Abstract
PURPOSE:To realize a timer device having a comparatively long time even with a small time constant of a charging circuit, by charging the square wave voltage to drive a timer circuit. CONSTITUTION:A square wave output (a) given from a square wave oscillator 8 is rectifed by a diode 7, and only the DC component is applied to a resistance 2 to charge a capacitor 3. The both-end voltage of the capacitor 3 is applied to a inverting circuit 5. As the voltage value of an integral output (b) does not increase during a nonoutput period of the output (a), the timer time can be extended by an amount equivalent to the nonoutput period of the output (a).
