Abstract
PURPOSE: To secure setting of the uniform and steady scanning region as well as the high-speed scanning for the scanner element by using the control pulse for the mechanical scanning such as the facsimile or the like so that the advance cumulative error may be minimized for the pulse motor.
CONSTITUTION: Scanner element 1 to which the reading or recording head is mounted moves back and forth by the stretching force of wire 3 on guide rail 2, and the scanning limit signal is delivered when element 1 passes through the positions of scanning limiter 9 and 10. Pulse motor 8 is controlled via driving circuit 19 and based on the control pulse supplied from the control circuit comprising oscillator 11, divider 12, division ratio control part 16 and others. Thus, the high-speed scanning becomes possible. In this case, the division ratio at each step of divider 12 is set so that the advance cumulative error of motor 8 may be minimized and furthermore the optimum frequency and the pulse number may be given to the motor to drive the motor with the pulse number row corresponding to the desired scanning speed.
