Filed: 1983-02-04
Abstract: PURPOSE:To enhance the efficiency of the entire power source circuit by limiting a start current by a limiting resistor after starting and blocking the start current from flowing to a constant-voltage diode. CONSTITUTION:When a switch 2 is closed, a current is flowed to a constant- voltage diode 4 through a resistor 3 and a control resistor 12, and the prescribed voltage is applied to a light emitting element 13.

Accordingly, the start current is flowed, the drive circuit 6 is started, and a transistor 7 is switched. The output of the tertiary winding 10 of a transformer 8 is rectified by a diode 9. This rectified current stops the start current at the time of starting flowed to the drive circuit 6 through the element 13, and operates the drive circuit 6. The shortcircuit of the resistor 12 shortcircuited by the photoreceptor 14 is released by the stop of the start current, and the current to the constant voltage diode is limited.
