Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to an automatic recording disk selection and playback device that selects and plays one recording disk from a storage section that stores a large number of recording disks.

BACKGROUND ART One of this type of devices is a record disc automatic selection and playback device, a so-called joke box. In the conventional device, a large number of records are stored in a storage rack in a horizontal line facing each other, and the player body moves along the side of the rack to face a designated record. The arm member that holds the record rotates to take out the specified record, attach it to the player body, and play the record.
After the playback is finished, the arm member rotates in the opposite direction to remove the record from the player body and return it to its original position in the storage rack.

With this device, the records in the storage rack are lined up at relatively large pitch intervals, and played records can be reliably returned to the original storage section in the storage rack without any special mechanism. .

However, in an effort to downsize the device, the spacing between the records in the storage rack has become narrower, and when the played records are returned to the storage rack, they are not returned to their original storage section and are accidentally placed next to each other. There is a problem in that a malfunction may occur in which the product is returned to the storage section.

Means for Solving the Problems The object of the present invention is to provide a recording disc automatic selection and playback device that solves the above-mentioned problems, and includes a plurality of recording disc storage sections each accommodating a plurality of recording discs. a reproducing mechanism section that moves along the recording disk storage section, stops at a position facing the designated storage section, and is supplied with the recording disk in the storage section and plays it back; In an automatic recording disk selection and playback device comprising a recording disk return mechanism that detaches the recording disk from the playback mechanism and returns it to the original storage section, the position of a recording disk discharge port through which the recording disk returned to the original storage section passes. a protrusion mechanism that causes the alignment member to protrude from the reproduction mechanism section and is fitted into the original storage section, and a protrusion mechanism that allows the alignment member to be displaced in the direction in which the storage sections are lined up. A supporting mechanism is provided in the reproducing mechanism section.

Embodiment FIG. 1 shows a compact disc automatic selection and playback device 1 which is an embodiment of the recording disk automatic selection and playback device according to the present invention. Apparatus 1 is roughly frame 2
This is installed horizontally on the top of the disk, and multiple compact disks 3 (hereinafter referred to as disks)
The disc storage rack 4 is made up of a disc storage rack 4 for storing a disc storage rack 4, and a reproducing mechanism part 5 which has a built-in disc reproducing machine and is supported movably along the storage rack 4 at a position directly below the disc storage rack 4.

As shown in FIG. 2, the disk storage rack 4 has a generally rectangular frame shape, and both walls along the longitudinal direction are formed into a comb-teeth shape with a large number of partition wings 10 connected by side plates 11. Has a structure. A pair of adjacent partition wings 10 facing each other cooperate to form a flat disk storage section 12, and the storage rack 4
has a structure in which a large number, for example, 100 disk storage sections 12 are closely aligned in the longitudinal direction.
The 100 disk storage units 12 are sequentially numbered. Also, one slit 13 is formed corresponding to each disk storage section 12. Furthermore,
1 disk stopper for each disk storage section 12
4 is provided. The disk stopper 14 is connected to the shaft 15
It is supported by the partition blades 10 and arranged between adjacent partition wings 10, and is biased counterclockwise by a spring 16 and normally rotates in the same direction.
protrudes inward. Further, both the ceiling and the bottom of the storage rack 4 have openings 17 and 18.

The disk 3 is inserted into each storage section 12 through the upper opening 17 in a vertical state with the playback surface aligned in one direction. The inserted disk 3 has an outer peripheral edge 3a
The lateral parts A ₁ and A ₂ are locked by the side plates 11 to restrict rolling, and the lower part A ₃ is locked by the stopper 14 to restrict downward movement (fall). The discs are surely separated from the adjacent disks 3 on both sides by partition wings 10, and their inclinations are restricted so that they do not contact the adjacent disks on both sides, and are arranged in a vertical posture facing each other and stored in the storage rack 4. In other words, when each disk 3 is released from the stopper 14, it descends under its own weight, slips out of the storage section 12, passes through the bottom opening 18, and enters the storage rack 4 in a state where it can be removed from the storage rack 4. It is stored.

Here, since the arm 46, which will be described later, does not pass through the storage rack 4, it is not necessary to provide a gap large enough for the arm to pass between every other disk, and the disk 3 are arranged in small pitches. In this embodiment, the thickness of each partition blade 10 is about 1 mm, the pitch of the partition blades 10 is about 3 mm, and the disks 3 are tightly housed in a narrow pitch of about 3 mm. Therefore, even when storing as many as 100 disks 3, the length L of the storage rack 4 can be as short as about 30 cm, and the apparatus 1 is constructed in a small size.

The regeneration mechanism section 5 is supported by a pair of guide rods 20 and 21 which are horizontally suspended on the frame 2 on both sides, and when a pinion 23 rotated by a motor 22 rolls on a rack 24, the guide rods 20, 21 and moves in the directions of arrows X ₁ and X ₂ .

As shown in FIGS. 2 to 6, the playback mechanism section 5 includes a disk playback machine 25, a disk playback shift mechanism 26 that shifts the disk playback machine, and a rack 4 that simply supports the disc. A disk transport mechanism 27 that transports the disk to and from the playback mechanism section 5, a disk guide mechanism 28 that guides the disk discharged from the playback mechanism section, and an alignment mechanism that aligns the disk guide mechanism with a predetermined disk storage section 12 of the storage rack. 29, a disk clamping mechanism 30 that clamps the disk during playback, a disk separating mechanism 31 that separates the disks on both sides of the storage section to which the disk is returned when returning the disk to the storage rack, etc., each mechanism having a It is configured to operate in conjunction with the rotation of one cam gear 35 shown in FIGS. 7A to 7C. The cam gear 35 has a cam surface 35 shown in FIG.
It is supported by a shaft 37 at a substantially central position inside the outer panel 36 of the regeneration mechanism section 5, with A on the outside and the cam surface 35B shown in FIG.
It is rotated by a motor 38. FIG. 2 shows a mechanism operated by a cam on a cam surface 35A of the cam gear 35, and FIG. 3 shows a mechanism operated by a cam on a cam surface 35B as viewed from the direction of arrow C. 4 and 5 are views seen from the directions of arrows D and E, respectively. FIG. 6 is a diagram showing the configuration of the top side of the reproduction mechanism section.

In the playback mechanism section 5, a pair of guide panels 39 and 40 are arranged facing each other with a disk receiving/ejecting position P (shown at the bottom in FIGS. 4 and 5) in between. It enters the flat guide space 41 between the guide panels 39 and 40, where it rotates and is reproduced.

The disc playback device 25 has an arrow inside the playback mechanism section 5.
It is supported movably in the X ₁ and X ₂ directions, and in the initial state, as shown in Figures 4 and 5,
Moves in the X ₂ direction and is away from position P.

As shown in FIGS. 2 and 5, the disk player shift mechanism 26 has an upper portion pivotally supported by a part of the outer panel 36, and a lower end connected to a U-shaped support base 42 that supports the disk player 25. cam 35A- ₁ on the cam surface 35A side that acts on the shift arm 43 and the roller 44 in the middle of the shift arm 43.
Therefore, it operates after the disk 3 enters the playback mechanism section 5.

As shown in FIGS. 2 and 4, the disk transport mechanism 27 has a flat guide space 41 centered around a shaft 45.
a generally arc-shaped disk carrying arm 46 that rotates between the position shown by the solid line in FIG. 2 and the position shown by the two-dot chain line;
It has a rack 48 at one end that meshes with the pinion 47, and a boat-shaped cam follower 49 (Figs. 2 and 7C).
(shown in FIG. 1) and a lever 50 that moves in the directions of arrows _Y1 and _Y2 guided by a cam groove 35A- ₂ of a cam surface 35A. In the initial state, the lever 50 is moving in _{the two} directions of arrow Y, as shown in FIG.
Arm 46 is rotating counterclockwise. In addition,
A disk catcher 61 is attached to the tip of the arm 46 to support the outer peripheral edge 3a of the disk 3 while restricting free displacement of the disk 3 in the surface direction.

As shown in FIGS. 4 to 6, the disk guide mechanism 28 includes a pair of guide plates 51 and 52 arranged such that respective inclined guide portions 51a and 52a face each other.
It becomes more. The guide members 51 and 52 are urged toward each other by springs 53 and 54 on both sides, and the inclined guide portions 51a and 52a are butted against each other with alignment plates 55 and 56 sandwiched at both ends.
In this state, the inclined guide parts 51a and 52a have an inverted V-shape in side view and are in a state where they can guide the disk discharged from below to the upper side. An elongated opening 57 having a dimension slightly larger than the thickness is formed. The first guide plate 51 is guided by the cam groove 35B- ₁ of the cam surface 35B and rotated as shown in _FIG . It can be displaced to Information board 5
1 is displaced in this way, the levers 59 on both sides,
A further guide plate 52 is displaced via 60 in the direction of arrow _X2 . That is, both guide plates 51 and 52 are displaced in the direction away from each other, the opening width is increased, and the disc is in a state where it can easily enter into the playback mechanism section 5. Further, both guide plates 51 and 52 are attached so that they can be displaced somewhat in plane without changing the opening width, and are displaced according to the positions of alignment plates 55 and 56, as will be described later.

The alignment mechanism 29, which forms the main part of the present invention, includes alignment plates 55 and 56 that are disposed on both ends of the opening 57 so as to be displaceable in the directions of arrows _Z1 and _Z2 , and a cam surface 35.
Rotating arm 6 guided by cam groove 35A- ₃ of A
2, 63, and connecting arms 64, 65 that connect the rotating arms 62, 63 and the alignment plates 55, 56. In the initial state, the alignment plates 55 and 56 are displaced in the direction of arrow _Z2 and recessed into the reproduction mechanism section 5, and when the cam gear 35 rotates, the alignment plates 55 and 56 move the rotation arms 62 and 63 and the connecting arms 64 and 65. At the same time, they move in the direction of arrow _Z1 , project from the playback mechanism section 5, and enter the storage rack 4. Note that each alignment plate 55, 56 has a thickness slightly larger than the thickness of the disk 3, and this determines the width dimension of the opening 57 when guiding the disk.

The disk clamp mechanism 30 is shown in FIGS. 3 and 5.
As shown in the figure, a clamp arm 71 whose base side is supported by a shaft 70;
Disk clamper 7 on the tip side (shown in Figure 3)
2, and a cam groove 35B- ₂ of the cam surface 35B for rotating the clamp arm 71 and displacing the disk clamper 72 in the direction of arrow _X2 in FIG. 5 when the disk is clamped. In the initial state, the clamper 72 is located at a non-clamping position displaced in the direction of arrow _X1 .

As shown in FIGS. 3 and 6, the disk separating mechanism 31 includes a disk separator 73 on the guide plate 51 and a protrusion 35B on the cam surface 35B.
- a rotating arm assembly 74 which is rotated by being kicked by ₃ and displaces the disk separator 73 in the direction of arrow _Y1 . Disk separator 73
When moving in the direction of arrow _Y1 , the beak-shaped part 73
a enters the vicinity of the lower edge of the adjacent disks 3, forcibly separates the adjacent disks 3, and forms a path for the disks to be returned to the storage rack 4. Note that the disk separator 73 can be displaced by being guided by long holes 75a and 75b of the holding plate 75, and is normally moved in the direction of arrow _Y2 by a spring 76. Further, the rotating arm assembly 74 rotates when the cam gear 35 rotates in the arrow _B1 direction.
- When kicked by ₃ , the arm assembly itself bends and does not rotate, and when kicked by protrusion 35B- ₃ while the cam gear 35 is rotating in the arrow _B direction, it rotates counterclockwise. It is structured as follows.

Next, regarding the operation of the apparatus 1 having the above configuration, FIGS. 8A to F, FIGS. 9A to E, and FIG. 10A
This will be explained with reference to E.

8A shows the disk transport arm 46, B shows the positioning plates 55, 56, C shows the disk guide plates 51, 52, D shows the disk regenerator 25, E shows the disk clamper 72, FIG. F shows the operating state of the disk separator 73 according to the rotation angle of the cam gear 35. Figures 9A to E and Figure 10A
8 to E show changes in the operating state of the device 1 in correspondence with FIG.

In the initial state, the device 1 is shown in FIGS. 9A and 10A.
It is in the state shown below. That is, the disk 3 is locked to the disk stopper 14, the disk transport arm 46 is rotating counterclockwise, the positioning plates 55 and 56 are lowered, and the disk regenerator 25
Both the disk clamper 72 and the disk clamper 72 are separated from the position P, the disk guide plates 51 and 52 are separated from each other, and the opening 57 is in a half-open state.

The apparatus 1 starts operating by operating the operation panel to specify a disc to be played, and operates as described below.

When the operator specifies a predetermined address N, motor 2
2 starts and the pinion 23 rolls on the rack 24, so that the regeneration mechanism section 5
0, 21 and moves in the direction of arrow _X1 or _X2 , and the slit detector 80 detects the slit
3 is detected, that is, the disk receiving position P of the playback mechanism section 5 is stopped at a position directly below and facing the disk 3N in the disk storage section 12N at the designated address.

Next, the motor 38 is started and rotates forward, and the cam gear 35 is rotated approximately 280 degrees in the direction of arrow _B1 via the worm 81.
Rotate degrees. When the cam gear 35 rotates, the lever 50 moves in the direction of arrow _Y1 in FIG. 2, and the disk carrying arm 46 rotates clockwise to the position shown by the two-dot chain line in the same figure (see FIG. 8A). , the disk catcher 61 locks the lower end _A4 of the outer periphery 3a of the disk 3N in the storage section 12N of the rack ₄ , and moves the disk 3N as shown by the two-dot chain line (solid line in FIG. 9B). (as shown) lift it up a little so that it is above the disk stopper 14. Also, the rotating arm 62,
63 rotate counterclockwise and clockwise, respectively,
The alignment plates 55 and 56 both move in the direction of arrow _Z1 and rise (see FIG. 8B), and move into the storage section 12N in the storage rack 4, that is, between the adjacent partition wings 10 forming the storage section 12N. Enter into the gap. Furthermore, the expansion lever 58 operates as shown in FIG. 4, and the guide plates 51 and 52 move away from each other, so that the opening 57 is fully opened. . This brings the device 1 into the state shown in FIG. 9B.

When the cam gear 35 rotates further, the alignment plate 5
5 and 56 further enter into the storage section 12N, and the positioning plates 55 and 56 become in a state where they can be regarded as members protruding directly below both ends of the storage section 12N. Therefore, in this state, each alignment plate 55, 56 moves the guide plates 51, 52 to the storage section 12N when returning the disk, which will be described later.
It can play a role in regulating the position so that it matches the . Further, the alignment plate 56 on one side pushes up the disk stopper 14 and rotates it clockwise. Since the disc 3N is floating above the disc stopper 14, the weight of the disc 3N does not act as a load when the disc stopper 14 rotates in the direction of releasing the disc lock, and the disc stopper 14 releases the disc lock. The movements are light and smooth. As a result, the apparatus 1 enters the state shown in FIG. 9C, that is, the disk 3 is released from the disk stopper 14 and is instead supported by the disk transport arm 46 (disk catcher 61).

When the cam gear 35 further rotates, the lever 50 moves in the direction of the arrow _Y2 and moves the disk transport arm 46.
starts rotating counterclockwise. In response to the counterclockwise direction of the arm 46, the disk 3N descends under its own weight while being supported by the disk catcher 61, and reaches the ninth position.
As shown in FIG. D and FIG. 10B, it exits from the storage section 12N and enters the flat guide space 41 in the reproduction mechanism section 5 from the lower edge side through the fully open opening 57. When the cam gear 32 further rotates, the arm 46 rotates to its original position, and the disk 3N moves to the ninth position.
As shown in FIG.
supplied to After the disk 3N comes out of the storage rack 4, it is guided by both sides of the disk (not shown) on the side of the guide panel 39 and moves directly downward. The lower end of the disk is supported by a lower rib (not shown) of 39, and is held within the playback mechanism section 5 (guiding space 41) in a non-rolling state.

Here, since disk 3N moves under its own weight,
When transporting the disk 3N from the storage rack (storage section 12N) into the playback mechanism section 5, the disk catcher 61 only needs to support the outer peripheral edge 3a of the disk 3N, and no mechanism for gripping the disk is required. This becomes unnecessary, and the structure of the disk transport mechanism 27 becomes simple. . Furthermore, when the disk 3N is released from the disk stopper 14, the disk 3N does not fall due to its own weight, but the disk catcher 6
1 and lowers at an appropriate speed, which is preferable in terms of protecting the disk 3N.

At the final stage of rotation of the cam gear 35, the disc regenerator shift mechanism 26 and the disc clamp mechanism 30 operate, and the disc regenerator 25 moves in the direction of the arrow.
The disk clamper 72 moves (forwards) in _{the X 1 direction} and the arrow Clamped as shown in Figure C.

Subsequently, the disc reproducing machine 25 operates, the disc 3N rotates at high speed within the reproducing mechanism section 5, and the disc 3N is reproduced.

When the playback of the disk 3N is completed, the motor 38
starts up again and reverses, and the cam gear 35 moves to arrow B ₂
rotate in the direction.

When the cam gear 35 rotates in the opposite direction, the disk transport mechanism 2
7. The alignment mechanism 29, the disk player shift mechanism 26, and the disk clamp mechanism 30 simply operate in the opposite direction to that in the disk loading mode. Further, the disk guide mechanism 28 operates so as to be able to guide the disk as shown in FIG. 8C, and the disk separating mechanism 31 also operates as shown in FIG. 8F.

At the beginning of rotation of the cam gear 35, the disk regenerator 2
5 and the disk clamper 72 move away from each other, and the disk 3N is unclamped from the disk player 25 (see FIG. 10D)). Next, the arm 46 rotates clockwise, and the disk catcher 61 moves toward the outer peripheral edge 3 of the disk 3N.
Lock a and push up the disk 3N, Figure 9D
As shown in the figure, the disk regenerator 25 for disk 3N
Exhaust begins.

At the initial stage of ejecting the disk 3N, the disk guide mechanism 28 operates as shown in FIG. 8C, and the guide plates 51, 52 operate as shown in FIGS. 4, 6, and 10D.
As shown in FIG.
Hold 6. As a result, the disk guide mechanism 2
8, the inclined guide parts 51a and 52a are connected to the regeneration mechanism part 5.
The opening 57 is formed into an elongated opening with a width slightly larger than the thickness of the disk 3, and is positioned exactly below the disk storage portion 12N in a state in which the disk 3N to be ejected can be guided. .

In addition, the rotating arm assembly 74 in FIG.
The disk separator 73 is kicked by B- ₃ and rotated counterclockwise, and the disk separator 73 is slightly displaced in the direction of arrow _X2 and moved in the direction of arrow _Y2 to the position shown by the two-dot chain line. The disk separator 73 is then immediately returned to its original position by the spring 76 (see FIG. 8F). As shown in FIG.
It cuts in between disks 3N+ ₁ and 3N- ₁ on both sides of the disk. Therefore, disk 3N+ ₁
Even in the case where the discs 3N+ 1 and 3N- ₁ are slightly inclined and their lower ends are close to each other, narrowing the gap between the discs, the space between the discs 3N+ ₁ and 3N- ₁ , that is, the entrance of the disc storage section 12 A gap large enough for the disk 3N to enter is ensured.

As a result, the lower outer peripheral edge 3a is simply locked by the disk catcher 61, and the arrow
As shown in FIG. 10D, the disk 3N moving in the _Z1 direction has its upper end connected to inclined guide portions 51a and 52a.
is guided toward the opening 57 and exits from the reproduction mechanism section 5 through the narrow opening 57. disk 3
N escapes out of the reproduction mechanism section 5 while being guided by the opening 57, and the upper end moves toward the middle of the disks 3N+ ₁ and 3N- ₁ . Here, disk 3
Since a predetermined gap is formed between N+ ₁ and 3N- ₁ by the action of the beak-shaped portion 73a, the disk 3N
without colliding with disks 3N+ ₁ or 3N- ₁ , it smoothly enters between disks 3N+ ₁ and 3N- ₁ as shown in FIG. 10E, and starts to enter into the disk storage section 12N.

When the arm 46 rotates clockwise to the maximum, the disk 3N is completely ejected from the reproduction mechanism section 5 and returned to the original storage section 12N, as shown in FIGS. 9C and 9B. The operation of returning this disk to the original storage section 12N is also performed by the disk catcher 61 simply locking the outer peripheral edge 3a of the disk 3N and pushing it up. It is simpler than if you do it. When the disk 3N is stored in the storage portion 12N, the alignment plates 55 and 56 are lowered, the disk stopper 14 returns to the operating state, and the device 1
becomes the state shown in FIG. 9B.

When the cam gear 35 rotates further, the arm 46 starts rotating counterclockwise. Cam gear 3
5, the protrusion 35B- ₃ rotates to the original position detected by the microswitch 82 and stops, as shown in FIG. In this state, as shown in FIGS. 9A and 10A, the device 1 returns to the initial state in which the disk 3N is locked by the disk stopper 14 and stored and held in the original storage portion 12N. .

By repeating the above operations, the designated disks in the storage rack 4 are returned to the original storage section of the storage rack after playback, and are sequentially selected and played back.

Further, the disc 3 is not limited to a compact disc, but may also be applied to, for example, an optical video disc.

Next, positioning plates 55 and 56 which form the main part of the present invention
This and related mechanisms will be explained in more detail with reference to FIG. 11 and subsequent figures. Note that the alignment plates 55 and 56 arranged on the left and right sides and the mechanisms related thereto have similar configurations, and the alignment plate 56 on the right side in FIG. 2 will be described below.

In the initial state, as shown in FIGS. 11 and 12, the alignment plate 56 has a pin 90 supported at the tip of the connecting arm 65 on the lower side, and a pair of opposing rollers 68 on the upper side. .
The position is regulated within the narrow part 91a of the frame (consisting of ``b'') and is supported in a vertical position in a lowered position.

Rollers 68 and 69 are connected to brackets 92 and 93, respectively.
It is located at the top of the . The bracket 93 has notches on both sides of its lower part fitted into the holder member 94, is supported vertically along the outer surface near the top of the panel 39, and can be rotated in the directions of arrows _C1 and _C2 . It can be displaced. Similarly, the bracket 92 also has a holder member 95.
The panel 40 is fitted into the panel 40 and is supported vertically along the outer surface near the top of the panel 40, as indicated by the arrows D ₁ and D _{2 .}
It can be rotated in the direction. Each holder member 94, 95
are screwed to panels 39 and 40, respectively.
Further, the brackets 92 and 93 are biased in the directions of arrows C ₁ and D ₁ , respectively, by a coil spring 96 stretched between them, and the rollers 68 and 69 are close to each other.

Here, the position of the roller 68 is determined by the bracket 92.
The tip of the adjustment screw 97 screwed through the bracket 93 is in contact with the panel 40, and the roller 69 is positioned so that the tip of the adjustment screw 98 screwed through the bracket 93 is in contact with the panel 39. It is determined. The distance between the rollers 68 and 69 is adjusted to correspond to the thickness of the alignment plate 56.

The alignment plate 56 is pushed up by the counterclockwise rotation of the connecting arm 65 and moves upward in the direction of arrow _Z1 . At this time, the alignment plate 56 is guided by rollers 68 and 69 at the exit point from the regeneration mechanism section 5, that is, with the exit position determined by the rollers 68 and 69, the positioning plate 56 is placed above the regeneration mechanism section 5. stand out.

Here, for example, the playback mechanism section 5 has stopped at a position slightly beyond the planned stop position, and the alignment plate 56 has moved closer to the storage section 12N+ ₁ than the center of the storage section 12N, as shown in FIG. If the alignment plate 56 is biased, how can the alignment plate 56 be moved to the predetermined storage portion 1?
Regarding whether to enter 2N, see Figures 13 and 14.
This will be explained with reference to the figures.

When the alignment plate 56 protrudes upward, the tapered top portion 56a aligns with the storage portions 12N and 12N+ _1.
It collides with the tapered lower edge _10a of the partition blade 10 that separates the
direction, and the alignment plate 56 begins to enter the storage portion 12N as shown in FIG. In this state, the pin 90 is still in the narrow part 9 of the deformed hole 91.
Since it is guided by 1a, the alignment plate 5
6 is inclined with the top displaced to the right.

The alignment plate 56 further protrudes upward and the storage section 1
2N, the pin 90 slips out of the narrow part 91a of the deformed hole 91 and enters the wide part 91b, as shown in FIG _.
It becomes possible to displace in the X _two directions. Therefore, as the alignment plate 56 enters the storage section 12N, it is guided by the partition wings 10 on both sides, and its posture is corrected in the direction in which the lower end side is displaced in the direction of arrow _X1 , so that the positioning plate 56 follows the storage section 12N. So, storage section 1
To enter 2N smoothly and reliably.

When the alignment plate 56 is projected to the final position, the bracket 92 rotates in the direction of arrow _C2 , the roller 68 is pushed away in the direction of arrow _X1 , and the alignment plate 56 is moved along the center line of the storage section 12N. Thus, it is in a state where it hangs downward from the storage section 12N. The alignment plate 56 also presses the disk stopper 14 at its top, and the disk stopper 14 is released as shown in FIG. 9C.

The left alignment plate 55 also enters into the storage portion 12N in the same manner as the alignment plate 56 described above, and thereby becomes in a state of protruding directly below.

When returning the disk, the guide plates 51 and 52 are placed close to each other and the alignment plates 55 and 5 are placed close to each other as described above.
6 is sandwiched to form an elongated opening 57 (10th
(See Figures D and E). Here, since the alignment plates 55 and 56 on the left and right ends of the storage section 12N both hang down directly below the storage section 12N, rather than diagonally, the 11th
As shown in FIG. 14, the guide plates 51, 52
When the positioning plates 55 and 56 are sandwiched between the openings 57, the openings 57 are formed exactly below the storage portions 12N. As a result, when returning the disk, disk 3
passes through the opening 57 and protrudes from the reproduction mechanism section 5 at a position directly below the storage section 12N, so that the disk 3 is reliably stored within the storage section 12N without colliding with the partition blade 10.

In the above embodiment, one of the alignment plates 56 also has the function of releasing the disk stopper 14 as described above. Therefore, there is no need to provide a special mechanism such as a plunger for releasing the disk stopper 14, and the device becomes simpler.

Note that when the device 1 is actually assembled, both or only one of the alignment plates 55, 56 may be , as shown in FIG. 12, it is shifted from the center of the predetermined storage section. In this case, it is desirable to be able to adjust the positioning plates 55, 56 within the playback mechanism section 5 by displacing them in the directions of arrows _X1 and _X2 so that the top portions can accurately face the storage section 12N. In this embodiment, this adjustment is possible.

This adjustment will be explained below. As shown in FIG. 12, if the alignment plate 56 is offset from the center of the storage portion 12N in the direction of arrow _X2 , first turn the adjustment screw 97 in the screwing direction. This results in
As shown by the two-dot chain line in FIG. 15, the bracket 92 rotates in the direction of arrow C2 about the fitting part with the holder 95 against the spring 96, and the roller 68 rotates in the direction of arrow _C2 .
Displaced in the X ₁ direction. Next, turn the adjustment screw 98 in the loosening direction. As a result, the bracket 93 is rotated in the direction of arrow _D1 by the spring 96, and the roller 6
9 is displaced in the direction of arrow _X1 and pushes the alignment plate 56. As a result, the alignment plate 56 is held between the rollers 68 and 69 as shown by the two-dot chain line in FIG. 15, so that the top thereof accurately faces the storage portion 12N.

In this adjusted state, when the alignment plate 56 protrudes, it reliably and smoothly enters the storage portion 12N.

As described above, the alignment plates 55 and 56 can be displaced in the direction of the arrangement of the storage sections by screwing in one adjustment screw and loosening the other adjustment screw, depending on the direction of displacement with respect to the predetermined storage section. Then, the position is adjusted so that the top part faces the center of the predetermined storage part. Note that the alignment plates 55, 55 are adjusted independently.

Effects As mentioned above, the recording disk automatic selection and playback device of the present invention has the following features.

Even if the alignment member is slightly offset from the center of the storage unit, the position of the alignment member is corrected in the direction in which the storage units are lined up during the process of entering the storage unit, and the alignment member can smoothly enter the specified position in the storage unit. . That is, a certain degree of assembly error can be tolerated for the device.

When the alignment member enters the storage section normally, the recording disk ejection port is accurately positioned directly below the storage section, and the recording disk ejected from the playback mechanism through the recording disk ejection port is placed in the specified position. It will be returned to you after it enters the storage compartment securely.

Even when recording disks are mounted at a high density by setting the pitch of the arrangement of the recording disk storage sections to be extremely narrow, the operation of returning the recording disks to the original storage section can be performed reliably and stably.
