Abstract
A supporting mechanism of a document cover lid to be used for a copying apparatus includes a base of a supporting member mounted to the upper portion of an apparatus housing so as to swing about a horizontal axis. A positioning member is mounted on one of either the apparatus housing or the supporting member has a first frictional surface which is a circular periphery in a vertical plane with respect to the horizontal axis. A contact member is mounted on the other of either the apparatus housing or the supporting member and, has a second frictional surface, which is a circular periphery in a vertical plane with respect to the horizontal axis and is elastically pushed against the first frictional surface. By this mechanism, it is possible to support the document cover lid in an opened position upwardly at an angle sufficient to replace an original document.
