Abstract
PURPOSE: To prevent an overload on a printing element driving part by detecting the number of times of operations assigned to the printing element driving part and by varying a driving period according to the number of times.
CONSTITUTION: Print information is stored in line buffer LB and occupancy operation detector DD detects the number of times of print operations for one line. When the number of times is greater than an estimated value, an output is supplied to printing-element driving period setting circuit DPC. By a DPC output, space motor speed calculation circuit SMS is operated to calculate a rotation speed and through motor driver circuit SMD, space motor SM is driven. Here, SD is a speed detector generating a feedback signal for motor speed stabilization and at the same time, a signal corresponding to the speed of motor SM, i.e. variation in the moving speed of a carrier is supplied to electromagnet driver circuit MGD of the print operation driving part. Consequently, an overload on the printing element driving part can be avoided.
