Abstract
PURPOSE:To provide the starting timing of an integrating circuit to prevent a malfunction, by a method wherein a voltage at a charging power supply is applied to an integrating circuit via a waveform shaping circuit when a switch means is conducted to allow a reference voltage to rise and a capacitor is charged at a charging voltage which is in proportion to the reference voltage. CONSTITUTION:When an on-signal is supplied to a switch 4 from a driving circuit 6, a capacitor 3 is discharged to momentarily pass a large current to a laser tube 5. This abruptly reduces the output voltage of a detection circuit 8 to zero to generate a pulse waveform at an output point C of a waveform shaping circuit 13. A capacitor C1 in an integrating circuit 12 is charged by a reference voltage power supply 11. An output pulse from the circuit 13 is fed to the base of a transistor Q1 to decrease the charging charge of the capacitor C1 to a low level, at which charging is started to again raise the output voltage of the integrating circuit 12. A comparator 10 compares this output voltage with a detection voltage from the detection circuit 8, and a generated error signal is supplied to a charging power supply 1. The signal is allowed to rise as an output in proportion to the reference voltage to obtain required capacitor charging characteristics.
