く加工で複雑でコストが高い等の欠点があつた。 In order to adjust the time rate of electronic clocks that have conventionally used a crystal oscillator as a time standard source, the so-called logical adjustment method, which adds or subtracts several pulses to a clock signal within a certain period of time, is increasingly being used. It is persistent. An example of the structure of such a timepiece is JP-A-54-155869, in which a circuit pattern connected from multiple logical adjustment terminals on an IC is arranged around the adjustment switch shaft, and two springs fixed to the adjustment switch shaft are used. When a flexible arm is brought into contact with a pattern and the speed/speed switch is rotated, the combination of the plurality of circuit patterns can be changed to perform multi-step logical speed/speed control. The disadvantages are that the space for the lever to rotate is large, and that there are many components required to rotatably fix the switch lever to the circuit block with a certain torque, resulting in complicated machining and high cost.

In FIGS. 2 and 3, an oshidori shaft 2, which is a shaft member fixed to the base plate 1, which is the base frame of the watch body, is connected to an oshidori shaft 2, which is one of the switching members that engages with a winding stem 3, which is an external operating member. are fitted, and the dowel is elastically pressed against the base plate side of the bolt presser foot 5, and the positioning in the plane rotation direction is also performed using the dowel 4a and the click part 5a.
It will be held in A small iron wheel seat 6 is placed between the main plate and the iron wheel, which determines the height of the iron wheel, and also serves as a bearing for the winding stem 3, a bearing for the small iron wheel 7, etc. 8 is a circuit board consisting of an insulating layer and a conductive layer; 9 is a circuit board 8

たため、緩急構造によるスペースの増加がない。 The first embodiment of the present invention is constructed as described above, and compared to the conventional example described above in which the speed/speed switch is attached independently to the circuit block, the shaft member of the switching section is extended to the top surface of the watch body, and this shaft member is extended to the upper surface of the watch body. Since the speed switch is held in common, there is no need for a pin for mounting and caulking, and there is no need to provide a separate pin on the base plate. In order to simplify the machining of the main plate, it is important to have a structure with fewer sidewalls and pin stands, but in this example, the switching member is arranged from the back side to the front side, where conventionally there were many, and the circuit section is arranged clockwise. It is placed on the upper part of the body, and it is overlapped with the switching part in a plane, and the shaft is extended to the circuit part. The associated hole position management, etc., is omitted. These rotary speed/speed switches come into contact with the circuit board with elasticity, so the arm must be long to improve the springiness, which increases the overall length. Since a large number of wires must be wired around the pattern, a large flat space is required, and circuit boards such as small clocks, clocks that use multiple motors, and so-called hybrid clocks that combine digital parts are used. However, this was a major obstacle to adoption in watches that require complicated wiring. In analog watches, a switching member such as an oshidori that is linked to the winding stem is necessary, and it is a relatively large part that rotates when the winding stem is operated and can be subjected to large external forces. For,
Although a large planar space is required inside the watch, this invention utilizes this planar space effectively, so there is no increase in space due to the adjustment structure.

でき確実な緩急ができる。 FIG. 4 shows a second embodiment of the present invention, which is an improvement over the first embodiment to ensure reliable rotational positioning of the speed/speed switch. In the circuit board 8 shown in FIG. 4, a plurality of logic patterns 8b are wired around a speed/speed hole 8a, and a hole 8c is provided corresponding to the stop position of the speed/speed switch 9 shown by the imaginary line. Since the second embodiment has such a configuration, when the adjustment switch is rotated and the contact portion at the tip of the adjustment switch engages with the hole 8c, a click is felt, allowing accurate adjustment of the adjustment switch position. It is something that can be done. In the first embodiment, the adjustment switch is aligned with the adjustment scale engraved on the circuit receiver 11, but the circuit receiver and the circuit board 8
The adjustment pattern 8b and the adjustment scale of the circuit receiver may be misaligned, and due to the misalignment of the contact part of the adjustment switch, play in the center hole 9a, etc., even if the adjustment pattern 8b is set to the adjustment scale, the desired adjustment cannot be achieved. There was something I couldn't do. The second embodiment solves these drawbacks with a simple structure and improves the feel of the speed and speed. In addition, the hole 8c should be set so that the contact part of the speed/speed switch does not fall completely, and it is effective even if only one side of the contact point is used, and it may be a notch shape instead of a hole. Even if a shaped part is formed, a click feeling can be obtained and reliable speeding can be achieved.

型化、ローコスト化に大きな効果がある。 FIG. 5 shows a third embodiment of the present invention. A speed switch 9 is coaxially engaged with the push shaft 2 with which the shift switch 4 is engaged, the end of the speed switch is pressed against the circuit board 8, and the circuit support 11 is holding down the circuit board. The speed/speed switch is located between the circuit board and the brake pad, and is configured to push them together using a spring force. For this reason, the third embodiment does not require the bar holder 5 for holding down the rear end, and is highly effective in making the watch thinner, smaller, and lower in cost.

きいものである。 FIG. 6 shows a fourth embodiment of the present invention. A spring portion 12e provided on the changeover switch lever 12 pushes up the speed switch 9, which is supported on the shift shaft 2, toward the circuit board 8. Compared to the first embodiment, the speed switch 9 can be made into a rigid body, so the shape is simpler, and since it is a flat plate that does not bend and can be made thicker, it is easier to adjust the speed and speed, and no spring is required, so the length of the speed and speed switch can be shortened. As a result, the plane space for adjusting the speed can be further reduced, which is highly effective for women's watches and the like.

しておしどり軸２を用いてある。 In this embodiment, a winding stem 3 is used as an external operating member, a shifter 4 is used as a switching member, and a shifter shaft 2 is used as a shaft member.

る。 As described above, in the present invention, the switching member and a part of the circuit board are overlapped two-dimensionally, and the shaft on which the speed-up/down switch rotates and the rotation at which the switching part engages are both shared by the same axis. This eliminates the need for a dedicated pin for mounting the main plate, simplifies the processing of the main plate, and eliminates parts, and the speed switch can also be brought into contact with the circuit board with sufficient elasticity. Furthermore, it takes up less space and can be miniaturized.
