Abstract
PURPOSE: To control the print head constantly and quickly against any fluctuation in the load and voltage by means of a speed sensor and a DC motor speed control circuit.
CONSTITUTION: A frequency signal is obtained from a pick up 7 in proportion to the movement speed of a print head 4 and amplified with an amplifier 11 to produce a signal 1. The peak of the signal 1 is determined with a peak detector 12 and the output 2 serves as a printing timing signal. A signal 2 is applied to a retriggering timer 22 to produce the output 3. A flip block 23 receives a signal 3 and outputs a signal at H a level if the signal 3 at a L level or at a L level if at a H level when the signal 2 is inputted. The signal 4 is impressed on a transistor in such a manner that the transistor is turned on at the H level. The input signal 5 to a comparator 14 is divided in the voltage when the transistor is on while remains intact when it is off.
