Abstract

PURPOSE:To vary the speed of a motor by a simple method and to change the density of image elements by changing the frequency dividing rate of a frequency dividing means in accordance with instructions to change the density of image elements and varying a rate of a frequency input to a phase comparing means to an output clock. CONSTITUTION:When the instruction to change the density of image elements from an external device, is issued, a system controller determines the frequency dividing rate corresponding to the density, and a programmable counter 15 sets a frequency dividing rate. Accordingly to said frequency dividing rate, control clocks are divided, input to a phase comparator circuit 12, and compared with a reference clock. The control clocks output from the circuit 12 vary in proportion to the frequency dividing rate, and consequently the control clocks of a voltage controlled oscillator 14 also vary. Said clocks are compared with an output from a motor speed detector, and a motor driving circuit is controlled to change the rotating speed of a rotating polygon mirror. Thus the density of image elements can be changed by the simple method.
