Abstract
PURPOSE: To miniaturize a power-source panel and print any desired dot pattern without limitations by a method wherein a power-source voltage for driving printing hammers is monitored, and the printing and paper-feeding actions in the next printing cycle are stopped when the monitored voltage is lower than a preset voltage.
CONSTITUTION: A plurality of hammer coils L1WLn connected in series with switching transistors T1WTn of a hammer driving circuit 3 are connected in parallel with a power source, and the power-source voltage V is fed into an inverted input terminal of a comparator 5 in a power-source voltage monitoring circuit 4. On the other hand, a non-inverted input terminal of the comparator 5 is fed with the constantly preset voltage obtained by dividing a reference voltage VR between resistances R1, R2, so that the comparator 5 outputs a HIGH-signal or a LOW- signal according as the voltage V is lower or higher than the preset voltage. When the LOW-signal is outputted, the circuit 3 performs printing. On the other hand, when the HIGH-signal is outputted, printing and paper feeding actions are stopped.
