Abstract

PURPOSE: To improve safety by making power source closing to an attachment and power source closing to a copying apparatus mutually independent.
CONSTITUTION: The power source circuit of an original automatic feed part and the copying apparatus part mounted with this is constituted by voltage drop transformers 500, 501, rectifiers 502, 503, smoothing condensers 504, 505, constant voltage circuits VC1, VC2, switch FS, relays K1, K2 and switches SW1, SW2. As a result, AC is converted to DC by turning ON of the power switch SW1 and the voltage having been smoothed is held at a constant voltage by the constant voltage circuit VC1. When the original automatic feeder is held set to the copying machine part, the voltage VB1 is outputted through the contacts R0 of the relay K0 but when the power switch SW2 of the copying machine part is not held turned ON, the relay K2 is not held turned ON and therefore no output is emitted.
