| 20080198625 | LIGHT GUIDE SHEET AND MOVABLE CONTACT UNIT AND SWITCH USING THE SAME - The disclosed relates to a light-guide-sheet used in operation panel of a various electronic equipment, and a movable-contact-unit and a switch using the same, which have a simplified structure free from uneven illumination and a cheap cost price. Therefore, the light-guide-sheet is provided with the light-guide-member including an inlet, a generally strip-shaped guide-path coupled with the inlet, and generally circularly and irregularly shaped light-emitters coupled with the guide-path, each formed from a polymer having an index of refraction different from that of base-film and formed in grooves provided on a base-film. | 08-21-2008 |
| 20080302642 | MOVABLE CONTACT ELEMENT AND SWITCH USING THE SAME - A movable contact point made of a thin conductive metal sheet in an approximate dome shape is attached to the lower surface of a transparent base sheet, and the base sheet is provided at the upper or the lower surface with a fluorescent layer in the location above the movable contact point. Since, in the make-up, light can be made available for illumination in many colors other than that generated from a light emitting device, a movable contact element, as well as a switch formed using the contact element, that offers various illuminating modes can be implemented in a simple structure. | 12-11-2008 |
| 20080314722 | MOVABLE CONTACT ASSEMBLY AND SWITCH USING THE SAME - A movable contact assembly includes a movable contact having a dome shape, a base sheet contacting an upper surface of the movable contact, a columnar portion provided on an upper surface of the base sheet, and a light guide sheet provided on an upper surface of the columnar portion. The light guide sheet has a light-receiving surface for introducing light into the light guide sheet, and allows the introduced light to be emitted from an upper surface of the light guide sheet. The base sheet includes a dome portion having a concave lower surface, and a flat portion connected with an outer edge of the dome portion. The columnar portion is positioned on the upper surface of the dome portion away from the outer edge of the dome portion of the base sheet. This movable contact assembly provides a switch illuminating its upper surface and being activated easily with a preferable feeling. | 12-25-2008 |
| 20100007973 | LENS ACTUATOR, LENS UNIT USING THE LENS ACTUATOR AND METHOD FOR MANUFACTURING THE LENS UNIT - A lens actuator has a carrier, a cover, a first spring, a second spring, a coil, and a magnet. The carrier with a cylindrical shape is provided with a hollow section formed along a first direction, and has a holding section formed on one side of the first direction. The hollow section has a shape configured to mount a lens barrel therein. The cover, which is disposed on the side having the holding section of the carrier, has a supporting section that meets with the holding section of the carrier. The first spring and the second spring make a resilient contact with each of both surfaces in the first direction of the carrier. The coil is circumferentially disposed on the carrier so as to face the magnet. Of the coil and the magnet, one is mounted on the carrier and the other is disposed on the outer or the inner periphery of the carrier. | 01-14-2010 |
