イッチ３６が閉放されることになる。At this time, the engagement time between the short arm 31 of the operating lever 30 and the notch γ of the cam portion 8 of the second hand wheel 3 is several seconds (see FIG. 6C).
The engagement time between the pin 32 of the long arm 33 and the notch 16 or 1T of the cam portion 18 is approximately 1 minute (see Figure 6), and the engagement time between the short arm 3γ and the notch 2T of the cam portion 28 is approximately 4 minutes. Minutes (
(see Fig. 6C), and further, approximately 30 seconds before the short arm 31 engages the notch T, the pin 32 is inserted into the notch 16 or 1γ.
and so that the short arm 3γ engages in the notch 21 about 2 minutes before the engagement of the short arm 31, the pin 32, and the short arm 3γ with the notch γ, 16 or 1T, and the notch 21. If the minute and second hands are set to the hour, for example, 12 o'clock, the reed switch 36 will always be closed when the minute and second hands reach 12 o'clock.

リップを起して伝えギア１０は回転しない。For example, when the minute wheel 25 is rotated via the needle rotation shaft 38, the transmission wheel main body 14 is
It rotates in 8 rotation increments, but the transmission gear 10 and the transmission wheel body 1
4 is connected to the stage clutch in a slippable manner, so slipping occurs and the transmission gear 10 does not rotate.

従って秒針車３は針回し軸３８の整時動作に無関係に回
転し、運針する。Therefore, the second hand wheel 3 rotates and moves regardless of the timing operation of the hand rotating shaft 38.
