It is rotated at a variable rotational speed of m, and is reproduced by linear tracking from the inner circumferential side to the outer circumferential side using an optical pickup containing a semiconductor laser and a photoelectric conversion element.

In this case, CDs have a huge amount of information recorded on each side, allowing for approximately one hour of stereo playback, and have a higher recording density than conventional analog discs in terms of playback characteristics. It has been established in principle that it can be made significantly superior in terms of.

By the way, as a way to utilize the excellent features of such CDs, it is being considered that they can be used, for example, in multi-disc automatic performance devices for professional use.

In other words, this corresponds to a so-called jukebox or karaoke device which is also put into practical use with analog discs, and can be realized by a disc autochanger device.

However, this type of disc autochanger device, which has been known for a long time, has a complex structure and large size because it is intended for analog discs, and therefore has problems in terms of operability. Ta.

In addition, due to the need for reliable operation, the number of discs stored cannot be increased that much, and the exchange rate of one disc cannot be made that fast.

Therefore, there are many problems in applying the conventional disc autochanger device for CDs as described above, and it is an urgent issue to develop a disc autochanger device suitable for CDs. It had been.

Incidentally, this situation is the same in the case of a radar video disc, and also in the case of application to an optical disc file system that has recently been put into practical use as a part of so-called electronic file conversion.

Therefore, the present invention has been made in view of the above points, and it is possible to increase the number of discs stored with as little space as possible, and to easily display the number of disc storage groove positions. The object of the present invention is to provide an improved and extremely good disc autochanger device.

[Summary of the invention]

That is, in order to achieve the above object, the disc autochanger device according to the present invention is a disc autochanger device that automatically searches a large number of discs stored in a tray and can exchange and supply a predetermined disc to a disc playing section. , the tray has a trough that serves as a disk storage groove formed in an approximately 1/4 semicircular shape and is connected only to one side of the trough, allowing the disk to be exchanged and supplied to be stored vertically. It is formed by laminating and integrating a large number of tray leaves that have partition walls and are divided and formed for each disk storage groove unit, and each of the tray leaves has a thin wall that can be easily removed by external force at the rear upper end of each partition wall. It is characterized by a continuous guide piece for indicating the position of the disc storage groove.

[Embodiments of the invention]

First, as a basic example of the present invention, a case where the present invention is applied to a multi-disc automatic performance apparatus for CDs will be explained in detail with reference to the drawings.

FIG. 1 shows a front external view of a cabinet 100 that houses a disc autochanger mechanism, which will be described later. 101 is a main tray storage area that can accommodate a large number of discs (60 discs in this case), and 102 is a small number of discs. This is an auxiliary tray storage section that serves as a plus-one tray to allow one disk (in this case, one) to be freely inserted and removed.

Further, 103 is an operation section for specifying performance status such as start, pause, cancellation of performance, redo, etc., 104 is a key operation section and its display section that allows reservation of up to 5 songs in this case, and 105
106 is a display section for song pitch (tempo) control and key control; 107 is a display section for signal level;
108 is a display section for the song currently being played, and 109 is a display section for the next song to be played.

Note that 110 is a headphone plug insertion part, 111 is a small insertion part for a remote control plug, and 112 is an operation part for inserting and removing the auxiliary tray.

FIGS. 2 and 3 show a perspective view and a plan view of the disc autochanger mechanism taken out from the cabinet 100 shown in FIG. It has a main tray mechanism section 200, an auxiliary tray mechanism section 300, and a disc search performance mechanism section 400, which are mounted in a similar relationship.

To roughly explain the operation of such an autochanger mechanism, a predetermined number of disks 201 are stored in advance in a disk storage QIj 203 of a tray body 202, which will be described later, in the raw tray mechanism section 200 (or With respect to the auxiliary tray mechanism section 300), first, the disk search performance mechanism section 400 searches for the target disk 201 and takes out the disk 201 by moving in the directions of arrows A and B in the figure based on the disk access information. Then, after playing the disc 201, move it to the main tray mechanism section 2.
00 or the original position on the auxiliary tray mechanism section 300, the same operation as described above is repeated based on the next disk access information.

In this case, the main tray mechanism Q 20 (7 is a tray body 202 made of synthetic resin that is detachably supported on left and right tray support stands 253 and 254 erected on the main chassis 121 as described later). has been done.

In addition, the auxiliary tray mechanism section 300 has its auxiliary tray 301
is supported by an auxiliary tray drive nM350, which will be described later, so that it can move in and out in the directions of arrows C and D in the figure.

Further, the disc search performance mechanism section 400 includes a disc search section 500 and a disc transport mechanism section 60, which will be described later.
0 and the disc performance mechanism section 700 are integrated into a unit, and the main chassis 12
It is moved in the directions of arrows A and B in the figure by the driving force of a search wire 403, which will be described later, using a rail 401 and a guide shaft 402 supported by 1 as guides.

In addition, 404 in FIG. 3 is a synthetic resin address plate supported on the main chassis 121, and is formed in the tray body 202 of the main tray mechanism section 200, in this case 60 disk storage grooves 203. Four turns (based on a binary system that allows optical detection of absolute addresses in one-to-one correspondence) are formed. However, the support structure for the address plate 404 with respect to the main chassis 121 will be described later.

Next, the details of each of the above parts will be explained in order.

FIG. 4 (IL) shows the main tray mechanism section 200 taken out from above, and includes a tray main body 202 having 60 disk storage grooves 203 of approximately 1/4 semicircular shape, and A U-shaped disc hold lever 205 rotatably supported via a spring 204 between both sides of the disc, an attachment/detachment guide part 206 similarly formed on both sides, and corresponding to each entrance/exit part of the disc storage 1ll 1203. It has 60 positioning slits 207 formed as shown in FIG.

Figure 5 (a), (b)? (e) is a cross-sectional side view, a side view, and a front view showing details of the tray main body 202, each with a valley having a radius of curvature R1 suitable for the disk 201 to be stored, and a peak having a predetermined shape as described later. 60 disk storage #203 each having a partition of a predetermined height of 920 g and approximately 1/4 semicircular shape are arranged at a predetermined pitch in the longitudinal direction (in the case shown, in 4 orders for 1.2 nm thick CDs). However, the valley width at the entrance part is 1.4 m, and the valley width at the deep part is 2.8 meters wide at the end), and the valley disk storage groove 203 has a continuous shape. A cutout portion 209 and a locking portion 210 are formed in the pot bottom '815, and the aforementioned slits 207 are formed in each entrance and exit portion.

Here, the partition wall 208 of the disk storage groove 203 is designed to prevent each part of the disk 201 in the storage direction from hitting the top of the partition wall 2080 when the disk 201 is stored. The height is set.

In other words, the disk 20 is stored in sliding contact with the bottom of the groove in the direction of the arrow E in the figure, but if no consideration is given to the height of the partition wall 208, the disk will be stored in the disk storage groove 203. When the disk 201 is tilted in a direction perpendicular to the storage direction, the tip of the disk 201 comes into contact with the top of the partition wall 208 at that position.

Therefore, the top of each part of the partition wall 208 is connected to the disk 2.
If it is set to have a radius of curvature larger than that of the disk 201, in other words, it is located on a line that slopes outward from the tangent Q of the disk outer circumferential circle P at each position in the storage direction of disk 201. The disk 201 can be smoothly stored without causing the above-mentioned problems.

In FIG. 4, reference numeral 209 indicates a notch for pushing up the disk, which is formed in connection with the bottom of each of the disk storage grooves 203, and 210 indicates a notch for locking the tray body, which is formed on one side of the notch 209. This is a step-shaped locking portion, and the details thereof will be described later.

Further, 270 is a drawer section which will be described later.

FIG. 6 is an exploded perspective view illustrating the procedure for attaching and detaching the main tray mechanism section 200 as described above. When attached, the main tray mechanism section 200 is installed on the pair of left and right tray supports 253 and 254. On the other hand, the tray body 202
It is sufficient to insert the attachment/detachment guide portions 206 formed on both sides in the direction of arrow F in the figure.

However, in this case, before insertion, the disk hold lever 205 is in the position shown by the solid line, rotated in the direction of the arrow G by the biasing force of the spring 204, and any of the disks 201 may inadvertently fall off from the tray body 202. It is commonly possible to prevent this from happening.

During the insertion process in the direction of the arrow F, the disk hold lever 205 has both end locking portions 257 connected to the lock pins 258 provided on the tray supports 253 and 254.
259 to the position shown by the chain line in the illustration.
direction, and is locked at the final position in the insertion direction.

FIG. 7 is a progress diagram for explaining such an insertion (locked) state, and (a) shows that the locking portion 257 of the disc holder Leno 4-205 is inserted into the lock pin 258 during the insertion process in the direction of the arrow F. It is in contact with 259. (b) shows a state in which the locking portion 257 passes between the lock pins 258 and 259 by further insertion, and the disc holder renocou 205 is rotated in the direction of arrow H in the figure. When (C) is further inserted, the biasing force of the spring 204 causes the disc hold lever 205 to
The locking portion 257 is engaged with the locking pin 258 and is locked.

When the installation of the main tray mechanism section 200 is completed, the disk hole lever 205 has been rotated to a position corresponding to the chain line in FIG. 6 as shown in FIG. The discs 201 stored in the discs 201 can be selectively taken in and out in nine functions.

Further, when the installation is completed, as shown in FIGS. 6 and 8, the row 2261 is supported at the tip of the tray holding lever 260 provided on the back side of the tray support base 253.
is intruding from the window 253 & the tray body 2
020 The tip of the attachment/detachment guide part 206 has a sedge ring 262
The rollers 265 are pressed in the direction of the arrow shown in the figure by the biasing force of , 266 are the window portions 253b, 2
53c, the corresponding side end of the tray body 202 is pressed in the direction of the arrow J shown in the figure.

As a result, the installation of the main tray mechanism section 200 is completed as shown in FIGS. 2 and 3, and in this installed state, it is fixed without wobbling or the like due to the locking action and pressing action as described above. will be done.

By fixing the main tray mechanism section 200, the tray main body 202 is thermally maintained as shown in FIG.

The left end side is made to be expandable and retractable with the right end side in FIG. 3 as a reference.

In addition, since the address plate 404 needs to be supported in a one-to-one facing relationship with each disk storage groove 203 and slit 207 of the tray body 202, the main chassis 121 must be supported as shown in FIGS. 2 and 8. On the other hand, the board splash 2
68 and a buffer member 269 such as rubber, the right end side is thermally supported so that it can expand and contract with the left end side as a reference.

This allows even if there is a change in ambient temperature,
If the tray body 202 and the address plate 404 are made of materials having the same thermal properties, such as the same type of synthetic resin, each disk storage groove 2 of the tray body 202 can be
03, the slit 207, and the absolute address detection pattern of the address plate 404 are thermally expanded and contracted by the same amount, and a one-to-one relationship is maintained. It is something that has been set up so that it can be done.

When removing the main tray mechanism section 200 from the main body, first place your hand on the disc hold lever 205 located at the solid line position shown in FIGS. 8 and 10 in order to release the stuck state. After pressing the lever 205 slightly downward, the tray body 202 can be pulled out in the direction of the arrow M, which is opposite to the insertion direction, by placing a hand on the drawer part 270 formed at the bottom of the tray body 202.

FIG. 9 is a progress diagram for explaining the state of pulling out and unlocking the disc lever 205.
Immediately after pushing down the lever 205 in the direction of the arrow shown in the figure,
This is a state in which the engagement between the locking portion 257 and the lock pin 258 is released.

(b) shows a state in which when the tray main body 202 is pulled out in the direction of the arrow in the figure, the locking portion 257 of the lever 205 passes between the lock pins 258 and 259, allowing the tray body 202 to be pulled out in the same direction.

When the main tray mechanism 9200 is completely pulled out, the disc hold lever 205 is moved by the spring 2.
Due to the biasing force of 04, the position of the chain line in Fig.
Since the disk 201 will return to the position indicated by the solid line in the figure, the disk 201 will be placed inside the tray main body 201 during and after pulling out.
It is possible to prevent it from accidentally falling off.

In addition, in the process of such a pull-out operation, if the raw tray mechanism unit 200 is made to be able to be pulled out while the disc hold lever 205 is held down in the direction of the arrow shown in the figure, the disc cannot be pulled out when the lever 205 is pulled out. However, in reality, as mentioned above, the locking part 2 of the lever 205 is removed during the drawing process.
51 is engaged with the lock pin 259 as shown in FIG.
Rotation in the G direction is allowed, and as shown in Figure 10, it is before being pushed in! i! The disk returns to the line position, and the disk can be effectively prevented from falling off.

As described above, it becomes possible to stably attach and detach the main tray mechanism t8A200.

By the way, if this continues, there is a risk that the disk 201 may inadvertently fall off from the tray body 202 inside the main body due to external vibration equal pressure applied to the main body while the main tray mechanism 5200 is installed in the main body.

For this purpose, as shown in FIG. 11, a disc stop wire 406 whose both ends are secured to the front end of the disc search center unit 85400 via a spring 405 is attached to a pulley 407 supported by the side chassis 122° 123.
40g and 409, 410 in a loop shape, the disc stop wire 406 is linked to whatever position the disc search performance mechanism section 400 moves in the directions of arrows A and B in the figure. Therefore, in the process shown in FIG. 12, the disk strike/dewire 406 faces any of the disks 201 housed in the tray body 202 of the main tray mechanism section 200 (see FIG. 3). Therefore, it is possible to prevent the disc from accidentally falling out of the main body.

Note that when any disc stored in the main tray mechanism section 200 is searched and played by the disk search performance device el!Is 40' as described later, K is stored in the main tray mechanism section. 200 cannot be taken in or taken out.

FIG. 13 shows the auxiliary tray 300 taken out from the above, and in this case &-1 the auxiliary tray 3
01 is pulled out in the direction of arrow C in the figure.

That is, the auxiliary tray 301 has a front vAK of approximately 1/4 semicircular disk storage m groups 302 that can store the m extra disks 201, and has an auxiliary tray chassis 303 at the tlkw5. The auxiliary tray chassis 5ash is made of synthetic resin or the like, and the auxiliary tray chassis 5ash is arranged vertically near the right side chassis 123, and has sliding bearings 306, 307 and row 2308
The auxiliary tray chassis 303 is supported so as to be slidable in the directions shown by arrows 1:1.I C and D through the
The rack 309 integrally formed on the back side l11 is connected to the auxiliary tray drive unit 5SOVc, which will be described later. It is designed to be able to be taken in and out as it is automatically pulled out and retracted from the main body in response to eye operations.

When the auxiliary tray 301 is pulled out as shown in FIG.
-310 is rotated, the disk 201
It is possible to prevent it from falling off to the rear.

In addition, in FIG. 13, the auxiliary tray 301 has a notch 380 connected to the bottom of the disk storage groove 302 for pushing up the disk, and a step-shaped locking part on one side of the notch 380 for locking the auxiliary tray. 381 are formed, the details of which will be described later.

Note that the disk storage (7) formed on the auxiliary tray 301
The height of each part of the partition wall 382 of 149, 302 is the same as that of the tray body 202 of the main tray mechanism section 200 described above.
It is assumed that the same consideration is given to the partition wall 20g of the disk storage $203 formed in .

Further, the entrance/exit part of the disc storage groove 302 formed in the auxiliary tray 301 (rear part in FIG. 13) is formed at the entrance/exit part of the disc storage groove 203 formed in the tray body 202 of the main tray mechanism section 200 described above. It is assumed that a slit (not shown) similar to the positioning slit 207 is formed.

FIG. 14 shows a detailed view of the auxiliary tray drive mechanism 350, in which the driving force from the motor 351 is transferred from the worm gear 352 to the worm wheel gear 353 to the clutch gear 3.
54→first gear 355→second ear 356→third gear 351→fourth gear 358.
09.

Here, the Kura and Chigya 3 inserted in the power transmission path
54 is for limiting the maximum torque that is finally transmitted to the gusset 309 to prevent undesired jamming between the worm gear 352 and the worm wheel gear 353.

, FIGS. 15(a) and 15(b) show the disk stop lever 310 taken out, and as the motor 35 of the auxiliary tray rocking mechanism 350 rotates, the auxiliary tray 301 is moved as shown in the figure. Assume that the object is pulled in the direction of the arrow.

That is, in this case, before the retracting operation starts, as described above, the disc stop lever 310, which is rotatably supported on the rear side of the auxiliary tray 301, has one end biased by the spring 311VC. By being in contact with the stop and pad 312, the other end is positioned at the rear of the disk storage@Hsox, that is, facing the disk entrance/exit portion.

When the retracting operation is performed, the row 2 supported at one end of the Tedisk stop lever 310
313 comes into sliding contact with the inclination fi+tA of the swash plate cam 314 mounted on the main chassis 121, so that the disc strike and breaker 310 resist the biasing force of the spring 311 and move counterclockwise as shown in the figure. It will be rotated in the direction of arrow N.

Accordingly, when the retracting operation of the disc strike lever 310 is completed, the other end of the disc lever 310 is separated from the rear of the disc storage groove 302 of the auxiliary tray 301 as shown in FIGS. 16(a) and 16(b). Since it is located at a position not facing the disc entrance/exit section, the disc 201 can be taken in and taken out by a disc search performance mechanism section 400, which will be described later.

Even when the auxiliary tray 301 is retracted in this way, the above-mentioned disk strike and f-wire 409
This prevents the disc 201 stored in the disc storage groove 302Vc from accidentally falling out within the main body.

Further, it goes without saying that when the auxiliary tray 301 is pulled out, the path opposite to that described above is followed and the state shown in FIG. 13 is finally reached.

Note that when the disc 201 stored in the auxiliary tray mechanism section 300 is searched and played by the disc search performance mechanism g400 as described later, the auxiliary tray mechanism section 300 The tray 301 cannot be taken in or taken out.

Further, in this case, the disc 201 stored in the auxiliary tray mechanism section 300 is searched and put into the playing state only after the disc search performance wR structure is put into the driving state as described later. If this occurs before or during the retracting operation of the auxiliary tray 301, a malfunction may occur in which the disc 201 stored in the auxiliary tray 30 cannot be searched and the playing state cannot be reached. be.

Therefore, as shown in FIG. 17, the auxiliary tray 30
A priority circuit 370 is provided so that the operation by the auxiliary tray loading/unloading operation section 112 (see FIG. 1) is given priority over the access start designation operation 510B (see FIG. 1) for the disk 20 stored in the storage tray. drive control circuit 37
The configuration is such that a 1VC start signal is supplied. From this K, the auxiliary tray loading/unloading operation section 112 is operated for the first time (
When there is a pull-out operation, the start signal from the access start 1 constant operation unit 103 is not supplied to the drive control circuit 371 from the second (retraction) operation until the time required for retraction. , the operation of the auxiliary tray loading/unloading operation section 112 is prioritized over the operation of the access/start specification operation section 103,
Therefore, the auxiliary tray 30 can be removed without causing the above-mentioned malfunction.
The search operation and performance operation for the disc 201 stored in the disc 1 can be performed reliably.

In other words, in this case, the disc search performance mechanism section 401 must be completely pulled into the predetermined position within the main body by the auxiliary tray drive mechanism 350.
It is designed so that the motor does not become in a driving state.

The auxiliary tray detection switch 372 in FIG. 17 is a microswitch provided, for example, at the rear of the side chassis 123 in FIG. Even if the system is configured to allow the start signal to be received or received by operating the start designating operation section 103, the above-mentioned malfunction can be prevented.

FIG. 18 shows a conceptual diagram of the disc autochanger device as described above, in which each operating section 1 as shown in FIG.
Operation unit 9 including 03, 104, 105° 107, etc.
Based on various operation command signals from the main tray mechanism section 200 or the auxiliary tray mechanism section 300, each mechanism section 350, 400 is driven to a predetermined state via a control circuit 920 made up of a microcomputer or the like. The discs 201 of the discs 201 are automatically replaced and played.

Note that the display section 930 in FIG. 18 displays each display s1 (74v 105 t 106 el 08
, 109, etc.

Next, before explaining the details of the disc search performance mechanism section 400.0, a general description will be given of the overall movement process of the disc 201 during loading and unloading. That is, in FIG. 19, 0. O6 to O6 respectively indicate the locus of the center position during the movement process of the disc 201 being taken out from the tray body 202 and loaded into the disc playing mechanism il 700. During unloading, a nearly reverse trajectory is taken to move the disc 201 to the tray body 2020. be stored in its original position.

In this case, the disc search performance mechanism section 4o.

When searching for a predetermined disk 20) based on the access information, a disk pushing mechanism (to be described later) is first driven to push the disk 201 up to zero. Push it up to the position. Then, this 24122010 peripheral part is the disk transport mechanism m6

Since the disk 201 is moved in the direction indicated by the arrow, the disk 201 is loaded in one direction as indicated by the arrow while rolling clockwise in the figure.

These first and second loading sections 610,
When the disk 201 rolled by the disk 630 passes over the disk loading slot section 651, it is separated by the rollers 61 Z and 631g and reaches a disk storage section, which will be described later, due to its own weight. At this time, the disc 201 is placed in the slot.

A disc detector 652 installed in the measuring section 651 is configured to detect the passage of the disc, and in response to the detection of the passage of the disc, a disc playing mechanism i1d, which will be described later, is activated.
700 is driven, and the disc is played.

In this state, when the disc playing operation of the disc playing mechanism section 700 is completed, the disc moving mechanism 5
600 is reversed and motorized.

Then, the first and second loading sections 610.6
30 moves in the direction of the arrow along a pair of curved guide rails 650, 650 while rotating the valley rollers 611, 631 in the clockwise direction in the figure.
1 is brought into contact with the peripheral edge sVC of the disk 201. As a result,
This disk 201 is rolled counterclockwise in the figure by the rollers 611, 631 as it moves in the direction of the arrows of the first and second loading sections 610, 630, and the above-mentioned loading is performed. Take the opposite trajectory and make it into an arrow! move in the direction. And this disk 20
1 is unloaded to a predetermined position, the first and second loading parts 610 and 630 are stopped, so that the tray body 202 is separated from the rollers 611 and 631, and the tray main body 202 is moved to a predetermined position by its own weight. It is accommodated in a rolling manner up to the position Ol.

Here, FIGS. 20 and 21 show the disk search performance mechanism section 400 before and after loading, respectively. That is, numeral 420 in the figure is a mounting structure having a substantially frame shape, and one end of this mounting structure 420 has a mounting structure that moves in the directions of arrows A and B with respect to the tray main body 202 (see FIG. 2) that constitutes the disk search section SOO. A search wire driving mechanism, which will be described later, and the disk pushing mechanism 510, which pushes up the selected disk 201, are installed.

A disk moving mechanism section 600 is installed on the upper surface of the mounting structure 420 corresponding to the disk pushing up mechanism 510 for loading the pushed up disk 201 and unloading it after the performance is finished.

That is, in the search state of the disc search performance mechanism section 400, the motor 531 constituting the wire drive mechanism 530 is rotationally driven to a predetermined state. Then, since the motor 531 rotationally drives the worm wheel gear 533 via the worm gear 532, the search wire 403 is wound around the pulley portion 534 of the worm wheel gear 533. As a result, this search wire 4
03 is wound around the pulley section 534, a predetermined driving force (biasing force) is generated to move the disc search performance mechanism section 400 in the directions of arrows A and B, and a search for the disc 201 is performed. In this case, the disc search performance mechanism section 400 is attached to the mounting structure 42 as shown in FIG.

The locking portion 521 is released from the locking portion 210 of the notch 209 of the tray body 202 to release the locked state.

Next, the first cam portion 545 of the cam 544 rotates the second brake lever 540 in the counterclockwise direction in the figure.
One end of the first brake lever 539 is spaced apart from the worm wheel gear 533. As a result, the braking portion 535 of the worm wheel gear 533 is separated from the viscoelastic member 537 by the spring force of the spring 536, and the lock is released, and the search for the next disk 201 is performed.

Here, as shown in FIG. 28, when the tray main body 201 is pulled out in the M direction during, for example, a disc play, the disc push-up mechanism 510 is configured such that the locking portion 52 of the push-up lever 517 is pressed against the tray main body 202.

Then, as described above, this disk 201 is stored in a predetermined disk storage groove 203 of the tray body 202 (or auxiliary tray 30) by the disk transfer mechanism section 600.

At this time, the second disk detector 734 and the first
The disc detectors 652 (see FIG. 19) each detect the presence or absence of the disc 20 and its passage, and in response to this detection, each part of the disc search performance mechanism section 400 is brought into a predetermined state for the next operation. controlled.

By the way, the disc autochanger device of the basic example described above has the following problems regarding the tray body that accommodates a large number of discs.

That is, since the tray main body 202 is integrally formed by resin molding, the tray main body 202 is formed integrally with the disk storage @20.
Due to molding technology requirements, each partition wall forming 3 must have 1
．． A punching taper of 5 to 2° must be provided, and the presence of the punching taper not only makes it impossible to increase the height of the partition wall above a certain value, but also causes the disc storage groove pitch to be determined by the punching taper. The problem is that the mold is expensive because it is made of material, and it is disadvantageous to increasing the number of discs that can be stored.

Next, an embodiment of the present invention will be described, which is a further development of the configuration of the basic example described above.

First, to describe the gist of the present invention, the tray main body, which was formed integrally in the basic example, is made into a structure in which parts are formed separately for each disc storage groove unit and then stacked. This arrangement is advantageous both in terms of mold price and in increasing the number of discs that can be stored. In other words, the present invention is characterized in that, by dividing each disc storage groove unit in advance, there is no need to provide a punching hole /'P unlike in the case of integral formation.

That is, as shown in FIG. 37, instead of the tray main body 202 shown in FIG.
03A and a partition wall 208k connected only to one side of the valley, the tray leaf 202A is formed separately for each disc storage groove unit, and a large number of these tray leaves 202A are stacked. The three through-holes 202B are tightened with bolts (not shown), and an adhesive is poured between the holes as necessary to form an integrated tray body 202C.

In this case, when stacking each tray leaf 202A, a disk storage groove is formed between the partition walls 208 of the adjacent tray leaves 202, and at this time, the disks stored in the disk storage groove are In order to prevent rattling, each partition wall 208A is provided with an elastic protrusion 202D so that the disk can be stored and held in a state where it is pressed against one of the partition walls 208A.

Note that the disk surface pressed by the elastic protrusion 202D is usually coated with an ultraviolet curable film on the surface opposite to the signal surface, so there is no problem in terms of strength (hardness), and there will be no damage caused by pressing. There is little concern that this will occur. Also, a partition wall 208A against which the signal surface of the disk is pressed
The inner surface of is a conical Qchi)J? By forming a very small amount of the disc, the disc comes into contact with only the outer peripheral edge of the disc, thereby making it possible to prevent scratches on the signal surface of the disc.

Furthermore, each tray leaf 202A is provided with a guide piece 302E having a thin wall that can be easily detached by external force in order to conveniently display the number of disc storage groove positions when stacking and integrating, for example, every 10 discs. It is formed at the rear upper end of the partition wall 208. That is, each tray leaf 2
As soon as 02k is integrated, this guide piece 2 is necessary.
02E is removed every predetermined number of intervals, it becomes possible to easily know the number of disk storage groove positions without providing any other disk storage groove position display member or the like.

As mentioned above, according to the tray main body structure that uses 202 tray leaves that are separately formed for each disk storage groove unit, the extraction chip is different from that of the basic example in which the tray leaves are formed integrally from the beginning. Since there is essentially no need to provide one, not only can the partition wall 208A be made high to ensure stability in storage and retention, but also the pitch of the disk storage groove can be made as narrow as possible, for example, to the limit pitch of the basic example. 3.8m can be extended to about 2.4+m+, making it possible to increase the number of discs stored in a tray of the same size by about 1.6 times, and furthermore reduce the cost of the mold by about 60cm. Can be done.

Further, the disk is separated from the partition wall 20 by the elastic protrusion 202E.
Since it is pressed to 8k, the true pitch of the disc is stabilized and the disc is stably attached to and removed from the tray.This also absorbs and ignores the disc tilt due to variations in disc thickness, which further stabilizes the disc. encouraged.

〔Effect of the invention〕

Therefore, as described in detail above, according to the present invention, it is possible to increase the number of discs stored with as little volume as possible, and the number of disc storage groove positions can be easily displayed. It is possible to provide a disc autochanger device.
