Abstract

PURPOSE: To enable the pressure plate to be surely stopped at the specified angle of inclination of specified plural angles of inclination by providing springs between cams and end parts of hinge members and making use of the elastic force of the springs and the resistance force of the cams and rollers.
CONSTITUTION: Hinge members 2 are fixed to the end part of a pressure plate 1 and the rear end parts of the hinge members 2 are turnably supported to the horizontal shaft 4 fixed to the support shaft 7 provided to the copying machine body. A cam 9 is turnably-supported to the shaft 8 fixed to the intermediate part of each hinge member 2 and turning force is applied to the cam 9 by the elastic force of spring 10. A roller 14 is provided to the shaft 13 fixed in the position aside from the horizontal shaft 4 of the support shaft 7 and the turning of the cam 9 is detained by this roller 14. Although the moment by the owing weight of the pressure plate 1 acts thereto, the pressure plate 1 is stopped by the elastic force of the springs 10 and the resistance force of the cams 9 and rollers 14.
