Abstract

PURPOSE: To control the opening speed of an original document pressing plate with a damper and carry out a smooth operation of opening and closing by causing the energy in the opening direction to act upon the document pressing plate, and automatically opening the document pressing plate with only a releasing operation which unlocks a locking member which locks the above energy in the closed state.
CONSTITUTION: Shaft 5 of the flange 4 secured to original document pressing plate 1 is rotatably mounted on cylinder 6 so that pressing plate 1 can be freely opened and closed. One end of wire spring 12 disposed at one end of the shaft 5 is locked by stop pin 13 of the flange 4 while the other end is locked by metal fitting 8 of the cylinder 6 such that the document pressing plate 1 is energized in the direction of the arrow A or opening direction. The rotation of the shaft 5 is limited by arm 14. Shaft 15 is rotated by arcuated rack 19 secured to the flange 4 via pinion 17. Clamp unit is formed the recess of cam plate 16 secured to the shaft 15 and the claw energized by spring. The shaft 5 is provided with vane wheel or impeller and its outer circumference is caused to be in sliding contact with the inner wall of the cylinder 6, thus the damper operation is carried out by the revolution of shaft 5.
