Description

[Detailed description of the invention] The present invention relates to an automatic recording disk selection and playback device, and in particular, a pair of positioning members for determining the position of the recording disk ejection port of the playback mechanism section are provided outside the path of the recording disk, and one positioning member is provided outside the path of the recording disk. It is an object of the present invention to provide a compact and simplified recording disc automatic selection and playback device in which a member releases the holding of the recording disc while positioning an ejection port.

Conventionally, a so-called joke box, which is an automatic record disc selection and playback device, stores a large number of record discs in a storage rack in a row facing each other, and moves a player section to a designated mounting position of the record disc. It had a configuration including a positioning member for stopping and an arm member for gripping a designated record and transporting it onto the turntable of the player section. Therefore, the conventional recording disk automatic selection and playback device has a complicated structure and a large number of parts.
The drawback was that it was difficult to miniaturize the device. The present invention eliminates the above-mentioned drawbacks, and an embodiment thereof will be described below with reference to the drawings.

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. Disk stopper (retention mechanism)
14 is supported by a shaft 15 outside the path through which the disk 3 moves up and down, and is disposed in the space 10a between adjacent partition blades 10, and is biased counterclockwise by a spring 16 to normally It rotates in the same direction and protrudes into the disk storage section 12. Also, both the ceiling and the bottom of the storage rack 4 have openings 17,
It is listed as 18.

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 disks are surely separated from the disks 3 on both sides by partition wings 10 and are stored in the storage rack 4 in a state in which the inclination is restricted and does not contact the disks at both ends, aligned in a vertical posture facing each other. 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, and the disk 3 are lined up with a small pitch. 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 at both ends, 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 .

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 a positioning mechanism 29 that aligns the disk guide mechanism with a predetermined disk storage section 12 of the storage rack. , a disk clamping mechanism 30 for clamping the disk during playback, and a disk separating mechanism 31 for separating the disks on both sides of the storage section into which the disk is returned when returning the disk to the storage rack. It is configured to operate in conjunction with the rotation of one cam gear 35 shown in Figures A to C. The cam gear 35 has a cam surface 35 shown in FIG. 7C.
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 structure 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,

Regarding the lever 60, the arms on both sides have protrusions 51, respectively.
d, facing 52c. As a result, when one guide plate 51 is displaced in the arrow X ₁ and X ₂ directions,
The other guide plate 5 via the left and right levers 59, 60
2 is displaced in the directions of arrows X ₂ and X ₁ , that is, symmetrically with respect to the guide plate 51. The pins 95 and 96 are fixed on brackets 97 and 98 whose positions are adjustable, respectively, and each bracket 97 and 98 is attached to the panel with the center position of each lever 59 and 60 adjusted during rotation. It is screwed onto the 99. The brackets 97, 98 and the screws for fixing them are both arranged on the upper surface side of the panel 99, and this adjustment work is easy. Further, the levers 59, 60 and the springs 53, 54 are arranged at positions left and right away from the opening 57 so as not to interfere with the movement of the disk.

The positioning mechanism 29 includes positioning plates 55 and 56 provided at 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.

Note that the alignment plates 55, 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. 16 and 17, the alignment plate 56 has a pin 100 supported at the tip of a connecting arm 65 on the lower side, and a pair of opposing rollers 68 on the upper side. ,69

The position is regulated within the narrow part 101a of the holder, and the holder is supported in a vertical position in a lowered position.

Rollers 68 and 96 are connected to brackets 102 and 1, respectively.
It is provided at the upper end of 03. The bracket 103 is
The notches on both sides of the lower part are fitted into the holder member 104, and the panel 39 is supported vertically along the outer surface near the top of the panel 39, and can be rotated in the directions of arrows D ₁ and D ₂ . Similarly, the bracket 102 is also fitted into the holder member 105 and supported vertically along the outer surface near the top of the panel 40.
It can be rotated in the directions of arrows C ₁ and C ₂ . Each holder member 104, 105 is screwed to a panel 39, 40, respectively. Also, brackets 102, 10
3 are biased in the directions of arrows C ₁ and D ₁ , respectively, by a coil spring 106 stretched between them, and the rollers 68 and 69 are close to each other.

Here, the position of the roller 68 is the same as that of the bracket 10.
The tip of the adjustment screw 107 screwed through the panel 40 is set in contact with the panel 40, and the roller 69
The position of is determined by the tip of the adjustment screw 108 screwed through the bracket 103 coming into contact with the panel 39. The distance between both rollers 68 and 69 is
The dimensions are 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 56 and moves upward in the direction of arrow _Z1 . At this time, the positioning plate 56 is guided by the rollers 68 and 69 at the exit point from the regeneration mechanism section 5, that is, the positioning plate 56 is moved upwardly from the regeneration mechanism section 5 with the exit position determined by the rollers 68 and 69. stand out.

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;

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 configured.

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.

Among the early devices, device 1 is shown in Figures 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 operating 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 so that the disk 3N is moved as shown by the two-dot chain line (shown by the solid line in FIG. 9B). ) Lift it up a little and let it float 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. enters into the spaces 10a and 10b.

When the alignment plate 55 protrudes upward, the tapered top portion 56a aligns with the storage portions 12N and 12N+ _1.
It collides with the tapered lower edge _10c of the partition blade 10 that separates the
The alignment plate 56 is displaced in the direction of the storage section 12N.
The vehicle begins to enter the space 10N outside of the vehicle. In this state, since the pin 100 is also guided by the narrow portion 101a of the deformed hole 101, the alignment plate 56 is tilted with its top portion displaced to the right.

The alignment plate 56 further protrudes upward to open the space 10.
When the pin 100 further enters into N, the pin 100 slips out of the narrow part 101a of the deformed hole 101 and enters the wide part _101b , as shown in _FIG . becomes. Therefore, as the alignment plate 56 enters the space 10N, it is guided by the partition wings 10, 10 on both sides, and its posture is corrected in a direction in which the lower end side is displaced in the direction of arrow _X1 , and the alignment plate 56 moves along the storage portion 12N. state, and enters the space 10N smoothly and reliably.

With the alignment plate 56 protruding to the final position, the bracket 102 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 in a state of hanging down from the storage section 12N along the center line of the storage section 12N. Further, the alignment plate 56 pushes up the disk stopper 14 from below at the top, and the disk stopper 14 rotates clockwise against the spring 16 as shown by the two-dot chain line in FIG. 2 and C in FIG. do.

Therefore, due to the upward movement of the alignment plate 56, the disk stopper 14 rotates from the disk holding position to release the holding of the disk 3N, and also to the avoidance position (2 in FIG. 2) out of the vertical movement space of the disk 3N. (indicated by the dotted chain line), and disk 3
This allows installation and movement of N to the playback mechanism 5 and return movement after playback output. 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).

Similarly to the above-mentioned alignment plate 56, the left alignment plate 55 simultaneously moves upward and enters the space 10b outside the storage portion 12N.
In the step of feeding the disks in the storage rack 4 into the regeneration mechanism section 5 (the step in which the cam gear 35 rotates in the direction of arrow _B1 ), the pin 94 is inserted into the inner cam groove 35B.
− ₁ relatively guided by a → a → b in Figure 7 A
→ c → d, dips at point d, moves to outer circumference side cam groove 35B- _1b , and moves to point e. 12th
The figure shows a state in which the pin 31 is guided at a point c in the inner cam groove 35B- _1a .
The expansion lever 58 is rotated counterclockwise in the lowered position, and the guide plate 51 is displaced in the direction of the arrow _X1 to be spaced from the center line CL by a distance _l1 into the disk storage portion 12N. The guide plate 52 is pushed by the levers 59, 60 on the left and right protrusions 52a, 52b at the same time, and is smoothly displaced in the direction of the arrow _X2 against the springs 53, 54, and is spaced by a distance l ₁ from the center line CL. ing.
As a result, each inclined guide plate 5 of the guide plates 51 and 52
The upper line portions 51a- ₁ and 52a- ₂ of 1a and 52a (which face each other and form the edge of the opening 57) have a dimension l ₁
and _l2 , and the width of the opening 57 is _{W1 .}
It is at almost full throttle.

As a result, the device 1 has the disk 3 and the guide plate 5
The state shown in FIG. 9B is reached, in which the liquid is supplied into the regeneration mechanism section 5 through the opening 57 without colliding with the particles 1 and 52.

When the cam gear 35 rotates further, the alignment plate 5
5 and 56 are spaces 10b and 1 on both sides of the storage section 12N.
It further enters into 0a, and the plate combination plates 55 and 56 become in a state where they can be regarded as members protruding directly below both ends of the storage portion 12N. Therefore, in this state, the alignment plates 55 and 56 can serve to position the guide plates 51 and 52 so that they coincide with the storage portion 12N when the disk is returned, which will be described later.

Further, the lever 50 moves in the direction of arrow _Y2 , and the disk carrying arm 46 begins to rotate 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 as shown in FIG. 9(D) and FIG. It enters into the flat guide space 41 in the reproduction mechanism section 5 through the opening 57 which is in a fully open state. When the cam gear 32 further rotates, the arm 46 rotates to its original position, and the disk 3N slips out of the storage rack 4 and completely enters the regeneration mechanism section 5, as shown in FIG. 9E, and is regenerated. It is supplied to the mechanism section 5. After the disk 3N has come out of the storage rack 4, it is guided by both side ribs (not shown) on the guide panel 36 side and moves directly downward, and when it is supplied to the playback mechanism section 5, it is further moved by the guide panel 36. The lower end of the disk is supported by the lower rib (not shown) of 39, and the playback mechanism section 5 (guiding space 4
1) held within.

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 positioning 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 locks the outer peripheral edge 3a of the disk 3N and pushes up the disk 3N, causing the disk 3N to move out of the disk reproducing machine 25 as shown in FIG. Ejection begins.

In the step of ejecting the disk 3 in the reproducing mechanism section 5 from the reproducing mechanism section 5 and returning it to the original storage section 12N of the storage rack 4 (the step in which the cam gear 35 rotates in the _two directions of arrow B), the pin 94 As shown in FIG. 7A, it is relatively guided by the outer cam groove 35B- ₁ b and moves in the order of e → f → g → h → i → j, and drops down at point j and moves back into the inner cam groove 35B- _1a , and moves along the inner cam groove 35B- _1a to the original point a.

When the pin 94 is guided by the outer cam groove 35B- _1b , the expansion lever 58 moves upward in the direction of arrow _Z1 against the spring 93, and the arm portion 58a moves into the slit 51b.
stand out more. When the pin 94 is guided beyond point f, it gradually enters the deep part of the cam groove 35B- _1b , and the expansion lever 58 is rotated clockwise by the spring 93. According to the rotation of the expansion lever 58 at this time, the guide plate 51 moves in the direction of arrow _X2 , that is, the center line.
Displaced in the direction approaching CL. In relation to the above displacement of the guide plate 51, the lever 59 rotates clockwise, the lever 60 rotates counterclockwise, and the guide plate 52 rotates in the direction of the arrow.
Displaced in the X ₁ direction.

In the state where the pin 94 is guided in the deep groove between points gh, the expansion lever 58 is rotated up to the vertical position as shown in FIG. 14, and the guide plates 51, 52 As shown in FIG. 6, the upper edges 51a- ₁ and 52a- ₂ collide with and sandwich the alignment plates 55 and 56, and the opening 57 is placed between the alignment plates 55 and 56. It becomes a narrow opening (width dimension W ₂ ) equal to the plate thickness of 55 and 56,
It is formed right below the storage section 12N.

As a result, the upper edge side of the disk 3N ejected from the reproducing mechanism section 5 is provided with an inclined guide plate 5 having an inverted V shape.
1a and 52a, and is guided by the upper edges 51a- ₁ and 52a- ₂ to come out of the opening 57 (that is, to come out of the regeneration mechanism part 5 at a position directly below the storage part 12N), and then to be stored. Facing the section 12N, enter the disk storage section 12N from below.
Be sure to start entering the area.

After the upper part of the disk 3N enters into the disk storage part 12N, the guidance by the upper edges 51a- ₁ and 52a- ₂ is not necessarily necessary, but rather the opposing surfaces of the upper edges 51a- ₁ and 52a- ₂ Since this is undesirable as it will scratch the signal recording surface of the returned disk 3N, the opening 57 is opened after approximately the upper half of the disk 3N enters the disk storage section 12N.

That is, when the pin 94 passes the point i, the expansion lever 58 rotates counterclockwise at the upward movement position as shown in FIG. 15, and the guide plate 51 is displaced in the direction of arrow _X1 . When the guide plate 51 is displaced as described above, the lever 59 is rotated counterclockwise and the lever 60 is rotated clockwise, and the guide plate 52 is pushed by the left and right protrusions 52b and 52c by the levers 59 and 60, so that the guide plate 52 springs. 5
3, 54 and is displaced in the direction of arrow _X2 . Here, the guide plate 52 is pushed at the left and right sides at the same time, so it is smoothly displaced without being pulled. By displacing the guide plates 51 and 52 as described above, the opening 57 is fully opened as shown in FIG. 15, and subsequent disk return operations can be performed without any risk of damaging the disk recording surface.

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 _Y1 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 portion 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 section 12N, the alignment plates 55 and 56 are lowered, the disk stopper 14 is returned 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.

In the above embodiment, a compact disk was used as the disk, but the present invention is not limited to this, and may be applied to, for example, an optical video disk or a record disc.

As described above, the recording disc automatic selection and playback device according to the present invention includes a plurality of recording disc storage units that store each of a plurality of recording discs, a holding mechanism that holds each of the recording discs in a storage position of the storage unit, A playback mechanism that moves along the recording disk storage section, stops at a position facing the designated storage section, is supplied with the recording disk in the storage section, and plays it back; and a record that is returned from the playback mechanism to the storage section. In an automatic recording disc selection and playback device comprising a pair of discharge port forming members forming a recording disc discharge port through which the disc passes, the recording disc is provided outside a passage through which the recording disc moves between a storage section and a playback mechanism section. , a pair of positioning members that are fitted between the pair of discharge port forming members to position the discharge port formed by the discharge port forming member to face the storage section in which the recording disk is to be returned; Since one of the members is configured to be released from the holding mechanism of the recording disc in the designated storage section, the positioning member does not interfere with mounting and return movement of the designated recording disc, and the recording disc can be moved. The space outside the main passage can be used effectively, and the positioning member on one side accurately guides the ejection port to the designated recording disc storage area.
It also serves to release the holding of the disk stored in the storage section, allowing for a simple configuration with a small number of parts, and therefore releasing the holding of the recording disk between the plurality of recording disks stored in the recording disk storage section. Since there is no need to provide any parts or space for storage, each recording disc can be stored closely together, making it possible to downsize the device and store a larger number of recording discs within a limited storage space. It has features such as being able to store items in a high density.
