ABSTRACT:
A sheet feed apparatus feeds sheets, placed on a sheet receptacle, one by one toward a sheet processor. When the sheets on the receptacle are exhausted, the operation of the apparatus is interrupted by a signal from a signal emitter which operates to detect the termination of sheet delivery. The signal emitter is actuated upon the detection of the occurrence of a plurality of idling operations of the sheet feed apparatus.
