IPC: B65H3/06
Filed: 1983-06-08
Abstract: PURPOSE:To eliminate an electric power loss, by turning on and off a main power source depending on the output signal of a sensor which detects the start of pulling of a waiting sheet into a machine. CONSTITUTION:A sensor 52, which detects the start of pulling of a waiting sheet into a machine caused by the action of the sheet feed mechanism A of the machine, is provided. A main powe source turn-on/off means is provided so that a main power switch is turned off when the start of pulling of the waiting sheet is not detected by the sensor 52 until the lapse of a prescribed time since the preceding detection and that the main power switch is turned on by the signal of the sensor when the start of pulling of the waiting sheet is detected by the sensor after the lapse of the prescribed time. A sheet feeder is thus prevented from waiting in a state of electricity supply, so that an electric power loss is eliminated.
