PURPOSE:To make it possible to extend a holding time of information of an information processor by detecting an instantaneous cutting-off of commercial power supply and supplying the holding power of power supply to a main controlling circuit holding informations only. CONSTITUTION:Power supply 1 supplies the stabilized DC power to a display device 5, a printer device 6, a floppy disk device 7 and a main controlling circuit 3. When the voltage-drop caused by an instantaneous cutting-off is detected by a voltage detection circuit 2, the main controlling circuit 3 moves an ON/OFF circuit 4 to the OFF position to stop the feed to the display device 5, printer device 6 and floppy disk device 7. According to the constitution, a load of the power supply 1 is limited to the main controlling circuit 3 only. |
