Disk Tray Assembly of Disk Player

The present invention relates to a disc tray assembly installed for carrying a disc in a disc player, and more particularly to a disc tray assembly of a disc player having holders for preventing the disc from being detached.

A disc player for reproducing information recorded on a disc is generally provided with a disc tray assembly for carrying the disc in and out of the disc player body. An example of such a disc tray assembly is shown schematically in FIGS. 1 and 2. Referring to the drawings, the disc tray assembly 1 has a plurality of tray bodies 2 having a disc receiving portion 2a and a plurality of hinges 3a joined around the disc receiving portions 2a of the tray body 2. Holder 3 is provided. Each of the holders 3 is arranged between a first position where its free end protrudes toward the disc receiving portion 2a as shown in FIG. 1 and a second position which is out of the disc receiving portion 2a as shown in FIG. 2. Can be rotated. Each holder is elastically biased toward the first position by a torsion spring 4 whose one end is supported by the tray body 2 and the other end is supported by the holder 3. Reference numeral 3b denotes a guide protrusion formed on the bottom surface of the holder 3 for guiding the position of the disc 9 accommodated in the disc accommodation portion 2a. Reference numeral 2c denotes a protrusion accommodating portion formed in the tray body 2, and the entrance and exit portion of the protrusion accommodating portion 2c is allowed to enter and exit the guide protrusion 3b by an external force of a predetermined size applied to the holder 3. The width is elastically deformable. When the guide projection 3b of the holder 3 is accommodated in the projection accommodation portion 2c, the holder 3 is opposed to the elasticity of the torsion spring 4 and is shown in the second position as shown in FIG. Can be fixed at

When such a disc tray assembly 1 is installed in a disc player of the type in which the disc 9 is upright and conveyed, the disc tray assembly 1 is detached from the disc accommodating portion 2a while the disc accommodated in the disc accommodating portion 2a is transported. Since the holder 3 needs to be prevented, the holders 3 are used in the first position. Thus, the process of accommodating the disk 9 in the disk accommodation portion 2a in the state where the holders 3 are located in the first position will be described with reference to FIGS. 3, 4 and 1. In FIG. 3 and FIG. 4, for convenience of description, reference numerals given to holders positioned below and holders positioned above are different from each other in the drawings.

First, as shown in Fig. 3, the disc 9 is inserted from above from between the holders 3x positioned below in the drawing and the bottom surface of the disc receiving portion 2a, and through the disc 9, the lower holder. Press the guide protrusions 3b of (3x). Accordingly, the lower holders 3x are rotated by a predetermined angle to the second position side as shown in FIG. 4 while elastically deforming the torsion spring 4, and the upper portion of the disk 9 is larger than the upper holders 3y. It is located in the lower side in the drawing. In this state, when the upper portion of the disk 9 is brought into close contact with the bottom surface of the disk receiving portion 2a and then released from the disk 9, the lower holder is held by the torsion springs 4 which have been deformed elastically. (3x) are rotated again to the first position side, the disk 9 is moved upward, that is, between the upper holder (3y) and the bottom surface of the disk receiving portion (2a), the upper and lower holder (3y, 3x) As a result, separation from the disc accommodating portion 2a is prevented.

As described above, in the above-described disc tray assembly 1, the holders 3 are elastically biased to the first position by the torsion spring 4 so that the holders 3 may be manually operated to prevent the disc 9 from being received and detached. It is possible to eliminate the hassle of having to rotate directly by.

On the other hand, when the disc tray assembly 1 is applied to a disc player of the type in which the disc 9 is horizontally transported, the disc 9 is the disc receiving portion of the tray body 2 while the disc 9 is being transported. Since there is no fear of detachment from (2a), the holders 3 may be positioned and used in the above-mentioned second positions, respectively.

By the way, in the above-mentioned conventional disc tray assembly, a torsion spring is used as an elastic means for elastically biasing each holder to protrude toward the disc receiving portion side, and thus the assembly work of the disc tray assembly is complicated, There is a problem that the number is increased and the manufacturing cost is increased.

In addition, in the case where the disc tray assembly 1 is applied to a disc player in which the disc 9 is horizontally transported, as described above, the holder 3 is positioned at the second position, respectively, and the disc accommodating portion is provided. In order to accommodate the disc, the diameter of the disc accommodating part must be considerably larger than the diameter of the disc, in view of the fact that the disc is applied to the disc player in a vertically transported form to accommodate the disc in the above-described manner. The disk accommodated in the disk receiving portion can flow largely in the radial direction so that the position of the disk is displaced during transportation of the disk. When the position of the disc in the disc receiving portion is greatly distorted as described above, the disc may not be correctly chucked when the disc is mounted into the disc player body and then chucked by the chucking device installed in the disc player body.

The present invention has been made to solve the above problems, the elastic bias in the direction protruding to the disk receiving portion the holders installed on the tray body rotatably between the position protruding to the disk receiving portion and the position away from the disk receiving portion. It is an object of the present invention to provide a disc tray assembly of a disc player which is capable of significantly reducing the flow of the disc when the holder is used in a fixed state at a position away from the disc receiving portion.

First, referring to FIGS. 5 and 6, the disc tray assembly 10 of the present embodiment is the same as the conventional disc tray assembly 1 described with reference to FIGS. 1 to 4. In addition, it is applicable to a so-called vertical type disc player in a form in which the disc is held upright, and includes a tray main body 20 having a disc accommodating portion 21 for accommodating the disc 9 and a disc of the tray main body 20. Holders 30 arranged around the receiving portion 21 are provided. A hinge shaft 31 protrudes from the bottom of each holder 30, and elastic portions 31a that are elastically deformable are provided at the tip of the hinge shaft 31. Locking jaws 31b are formed at free ends of the elastic parts 31a, respectively. The hinge shaft 31b is rotatably fitted in the hinge hole 29 formed in the tray body 20 so that the holder 30 protrudes toward the disc accommodation portion 21 as shown in FIG. And the position deviating from the disc receiving portion 21 (hereinafter referred to as the second position) as shown in FIG. 8. Meanwhile, the elastic parts 31a are elastically deformed while the hinge shaft 31 is inserted into the hole of the tray body 20, and the hinge shaft 31 is fully fitted into the hinge hole 29 of the tray body 20. 7, the catching jaw 31b is caught by the bottom surface of the tray main body 20 as shown in FIG. 7, thereby preventing the holder 30 from being separated.

The guide protrusions 32 protrude from the bottom surfaces of the holders 30, and the tray body 20 accommodates and supports the guide protrusions 32 in a state in which the holder 30 is located at the second position. The protrusion accommodating part 23 is formed. The protrusion accommodating part 23 is elastically deformable so that the width | variety of the entrance part may be elastically deformed so that the guide protrusion 32 may enter and exit the said protrusion accommodating part 23 by the external force of the predetermined magnitude | size applied to the holder 30. . When the holder 30 is located in the second position, the elastic deformation part 33 is elastically deformed and has a restoring force, and the guide protrusion 32 is accommodated in the protrusion receiving part 23 of the tray body 20. By being supported, the holder 30 can be fixed in its second position against the restoring force of the elastic deformation portion 33.

On the other hand, unlike the conventional disc tray assembly 1 described above, in the disc tray assembly 10 according to the present invention, each holder 30 is formed with an elastic deformation portion 33 and the protrusion 35. .

The elastic deformation portion is formed to extend integrally from the body of the holder 30 and has a suitable thickness so that it can be elastically deformed, and the end of the elastic deformation portion 33 has a support 22 formed in the tray body 20. Supported by). The elastic deformation part 22 causes the holder 30 to be elastically biased toward the first position in the direction in which the holder 30 protrudes toward the disc receiving part 21.

As shown in FIG. 8, the protrusion 36 protrudes into the disc receiving portion 21 of the tray body 20 when the holder 30 is located at the second position. Is opposed to the outer circumferential surface of the disk 9 accommodated in the disk accommodation portion 21 in the state where it is located in the second position.

When the disc tray assembly 10 configured as described above is installed in a disc player of a type in which the disc is held upright, the disc tray assembly 10 is separated from the disc accommodating portion 21 while the disc accommodated in the disc accommodating portion 21 is transported. Since it is necessary to prevent, the holders 30 are used in the first position. In order to accommodate the disc 9 in the disc accommodating portion 21 in the state where the holders 30 are located in the first position as described above, the disc 9 is mounted as in the disc tray assembly 10 described above. The guide protrusions 32 of the lower holders are pressed by being inserted between the lower holders in the figure and the bottom surface of the disk accommodation portion 21. Accordingly, the lower holders are rotated to the second position, at which time the elastic deformation portions 33 of the holders are elastically deformed. Thereafter, when the disk is brought into close contact with the bottom surface of the disk receiving portion 21 and the hand is released from the disk, the lower holders are rotated back to the first position by the elastically deformable elastic deformation portion 33 and the disk ( 9) upwards, that is, between the holders located at the upper side in the figure and the bottom surface of the disc accommodation portion 21. Accordingly, the disk 9 is elastically supported by the guide protrusions in contact with the outer circumferential surface thereof, and is prevented from being separated from the disk accommodating portion 21 by the free ends of the upper and lower holders 30. Will be.

On the other hand, in the disc tray assembly 10 of the present embodiment, when the holders 30 are placed in the second position, the disc 9 is accommodated in the disc accommodating portion 21 or in the disc accommodating portion 21. No interference by the holders 30 taking out the disk 9 accommodated in the < RTI ID = 0.0 > Therefore, when the disc tray assembly 10 is applied to a disc player in which the disc is horizontally transported, there is no fear that the disc may be detached from the disc accommodating portion 21 of the tray body 20 while the disc is being transported. In this case, the second position may be fixed and used in the above-described manner. At this time, the projections 35 of the respective holders 30 face the outer circumferential surface of the disk 9 accommodated in the disk receiving portion 21, so that the disk 9 is moved in the radial direction during the transport of the disk 9. It is brought into contact with the protrusion 35 when flowing, ie when flowing on a horizontal plane. Therefore, in view of the fact that the disk is applied to a disk player in a vertically transported form to accommodate the disk by the above-described method, the diameter of the disk accommodation portion 21 is formed considerably larger than the diameter of the disk 9. Even so, the projections 35 make the flow width of the disk 9 within the disk receiving portion 21 small, so that the disk 9 is in a substantially fixed position during the transport of the disk 9. Will be located.

In this embodiment, in order to fix each holder 30 in the second position, the projection body 23 is provided in the tray body 20 to elastically receive the guide projection 32 of each holder 30. However, the holder 30 is not necessarily fixed to the second position only by such a configuration, and various other configurations may be appropriately applied to the disc tray assembly of the present invention.

As described above, the disc tray assembly of the present invention is a means for elastically biasing holders rotatably installed in the tray main body in a direction protruding toward the disc receiving portion to prevent the disc from being detached, and extends from each holder. By providing an elastic deformation portion supported at the end of the tray body, it is not necessary to provide a separate spring member, thereby simplifying the assembly process and making it possible to manufacture at low cost. Further, since the holders have projections protruding toward the disc receiving portion when the holders are positioned in the second position and opposing the outer circumferential surface of the disc accommodated in the disc receiving portion, the flow of the disc during conveyance of the disc accommodated in the disc receiving portion. This will be greatly reduced.
