Abstract
A panel light-emitting structure includes a front panel, a light guide plate, a light-emitting portion, a guide, etc. The light guide plate is formed in a transversely elongated shape having a long side and a short side, and includes an elongated hole extending in a direction of the long side. This forms two light transmission areas. A notch is provided outside the elongated hole at the short side section. This enables an incident light from an LED to the light transmission areas. An outer surface of the light guide plate is formed by an R curved surface. Accordingly, almost all of the light from the LED is totally reflected by the outer surface.
Claims14
A light guide plate made of a light-transmittable material, and formed in a transversely elongated shape having a long side and a short side for making a light from a light source enter from said short side to transmit it to said long side, comprising:
- two light transmission areas which are vertically divided from each other and with which an elongated hole formed to be extended in a direction of said long side is sandwiched, and
- a light enter portion formed at said short side for guiding the light from said light source to said light transmission area, wherein
- said long side is inclined so as to be narrower toward said short side at least at an end section of said short side.
A disk drive comprising:
- a housing formed with a disk loading slot taking a shape of an elongated hole;
- a light guide plate formed with an elongated hole;
- and
- a light source for causing said light guide plate to emit a light, wherein
- said light guide plate is arranged in said housing such that at least a part thereof is exposed from said disk loading slot, and is arranged at a positional relationship where said elongated hole and said disk loading slot are overlapped with each other when viewed from a disk loading direction.
A disk drive comprising:
- a housing formed with a disk loading slot taking a shape of an elongated hole;
- a light guide plate formed with an elongated hole;
- a light source for causing said light guide plate to emit a light, and
- a member detachably attached to said housing, wherein
- said member covers at least a part of an outer surface of said light guide plate, and
- said member is detachably attached with said light guide plate.
