PURPOSE:To interrupt the time count of a timer when an interrupting means is operated by providing an interrupting signal generating means and an interrupting means operating part to output a signal so that the interrupting means can be operated by a signal from the interrupting signal generating means. CONSTITUTION:For a gas interrupting device, the time count of a timer 10 is started when an activating signal impressing means 6 is operated. Then, while gas is used according to a normal use pattern, the gas use pattern during such a period is measured by the operation of a use condition storing and calculating part 7. When a gas use condition gets out of a suitable use condition and the interrupting means is operated, the time count of the timer 10 is interrupted. Then, when an interrupting means 9 is returned, the time measurement of the timer is restarted. Further, when an interrupting condition is obtained at a time point that an activating signal is generated, operation waits for the return of the interrupting means 9 and the time count of the timer is started. |
