Abstract

(57) [Abstract] [Purpose] In the rotating bezel rotary switch mechanism of a portable watch, the mode of the watch can be changed without contact, preventing malfunctions due to external influences or abrasion, and enabling switching of many different modes. Make it. [Configuration] By rotating the rotating bezel 2, the drive wheel 3,
4 is rotated, and the drive wheel transmits the rotation to the inner rotary ring 5.
A sensor 11 reads the position of an identification pattern 6 attached to the underside of the adduction ring, and a module 7 determines the mode.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a rotating bezel rotary switch mechanism in a portable watch.

0002

[Conventional technology]

The conventional rotating bezel rotary switch mechanism has a rotating bezel as shown in Figure 2. 2. A cam-shaped slope 12 is attached to the bottom surface of the case 1. The transmitted transmission pin 8 presses the switch spring 9, and its vertical movement causes the module 7 to move. The mode was changed by turning the switch on and off. Many modes available When crossing, multiple transmission pins were combined and installed in the case.

0003

[Problem that the idea aims to solve]

However, according to the conventional rotating bezel rotary switch structure, the bottom of the rotating bezel 2 The mode was switched by moving the transmission pin 8 up and down. Multiple modes can be switched ON/OFF by combining the transmission pins 8. In order to switch between several modes, it was necessary to use multiple transmission pins. In addition, since the switch spring 9 is used, it becomes a contact point, so it is protected against external shocks and The transmission pin 8 may no longer operate due to scratches on the transmission pin or rotating bezel cam, and the motor may There was a problem that it became impossible to switch modes.

0004

[Means to solve the problem]

In order to solve the above problem, in this invention, the gear of the rotating bezel rotates the drive wheel. , the drive wheel is an identification system that rotates the adductor ring on the module and fixes it behind the adductor ring. Move the pattern. A sensor on the module reads the identification pattern and It is now possible to switch between multiple modes.

[0005]

[Effect]

With the above structure, instead of turning ON and OFF with a transmission pin, the internal rotation ring Since the identification pattern on the back is read by a sensor, the number of modes can be increased by devising the identification pattern. It becomes possible to make many types of. In addition, since it is non-contact, the exterior structure is complicated. It also improves durability.

【Example】

Embodiments of the present invention will be described below based on the drawings. In Figure 1, 1 is the case , 2 is a rotating bezel with gears formed on the bottom surface, and 3 is a drive with waterproof packing. Car A, 4 is a driving car B, 5 is an adductor ring with an identification pattern 6 fixed on the lower surface, Drive wheel A3 can be rotated from the outside diameter and drive wheel B4 can be rotated from the inside diameter through the hole provided in case 1. An inner ring 5 is rotatably fixed to the inner diameter of the case, and a rotating bezel 2 is attached to the top surface of case 1.

[0007] Next, the operation will be explained. Rotating the rotating bezel 2 drives the gear on the bottom of the rotating bezel. Rotate car A3. Then, the drive wheel B4 fixed to the drive wheel A3 also rotates. In conjunction with this, the inner rotary ring 5 rotates. It is fixed to the adduction ring 5 from the back side. The identification pattern 6 also rotates at the same time, and the sensor 11 detects the position of the rotated identification pattern. Upon optical reading, module 7 determines the mode. Identification pattern 6 is a circuit pattern. It may consist of a turn or an identification sheet.

[0008] FIG. 3 is a plan view showing an example of an identification sheet constituting the identification pattern 6 of this embodiment. be. The color of the identification sheet is printed in three colors: red (circle mark), blue (triangle mark), and yellow (square mark). The sensor 11 optically reads the combination, and the module 7 switches the mode. Ru. In this way, the module mode can be switched depending on the color combination of the identification sheet. Many types are possible.

[0009]

[Effect of the idea]

As explained above, this invention rotates the drive wheel by rotating the rotating bezel. , the drive wheel transmits rotation to the adduction ring. Identification pattern fixed to the underside of the adduction ring The sensor reads the position of the switch and the module containing the sensor switches off the mode. By switching, there will be no wear on the bezel and it will be possible to switch between many modes. There is an effect.
