Abstract
PURPOSE: To improve an effective printing speed with reduction of non-printing frequency for detecting an ink ribbon terminal by a system wherein the reversal of an ink ribbon running direction is operated after completing the printing cycle.
CONSTITUTION: Whenever a switch 1 is detecting an ink ribbon terminal, a flip- flop 2 is setting alternately or resetting, the monomultivibrator 6 (time constant T1 is corresponding to the time required from the terminal detection up-to completing the printing cycle) is triggered by opening NOR gate 5 of 1 side output and 0 side output by means of the differentiation circuits 3, 4. 1 Side output of D-type flip- flop 11 is turning reversely whenever the switch 1 is detecting, which energizes or deenergizes relay coil 14 alternately to turn reversely the running direction of the ink ribbon. Monomultivibrator 12 allows 0 side output thereof to apply to the printer control unit for stopping the printing operation during the time corresponding to the time constant T2.
