Filed: 1977-11-16
Abstract: PURPOSE: To ensure the setting for a even and stable effective scanning width by generating the frequency of the control pulse with which the advance cumulative error of the pulse motor becomes minimum via the programable divider.  
     CONSTITUTION: Original pulse oscillator 11 oscillates the reference clock signal and divides it through divider 12 to then transmit it to pulse counting circuit 13, thus counting the supplied pulse signals. With this count value, the advance cumulative error of motor 8 is made minimum in consideration of the action characteristics of the rotor and stator or the like of motor 8. At the same time, the control pulse corresponding to the desired scanning speed is generated through programable divider 12. As a result, the frequency is varied gradually and in a digital way during the reciprocal course of the motor to secure the automatic and stable stoppage and the high-speed reciprocal motion for the scanner. In this way, an even and stable effective scanning width can be set.
