PURPOSE:To resume a copiable state in a short time by reducing the electric power to be supplied to a heat source and a driving power source upon lapse of a constant time after the end of copying to economize electric power by half automatically and supplying fully electric power when the copying is restarted. CONSTITUTION:When the operator turns a power economization reset switch S3 to start copying from a half power economization state, the output (e) of a multi-F/F goes to an ''H'' and the output (g) of an OR gate U7 goes to an ''H''. Therefore, the 1st timer T1 is preset, the (h) goes to an ''L'', a transistor Tr1 is made non-conducting, and a relay RL1 and a half power economization lamp L1 go off to release the state of the half economization, by which full electric power is supplied. The copying is restarted in a short time by such constitution of changing the half power economization to the full power supply. |
