Printer control assembly

Abstract

A small sized printer wherein the duration of the print cycle and the sequence of printing operations, during a print cycle, is controlled. The printer includes a plurality of print characters circumferentially disposed therearound, the print characters being selectively positioned in a print position by rotating the print ring from a rest position to a print position during each print cycle. A motor is adapted to be energized to rotate the print rings from a rest position to a print position during each print cycle. The instant invention is particularly characterized by a detection arrangement for detecting the rotary position of the print rings and generating a character selection timing signal representative of each of the rotational positions of the print ring. A print selection arrangement is associated with each of the print rings for selectively positioning same at predetermined print positions during each print cycle in response to the character selection timing signal produced by the detection arrangement being applied thereto. The detection arrangement is further adapted to detect the rotary position of the print rings and generate a reference signal that is distinct from the character position timing signal produced during each print cycle, the motor being utilized to rotatably drive the print rings being deenergized in response to the reference signal being applied thereto.
