ELECTRONIC CLOCK

PROBLEM TO BE SOLVED: To provide an electronic clock that can restrain occurrence of troubles in the detection of rotation of a rotary switch and enhance the accuracy of detection.SOLUTION: An electronic clock is equipped with a rotary switch that accepts rotary operation from outside; a rotation detector that detects rotary actions of the rotary switch; a detection setting controller that prescribes the frequency of detection by the rotation detector; and an acting state determining unit that determines whether the state of action is as prescribed or not. The detection setting controller, if the state of action is as prescribed at the time of detection by the rotation detector, sets the detection frequency of rotary actions to a prescribed operation frequency or, if the state of action is not as prescribed, sets the detection frequency to a standby frequency lower than the operation frequency.SELECTED DRAWING: Figure 2 【課題】回転スイッチの回転検出上の不都合の発生を抑え、検出精度を向上させることの出来る電子時計を提供する。【解決手段】外部からの回転操作を受け付ける回転スイッチと、回転スイッチの回転動作を検出する回転検出部と、回転検出部による検出周波数を定める検出設定制御部と、所定の動作状態か否かを判別する動作状態判別部と、を備え、検出設定制御部は、回転検出部による検出時に、所定の動作状態であると判別された場合に、回転動作の検出周波数を所定の動作時周波数に定め、所定の動作状態ではないと判別された場合に、検出周波数を動作時周波数よりも低い所定の待機時周波数に設定する。【選択図】図２
