Claims (1)
テップモータと、時計本体に加わる衝撃をロータの動き
よりも十分に早い速度で検出する衝撃検知手段と、上記
衝撃検知手段の検出出力により前記駆動コイルにロータ
制動用制御パルスを印加する制御部とを有する電子時計
において、上記制動パルスが前記駆動コイルに対して衝
撃検知後一定時間断続的に印加できるようにしたことを
特徴とする電子時計。 □A step motor whose main components include a rotor, a stator, and a drive coil, an impact detection means that detects an impact applied to the watch body at a speed sufficiently faster than the movement of the rotor, and a drive using the detection output of the impact detection means. 1. An electronic timepiece comprising a control section for applying a rotor braking control pulse to a coil, characterized in that the braking pulse can be intermittently applied to the drive coil for a certain period of time after an impact is detected. □
