DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an analog wristwatch with an alarm.

[Conventional technology]

FIG. 2 shows a well-known example of a conventional analog wristwatch with an alarm. 1 is a first external operating member that can be operated in the axial direction and rotational direction; 2 is a second external operating member that is also operable in the axial direction and rotational direction; 3 is a date wheel with a date printed on it; 4 5 represents a day wheel on which day letters are printed, and 5 represents an inner rotation ring on which a mark 5a is printed. The operation of the first external operating member 1 is the same as that of a regular watch; from the portable state, pull it out one step and rotate it to adjust the day and day of the week, and pull it out two steps and rotate it to adjust the time. do. The second external operating member has three states of axial movement: 0th stage, 1st stage, and 2nd stage.
The stage is the state in which the alarm is being carried, the 0th stage is the state in which the alarm is stopped, the first stage is in the alarm set state (the state in which the alarm is canceled), and the rotation of the second stage causes the inner rotary ring 5 to rotate. , the alarm time indicated by the mark 5a can be corrected. In addition, as another example, as disclosed in Japanese Patent Application Laid-Open No. 51-46924, there is one in which the timepiece movement is made largely eccentric from the center of the timepiece body, and the remaining space is made up of a sound alarm device and a circuit block. In this embodiment, it is assumed that the external operating member on the 9 o'clock side performs all operations related to instructions, and the external operating member on the 3 o'clock side performs operations related to volume and electric switches such as switches.

[Problem that the invention seeks to solve]

However, in the case of the former structure, one external operating member is located on the 2 o'clock side facing the center of the watch, and for shapes other than round, it is difficult to process the case abutment due to the structure and design. Because an adduction ring is used for instructions, designs are limited to round shapes only, and it is difficult to accommodate square and oval models, making it difficult to design dress-like models that are currently in high demand. The problem of not being able to do it, and 2.
Since the two external operating members are close to each other, there is a problem in that the respective switching members that engage with the external operating members overlap each other, resulting in a complicated shape.

In addition, in the case of the latter example, the pointer would be offset from the center of the watch body, making it impossible to create a standard design.
It becomes a watch with a special image. As for operation, all pointer adjustments are made using the external operating member on the 6 o'clock side, so if an alarm hand is assumed, adjusting the alarm time and correcting the current time will be performed using the same external operating member, and the alarm time will be adjusted using the same external operating member. There is also the problem of accidentally correcting the current time when you want to correct it.

The present invention is intended to solve these problems, and its purpose is to effectively utilize movement space, provide easy-to-understand operation, and enable a wide range of designs from functional clock-like designs to dress-like designs. Our goal is to provide an analog wristwatch with an alarm that makes this possible.

[Means for solving problems]

The analog wristwatch with alarm of the present invention includes a first external operating member for correcting the current time and a second external operating member for correcting the alarm time.
One is located at the 3 o'clock side and the other at the 9 o'clock side, and the rotation centers of the hand that displays the current time and the hand that displays the alarm time are on the same axis and are located approximately in the center of the watch body. The two external operating members are engaged with respective dedicated positioning members that determine the axial position.

[Effect]

According to the above structure of the present invention, the two external operating members are placed at the 3 o'clock and 9 o'clock sides, which are less likely to be affected by the external shape of the model, and the hands are placed approximately in the center of the watch body. It can be adapted to various designs, and the space for the switching section can be separated on both sides, so space can be used effectively.

〔Effect of the invention〕

As described above, according to the present invention, the basic watch winding stem and the alarm winding stem are arranged at the 3 o'clock side and the 9 o'clock side, so that even a round model like 78 in FIG.
Both the No. 6 corner model and the No. 75 oval model have the effect of being able to process the winding stem in the same way and being able to handle a wide variety of designs. In addition, each switching portion that engages with the winding stem does not overlap on a plane and is operated simply by means of actual screws and bolts, which also has the effect that the parts can be made into simple shapes. Furthermore, in the case of the embodiment of the present invention, the switching part for the alarm is arranged on the dial side of the movement, and the switching part for the basic timepiece is arranged on the back cover side of the movement,
The circuit section is arranged in the former, and the calendar correction related parts are arranged in the latter. Since the alarm wheel is located on the dial side of the movement, the alarm switching parts, display lever, alarm small iron wheel,
The alarm-related parts including the alarm intermediate wheel, the alarm wheel jumper, etc. are located at approximately the same height, and the parts have the advantage of being easy to engage and mesh with each other. In addition, the circuit section consisting of an IC chip and buzzer transistor, which takes up relatively little space in the thickness direction, is placed on the back cover side of the movement, so the alarm switching section is placed with sufficient space in the thickness direction. There is an effect that it can be done.

In the case of a structure in which the gear wheel is operated by a bolt and driven by engagement with a small iron wheel, it is better to place the small iron wheel and bolt on the same side with respect to the winding stem to avoid tilting due to play between the wheel and the winding stem. It is well known that it is possible to reduce variations in the amount of engagement that occur in the process and ensure stable engagement. In the case of this example, the switching part for the basic watch is placed on the back cover side of the movement,
By stacking the basic clock wheel on a plane with the alarm wheel, the basic clock wheel that meshes with the small iron wheel can be brought to the center, and the inner diameter of the date wheel, which is adjusted in conjunction with the wheel, can be adjusted. It has the effect of being able to be made small and organized into a compact calendar model.

As described above, the present invention provides an analog wristwatch with an alarm that is compatible with a general dress-like design and is easy to operate, despite having an additional alarm function.

In this embodiment, the alarm stem, which is frequently used, is placed on the 3 o'clock side where it can be easily handled, but it may be placed on the 3 o'clock side without any problem, as long as ease of use is sacrificed a little.
