A through hole penetrating in a vertical direction and a slot which is separated from the through hole in the direction along the sheet surface and is long in a separating direction are provided on a light reflection sheet supported on a support body supporting a light source for reflecting light emitted from the light source, and there are provided a first shaft member fitted in the through hole for setting a position of the light reflection sheet with respect to the support body, and a second shaft member fitted in the slot to enable a relative movement in a longitudinal direction of the slot for setting the position of the light reflection sheet with respect to the support body.

Light reflection sheet, light source device, and display device

It is to provide a reflection sheet, light source device and display device, not only for uniforming the luminance of light emitted from a light source, but also for utilizing a single sheet material to form the reflection sheet having a frame portion that continues to all rims of a flat portion. The reflection sheet is provided with a flat portion that is formed in a substantially square shape, and a frame portion that is folded at a first fold formed on a rim of the flat portion. It is formed in a case shape. It is provided with three second folds divergent from a corner of the flat portion to a rim of a corner on the frame portion, between each corner of the flat portion and the rim of the corner on the frame portion. No gap and step are generated on the corner.

Reflection sheet light source device and display device

Concave marks indicative of an orientation of a circuit board are formed on the circuit board, convex indices to be engaged with the marks are formed in a position in which the circuit is to be attached. An operator confirms the orientation of the circuit board easily and accurately by visually recognizing the marks and touching the marks with a finger. Moreover, the operator positions the circuit board by engaging the marks with the indices.

Light source device, illuminating device, backlight device, liquid crystal display device and display device

A light source device includes a circuit board having a light-emitting element mounted on a one surface; a support body positioned on the other surface side of the circuit board for supporting the circuit board; a rivet having a head portion, which is positioned on a side of the one surface of the circuit board and cannot be inserted into a first through hole provided on the circuit board and the support body, and a shaft portion having a tip side stopped and held on the support body in a penetration via the first through hole; and a reflection sheet arranged on the one surface of the circuit board for reflecting light. The light source device provides a second through hole having a diameter larger or smaller than the diameter of the head portion at the position corresponding to the head portion on the reflection sheet.

Light source device and display device

A light source device includes a circuit board having a LED mounted on a surface, a lens attached to the surface so as to diffuse light emitted from the LED, a reflecting sheet having a through hole in the inside of which the lens is disposed and reflecting light emitted from the LED at an opposite side of the surface, and a restricting member which is disposed at one of an edge of the through hole in the reflecting sheet and the lens, and restricts a deviation of the reflecting sheet in a direction departing from the surface.

Light source device and display device provided with same

There are provided a light source device and a display device which do not generate a wrinkle on an optical sheet even if the optical sheet is held on an LED substrate. A reflection sheet is disposed between each of head portions possessed by a rivet, a positioning rivet and a support rivet and one surface of an LED substrate where an LED is mounted, and a gap in a direction of a sheet thickness is provided between the head portion of each of the rivets and the reflection sheet. In the case in which a sudden thermal change is caused, therefore, the reflection sheet expands or contracts between the head portion of each of the rivets and the reflection sheet so that the wrinkle can be prevented from being generated over the reflection sheet.

A hole that penetrates each light emitting diode board in the thickness direction of the board is provided, on one end portion in the longitudinal direction of each of a plurality of light emitting diode boards which have a plurality of light emitting diodes mounted on one surface, respectively have substantially a strip shape, and are arranged in a plurality of rows. The board holder has: protruding sections which are inserted into the holes of the adjacent light emitting diode boards; and a coupling section which is disposed in the direction orthogonally intersecting the longitudinal direction of the light emitting diode board, has a strip-shape, and couples respective base ends of the protruding sections. The plurality of light emitting diode boards disposed in parallel are held by inserting the protruding sections into the holes.

Board holder, electronic device, and display apparatus

A light source apparatus, an image display apparatus and a television receiving apparatus are provided, which can electrically connect boards with each other even if the boards are separated from each other by more than or less than a predetermined distance. In a light source unit in which plural LEDs are aligned on one surface of a LED board, plural stoppersare arranged at another surfaceof LED boardto stop the stopperat stop slitsof a support memberwhich is to hold the light source unit, and to hold the light source unit to be slidable along one surface of the support member

Light source apparatus, image display apparatus and television receiving apparatus

A light source device which can prevent a stress from being generated on each of circuit boards when connected through a connector and fixed to a support body through a fixture, is provided. There are provided a plurality of circuit boardshaving a light-emitting elementmounted on a one surfaceand disposed apart from each other with a planar direction aligned, a support bodypositioned on the other surface side of the circuit boardsfor supporting the circuit boards, and a connectorfor electrically connecting the adjacent circuit boardsto each other. Inserting holesandfor inserting a fixturefor fixing the circuit boardsto the support bodyare formed on the circuit boardsapart from each other, and a dimension of the inserting holeis smaller than that of the other inserting hole

In a chassis which has a lid plate closing an opening portion of a frame part and in which a plurality of lamps are juxtaposed, the lid plate includes a plurality of plate bodies juxtaposed with their end parts superposed on each other and a connecting unit connects the superposed end parts of the plate bodies and the superposed end parts of the plate bodies, respectively.

Illuminant device

A plurality of clipping portions which clip a plurality of lamps to be juxtaposed are provided on one face, and a mounting portion to be mounted on a supporting member by which the lamps are supported, and holding projecting portions for holding positions of the clipping portions with respect to the supporting member are provided, and two flexible portions which can bend in a direction in which a distance between the supporting sections is changed are provided between at least two clipping portions.

Clip and illuminant device

In a disk loading device, an upper tray is moved by pinions among a loading and unloading position for loading and unloading a disk outside a housing, a storage position for storing the disk inside the housing, and a reproduction position for reproducing the disk at the back of the housing. A lower tray is held by a lock lever onto the upper tray between the loading and unloading position and the storage position. As the upper tray is moved from the storage position to the reproduction position, the lower tray is released from the lock lever by a hold releasing rack provided to the housing. Outside the housing, since the lower tray is held onto the upper tray, the strength of the upper tray is increased. Inside the housing, since the lower tray is released from the upper tray, the upper tray is moved alone. This allows the drive mechanism to drive the upper tray alone, making the configuration of the drive mechanism simple. Therefore, it is possible to simplify the configuration of the drive mechanism without a larger housing.
