Abstract

PURPOSE: To obtain an ignitor, highly reliable in operation and easy to use, which is ignited without fail by a single operation employing such an arrangement that spark is produced continuously for a predetermined while until ignition is completed, automatically by a timer circuit.
CONSTITUTION: When one cock is opened, switch 79 associated with the cock is closed toward NO-terminal and capacitor 56 starts discharging via diode 62 and resistance 65. Resultantly, output of comparator 46 becomes high level and ignitor 88 is set into operation by transistor 52 and kept in operation for a predetermined while, that is, for a while when capacitor 56 continues discharging at the voltage determined by resistances 47, 48. At the same time, comparator 53 starts oscillation via resistance 55 and the oscillation waves are transmitted to a comparison circuit.
