Abstract
PURPOSE: To simply compensate the dot shift through the adjustment of the delay time by makihg adjustable the phase relationship between printing start signals and printing synchronous signals.
CONSTITUTION: An adjustable delay circuit 18 is inserted into the output line of printing start signals or printing synchronous signals to make adjustable the phase relationship between the two signals so that the dot shift may be compensated by the adjustment of the dalay time of the delay circuit. This adjustable delay circuit is composed of a adjustable monostable multivibrator VMM and a gate AND 2. The outputs of photosensors 141 and 142 and 17 are subjected to pulse-shaping process so that start signals 141S, end signals 142 and printing synchronous pulses 17S can be generated. The monostalbe multivibrator MM is used to shorten the pulse width of the printing synchronous pulses the more than the output pulses of the sensor 17 so that the dot shift upon the printing start may be reduced.
