PHOTOSENSITIVE BELT POSITION SENSING DEVICE OF PRINTER OF WETTING ELECTROPHOTOGRAPHIC METHOD

摘要

PURPOSE: A photosensitive belt position sensing device of a wetting electrophotographic method printer is provided to improve the structure for sensing the position change of a photosensitive belt generated as the photosensitive belt is running. CONSTITUTION: The photosensitive belt position sensing device comprises:a shoe unit contacted to the latent non-electrostatic image range of a photosensitive belt; a shoe slot formed by penetrating the shoe unit contacted to the edge of the photosensitive belt; a shoe block installed in a side of a frame; a roller installed between the other side of the frame and the shoe block to be arranged to the width wise of the photosensitive belt, revolving followed to the photosensitive belt and controlling the folding of the photosensitive belt; a laser scanning unit for scanning the laser to the width wise of the photosensitive belt; and a laser sensor for accepting the laser passing through the shoe slot by scanning from the laser scanning unit.
