摘要： A printing apparatus which includes a single revolution clutch. The clutch includes first and second cam sections which comprise the output member of the clutch. When the clutch is released, a spring accelerates the output member to bring a control surface on the second cam section into operative engagement with a cylindrically-shaped, rotating, input member. An abutment member on the first cam section cooperates with a follower arm to stop the rotation of the output member after a single revolution. A solenoid and linkage are used to raise the follower above the abutment stop to release the clutch for another single revolution of the output member.

摘要： An imager for imaging a document moving in a document track in a table top document processing machine. The imager includes a housing which is made of several portions which are designed to be assembled quickly with a minimum of fasteners. A first line of green LEDs and a second line of red LEDs are located in the housing to illuminate a scanning line from which image data about the document is obtained by an optical system including a CCDs. The imager is also designed so that the same imager can be used on either side of the document track to image the front or back of the document. When two such imagers are used, a white reference member (for calibrating the imager to ensure repeatable and uniform data) located in one of the imagers is used by the other imager.
