Abstract

PURPOSE: To obtain the timing signals necessary for both the speed control and print control of a printer driving motor, by producing the prescribed output voltage when the output of a tachogenerator is zero.
CONSTITUTION: The base-emitter voltage of the transistor TR12 is set identical to that of the TR11 when the voltage of the output winding 1 of the tachogenerator is zero. At the same time the 1/2 error between the power sources 18 and 19 is obtained at the output 10 when the value of the resistor 17 is set to 1/2 the value of the resistor 16 to be applied to the logic circuit. The logic circuit produces the timing signal when the output voltage of the tachogenerator is zero.
