A display device includes a display panel, at least one light source, a diffusion plate, an optical member, and a plurality of adhesive layers. The diffusion plate diffuses light from the at least one light source. The optical member is disposed between the diffusion plate and the at least one light source and has at least one transmitting portion that transmits the light from the at least one light source and a reflective portion that reflects the light from the at least one light source. The adhesive layers bond the optical member and the diffusion plate with an air layer therebetween. The adhesive layers are arranged spaced apart from each other in a direction in which the optical member extends. The air layer has the same thickness as the adhesive layers and is located between an adjacent pair of the adhesive layers.

Display device and surface light source

A lighting device includes a plurality of light sources, a light diffusion plate, a sheet-like optical member, and a partition. The light diffusion plate is arranged opposite the light sources. The light diffusion plate diffuses light from the light sources. The optical member is disposed between the light diffusion plate and the light sources. The optical member includes a transmitting part that transmits the light emitted from the light sources and a reflecting part that reflects the light emitted from the light sources. The partition is arranged between adjacent light sources. The optical member is held by a support portion that is integrally provided to the partition and protrudes from an end portion of the partition toward the light diffusion plate.

A display device of which an entire thickness in front and rear directions can be reduced and in which temperature of a lower portion can be prevented from being high is provided. A television device (display device) () includes a light source part (), an optical sheet (), and a rear frame (). The light source part () is disposed in the upper portion of the television device (television device) () and a hollow light-guiding region () is provided between the reflection sheet () and the optical sheet (). In the reflection sheet (), a distance to the optical sheet () is less in the lower portion than in the upper portion.

Display device

A projector includes a light source portion; and an optical scanning portion that scans light from the light source portion, wherein the light source portion comprises a first holder that holds a light source, and a second holder that holds an optical portion through which light from the light source is emitted, and the first holder and the second holder are arranged in that order from a light emitting direction.

Projector having holders arranged in a light emitting direction

A projector for projecting an image includes a light source that outputs light; a reflecting member that reflects the light from the light source; and a diaphragm member with an aperture that restricts a range of flux of either an incident light incident to the reflecting member or a reflected light reflected by the reflecting member. The aperture may penetrate through the diaphragm member along a direction of thickness of the diaphragm member. The diaphragm member may be arranged so as to not block the other of the incident light or the reflected light, and a direction perpendicular to the direction of thickness may be oblique with respect to an optical path of either the incident light or the reflected light.

An optical disc device comprises a disc clamper. The disc clamper is provided with: a first member provided with a first circular disc, and with a plurality of upstanding pieces formed with predetermined spaces therebetween along a circle concentric to the first circular disc, the upstanding pieces having an engaging claw at the distal end thereof; and a second member provided with a second circular disc in which are formed a plurality of through-holes into which the plurality of upstanding pieces are inserted, and with a plurality of peripheral walls formed with predetermined spaces therebetween along a circle concentric to the second circular disc. Rotation in a state where the upstanding pieces have been inserted into the through-holes through the spaces between the peripheral walls causes the engaging claws to engage the peripheral walls.

Optical disc device

A drive device for an optical disc apparatus, comprising: a traverse chassis; a vertically moving lever arm for covering part of the lower surface of the traverse chassis and supporting the traverse chassis; a first circuit board disposed on the upper surface of the traverse chassis; a second circuit board disposed on the lower surface of the traverse chassis; and a flexible cable that passes between the traverse chassis and the lever arm, is connected by one end thereof to the first circuit board, and is connected by the other end thereof to the second circuit board; wherein an opening that has a greater width than the width of the flexible cable is provided to a section of the lever arm in contact with the flexible cable.

Drive device for optical disc apparatus

A drive device for an optical disc apparatus, wherein the tooth comprises a tooth body fixed to an optical pickup; support pieces projecting from the tooth body toward a lead screw; resin spring pieces extending from the support pieces in a direction orthogonal to the axial direction of the lead screw; a plate part formed in a direction parallel to the axial direction of the lead screw from the resin spring pieces; meshing cogs formed on the plate part on the side near the lead screw; a cover projecting above the lead screw from the plate part disposed above the meshing cogs, straddling the lead screw, and bending sharply downward at the distal end; and a handle projecting from the tooth body.

A drive device for an optical disc apparatus, wherein the tooth comprises a tooth body fixed to an optical pickup, two support pieces projecting from the tooth body toward a lead screw, two resin spring pieces provided with a base part on the projecting end of each of the support pieces and extending in a direction orthogonal to the axial direction of the lead screw, a plate part having a base part on the extending ends of the resin spring pieces and formed in a direction parallel to the axial direction of the lead screw, meshing cogs formed on the plate part on the side near the lead screw, and a linking part formed across the space between the resin spring pieces.

In an optical disc apparatus, a harsh blow sound due to collision of first stoppers of a tray and third stoppers of a main chassis when the tray reaches to a terminal position of drawing thereof is reduced. When a second stopper of the tray contacts with the front end portion of a cam slider, the front end portion of the cam slider is elastically deformed so that moving speed of the tray is largely decelerated. Consequently, the blow sound due to contact of the first stoppers of the tray and the third stoppers of the main chassis is radically reduced.
