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 record discs are stored side by side in a storage rack, facing each other, and the player body moves along the side of the storage rack to play the designated record disc. The arm member rotates to take out the specified record and attach it to the player body.
The record disc is played back, and after the playback is finished, the arm member rotates in the opposite direction to remove the record disc from the player body and return it to the original storage section in the storage rack.

Problems to be Solved by the Invention The record enters between the record discs stored in the storage units on both sides of the original storage unit, and is returned to the original storage unit. Furthermore, regarding the storage condition of records in the storage rack, since the records are stored in the storage compartment with a certain amount of room, the records may be tilted slightly inside the storage compartment. . Here, if the records stored in the storage compartments on both sides of the original storage compartment are tilted in the direction of approaching each other, the records on both sides are stored in the storage compartments on both sides of the original storage compartment. It looks like a part of the record entrance, and the record entrance is unnecessarily narrowed by the record discs on both sides. In this situation, the record to be returned collides with the records on both sides at the entrance of the original storage section, and the operation of returning the record is restricted midway, resulting in the record not being returned. This may cause an accident. This accident is particularly likely to occur when records are stored in a storage rack with narrow pitches and high density.

The object of the present invention is to provide an automatic recording disk selection and playback device that solves the above-mentioned problems.

Means for Solving the Problems FIG. 15 shows a schematic configuration of the present invention. In the figure, 1
00 _N-1 , 100 _N , and 100 _N+1 are recording disks.

_100N is a recording disk that is being played back, and is returned to the storage unit _101N after playback.

Figure A shows a state in which the recording disk _100N is being reproduced. This recording disc of 100 _N has a storage part of 10 after playback.
1 to be returned to _N.

The recording disks 100 _N-1 and 100 _N+1 are the storage sections 101 _N-1 and 10 on both sides of the storage section 101 _N among the storage sections formed side by side in the recording disk storage rack, respectively.
1 Stored within _N+1 .

Reference numeral 102 denotes a gap forming member, the tip of which is wedge-shaped, and the width W of the main body portion is sufficiently larger than the thickness t of the recording disk.

When returning the recording disk _100N , the gap forming member 102 moves upward and temporarily enters between the recording disks 100N _-1 and 100N ₊₁ , and the recording Disk 100 _N-1 100 _N+1 is V
If the shape is slanted, push it aside to widen the gap and then get out.

The gap forming member 102 is sufficiently lowered to reach a position where it does not interfere with the insertion and removal of the disk.

In this state, the recording disc _100N is returned into the storage unit _101N , as shown in FIG.

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. Further, a negative 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. Further, there are no partition wings in the center of the storage rack 4, and the space is continuous in the longitudinal direction. Therefore, the storage rack 4 is easy to mold and lightweight, and the disk surface of the disks stored therein can be effectively prevented from being scratched.

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.

Since the arm 46, which will be described later, does not pass through the storage rack 4, there is no need to provide a gap between every other disk that is wide enough for the arm to pass through. 3 are lined up with a small pitch. In this embodiment, the thickness of each partition blade 10 is approximately 1 mm, the pitch of the partition blades 10 is approximately 3 mm, and the disks 3 are tightly housed in a narrow pitch of approximately 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, and a disk separating mechanism 31 that is the main part of the present invention and separates the disks on both sides of the storage section to which the disk is returned when returning the disk to the storage rack.
Each mechanism is configured to operate in conjunction with the rotation of the cam gear 35 shown in FIGS. 7A to C. The cam gear 35 is shown in Fig. 7C.
The cam surface 35A shown in FIG. 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 arrows D, respectively.
It is a view seen from the E direction. 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 substantially arc-shaped disk transport 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 includes alignment plates 55 and 56 provided on both ends of the opening 57 so as to be displaceable in the directions of arrows _Z1 and _Z2 , and a cam groove 35A- ₃ of the cam surface 35A.
The rotating arms 62, 63 are guided by the rotating arms 62, 63, and the connecting arms 64, 65 connect the rotating arms 62, 63 to the alignment plates 55, 56. In the initial state, the alignment plates 55 and 56 are displaced in the _two directions of arrow Z and inserted into the regeneration mechanism section 5, and the cam gear 3
5 rotates, they simultaneously move in the direction of arrow _Z1 via the rotating arms 62, 63 and connecting arms 64, 65, protrude 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 .

The disk separating mechanism 31, as shown in FIG. 3, FIG. 6, and FIGS. 11 to 13,
It consists of a disk separator 73 on the guide plate 51, and a rotating arm assembly 74 that is kicked and rotated by the protrusion 35B- ₃ of the cam surface 35B and displaces the disk separator 73 in the direction of arrow _Y1 . When the disk separator 73 moves in the direction of arrow _Y1 , the tapered beak portion 73a enters the vicinity of the lower edge of the adjacent disks 3 and forcibly separates the adjacent disks 3, thereby creating a storage rack. 4 to form a path for the disk to be returned. The thickness of the beak 73a (2 mm) is the thickness of the disk 3 (1.2 mm).
It is set somewhat larger than that. Note that the disk separator 73 holds the pins 73c and 73d with a holding plate 75.
It can be displaced by being guided by bent long holes 75a and 75b, and is normally moved in the direction of arrow _Y2 by a spring 76. Further, the rotating arm assembly 74 has first and second arms 91 and 92 that are commonly pivotally supported on a shaft 90 on the outer panel 36, and pivotally supported on a shaft 93 on the second arm 92. The third
an arm 94, a spring 95 stretched between the first and second arms, and a spring 96 stretched between the second and third arms. Pushed by the hanging leg portion 73b and locked by the stopper pin 97, the third
As shown in the figure and FIG. 11A, it is rotating clockwise. The first arm 91 is an arm that is kicked by the protrusion 35B- ₃ of the cam gear 35, and due to the bent portion 91a, the first arm 91 is rotated clockwise toward the second arm 92.
The second arm 92 is rotated in the counterclockwise direction independently of the second arm 92 . Further, the third arm 94 is an arm that pushes the hanging leg portion 73b in the direction of arrow _Y1 , and due to the bending portion 94a, the counterclockwise rotation relative to the second arm 92 is not possible as shown in FIGS. 3 and 11A. The clockwise rotation is restricted by a spring 96. With this configuration, as will be described later, the arrow of the cam gear 35
B The first arm 91 touches the protrusion 35B while rotating in _one direction.
- when kicked by ₃ , the first arm 91
When the first arm 91 is kicked by the protrusion 35B- ₃ while the cam gear 35 is rotating in the _two directions of the arrow B, the second arm 92 and the third arm 94 do not rotate. Second and third arms 92,9
4 also rotates counterclockwise integrally with the first arm 91.

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 immediately below and opposite to the disk 3 _N in the disk storage section 12 _N 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 so that the disk _3N is moved as shown by the two-dot chain line (FIG. 9B).
(as shown by the solid line), lift it up a little so that it is above the disk stopper 14. Also, the rotating arms 62, 6
3 rotates counterclockwise and clockwise, respectively, and the alignment plates 55 and 56 move and rise in the direction of arrow _Z1 (see FIG. 8B), and the storage section _12N in the storage rack 4 is moved upward. In other words, it enters into the gap between adjacent partition wings 10 forming the storage section _12N . Further, 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. As a result, the device 1 is
The state shown in is reached.

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 3 _N is floating above the disc stopper 14, the weight of the disc 3 _N does not act as a load when the disc stopper 14 rotates in the unlocking direction, and the disc retainer of the disc stopper 14 The release action is 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 the 9th disk
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 35 further rotates, the arm 46 rotates to its original position, and the disc _3N moves to the ninth position.
As shown in FIG.
is supplied to After the disk 3 _N comes out of the storage rack 4, it is guided by both side ribs (not shown) on the guide panel 39 side and moves directly downward, and is further guided when being supplied to the playback mechanism section 5. The lower end of the disk is supported by a lower rib (not shown) of the panel 39, and is held within the playback mechanism section 5 (guide space 41) without rolling.

Here, since disk 3 _N moves by 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 periphery 3a of the disk _3N , and the disk catcher 61 only needs to support the outer periphery 3a of the disk 3N. This eliminates the need for such a mechanism, and the structure of the disk transport mechanism 27 becomes simple. Furthermore, when the disk _3N is released from the disk stopper 14, it does not fall due to its own weight, but is supported by the disk catcher 61 and descends at an appropriate speed, which protects the disk _3N . It is also preferable.

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 It is clamped as shown in Figure 10C.

It should be noted that the projection 3
5B- ₃ kicks the first arm 91, but at this time, only the first arm 91 rotates with the tension of the spring 95, as shown by the two-dot chain line in FIG. Arm 92 does not rotate. For this reason,
The disk separator 73 does not move and remains at its original position. Here, the original position of _the disk separator 73 is as shown in FIG. 6 and _FIG . It's more out of place.
The fact that the beak-shaped portion 73a is out of the opening 57 in the direction of arrow _X1 means that the beak-shaped portion 73a is out of the path of movement of the disk 3 that is supplied from the storage rack 4 to the playback mechanism section 5. Therefore, the disk 3 is supplied to the playback mechanism section 5 without colliding with the disk separator 73.

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

When the playback of 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 regenerator 25 (see FIG. 10D).
Next, the arm 46 rotates clockwise, and the disk catcher 61 locks the outer peripheral edge 3a of the disk _3N to push up the disk _3N , and as shown in FIG. 9D, the disk regenerator 25 of the 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.
In a state where it is possible to guide the disk 3 _N that is being ejected further,
In addition, 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 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. 10D and FIG. 14B, the beak-shaped portion 73a of the disk separator 73 connects the disks 3 _N+1 and 3 _N-1 on both sides of the disk 3 _N at a position directly above the opening 57.
Intervene between them and enter. For this reason, the 14th
As shown in Figure A, even when disks 3 _N+1 and 3 _N-1 are slightly inclined and their lower ends are close to each other, narrowing the gap between the disks, disk 3
A gap is secured between _N+1 and 3 _N-1 , that is, a gap large enough for the disk 3 _N to enter the entrance of the disk storage section 12 _N.

Rotating arm assembly 74 and disk separator 7
To explain the operation of step 3 in detail, see FIG. 11B.
As shown in FIG. 2, when the first arm 91 is kicked by the protrusion 35B- ₃ moving in the direction of arrow _B2 and rotates counterclockwise, the second arm 92 is integrally moved with the first arm 91. direction, and the pivot arm assembly 74 pivots counterclockwise. When the rotating arm assembly 74 rotates, the hanging leg portion 73b of the disk separator 73 is pushed by the third arm 94 and is displaced in the direction of arrow _Y1 against the spring 76. As shown in FIG. 13B, the disk separator 73 is guided by elongated holes 75a and 75b and is displaced in the direction of _arrow
Move in the direction of arrow Y ₁ at the position directly above the disk storage area 12 _N on both sides of the disk storage area 12 _N to which the disk 3 _N is returned, as shown in FIG. 14B.
₊₁ , 12 Disk 3 stored in _{N-1 N+1} ,
3N _-1 and expands them as the case may be, forming a gap 98 wider than the thickness of the disk _3N at the entrance of the disk storage section _12N .

When the disk separator 73 returns, the 13th
As shown in Figures A and 14C, the beak 73a retreats in the direction of arrow _X1 from the path of the returned disk _3N , and the disk _3N moves upward without being obstructed by the beak 73a. will be returned.

As shown in FIG. 10D, the disk 3 _N moves in the direction of arrow Z ₁ with its lower outer peripheral edge 3 a simply locked by the disk catcher 61.
The upper end side is guided by the inclined guide portions 51a and 52a toward the opening 57, and exits from the reproduction mechanism section 5 through the narrow opening 57. Disc 3 _N is opening 57
Walk out of the regeneration mechanism section 5 while being guided by
The upper end moves toward the middle between disks 3 _N+1 and 3 _N-1 . Here, since a predetermined gap 98 is formed between the disks 3 _N+1 and 3 _N-1 by the action of the beak-shaped portion 73a, the disk 3 _N is connected to the disk 3 _N+1 or 3 _N-1. As shown in FIG. 10E, it smoothly enters between the disks 3 _N+1 and 3 _N-1 without colliding with the other disks, and begins to enter the disk storage section 12 _N.

When the arm 46 rotates clockwise to the maximum, the disk _3N is completely ejected from the regeneration mechanism section 5 and returned to the original storage section _12N , as shown in FIGS. 9C and B and FIG. 14C. . 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. This is easier than when holding a . When the disk _3N is stored in the storage section _12N , the alignment plates 55, 56
is lowered, the disk stopper 14 returns to its operating state, and the apparatus 1 enters 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 is in 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 . Return.

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.

In the above embodiment, the disk separator 73 moves sideways so as not to obstruct the insertion and removal of the disk, but the present invention is not limited to this, and the disk separator 73 may be moved down sufficiently so as not to obstruct the insertion and removal of the disk. You can also do that.

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

Effects As described above, according to the recording disk automatic selection and playback device of the present invention, the recording disks in the storage sections on both sides of the original storage section to which the recording disks are returned are tilted and the entrance of the original storage section is tilted. Even if you are narrowing down the
When returning a recording disk, the space between the two adjacent recording disks is expanded to form a gap that is greater than the thickness of the returned recording disk, so the returned recording disk collides with the two adjacent recording disks. To ensure that a recording disk enters into an original storage part and is stored there without causing any trouble, and that a recording disc is surely stored and returned to the original storage part no matter what state the recording disc in the storage rack is in. The present invention has the advantage that it is particularly effective when applied to a device incorporating a storage rack for arranging recording disks at a narrow pitch and storing them at high density.
