Abstract

PURPOSE:To increase available efficiency of data processing by providing a timer circuit to output a reset signal to a latching relay after elapsing a variable setting time from power failure detection. CONSTITUTION:On the occasion of using, users set a required back up time at volume 19. If commercial power supply is normal, a latching relay 6 is kept in a set condition by a set signal 10, and a contact 7 is turned on. If electrical power fails, a signal 17 of a power failure detection circuit 16 becomes active, DC from a battery 5 is converted into AC to output to an output terminal 26. Simultaneously, a timer circuit 18 wakes up, and the latching relay 6 is kept in a resetting condition by a signal 20 after elapsing previously set time. According to the constitution, the contact 7 is disconnected to stop the supply of power to a control circuit 12.
