Electronic apparatus, method for detecting positions of pointer members in electronic apparatus, and a program for detecting positions of pointer members in electronic apparatus

摘要

A timepiece 1 includes pointers 2, motors 21 and 26 for driving the pointers 2, a pointer position detector 405 for detecting the positions of the pointers 2, a control unit 409, an electricity storage unit 40 as a power supply, and a voltage detector 408 for detecting the power supply voltage. The control unit 409 controls the pointer position detecting operation by means of the pointer position detector 405 on the basis of the power supply voltage detected by the voltage detector 408. Therefore, the pointer position detector 405 can be halted when the power supply voltage decreases to less than a specific voltage, and the pointer position detector 405 can be driven while the power supply voltage is low.
