Description

[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD The present invention relates to an automatic recording disk selection and playback device that moves and plays recording disks in a storage section in a vertical plane. BACKGROUND OF THE INVENTION One of these types of devices is a record disc automatic selection and playback device, a so-called jukebox. In conventional equipment, a large number of record discs (hereinafter referred to as discs) are stored vertically in a rack, facing each other and sequentially aligned horizontally, and a disc player moves along the side of the rack. The arm that grips the designated disc rotates approximately 180° upward in a vertical plane to take out the disc and attach it to the vertical turntable of the disc player. After playing, the arm grips the disc again and rotates in the opposite direction to return it to the rack. 1. Problems to be Solved by the Invention In the above device, the configuration and operation of the disk gripping mechanism of the arm are complicated, and there is a drawback that failures are likely to occur, and this gripping mechanism has a large Since this arm enters a large distance between the disks, the pitch between the disks increases, the overall length of the rack increases, and the device becomes larger. Means for Solving the Problems The present invention provides a disc player that is movably disposed below a rack, and when the disc player stops at a position corresponding to a designated disc, the disc is moved by its own weight. During this time, the disc support part of the arm simply places the disc, supports its own weight, rotates downward in a vertical plane, attaches it to the disc player, and after playback is finished, rotates upward. In addition, disk stoppers are disposed movably in each of the plurality of storage sections of the rack (each storing the disk), and the disk stoppers prevent the disk from falling from the rack due to its own weight under normal circumstances. The object of the present invention is to provide an automatic recording disk selection and playback device that solves the above-mentioned problems by locking the disk in this way and releasing the lock during playback to allow the disk to fall. The configuration for this purpose includes a plurality of recording disk storage sections each storing a plurality of recording disks in a vertical position, and a recording disk qI) that moves along the storage section and stops at a position facing the specified storage section. , a reproducing mechanism section for reproducing the inner recording disk that has been moved downward from the storage section, and a reproducing mechanism section that is displaceably disposed within the extension plane of the corresponding storage section and that is in contact with the outer periphery of the recording disk inside the storage section, respectively. A plurality of disk stopper members that are locked to prevent downward movement, and a disk stopper member that corresponds to the recording disk in the designated storage section are displaced to release the lock to the recording disk to allow immobility. It consists of a lock release means. Embodiment FIG. 1 does not show a compact disc automatic selection and playback apparatus 1, which is an embodiment of the recording disk automatic selection and playback apparatus according to the present invention. The device 1 is installed horizontally on the upper part of the frame 2, and connects the disks 3 (
Disk storage rack 4 for storing disks (hereinafter referred to as disks)
and a reproducing mechanism section 5 which has a built-in disc reproducing device and is supported at a position directly below the disc storage rack 4 so as to be movable along the storage rack 4. As shown at 01 in FIG. 2, the disk storage rack 4 has a generally rectangular frame shape, and both side walls along the longitudinal direction are formed into a comb-like shape with a large number of partition wings 10 connected by side plates 11. It has a unique structure. A pair of opposing partitions 9 and 10 cooperate to form a flat disk storage section 12, and the storage rack 4 has a structure in which a large number of disk storage sections 12, for example 100 disk storage sections 12, are closely aligned in the longitudinal direction. It becomes. The 100 disk storage units 12 are numbered in order. Further, a minus slit 13 is formed corresponding to each disk storage section 12. Furthermore, each disk storage section 1

The disc stopper 14 is supported by a shaft 15 and placed between adjacent partitions 10, and is biased counterclockwise in the t1 direction by a spring 16 and normally rotates in the same direction. protrudes inward. Further, both the large moon part and the bottom part 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 disc 3 is placed at a position A+ on the side of the outer peripheral edge 3a.
, A2 is locked by the side plate 11 to restrict its rolling, and the downwardly located portion △3 is locked by the stopper 14 to restrict its downward movement (fall), and furthermore, the partition blade 10
The discs 3 are housed in the storage rack 4 in a manner that they are reliably separated from the adjacent disks 3 and their inclinations are restricted so that they do not come into contact with the adjacent disks, and are lined up in a vertical position with their surfaces facing each other. In this case, when each disk 3 is released from the stopper 14, it descends under its own weight, and is in a state where it can be removed from the storage section 12 and removed from the storage rack 4 through the bottom opening 18. It is stored in the storage rack 4. In this case, 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 large enough for the arm to pass between every other disk. , the disks 3 are aligned at a small pitch. In this embodiment, the thickness of each partition blade 10 is about 1 mm, the pitch of the partition palanquins 10 is about 3 mm, and -C is used.
are closely packed with a narrow pitch of approximately 3 mm. Therefore, even when storing as many as 100 discs 3, the length L of the storage rack 4 can be as short as about 3Qcm, and the apparatus 1 is configured to be compact. The regeneration mechanism section 5 is supported by a pair of guide rods 20 and 21 which are horizontally mounted on the frame 2 on both sides, and when a pinion 23 rotated by a motor 22 moves on a rack 24, the guide rods 20 and 21 .21 and moves in the arrow X+ and X2 directions. As shown in FIGS. 2 to 6, the playback mechanism section 5 includes a disk playback device 25. Disc player shift mechanism 26 for shifting the disc player. A disk transport mechanism 27 simply supports the disk and transports it between the rack 4 and the playback mechanism section 5, and a disk guide mechanism 28 guides the disk ejected from the playback mechanism section. Alignment mechanism 29 for aligning the disk guide mechanism with a predetermined disk storage portion 12 of the storage rack. Disc clamp mechanism 30 that clamps the disc during playback. Disk leveraging mechanism 3 that separates adjacent disks from each other in the storage section where the disk is returned when returning the disk to the storage rack.

The lever 50 is guided by the lever 50 and moves in the arrow Y+ and Y2 directions. In the initial state, the lever 50 moves in the direction of arrow Y2 as shown in FIG.
6 is rotating counterclockwise. In addition, at the tip of the arm 46, there is a disk catcher 61 that supports the outer peripheral edge 3a of the disk 3 while restricting free displacement in the surface direction of the disk 3. The disk guiding machine 41428 is shown in FIGS. 4 to 6.
As shown, each of the inclined guide portions 51a and 52a consists of a pair of guide plates 51 and 52 arranged to face each other and cover each other. The guide members 51 and 52 are biased toward each other by springs 53 and 54 on both sides, and the inclined guide portion 51a
, 52a are butted together with positioning plates 55 and 56 sandwiched at both ends. In this state, the inclined guide parts 51a and 52a are in an inverted V shape when viewed from the side.
A sub-elongated frontage 57 is formed between the inclined guide portions 51a and 528, and the width is slightly larger than the thickness of the disk 3. be done. Note that the negative guide plate 51 is located in the cam groove 35B of the cam surface 35B.
The expansion lever 58 is locked by the arm portion 58a of the expansion lever 58, which is guided by the + and rotated as shown in FIG. 4, and can be displaced in the direction of arrow x1. When the guide plate 51 is displaced in this way, another guide plate 52 is moved in the direction of the arrow
Displaced in two directions. That is, both guide plates 51 and 52 are displaced in the direction away from each other, and the width of the frontage is narrowed, so that the disc can easily enter the playback mechanism section 5. Further, both guide plates 51 and 52 are attached so that they can be displaced somewhat in a flat curve without changing the frontage width, and are displaced according to the position of the alignment plates 55 and 56, as will be described later. Alignment t! The first structure 29 has an arrow Z+ on both ends of the frontage 57.

It becomes more. In the initial state, the alignment plates 55 and 56 are displaced in the direction of arrow Z2 and recessed into the regeneration mechanism section 5, and when the cam gear A735 rotates, the rotation arms 62 and 63,
They simultaneously move in the direction of arrow Z1 via the connecting arms 64 and 65, protrude from the playback mechanism section 5, and enter the storage rack 4. It should be noted that each alignment plate 55, 56 has a thickness slightly larger than the thickness of the disk 3, and this determines the width usage of the frontage 57 when guiding the disk. The disk clamp mechanism 30 is shown in FIGS. 3 and 5.

It consists of B's Kamunri 35 B-2. 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 is shown in FIGS. 3 and 6.
As shown in the figure, a rotating arm assembly that is kicked and rotated by the disc separator tough 3 on the guide plate 51 and the protrusion g35B=3 of the cam surface 35B and displaces the disc separator tough 3 in the direction of arrow Y+. It consists of a solid body 74. When the disc separator tough 3 moves in the direction of arrow Y1, the beak-shaped portion 73a enters near the lower edges of the adjacent discs 3, forcibly separating the adjacent discs 3 and returning them to the storage rack 4. This creates a path for the disc to pass through. Note that the disc separator tough 3 has a long hole 75a in the presser plate 75. It can be displaced by being guided by a spring 75b, and normally moves in the direction of arrow Y2 by a spring 76. Further, when the rotating arm assembly 74 is kicked by the protrusion 35B-3 while the cam gear 35 is rotating in the arrow B+ direction, the arm assembly itself is bent and does not rotate, and the cam gear 35 is rotated in the arrow B+ direction.

It is in the state shown below. That is, the disc 3 is locked to the disc stopper 14, the disc transport arm 46 is rotating counterclockwise, the alignment plates 55 and 56 are lowered, and the disc player 25 and disc clamper 72
are both located far apart from each other, and the disc guide plate 51.
52 are separated from each other, and the frontage 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, the motor 922 is started and the binion 23 is moved on the rack 24, so that the regeneration mechanism section 5 is guided by the guide rod 20.21 and moves in the direction of the arrow x1 or x2. , and the position where the slit detector 80 detects the slit 13 at the predetermined location, that is, the reproduction m
The disk receiving position P of the hM structure is stopped at a position facing directly below the disk 3N in the disk storage section 12N at the specified 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 B+ via the worm 81. When the cam gear 35 rotates, the lever 50 moves in the direction of arrow Y1 in FIG.

rotate in the counterclockwise direction and in the i1 direction, and the alignment plates 55 and 56 both move in the direction of arrow Z1 and rise (see FIG. 8(B)), inside the storage section 12N in the storage rack 4. ,
That is, it enters into the gap between adjacent partition wings 10 forming the storage section 12N. 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. 9(B). When the cam gear r35 rotates further, the alignment plates 55 and 56
further enters the storage portion 12N, and each alignment plate 55.5
6 is regarded as a member protruding directly below both ends of the storage portion 12N, and is in a hanging state. Therefore, in this state, each alignment plate 55
．． Reference numeral 56 serves to control the position of guide plates 51 and 52 so that they align with the storage portion 12N when the disc is returned, which will be described later. Further, the alignment plate 56 on one side pushes up the disk stopper 14 and rotates it in the 1 direction. Since the disk 3N is floating above the disk stop horn 14, the weight of the disk 3N does not apply to the rotation of the disk stopper 14 in the unlocking direction, and the disk locking of the disk stopper 14 is released. The movements should be light and smooth. As a result, the device 1 is brought into the state shown in FIG.
It is supported by the disc catcher 61 (disk catcher 61). When the cam gear 35 rotates further, the lever 50h<arrow Y
After moving in two directions, the disk transport arm 46 starts rotating counterclockwise. In response to the counterclockwise H1 direction of the arm 46, the disk 3N (while being supported by the disk catcher 61) descends under its own weight and is removed from the storage portion 12N as shown in FIGS. 9(D) and 10(B). Then, it enters into the flat guide space 41 in the regeneration mechanism section 5 from the lower edge side through the frontage 57 in the fully open state. Cam gear 35 rotates further? l-

supplied to After the disk 3N is removed from the storage rack 4, it is guided along both sides of the disk by ribs on both sides (not shown) on the guide panel 39 side and moves directly downward.
When the disc is supplied to the playback mechanism section 5, the lower end of the disc is further supported by the lower rib (not shown) of the guide panel 39.
Since the disc 3N moves under its own weight while being held in the playback mechanism section 5 (guiding space 41) without being transferred, the disc 3N is moved from the storage rack (storage section 12N) to the M student 1 store building. 5
When the disc is transported inside the disc, the disc catch 1761 simply supports the outer peripheral edge 3a of the disc 3N and curves with the bracket (), eliminating the need for a mechanism to grip the disc, and the structure of the disc transport mechanism 27 is simple. becomes. Also disk 3

761) and lowers at an appropriate speed, which is preferable from the standpoint of protecting the disk 3N. At the final stage of rotation of the cam gear 35, the disc player shift mechanism 26 and the disc clamp mechanism 30 operate, and the disc player 25 moves (forward) in the arrow x1 direction and the disc clamper 72 in the arrow x2 direction. disc 3
N is slightly lifted up by the guidance of the clamper 72 until it becomes concentric with the disk player 5, and then clamped around its center hole as shown in FIG. 10(C). Subsequently, the -C1 disk player 25 operates, the A' disk 3N rotates at high speed within the playback mechanism section 5, and the disk 3N is played back. When the reproduction of the disk 3N is completed, the motor 38 is started again and rotates in reverse, so that the cam gear A735 rotates in the direction of arrow B2. When the cam gear A735 rotates in the opposite direction, Fig. 8 (A),
As shown in (B), (D), and (E), the disk transport mechanism 271 and the alignment mechanism 29. Disc player shift mechanism 2
6 and disk clamping machine 8430 simply operate in the opposite direction to that in the disk loading mode described above. Further, the disc guide am2B operates so as to be able to guide the disc as shown in FIG. 8(C), and the disc separating mechanism 31 also operates as shown in FIG. 8(F).
Ru. At the beginning of rotation of the cam gear t135, the disc player 25 and the disc clamper 72 move away from each other, and the disc 3N is unclamped from the disc player 25 (see FIG. 10 (D>). Then, the arm 46 rotates in the R1 direction, and the disc catch A761 locks the outer periphery 3a of the disc 3N and pushes up the disc 3N.
Ejection of the disc N from the disc player 25 is started. At the initial stage of ejecting the disk 3N, the disk guide 11
28 operates as shown in FIG. 8(C), and the guide plate 51.
52 sandwich alignment plates 55 and 56 in close proximity to each other as shown in FIGS. 4, 6, and 10(D). Thereby, the disk guide mechanism 28
a, 52a are in a suspended state guiding the disk 3N ejected from the playback IIAM 4 section 5, and the opening 57 is in a hanging state.
The opening is formed into an elongated opening with a width slightly larger than the thickness of the disk storage section 12N, and is positioned exactly below the disk storage section 12N. In addition, in FIG. 3, the rotating arm assembly 74 is kicked by the protrusion 353-3 and rotates counterclockwise in the 81 direction, and the disc separator tough 3 is slightly displaced in the arrow x2 direction and points at two points in the arrow Y2 direction. Move to the position indicated by the chain line. The disk separator tough 3 is then immediately returned to its original position by the spring 76 (see FIG. 8(F)). As shown in FIG. 10(D), the beak-shaped portion 73a of the disc lever ray tough 3 is located directly above the frontage 57 and is attached to the discs 3 on both sides of the disc 3N.

As shown in FIGS. 9(C) and 9(B), the disc is reproduced (completely ejected from the disk unit 5 and returned to the original storage unit 12N. This disc is returned to the original storage unit 12N. The operation of returning the disk to the disk 3N is also carried out by the disk catcher 61 simply locking the outer peripheral edge 3a of the disk 3N and pushing it up.
The structure of the disk transport mechanism 27 is simpler than that for gripping a disk. Disk 3N is storage section 1
2N, the alignment plates 55, 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. 9(B). When the cam gear 35 rotates further, the arm 46 starts rotating counterclockwise. As shown in FIG. 3, the cam gear 35 rotates to the original position where the protrusion 35B-3 is detected by the microswitch 82 and then stops. In this state, as shown in FIGS. 9(A) and 10(A), the disk 3N is locked by the disk I-flange 14 and stored and held in the original storage portion 12N. Returns to the initial state. As the above operation cannot be repeated, the designated discs in the storage rack 4 are returned to the original storage section of the storage rack after being played, and are sequentially selected and played. Next, the disk stopper 14 and its related mechanisms, which form the essential part of the present invention, will be explained in more detail with reference to FIGS. 11 and 13. In FIGS. 11 and 12, the disk stopper 14 (thickness t
I) is the upper end abutting part 14a, the part 14 to the intermediate disc part 1;
b. It has a lower end abutted part 14C and a spring locking convex part 14d, and is supported so as to be rotatable within the extended plane of the corresponding disk storage part 1'2 (I+] dimension jz) with respect to the shaft 15. . Both ends of the spring 16 wound around the shaft 15 are respectively locked to the horizontal plate part 6 and the spring locking convex part 14d of the storage rack 4, so that the disk stopper 14 is biased counterclockwise in FIG. The abutting portion 14a is stopped at a position where it abuts against the right side plate 11, and the disk locking portion 14b protrudes into the disk storage portion 12. In this state, the disk 3 (thickness I3 is 1.2 mm+Pi! degrees) is stored in the storage portion 12, and the downwardly disposed portion A3 abuts against the disk locking portion 1411, thereby locking its downward movement. Further, the alignment plate 56 (thickness: 4) on the right side in FIG. 11 enters into the storage portion 12 and pushes up the stopper 14 as described below. Therefore, the stopper 14 (thickness I3), the storage section 12 (
Width t2), disk 3 (thickness I3) and I9 mating plate (thickness ta) have the following relationship: (I2 ta)<j 1<t 2
, and the relationship (C2j+)<I4<tz must hold. Therefore, the displacement space of the C disk stopper 14 is within the extended plane of the corresponding disk storage portion 12, and does not have any effect on increasing the thickness of the disk 3 in the axial direction. By reducing the pitch between the racks, the length of the rack 4 can be reduced, and the entire rack can be made smaller. In addition, in FIG. 11, the weight of the disk 3 is received by the disk locking portion 14b of the core lock 14, and the load acts in the direction shown by arrow F from the core locking portion 14b in the same figure, and is transferred to I5. The rotation center of the stopper 14 is I41. That is, the shaft 15 is located upward from the line of action. Therefore, the stopper 14 has an anti-tri i
A rotational moment in the force direction is applied, and by competing with the force of the Gf spring 16, the stopper 14 is reliably held at a position where the contact ii 14a contacts the side plate 11, thereby locking and suspending the disk 3 at an accurate position. Note that when the rotational moment due to the weight of the disk 3 acts in the opposite rotational direction to that described above, the stopper 14 rotates in the direction i:() against the force of the spring 16, and the disk 3
However, if the rotational moment due to the weight of the disk 3 is applied to prevent the stopper 14 from rotating counterclockwise in FIG. 11, the spring force of the spring 16 is relatively small. Good. Here, as shown in FIG.
735 Which interlocking is used to connect disc 3?
When the limit of rotation in the IT direction is reached, the upper end concave part (not shown) of the disc catch A761 abuts and locks the lower end Δ4 of the disc 3, and the 1st disc locking position is shown by the two-dot chain line in the figure. This is shown in Figure 8 (
8) Middle time a〉, after that the arm is u4 in the same figure (△)
It stops at 10 motion limits from time a to time. However, during this period, the alignment plate 56 also starts to move upward in conjunction with the cam gear 35, but it contacts the lower end abutted portion 14c of the disc stopper 14 at time a in FIG. Keep pushing this up. Therefore, from the time when the lifting of the dimensions of the disk 3 is completed, the stopper 14 is pushed up against the spring 16 by the positioning plate 56, and by the time the stopper 14 rotates clockwise to the position shown in FIG. The stop portion 14b falls outward from the inside of the right side plate 11. In this way, the disk 3 is unlocked and allowed to move downward. Subsequently, as the arm 46 rotates in the counterclockwise direction as described above, the disc 3 starts to move downward and is moved to the playback position while its downward movement is regulated by the disc catcher 61 due to its own weight. During this time, the stopper 14 continues to maintain the state shown in FIG. 13 because the alignment plate 56 continues to be at the upper limit of movement as shown in FIG. 8(B). At the end of playback, the arm 46 rotates clockwise again to bring the disc 3 past the two-dot chain line position in FIG. Δ) The rotation limit in the 11 direction is reached at the middle time, and contrary to the above, the rotation is stopped at this position until time a'. At this time, the plate 56 starts to move downward in the opposite direction to the above, and the stopper 14 starts rotating counterclockwise/j direction, and returns to the position at the time a' as shown in FIG. At contact part 1
4a returns to contact with the side plate 11 and returns to the state shown in Fig. 11.
'The isk can be locked. From now on, the alignment plate 56
is gradually decreasing, but at the above time a'('//-m4
6 starts rotating in the counterclockwise Iit fr direction again as shown in FIG. 8(A). Therefore, the disk 3 also follows this and starts moving downward in C, and moves downward in dimension V until the point A3 on the downward side reaches the stopper 1.
The contact portion 9'JL'(
It is locked. According to -C1 According to the above configuration and operation, as described above,
The disk 3 moves by its own weight when moving downward, and the disk catcher 61 of the arm/16 only needs to simply place the disk 3 and support the disk 3, and also supports the weight when moving upward. Therefore, the structure 1 mechanism of the arm 46 is simplified, and since the arm 46 does not enter between the disks 3, the pitch between the disks 3 can be further reduced, and the overall size can be further reduced. In addition, since the reciprocating rotation of the disk stopper 14 is always performed with the disk 3 raised by two dimensions, the stopper 14 does not rub against the disk 3 during rotation.Therefore, the stopper 14 and the disk 3 are locally Prevents wear and tear
Further, when the stopper 14 is rotated, there is no negative effect due to the weight of the disc 3, so the rotational load is small, allowing the rotation to be performed easily and improving operational accuracy. Therefore, from this point of view as well, the spring force of the spring 16 is relatively small. Therefore, a total of 100 springs 16, each corresponding to the 100 disks 3, do not exert a very large spring force on the storage rack 4, so there is no risk that the rack 4 will bend due to these spring forces, and the rack By reducing the thickness of each plate in 4, the weight can be reduced. As described above, the recording disc automatic selection and playback device according to the present invention has the following features. ■ A plurality of disk stoppers, which are provided in correspondence with the plurality of storage sections of the rack and which lock or release the disks, are displaceable within the extended plane of each storage section, so that the disk The displacement space of the stopper can reduce the pitch between storage sections, reduce the length of the -C rack, and downsize the apparatus without affecting the dimensions of the disks in the stacking direction. 1) The disk stopper is made rotatable and is rotated by the spring means in the direction of locking the disk, and the insects due to the disk's own weight move against the disk stopper in the same rotation direction as above. The rotational moment is applied to stabilize the locking mechanism, so that the disk stopper is reliably held in the disk locking position by the action of the cart due to the weight of the disk in addition to the spring means. The disc can be locked stably and reliably, and the disc is the center of rotation. The structure is simple as only the spring means is provided, and the assembly work is easy. (2) Therefore, the spring force of the spring means shown in Us and L is relatively small, which can reduce the spring cost, and the force exerted by the spring means on the structure of the rack is also small, allowing the rack to be made thinner and lighter.
