held by the CS 23 and the reset frequency held by the frequency holding circuit 22. Consequently, resetting to the operation state corresponding to the factor of resetting becomes possible, and when the whole system needs to be reset, the whole system can be reset and when the system may be reset partially, it is reset only partially to eliminate unnecessary resetting, thereby efficiently performing file control.</p> |
