PURPOSE:To adjust a delay time at the lighting and extinguishing of a lighting light individually by one delay section by providing two CR circuit sections whose time constant differs from each other. CONSTITUTION:The delay time is changed by a time constant of the CR circuit mounted externally in a timer section 5 is changed. Thus, the delay time from a comparison section 63 generates an L signal till the lighting light goes off is adjusted freely by varying the resistance and capacitor of the 1st CR circuit section 2. The delay time when the comparison section 63 supplies an H signal till the lighting light is lighted is adjusted freely by varying the capacitor and the resistor of the 2nd CR circuit section 4. Thus, the delay time at lighting and extinguishing state is adjusted freely by employing one timer section 5 by varying the capacitor and the resistor of the 1st CR circuit section 2 and the 2nd CR circuit section 4. |
