Abstract: The present invention aims to achieve a high display quality and cost saving while providing a dual function as a capacitive touch panel. A liquid crystal display unit 1 has a liquid crystal display cell 10; and a compensation cell 20, disposed opposite the liquid crystal display cell 11 to improve an optical characteristic of the liquid crystal display cell 10. The compensation cell has a transparent plate 21/22, and a transparent electrode group 28 for a capacitive touch panel. The transparent electrode group 28 is formed at the transparent plate 21/22 to allow the compensation cell 20 to function also as the touch panel.

Abstract: The invention relates to a computer mouse which is one kind of coordinate input devices for a computer, and more particularly to a computer mouse which is suitably used for a portable computer. The mouse has: a thin mouse case in which an upper face portion opposing a palm when the mouse is used is formed into a downward-concaved shape; and a plate-like member having a shape which extends along the downward-concaved upper face of the mouse case, and the plate-like member is attachable to the downward-concaved upper face of the mouse case in both an upward-convex direction and a downward-concave direction.

Abstract: Attachments are respectively attached to one ends of a pair of light guides, which are integrally formed via a connecting portion, such that the attachments surround the one ends of the light guides. The one ends protrude from a rear face of a receptacle body and are opposed to a light-emitting device and a light-receiving device, respectively. The attachments are inserted and positioned in guide holes formed respectively on the light-emitting device and the light-receiving device, and the optical axes of the pair of light guides and the optical axes of the light-emitting device and the light-receiving device are aligned with each other.

Abstract: A touch panel input device of the invention has a panel, an X-line electrode (first electrodes) arranged on a front surface side of the panel, a Y-line electrode (second electrodes) disposed on the back surface side and shifted in planar position relative to the X-line electrode. The device detects whether or not a finger has touched the vicinity of a zone between the X-line electrode 20 and the Y-line electrode on the front surface of the panel. An electrostatic capacitance of the X-line electrode and an electrostatic capacitance of the Y-line electrode are made equal by way of increasing the area of the Y-line electrode with respect to that of the X-line electrode or by way of selecting an appropriate material and/or thickness of the panel and/or the coat.

Abstract: An EL-illuminated switch which restrains the deterioration of an EL element resulting from outside pressure without causing unevenness of illumination, including an EL sheet, a rubber sheet, a dome switch, and a substrate. In the EL sheet, a luminescent part is formed at a position directly under a key top. The size of the luminescent part is smaller than the key top. A transparent electrode is disposed on the front surface side of the luminescent part, and a back surface electrode is disposed on the rear surface side. The transparent electrode is larger than the luminescent part. The back surface electrode includes an electrode principal part that is in contact with the back surface of the luminescent part and isolated from the lower sheet.
