Abstract
Abstract A photographic copying apparatus is provided with a document holder for carrying different size documents which are to be copied. The document holder is supported on the copying apparatus for movement between a document copying position and a document loading and unloading position. An easel mechanism, mounted on the document holder, includes a plurality of easel members which cooperate to frame an area occupied by a document. At least one of the easel members is movable to vary the size of such area for accommodating different size documents. An easel locking device restrains at least one of the easel members from movement to vary the size of the area framed thereby, in response to movement of the document holder out of the document loading and unloading position, and releases at least one of the easel members for movement to vary the size of such area, in response to movement of the document holder into the document loading and unloading position.
