ABSTRACT:
A copying paper feed device for an electrostatic copier. A copying paper cassette receiving section is adapted to receive a copying paper cassette having a box-like case with a bottom plate the front end of which is biased upwardly by a spring. Within the cassette receiving section, a feed roller is mounted on a rotatable shaft that is adapted to be connected to a drive source. When the copying paper cassette is properly loaded into the cassette receiving section, the front end of the uppermost sheet of copying paper contacts the feed roller. A clutch in its operating condition links the feed roller with the drive source and in its non-operating condition permits the feed roller to freely rotate.
