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, DAD (Digital Audio Disk) playback devices using PCM (Pulse Code Modulation) technology have been developed to achieve as high fidelity playback as possible. The CD method is rapidly spreading.

That is, this CD system has a diameter of 12 cm and a thickness of 1.
A 2 mm transparent resin disk coated with a metal thin film that forms pits (concave and convex portions where different light reflectance can be obtained by "1" and "0") corresponding to digital (PCM) data. Approximately 500-200r. Of disk by CLT (constant linear velocity) method.
It is rotated at a variable rotation speed of pm, and is reproduced linearly from the inner circumference side to the outer circumference side by an optical pickup that incorporates a semiconductor laser and a photoelectric conversion element.

In this case, the CD has a huge amount of information recorded on one side that enables stereo reproduction for about 1 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, as a method of utilizing the excellent characteristics of such a CD, for example, it is considered to be a commercial multi-disc automatic performance device.

That is, this is equivalent to what is called a juke box or a karaoke device, which has been put to practical use in the case of an analog disc, and can be realized by a disc auto-changing device.

However, since this type of disc auto-changing device which has been conventionally known is intended for an analog type disc, it has a complicated structure and a large shape, which causes a problem in operability. I got it. 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 auto-changer device for CD as described above as it is, and it is urgent to develop a disc auto-changer device suitable for CD. It was said to be an issue.

In addition, even in the case of a laser video disk, such a situation is
The same applies to the case where the present invention is applied 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 it is possible to increase the number of disks that can be stored in a volume that is as small as possible and to contribute to the improvement of the disk replacement speed. Moreover, it is an object of the present invention to provide an extremely good disc auto-engineer device which can satisfy the demand for reliable operation with a simple structure.

[Outline of Invention]

That is, the disc autochanger device according to the present invention is a disc autochanger device capable of automatically searching for a predetermined disc stored in the tray body and exchangeably supplying it to the disc playing portion. It has a large number of disc storage portions that are freely formed and have a predetermined pitch and that store a large number of discs to be exchanged and supplied, and the disc storage portion is stored in the disc storage portion on the back side thereof. In addition to having a disc receiving portion that abuts on a part of the outer periphery of the plurality of discs and regulates the position of the discs, the front surface side of the discs allows the plurality of discs stored in the disc storage portion to be taken out. It has an opening that exposes a part of the outer circumference, It is rotatable along the outer peripheral direction of the disc, and when the tray main body is not attached to the main body of the disc autochanger device, it rotates on the outer peripheral side of the disc toward the opening side of the disc storage portion. To prevent the disc stored in the disc storage unit from falling off, and when the tray body is attached to the disc autochanger device body, the disc is attached to the disc receiving portion side of the disc storage portion. It is characterized by comprising a tray main body provided with a disc holding member for rotating the outer periphery of the disc and taking out the disc from the disc storage portion.

Hereinafter, a case where the present invention is applied to a multi-disc automatic playing device for a CD will be described in detail with reference to the drawings.

FIG. 1 shows a front external view of a cabinet 100 that accommodates a disk autochanger mechanism, which will be described later. 101 is a main tray storage unit capable of storing a large number (60 in this case) of disks, 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, release of performance, 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. ) A 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.

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

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

The operation of the automatic chain mechanism will be described briefly. A main tray mechanism unit in which a predetermined number of disks 201 are stored in a disk storage groove 203 of a tray body 202, which will be described later, vertically arranged side by side with predetermined pitches.
For 200 (or the auxiliary tray mechanism section 300 ), first, the disk search performance mechanism section 400 moves in the directions of arrows A and B in the figure based on the disk access information to search for the target disk 201 and at the same time. To bring it into a playing state, and after returning the disk 201 to the original position on the main tray mechanism section 200 or the auxiliary tray mechanism section 300 after the performance is finished, based on the next disk access information, the same as above. It is designed to repeat the operation.

In this case, the main tray mechanism unit 200 has its synthetic resin tray body 202 removably supported on the left and right tray support bases 253 and 254 erected on the main chassis 121, as will be described later.

Further, the auxiliary tray mechanism section 300 has an auxiliary tray 301 supported by an auxiliary tray drive mechanism 350, which will be described later, so as to be able to move in and out in the directions of arrows C and D in the drawing.

Further, the disk search performance mechanism unit 400 is configured by integrally integrating a disk search unit 500 , a disk transfer mechanism unit 600, and a disk performance mechanism unit 700, which will be described later, into a unit and is supported by the main chassis 121. The rail 401 and the guide shaft 402 are used as guides to be moved in the directions of arrows A and B in the figure by the driving force of the search wire 403 described later.

Incidentally, reference numeral 404 in FIG. 3 denotes a synthetic resin address plate supported on the main chassis 121, which is formed in the tray main body 202 of the main tray mechanism section 200 in this case, and is paired with 60 disk storage grooves 203. A pattern by a binary method capable of optically detecting an absolute address corresponding to 1 is formed. However, the support structure of the address board 404 for the main chassis 121 will be described later.

 Next, details of each of the above-mentioned units will be described step by step.

FIG. 4 (a) shows the main tray mechanism section 200 extracted from the 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.
A U-shaped disc hold lever 205 rotatably supported between both side portions of the 202 via a spring 204, an attachment / detachment guide portion 206 also formed on both side portions, and an entrance / exit portion of the disc storage groove 203. Correspondingly, it has 60 slits 207 for positioning, which are formed as shown in FIG.

5 (a), (b) and (c) show the tray body 202.
The sectional side view, the side view, and the front view showing the details of the above, in which the radius of curvature R ₁ adapted to the disc 201 to be housed is a valley and the peak portion of a predetermined shape as will be described later, that is, a partition wall of a predetermined height 60 disk storage grooves 203 having 208 and having a substantially 1/4 semicircumferential shape have predetermined pitches in the longitudinal direction (in the case shown,
4mm for a 1.2mm thick CD, but with a trough width of 1.4m at the entrance
m and the valley width at the back is 2.8 mm, which is a divergent shape at the end), and a notch 209 and a lock 210 are formed at the bottom of each disk storage groove 203. The above-mentioned slit 207 is formed at each entrance / exit.

Here, the partition wall 208 of the disk storage groove 203 is the disk 20.
When storing 1, the tip of the disk 201 is separated by the partition wall 208.
To prevent it from hitting the top of the and becoming impossible to store,
The height of each part in the storage direction of the disk 201 is set.

That is, the disk 201 is stored while slidingly contacting the groove bottom 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 201 is stored in the disk storage groove 203. When 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.

For this reason, the top of each part of the partition wall 208 is the disk 201.
If the disk 201 is set so as to be located outside the tangent line Q of the disk outer circumference circle P at each position in the storage direction, the disk 201 can be stored smoothly without causing the above-mentioned problems.

Numeral 209 in FIG. 4 is a notch for pushing up the disk, which is formed by being connected to the bottom of each of the disk housing grooves 203, and 210 is for a tray main body lock 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 attachment / detachment procedure of the main tray mechanism unit 200 as described above. The guide boss 2 provided on the pair of left and right tray support bases 253, 254 at the time of attachment is shown.
The attachment / detachment guide portions 206 formed on both sides of the tray main body 202 may be inserted into the 55 and the rail 256 in the direction of arrow F in the drawing.

However, in this case, before the insertion, the disc hold lever 205 is preliminarily rotated in the direction of the arrow G in the figure by the biasing force of the spring 204, and any disc 201 from the tray body 202 is carelessly moved. It is possible to commonly prevent falling off.

Then, in the insertion process in the direction of the arrow F, the disk hold lever 205 has its both end locking portions 257 at the tray support base 25.
The lock pins 258, 259 provided on 3, 254 are engaged to rotate in the direction of the arrow H in the drawing so as to reach the position shown by the chain line in the drawing, and are locked to the final position in the insertion direction.

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

When the mounting of the main tray mechanism section 200 is completed, as shown in FIG.
6 is rotated to a position corresponding to the position of the chain line in FIG. 6, the disk 2 stored in the main tray mechanism unit 200
01's selective withdrawal is commonly possible.

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.
Since it has entered from 253a, the tip of the attachment / detachment guide portion 206 of the tray main body 202 is pressed in the direction of the arrow I in the figure by the biasing force of the spring 262, and the spring
Since the rollers 265, 266 supported at the respective ends of the pair of tray lateral pressing levers 263, 264 engaged in the X-shape via 267 enter through the window portions 253b, 253c, the tray main body 202
The corresponding side end of each is pressed in the direction of arrow J in the drawing.

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, rattling or the like occurs due to the locking action and the pressing action as described above. It will be fixed without.

By fixing the main tray mechanism unit 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 relationship with the disk storage grooves 203 and the slits 207 of the tray body 202, as shown in FIGS. Also, it is supported by a leaf spring 268 and a cushioning member 269 such as rubber so that the right end side can be expanded and contracted thermally with respect to the left end side as a reference.

As a result, even if the ambient temperature changes, if the tray body 202 and the address plate 404 are made of materials having the same thermal characteristics so that they are made of the same kind of synthetic resin, the tray body Each disk storage groove 203 and slit 207 of 202 and the pattern for absolute address detection of the address plate 404 have the same amount of thermal expansion and contraction, and a one-to-one relationship is maintained, so that accurate address detection (access )
Also, the positioning described later can be performed.

When the main tray mechanism unit 200 is taken out from the main body, first, in order to release the locked state, the user holds the disc hold lever 205 at the solid line position shown in FIGS. A little downward, and then pull out the drawer part 2 formed at the bottom of the tray body 202.
It suffices to hold 70 and pull it out in the direction of arrow M, which is opposite to the above insertion direction.

FIG. 9 is a progress diagram for explaining such a pulled out (unlocked) state. FIG. 9 (a) is a disk lever 205.
Immediately after pushing down in the direction of arrow K in the drawing, the engagement between the locking portion 257 of the lever 205 and the lock pin 258 is released. In (b), the tray main body 202 is pulled out in the direction of the arrow L, so that the locking portion 257 of the lever 205 is locked.
It is a state in which it can be pulled out in the same direction by passing through between 258 and 259.

When the main tray mechanism unit 200 is completely pulled out, the disc hold lever 205 is returned to the position shown by the chain line in FIG. 10, that is, the position shown by the solid line in FIG. 6 due to 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 during and after pulling out.

In the process of pulling out, it is possible to pull out the main tray mechanism unit 200 while holding the disc hold lever 205 and pushing it down in the direction of arrow K in the figure. Although the fall-out preventing effect cannot be achieved, in reality, as described above, the locking portion 257 of the lever 205 is not moved to the seventh position in the process of pulling out.
When the lever 205 is forcibly released from the hand in the state of being engaged with the lock pin 259 as shown in FIG. 7A, the lever 205 is allowed to rotate in the direction of arrow G in the drawing. As shown in FIG. 10, the disk returns to the solid line position before insertion, and the disk dropout prevention effect can be reliably achieved.

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

By the way, in this state, the disk 201 is carelessly set in the main body by the external vibration applied to the main body while the main tray mechanism section 200 is mounted in the main body.
There is a risk of being dropped from.

For this reason, as shown in FIG. 11, a disk stop wire 406 having its both ends locked to the front end of the disk search playing mechanism section 400 via springs 405 is attached to the side chassis 1.
The pulleys 407, 408 and 409, 410 supported by 22,123 are stretched in a loop so that the disk search performance mechanism section 400 moved in the directions of arrows A and B in the figure can be located at any position. , The disk stop wire 406 faces any disk 201 housed in the tray body 202 of the main tray mechanism section 200 as shown in FIG. 12 (FIG. 3). As a result, it is possible to prevent accidental disc drop in the main body.

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

FIG. 13 shows the above-mentioned auxiliary tray mechanism portion 300 taken out, and in this case, the auxiliary tray 301 is pulled out in the direction of arrow C in the drawing.

That is, in this case, the auxiliary tray 301 has one disk 2
1/4 semicircular disk storage groove 3 that can store 01
02 has a front part and an auxiliary tray chassis 303 at the rear part, and is made of a synthetic resin or the like. The auxiliary tray chassis 303 is the right side chassis 123.
With respect to the guide shaft 304 and the lower rail 305, which are separately arranged in the upper and lower sides, the slide shafts 306 and 307 and the roller 308 are slidably supported in the directions indicated by arrows C and D, respectively. The rack 309 portion integrally formed on the back side of the auxiliary tray chassis 303 is connected to the auxiliary tray drive mechanism 350 described later, so that the first tray
The auxiliary tray can be freely withdrawn and withdrawn so as to be automatically withdrawn and withdrawn from the main body in response to the first (drawing) and the second (withdrawing) operations of the operation portion 112 for taking in and out the auxiliary tray.

In the state where the auxiliary tray 301 is pulled out as shown in FIG. 13, the disk storage groove portion will be described later.
By rotating the disk stopper 310 so as to be located behind the disk 302, it is possible to prevent the disk 201 from falling rearward.

Further, in FIG. 13, the auxiliary tray 301 has a notch 380 for pushing up the disk connected to the bottom of the above-mentioned disk storage groove 302, and a stepped locking portion for one side of the notch 380 for the auxiliary tray lock. Although 381 is formed, the details of these will be described later.

The disk storage groove portion 3 formed on the auxiliary tray 301
Regarding the partition wall 382 of 02, the same consideration as the partition wall 208 of the disk storage groove 203 formed in the tray main body 202 of the main tray mechanism unit 200 is taken into consideration regarding the height of each part.

In addition, the disk storage groove portion 3 formed on the auxiliary tray 301
A slot 207 for positioning which is formed at the entrance / exit of the disk storage groove 203 formed in the tray main body 202 of the main tray mechanism unit 200 described above is provided at the entrance / exit of the 02 (rear in FIG. 13).
It is assumed that the same slit (not shown) is formed.

FIG. 14 is a detailed view of the above-mentioned auxiliary tray drive mechanism 350, in which the driving force from the motor 351 is transferred to the worm gear 352 →
Worm wheel gear 353 → clutch gear 354 → first gear 365 → second gear 356 → third gear 357 → fourth gear 358
The auxiliary tray chassis 303 is integrated with the rack 309 through a series of power transmission paths.

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

FIGS. 15 (a) and 15 (b) are the above-mentioned disposable levers.
310 is taken out and shown, and it is assumed that the auxiliary tray 301 is pulled in the direction of arrow D in the figure by rotating the motor 351 of the auxiliary tray drive mechanism 350.

That is, in this case, as described above, before the start of the pulling-in operation, the one end of the disk suspension lever 310 rotatably supported on the rear side portion of the auxiliary tray 301 has a biasing force by the spring 311. Since it is in contact with the stopper 312, the other end is in the disk storage groove.
It is located at the rear of 302, that is, at a position facing the entrance / exit of the disk.

Then, when the retracting operation is performed, the roller 3 supported at one end of the disk thruster 310 is in the process.
13 is a swash plate cam 3 provided on the main chassis 121.
Since it comes into sliding contact with the inclined portion of 14, the disk thruster 310 is rotated in the direction of the arrow N in the counterclockwise direction in the figure against the biasing force of the spring 311.

As a result, when the drawing operation is completed, the disk stopper 310 is arranged so that the other end thereof is separated from the rear of the disk storage groove 302 of the auxiliary tray 301 as shown in FIGS. 16 (a) and 16 (b). Since the disc 201 is located at a position not facing the entrance / exit portion, the disc 201 can be taken in and out by the disc search performance mechanism 400 described later.

Even when the auxiliary tray 301 is pulled in in this way, the disk stop wire 409 prevents the disk 201 stored in the disk storage groove 302 from being accidentally dropped in the main body. are doing.

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

When the disk 201 accommodated in the auxiliary tray mechanism section 300 is searched and played by the disk search performance mechanism section 400 as described later, the auxiliary tray mechanism section 300 is operated in the same manner as the main tray mechanism section 200 described above. Tray 301
It has been made impossible to put in and take out.

Further, in this case, the disk 201 housed in the auxiliary tray mechanism section 300 is searched and brought into the playing state only after the disk search playing mechanism 400 is brought into the driving state as will be described later. If the auxiliary tray 301 is drawn in before or during the retracting operation, the disk 201 stored in the auxiliary tray 301 cannot be searched and put into a playing state, which tends to cause a malfunction. .

Therefore, as shown in FIG. 17, the auxiliary tray 301
Through the priority circuit 370 in which the operation by the auxiliary tray loading / unloading operation unit 112 (see FIG. 1) is prioritized with respect to the access start designation operation unit 103 (see FIG. 1) of the disk 201 stored in The drive control circuit 371 is configured to be supplied with a start signal. As a result, when the first (pull-out) operation of the auxiliary tray loading / unloading operation section 112 is performed, the access start designation operation section 103 is provided from the second (pull-in) operation until the time required for pull-in. The start signal is not supplied to the drive control circuit 371, and the auxiliary tray loading / unloading operation unit 11
The operation 2 is prioritized over the operation of the access start designating operation unit 103, so that the search operation and the performance operation of the disk 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 400 is set in the driven state only after the auxiliary tray 301 is completely retracted to the predetermined position in the main body by the auxiliary tray drive mechanism 350. It is a thing.

Note that the auxiliary tray detection switch 372 in FIG. 17 is, for example, a micro switch provided in the rear part of the side chassis 123 in FIG. 13, and after the completion of the withdrawal of the auxiliary tray 301 is detected by the auxiliary tray detection switch 372. Even when the access start designation operation unit 103 is configured to allow the start signal to be accepted, the above-described malfunction can be prevented.

FIG. 18 is a conceptual diagram of the above-mentioned disc auto-changing device, in which each operating portion 10 as shown in FIG.
The main tray mechanism section 200 or the main tray mechanism section 200 is driven by driving each of the mechanisms 350 and 400 into a predetermined state through a control circuit 920 such as a microcomputer based on various operation command signals from an operation section 910 including 3,104,105,107 and the like. The auxiliary tray mechanism unit 300 automatically causes a desired disc 201 to be exchanged and played.

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

Next, the features of the main tray mechanism unit 200 and the auxiliary tray mechanism unit 300 as described above will be described.

First, regarding the structure of the tray main body 202 or the auxiliary tray 301, the first point is that it has the disk storage groove 203 or the disk storage groove portion 302 that holds the approximately 1/4 semicircular portion of the disk 201. The partition wall 208 or 382 is set so that the top of each part thereof is 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 of the disk 201.

In other words, this prevents the tip end of the disk 201 from hitting the top of the partition wall 208 or 382 when the disk 201 is stored and becoming unstorable, so that the disk 201 can be stored smoothly. This is because it can contribute to

The second point is that the main tray mechanism unit 200 that is detachable from the main body is commonly prevented from falling of the disk 201 from the tray main body 202 in a state of being removed from the main body.
The disk hold lever 205 is located at a second position that allows the disk 201 to be selectively placed in and taken out of the tray body 202 while being mounted in the body.
The point that a disc hold member such as the above is provided.

In other words, this allows the main tray mechanism section to be
This is because it is possible to prevent the disc 201 from inadvertently dropping in the state where the disc 200 is removed, and in the state where the disc 201 is mounted in the main body, it is possible to commonly selectively take in and out the disc 201.

The third point is that the main tray mechanism section 200 is the same as the main tray mechanism section 200 , but is locked by a lock member such as the above-mentioned disk hold lever 205 so that the main tray mechanism section 200 is in a locked state. It is possible to prevent the accidental disengagement of the disk 201 by making it impossible to prevent the disk 201 from falling, which in turn contributes to preventing the disk 201 from falling.

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 unit 200 and the auxiliary tray mechanism unit 300 , each of the disks 20 stored in the main tray mechanism unit 200 and the auxiliary tray mechanism unit 300 in a state where they are put in predetermined positions
One of the points is that the disk stop wire 409 is stretched in a loop shape so as to run freely with the both ends thereof being locked to the disk search performance mechanism section 400 so as to face the loading / unloading side of 1.

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

The Examples 6 points relates auxiliary tray mechanism 200, disk scan shoulder stop lever the auxiliary tray mechanism 200 is made with the opposite or non-opposite in conjunction with being and out relative to the body in a disk loading and unloading side of the auxiliary tray mechanism The point is that a disc stop member such as 310 is provided.

That is, as a result, the auxiliary tray mechanism 300 that can be automatically moved in and out separately from the main tray mechanism unit 200 described above.
This is because it is possible to prevent the disk 201 from accidentally falling in the main body when the disk is pulled out, and it is possible to take the disk 201 in and out when the disk 201 is drawn in the main body.

As the seventh point, regarding the auxiliary tray mechanism section 300 ,
One of the points is that the disk search performance mechanism section 400 is set in the driven state only after the auxiliary tray 301 has been completely pulled into a predetermined position in the main body by the auxiliary tray drive mechanism 350.

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

Next, before explaining the details of the disk search performance mechanism section 400 , first, the overall movement process of the disk 201 during loading and unloading will be schematically described.

This can contribute to effective promotion of

As a fifth point, with respect to the disk playing mechanism section 700 , a disk guide section 724 and a disk pocket section 729 for accommodating the disks 201 transferred by the disk transfer mechanism section 600 are provided so as to be able to move in and out of the turntable 721, respectively. One of the points is that the disk 201 is moved to the turntable 721 together with the disk guide portion 724 and the disk pocket portion 729 so that the disk 201 can be played.

That is, according to this, the disc 201 is housed in the disc guide portion 724 and the disc pocket portion 729 so as to be playably attached to the turntable 721, thereby effectively protecting the disc 201 and downsizing the device. This is because it can contribute to promotion.

As a sixth point, regarding the disk search performance mechanism section 400, passage of the disk 201 is detected by the first disk detector 652, and the disk pocket section 729 of the disk 201 is detected.
The second disk detector 734 detects the presence / absence of accommodation in the disk and controls each part to a predetermined state.

That is, according to this, the transfer path like the loading path 655 and the disk pocket portion 729 form a two-stage type disk drive 201.
In order to control each part in the state of detecting the
This is because it is possible to contribute to the improvement of safety in which a malfunction such as transferring 201 to the disc playing mechanism unit 700 is prevented.

Needless to say, the present invention is not limited to the above-described and illustrated embodiments, and various modifications and applications are possible without departing from the spirit of the present invention.

〔The invention's effect〕
