APPLYING SYSTEM OF MAIN POWER SUPPLY FOR FACSIMILE

摘要

PURPOSE:To redude loss time and to reduce the cost, by applying a main power supply through a setting operation of an original in addition to the application of the main power supply. CONSTITUTION:A pulse generating circuit 15 connected to an original detection switch 14 and a waveform shaping circuit 12 connected to a main power supply switch 11 are provided to a circuit 3 which operates a constantly opened switch 5 for a main power supply 4. Thus the power supply 4 can be turned on through either one of the circuits 15 and 12 if the other circuit is faulted. Thus the original can be transmitted if it is suddenly set.
