Abstract

PURPOSE: To let the pressure plate be surely stopped at an arbitrary angle of inclination by making use of the friction force when sliding pieces relatively move while making contact with receiving members and the force of springs applied to the sliding pieces at the opening and closing of the pressure plate.
CONSTITUTION: Hinge members 2 are fixed to the end part of a pressure plate 1. The rear ends of the hinge members 2 are turnably supported to the horizontal shaft 3 which is fixed to the support members provided to the copying machine body. Receiving members 7 and sliding pieces 10 to be pressed to this receiving member 7 by springs 9 are provided to the abovementioned support members and hinge members 2 and are so constituted that the sliding pieces 10 move relatively while making contact with the receiving members 7 at the opening and closing of the pressure plate. If with such constitution the pressure plate 1 is turned upward about the horizontal shaft 3 by holding its grip, then the hinge members 2 turn as well and along with this, the springs 9 and sliding pieces 10 also turn, thereby making it possible to stop the pressure plate 1 at an arbitrary angle of inclination.
