Abstract
PURPOSE: To heighten work efficiency, by providing a plurality of photoelectric converters in prescribed positions near nip rollers which pinch a sheet, to true up the moving direction of the sheet.
CONSTITUTION: A plurality of photoelectric converters 4a0..., 4b0... are provided near a pair of nip rollers 1a, 1b which are a fixed and a movable rollers 2, 3 for pinching a sheet S, so that the photoelectric converters are placed at as small intervals as possible in the direction of the width of the sheet S over across both its side edges. Electric signals, which produced by the photoelectric converters 4a0..., 4b0... when the sheet S is present, are received by a comparison and judgment circuit 5 to judge whether the sheet has deviated rightward or leftward. A control circuit 6 or 7 is caused to generate an output to eliminate the compressive force of the right or left roller 1b or 1a to correct the deviation.
