Abstract
PURPOSE: To perform both the high-speed half-dot printing and the normal printing without switching the driver circuit, by combining two timers and then setting the two timing.
CONSTITUTION: Both the 1st and 2nd timers 7 and 9 operate by the print signal, and the print command signals featuring the different timing are supplied to both timers. And the compensation is secured to the ample application time in order to form the dot. Thus the half-dot printing becomes possible. In the case of the half- dot printing, SRFF2 is set by the fall of print pulse 2, and solenoid 13 is sucked. And gate 6 is opened since timer 7 is under operation, and thus timer 9 is triggered. And the electric conduction of solenoid 13 is cut off after the set time.
