Claims (1)
毎に発生する通常駆動信号とは異なる警告駆動信号を発
生する警告駆動信号発生回路と、前記通常駆動信号と前
記警告駆動信号を選択して通過させる選択回路と、前記
通常駆動信号による駆動時にステップモータのロータの
回転、非回転を検出する検出回路と、この検出回路が前
記ロータの非回転を検出すると前記警告駆動信号を通過
させ、外部操作部材を操作することにより前記通常駆動
信号を切換通過させるべ（前記選択回路を制御する制御
回路とを設けたことを特徴とする電子時計。゛ In an electronic watch having a step motor, a warning drive signal generation circuit generates a warning drive signal different from a normal drive signal that is generated at regular intervals, and the normal drive signal and the warning drive signal are selected and passed through. a detection circuit that detects rotation or non-rotation of the rotor of the step motor when driven by the normal drive signal; and when this detection circuit detects non-rotation of the rotor, it passes the warning drive signal and triggers an external operation. An electronic timepiece characterized in that the normal drive signal is switched and passed by operating a member (and a control circuit for controlling the selection circuit).
