PROBLEM TO BE SOLVED: To provide a means of preventing electronic equipment with a slot for a card type device from illegally being used by a suspicious person by extracting the card or inserting an illegal card while the electronic equipment is displayed. SOLUTION: The electronic equipment is equipped with a means of stopping a lock plate 3 from moving at a position where at least a portion of the insertion hole of the slot 1 for the card type device is covered. The lock plate 3 formed integrally with a knob 4 for operation is screwed with a screw 7 penetrating a through hole 5 arranged on the equipment housing or the lock plate 3 is locked to the equipment housing by a lock device to stop the lock plate 3 from moving, thereby preventing a card which is inserted into the equipment through the insertion opening of the slot 1 for the card type device from being extracted and stolen and the equipment from being damaged owing to use of an illegal card.

PROBLEM TO BE SOLVED: To provide a display device that is configured not to be full of heat even when installed horizontally on a mounting surface, can be supported in a stable state even when installed at a small angle relative to the mounting surface, and has superior operability.SOLUTION: There is provided a display device that includes a housing having an upper surface where a display screen is provided and a bottom surface positioned on a mounting surface side, the bottom surface having: an inclined surface which has one side end part inclined to the upper surface side; a first tilt leg which is provided to be stored at a side end part opposed to the inclined surface and a projection part projecting from the bottom surface in a stored state; and a second tilt leg which is provided to be stored on the inclined surface. When the housing is supported obliquely relative to the mounting surface, the first tilt leg is projected so as to support the housing by the projected first tile leg and the inclined surface. When the housing is supported horizontally on the mounting surface, the second tilt leg is projected so as to support the housing by the projected second tile leg and the projection part of the first tilt part.

PROBLEM TO BE SOLVED: To provide a reflection sheet capable of being formed with a single sheet material, capable of enhancing reflection efficiency and uniformalizing brightness of light emitted by a light source, and having a frame part joining the entire circumference of a flat part, and a light source device as well as a display device. SOLUTION: The reflection sheet has a flat part 51 having a substantially square shape and a frame part 52 to be folded at a first folded line 5b formed in the circumference of the flat part 51, and has a case shape. In the reflection sheet, between each corner part 51a of the flat part 51 and the periphery of a corner part 52a of the frame part 52, three second folded lines 53a, 53b, 53b spaced gradually wider from the corner part 51a of the flat part 51 to the periphery of the corner part 52a of the frame part 52 are provided, so that a gap and a step do not occur at the corner part 52a.

PROBLEM TO BE SOLVED: To provide a light reflecting sheet which expands and contracts by thermal expansion, the light reflecting sheet being configured to be prevented from being positionally displaced in the direction of the surface thereof and in the direction of the circumference thereof to thereby enable the position of the light reflecting sheet to be held at an appropriate position, a light source device, and a display device. SOLUTION: A light reflecting sheet 7 which is supported by a support body for supporting light sources and reflects the light emitted from the light sources comprises through-holes which penetrate through in the thickness direction and long holes which are separated from the through-holes in the direction along the surface of the sheet and long in the direction of the separation. A light source device is provided with: first shaft bodies fitted in the through-holes to set the position of the light reflection sheet 7 relative to support body; and second shaft bodies fitted in the long holes so as to be movable in the direction of the length of the long holes to set the position of the light reflecting sheet 7 relative to the support body.

PROBLEM TO BE SOLVED: To provide a light guide plate device capable of eliminating generation of abnormal noise and display failure on a display surface owing to a plurality of light guide plates, to provide a light source device equipped with the light guide plate device, and to provide a display equipped with the light source device. SOLUTION: The light guide plate device includes an emission surface emitting light that has been incident thereto, a plurality of light guide plates 41 arranged in alignment, and band-plate coupling bodies 42 coupling respective light guide plates 41 in separation. The coupling body 42 restrains thermal expansion of the light guide plates 41, and gaps E between adjoining light guide plates 41 can be made in minute. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a liquid crystal display device which can enhance the dust-proofing property of a peripheral edge side of a liquid crystal panel in a configuration in which a peripheral edge of the liquid crystal panel is held on both front and rear sides by a frame edge of a front cabinet portion and a holder holding a peripheral edge rear side of the liquid crystal panel. SOLUTION: The liquid crystal display device includes: the liquid crystal panel 1 having a display surface 1a on its front side; a lamp 21 disposed on the rear side of the liquid crystal panel 1; a case body 22 housing and supporting the lamp 21; a cabinet 5 shielding the peripheral edge and rear side of the liquid crystal panel 1; and the frame-shaped holder 4 disposed on the rear side of the liquid crystal panel 1 in the cabinet 5 and holding the peripheral edge rear side of the liquid crystal panel 1. The cabinet 5 has a frame portion 51 disposed on the peripheral edge front side of the liquid crystal panel 1 and clamping the peripheral edge of the liquid crystal panel 1 on front and rear sides with the holder 4, and is provided with a dust-proof cylinder portion 10 protecting the part between the frame portion 51 on the peripheral edge side of the liquid crystal panel 1 and the peripheral edge of the case body 22 against dust, thereby enhancing the dust-proofing property of the peripheral edge side of the liquid crystal panel 1.

Abstract:
PROBLEM TO BE SOLVED: To provide a display device in which the aperture center of a cabinet and the center of a display screen of a display unit can be accurately aligned with a simple configuration. SOLUTION: A front cabinet 11 is fitted to the outer rim of a display unit 10 so as to cover the outer rim of a display unit 10 to allow a display screen 1a exposed through an aperture 11a. A plurality of sponge type elastic materials 3 are present between the inner circumference of the front cabinet 11 and the outer rim of the display unit 10 (for example, an upper part 111 of the inner circumference and an upper part 101 of the outer rim), so that even when misalignment occurs upon fitting the front cabinet 11, the center of the aperture 11a and the center of the display screen 1a can be automatically aligned by the elastic restoring force of the elastic materials 3.

Abstract:
PROBLEM TO BE SOLVED: To provide a light guide plate device, equipped with a plurality of light guide plates arrayed in parallel, capable of retaining parallel-arranged positions of the light guide plates which expand and contract by heat, and capable of allowing expanding and contracting of the light guide plates by heat, as well as a light source device equipped with the light guide plate device, and a display device equipped with the light source device. SOLUTION: In the light guide plate device, a plurality of light guide plates 42 each having a nearly rectangular shape and emitting light incident from a side surface of a short side from one side surface are arrayed in parallel on a support so as side surfaces of long sides to face each other, with one of the two short sides of each light guide plate 42 fixed with a male screw 25 onto the support, and the other fitted to each of a plurality of convex parts 24 for deciding the arraying position of the light guide plates 42 so as to be enabled to extend or contract to a length direction of a long side. Thus, the arraying positions of the light guide plates 42 are to be retained, and noise at the fixed parts of the light guide plates 42 is to be prevented. COPYRIGHT: (C)2011,JPO&INPIT
