Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a disc autochanger device suitable for, for example, a CD (optical compact disc).

[Technical background of the invention and its problems]

Recently, in the field of audio equipment, a DAD (digital audio disc) reproducing device using PCM (pulse code modulation) technology has been developed in order to achieve high fidelity reproduction. Things are spreading rapidly.

That is, this CD system has a diameter of 12 cm and a thickness of 1.2 m.
A transparent resin disk of m is coated with a metal thin film that forms pits corresponding to digital (PCM) data (concave and convex portions where different light reflectance can be obtained by "1" and "0"). Approximately 500-200r.pm of disk by CLT (constant linear velocity) method
Is rotated at a variable rotation speed, and is reproduced linearly from the inner circumference side to the outer circumference side by an optical pickup incorporating a semiconductor laser and a photoelectric conversion element.

In this case, a CD has a huge amount of information recorded on one side that enables stereo reproduction for about one hour, and has a higher recording density than the conventional analog type disc. From the point of view, it has been established in principle that it can be remarkably excellent.

By the way, it has been considered to use, for example, a commercial multi-disc automatic performance device as a method of utilizing the excellent features of such a CD.

That is, this is equivalent to a so-called jukebox or karaoke device that has been put to practical use even in the case of an analog disc, and can be realized by a disc autochanger device.

However, this type of disc autochanger device known in the related art has a problem in terms of operability because it has a complicated structure and a large size because it is intended for an analog type disc. It was
In addition, there is a problem that the number of disks to be stored cannot be increased so much and the disk replacement speed cannot be increased so much due to the demand for reliable operation.

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

The same applies to the case of a laser video disk, and the same applies to an optical disk file system which has recently been put into practical use as a part of so-called electronic file conversion.

[Object of the Invention]

Therefore, the present invention has been made in view of the above points, and is a very good disk in which a part of the disk accommodated in the entire tray can be simply and surely replaced with another disk by using the auxiliary tray. It is intended to provide an autochanger device.

[Outline of Invention]

That is, the disc autochanger device according to the present invention is a disc autochanger device capable of automatically searching a predetermined disc stored in a tray and exchanging and supplying the disc to a disc playing portion. A main tray mechanism and an auxiliary tray mechanism for separately storing a disc and a small number of discs are arranged side by side in the main body, and the main tray mechanism among these is fixed to the main body and the auxiliary tray mechanism can be inserted into and removed from the main body. In addition, a disc stop member facing or not facing the disc loading / unloading side of the auxiliary tray mechanism is provided in association with the loading / unloading of the auxiliary tray mechanism with respect to the main body.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will now be described in detail as an embodiment of the present invention when applied to a multi-disc automatic playing device for CDs with reference to the drawings.

The main part of the present invention is described with reference to FIGS. 13 to 16, but in order to deepen the understanding of the invention, the entire structure and operation of the disc autochanger device will be described step by step. Let's go.

FIG. 1 is a front external view of a cabinet 100 that accommodates a disc autochanger mechanism, which will be described later. 101 is a main tray accommodating unit that can accommodate a large number of discs (60 in this case), and 102 is a small number. (1 in this case
It is an auxiliary tray storage part that becomes a plus one tray if it is possible to freely take in and out disks.

Further, 103 is a performance state designating operation unit such as start, pause, cancellation of play, and redo, 104 is a key operation unit and a display unit thereof for allowing reservation of up to 5 songs, and 105 is a pitch (tempo) of the song. ) Control and key control display section, 106 is a signal level display section, 107 is a ten-key operation section, 108 is a display section of the currently playing song, and 109 is a display section of the next playing song.

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

2 and 3 are a perspective view and a plan view of the disc autochanger mechanism taken out from the cabinet 100 of FIG. 1, showing a relationship between the main chassis 121 and the left and right side chassis 122, 123 as described later. It has a main tray mechanism section 200 , an auxiliary tray mechanism section 300, and a disk search performance mechanism section 400 mounted in the above.

The operation of the automatic changer mechanism will be described briefly. A main tray mechanism unit 20 in which a predetermined number of discs 201 are stored in a disc storage groove 203 of a tray body 202, which will be described later, vertically arranged side by side at a predetermined pitch.
With respect to 0 (or the auxiliary tray mechanism unit 300 ), first, the disc search performance mechanism unit 400 moves in the directions of the arrows (A) and (B) in the figure based on the disc access information to search for the target disc 201. With that disc 2
01 is taken out and it becomes a performance state, then the relevant disc 201
Is returned to the original position on the main tray mechanism section 200 or the auxiliary tray mechanism section 300 after the performance, and then the same operation as described above is repeated based on the next disc access information.

In this case, the main tray mechanism section 200 has its synthetic resin tray body 202 removably supported on the left and right tray support bases 253 and 254 that are erected on the main chassis 121.

In addition, the auxiliary tray mechanism unit 300 has an auxiliary tray drive mechanism 350, which will be described later, for the auxiliary tray 301 so that an arrow (C),
It is supported so that it can move in and out in the (D) direction.

Further, the disc search performance mechanism unit 400 is configured by integrally integrating a disc search unit 500 , a disc transfer mechanism unit 600 and a disc performance mechanism unit 700, which will be described later, and is supported by the main chassis 121. Using the rail 401 and the guide shaft 402 thus formed as guides, a driving force of a search wire 403, which will be described later, causes an arrow (A) in the drawing,
It will be moved in the (B) direction.

Reference numeral 404 in FIG. 3 denotes an address plate made of synthetic resin supported on the main chassis 121, which is the main tray mechanism section.
Formed on 200 tray bodies 202. In this case, a pattern by a binary method capable of optically detecting an absolute address corresponding to one to one is formed in the 60 disk storage grooves 203. However, the support structure of the address plate 404 for the main chassis 121 will be described later.

Next, details of each of the above units will be described in order.

FIG. 4 (a) shows the main tray mechanism section 200 taken out above, and shows a tray main body 202 having 60 disk storage grooves 203 each having a substantially 1/4 semicircular shape, and the tray main body 20.
2, a U-shaped disc hold lever 205 that is rotatably supported via both sides of a spring 204, an attachment / detachment guide portion 206 that is also formed on both sides, and each inlet / outlet portion of the disc storage groove 203. Corresponding to the above, 60 slits 207 for positioning are formed as shown in FIG.

5 (a), (b), and (c) are a cross-sectional side view, a side view, and a front view showing the details of the tray main body 202, respectively, showing the radius of curvature R ₁ suitable for the disc 201 to be housed. 60 disc storage grooves 203 each having a trough and a predetermined shape as will be described later, that is, a partition wall 208 having a predetermined height and having a substantially 1/4 semicircular shape, have a predetermined pitch in the longitudinal direction (shown in the drawing). If 1.2
(4 mm for CD with mm thickness, however, the valley width at the entrance is 1.4 mm and the valley width at the back is 2.8 mm, which is flared.)
And each of the disc storage grooves are formed continuously.
A notch portion 209 and a locking portion 210 are formed in each bottom portion of 203, and the above-mentioned slit 207 is formed in each entrance / exit portion.

Here, the partition wall 208 of the disc storage groove 203 is the disc 201.
The height of each part in the storage direction of the disc 201 is set so as to prevent the tip of the disc 201 from hitting the top of the partition wall 208 and preventing the disc from being stored when the disc is stored.

That is, the disc 201 is stored while slidingly contacting the groove bottom portion in the direction of the arrow (E) in the drawing, but if no consideration is given to the height of the partition wall 208, the disc 201 is stored in the disc storage groove 203. When 201 is tilted in the direction orthogonal 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, if it is said that the top of each part of the partition wall 208 is located on a line that is inclined outward from the tangent line (Q) of the disk outer circumference circle (P) at each position in the storage direction of the disk 201. If the radius of curvature is set to be larger than that of the disc 201, the disc 201 can be smoothly stored without causing the above-mentioned problems.

In FIG. 4, 209 is a notch for pushing up the disc, which is formed continuously with the bottom of each of the disc accommodating grooves 203, and 210 is for locking the tray body formed on one side of the notch 209. The step-like locking portion has a detailed configuration, which will be described later.

Further, reference numeral 270 is a drawer unit described later.

FIG. 6 is an exploded perspective view for explaining the attaching / detaching procedure of the main tray mechanism unit 200 as described above, and the guide boss 255 provided on the pair of left and right tray support bases 253, 254 at the time of mounting.
The attachment / detachment guide portions 206 formed on both sides of the tray body 202 may be inserted into the rails 256 in the direction of the arrow (F) in the drawing.

However, in this case, before the insertion, the disc hold lever 205 is in the position shown by the solid line in the figure, which is rotated in the direction of the arrow (G) in the figure by the biasing force of the spring 204 in advance, and any disc 201 from the tray body 202 is careless It is possible to commonly prevent falling off.

Then, in the insertion process in the direction of the arrow (F), the disc holding lever 205 has its both end engaging portions 257 at the tray support base.
The lock pins 258 and 259 provided on the reference numerals 253 and 254 are engaged to rotate in the direction of the arrow (H) in the drawing so as to reach the position indicated by the chain line in the drawing, and are locked at the final position in the insertion direction.

FIG. 7 is a progress view for explaining such an inserted (locked) state, in which (a) shows that the locking portion 257 of the disc hold lever 205 becomes the lock pins 258, 259 during the insertion process in the direction of the arrow (F). It is in a contact state. Further, (b) shows a state in which the locking portion 257 passes through between the lock pins 258 and 259 by the further insertion, and the disc hold lever 205 is rotated in the arrow (H) direction in the figure. (C) shows a state in which the locking portion 257 of the disc hold lever 205 is engaged with the lock pin 258 and locked by the biasing force of the spring 204 by being further inserted.

Then, when the mounting of the main tray mechanism unit 200 is completed,
As shown in FIG. 2, since the disc hold lever 205 is rotated to the position corresponding to the position of the chain line in FIG. 6, the disc 201 accommodated in the main tray mechanism section 200 is rotated.
It is commonly possible to selectively take in and out.

When the mounting is completed, as shown in FIGS. 6 and 8, the roller 261 supported at the tip of the tray pressing lever 260 provided on the back side of the tray support 253 has the window portion 25.
3A, the tip of the attachment / detachment guide portion 206 of the tray body 202 is pressed in the direction of the arrow (I) in the figure by the biasing force of the spring 262, and also in the X shape through the spring 267. Rollers 265, 266 supported at the respective tips of the pair of tray lateral pressing levers 263, 264 engaged with each other.
The tray main body 2 because it has entered through the windows 253b and 253c.
The corresponding side end of 02 is pressed in the arrow (J) direction.

As a result, the mounting of the main tray mechanism unit 200 is completed as shown in FIGS. 2 and 3, and in the mounting completed state, the main tray mechanism unit 200 is fixed without rattling due to the locking action and the pressing action as described above. It will be.

By fixing the main tray mechanism section 200 , the tray main body 202 can be thermally expanded and contracted on the left end side with respect to the right end side in FIGS. 2 and 3.

Further, since the address plate 404 needs to be supported in a one-to-one correspondence with the disk storage grooves 203 and the slits 207 of the tray main body 202, the address plate 404 is attached to the main chassis 121 as shown in FIGS. 2 and 8. On the other hand, it is also supported thermally via the leaf spring 268 and a cushioning member 269 such as rubber so that the right end side can expand and contract with respect to the left end side.

With this, even if the ambient temperature changes,
If the tray main body 202 and the address plate 404 are made of the same kind of synthetic resin and are made of materials having the same thermal properties, the disc housing grooves 203 and slits 207 of the tray main body 202 and the address plate 404 are formed. Since the amount of thermal expansion and contraction is the same as that of the absolute address detection pattern, and a one-to-one relationship is maintained, it is possible to always perform accurate address detection (access) and positioning described later. There is something.

When the main tray mechanism unit 200 is taken out from the main body, first, in order to release the locked state, the disc hold lever at the solid line position shown in FIGS.
Draw a hand 2 on the lower part of the tray body 202 after holding the hand 205 and pressing the lever 205 slightly downward.
It suffices to hold 70 and pull it out in the arrow (M) direction opposite to the above insertion direction.

FIG. 9 is a progress view for explaining such a pulled-out (unlocked) state. FIG. 9A shows the lever 205 immediately after the disc lever 205 is pushed down in the arrow (K) direction.
The engagement between the locking portion 257 and the lock pin 258 is released. (B) is a state in which when the tray main body 202 is pulled out in the direction of the arrow (L), the locking portion 257 of the lever 205 passes through between the lock pins 258 and 259 and can be pulled out in the same direction.

When the main tray mechanism unit 200 is completely pulled out, the disc hold lever 205 is returned to the position indicated by the chain line in FIG. 10, that is, the position indicated by the solid line in FIG. 6 by the biasing force of the spring 204. It is possible to prevent the disc 201 from being accidentally dropped from the tray main body 202 at the time and after pulling out.

In the process of pulling out, the main tray mechanism unit 200 can be pulled out with the disc hold lever 205 held down in the direction of the arrow (K) in the figure. However, the locking portion 257 of the lever 205 is actually engaged with the lock pin 259 as shown in FIG. 7A during the pulling-out process as described above. As the lever 205 is forcibly released from the hand, the lever 205 is allowed to rotate in the direction of the arrow (G) shown in the figure, and returns to the solid line position before insertion as shown in FIG. Then, the effect of preventing the disc from coming off can be surely obtained.

As described above, the main tray mechanism unit 200 can be stably attached and detached.

By the way, if the main tray mechanism unit 200 is mounted in the main body, the disk 201 may be accidentally dropped from the tray main body 202 in the main body due to external vibration or the like given to the main body in this state.

For this reason, as shown in FIG. 11, a disc stop wire 406 whose both ends are locked to the front end of the disc search performance mechanism 400 via springs 405 is provided on the side chassis 12
The pulleys 407, 408 and 409, 410 supported by 2,123 are stretched in a loop so that the arrows (A),
Disc search performance mechanism 400 moved in the (B) direction
Since the disc stop wire 406 is interlocked with any position of the disc stop wire 406, the disc stop wire 406 is stored in the tray body 202 of the main tray mechanism unit 200 as shown in FIG. The disc 201 is also opposed to the disc 201 (see FIG. 3), so that it is possible to prevent the disc from accidentally falling off in the main body.

When any of the discs 201 stored in the main tray mechanism unit 200 is searched and played by the disc search performance mechanism unit 400, as will be described later, the main tray mechanism unit 200 cannot be taken in and out. ing.

FIG. 13 shows the above-mentioned auxiliary tray mechanism section 300 as an essential part of the present invention, and shows the auxiliary tray 301 in this case pulled out in the direction of the arrow (C).

That is, the auxiliary tray 301 in this case is a single disc 201.
1/4 semicircular disk storage groove 302 that can store
Having a front part and an auxiliary tray chassis 303 at the rear part and formed of a synthetic resin or the like, and the auxiliary tray chassis 303 part is divided into upper and lower parts near the right side chassis 123. The guide tray 304 and the lower rail 305 are slidably supported in the directions of arrows (C) and (D) in the drawing through sliding bearings 306 and 307 and rollers 308, respectively, and the auxiliary tray chassis 303 is also provided.
The rack 309 that is integrally formed on the back side of the tray is connected to the auxiliary tray drive mechanism 350, which will be described later, so that the first and second operations of the operation portion 112 for inserting and removing the auxiliary tray in FIG. 1 described above are performed. In response to the above, it can be freely withdrawn and withdrawn so that it is automatically withdrawn from the body and withdrawn.

When the auxiliary tray 301 is pulled out as shown in FIG. 13, the disc storage groove portion 30 will be described later.
By rotating the disc stop lever 310 so as to be located at the rear of 2, it is possible to prevent the disc 201 from falling off to the rear side.

In addition, in FIG. 13, the auxiliary tray 301 is connected to the bottom of the above-mentioned disc storage groove 302 and is provided with a notch 380 for pushing up the disc and a stepped locking for locking the auxiliary tray at one side of the notch 380. The portion 381 is formed, and details of these will be described later.

The disc storage groove 302 formed on the auxiliary tray 301
Regarding the height of each part of the partition wall 382, the same consideration as that of the partition wall 208 of the disk storage groove 203 formed in the tray main body 202 of the main tray mechanism part 200 is taken into consideration.

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

FIG. 14 is a detailed view of the above-mentioned auxiliary tray drive mechanism 350. The drive force from the motor 351 is worm gear 352 → worm wheel gear 353 → clutch gear 354 → first gear.
355 → second gear 356 → third gear 357 → fourth gear 358 through the series of power transmission paths, the above auxiliary tray chassis
It is designed so that it can be transmitted to a rack 309 integrated with 303.

Here, the clutch gear 35 inserted in the power transmission path
4 is for limiting the maximum torque finally transmitted to the rack 309 to prevent undesired biting between the worm gear 352 and the worm wheel gear 353.

FIGS. 15 (a) and 15 (b) show the disc stop lever 31.
It is assumed that the auxiliary tray 301 is pulled in the direction of the arrow (D) in the figure by rotating the motor 351 of the auxiliary tray drive mechanism 350.

That is, in this case, before the start of the pulling-in operation, as described above, the disk stop lever 310 rotatably supported on the rear side portion of the auxiliary tray 301 has one end stoppered by the biasing force of the spring 311. The other end of the disc storage groove 30
It is located at the rear of 2, that is, the position facing the disc entrance / exit.

When the pulling-in operation is performed, the roller 313 supported at one end of the disc stop lever 310 is in the process.
Swash plate cam 314 provided on the main chassis 121
The disk stop lever 310 is rotated in the direction of the arrow (N) in the counterclockwise direction in the drawing against the biasing force of the spring 311 because the disk stop lever 310 comes into sliding contact with the inclined portion.

As a result, the disc stop lever 310 serves as a disc entrance / exit portion such that the other end thereof is separated from the rear of the disc accommodating groove portion 302 of the auxiliary tray 301 as shown in FIGS. 16 (a) and 16 (b) when the pulling operation is completed. The disc search performance mechanism section, which will be described later, is set at non-opposing positions.
The disc 201 can be taken in and out by 400 .

In the above, the disc stop lever 310, the spring 311, and the stopper 312 constitute the disc stop member in the present invention.

Even when the auxiliary tray 301 is thus pulled in, the disc stop wire 406 prevents the disc 201 accommodated in the disc accommodating groove 302 from being accidentally dropped in the main body. .

Needless to say, when the auxiliary tray 301 is pulled out, the route opposite to that described above is followed and finally the state shown in FIG. 13 is reached.

It should be noted that the disc 201 stored in the auxiliary tray mechanism unit 300 has a disc search performance mechanism unit 4 as described later.
While being searched and played by 00 , the auxiliary tray 301 cannot be taken in and out, as in the case of the main tray mechanism section 200 described above.

Further, in this case, the disc 201 housed in the auxiliary tray mechanism unit 300 is searched and put into the playing state only after the disc search playing mechanism 400 is brought into the driving state as described later. If the auxiliary tray 301 is retracted before or during the retracting operation, the auxiliary tray 301
The disc 201 stored in the 301 is liable to malfunction because the player cannot search the disc 201 and put it in the playing state.

Therefore, as shown in FIG. 17, the auxiliary tray loading / unloading operation unit 112 (see FIG. 1) is different from the access start designating operation unit 103 (see FIG. 1) of the disc 201 stored in the auxiliary tray 301. The start signal is supplied to the drive control circuit 371 via the priority circuit 370 that gives priority to the operation by. Accordingly, when the first (drawing) operation of the auxiliary tray loading / unloading operation section 112 is performed, the access start designation operating section 103 is provided from the second (retracting) operation until the time required for pulling in. The start signal from the drive control circuit 371 is prevented from being supplied to the auxiliary tray loading / unloading operation unit 112.
Is prioritized over the operation of the access start designating operation unit 103, so that the search operation and the performance operation of the disc 201 accommodated in the auxiliary tray 301 can be ensured without causing the above-mentioned malfunction. It will be.

In other words, in this case, the disc search performance mechanism section 400 is set to the driven state only after the auxiliary tray 301 has been completely pulled into the predetermined position in the main body by the auxiliary tray drive mechanism 350. is there.

The auxiliary tray detection switch 372 shown in FIG.
3 is a micro switch provided in the rear part of the side chassis 123 in FIG. 3, which allows the reception of the start signal by the operation of the access start designating operation unit 103 after detecting the completion of the withdrawal of the auxiliary tray 301 by the auxiliary tray detection switch 372. Even if it is configured to do so, the above-mentioned malfunction can be prevented.

FIG. 18 is a conceptual diagram of the disc autochanger device as described above. Each operating portion 103, shown in FIG.
Based on various operation command signals from the operation unit 910 including 104, 105, 107 etc., the main tray mechanism unit 200 is driven by driving each of the above mechanism units 350, 400 to a predetermined state via a control circuit 920 such as a microcomputer. Alternatively , the desired disc 201 can be automatically replaced and played from the auxiliary tray mechanism section 300 .

The display unit 930 shown in FIG. 18 includes the display units 104, 105, 106, 108, 109 and the like as shown in FIG.

Here, the features of the essential parts of the present invention in the above-described disc autochanger device will be described.

That is, the feature of a principal part of the present invention, the auxiliary relates tray mechanism 200, facing or not facing the auxiliary tray mechanism 200 in conjunction with being and out relative to the body in the disk loading and unloading side of the auxiliary tray mechanism The point is that a disc stop member such as a disc stop lever 310 is provided.

In other words, this prevents the disc 201 from accidentally falling in the main body when the auxiliary tray mechanism 300 that can be automatically moved in and out separately from the main tray mechanism unit 200 described above is pulled out. This is because the disk 201 can be taken in and out when it is pulled in the main body. This allows the user to easily and surely replace a part of the disc stored in the entire tray with another disc by using the auxiliary tray mechanism 300 .

Next, as other features, items that characterize the main tray mechanism unit 200 and the auxiliary tray mechanism unit 300 as described above will be described.

First, as the first point, the tray body 202 or the auxiliary tray 3
Regarding the structure of 01, it has a disc storage groove 203 or a disc storage groove portion 302 that holds a substantially 1/4 semicircular portion of the disc 201, but the partition wall 208 or 382 has the top of each portion of the disc 201. The point is set so as to be located on a line inclined to the outside of the tangent line of the disk outer circumference circle at each position in the storage direction.

In other words, this allows the disc 2 to be stored when storing the disc 201.
This is because it is possible to prevent the tip portion of 01 from hitting the top of the partition wall 208 or 382 and being unable to be stored, which can contribute to smooth storage of the disc 201.

Secondly, regarding the main tray mechanism unit 200 that is detachable from the main body, the main position is set so as to commonly prevent the disc 201 from falling from the tray main body 202 when the main tray mechanism unit 200 is detached from the main body. One of the points is that a disc holding member such as a disc holding lever 205 which is in the second position and which allows the disc 201 to be selectively taken in and out from the tray main body 202 in common when mounted inside is provided.

In other words, this allows the main tray mechanism section 20
This is because it is possible to prevent the disc 201 from inadvertently dropping in the state where 0 is removed, and it is possible in common to selectively take in and out the disc 201 when mounted in the main body.

A third point is that the main tray mechanism section 200 is the same as the main tray mechanism section 200 , but is locked by being locked in the main body with a lock member such as the disc hold lever 205, so that the lock state is removed unless it is forcibly released. It is possible to prevent the accidental disengagement of the disk 201 and to contribute to the prevention of the drop of the disk 201.

As a fourth point, similarly, regarding the support structure of the main tray mechanism unit 200 , the support structure of the address detection member such as the address plate 404 for address detection is thermally set to the same condition, and one side is used as a reference. By making the other side thermally expandable, it is possible to always perform accurate address detection (access) and positioning.

Fifthly, regarding the main tray mechanism section 200 and the auxiliary tray mechanism section 300 , both discs 201 housed in these are stored in predetermined positions in the main body.
One of the points is that the disk stop wire 406 is stretched in a loop shape so as to be free to run in a state of opposing both ends of the disk stop wire 406 with both ends thereof being locked to the disk search performance mechanism 400 .

That is, this can prevent the disc 201 from being accidentally dropped from the tray body 202 or the auxiliary tray 301 in the body.

The sixth point is that the auxiliary tray mechanism section 300 is the same as the auxiliary tray drive section 350 so that the disk search performance mechanism section 400 is not driven until the auxiliary tray drive mechanism 350 has completely retracted the auxiliary tray 301 to a predetermined position in the main body. The points that have been done are listed.

That is, as a result, if the auxiliary tray 301 is not in the predetermined position in the main body as before or during the retracting operation of the auxiliary tray 301, the disc search performance mechanism 400
This is because it is possible to prevent in advance the malfunction that occurs when the disc is driven, that is, the search and the performance of the disc 201 stored in the auxiliary tray 301 cannot be performed.
