Disk transport means 40 (hereinafter, referred to as a disk transport unit 40) for transporting the disk 4 after returning the tray 3 to the original storage position of the rack, and disposed below the left and right racks 10 and 11. Then, the disk 4 conveyed by the disk conveying unit 40 is placed on the tray 5 for the disk playing unit and played by the disk playing means 120 and 121 (hereinafter, referred to as disk playing means).
The disk transport units 120 and 121) and a disk transport unit drive mechanism 20 that is disposed at the upper left of the housing 2 and moves the disk transport unit 40 up and down.

<< Rack Structure and Tray for Rack >>
FIG. 2 is a perspective view showing the structure of a rack used in the multi-load automatic disk playing apparatus according to the present invention, FIG. 3 is a plan view for explaining the tray lock mechanism shown in FIG. 2, and FIG. ) Is a perspective view showing a rack tray, and FIG.
FIG. 3 is an XY cross-sectional view of FIG.

The racks 10 and 11 shown in FIG. 1 are formed in a substantially symmetrical shape. Here, the left rack 10 will be described with reference to FIG.

In FIG. 2, a rack 10 is formed in a box shape, and a shaft 12 is fixed to a corner of a top plate 10a and a corner of a bottom plate (not shown). As shown by the two-dot chain line in FIG. 1, the disk 4 can be rotated to the front direction, the disk 4 can be easily placed on the tray 3 easily, and the entire rack 10 can be detached from the apparatus 1. Supported.

Returning to FIG. 2, the left and right side plates 10 of the rack 10
b, 10c, a plurality of grooves 10d facing each other.
(Only the right side plate is shown) is formed. This groove 10
The pitch P of d is as narrow as 3 mm or less.
The tray 3 on which the discs 4 are placed is stored in a stacked state in d. Here, for example, about 200 discs 4 are placed on the tray 3. Then, for example, disc 4
Each block is divided into four blocks and stored as one block. At this time, between the 50 th and 51 th of divided discs 4 are large gap S ₁ is formed on the left and right sides.

A groove 10 is provided in front of the left side plate 10b.
A plurality of tray lock mechanisms (tray locking means) 13 for locking the tray 3 stored in the tray 3 are provided. The tray lock mechanism 13 is formed to have a length L that can lock, for example, ten trays 3 at a time. This is because, as described above, since the interval between the adjacent trays 3 is narrow, the locking mechanism for locking the trays 3 one by one becomes complicated and there is no space. The tray lock mechanism 13 is provided with a shaft 14 vertically suspended as shown in FIG.
Of the tray 3 is always urged in the counterclockwise direction by the compression spring 16 so that the notch 3a formed at the tip of the tray 3 is moved to the arm of the lock lever 15. Locked at 15a. To release the lock, a tray lock release mechanism 50, which will be described later, of the disk transport unit 40 is moved in the direction of arrow A, and the arm 15b is connected to the arm 15a via the shaft 14.
, And the lock can be released by rotating the lock lever 15 clockwise against the compression spring 16. It goes without saying that the tray lock mechanism 13 can be unlocked manually. The tray lock mechanism 13 provided on the rack 11 is opposed to the rack 10. At this time, the tray other than the tray 3 on which the desired disk 4 is placed is placed in the disk transport unit 40.
Tray stopper portion 41d which locks so as not to be pulled out
41d (FIG. 6) is formed as described below. By providing the tray lock mechanism 13, a plurality of trays 3 can be simultaneously locked to the racks 10 and 11 at the same time, so that the lock mechanism is simplified and the number of parts can be reduced.
And the space is no problem.

In front of the right side plate 10c, a square position detection hole 10e for detecting a tray position for each tray 3 is provided.
There are bored between the position detection hole 10e adjacent are formed small gaps S _2. Then, a large gap S ₁ and a small gap S ₂ described above may function in positioning in selecting a tray 3 mounted with the desired disk 4 by the photo sensor 42, 42 to be described later of the disc conveying unit 40 (FIG. 6) I do.

Next, the rack tray 3 will be described with reference to FIGS. 4 (A) and 4 (B).

The tray 3 is integrally formed with a very thin plate thickness T (about 1.5 mm) using a resin material or the like, and is provided substantially in the center with a circular center hole 3b so as to be continuous with a rectangular shape. Guide holes 3c are formed on the upper surface side along the outer periphery of the central hole 3b to regulate the mounting position of the disk 4.
d and 3d are formed to protrude upward. Then, the center hole 4a of the disk 4 is fitted into the guide rib 3d, and the disk 4 is reliably positioned and mounted on the tray 3. At this time, since the position of the disk 4 is not restricted based on the outer diameter, it is possible to mount a plurality of types of disks 4 having different outer diameters. That is, as shown in FIG. 4 (B), all the diameters of the central holes 4a of the disk 4 are formed to be the same diameter and are fitted into the guide ribs 3d, 3d. (Compact disc) is mounted, and as the small outer diameter disc 4B, for example, a well-known CD having a diameter of 8 cm is mounted, but CDs, VDs (video discs), etc. of appropriate diameters are not limited to this. Can be placed. In addition, the disk 4
Holes 3e, 3e and 3f, 3 for detecting the outer diameter of
f is drilled, and the detection hole 3e is for a small outer diameter.
f is for a large outer diameter. Then, the tray 3 on which the disk 4 is placed is moved to the disk transport unit 4
When it is pulled out to 0, it is detected by a photo sensor (not shown) in the disk transport unit 40 facing these detection holes 3e and 3f. The rack tray 3 having the above-mentioned shape is capable of mounting a plurality of types of disks 4 having different outer diameters, and the means for regulating the mounting position of the disks 4 does not use the outer diameter standard. Since the position is regulated by the hole 4a, the tray 3 can be formed to have an extremely thin plate thickness T, whereby a large amount of the tray 3 on which the discs 4 are placed can be stored in the racks 10 and 11, and the use range of the apparatus 1 Can also be expanded. The shapes of the central hole 3b and the square holes 3c, 3c of the tray 3 are determined by the disk suction mechanism 9 described later.
0 (FIG. 10) can penetrate. Although not described in detail here, in a tray on which disks 4 having different outer diameters are not placed, a concave outer diameter regulating portion is provided without providing the guide ribs 3d, and the central hole 3b is formed so that the disk catcher 109 can pass therethrough. Even if it is formed in a large diameter, no trouble occurs. Also, tray 3
At the front end, clamps 3g, 3g for pulling out the tray 3 from the racks 10, 11 are formed in a "U" shape. The clamp portions 3g, 3g are formed symmetrically on both the left and right sides so that they can be shared by the racks 10, 11 having a symmetric shape. Then, the tray 3 is moved to the disk transport unit 4 by the tray pull-out mechanism 60 (FIG.
The racks 10 and 11 can be returned to their original storage positions.

On the rear surface (lower surface) of the tray 3, a protruding portion 3k (about 0.3 mm) having an extremely low height is formed so as to partially protrude downward in a rib shape. Since the projecting portion 3k is not formed on the entire back surface, the function of the projecting portion 3k prevents the adjacent trays 3 having a small interval from sticking due to dew in the air or static electricity. As a result, only the tray 3 on which the desired disk 4 is placed
Without sticking to the disk transport unit 40, and the reliability of the apparatus 1 is remarkably improved.

Furthermore, the tray length X ₁ between the tip and the rear end portion of the tray 3, tray 3 disc conveying unit 4
When the tray 3 is pulled out, the rear end is formed to have a length that does not completely come out of the groove 10d of the rack 10 (11), and the tray 3 can be easily returned to the original storage position of the racks 10 and 11. ing.

<<<< disk transport unit drive mechanism >>
FIG. 5 is a perspective view showing the disk transport unit drive mechanism.

Before describing the disk transport unit 40 shown in FIG. 1, the disk transport unit drive mechanism 20, which is a drive source for driving the disk transport unit 40, will be described first.

The disk transport unit drive mechanism 20 shown in FIG. 5 is disposed at the upper left of the housing 2 (FIG. 1), and moves the disk transport unit 40 up and down (arrows B ₁ and B _2).
), And a motor braking mechanism 30 that reliably stops the disk transport unit 40 at a predetermined position.

That is, the rotation of the motor 21 is
1a from the worm 22 to the worm wheel 23
, And further transmitted to a timing pulley 24 coaxially connected to the worm wheel 23. Also,
A timing belt 26 is provided between the timing pulley 25 provided at a lower portion of the housing 2 and the timing pulley 24.
The timing belt 26 is connected to a connecting portion 41 a of the transport base 41. In addition, a long shaft 27 that is vertically suspended is fitted into the sliding portion 41 b of the transport base 41. A shaft 2 is provided at the right end of the transport base 41.
Although another guide member for guiding the transport base 41 is provided along 7, the illustration is omitted.

When the motor 21 is driven by the disk transport unit drive mechanism 20 having the above-described structure, the transport base 41 can be moved up and down along the shaft 27. On this occasion,
At the rear end of the motor 21, a disc 28 having a plurality of holes 28a is provided.
Is fixed, and the motor 21 is pulse-controlled by the photo sensor 29. The pulse control of the motor 21 will be described in the section of the disk transport unit 40.

Further, the worm 2 on the opposite side of the motor 21
A brake plate 31, which is a part of a component of the motor braking mechanism 30, is connected to the second shaft 22a. The outer peripheral portion 31a of the brake plate 31 is formed in an uneven knurl or spur gear shape. Also, the brake plate 31
The brake levers 32, 33 each having a "U" shape, one end of which is in contact with the outer peripheral portion 31a, are disposed so as to be rotatable about shafts 34, 35 in opposition to each other. Further, between the brake lever 32 and the brake lever 33, a triangular block 36 and a connecting rod 37 connected to the block 36 are connected to the tip of a solenoid 38. The other ends of the brake levers 32, 33 via the shafts 34, 35 are opposed to each other and can abut on the block 36 or the connecting rod 37. At this time, the block 36 is rotatably connected to the connecting rod 37. A tension spring 39 is mounted between the other end of the brake lever 32 and the other end of the brake lever 33. The tension spring 39 connects one end of the brake levers 32 and 33 to the brake plate 31. From the outer peripheral portion 31a of the solenoid 38, and the leading end of the solenoid 38 is pulled out in the direction opposite to the arrow C direction. In addition, solenoid 3
When the motor 8 is not sucking, that is, when the motor 21 is rotating, the tip of the solenoid 38 is pulled out in the direction opposite to the arrow C direction, and the brake lever 32,
The other end of 33 is in contact with the connecting rod 37, and one end of the brake levers 32, 33 is released from the outer peripheral portion 31a of the brake plate 31. Here, when the energization of the motor 21 is stopped and the solenoid 38 is sucked in the direction of arrow C, the other ends of the brake levers 32 and 33 have a triangular block 36.
And the brake lever 32 pivots counterclockwise about the shaft 34 against the tension spring 39, while the brake lever 33 rotates clockwise about the shaft 35 against the tension spring 39. One end of each of the brake levers 32 and 33 is rotated by the outer peripheral portion 31 a of the brake plate 31.
Can be contacted without hitting the
In addition, the rotation of the brake plate 31 can be reliably stopped. That is, since the block 36 is rotatable, the brake lever 3
The one end of each of the brake plates 2 and 33 can uniformly contact the outer peripheral portion 31a of the brake plate 31 without colliding with one end. Further, since the outer peripheral portion 31a of the brake plate 31 is formed in an uneven shape,
The contact relationship between one end of each of the brake levers 32 and 33 and the outer peripheral portion 31a of the brake plate 31 has a large friction coefficient, and the motor 21 and the brake plate 31 can be reliably stopped. As a result, the disk transport unit 40 can be reliably stopped at a predetermined position. In particular, the braking action between the worm 22 and the worm wheel 23 and the motor braking mechanism 3 are performed so that the disk transfer unit 40 loaded with a heavy object does not fall naturally.
Since the disc transport unit 40 is used together with the braking action of 0, the disc transport unit 40 can be reliably stopped at a predetermined position without naturally dropping downward, thereby contributing to the reliability of the apparatus 1. Note that a friction member such as rubber may be attached to one end of each of the brake levers 32 and 33 without forming the outer peripheral portion 31a of the brake plate 31 in an uneven shape.

Is also rotated clockwise about the shaft 84, so that the lever 80
The shaft 86 fixed to the shaft 86 and the pusher 73 connected to the shaft 86 also move in the arrow H direction. Thus, when the clamper assembly 71 moves to the right end of the upper surface 41c of the transport base 41, the pusher 72 moves the clampers 66 and 67.
The shaft 69, 70 fixed to the press while against the compression spring 68, to move the clamper 66 and 67 in the arrow _{E 1} direction. On the other hand, the clamper assembly 71 is
When the pusher 7 is moved to the left end of the upper surface 41c of the pusher 7,
Shafts 69, 70 secured to clampers 66, 67
While pressing against the compression spring 68, the and moves the clamper 66 and 67 in the arrow _{E 1} direction as well. still,
When the suction of the solenoid 74 is stopped, the tension spring 8
The pushers 72, 73 simultaneously return to their original positions by the urging forces 2, 85.

The shafts 69, 70 fixed to the clampers 66, 67 move along a concave guide groove 87 formed on the upper surface 41c of the transport base 41. This guide groove 87 has wide grooves 87 on the left and right sides.
a, 87b, and two guide grooves 87c, 87d connecting between the grooves 87a and 87b.
As shown in FIG. 6, the wide grooves 87a and 87b are formed to protrude partially from the left and right side surfaces of the transport base 41 in a trapezoidal shape.

[0044] Returning to FIG. 8, the grooves 87a of the wide width, to move the shaft 69, 70 and pushers 72, 73 which is fixed within the arrows _E 1, _{E 2} direction clamper 66 and 67 within 87b, further the front guide The groove 87c guides the shafts 69 and 70 fixed to the clampers 66 and 67 when the clamper assembly 71 not clamping the tray 3 moves, and the clamper assembly 71 clamping the tray 3 in the rear guide groove 87d. Clamps 66 and 67 when moving
Are guided to the shafts 70 and 71 fixed to the shaft.

With reference to FIGS. 9A to 9D, the operation of the tray withdrawing mechanism 60 configured as described above will be described with reference to the drawing of the tray 3 on the rack 10 side to the transport base 41 side. 9A to 9D are schematic plan views illustrating the operation of the tray pull-out mechanism.

First, as shown in FIG. 9A, the clamper assembly 71 is located at an appropriate position in the guide groove 87c on the near side of the guide groove 87. That is, in this state, the clampers 66, 67 are urged forward by the compression spring 68, and the shafts 69, 70 fixed to the clampers 66, 67 are guided by the guide grooves 87c.

Next, the clamper assembly 71 is moved to the left from the state of FIG. 9 (A) to position the clamper assembly 71 in the wide groove 87b, and the clamper support plate 63.
When the side surface of A is brought into contact with the distal end surface of the clamp portion 3g of the tray 3, the state becomes as shown in FIG. 9B. By this contact, the positional relationship between the tray 3 stored in the rack 10 and the clamper assembly 71 on the side of the transport base 41 is reliably determined. Again, the clampers 66, 67 are compression springs 68.
Urged forward.

Next, as shown in FIG. 9 (C), a shaft 69, 70 fixed to the clamper 66 and 67 by the pusher 73 in the groove 87b of the wide width in the arrow _{E 1} direction against the compression spring 68 Push. Thereby, the tip of the clamp portion 67a of the clamper 67 enters the “U-shaped” clamp portion 3g of the tray 3. When the clamper assembly 71 is immediately moved rightward while pushing the pusher 73, the clamp 67a of the clamper 67 is moved to the clamp 3g of the tray 3.
Is pulled out to the right, and the shafts 69, 70 fixed to the clampers 66, 67 enter the rear guide groove 87d. If the shafts 69, 70 enter the guide grooves 87d, the clampers 66, 67 cannot move in the forward direction, and the clampers 67 keep the tray 3 clamped. The clamper 66 is located on the tray 3 on the rack 11 side.
It works when clamping.

Then, as shown in FIG. 9D, the clamper assembly 71 is further moved rightward to
Is stopped before it completely enters the wide groove 87a. That is, the left and right stoppers 44 and 45 provided at the entrance of the guide groove 41h in FIG. 6 rotate according to the movement of the tray 3, and here the tray 3 pushes down the stopper 44 and passes therethrough and is stopped by the stopper 45. It has become. The tip of the clamp 3g of the tray 3 is
5, the shaft 70 fixed to the left clamper 67 is still positioned in the guide groove 87 d and clamps the tray 3. From this state, the process proceeds to a disk suction operation described later. In the state of FIG. 9D, the clamper 66 and the clamper 67 can move independently of each other as described above, so that the shaft 69 fixed to the right clamper 66 completely enters the wide groove 87a. So that it has returned to the lower position as shown. And
To return the tray 3 to the original storage position of the rack 10 after the end of the disk suction operation, the tray 3 may be moved to the left, contrary to the above. At this time, the shaft 70 is guided by the upper guide groove 87d, while the shaft 69 is guided by the lower guide groove 87c.
Returned to be guided. Here, the rear end 3i of the tray 3 does not completely come out of the groove 10d of the rack 10 as shown in FIG. Thereby, the operation of returning the tray 3 to the original storage position of the rack 10 becomes easy.

The tray pull-out mechanism 60 having the above configuration
Are either the left or right tray 3 or 5 by the same drive source.
Can be selectively pulled out or returned, and the drive control of the tray drawer mechanism 60 is facilitated. Further, the mechanism of the tray pull-out mechanism 60 is simplified, so that it can be disposed with a good space efficiency, and the disk transport unit 40 can be downsized.

Next, the disk suction mechanism 90 for sucking the disk 4 mounted on the rack tray 3 or the disk 4 mounted on the disk playing unit tray 5 will be described with reference to FIG. FIG. 10 is a sectional view for explaining the disk suction mechanism shown in FIG.

In the disk suction mechanism 90 shown in FIG. 10, an arm 91 movable vertically (in the directions of arrows J ₁ and J ₂ ) is provided above the upper surface 41 c of the transport base 41. It is supported by. The shaft 92 penetrating through the hole 91a of the arm 91 is suspended from the flat surface 41j and is supported by an L-shaped bracket 93 fixed to the rear surface 41k. A driving source for moving the arm 91 in the vertical direction is a motor 94 disposed inside the transport base 41. That is, the worm 95 fixed to the shaft of the motor 94 meshes with the worm wheel 96, and one end of a connecting rod 97 is connected to the worm wheel 96. Further, the other end of the connecting rod 97 is connected to the arm 91, and this connection is made via a compression spring 98. This is because the motor 94 moves the tray table 100 described later minutely up and down simultaneously, so that the compression spring 98 buffers the arm 91 so that the arm 91 does not operate over a certain range.

[0053] Moreover, almost the tray table 100 is a stepped through hole 41m formed in the central portion is movable in only slightly up and down (arrows _K 1, _{K 2} direction) of the upper surface 41c of the conveying base 41 ing. A lid 101 having a central hole 101a is fixed to a lower portion of the stepped through hole 41m, and closes the stepped through hole 41m.

The stepped cylindrical tray table 100 urged downward by the compression spring 102 is fitted into the closed stepped through hole 41m. Further, a hanging part 100a which is hung downward is formed in the lower center part of the tray table 100. The hanging part 100a penetrates through the center hole 101a of the lid 101, and further has a hanging part 100a.
A pin 103 fixed to the lower end of a is in sliding contact with the cam wheel 104. A substantially spiral cam is formed on the cam wheel 104, and the small-diameter cam surface 104a and the large-diameter cam surface 104b are spirally connected. When the pin 103 is in sliding contact with the small-diameter cam surface 104a, the tray is closed. The upper surface 100b of the table 100 is the upper surface 41c of the transport base 41.
And when the pin 103 is in sliding contact with the large-diameter cam surface 104b,
b can protrude slightly above the upper surface 41c of the transport base 41.

The drive source of the cam wheel 104 shares the motor 94 for driving the arm 91 described above.
The rotation of the timing pulley 96 a formed integrally with the worm wheel 96 is transmitted to the timing pulley 106 via the timing belt 105, and further, the gear 106 a formed integrally with the timing pulley 106 transmits the relay gear 1.
The rotation of the cam wheel 104 is transmitted to the gear portion 104c of the cam wheel 104 via the reference numeral 07.

The upper surface 100 of the tray table 100
A hole 100c, which is stepped and does not penetrate, is formed in the center of b, and a permanent magnet 108 that generates a weak magnetic force is fixed below the hole 100c. Further, a disc catcher 109 made of soft magnetic iron or the like is detachably fitted above the permanent magnet 108 in the hole 100c. The distal end of the disk catcher 109 is formed in a shape that can be fitted into the central hole 4a of the disk 4 and can also be fitted into a guide hole 91 described later. Part 10
9a are formed.

Further, a cylindrical protruding portion 91b is formed to protrude downward from the distal end of the arm 91, and the cylindrical protruding portion 91b is formed on the upper surface 100b of the tray table 100.
Facing. A concave hole 91c is formed in the projecting portion 91b of the arm 91 from above, and the concave hole 91c is formed.
At the lower center of c, a ring-shaped guide hole 91d concentric with the hole 91c is provided, and the ring-shaped guide hole 91d is formed to protrude above the center of the hole 91c.

An electromagnet 110 is fixedly fitted into the outer diameter of the ring-shaped guide hole 91d. This electromagnet 1
Reference numeral 10 denotes a known structure in which a coil is wound inside, in which the direction of the generated magnetic force changes according to the direction of the current.

The electromagnet 1 is inserted into the hole 91c of the arm 91.
Above 10, a soft magnetic core 112 having a permanent magnet 111 fixed to the outer periphery is provided movably up and down (in the directions of arrows L ₁ and L ₂ ). The soft magnet core 1 is formed by the permanent magnet 111.
A magnetic force is always acting upward on 12. Also, holes 91
The upper part of c is closed by a lid 113, and the soft magnetic core 112 to which the permanent magnet 111 is fixed is urged upward by a compression spring 114.

At the center of the soft magnetic iron core 112, a downwardly projecting attracting portion 112a is formed, and at the outer peripheral portion, a downwardly projecting magnetic path forming portion 112b is formed. The guide hole 91d is fitted into the guide hole 91d from above. Further, the leading end of the disc catcher 109 fits into the guide hole 91d from below at the time of a suction operation to be described later.
This is a structure that is adsorbed by a.

The operation of the disk suction mechanism 90 configured as described above will be described with reference to FIGS. 10, 11 (A) to 11 (C) and 12 (A) to 12 (D). 4 will be described. In addition, FIG.
12C is a diagram for explaining the operation of the disk suction mechanism, and FIGS. 12A to 12D are schematic diagrams for explaining the suction force relationship of the disk suction mechanism.

First, as shown by the two-dot chain line in FIG. 10, the disc 4 placed on the tray 3 is placed on the upper surface 41c of the transport base 41 by the above-described tray pull-out mechanism 60 (FIG. 6). Shall be drawn from

The arm 91 is lowered from the state shown in FIG. 10, and the protrusion 91b of the arm 91 is brought into contact with the upper surface of the disk 4 as shown in FIG. Also,
The pin 103 fixed to the hanging portion 100a of the tray table 100 with the lowering operation of the arm 91 moves the cam wheel 1
04, and slides on the large-diameter cam surface 104b of the tray table 1.
The upper surface 100b of the sheet No. 00 projects upward and comes into contact with the back surface of the tray 3. The guide hole 91d of the arm 91 and the center hole 4a of the disk 4 are opposed to each other.
d also faces the lower disk catcher 109 as described above. Here, the soft magnetic core 112, as shown in FIG. 12 (A) and acts constantly force of _{P 1} is above the permanent magnet 111, whereas, according to the permanent magnet 108 is disposed below the disc catcher 109 -P The magnetic force of No. ₃ is acting downward. Therefore, the soft magnetic core 112 and the disc catcher 109 repel each other, and the soft magnetic core 11
2 and because the disc catcher 109 apart intervals, it is impossible to move the force P ₁ in the disk catcher 109 of the soft magnetic core 112 upwardly, the remains disc catcher 109 is adsorbed to the permanent magnet 108 Have maintained.

Next, from the state shown in FIG.
Operating 0 causes the state shown in FIG. 11B. That is, during the adsorption operation as shown in FIG. 12 (B), the magnetic force of P ₂ to the electromagnet 110 to control the current direction to work upwardly, shown through the magnetic path forming portion 112b as the direction of the arrow of a magnetic path is formed P ₂ of the magnetic force is generated, the magnetic force of the soft magnetic core 112 is magnetic force of P ₂ on the magnetic force of P ₁ is added. Here, as shown in FIG.
2 is attracted to the electromagnet 110 side and the compression spring 114
Moves downward (arrow L ₂ direction) against the. As a result, the distance between the soft magnetic core 112 and the disc catcher 109 is reduced, and the added magnetic force P ₁ is applied to the soft magnetic core 112.
The adsorption force between the magnetic force P ₂ acts strongly upwards, overcoming the force -P ₃ disc catcher 109. As a result, the disc catcher 109 located on the back of the tray 3
Is inserted through the center hole 3b and the square hole 3c of the tray 3, and further fitted into the center hole 4a of the disk 4 and fitted into the guide hole 91d of the arm 91, and is attracted to the attracting portion 112a of the soft magnetic core 112. Is done. Disc catcher 109
Is attracted to the soft magnetic core 112, the flange 109a of the disc catcher 109 comes into contact with the back surface of the disc 4, and the disc 4 is attracted and floated upward. And
The disk 4 is securely held between the lower surface of the projecting portion 91b of the arm 91 and the sucked flange 109a of the disk catcher 109, so that the disk 4 moves from the tray 3 toward the arm 91 and is held.

Next, when the disk 4 is held on the arm 91 side, the arm 91 is moved upward (arrow J) as shown in FIG.
₁ direction). As the arm 91 moves upward, the pin 103 fixed to the hanging portion 100a of the tray table 100 is moved to the small diameter cam surface 104a of the cam wheel 104.
, Which causes the tray table 100 to move downward. At this time, when the power is turned off as shown in FIG. 12C, the power supply to the electromagnet 110 is stopped. Thus, the disc catcher 109 holds the left disc 4 is attracted to the soft iron core 112 by the magnetic force of P ₁ of the permanent magnet 111. The reason why the energization of the electromagnet 110 is stopped is that the disk 4 can be securely held even during a power failure and the power of the apparatus 1 can be saved. At this time, it goes without saying that the electromagnet 110 may be kept energized when the arm 91 is moved. In the embodiment, the electromagnet 110 and the permanent magnet 11
1 and a self-holding structure, but the electromagnet 110 is simply turned on without using the permanent magnet 111.
In this case, the electromagnet 110 must always be turned off to hold the disc 4 on the arm 91 side.
N operation must be performed. By the above operation, the disk 4 is securely held on the arm 91 side, and it is not necessary to place the disk on the tray 3, so that the transport of the disk 4 is ensured.

Further, the principle of returning the disk 4 held on the arm 91 side to the tray 3 is that the current direction is controlled in the non-suction operation as shown in FIG. I do. Thus the direction of the arrow of the magnetic path of the as shown in the drawing formed magnetic force of the -P ₂ occurs, the soft magnetic core 112
Is a magnetic force of P ₁ -P ₂ . At this time, P ₁ -P ₂
Is set in advance to be substantially "zero", whereby the disc catcher 109 is connected to the soft magnetic core 112d.
, And fall by gravity to return to the original position, and the permanent magnet 1
08 again adsorbs. At this time, -P of the permanent magnet 108
₃ of magnetic force conveyed disk catcher 109 base 41
Although it is assisted that the disc catcher 109 falls immediately, the disc catcher 109 may be used only by its own weight without using the permanent magnet 108 in some cases. Then, as the disc catcher 109 returns to the transport base 41 side, the disc 4 sucked and floated by the flange 109a of the disc catcher 109 is placed on the tray 3 again.

<< Disc Playing Unit and Tray for Disc Playing Unit >> FIG. 13 is a schematic view showing the structure of the disc playing unit, and FIG. 14 is a perspective view showing a tray used for the disc playing unit. . FIGS. 15A and 15B are diagrams showing a state where a tray for a disk playing unit is pulled out to a disk transport unit and disks having different outer diameters are placed.

The disk playing unit 12 shown in FIG.
Reference numerals 0 and 121 are symmetrically disposed at the lowermost portion of the housing 2 shown in FIG.
Will be described.

The disc playing unit 120 is a turntable motor 123 to which the turntable 122 is fixed.
And an optical pickup 124 for reproducing or recording / reproducing a signal of the disk 4 and having a known structure, and a detailed description thereof will be omitted here.

A tray 5 is provided above the turntable 122 so as to be able to be pulled out in the directions of arrows M ₁ and M ₂ , and when the disk 4 is placed on the tray 5 by an operation described later, the tray 5 is shown in the figure. The disc 4 placed on the tray 5 is placed on the turntable 122 while the disc 4 is moved below the turntable 122 (in the directions of the arrows N ₁ and N ₂ ) by a lifting means that does not. Thereafter, the turntable 122 is rotated, and the optical pickup 124 rotates the disk 4.
Is to play. Depending on the type of the disk 4 to be used, the performance of the disk 4 may be either reproduction only or recording and reproduction, and can output audio information, video information, character information, and the like. Next, since the optical pickup 124 moves, the tray 5 for the disk playing unit shown in FIG.
Although the shape is slightly different from that shown in FIG. 4, the drawer structure of the tray 5 has the same technical idea.

That is, an opening 5a through which the optical pickup 124 shown in FIG. 13 can move is formed at the center of the tray 5 in the longitudinal direction. Also, surfaces 5b and 5c are formed with the outer diameter of the disk as a regulation standard so that two types of disks 4 having different outer diameters can be mounted, and a large outer diameter restricting portion 5d is formed on the surface 5b. On the other hand, a small outer diameter regulating portion 5e is formed on the surface 5c. Surface 5c is 1 more than surface 5b.
The height is a step lower, so that the surface 5b and the surface 5c are formed in a two-step concave shape. A CD having a large outer diameter of, for example, 12 cm can be placed on the surface 5b, and a CD having a small outer diameter of, for example, 8cm can be placed on the surface 5c. A detection hole 5 for detecting the outer diameter of the disk 4
f, 5g are formed, and the detection hole 5f is for a large outside diameter, and the detection hole 5g is for a small outside diameter. These detection holes 5
f and 5g are also detected by a photo sensor (not shown) in the transport base 41 similarly to the tray 3 described above.

At the tip, clamps 5h, 5h for pulling out the tray 5 from the disk playing units 120, 121 to the transport base 41 or returning to the original storage position.
h is formed in a “U” shape. This clamp part 5
h and 5h have the same shape as the clamps 3g and 3g (FIG. 4) of the tray 3, and are clamped by the tray pull-out mechanism 60 (FIG. 8), and the detailed description is omitted.

Further, a notch 5 is provided on both left and right sides of the tray 5 for detecting that the tray is for a disc playing unit.
i (only one side is shown). Then, when the tray 5 is pulled out to the transport base 41, as shown in FIG.
The lever 46 provided near the front surface 41e of the transport base 41 enters the notch 5i of the tray 5, and the micro switch 47 is turned "ON". In addition, the above-mentioned tray 3
In this case, the microswitch 47 is in the "OFF" state because the notch is not formed.

When the tray 5 is pulled out to the transport base 41, the disk suction mechanism 90 operates as described later. At this time, as shown in FIGS. 15A and 15B, the height position of the tray table 100 differs depending on the outer diameter of the disk. This is because when the disk 4 is held on the arm 91 side, the soft magnetic core 112 and the disk catcher 10
Tray table 10 so that the distance from the tray 9 is as small as possible.
0 moves very slightly according to the outer diameter of the disk. That is, as described above, the surface 5c on which the small outer diameter disk 4B is mounted is located one step lower than the surface 5b on which the large outer diameter disk 4A is mounted. Therefore, in the case of the large-diameter disk 4A, the tray table 100 projects upward to a high position as shown in FIG. 15A, and is in contact with the back surface of the large-diameter disk 4A. On the other hand, in the case of the small outer diameter disk 4B, as shown in FIG. 15B, the tray table 100 is at a lower position without protruding, and is in contact with the back surface of the small outer diameter disk 4B. The height of the tray table 100 is controlled by the cam wheel 1 as described above.
As shown in the figure, the small-diameter cam surface 104a and the large-diameter cam surface 104b are respectively slid.
