  FIG. 6 is a diagram for explaining a state in which the pair of illumination members 40A and 40B having the configuration shown in FIG. The pair of illumination members 40 </ b> A and 40 </ b> B are attached to the disc tray 5 so as to sandwich the disc storage portion 15 from the left and right directions. Thus, by arrange | positioning a pair of illumination member 40A, 40B, each light-receiving part 41 is installed so that it may oppose at predetermined intervals. At this time, the optical path portions 42 of the pair of illumination members 40 </ b> A and 40 </ b> B are buried in the disc tray 5 so that only the three lens portions 43 </ b> A to 43 </ b> C and the light receiving portion 41 are exposed from the upper surface of the disc tray 5. . This is to prevent light that passes through the illumination members 40A and 40B from leaking from the optical path portion 42 and extra light from being input from the outside.

  By arranging the pair of illumination members 40A and 40B as shown in FIGS. 5 and 6, the front half of the disk storage portion 15 is surrounded by three lens portions 43A to 43C in total, three on the left and right. Therefore, by lighting these six lens portions 43A to 43C, it is possible to clearly recognize the position and state of the disc storage portion 15 in the disc tray 5 under illumination. Therefore, whether or not the optical disk 50 is stored in the disk storage unit 15 or what the content of the stored optical disk 50 is can be surely recognized visually.

  The number and arrangement of the lens portions are not limited to this embodiment. For example, the number of lens portions may be set to 5 or less, or may be configured to arrange 7 or more. Of course. The same applies to the arrangement of the lens portions. Of course, a desired lens portion can be arranged at the position. Further, the structure of the light emitting portion is not limited to the lens portion of this embodiment, and it is needless to say that other light emitting means can be used.

  As shown in FIGS. 5 and 6, the pair of light receiving portions 41 and 41 facing each other with a predetermined interval is supplied to the light guide member 20 in a state where the disc tray 5 has moved to the disc take-out position where the disc tray 5 has protruded most. It is comprised so that the lower surface 23a of the part 23 may be opposed. The light guide member 20 is fixed to the top plate 2a of the housing 2 by fixing means such as screws, and faces the upper surface of the decorative plate 9 when the disc tray 5 is moved to the most retracted disc mounting position. It is like that. A decorative frame 52 is fixed to the front end of the top plate 2a, and the visible portion 21 of the light guide member 20 is exposed from the lower portion of the decorative frame 52.

  Inside the light guide member 20, a light emitting diode 55 showing a specific example of the light source is disposed. As shown in FIG. 4 and the like, the light emitting diode 55 as a light source is mounted on a wiring board 56 of a control device (not shown), and is disposed opposite to the back surface of the light guide member 20 with a predetermined gap. The wiring board 56 is fixed to the upper surface of the disk drive device 4 by fixing means such as screws.

  The light emitting diode 55 shown in this embodiment has four radiating portions that emit light, and the four radiating portions are provided at predetermined intervals in the lateral direction. The reason why the four radiation portions are provided in this manner is that the two light receiving portions 41 are provided on the disc tray 5. In other words, the two radiating parts are necessary for supplying light to the two light receiving parts 41 individually, and the remaining two radiating parts are the second input parts opposed to the two light receiving parts 41. This is because the two first light incident surfaces 27a for the illumination unit 22 are provided on both outer sides of the light surface 27b.

  Thus, as shown in FIG. 4, most of the four lights (light fluxes) emitted from the light emitting diode 55 are incident on the light guide member 20. The first light incident surface 27a is incident, and the remaining two light beams are incident from the second light incident surface 27b. The light incident on the first light incident surface 27a is reflected by the first lower reflection surface 28a, further reflected by the first upper reflection surface 28b, and travels like the upper optical path M1. As a result, a part of the light L1 moving on the optical path M1 side is emitted from the visible portion 21. Further, the remaining lights L2 and L3 moving on the optical path M1 side are emitted to the outside from the inner surface 22a of the illumination unit 22.

  On the other hand, the light incident from the second light incident surface 27b of the light guide member 20 is reflected by the second reflecting surface and travels like a lower optical path M2. As a result, the light L4 that moves on the optical path M2 side and exits from the lower surface 23a travels through the decorative plate 9 and is reflected by the concave sculpture 11 in the storage state of the disc tray 5, and the concave sculpture 11 is reflected by illumination. Make it rise. Further, in the state where the disc tray 5 is popped out, the light L4 emitted from the lower surface 23a of the supply unit 23 is input to the two light receiving units 41, respectively. As a result, the light passing through the two optical path portions 42 emits light from the lens portions 43A to 43C, and the periphery of the disk storage portion 15 is illuminated by the light emitted from the lens portions.

  The light source is not limited to the light emitting diode described in this embodiment, and it is needless to say that a light emitting lamp or other light source can be used.

The DVD device 1 including the lighting device having such a configuration can be used as follows, for example.
Generally, this type of DVD device 1 is used when watching a movie or the like in a dim room. Therefore, for example, when watching a movie for a long time, an optical disk replacement operation or the like is often performed in a dim state.

  At this time, according to the present invention, when the lid 3 is opened and the upper part of the front surface of the housing 2 is opened, the decorative plate 9 fixed to the front surface of the disc tray 5 and the housing 2 are provided as shown in FIG. The first and second operation button groups 12A and 12B and the display unit 13 provided on the front surface of the screen are exposed. Therefore, the power button provided on the housing 2 or the power button provided on the remote control device is turned on to turn on the DVD device 1. As a result, light is emitted from the light-emitting diode 55 that is a light source through the operation of the control device, the light is supplied to the light guide member 20, and the visible portion 21 emits light. Thereby, it can be known that the power of the DVD device 1 has been turned on, and the on / off of the power can be visually confirmed by checking the visible portion 21 (power indicator).

  Further, for example, when taking a viewed optical disc from the disc storage portion 15 of the disc tray 5, the light emitting diode 55 is operated to supply light to the light guide member 20. In this case, as shown in FIGS. 2 to 4, when the disc tray 5 is pushed into the disc mounting position, the entire illumination portion 22 of the light guide member 20 shines. Is illuminated (disc illumination). Accordingly, the second operation button group 12B provided below the opening 7 is illuminated, and the front surface of each operation button is bright and easy to see.

  As a result, the display of each operation button of the second operation button group 12B can be made clear, and the function of each operation button (for example, HDD recording 1, HDD recording 2, disk recording, recording reservation, etc.) is clarified. Thus, it is possible to prevent an erroneous operation from occurring. At the same time, since the light supplied to the supply unit 23 of the light guide member 20 is reflected by the concave sculpture 11 of the decorative board 9 and shines, the concave sculpture 11 appears to float from the front. As a result, the characters engraved on the decorative board 9 can be visually recognized (floating character illumination).

  On the other hand, as shown in FIGS. 1 and 5, when the disk tray 5 is in the state of being pulled out to the disk take-out position, the light emitted from the light emitting diode 55 is paired with the illumination from the supply unit 23 of the light guide member 20. It inputs into each light-receiving part 41 of member 40A, 40B. Then, the light input to each light receiving portion 41 passes through the respective optical path portion 42 and travels to the front end side, and part of the light is reflected by the lens portions 43A, 44F, 44F, 44F, respectively at the three reflecting portions 44C, 44E, 44F. Reflected to the 43B and 43C sides. As a result, the six lens portions 43A to 43C emit light simultaneously, and the disc storage portion 15 is illuminated by the light emission of the six lens portions 43A to 43C (tray illumination). Thereby, even in a dark room, it is possible to easily perform the operation of taking out the optical disk from the disk storage unit 15, the mounting work, and the like.

  In the present invention, a transparent member for guiding the light from the light source is required inside the disc tray 5, but since the illumination can be performed without performing electrical parts and wiring, the entire illumination device There is an advantage that the structure can be simplified. Further, the present invention does not have to be configured to satisfy all of the above-described four functions (power indicator, disk illumination, floating character illumination, and tray illumination), as long as at least two of these functions are satisfied. It ’s good. Further, in the above embodiment, the color and luminance of the light source are not mentioned, but it is needless to say that it can be arbitrarily adjusted according to the state.

  The light emitting diode 55, the light guide member 20, the decorative plate 9, and the two lighting members 40A and 40B, which are the light sources, constitute the lighting device of the present invention. However, it is not necessary for the lighting device to satisfy all of the above elements, and the lighting device of the present invention can be configured as long as it has at least the light emitting diode 55 and the light guide member 20. The electronic device of the present invention is not limited to the above-described DVD device. For example, various electronic devices (for example, televisions) that need to easily illuminate an operation panel, operation buttons, and other parts. , Stereo devices, etc.). Furthermore, in the said Example, although the example which provided the illuminating device in the housing | casing 2 was demonstrated, of course, it is good also as a structure which provides an illuminating device in the cover body 3. FIG.

  As described above, according to the present invention, the light emitted from one light source is configured to be distributed in various directions using the reasonably arranged reflecting surfaces. Therefore, at least two of the power indicator, disk illumination, floating character illumination, and tray illumination can be efficiently exhibited, and the lighting equipment for the operation panel and the disk loading / unloading portion can be realized with a simple configuration. In addition, the operation of the operation buttons and the operation of attaching / detaching the disc can be performed under bright illumination, and the operability can be improved.
