摘要： An aspect of the present invention provides a compact light guide device and a light guide apparatus having high productivity and an even light emission property. A light guide device is made of a translucent material, and LED is disposed in a notch step portion formed by cutting at least a part of an inner peripheral surface, thereby guiding light from LED to emit the light to the outside. Particularly, in a surface and a backside of a sidewall portion of the notch step portion, the sidewall portion facing a light-emitting portion of the light-emitting element, at least an inward surface constitutes a reflecting surface diffusing the light, and a pair of facing surface adjacent to each other on both sides of the sidewall portion constitutes a light acceptance surface receiving the light reflected from the reflecting surface.

摘要： A display device has a light guide plate formed with a display pattern by a plurality of diffusion dots having translucency in a display pattern formed region, a light shielding layer, and a light source. A plurality of the light guide plates are arranged facing each other, and the light shielding layer is sandwiched between the light guide plates. Light from the light source is selectively introduced to one of the light guide plates to display the display pattern of the light guide plate. The light shielding layer has a surface facing an observer's side formed by a low reflectivity material and a surface facing a side opposite to the observer's side formed by a high reflectivity material. A region facing the display pattern of the light guide plate positioned on the side opposite to the observer's side than the light shielding layer is cut out.

摘要： A thickness detecting sensor can widely set a dynamic range for detecting the thickness of a medium, and exactly detect the thickness of the medium even when the dynamic range is widely set in this way. Therefore, the thickness detecting sensor has a fixing electrode and a movable electrode arranged so as to be opposed to each other, a plunger for changing the gap between the electrodes by coming in contact with the medium, and a CR oscillating circuit and an FV converting circuit for converting electrostatic capacity stored between the electrodes into an electric signal for detecting the thickness of the medium. The rear end portion of the plunger comes in contact with the electrode face of the gap side of the movable electrode. The movable electrode is displaced in the direction separated from the fixing electrode correspondingly to the thickness of the medium.
