IPC: G11B15/68
Filed: 1993-02-26
Abstract: PURPOSE:To certainly detect the fault of power source by discrimating whether power source is supplied again after power source is cut normally and whether a device is built up after the device is reset because of faults of power source such as an over-current, etc. CONSTITUTION:When power souce of an accesser power source part 6 is cut, the state of power source is detected and informed to a MPU 12 by an interruption in a power source monitering part 19. The MPU 12 sets a data indicating that power source is cut to a power source monitering flag A of a non-volatile memory 18 by knowing the disconnection of power source with the interruption. After the connection of power source, the MPU 12 performes an initial state diagnosis after checking the flag of the memory 18. Thereafter, when the data indicating that power source is cut is set in the flag A, the MPU judges as a normal and sets a data indicating that power source is supplied in the flag A. Furthermore, when a data indicating the connection of power source is set in the flag A, the MPU 12 outputs an erronous information by judging as an abnormal state. Thus, the expansion of the fault is prevented.
