英文摘要	PURPOSE:To quickly control the optical output with a simple constitution by detecting the repeat of minute change of the set value of a constant current due to an integrating circuit by a comparator and counting this detection by a counter. CONSTITUTION:A photo diode 3 detects the optical output of a laser diode 2, and a comparator 9 goes to the high level when an optical output level signal (e) exceeds a reference level Vr, and a counter 10 counts the rise of the comparator 9. The integral value of an integrating circuit 11 is reduced to reduce the output of the laser diode 2. When the counted value of the counter 10 reaches a prescribed value, an output signal (c) of a timer 8 goes to the low level, and a contact S1 is opened and a contact S2 is closed, and the integral value at this time is held in the integrating circuit 11, and the current of the laser diode 2 in a following printing period T1 is set. Thus, the constitution is simplified and the control is performed at a high speed, the variance of the optical output of the laser diode 2 is reflected on the counter speed of the counter 10 to perform the optical control uniformly.
