A connecting structure includes a connecting pin, a pin catch, a biasing member, and a holder. The connecting pin has a first portion, a second portion thicker than the first portion, and a step therebetween and connects a connecting object and a connected object (objects) by being inserted into their insertion holes. The pin catch moves in a recess in one of the objects in moving directions that are not an extending direction of the insertion holes and has a pin engagement portion that engages the step. The biasing member biases the pin catch in one of the moving directions. The holder is on the one of the objects and transitions, in response to user operation, to a first state where the holder and the biasing member holds the pin catch or a second state where the pin catch is detachable from the recess.

Connecting structure and wearable device

A case includes a main case body and an exterior member. The exterior member is welded to the main case body with laser light. The laser light is irradiated onto an irradiation surface. A welding part of the main case body and the exterior member is formed on the inner periphery surface extending along a height direction of the case and is formed such that the irradiation surface is perpendicular to the incident laser light.

Case and timepiece

A case includes a main case body and an exterior member. The exterior member is welded to the main case body with laser light. The laser light is irradiated onto a welding part of the main case body and the exterior member and reflected at an irradiation surface, and a reflected-light receiving part is formed at a position where the reflected laser light is irradiated according to an incidence angle of the laser light to the irradiation surface. The exterior member includes a flange part which is disposed on an upper side of the main case body and which protrudes toward an inner side of the main case body. A lower surface of the flange part includes a module receiving surface which receives a module to be disposed inside the main case body, and the reflected-light receiving part is formed at a part of the module receiving surface.

A connection structure includes: a connection pin that includes a first part and a second part between which a step is formed and that connects a first target and a second target by being inserted in an insertion hole; and a pin locker movable in a moving direction in a recess formed in either the first or second target. The pin locker has a pin engaging part that engages with the step of the connection pin and a pin insertion part. One of the recess and the pin locker has a first abutting part, and another has a first abutted part. When the pin locker is at a specific position and the first abutting part abuts the first abutted part, at least either an orientation or a position of the pin insertion part is limited such that the second part is allowed to pass through the pin insertion part.

Connection structure and wearable device

A watch case having a through-hole, an operating member including an operating shaft to be inserted to the through-hole of the watch case, an exterior member mounted on the operating member and configured to be displaced in a shaft direction of the operating shaft and be rotated together with the operating member, and a buffer member located between the operating member and the exterior member are provided. Therefore, when the exterior member receives impact from outside, the impact can be buffered by the buffer member. As a result, the operating member can be prevented from being damaged because the impact from the outside is not directly transmitted to the operating member, thereby improving impact resistance.

Switch device and timepiece

A wristwatch including a case including a band attachment section having an attachment hole, a band including a coupling hole in one end portion located coaxially with the attachment hole of the band attachment section, a coupling member inserted into the coupling hole of the band and the attachment hole of the band attachment section and coupling the band with the band attachment section, and a fixing member fixing the coupling member to the attachment hole of the band attachment section or the coupling hole of the band.

Wristwatch

A timepiece provided with a metal case having a fitting section which is annularly provided in a lower portion of the inner circumferential surface, a metal lid body having a lid main body section which is arranged on a lower end of the case and covers a lower portion of the case and a cylindrical section which is arranged in the fitting section of the case, and a synthetic resin gasket having a gasket main body section which is arranged between the fitting section of the case and the cylindrical section of the lid body and a spacer section which forms a space between a lower end surface of the case and an upper surface of the lid main body section.

Timepiece

A sensitivity adjustment device adjusts radio wave sensitivity of an antenna which wirelessly transmits/receives a signal to/from an external device. The sensitivity adjustment device includes a case and a ring-shaped rotating member. The case houses the antenna. The rotating member is disposed on the outside of the case in such a way as to be rotatable. The rotating member includes (a) a shielding part which shields a radio wave and (b) a penetration part which allows penetration of a radio wave. A positional relationship between (a) the antenna and (b) the shielding part and the penetration part is changed by rotation of the rotating member so that the radio wave sensitivity of the antenna is adjusted.

Sensitivity adjustment device, radio wave communication device and watch

A dial plate unit includes a dial plate provided with an outside dial plate element having an opening, an inside dial plate element spaced at a predetermined distance from the outside dial plate element, and a frame member provided in the opening of the outside dial plate element and closing a gap between the periphery of the opening and a part of the inside dial plate element corresponding to the periphery of the opening. The unit further includes one indicating member disposed in a side of the outside dial plate element opposite to the inside dial plate element and being movable along the outside dial plate element, and one auxiliary indicating member disposed in the opening and being movable between the outside and inside dial plate elements. A device using the dial plate unit includes a indicating member operating module which operates the indicating member and auxiliary indicating member.

Dial plate unit with indicating members and dial plate, and device with the dial plate unit

A wrist mountable electronic device case such as a wrist watch case includes: a main body of a synthetic resin, in and on which a housing portion and a pair of band attaching portions are formed, one attaching portion being formed with an antenna containing area; a metallic sheath member mounted on a top surface of the body, having an opening corresponding to a top opening of the housing portion, and not covering the containing area; a light transmitting member mounted on the opening of the sheath member; a metallic back cover covering a bottom opening of the housing portion; and a fixing unit fixing the sheath member and the back cover with each other while sandwiching the main body therebetween. A watch module is housed in the housing portion, an antenna is contained in the containing area, and a lead connects the antenna to the watch module.
