Abstract

PURPOSE: To remove the unfavourable affect due to the break of the power source by using a cheap auxiliary memory device and providing a effectiveness indicating means.
CONSTITUTION: In the case of breaking the commercial power source MB, the auxiliary power source SB supplies the power in order to maintain the contents of the auxiliary memory device SM. The device SM of cheapness is used. When the commercial power MB is turned on in the time of retaining allowable of the power source SB, the effective indication of the battery is given to the battery effective indicating means BSC and the contents of BUF during the effectiveness is transferred to the device SM. In the case that the battery retaining allowable time is passed and the commercial power is not supplied, the battery invalid indication is designated to the indicating means BSC, and judging this, all the memory information in the device SM is initially set. In this manner, on the way that the data of the function unit is all written, the bad effects resulting from the power source break of the main body can be prevented.
