Abstract:
A matrix printer which is specifically adaptable for printing and the like is characterized by having a stationary print head containing a plurality of print wires which are arranged in a single row extending transversely of the direction of travel of a relatively heavy paper stock. The paper is advanced at a substantially constant rate of speed along the guide path and signals are generated in response to that advancement to activate selected ones of the print wires in the row so as to form dot-like impressions in the paper, line-by-line, as it is advanced past the print head. The density or spacing of the wires coupled with the printing speed is such that designs, alphanumeric characters, together with coded information, may be impressed upon the paper as it is continuously advanced past the print head, the code providing a means of verification of the information printed as well as to signal the end of the printing operation for each ticket. After each ticket is printed, a cutter is activated above the print head to sever the printed portion of the paper from the continuous roll, and an eject mechanism is sequentially activated to direct the severed portion into a discharge area. A loop sensor mechanism is employed in cooperation with a stripper motor to cooperate with the paper advancing means in advancing the paper at a constant rate of speed while minimizing the effects of tension or drag of the paper.
