Abstract

A disc drive apparatus according to the present invention has a tray formed of an optically transparent material and has disc receiving portions. The tray is movable in an ejection and a retraction direction with respect to a casing. A light source is mounted inside the tray at the ejection direction side thereof. The light source emits light toward the ejection direction of the tray to cause the light to propagate within the optically transparent material from the retraction direction side through the ejection direction side of the tray with respect to the disc receiving portion.

Claims (10)

1. A disc drive apparatus comprising:

a casing,

a tray formed of an optically transparent material, including a disc receiving portion for a disc to be placed on and being movable in an ejection and a retraction direction in relation to said casing, said tray having a first reflection face reflecting light that enters said tray so as to illuminate a disk face of said disc placed on said disc receiving portion and said tray reflecting light that is reflected by said disc face so as to enter therein and thereby to radiate outward, and

a light source allowing light to enter said tray.

2. A disc drive apparatus as recited in claim 1 , wherein said tray has a second reflection face reflecting light that has entered therein by being reflected by said disc face of said disc so as to radiate outward.

3. A disc drive apparatus as recited in claim 1 , wherein said light source is mounted inside of said tray.

4. A disc drive apparatus as recited in claim 1 , wherein said tray has a luminous portion adopted to outwardly radiate the light emitted from said light source.

5. A disc drive apparatus as recited in claim 4 , wherein said luminous portion includes a front end portion of said tray with respect to the ejection direction.

6. A disc drive apparatus as recited in claim 4 , wherein said luminous portion includes a circumferential edge of said disc receiving portion.

7. A disc drive apparatus as recited in claim 3 , wherein said light source stays inside of said casing when said tray is ejected from said casing.
