Abstract
A drive system for processing passbook data includes a bi-directional stepper motor responsive to programmed input signals, cam sets rotated by the stepper motor for initiating data sensing, document positioning, and data transfer operations, and cam followers actuated by the contour of their associated rotating cam sets for moving their reacting components to perform those operations. Appropriate cam followers cause a pressure plate and sensor to move toward and sense coded data on a document, a gate to open and close to position the document for further processing, and a print platen to advance toward the document, provide a backing during data transfer, and then retract.
Claims6
A drive system for processing passbook data comprising:
- an incremental drive for actuating the system;
- means for controlling the incremental drive;
- a first rotatable cam set;
- means for sensing data on a document;
- first means for following the configuration of the first rotatable cam set to position the sensing means;
- a second rotatable cam set;
- means for positioning the documents;
- second means for following the configuration of the second rotatable cam set to actuate the document positioning means;
- a third rotatable cam set;
- means for backing the document during data transfer to the document;
- and
- third means for following the configuration of the third rotatable cam set to properly place the means for backing the document during data transfer to the document.
