噛合状態になく針合せと同時に曜修正されることはない
。When the small iron wheel 8 rotates, the correction wheel 10 also rotates, but when the flat iron lever rotates, the correction wheel is rotated by the lever action of the swing regulating lever 13, which is loosely fitted into a pin on the main plate and engages with the flat iron lever. Since it is moved toward the outer periphery of the main plate, it is not in mesh with the day correction transmission wheel 15, and the day is not corrected at the same time as the hands are set.
この様な従来の形式は平鉄レバー上に前述の回転トルク
を発生するバネ部材がないためオシドリと平鉄レバーの
係合を本発明による長穴にする必要はなく又、カンヌキ
バネの作用で平鉄レバーを作動させる如くしたとしても
伺ら問題はない。In such a conventional type, there is no spring member on the flat iron lever that generates the above-mentioned rotational torque, so there is no need to use the elongated hole of the present invention for engagement between the mandrel and the flat iron lever. There is no problem even if the iron lever is activated.
