As a known structure in which the guide axis is rotated together with the windshield by manual operation of the windshield, for example,
There is a technique disclosed in Publication No. 38870. In this structure, the windshield consists of a circular transparent part on the top surface (through which you can see the time display surface), a short cylindrical part on the side (knurling is provided at the corner part to make it easier to put your fingers on it), and this cylindrical part. The flange part of the windshield is elastically held between the case, which has a flange part extending outward from the lower part, and a hole through which the knurled part of the windshield protrudes, and a member fixed inside the case. It is rotatable. In addition, the tip of the guide needle fixed to the guide shaft of the guide wheel of the watch movement engages with the notch on the lower end of the inner peripheral surface of the cylindrical part of the windshield, so if you grasp the knurled part of the windshield with your hand and turn it, the guide needle The rotational force is transmitted from the to the reference car,
Alarm set time can be manipulated.

わせるものである。 As a second conventional example, there is a known technique disclosed in Utility Model Application No. 53-27079 (Utility Model Application No. 54-130463) in which an index mechanism is incorporated into the guideline setting mechanism to improve the precision of the set time. In this structure, a ring with an internal rotary gear is removably attached to the lower part of the internal rotary ring with a reference mark, and the teeth of this internal gear and the drive housed in the space under the dial suspended by the dial support ring It engages the wheel (which transmits the rotational force of the winding stem to the inner ring) and the jump control lever, respectively.

転ベゼルをインデツクスするものである。 Although it is not a reference mechanism, as an example of an index mechanism for a rotating bezel, there is a third prior art technique disclosed in U.S. Pat. This is a rotating bezel that is fitted onto the outside of the watch case body that holds the windshield (the cross sections of the outer surface of the case body and the inner surface of the rotating bezel are hook-shaped and engage with each other to prevent them from falling off). The teeth provided on the lower surface of the bezel engage with the click protrusions provided on the case body in contact with the lower surface, thereby indexing the rotating bezel.

The fact that the guide can be set by grasping and turning the windshield by hand, as in the first conventional example, allows the operation to be performed more directly and quickly than by reusing the windshield, and there is no need to provide an extra operating shaft. Highly preferred. However, since the windshield protruded from the case and was large, it was easy to touch it with hands or other objects, making it easy to change the set time. If an index mechanism is incorporated into the rotating mechanism of the windshield, the resistance against deviation from the set time will be within a predetermined limit due to its quick force, which will not only eliminate this drawback but also improve the operating feel. It is much improved, it is easier to match the set time to the scale, and the reproducibility is also improved.

というように不利益が大きい。 However, there was no suitable index mechanism that could be used for this purpose. For example, in order to use the mechanism of the adduction ring and jump control lever of the second conventional example, the adduction gear must be removably attached to the windshield, and the dial must be raised and the jump control lever must be stored beneath it. . If you do this, (1) the space under the dial will increase, including the storage space for the jump control lever, making the watch thicker, or the pointer shaft will become longer, making it more prone to wobbling. (2) Since the jump control lever must be placed on the top of the movement, the internal diameter of the internal gear that meshes with it cannot be larger than the diameter of the movement.
Since the dial is located within the inner diameter of the inner ring, it is extremely difficult to make the time display surface larger than the diameter of the movement, which makes it extremely difficult to make the time display surface larger than the diameter of the movement. It becomes a constraint. (3) The windshield and the internal rotary gear cannot be integrally molded from plastic, making it impossible to reduce costs. (4) Since the guide mark and the gear are provided separately, the coupling causes errors in mutual angular position, and the guide time corresponding to the indexed state varies depending on the product.
As such, there is a huge disadvantage.

計を構成できない。 Therefore, if you try to apply the third embodiment and fix the windshield to the rotating bezel instead of fixing it to the case body, you can get a rotating windshield with a click, but there is a wall of the case inside the cylindrical part. Therefore, the windshield and the reference shaft cannot be connected well, so an alarm clock cannot be constructed.

ことである。 The present invention overcomes the various difficulties mentioned above,
This is an attempt to realize an index mechanism that is applicable to a structure similar to the first conventional example and has many advantages. That is, the purpose of the present invention is to provide an index mechanism that can be applied to a windshield index clock to improve the index setting accuracy, simplify the structure, ensure freedom in clock design, and improve operability. .

れる。 The circular windshield 8 is larger than the movement 1 and is arranged so as to cover the movement 1. Rough axis 6' from the outer periphery where the circular windshield 8 is indexed
The distance to is larger than the approximate radius of the movement 1 centered on the reference axis 6'. Therefore, an index mechanism with a larger index radius than that provided inside the movement 1 can be provided. If the index radius is large, the index error will have less effect on the angular error of the reference axis 6', and the accuracy of reference setting will improve. If the index radius is large, even if the pitch is the same 10 minutes, the index pitch can be made larger and manufacturing by molding becomes easier. It is desirable to place the index on the outer periphery of the circular windshield 8 as much as possible.

The lower surface of the outer periphery flange 14, which is integral with the transparent part, has moving index teeth 22, and the upper surface of the mounting plate 7 has static index teeth 23 facing each other in a radial circumferential shape. A tooth removal portion 24 is provided on at least a portion of the moving index tooth 22, and a convex portion 25 is provided on the upper surface opposite thereto. The remaining portion of the flange 14 from which the teeth have been removed forms a thin plate spring portion 26. hole 27
is provided to widen the range of springiness. When the circular windshield 8 is assembled into a watch, the convex portion 25 comes into elastic contact with the lower surface of the frame 9 with appropriate pressure. The spring portion 26 is elastically bent and acts as an elasticity imparting member that causes the movable index tooth 22 to press against the static index tooth 23. In this state, when the knurling 12 of the circular windshield 8 is manually rotated forward and backward, the circular windshield 8 rotates and indexes with a click sensation. The connecting body 6 fitted into the notch 13 is also carried around. This configuration may be reversed to provide the dynamic index 22 on the upper surface of the flange 14 and the static index 23 on the lower surface of the frame 9, and make the convex portion 25 provided on the lower surface of the flange 14 come into elastic contact with the upper surface of the mounting plate 7.
