Abstract: A switch device of the present invention includes a cylindrical member attached to a through hole of a wristwatch case, an operation member having an operation shaft section inserted into the cylindrical member and an operation head section provided at the outer end of the operation member, a cushioning member attached to the operation head section of the operation member to cover the operation head section, and an exterior member fixed to the operation head section to cover the cushioning member and from which a plurality of portions of the cushioning member project outwardly. Therefore, when the exterior member receives an external impact, the impact can be mitigated by the cushioning member projecting outwardly from the exterior member. As a result, the operation member and the cylindrical member can be prevented from being damaged by the external impact, whereby the impact resistance can be increased.

Abstract: A switch device of the present invention includes a cylindrical member fitted into a through hole of a wristwatch case, an operating member having an operation shaft section to be inserted into the cylindrical member and an operation head section, and a lock member fixed inside the operation head section. The cylindrical member includes engaging projections, and the lock member includes resilient support sections which have a space with respect to the inner circumferential surface of the operation head section and are resiliently deformed in a radial direction, and lock sections with which the engaging projections are resiliently engaged. Accordingly, when the operating member is pushed inward and rotated, the engaging projections resiliently deform the resilient support sections and are engaged with the lock sections. Also, only by the operating member being rotated against the regulating force of the lock section, the lock sections are disengaged from the engaging projections.

Abstract: A portable image pickup apparatus comprising a camera in the apparatus proper. The apparatus comprises an attachment fittable over the apparatus proper and having a part that aligns with at least an image pickup lens 6 of the camera unit. The part has a special image pickup function unit (telescopic lens) to give a special image pickup effect to an image picked up by the camera unit.

Abstract: An electronic apparatus is provided which enables miniaturization and has not only good electromagnetic shielding characteristics but also good resistance to impact. The electronic apparatus includes: an instrument case having an upper case and a case back, an electromagnetic shielding body which is contained in the instrument case, and electronic members, for example, an analog board, a digital board and the like, which are disposed in the shielding body. The body comprises a pair of half body members of shielding material. One of the pair is a first shielding member having a standing and surrounding periphery and an opening at an end. The other of the pair is a second shielding member having a standing and surrounding periphery and an opening at an end. The openings and of the first and second shielding members are opposed to each other so that they can be coupled with each other by fitting one of the standing and surrounding peripheries into the other thereof.

Abstract: A translucent or transparent panel member which has a protrusion on the upper surface thereof is disposed on the upper surface of a plate-like luminescent member, to form a luminescent device. The luminescent device is manufactured by forming a protrusion on the upper surface of the panel member, providing a masking layer on the peripheral side surface and the upper surface, of the protrusion, forming a printed layer on the upper surface of the panel member, forming a printed layer on the upper surface of the protrusion after removing the masking layer from the protrusions, and arranging the panel member on the upper surface of the plate-like luminescent member. Such a plate-like luminescent device is arranged in the timepiece case to illuminate the analog hand mechanism. Such a plate-like luminescent device is also arranged in an electronic apparatus case to illuminate a liquid crystal display device of the electronic apparatus.
