[Detailed description of the invention]

llAg! ! 2. Description of the Related Art Conventionally, so-called workstations and the like have been equipped with a disk playback device configured to allow a compact disk such as a CD-ROM to be loaded in a vertical plane and played back. In such a disc playback device, the disc is mounted by placing the disc on a front plate that can be opened and closed with respect to the main body, and closing the front plate. However, with the above configuration, it is necessary to flip the disc removed from the disc case when installing it, and in order to check the label display of the installed disc, you must open the front panel and then remove the disc. Therefore, in the present invention, a saucer for holding the disk is slidably attached to the fixed main body side, not on the front plate side which can be opened and closed, and the disk is mounted using the tray. do. As a result, it is possible to check the label display without removing the disc during the reversing operation or when the front plate is open. Furthermore, the sliding movement of the receiving tray is achieved by also using an oil damper that opens and closes the front plate, thereby realizing smooth installation at low cost. INDUSTRIAL APPLICATION FIELD The present invention relates to a disk playback device for playing back a disk-shaped recording medium such as a compact disk, and in particular, a disk playback device in which the disk-shaped recording medium is mounted in a vertical plane is equipped, and The present invention relates to a disk-shaped recording medium mounting device that is suitably implemented as a mechanism for mounting a disk-shaped recording medium. 2. Description of the Related Art Conventionally, in so-called workstations, there has been a disk playback device having a compact disk (hereinafter referred to as a "disk") such as a CD-ROM, which is mounted in a vertical plane and played back. A so-called vertical disc playback device is known. Fig. 5 is a perspective view showing a simplified configuration of a conventional disc playback device 1. In Fig. 5, a disc 2 to be played and the disc are Disc booth 3 to be stored
is also shown. The disc playback device 1 includes a main body 4 that is fixed in advance, and a front plate 5 that can be opened and closed with respect to the main body 4. A gear 15 is provided on the rotation axis of the front surface W5, and an air damper 1 provided in the main body 4
Opening/closing is performed by 6. The main body 4 includes a turntable 6 that is the center of rotation of the disk 2 mounted thereon, a pickup 7 that is movable in a radial direction around the turntable 6, a drive device 8 that moves the pickup 7, and the like. It is arranged. Furthermore, a reproduction device (not shown) is incorporated in the main body 4. The front plate 5 also includes a clamper 9 that rotatably holds the disc 2 between it and the turntable 6 when the disc 2 is mounted, and a clamper 9 that serves as a positioning structure for the disc placed when the disc 2 is mounted. The support member 10 is included. When the operator takes out the disc 2 to be played from the disc booth 3, the operator places the center of the disc 2 and the clamper 9 facing each other, and further brings the outer circumferential surface of the disc 2 into contact with the inner circumferential surface of the curved support member 10. Place them so that they are touching each other. Thereafter, by closing the front plate 5 with respect to the main body 4, the disc 2 is held between the turntable 6 and the clamper 9, and the installation of the disc 2 into the disc reproducing apparatus 1 is completed. Problems to be Solved by the Invention Generally speaking, one surface of a disc 2 is a label surface 2a that displays what information is recorded on the disc 2, and the other surface is a label surface 2a that displays information to be reproduced. This is the recorded information surface 2b. When the operator places the disk 2 into the disk case 3, the operator places the disk 2 while facing the label surface 2a, as shown by the two-dot chain line 11. On the other hand, when the disc 2 is loaded into the disc playback device 1, it must be loaded so that the information surface 2b of the disc 2 faces the pickup 7. Therefore, as described above, the clamper 9 of the front plate 5
When placing the disk 2 thereon, the label surface 2a of the disk 2 is placed so as to face the clamper 9, as shown by the two-dot chain line 12. Therefore, when the operator places the disc 2 into the disc case 3 and when loading the disc 2 into the disc playback device 1, the operator must place the disc 2 while facing opposite surfaces, and the disc 2 to 1
The f1 operation of rotating by 80 degrees, that is, the reversing operation is required, and the operation is complicated. Furthermore, since the reversing operation is required, the operator is likely to handle the disc 2 by pinching it with his or her fingertips, which tends to contaminate the information surface. As a result, sound quality deterioration and information reading errors occur. Furthermore, although the front plate 5 is generally provided with a window for checking whether or not a disc is mounted, the window is relatively small in order to prevent laser light from leaking from the pickup. In the closed state, the display on the label surface 2a of the disc 2 cannot be confirmed through the front plate 5. Therefore, in order to confirm the display on the label surface 2a of the mounted disc 2, the operator must: - The front panel 5 will be opened from the main body 4. However, in the spaced state, the disk 2 is placed with the label surface 2a facing the clamper 9 as described above, so unless the disk 2 is taken out and reversed, the display on the label surface 2a will be exposed. In other words, the operation for confirming label display is also complicated. Further, as described above, the disk 2 is mounted on the disk playback device 1 in such a manner that the outer peripheral surface of the disk 2 is brought into contact with the curved support member 10 provided on the front plate 5 and the disk 2 is placed on the clamper 9. This is done by closing the front plate 5 to the main body 4. Because of this configuration, for example, when the front plate 5 is closed forcefully or when the main body 4 is installed diagonally, the disk 2 that was placed a can be moved to the curved support member 10. Problems such as the disc coming off may occur, resulting in the disc not being able to be installed correctly. As a result, the disk may be damaged. Therefore, an object of the present invention is to enable label display to be confirmed without requiring a reversing operation when mounting a disc-shaped recording medium, and without removing the mounted disc, and to further ensure reliable mounting. An object of the present invention is to provide a mounting device for a disk-shaped recording medium. Means for Solving the Problems The present invention provides a method for mounting a disk-shaped recording medium in which a clamper is provided on a front plate that can be opened and closed to press the central part of the disk-shaped recording medium against a turntable so that it can rotate freely. The apparatus includes: a tray that is slidably attached to the main body and holds the disk-shaped recording medium; and an interlocking means that moves the tray in conjunction with opening and closing of the front plate. This is a disk-shaped recording medium mounting device characterized by the following. According to the disk-shaped recording medium mounting device of the present invention, a front plate that can be opened and closed with respect to the main body is provided, and the front plate is provided with a front plate that allows the central part of the disk-shaped recording medium to be attached to the tar table provided in the main body. In one aspect of the present invention, which is provided with a clamper that rotates C1 while pushing f, a tray for holding the disc-shaped recording medium is further attached to the main body so as to be slidable with respect to the main body. The tray is moved down by the drive stage '4' in conjunction with the rM lever to the main body of the front plate. As a result, when the front plate is in an open state with respect to the main body,
when the tray holds the disc-shaped recording medium;
On the other hand, when the front plate is in an open state with respect to the main body, the tray opens the disc-shaped recording medium, and the disc-shaped recording medium is held between the clamper and the turntable and is rotatably held. Ru. Therefore, when loading a disc-shaped recording medium, the operation sound can be heard by simply holding the disc-shaped recording medium in the tray while facing the surface on which the label is marked (i. When the installation is completed, the disc-shaped recording medium is held by the tray with the surface on which the label is attached facing outward, so when the front panel is open, it is necessary to check the label. Further, the disk-shaped recording medium is held by the tray until the front plate is closed, and the tray is slidable in conjunction with the opening and closing of the front plate by the interlocking means. The center part is reliably held between the turntable and clamper and accurate positioning is achieved, regardless of the force of closing the front plate or the inclination of the main body. Embodiment Fig. 1 is a perspective view showing a simplified configuration of a disc playback device 21 equipped with a mounting device according to an embodiment of the present invention. It is installed in a disc reproducing device 21. In addition to the disc reproducing device 21, FIG. 1 also shows a disc 22 and a disc case 23 that is a storage container for the disc 22. 24 houses a driving device for moving the pickup 26 and other playback circuits, and the internal structure is shielded from the outside by a shielding plate 27. Near the center of the main body 24, a shielding plate is provided. A turntable 28, which is the center of rotation of the disk 22, is provided protruding from the plate 27, and a long hole 29 is provided in a certain radial direction centered on the turntable 28.The long hole 29

[In addition, the main body 24 and the front plate 25
An m-lock structure (not shown) is provided between the
The front plate 25 is locked to the main body 24 in the closed state. In this embodiment, the main body 24 is further provided with a saucer 31 that slides with angular displacement relative to the main body 24 as the front surface W, 25 opens and closes, as will be described later. FIG. 2 is a side view of the disc playback device 21 showing the arrangement of the tray 31, and FIG. 3 is a diagram showing a simplified structure of the tray 31. Note that FIG. 3(2) is a sectional view taken along the section line AA in FIG. 3(1) showing a plan view of the saucer 31. The saucer 31 is made of, for example, plastic or ABSII resin, and has a side circumferential portion 3 perpendicular to the outer circumferential portion of the circular bottom portion 32.
It is formed from a so-called tray-shaped body on which 3 are erected. The circular contour formed by the inner circumferential surface 33a of the bait surrounding portion 33 is selected to be the same as the contour of the disk 22 to be placed, and the saucer 3] is designed to hold the disk 22 to be placed. Height 11 of the side peripheral part 33 from the bottom part 32 (Fig. 3 (2)
)1) is selected to be slightly larger than the thickness of the disk 22. On the predetermined circumference of the saucer 31, that is, in the upper part (:f) of FIG.
A connecting member 34 is provided to connect the saucer 3 to the tray 3. The connecting member 3/l is the base! 335, and a locking piece 37 that is formed to protrude from the base 35 and has an insertion hole 36. In FIG. 3, the locking pieces 37 are provided at both ends of the base 35, respectively. A shaft portion 38 fixed in advance to the upper part 01 (h'ji 111g in FIG. 2) of the main body 24 is inserted into the insertion hole 36 of the locking piece 37, and the shaft portion 38 is rotated about the shaft portion 38 as a center of rotation. , the saucer 31 slides with an angular displacement relative to the main body 24. Further, on the diagonally lower side of the saucer 31 (see FIG. 3), at the diagonal upper end of the main body 24, which roughly forms a tetrahedron, there is a groove that prevents the saucer 31 from sliding as the front plate 25 opens and closes. Three interlocking members for adjustment are provided.The interlocking member 39 includes a saucer gear 40 fixed to the saucer 31;
The front plate gear 42 is configured to include a semicircular arc-shaped front plate gear 42 whose rotation center is the rotation axis 41 of the front plate 25, and an oil damper 43. The saucer gear 40 extends along the circumferential direction centering on the shaft portion 38 of the connecting member 34, and further has a * 40 a formed in a portion facing the front plate 25. The teeth 43a of the oil damper 43 are in contact with the teeth 40a of the saucer gear 40, and the teeth 43a of the saucer gear 40 are also in contact with the teeth 40a of the saucer gear 40.
i and t mesh with v142a of the front plate gear 42. In this way, as shown at 211, when the front plate 25 is brought into the closed state, it is pushed up in the direction of the arrow 50 with a finger. By doing so, the front plate gear 42 rotates in the direction of arrow 46 and the saucer gear 40 slides in the direction of arrow 45. As a result, the saucer 31 is also angularly displaced about the shaft portion 38 in the direction of arrow 45. Since the saucer gear 40 has an oil damper 43, it enables smooth sliding of both the front plate 25 and the saucer 31. When the front plate 25 is in the open state, move the front plate 2 in the opposite direction of the arrow 50.
The angle 'RCii is due to the dead weight of 5. By doing this, the front plate gear 42 rotates in the direction of arrow rF51, and the saucer gear 40 slides in the direction of arrow 52. As a result, the saucer 31 is also angularly displaced about the shaft portion 38 in the direction of arrow 52. i) Since the saucer gear 40 is fully engaged with the oil damper even in this four-way position, smooth sliding of both the front plate 25 and the saucer 31 is possible. thus,
Since the interlocking member 39 interlocks and slides the front plate 25 and the tray 31 based on the rotational drive of the oil damper 43 of 111I, smooth movement can be realized with a small number of parts. Further, an opening 47 is formed near the center of the bottom surface 32 of the saucer 31. The opening 47 allows the tar table 28 to protrude from the bottom surface portion 32 as described later when the front plate 25 is open with respect to the main body 24 as described above, and further allows the pickup 26 to protrude from the bottom surface +132.
Touch the surface of the disk 22 facing the I! It is shaped so that it can be viewed for reading. Further, on a predetermined inner circumferential surface of the side circumferential portion 33 of the saucer 31 and at a portion opposite to each other on the diametrical line, a notch 48.4 is provided.
9 is formed. In the cutout portions 48 and 49, the bottom portion 32 is cut radially inwardly than the other side peripheral portions. The notches 148 and 49 are Wi areas for holding the outer circumferential surface of the disk 22 with your fingertips when placing the tape 22 on the tray 31''41 or when not taking out the disk 22 from the tray 31. Consideration has been given to making it easy to place and take out the disk without touching the information surface.Referring again to FIG. The other surface is an information surface 22b on which information to be reproduced is recorded.The disk case 23 is attached to the base 23a and the base 231t. The operator holds the disc 22 with the label surface 22a facing the label surface 22a as shown by the two-dot chain line 50, that is, with the information surface 22b facing the base 23a. In this embodiment, when loading the disc 22 into the disc playback device 21, the operator can also do so while facing the label surface 22a. As shown by the two-dot chain line 51 in Figure 1, the main body 24
h/t) The saucer 31 head disk 22 is arranged to protrude.
is placed with the information surface 22b on the bottom surface part 32, and the disk 22 is held by the saucer 31,
Attachment is performed by closing the front plate 25 as described later. Therefore, there is no need for the conventional reversing operation, which is used separately when storing a disc in a disc case and when loading it into a playback device. FIG. 4 is a schematic diagram for explaining the operation of mounting the disk 22. FIG. 4(L) shows that the front plate 25 is in an open state with respect to the main body 24. When the front plate 25 is in the open state, the saucer 31 is separated from the pickup 28 of the main body 24, and the saucer 31 is moved toward the disk 22.
When the information surface 22b of the disk 22 is placed, the information surface 22b of the disk 22 opens into the opening 4.
The turntable 28 is viewed through 7. On the other hand, FIG. 4 (2) shows that the front plate 25 is in an open state with respect to the main body 24. As shown in FIG. 4(1), the front plate 25 is attached to the main body 24 by the operation of the interlocking member 39, as described above, on the side where the disk 22 is placed on the saucer 31.
When the tray 31 is closed, the tray 31 slides. Fourth
Referring to the figure, as shown in FIG. 4 (1), the saucer 31 placed on the left side of the turntable 28, after sliding,
As shown in FIG. 4 (2), the turntable 28 is passed through the opening 47 and placed on the right side of the turntable 28.
IL! ! When the saucer 31 passes on a flat surface, the disk 22 placed on the bottom part 32 passes through the central hole 22C formed in the center of the turntable 28 through the protrusion 28 of the turntable 28.
a, and the radially inner circumferential surface of the information surface 22b is brought into contact with the turntable 28. In this way, the disk 22 is switched from the tray 31 to the turntable 28 and supported. That is, the tray 31 that slides to the right side of the turntable 28 (see FIG. 4 (2)) does not restrain the disk 22. Thereafter, the clamper 30 provided on the front plate 25, which has been closed with respect to the main body 24, comes into contact with the radially inner peripheral side of the label surface 22a of the disc 22, clamps the disc 22 between the turn-chip pulls 28ε, and rotates the disc 22. Support freely. Therefore, the disc 22 can be securely placed on the turntable 28.
The center portions can be placed opposite each other, making positioning very easy. After being supported as described above, the information is read and reproduced by the pickup 26 which faces the information surface 22b of the disk 22 through the opening 47. In addition, since the saucer 31 and the disk 22 are mounted on the fixed main body side, rather than on the front plate side which can be opened and closed freely, the disk 22 is placed on the fixed main body side, so even if the front plate is opened and closed vigorously, or the main body is installed diagonally or horizontally. Even when the disc is in use, the mounted disc will not come off and become misaligned. When the playback is completed and the front plate 25 is opened from the main body 24, the operation opposite to the above is performed, and as the clamper 30 is closed, the disk 22 supported on the turntable 28 is switched and supported by the sliding tray 31. and said disk 2
The tray 31 supporting the holder 2 is projected outward from the main body 24. Thereafter, as described above, the disc 22 can be held and removed using the notches 48 and 49 with a fingertip or the like. Further, as described above, when the front plate 25 is in the open state, the disc 22 is placed on the tray 31 with the label surface 22a facing outward, so there is no need to take out the disc and reverse it as in the conventional case. The label display on the label surface 22a can be viewed while placed on the receiving IL 31. Therefore, according to this example, even when the disc 22 is loaded into the disc playback device 21, the disc 22
In the same way as when storing the disc into the disc case 23, the disc can be mounted while facing the label display on the label surface 22a. In other words, there is no need for the conventional reversing operation, which eliminates complicated work. By eliminating the reversing operation, it is possible to avoid contaminating the disc, and it is possible to prevent deterioration of sound quality and occurrence of information reading errors. In addition, the disk 22 is mounted on a saucer 31 provided on the main body side.
After the disc 22 is mounted, the label surface 22a of the disc 22 faces outward. Therefore, the label display on the label surface 22a can be confirmed without removing the disc 22. Furthermore, since the disc 22 is placed on a tray 31 that is positioned in advance and slides on the turntable 28,
Positioning of the disk 22 during installation is easily performed. In addition, since the disc 22 is mounted on a tray that is provided on the fixed main body side rather than on the front plate side that can be opened and closed, even if the disc playback device is installed at an angle, Even when the face plate 25 is vigorously opened and closed, the disc will not come off and the disc will not be misaligned. Moreover, the observance M material for interlocking and sliding the front plate 25 and the saucer 31 is III! Since this is performed based on the rotational drive of the oil damper 43, the number of parts is small, smooth operation can be realized, and the commercial value is high. Effects of the Invention According to the present invention, the disk-shaped recording medium can be attached to the main body by M.
Since this is done by placing the disk-shaped recording medium on a movable tray, it can be loaded with the labeled surface facing outward, and there is no need to flip the disk-shaped recording medium. By deleting operations, it is also possible to prevent contamination of the disc, thereby avoiding deterioration in sound quality and errors in reading information. In addition, when the front ILY board is open, the surface with the label of the disc-shaped recording medium can be exposed to the outside, so the label can be checked without having to take out the disc-shaped recording medium. . Furthermore, since the disk-shaped recording medium is mounted by being placed on a sliding tray that is positioned in advance with respect to the turntable, the center of the disk-shaped recording medium can be easily positioned. Furthermore, since the disk-shaped recording medium is not placed on the front plate side that can be opened and closed, but on the tray provided on the fixed main body side, there are cases where the two main bodies are installed at an angle or horizontally, or when the front plate is installed. Even if the device is opened and closed with great force, the installed disk-shaped recording medium will not be misaligned. Furthermore, since the sliding movement between the front plate and the saucer is performed by interlocking members, smooth movement can be achieved with a small number of parts, and the product value is high.
