<p>PURPOSE: To reoperate a designated time-informing function without necessity of a complicated operation after a power supply is restarted. CONSTITUTION: When a new battery pack 7 is mounted and a present time is input by a key input unit 4 in the state that the power supply to a real time clock 1 by a battery pack 7 or a clock backup battery 8 is interrupted, a controller 3 reads the informing request time from a nonvolatile memory 5, and compares the request time with the present time counted by a counter 2. If it is judged that the present time does not pass the request time, the counter 2 starts counting using a reference clock generated by the real clock time 1, and the counter 2 performs the writing function in the memory 5 when the counted value counted by the counter 2 coincides with the time difference data.</p> |
