[Prior art]
In recent years, with the widespread use of DVD players that have made it possible to increase the capacity of information, there are cases in which not only DVD video information is reproduced and viewed on a TV screen, but also DVD video information is displayed on a projector, for example. It is increasing. However, when a video is projected onto a screen using a projector, unlike a television, a clear video can often not be seen unless the room is darkened.
[0003]
As described above, when the DVD player is operated in a dark room, it is difficult to determine the function of the operation button on the front of the device, the function of the tray for inserting / removing the disc, or the function of the remote control button. However, it is troublesome to brighten the room each time the DVD player is operated. To alleviate such inconvenience, the player lights up a self-illuminating lamp to brighten the surroundings, and in the case of a remote control, a keypad with phosphorescent paint is used, or the remote control by backlight Products with the function of illuminating keys have been proposed.
[0004]
[Problems to be solved by the invention]
However, there is still no effective solution for the tray for loading and unloading the disk. In a dark room, it is difficult to determine the position where the disk is placed on the tray, or the position of the disk mounted on the tray and ejected. There is a problem that it is difficult to understand.
[0005]
The present invention has been made to solve the problems as described above, to obtain a recording and / or reproducing apparatus having a tray that can the be easily performed loading and unloading of the disc to the tray in a dark room For the purpose.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, a recording and / or reproducing apparatus provided with a tray according to the present invention has a recording function unit and / or a disk recording medium from a tray inlet / outlet of the apparatus main body in which the reproducing function unit is built. A tray that is loaded and moved to a discharge position and a storage position, a phosphorescent material that is arranged at least on the outer periphery of the disk storage portion of the tray, and a tray disposed above the tray in the apparatus main body. The light source is made to emit light, and the light source is turned on in conjunction with the tray discharge operation, the light storage material of the tray that is ejected from the tray inlet / outlet is made to emit light, and the light source is turned off after the tray discharge operation is completed It is made to let you.
[0009]
According to the recording and / or reproducing apparatus provided with the tray described above, the tray is turned on at the same time as the ejection operation is started by a command from the microcomputer by operating the eject switch, and the tray is turned on by the light from the light source. The phosphorescent material emits light upon irradiation. Accordingly, the tray is pulled out from the tray inlet / outlet in a state where the phosphorescent material is emitted, and the position of the disc housing portion can be clearly recognized by the emission of the phosphorescent material in the ejected tray. As a result, it is possible to easily load the disc into the tray and remove the disc from the tray even in a dark room. Further, although the light source is turned off after the tray is completely discharged, the light can be emitted for a predetermined time by the afterglow action of the phosphorescent material.
[0010]
When black light is used as the light source, the visible light is the light that has been cut, so even if the light from the light source leaks out from the tray slot during the tray ejecting operation, the light is hardly visible. Only the phosphorescent material is visible and it is extremely fantastic.

That is, according to the present invention, when the disc 6 having a disc diameter of 12 cm is loaded in the disc accommodating portion 7 a of the tray 7, the light storage materials 8 and 9 of the tray 7 are not covered with the disc 6. Thus, only the outer peripheral portion is exposed, and the phosphorescent material 8 on the outer peripheral portion of the disc housing portion 7 a is emitted by the light from the fluorescent lamp 10 and is drawn out from the tray inlet / outlet 5. Thus, the user can clearly recognize the position where the disc 6 is loaded by the ring-shaped light emission of yellowish green of the phosphorescent material in a dark room, and can easily take out the disc 6.
[0024]
Further, when the tray 7 is pulled out from the tray slot 5 with no disc loaded, the phosphorescent materials 8 and 9 of the tray 7 both emit light in a ring shape and the two disc storage portions. The positions of 7a and 7b can be recognized, and it is possible to easily load disks with different disk diameters.
[0025]
FIG. 5 shows an example in which the display surface of the disk 6 is displayed with a phosphorescent material 15 similar to the phosphorescent materials 8 and 9 formed on the tray 7 described above. In this case, the display surface may be a method of sticking a label printed by the phosphorescent material 15 on the non-recording surface of the disc 6 or a method of printing and displaying directly on the non-recording surface of the disc 6 by the phosphorescent material 15. .
[0026]
According to this, the disk 6 has the phosphorescent material 15 emitted by the light of the fluorescent lamp 10 and can recognize the presence of the disk 6, so that the disk diameter is 12 cm in the accommodating portion 7a of the tray 7 as shown in FIG. When the disc 6 is pulled out from the tray loading / unloading port 5, the phosphorescent material 15 of the disc 6 emits light together with the phosphorescent material 8 on the tray 7 side, and the presence of the disc 6 is more clearly recognized. Will be able to. The presence of a disk can also be clearly recognized in the same manner when a disk having a disk diameter of 8 cm is loaded in the accommodating portion 7b of the tray 7.
[0027]
Although not shown here, a phosphorescent material is not formed on the tray 7 side, and even if only the disc 6 emits light by the phosphorescent material, the presence of the disc loaded in each disc accommodating portion can be recognized. .
[0028]
Further, as shown in FIG. 7, the phosphorescent material 16, which is a plurality of markers on the outer peripheral portion of the disc accommodating portions 7a, 7b, except that the disc accommodating portions 7a, 7b are formed in a circle shape as the form of the phosphorescent material on the tray 7. 17 may be formed.
[0029]

[0030]
[Second Embodiment]
FIG. 9 is an external perspective view of a DVD player using a black light as a light source, and FIG. 10 is a sectional view of the same. The same components as those in the first embodiment are denoted by the same reference numerals.
[0031]
The black light 19 is a lamp having an emission spectrum peak close to 365 nm near the ultra-wavelength ultraviolet light emitted by the high-pressure mercury lamp, and emitting a wavelength range of 315 nm to 400 nm with strong photochemical action and fluorescence action, and absorbs visible light. It is covered with a dark blue filter glass that efficiently transmits ultraviolet rays in this wavelength range. Therefore, although the light emitted from the black light 19 is ultraviolet light and is hardly visible to the human eye, when the phosphorescent material is irradiated, the phosphorescent material can emit yellow-green light.
[0032]
That is, by using the black light 19 instead of the fluorescent lamp according to the first embodiment as a light source, the light storage material of the tray 7 or the light storage material of the disk drawn out from the tray inlet / outlet 5 emits light, and the disk is accommodated. The position of the disk and the disk itself becomes clear, and the disk can be easily loaded and removed in a dark room as in the case of the first embodiment described above.
[0033]
Further, by using the black light 19 as a light source, even if the light from the black light 19 leaks out of the tray inlet / outlet 5, it is not visible to the human eye, and only the phosphorescent material of the tray 7 or the phosphorescent material of the disk is used. It emits yellowish green and is extremely fantastic.
[0034]
[Third Embodiment]
FIG. 11 is an external perspective view of another type of DVD player using a black light 19 as a light source, and FIG. 12 is a cross-sectional view of the same, and the same components as those in the second embodiment are denoted by the same reference numerals. To explain.
[0035]
According to this, the light guide plate 21 made of, for example, acrylic resin having good light transmittance is supported so as to face the side of the black light 19 so as to penetrate the front panel 2, and the black light 19 is supported on the light guide plate 21. A filter 22 for absorbing visible light is provided on the light incident surface 21a on the side end surface. Further, an end surface of the light guide plate 21 protruding from the front panel 2 is formed on a light emission surface 21b inclined so as to face the tray 7 side.
[0036]
According to the above-described configuration, the light storage material of the tray 7 or the light storage material of the disc before being pulled out from the tray inlet / outlet 5 is caused to emit light by the light from the black light 19, and a part of the light of the black light 19 is filtered by the filter 22. After passing through the light guide plate 21, the light emitted from the light exit surface 21b is irradiated onto the tray 7 after being drawn out from the tray inlet / outlet port 5, and the light storage material of the tray 7 or the light storage material of the disc is subsequently emitted. By doing so, the light emission of the phosphorescent material further shines, and the disc accommodating portion and the disc itself can be recognized more clearly.
[0037]
Further, since the light of the black light 19 emitted from the light emitting surface 21b is not visible to the human eye, only the phosphorescent material of the tray 7 or the phosphorescent material of the disk is shining and becomes more fantastic.
[0038]
Furthermore, since the black light 19 emits the fluorescent paint vividly in a dark place, if the tray 7 and the disk 6 are treated with the light emitting material for black light, a colorful and fantastic atmosphere such as red, green, yellow, blue, etc. is created. In addition, you can enjoy the unique effects of black light.
