[0025]
Next, when the optical disk recording / reproducing apparatus 30 in the reproduction mode finishes the reproduction and ejects the optical disk 20 to the outside, the optical disk 20 is guided by the disk guide claw 70 and the first locking claw 50 and the The operation of being securely locked by the second locking claw portion 60 will be described.
[0026]
FIGS. 7A to 7G show the peripheral edge 20a of the optical disc 20 in the reproduction mode state, the first locking claw 50, the second locking claw 60, and the disc guide claw in FIGS. It shows the positional relationship with 70. FIGS. 7D and 7G are enlarged views of the position of the optical disk peripheral edge 20a with respect to the first locking claw 50. FIG. FIGS. 7B and 7E show an enlarged view of the position of the optical disk peripheral edge 20a with respect to the second locking claw portion 60. FIG. FIGS. 7C and 7F are enlarged views of the position of the optical disk peripheral edge 20a with respect to the disk guide claw 70. FIG. FIGS. 7H, 7I, and 7J show the state when the reproduction of the optical disk 20 is completed and the operation of releasing the clamp of the optical disk 20 is started. FIGS. 8A to 8J are views corresponding to FIGS. 7A to 7J in a state where the optical disc 20 shown in FIG. 2B is released from the clamp. FIGS. 9A to 9G show the above-described FIGS. 7A to 7G in a state where the optical disk 20 shown in FIG. 2C is carried out of the apparatus main body 31 by the disk tray 40. FIG.
[0027]
In the reproduction mode in which the optical disk 20 is clamped on the turntable 33, the optical disk 20 is floating above the bottom surface of the disk mounting portion 41 as shown in FIGS. Also, as shown in FIGS. 7A, 7D, and 7B, the optical disc 20 is located between the peripheral edge 20a and the first locking claw 50 and the second locking claw 60. As viewed in the radial direction, there is an equal gap g1. In the Y1-Y2 direction, there is a gap g2 between the peripheral edge 20a and the first locking claw 50, and a gap between the peripheral edge 20a and the second locking claw 60. g3 is open. Due to the arrangement of the first locking claw 50 and the second locking claw 60, the gap g3 is always larger than the gap g2. Therefore, when the optical disc 20 is displaced in the Y2 direction, the start of the locking to the second locking claw portion 60 is always delayed compared to the start of the locking to the first locking claw portion 50. . This is the reason why the operation of locking the optical disk 20 to the second locking claw portion 60 becomes unstable.
[0028]
The disk guide claw 70, which is a main part of the present invention, located near the second locking claw 60 has a gap between the disk guide claw 70 and the peripheral edge 20a. The gap g4 is equal to the gap g1 described above, and in the Y1-Y2 direction, the gap g5 is determined to be equal to the gap g2 of the first locking claw 50. That is, g5 = g2 and g5 <g3.
[0029]
When the operation of releasing the clamp of the optical disk 20 is started after the reproduction of the optical disk 20 is completed, the optical disk 20 is displaced only in the Z1 direction without being displaced in the Y2 direction, and FIG. 7 (E), (F), The state shown in FIG. 7G is the state shown in FIGS. 7H, 7I, and 7J, respectively.
[0030]
When the clamp of the optical disk 20 is released as shown in FIG. 2B, the optical disk 20 slightly moves in the Y2 direction by gravity inside the disk mounting portion 41 as shown in FIG. The gaps g2, g3, and g4 are reduced, and the end of the peripheral edge 20a in the Y2 direction is supported by the disc centering guide portion 38 at the notch opening 44.
[0031]
As shown in FIGS. 8D and 8G, the gap between the peripheral edge 20a and the first locking claw 50 becomes zero. As shown in FIGS. 8B and 8E, a gap g6 still remains between the peripheral edge 20a and the second locking claw portion 60. As shown in FIGS. 8C and 8F, the gap between the peripheral edge 20a and the disc guide claw 70 is zero.
[0032]
When the disc tray 40 starts moving in the X2 direction and the optical disc 20 starts to be disengaged from the disc centering guide portion 37, the optical disc 20 starts displacing with respect to the disc tray 40 in the Y2 direction, as shown in FIG. The peripheral edge 20a is guided by the inclined surface 50a and starts to be locked by the first locking claw portion 50, and as shown in FIG. 8 (I), the peripheral edge 20a is moved along the inclined surface 70a. When the disk tray 40 which starts to be guided by 70 moves in the X2 direction, the disk mounting portion 41 goes out of the device main body 31 and the optical disk 20 is carried out of the device main body 31, the optical disk 20 is moved to the disk centering guide portion 38. Completely displaced in the Y2 direction.
[0033]
Regarding the first locking claw portion 50, since the peripheral edge 20a has begun to be guided on the inclined surface 50a, as shown in FIGS. 9A, 9D, and 9G, the peripheral edge 20a is in the first engagement position. The pawl 50 is normally and completely locked.
[0034]
Regarding the disc guide claws 70, the peripheral edge 20a has begun to be guided by the inclined surface 70a, and as shown in FIGS. 9A, 9C, and 9F, the peripheral edge 20a of the optical disc 20 is It is completely guided by the claws 70.
[0035]
Regarding the second locking claw 60 located near the disc guide claw 70, the direction in which the optical disc 20 is pulled out of the disc mounting portion 41 by the peripheral edge 20 a of the optical disc 20 being guided by the disc guide claw 70. That is, by restricting unnecessary displacement in the Z2 direction, the peripheral edge 20a of the optical disc 20 starts to be reliably locked by the second locking claw portion 60, and FIGS. 9A and 9B , (E) is securely locked completely.
[0036]
Therefore, when the computer device placed on the table is vertical and the optical disc recording / reproducing device 30 is in a vertical position, as shown in FIG. Even if the optical disk recording / reproducing apparatus 30 is slightly overhanged as shown in FIG. 10, the disk tray 40 moves in the X2 direction and the optical disk 20 is carried out of the apparatus main body 31. In this state, the optical disk 20 is located in the disk mounting portion 41, and the peripheral edge 20a on the Y2 side is normally locked by the first locking claw portion 50 and the second locking claw portion 60. The disk guide claw 70 is also locked by the disk guide claw 70, and does not fall off the disk tray as shown in FIG. Sukutorei 40 continue to be supported on.
[0037]
As shown in FIG. 2C, a plurality of opening windows 45 are formed in a portion near the X1 side of the disc tray 40 for weight reduction.
[0038]
Ribs 50b, 60b, 70b are formed above the first locking claw 50, the second locking claw 60, and the disc guide claw 70. The ribs 50b, 60b, and 70b are located in a gap between the disc tray 40 and the ceiling surface of the apparatus main body 31, and the optical disc unclamped in a state where the disc tray 40 is inside the apparatus main body 31. The optical disk 20 moves in the Z2 direction for some reason and floats from the disk mounting portion 41, and the optical disk 20 moves the first locking claw 50 or the second locking claw 60 and the Z2 side of the disk guide claw 70. The movement of the optical disk 20 is restricted when the user tries to get over the disk. This prevents the optical disk 20 from rolling out of the disk mounting portion 41 into the apparatus main body 31.
[0039]
In the present embodiment, a rack (not shown) that engages with the pinion of the disk tray moving mechanism 35 is formed continuously on the back surface of the disk tray 40 of the disk tray 40, and this rack (not shown) is broken. However, the disc guide claw and the disc guide claw are arranged symmetrically with respect to each other, so that the disc guide claw is formed separately from the second disc lock claw. If a rack (not shown) is not formed on the rear surface of the second disk engaging claw, the disk guide claw extends from the second disk engaging claw toward the cutout openings 44 and 44A. It is also possible to form continuously.
[0040]
As shown in FIG. 1, the first locking claw portions 50 and 50A, the second locking claw portions 60 and 60A, and the disc guide claw portions 70 and 70A Since the optical disk recording / reproducing device 30 is symmetrically arranged in the −Y2 direction, the optical disk recording / reproducing device 30 can be installed in a direction in which the disk centering guide portion 39 is located on the lower side. In this case, the optical disc 20 is guided by the disc guide claws 70A, whereby the optical disc 20 is normally locked to the second locking claws 60A.
[0041]
The optical disk recording / reproducing apparatus 30 can be used with the disk tray 40 installed in a horizontal state.
[0042]
In addition, the above-mentioned optical disc 20 refers to all optical discs used as information recording media such as CD-ROM, CD-R, CD ± RW, DVD-ROM, DVD-R, DVD ± RW, DVD-RAM, etc. Needless to say, the disc tray 40 having the above structure can be used in all optical disc recording and / or reproducing apparatuses for recording and / or reproducing on and from the optical disc 20.
[0043]
【The invention's effect】
As described above, the present invention relates to a disk device including a disk tray having a disk locking claw for locking a lower edge of a disk in a vertical position so that the disk does not fall down. Since the tray has a disk guide portion for guiding the disk so that the edge of the disk is locked by the disk locking claw portion, the disk is carried out of the disk device body by the disk tray. Sometimes, the operation of locking the disk to the disk locking claw portion can be performed more reliably than in the past, so that even if the disk device is slightly overhanging, the disk can be locked. It is possible to prevent spilling from the tray and improve reliability.
