め、薄形化を図る技術として満足なものではなかった。[Prior Art and its Problems] Conventionally, as a needle-turning device for a thin timepiece, it is known that a needle-turning knob inserted on the back surface of a machine body is rotated while being pressed by a finger (for example, actual opening). 57-4774 publication). The needle-turning knob is attached to the needle-turning shaft that integrally has a pinion portion that penetrates a through hole formed in the upper case of the machine body and meshes with one of the train wheels arranged inside the machine body. It is connected. However, this structure has a problem that it is difficult to reduce the thickness of the timepiece mechanical body. Therefore, as a technique for reducing the thickness of the timepiece mechanical body, a minute hand pipe in which a minute hand gear is slipperably fitted is projected from the counter pointer side main plate of the movement case, and this protruding portion is used as a knob portion to form the minute hand gear of the minute hand pipe. A timepiece for a timepiece having a flange portion which is larger than the outer diameter of the protruding portion and contacts the counter pointer side main plate between the counter pointer side main plate and the counter pointer side main plate of the protruding portion is formed on the concave surface. The mechanism was disclosed by Japanese Utility Model Publication No. 58-160371. However, even in the second prior art, the knob portion is projected from the counter pointer side base plate of the movement case, which is not satisfactory as a technique for achieving a thin shape.

あるという優れた効果がある。[Effects] As described above, the hand-turning structure of the thin timepiece of the present invention is a hand-turning device that is formed separately from the minute hand wheel and that meshes with the day back wheel provided between the upper case and the lower case. It has a needle-turning structure that rotates the gears to correct the time.The needle-turning gear is formed in a flat shape, and the center of the upper surface of the needle-turning gear is fitted into a through hole formed in the upper case to expose the outside. A protrusion having a groove for turning the needle is formed, the upper surface of the protrusion is formed to be substantially flush with the upper surface of the upper case, and the lower case is provided on the rear surface of the needle turning gear. Since the shaft portion that fits into the recess is formed, the timepiece mechanical body can be made extremely thin. Further, since the groove is formed so that a coin-shaped member can be inserted therein, there is an excellent effect that the hand-turning operation is easy even though it is a thin timepiece mechanical body.
