LIFTING DEVICE FOR KNOCK-UP PLATE OF PRINTER

摘要

PURPOSE: A lifting device for a knock-up plate is provided to reduce the thickness of a printer body and to improve the external by removing the protruding part outward. CONSTITUTION: A protrusion of a lift gear(110) is contacted with a slant face(301) of a plate spring(300) and the lift gear lifts up on the slant face to be butted into a relay gear(310). The plate gear smoothly moves by elasticity to rotate the lift gear without force. When the relay gear and the lift gear are combined, a driving motor is operated to rotate the lift gear and the rotating force is delivered to a shaft(130) through a lift holder and then a knock-up plate is lifted by the rotation of a lift lever(150).
