ABSTRACT:
A paper feed device for the printer of an electronic calculator or the like, has a paper detector which comprises a light-emitting diode and a phototransistor having registered optical axes. If a paper sheet is not detected when a paper feed key or the like is depressed, the paper sheet feed operation continues, even after the paper feed key is released, until the paper detector detects the paper sheet. Operability of paper feed is improved. The rest position in the printer of the leading edge of the paper sheet is determined by the position of the paper detector to thereby determine a constant printing position for the paper.
