る請求項1記載の機能時計の分針車。[Scope of Claim for Utility Model Registration] (1) A minute hand shaft, a minute hand pinion that is integrally formed on the minute hand shaft and drives the hour hand wheel via a hinoku wheel, and power from a motor via an air transmission wheel. In a clock movement that displays at least the minute time, the minute hand gear, which is formed by a minute hand gear and rotates once per hour, is connected to a fixed contact and generates a pulse signal by contacting the fixed contact. A switch mechanism consisting of a movable contact piece that performs a time signal operation, a movable cam that is swingably fixed to the minute hand shaft and that causes the movable contact piece to function by a step between a peak and a trough, and a switch mechanism that is configured such that the movable cam functions in reverse. A minute hand wheel of a functional timepiece, characterized in that a fixed cam having a curve that gently pushes up the movable contact piece from at least a neutral position to a peak position of the movable cam is integrally formed with the minute hand wheel. . (2) The functional timepiece according to claim 1, wherein the movable cam engages with the minute hand shaft and is regulated in cross-sectional position by a cam portion fixed to the minute hand shaft and the minute hand gear. minute hand wheel.
