Abstract

PURPOSE:To beforehand indicate that the life a battery is ceasing, by outputting and displaying an intense driving signal from an electronic circuit when a mechanical part does not operate normally corresponding to an electric driving signal. CONSTITUTION:A motor operation detecting circuit M-DET detects a rotor 2 failing in rotation although a driving pulse is outputted from a motor driving circuit DRV, and then informs a pulse-width control circuit P-CTR and a hand-advance control circuit S-CTR of that. The P-CTR, on receiving the signal, sends a signal to the DRV, which outputs driving pulses, having greater pulse width than that of ordinary pulse driving pulses, continuously to put a motor in operation. On receiving the signal from the M-DET, the S-CRT also changes a hand advancing method into a two-second advance, two-second stop mode to beforehand indicate that the life of a battery is ceasing. This constitution beforehand indicates the ceasing of the battery life.
