Copying apparatus equipped with an original-support device, and an original-holding mechanism therefor

摘要

A copying apparatus of the type in which an original-support device is mounted reciprocably on a housing through a sliding mechanism. The sliding mechanism is comprised of an outside rail fixed to one of the original-support device and the housing, an inside rail fixed to the other of said original-support device and housing, and disposed between the outside and inside rails, a holding plate rotatably holding a plurality of balls which contact both of the outside and inside rails. Each of the opposite ends of one of the outside and inside rails has disposed thereat a stop face against which each of the opposite ends of the holding plate can abut, and one end portion of the other of said outside and inside rails has disposed thereat a stop face against which one end of the holding plate can abut. A stop member defining a stop face against which the other end of the holding plate can abut is detachably disposed at the other end portion of the other of said outside and inside rails. An original-holding mechanism for an original-support device is also disclosed which includes a flexible holding member for covering an original document placed on a transparent plate and rigid supporting member located outwardly of the original-holding member. One end edge portion of the original-holding member is mounted adjacent to one end edge of the transparent plate. The base portion of the supporting member is mounted for pivotal movement about an axis extending along said one edge of the transparent plate as a center. The free end edge portion of the original-holding member is connected to the free end portion of the supporting member for movement over a predetermined range in a direction perpendicular to said axis.
