Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an illumination device for a disc player for reproducing information recorded on a rotating, driven recording disc such as a compact disc or an analog record. It is.

2. Description of the Related Art In general, a compact disc used in a compact disc player known as a disc player has information recorded on one side and pictures, nine characters, etc. printed on the other side. This compact disc player is
The compact disc is rotated while the compact disc is held on a disk holding plate that is rotationally driven by a motor using the attraction force of a magnet, and the information recorded on the compact disc is reproduced by optical pickup. There is. In this Combaku I disc player, the compact disc is rotated and driven with the printed side of the 9 pictures and other characters facing up, and the information recorded side facing down, and the printed side is illuminated with continuous illumination light. I was trying to get it out.

Problems to be Solved by the Invention However, in the illumination device of such a conventional disc player, the printed surface of the compact disc is only illuminated with continuous illumination light while the compact disc is rotating. There was a problem that two characters etc. could not be read. In particular, since the compact disc player rotates the compact disc at high speed, it is impossible to read the nine characters on the printed surface at all.

Means for Solving the Problems In order to solve the above problems, the illumination device of the disc player of the present invention provides a lighting system for a recording disc that is rotationally driven.

This device is characterized in that the printed surface of characters and the like is illuminated with a strobe light at a period that is the same as or approximates the rotation period of the recording disk.

Function: When the lighting device of the present invention is synchronized with the rotation of the recording disk, the rotation appears stationary, and the two characters on the printed surface are legible.
Although it approximates the rotation period of the recording disk, if the rotation period is slightly shifted, the recording disk rotates at a much lower rotation speed than the actual rotation speed, and the two characters on the printed surface are still legible. be.

EXAMPLE Hereinafter, an example of the present invention will be explained with reference to FIGS. 1 to 4.

As shown in the figure, the compact disc 5 is fixed, rotated, and driven by a disc holding part 1a of a motor 1 and a magnet 3 guided by a disc center hole guide part 1b. A buffer material 16 made of nonwoven fabric or the like is pasted to prevent the magnet 3 from directly hitting the compact disc 5. Since the magnet 3 is bonded to the magnet holding disc 2, it rotates as the compact disc 5 rotates. Although the magnet holding disk 2 is housed in the case 4, it is not in contact with the case 4 during rotation. One hole 2a is provided in the magnet holding disk 2, and when it coincides with the hole 4a formed in the case 4 for each rotation,
The light from the lighting component 6 housed in the case 4 comes out of the case 4 and illuminates the printed surface 5a of the compact disc 5, such as pictures and two characters. The lighting component 6 is soldered to a printed wiring board 7, housed in the case 4, and fixed to the opening/closing lid 9. A transparent panel 1Q is adhered to the opening/closing lid 9, so that the inside can be seen through. The opening/closing lid 9 is rotatably supported by a case lid 11 with a hinge 11a. A printed wiring board 7 carrying a lighting component 6 is electrically connected to a main printed wiring board 12 housed in a case body 13 by a flexible wiring material 8. A switch component 14 for switching between operation and stop of the lighting component is soldered to the main printed wiring board 12, and by operating an operation button 16 from the outside, it is possible to control the lighting and clearing of the lighting. ing.

In the above embodiment, a compact disc player has been described, but it goes without saying that the same effect can be obtained by applying the same to other analog record playback machines.

In addition, in this embodiment, since the printed surface of the rotary recording disk is periodically illuminated with a strobe light according to the rotation of the disk, a magnet is used to hold the rotary recording disk against the disk holding plate of the motor. The magnet holding disk that holds the disc has a hole in one place, and the case that holds it has a hole in one place, so that the rotary recording disk is illuminated only when both holes match each rotation. However, such synchronous strobe illumination may be performed by electronic control.

Furthermore, it goes without saying that the illumination period may be controlled so as to deviate slightly from the rotation period of the rotary recording disk.

Further, as the transparent panel, a smoked or translucent material may be used to reduce the influence of external light.

Effects of the Invention As described above, the present invention has the advantage that the nine characters printed on the printing surface can be read while the recording disk is in operation, making it easier to confirm the information on the disk.
