Abstract

PURPOSE: To carry out a position control in accordance with the processing speed of the computer, by performing the control of the once-clock at the beginning of the rotation for the positioning device of the printer's print head and then switching the control to that of the twice-clock in order to eliminate the variation of the changing point of the velocity level which is caused by the input level.
CONSTITUTION: The initial setting of the shift extent input data of the moving object, and then the velocity level of the once-clock is delivered through velocity level converting circuit 172. Thus the servomotor is driven by servocontrol circuit 11 at the velocity level of the motor. After this, the sensor signal showing the shift extent of the moving object and supplied from the sensor is supplied to FF12 and 13 forming the 2-bit counter and via amplifier 10. Then the contents of counter 171 are subtracted with every several times of the clock signal, and at the same time the subtracting ratio of counter 171 is varied at the beginning of the motor's rotation and based on the initial value of the shift extent of the moving object. Thus the variation of the changing point of the velocity level caused by the input level can be pevented in order to ensure a high-precision positioning in accordance with the processing speed of the computer.
