Problems solved by technology

[0004] However, in such a watch switch device, since the cylindrical member is held by the elastic member provided between the inner peripheral surface of the through hole of the watch case and the outer peripheral surface of the cylindrical member, the cylindrical member is easy to move. Displacement in its radial direction makes it unstable, so the strength of the cylindrical member cannot be ensured unless the outer diameter of the cylindrical member is formed larger
Therefore, not only the outer diameter of the cylindrical member becomes larger, but also the inner diameter of the through hole of the watch case becomes larger, and the thickness of the watch case becomes thicker.

Embodiment Construction

[0015] Below, refer to Figure 1 to Figure 6 , and an embodiment in which the invention is applied to a wristwatch will be described.

[0016] Such as Figure 1 ~ Figure 3A , Figure 3B As shown, the watch has a watch case 1 . The watch case 1 is composed of a first case 2 and a second case 3 . The first case 2 and the second case 3 are formed of a lightweight and highly rigid metal such as titanium (Ti).

[0017] In this case, if figure 2 as well as Figure 3A , Figure 3B As shown, the second case 3 is attached to the upper portion of the first case 2 via a waterproof ring 3 a, and has a structure in which its outer periphery protrudes slightly from the outer periphery of the first case 2 to the outside. A timepiece glass 4 is attached to the upper opening of the watch case 1 , that is, the upper opening of the second case 3 via a gasket 4 a. Further, a back cover 5 is attached to the lower portion of the watch case 1 , that is, the lower portion of the first case 2...

Abstract

The invention provides a switch device including a case which is provided with a through hole and has a built-in module, a cylindrical member which is attached to the through hole of the case and whose inner end portion protrudes inside the case and is held in the module and outer end portion protrudes outside the case, and an operation member including a shaft section which is arranged inside the cylindrical member in a manner to be slidable in an axial direction of the cylindrical member so as to operate the module and a head section which is provided on an outer end portion of the shaft section and covers and slidably holds the outer end portion of the cylindrical member.

Description

technical field [0001] The present invention relates to a switch device used in electronic equipment such as a wristwatch, a mobile phone, and a mobile information terminal, and a timepiece including the switch device. Background technique [0002] For example, in a watch switch device, a structure is known. As described in Japanese Patent Application Laid-Open No. 2010-249716, when a cylindrical member is installed in a through hole of a watch case with a built-in clock module, the watch case An elastic member is provided between the inner peripheral surface of the through hole of the body and the outer peripheral surface of the cylindrical member, and an operating member for operating the timepiece module is provided inside the cylindrical member in this state. [0003] In this switch device, when the watch case receives an impact from the outside and a positional displacement occurs between the watch case and the clock module, the inner peripheral surface of the through h...
