ELECTRONIC TIMEPIECE, HAND POSITION DETECTION CONTROL METHOD FOR ELECTRONIC TIMEPIECE, HAND POSITION DETECTION PROGRAM FOR ELECTRONIC TIMEPIECE, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an electronic timepiece capable of detecting surely a position of a hand without impairing an appearance, a hand position detection control method for the electronic timepiece, a hand position detection program, and a recording medium.;SOLUTION: A light emitting device and a photoreceiver for a hand position detector 8 are arranged in a reverse face side of a translucent dial 5. Specular parts 611, 621, 631 are formed in a reverse face side of the hand 6. Light emitted from the light emitting device is transmitted through the dial 5, is reflected by the specular parts 611, 621, 631, and is received by the photoreceiver. Since the dial 5 is translucent, the hand position detector 8 can be arranged in the reverse face side of the dial 5 not to impair the appearance of a radio-controlled timepiece 1. The light from the light emitting device is transmitted through the dial 5, because the dial 5 is translucent, to detect surely the position of the hand 6, even when the hand position detector 8 is arranged in the reverse face side of the dial 5.;COPYRIGHT: (C)2007,JPO&INPIT
