The present invention relates to a timepiece and an electronic apparatus, which comprise a casing, a digital face and a time counting module, both being provided in the casing. A bulb-shaped solar battery element is mounted on the digital face. The bulb-shaped solar battery element is allowed to receive the external light sufficiently to generate the electric power efficiently.

Timepiece and electronic apparatus with bulb-shaped semiconductor element

With a dial for a timepiece comprising a decoration member having a plurality of through holes formed vertically on a luminescent member , the cross-sectional area of lower-side holes of the decoration member is formed to be larger than that of upper-side holes . Therefore, even if a substrate is thick, the diameter of the upper-side holes of the through holes can be formed to be small sufficiently. Moreover, compared to a dial size for a timepiece wherein the decoration member is placed on the luminescent member , the diameter of the through holes of the decoration member is small. Thus, it is possible to take in enough light from the luminescent member through the lower-side holes to ensure the sufficient amount of light through the through holes . It is possible to obtain sufficient illuminance for the dial.

Dial for timepiece, manufacturing method thereof and timepiece

A dial for timepiece is provided which includes a decoration member having a through hole, and a luminescent member disposed under the decoration member. A first surface processed layer is provided on an upper surface of the decoration member, and a second surface processed layer having a light-transmissive property is provided on an upper surface of the luminescent member. When the luminescent member is turned on, light emitted from the luminescent member is transmitted through the second surface processed layer and passes through the through hole of the decoration member. Because the transmitted light illuminates the upper surface side of the decoration member partially in accordance with the through hole, the dial is visible even in a dark place. In addition, decoration effects can be achieved by both the first surface processed layer and the second surface processed layer in accordance with the through hole.

Luminous Dial for timepiece

A tilt detecting device for use in various electronic apparatuses such as a watch, electronic notebook or the like. The tilt detecting device includes a projection in a part of a ball containing portion formed in an interior of an insulation case. In the insulation case, two conductive pins are disposed thereon in parallel with each other with a predetermined space, which have a large diameter portion, a small diameter portion and a step between them. In the ball containing portion, a conductive ball is contained therein, which is movable along in a longitudinal direction of the two conductive pins in the ball containing portion when the insulation case is inclined. Only when the insulation case is inclined, the conductive ball is at a position on the large diameter portions to be electrically in contact with the two conductive pins to output a corresponding detection signal.

Tilt detecting device

An analog hand mechanism having hands in a watch case, and a plate-like luminescent device in the watch case, to illuminate the analog hand mechanism. A metallic layer or a metallic ink layer, for giving a feeling of metallic gloss by receiving illumination of light emitted from the surface of the luminescent device, is disposed on at least a side of the upper surface and the lower surface of the luminescent device.

Luminescent device and watch with luminescent device

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. An electromagnetic shielding partition member is disposed between a part, e.g., the analog board, of the electronic members and the other part, e.g., the digital board thereof. Outside one of the half body members, an antenna is provided.

Wrist instrument and electronic apparatus

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.

Luminescent device, timepiece, electronic apparatus and method for manufacturing luminescent device

The present invention relates to a display device which is used for various types of electronic apparatuses, e.g., an electronic watch, an electronic pocket notebook, and the like, and an electronic device. In the device or apparatus, a solar battery member having a lot of light passing openings for passing light is provided between a liquid crystal display member and a plate-like light emitting member disposed at a position lower than that of the liquid crystal display member.

A thin antenna 20 having a satisfactory length, its making method, and an electronic device such as a wristwatch having such antenna. The antenna 20 is formed on a lower surface of a transparent plate 5 by printing an ornamental layer 22 on a lower surface of the transparent plate 5, forming a conductive ink layer 23 on the ornamental layer 22, and further forming plated metal layers 24, 25 on the conductive ink layer 23. Since the antenna 20 is thin as a whole, it may be provided within a small electronic device such as a wristwatch.

Antennas and their making methods and electronic devices or timepieces

A resin band is formed by molding a first resin member by injection molding to cover a net member excluding its periphery, and by molding a second resin member by injection molding to cover a periphery of the net member exposed from the first resin member. In the resin band formed in this manner, the adhesion strength of the first and second resin members is increased by the net member, and the resin band can be colored in two colors by changing the colors of the first and second resin members.

Resin wristwatch band having first and second molded resin members

An electronic wrist watch having a sound producing unit and an electrooptic data display unit, has a single flat plate member a lower surface of which is contacted with a user's hand, and a case member which is attached to one end of the plate member so as to be freely opened and closed over the plate member. A switch input section for data input is mounted on an upper surface of the plate member. An analog display unit for displaying time with hands, and a sound emitting section are mounted on the upper surface of the case member so as not to overlap each other. An electrooptic data display unit for displaying data is mounted on the lower surface of the case member. A sound producing unit and an electronic circuit for driving the analog display unit and the sound producing unit are housed in the case member. The sound producing unit is located under the sound emitting section in the case member, and the electronic circuit is electrically connected to the switch input section so as to cause the electrooptic data display unit to display data from the switch input section.
