Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic recording disk selection and playback device that selects and plays back 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 that holds the record stops at the opposing position, rotates, takes out the specified record, attaches it to the player, plays the record, and after the playback is finished, the arm member rotates in the opposite direction. The record disc is rotated in the direction to remove the record from the player body and return it to its original position in the storage rack.

Problems to be Solved by the Invention In this device, since the player body is placed on the side of the storage rack, the arm member that holds the outer periphery of the record moves through the rack. It is necessary to provide a space between adjacent record discs in the storage rack that is large enough for the arm member to pass through. For this reason, the pitch of the records stored in the storage rack becomes rough, and the number of records that can be stored in the storage rack of a predetermined length decreases.In other words, the record storage capacity of the storage rack decreases, and vice versa. If the number of records to be stored is fixed, the length of the storage rack becomes long and the device becomes large, making it difficult to downsize the device. Furthermore, since the record disc is held at its outer periphery by an arm member and moved along a substantially horizontal arc between the storage rack and the player body, the apparatus is mechanically complex.

Means for Solving the Problems The present invention has been made in view of the above-mentioned problems, and includes a method of storing recording disks in a vertical position, partitioning them with a plurality of partition wings, and aligning a plurality of recording disks in a horizontal direction. and a plurality of recording disc storage units arranged in such a manner that they can freely approach and separate from the outer periphery of the recording disc between the adjacent partition blades, and are in contact with the outer periphery of the recording disc to prevent the recording disc from moving downward. a plurality of disk stopper members for locking the plurality of disks; a reproducing mechanism section disposed below the plurality of recording disk storage sections and having a reproducing machine for reproducing the recording disks carried in from above; and the reproducing mechanism section. a movement-stop mechanism that moves the disc along the plurality of recording disc storage units and stops it at a position facing the specified desired recording disc; a locking release member that, when facing a recording disk, displaces the disk stopper member that locks the recording disk so as to release the lock from the desired recording disk, thereby allowing the desired recording disk to move downward; and, provided in the reproducing mechanism section, the reproducing mechanism section moves downward and retreats from the recording disk before reproducing the recording disk, and when the reproducing mechanism section performs a reproducing operation facing the desired recording disk, The disk stopper member is moved upward to support the lower outer peripheral edge of the desired recording disk before the disk stopper member is released from the lock, and the supported desired recording disk is vertically moved after the disk stopper member is released from the lock. The desired recording disk is transported downward in this posture and carried into the playback machine, and after the playback is finished, the desired recording disk is transported from the playback machine to the recording disk storage section above while supporting the lower outer peripheral edge thereof while maintaining a vertical posture. An object of the present invention is to provide an automatic recording disk selection and playback device characterized by comprising a disk transporting member for returning the disk.

Embodiment FIG. 1 shows a compact disc automatic selection and reproduction apparatus 1 which is an embodiment of the recording disk automatic selection and reproduction apparatus 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 chamber 12, and the storage rack 4
has a structure in which a large number, for example, 100 disk storage chambers 12 are closely aligned in the longitudinal direction.
The 100 disk storage chambers 12 are sequentially numbered. Also, one slit 13 is formed corresponding to each disk storage chamber 12. Furthermore,
1 disk stopper for each disk storage chamber 12
4 is provided. The disk stopper 14 is connected to the shaft 15
The disk storage chamber 12
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 chamber 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 chamber 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 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 for shifting the disk playback machine, and a rack 4 for playback while simply supporting the disc. Disk transport mechanism 2 that transports between the mechanism section 5
7. A disk guide mechanism 28 that guides the disk ejected from the playback mechanism, an alignment mechanism 29 that aligns the disk guide mechanism with a predetermined disk storage chamber 12 of the storage rack, and a disk clamp mechanism 30 that clamps the disk during playback. When the disk is returned to the storage rack, it is provided with a disk separating mechanism 31, etc., which separates the disks on both sides of the storage chamber into which the disk is returned, and each mechanism is configured to rotate one cam gear 35 shown in FIGS. 7A to C. It is configured to operate in conjunction with each other.
The cam gear 35 is mounted on the shaft 37 at a substantially central position inside the outer panel 36 of the regeneration mechanism section 5, with the cam surface 35A shown in FIG. 7C facing outward and the cam surface 35B shown in FIG. It is supported and rotated by a motor 38. Figure 2 shows cam gear 35

5 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 to face 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. The cam 35A _-1 on the cam surface 35A side acts on the roller 44 in the middle of the shift arm 43, and 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.

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).
) is guided by the cam groove 35A _-2 of the cam surface 35A and moves in the directions of arrows _Y1 and _Y2 .
0 and more. 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 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 in the _direction of arrow It can be displaced to Information board 51
When the levers 59 and 6 on both sides are displaced in this way,
0, another guide plate 52 is displaced 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 Z ₁ and Z ₂ , and rotation guided by the cam groove 35A _-3 of the cam surface 35A. It consists of arms 62, 63 and connecting arms 64, 65 that connect the rotating arms 62, 63 and the alignment plates 55, 56. Alignment plate 5
5 and 56 are displaced in _{the two} directions of arrow Z and inserted into the regeneration mechanism section 5 in the initial state, and the cam gear 35
When it rotates, it simultaneously moves in the direction of arrow _Z1 via the rotating arms 62, 63 and the connecting arms 64, 65,
It protrudes from the reproduction mechanism section 5 and enters into 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 35 on the cam surface 35B.
It consists of a rotating arm assembly 74 that is kicked by B _-3 and rotates to displace 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 _.
The arm assembly itself is bent and does not rotate when kicked by the arrow B, and rotates counterclockwise when kicked by the protrusion 35B _-3 while the cam gear 35 is rotating in _{the two} directions of arrow B. It has been done.

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 opposite to the disk 3 _N in the disk storage chamber 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 peripheral edge 3a of the disk _3N in the storage chamber _12N of the rack ₄ , and 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 chamber _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 chamber _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 chamber _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 chamber _12N . Therefore, in this state, each alignment plate 55, 56 moves the guide plates 51, 52 to the storage chamber _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 chamber _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 rotates further, 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 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 disc _3N from the storage rack (storage chamber _12N ) into the playback mechanism section 5, the disc catcher 61 only needs to support the outer periphery 3a of the disc _3N , and the disc catcher 61 only needs to support the outer periphery 3a of the disc 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.

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 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 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 chamber _12N .

In addition, the rotating arm assembly 74 in FIG.
The disc 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, the beak-shaped portion 73a of the disk separator 73 is inserted between 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. enter in. Therefore, even if the 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, the disks 3 _N+1 and 3 _{N- 1} , that is, a gap sufficient for the disk _3N to enter the entrance of the disk storage chamber 12 is secured.

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 3 _N 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 between the disks 3 _N+1 and 3 _N-1 . Here, disk 3 _N+1
Since a predetermined gap is formed between the disks 3N _{-1 and} 3N-1 by the action of the beak-shaped portion 73a, the disk _3N does not collide with the 10th disk 3N ₊₁ or 3N _-1 .
As shown in Figure E, it smoothly enters between the disks 3 _N+1 and 3 _N-1 and begins to enter the disk storage chamber 12 _N.

When the arm 46 rotates clockwise to the maximum, the disk _3N is completely ejected from the playback mechanism 5 and returned to the original storage chamber _12N , as shown in FIGS. 9C and 9B. The operation of returning this disk to the original storage chamber _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 chamber _12N , the alignment plates 55 and 56 are lowered, the disk stopper 14 is returned to its operating state, and the apparatus 1 is placed in 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, the device 1 is shown in FIG.
Then, as shown in FIG. 10A, the disk _3N is stopped by the disk stopper 14 and returns to the initial state where it was stored and held in the original storage chamber _12N .

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

Application Example In the above embodiment, the playback mechanism section 5 is arranged directly below the storage rack 4, but the structure is not limited to this. The storage rack 4 may be placed in any position as long as it is moved and supplied, and for example, it may be placed diagonally below the storage rack 4.

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, the recording disc automatic selection and playback device according to the present invention has the following features.

Since the playback mechanism section is located below where the recording disks in the plurality of recording disk storage sections are fed by their own weight, when transporting a desired recording disk between the recording disk storage section and the playback mechanism section, This can be done by simply supporting the lower part of the outer periphery of the recording disk with a disk carrying member (disk carrying arm), and the disk carrying member can also be moved by simply supporting the outer periphery of the recording disk. Therefore, the configuration of the device can be simplified.

In relation to the above, since the disk transport member does not enter into or cross the recording disk storage section, there is no space between adjacent recording disks stored in the recording disk storage section. There is no need to provide a gap wide enough for the disk transport member to pass through, and it becomes possible to store multiple recording disks in a row with narrow pitches in the multiple recording disk storage sections. It becomes possible to shorten the length of the recording disc storage section, and the device can be made smaller.

The movement of the recording disk from the recording disk storage section to the playback mechanism section below is not a free fall, but movement while being supported by the disk transport member, so there is no possibility that the recording disk may bounce inside the playback mechanism section. This prevents the recording disc from being damaged.
