ログ時計の修正回路。[Claims for Utility Model Registration] A reference signal generator that generates a reference signal; a frequency divider that divides the frequency of the reference signal from the reference signal generator and outputs a normal drive pulse signal and a correction pulse signal; A forward direction correction switch, a reverse direction correction switch, a switching circuit that outputs a correction pulse signal instead of a normal drive pulse only when the forward direction switch and the reverse direction switch are operated, and a pulse signal from this switching circuit. A shift register that shifts the generation of output signals from a plurality of output terminals in a fixed direction in response to the occurrence of the shift register, and whose shift direction is reversed when a reverse correction switch is operated; and a shift register that is rotationally driven by the output signal from this shift register. and a polyphase motor, wherein the frequency divider is configured to output a correction fast-forward pulse signal faster than the correction pulse signal, and further, the switching circuit operates a correction switch in the opposite direction. a first gate circuit that outputs a correction fast-forward pulse signal from the frequency divider in response to a forward correction switch operation; a second gate circuit that outputs the correction pulse signal in response to a forward correction switch operation; A correction circuit for an analog timepiece, comprising: a third gate circuit that outputs the normal drive pulse signal when the switch is not operated.
