  • Patent number: 4623898
    Abstract: A manual paper feed mechanism for a printer has a release lever adapted to permit mounting and demounting of a print paper to and from a platen, a paper feed gear for rotating the paper feed roller, a manual knob having a peripheral gear section engageable with the paper feed gear, and a manual lever supporting the manual knob rotatably and swingably towards and away from the paper feed gear. In addition, the mechanism has a first cam portion formed on the manual lever, and a second cam portion engageable with the first cam portion and formed on the release lever, such that the release lever is rotated in response to the operation of the manual knob and the paper feed gear in engagement with each other. This arrangement selectively permits the manual feed of the print paper by the manuel knob.
