COPYING MACHINE |
摘要 |
A copying system including a pivotal document feeder disposed above the original document platen and a pivotal plate disposed along an edge of the platen. The pivotal plate functions as a reference edge to manually align documents on the platen. A control device is provided to inhibit operation of the document feeder when the plate is on the document platen or when a paper jam occurs. The device includes a nonreflective patch disposed on one surface of the plate. A reflective patch is disposed within the paper path. A photosensitive detecting assembly is disposed in spaced alignment with the paper path. When the plate is on the document platen, the photosensitive detecting assembly coacts with the reflective patch to generate a signal which inhibits operation of the document feeder. The photosensitive detector assembly coacts with the nonreflective patch to enable operation of the document feeder and to function as a paper jam detector. |
