PURPOSE:To provide a reporting function controlled and driven by a device and to display digitally the time by means of the operation of a clock device by installing a time display part, a clock device and a battery power source within the timer main frame case. CONSTITUTION:The time display part 1, the clock device 8 and the battery power source 9 for the clock device are built within the timer main frame case 5. In such a way as this, once the time is set, the repeated operation is feasible every day, and the time up reporting can be performed independently without connection to the wall receptacle and the simplification of kinds of assembly during the manufacture is feasible without relation to the power source frequencies such as 50Hz and 60Hz. Further, even when it is in the service interruption, the clock device 8 operates which makes the time reporting feasible and when the service is restored from interruption, the normal timer operation is obtained. |
