ABSTRACT:
The present invention relates to an original holding plate hinging mechanism for a copying machine, a printing machine or the like. When a thick solid original, such as a book, needs to be covered with an original holding plate, the pivotal point of the original holding plate is raised so that the original holding plate is placed practically horizontally on the thick solid original when closed. The original holding plate hinging mechanism comprises a supporting member attached rotatably to a member of the copying machine, an original holding plate joined at the rear end thereof to the free end of the supporting member so as to turn relatively to the supporting member, and a resilient means interlocked with both a member of the copying machine and the supporting member to control the torque for turning the supporting member.
According to the present invention, the mechanism further includes a control means interlocked with both the supporting member and the original holding plate to control the turning motion of the original holding plate relative to the supporting member.
