Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a disk storage device for storing a disk used in a recording/reproducing device for recording or reproducing information or a reproducing device for reproducing information.

Conventional configurations and their problems In recent years, there are playback-only devices or recording/playback devices that use disks as a means to file video information and document information and to search each piece of information at high speed. Generally, a single disk is manually converted and installed, and the amount of information that can be processed at one time is limited. On the other hand, an information processing system capable of storing large amounts of information and performing high-speed searches is desired in various fields. To do this, it is necessary to store multiple disks, automatically replace any desired disk at high speed, and attach it to a player such as an optical recording/playback device that plays or records/plays information, and plays the desired information. , or an automatic disk changer (hereinafter referred to as an autochanger) for recording is required.
Additionally, there is a need for a disk jacket that can be applied to the autochanger described above.

Conventionally, such disk jackets include a jacket type that houses a disk inside a video disk jacket, and one that allows the disk to be inserted along with the jacket onto the player's turntable manually without touching the disk directly. However, in order to mount the disc on the turntable, it is necessary to remove only the jacket. Furthermore, when taking out a disc, an empty jacket must be inserted again, which not only requires more time than necessary to mount or unmount the disc on the turntable, but also makes the disc mounting mechanism complicated and expensive. I become confused. Furthermore, since the disk and jacket are a pair, even if the recorded contents of the disk stored in the jacket become outdated or the disk is damaged due to equipment malfunction, it is extremely troublesome to replace it with a new disk. However, it is not possible to easily store any disk in the jacket.

Therefore, it is insufficient for use in an autochanger that has a large capacity and searches for desired information at high speed.

Purpose of the invention In view of the above-mentioned conventional problems, the present invention selects a desired disk jacket from a plurality of disk jackets containing disks and automatically records it on the disk or records the information on the disk. The present invention relates to a disk storage device that can be applied to an autochanger that reproduces information, and provides a disk storage device that can be smoothly stored in a storage section for storing a disk jacket.

Composition of the Invention The present invention comprises a disk jacket having a disk storage part for rotatably storing a disk therein, an engaging part for drawing out the main body on the front surface substantially perpendicular to the drawing direction, and a plurality of disk jackets. and a storage housing having a pair of concave grooves for storing each disk jacket parallel to the pull-out direction, and the disk jacket has a pair of concave grooves for storing the disk jacket parallel to the pull-out direction. A sliding portion is provided for guiding the insertion into the disc, and the tip of the sliding portion in the thickness direction of the disk on the side to be inserted into at least one pair of grooves is wedge-shaped, and the height of the sliding portion is set lower than the height of the groove. By making it larger, even if the insertion position into the groove is slightly shifted, it can be smoothly inserted and guided into the groove.

Also, since the title and information content of the disc will change due to disc replacement, the display label 21 is removed and a new display label 21' is pasted. Therefore, to exchange the disk 1 housed inside the disk jacket 7 with any disk 1', the insertion/removal portion 13 provided on the outer side of the disk jacket 7 is rotated in the direction of arrow c. You can easily do it by just doing this.

Next, the schematic configuration of the autochanger applied to the disk storage device of the present invention is shown in FIGS. 11 and 12.
This will be explained using figures. Reference numeral 28 denotes a storage section constituting a storage case, in which a plurality of disk jackets 7 are stored. Reference numeral 29 denotes a movable board equipped with a pull-out mechanism 30 for pulling out the disk jacket 7 in the direction of arrow a, and a clamper 31 for clamping the disk 1, and is movable in the direction of arrow e by an external moving means (not shown). Retained. 31
is a player base, which has a turntable 33 that fits into the engagement hole 2 of the disk 1, a motor 32 that rotates the disk 1, and a signal recording/reproducing device that records information on the disk 1 or reproduces recorded information. An optical head 34 for use with the player, a transfer means 35 for transferring the optical head 34 in the radial direction of the disk 1, and a positioning pin 36 and a positioning post 37 for positioning the disk jacket 7 on the player base 31 are mounted. ing.

The storage state of the disk jacket and its operation in the autochanger constructed as above will be explained with reference to FIGS. 8 to 10. In FIG. 8, reference numeral 28 denotes a storage section that stores a plurality of disk jackets 7. Normally, the disk jackets 7 are stored between the upper groove 38 and the lower groove 39 of the storage section 28, and are positioned in the direction of arrow e. ing. Also, the storage section 28 of the disk jacket 7
Positioning in the direction of the arrow a is performed using the positioning member 4.
This is done by 0. The positioning member 40 is a roller 4 supported by an elastic member 41 such as a leaf spring.
2, which engages with the positioning groove 11 of the disk jacket 7 to position and hold the disk jacket 7 within the storage portion 28. A through hole 43 is provided in the lower groove 39 of the storage portion 28, and the light x emitted from the disk jacket presence/absence detecting means consisting of a photodetector 44 detects the presence or absence of the disk jacket in the disk jacket 7. The reflected light x' is reflected by the reflecting plate 26 of the detecting section 18 and is again received by the disk jacket presence/absence detecting means 44.

Although the disk jacket presence/absence detection means 44 is not shown, it is installed on the movable board 29, and as the movable board 29 moves, it moves in the direction of the arrow e.
For example, if the disk jacket 7 is not stored at a certain position in the storage section 28, the light x emitted by the disk jacket presence/absence detection means 44 passes through the through hole 43. However, since there is no disk jacket 7,
The irradiated light x continues straight. Therefore, since no light returns to the disk jacket detection means 44, the disk jacket detection means 44 determines that the disk jacket 7 is not stored. However, when the disk jacket 7 is stored in a predetermined position, the light x emitted from the disk jacket presence/absence detection means 44 is transmitted to the disk jacket presence/absence detection section 1 of the disk jacket 7.
The reflected light x' is reflected by the reflector 26 of No. 8, and is received by the disk jacket presence/absence detection means 44. It is determined that it is stored.

The drawer portion 30a of the drawer mechanism 30 that moves the disk jacket 7 in the direction of arrow a, the engaging portion 12 of the disk jacket 7, and the drawer portion 3
0a and the side portion 45 of the disk jacket 7 are separated by a small space. Reference numeral 46 designates a pull-out guide rail that guides the disk jacket 7 when the disk jacket 7 is moved in the direction of arrow a by the pull-out mechanism 30. It is composed of At this time, since both ends of the sliding parts 19 and 20 of the disk jacket 7 are each formed into a wedge shape, the grooves 38 and 39 of the storage part 28
Even if the drawer guide rail 46 is slightly deviated in the direction of the arrow e, the disk jacket 7 will not collide with the drawer guide rail 46 or the grooves 38 and 39 of the storage section 28 and will move in the direction of the arrow a.
You can move smoothly in any direction. Further, the guide rail 46 and the groove 38 of the storage section 28,
It goes without saying that the effect will be even better if the end shape of 39 is formed into a reverse wedge shape. Therefore, even if the grooves 38, 39 of the storage section 28 and the drawer guide rail 46 are slightly misaligned in the direction of the arrow e, the disk jacket 7 can be moved in the direction of the arrow a, which will be described later. However, the mechanism for positioning the movable board 29 in the direction of the arrow e when searching for a desired disk jacket 7 can be made simple.

Next, the search for the disk jacket 7 will be explained. When attempting to search for the disk jacket 7 that houses the disk 1 containing the desired information,
The moving board 29 moves in the direction of arrow e, and the corresponding disk jacket 7 is moved to a position facing the pull-out mechanism 30. At this time, the plurality of disk jackets 7 stored in the storage section 28 are
Since the drawer portion 30a is positioned and held within the storage portion 28 by the positioning member 40, the drawer portion 30a does not come into contact with the side portion 45 of the disk jacket 7 and the engaging portion 12. When the drawer mechanism 30 mounted on the movable board 29 is moved to the desired position of the disk jacket 7, the disk jacket presence/absence detecting means 44 detects the position of the disk jacket 7.
The presence or absence of is confirmed. If the disk jacket 7 is present, the pull-out mechanism 30 begins to be moved in the direction of arrow a' by disk jacket pull-out means (not shown). At the same time, the drawer section 30a
comes into contact with the engaging portion 12 of the disk jacket 7, and as the drawer portion 30a moves, the disk jacket 7 is moved to a position facing the turntable 33 shown in FIG. 11 in the direction of arrow a'. . Although not shown, the disk jacket 7 is positioned and held on the drawer guide rail 46 by a positioning member, which is the same as the positioning member 40, provided on the upper drawer guide rail 46. While the disk jacket 7 is positioned and held on the drawer guide rail 46, the disk jacket 7 is moved by a moving means (not shown) for the moving board 29.
As shown in FIG. 12, the protruding portions 36b of the 36 positioning pins protruding from the player base 31 fit into the position regulating holes 17a, 17b of the disc jacket 7. The disc jacket 7 is positioned on the player base 31. The protruding portion 36b of the positioning pin 36 has a tapered tip so that it can be easily inserted into the position regulating holes 17a, 17b. Further, the position of the disk jacket 7 is also regulated in the direction of arrow e' by the end 36a of the positioning pin 36 and the end 37a of the positioning post 37.

On the other hand, the disk 1 housed in the disk jacket 7 is placed on the turntable 33 with the disk positioning member 33a protruding from the turntable 33 engaging with the engagement hole 2 of the disk 1. At the same time, the clamper 31 operates in the direction of arrow e', enters the second opening 9 of the disk jacket 7, and moves the disk 1 onto the turntable 33.
By pressing in the direction of , the disk 1 is held fixed. At this time, the disk 1 is positioned with a gap 25 between the disk protection member 23a provided inside the second opening 9 of the disk jacket 7, and
The moving means of the movable base plate 29 and the clamper 31 are arranged so that the movable base plate 29 can be rotated within the movable base plate 5 without coming into contact with the disk protection member 23a of the disk jacket 7.
Disk 1 is mounted. Thereafter, the motor 32 rotates, the optical head 34 is transported in the radial direction of the disk 1 by the transport means 35, and the desired information is reproduced. When the reproduction of the desired information is finished and the second information held on another disk is to be searched, the disk 1 is released from being fixed by the clamper 31 as the motor 32 stops, and becomes free inside the disk jacket 7. Thereafter, the disk jacket 7 is moved in the direction of the arrow e'' and returned to the predetermined position (the position where the disk jacket 7 is pulled out from the storage section 28).The disk jacket presence detection means 44 moves the disk to the predetermined storage position. Once it is confirmed that the jacket is missing,
The drawer mechanism 30 begins to move in the direction of arrow a'',
The drawer portion 30a of the drawer mechanism 30 comes into contact with the side portion 45 of the disk jacket 7, and moves the disk jacket 7. The disk jacket 7 slides on the drawer guide rail 46 and is further inserted into the storage section 28. The movement of the pull-out mechanism 30 stops at the position shown in FIG. 10, but at this time the roller 42 has slightly entered the positioning groove 11 of the disk jacket 7, and the roller 42 is rotated by the biasing force of the elastic member 41. At the same time, the disk jacket 7 moves slightly in the direction of the arrow a'', and the positioning groove 11 and the roller 42 engage with each other.Therefore, the disk jacket 7 is positioned and held at the position shown in FIG. It is.

As described above, according to this embodiment, a plurality of disk jackets 7 and the engaging portions 12 that engage with the drawer portion 30a provided in the device are stored in the disk jacket 7 that rotatably houses the disk 1. By providing the positioning groove 11 that engages with the positioning member 40 in the storage section 28, when an arbitrary disk jacket 7 is pulled out from the storage section 28, the engagement section 12 can be engaged with the pull-out section 30a. ,
The drawer part 30a can be moved without coming into contact with other disk jackets,
Further, the presence or absence of the disk jacket 7 can be detected by the disk jacket presence/absence detection section 18.
Furthermore, the disc jacket 7 can be automatically pulled out by engaging the engaging part 12 with the pull-out part 30a, and the disc jacket 7 can be reliably positioned on the player base 31 by the position regulating holes 17a and 17b. With the disk 1 housed in the disk jacket 7, recording and reproduction can be performed without the disk 1 coming into contact with the inner wall of the disk jacket 7. Further, disk protection members 23a and 23b are provided inside the disk jacket 7, which can reduce the impact of the disk 1 within the disk jacket 7 when the disk jacket 7 is moved. Even if the disk 1 is accidentally damaged, or if the disk 1 needs to be replaced with an arbitrary disk that has new information, it can be easily replaced by simply rotating the insertion/removal section manually. Moreover, the sliding part 1 of the disk jacket 7
By configuring both ends of 9 and 20 in a wedge shape,
The disk jacket 7 can be easily pulled out. Therefore, it can be fully applied to an autochanger that changes disks at high speed.

According to the embodiment described above, the disk jacket presence/absence detection section 18 was provided on the inclined surface 20a of the sliding section 20 of the disk jacket 7, but due to the configuration with the disk jacket presence/absence detection means 44, It may be provided at any position on the outer side of 7. Further, the disk jacket presence/absence detection section 18 may be used for positioning the disk jacket 7 when it is pulled out.

Effects of the invention As described above, according to the invention, the disc jacket is provided with a sliding part for guiding insertion into a pair of concave grooves, and at least the disc on the side to be inserted into the pair of grooves is The shape of the tip of the sliding part in the plate thickness direction is wedge-shaped, and the height of the sliding part is larger than the height of the groove, so even if the insertion position into the groove is slightly misaligned, it will not fit inside the groove. The insertion can be guided smoothly. In other words, when storing a disk jacket in a pair of grooves, even if the disk jacket is moved with the grooves and guide rails slightly misaligned, the sliding portion will insert and guide the disk jacket into each groove. Not only can the insertion operation be performed smoothly, but the groove width can be kept to just the width needed to move the disk jacket, making it easy to downsize the storage case to meet the required capacity. It also has the effect that
