It is designed to engage with 0l ', and the return arm 10
The protrusion 10l "formed on the lower surface of l is adapted to engage with the rear end of the shaft rod 10n described above.
Since the projection 10l ″ is in contact with the rear end of the shaft rod 10n, the rotational force of the winding spring 10m is restricted to the state shown in FIG.
Further, the hook arm 10k has the projection 10k 'in contact with the projection piece 10l' of the return arm 10l so that the rotational force of the winding spring 10m is restricted to the state shown in FIG. Further, the movable body 10j is provided with a release pin 10o which comes into contact with the elastic engagement piece 9f of the tray 9 engaged with the projection 8a of the tray guide 8, 8'to release the engagement, from the shaft rod 10n. It is provided so as to project forward.

Further, guide grooves 15b for guiding the tray 9 are formed on both sides of the front-rear moving plate 15, and the tray 9 is formed on the upper front surface of the guide groove 15b as tray guides 8, 8'formed on the case 1. At the time of returning, there is formed a restricting piece 15c which is engaged with the returning arm 10l so as to freely rotate in the rear direction and not to rotate in the front direction.

Next, an operation for transferring the tray 9 based on the above-mentioned configuration will be described.

First, the state of each member before starting is as shown in FIG. That is, the rollers 6g ₁ and 6g ₁ ′ of the rotating arms 6g and 6g ′ have the guide grooves 1 of the rotating member 14 at the center position.
The projections 6l, 6l 'formed on the moving base 6 are inserted into the guide grooves 13c, 1c formed on the lower surface of the rotary plate 13.
It is inserted in 3c '. At this time, the switch S ₂ is turned on by the collar portion 14e.

In this state, when the motor 6i is energized and the gears 6f, 6f 'rotate clockwise as shown in FIG. 6, the rotating arm 6g remains inserted in the guide groove 14c of the rotating member 14, and The rotating arm 6g 'of the is formed by the guide groove 14c' of the rotating member.
Since it is detached from the rotating member 14, the rotating member 14 is rotated clockwise by the rotating arm 6g. On the other hand, the protrusion 6l remains inserted in the guide groove 13c, and the other protrusion 6l 'is
Separate from 13c '.

Therefore, the rotating plate 13 is rotated counterclockwise with respect to the moving base 6 via the rotating disk 12 with the engaging portion between the projection 6l and the guide groove 13c as a fulcrum. When the switch S ₃ rotating member 14 is rotated approximately 90 degrees is turned on by the flange portion 14e, the rotation of the rotating plate 13 is cut off energization to the motor 6i is stopped at the position shown in Figure 6.

Further, when the motor 6i is rotated in the opposite direction to the above,
The gears 6f, 6f 'rotate in the direction opposite to that shown in FIG. 6, so that the rotating member 14 is rotated counterclockwise and the projection 6l' and the guide groove 13 are rotated.
The rotating plate 13 is rotated clockwise with the engaging portion with c'as a fulcrum.

When the rotating plate 13 is rotated counterclockwise or clockwise in this manner, the rotating plate 13 faces the tray 9 inserted in the tray guides 8 and 8'of the case 1.

As described above, when the switch S ₁ is turned on and the rotating plate 13 is stopped, the motor 10a is energized and the two worm 1
0b is rotated. When the worm 10b is rotated, the pair of gears 10c is rotated, and the large pulley 10f is rotated in the direction of the arrow in FIG. 7 via the belt 10e wound around the pulley formed on the pair of gears 10c. Here, the worm 10b has two threads because the pair of gears 1 meshed with the worm 10b
This is to rotate 0c in synchronization. When each large pulley 10f is rotated, the rotation arm 10g fixed to each rotation is rotated in the same direction as the large pulley 10f, so that the control arm 10h and the moving arm 10i are rotated integrally.
Here, when the moving arm 10i is rotated counterclockwise,
Since the tip of the moving arm 10i is engaged with the protrusion 13e of the rotating plate 13, the front-rear moving plate 15 is guided by the guide bar 13d to move forward, and is guided by the tray guide 8 or 8'of the case 1. Close to the tray 9.

On the other hand, when the pair of control arms 10h are respectively rotated in the same direction as the rotation arms 10g, the moving body 10j engaged with the tip of the control arm 10h is guided by the guide bar 15a to move forward. Then, the moving body 10j moves forward, and the release pin 10o abuts on the elastic engagement piece 9f of the tray 9 to release the engagement with the projection 8a of the tray guide 8 or 8'just before the completion of the advancement. The shaft rod 10n comes into contact with the ridge 9e of the tray 9 and retreats against the spring force of the spring 10n 'to rotate the return arm 10l against the winding spring 10m, and the hook arm 10k moves toward the tray 9. After once contacting the hook 9g and rotating against the spring force of the coil spring 10m, it is engaged with the hook 9g (No. 9).
Figure).

When a switch (not shown) detects this forward end state,
After stopping the motor 10a once, the motor 10a is reversely rotated. Due to this reverse rotation, the front-rear moving plate 15 retracts and the moving body 10j also retracts due to the opposite operation.
Then, when the moving body 10j is retracted, the hook arm 10k is engaged with the hook 9g of the tray 9, and the release pin 10o abuts on the elastic engaging piece 9f of the tray to project the tray guide 8 or 8 '. Since the engagement with 8a is released, the tray 9 is moved along with the front-rear moving plate 15 while pulling out the tray 9 from the tray guide 8 or 8'and retracting it into the guide groove 15b of the front-rear moving plate 15 as the moving body 10j retreats. The body 10i returns to the initial position (Figs. 10 and 12).

In the returning operation of the moving body 10j, the returning arm 1
Although 0l abuts on the restricting piece 15c on the guide groove 15b in the front-rear moving plate 15, the restricting piece 15c freely rotates backward, so that the return arm 10l passes while rotating the restricting piece 15c. .

In this way, when the front-rear moving plate 15 and the moving body 10j return to the initial position, the switch (not shown) operates and the motor 10a
The rotation plate is energized at the same time as the rotation of the motor 6i is stopped.
When 13 is returned to the neutral position shown in FIG. 5 by the reverse operation to the above, and the switch S ₂ is turned on, the power supply to the motor 6i is cut off and stopped.

Thus, when the switch S ₂ is turned on, the motor is turned on again.
10a is energized, the front-rear moving plate 15 moves forward, and the moving body 10j
Will also move forward. By the forward movement of the moving body 10j, the tray 9 is moved from the guide groove 15b to the disc player 11 or 1 described later.
The tray 9 advances while being inserted into the guide groove 111k ₃ formed in 1 '. Then, near the final advance of the moving body 10j, the return arm 10l comes into contact with the restricting piece 15c, but here, since the restricting piece 15c cannot rotate in the forward direction, the return arm 10l has the spring force of the winding spring 10m. It is rotated against. When the return arm 10l is rotated, the protrusion 10 of the return arm 10l is rotated.
Since the protrusion 10k 'of the hook arm 10k engaged with l'is pulled, the hook arm 10k is also rotated in the same direction as the return arm 10l against the spring force of the winding spring 10m, and thus the hook arm 10k is rotated. The engagement between 10k and the hook 9g of the tray 9 is released. When the engagement between the hook arm 10k and the hook 9g is released, the tray 9 is moved to the disc player 11 or 1 by the shaft rod 10n which is biased by the spring 10n '.
It is pushed to the end of 1'guide groove 111k ₃ and
When the back-and-forth moving plate 15 and the moving body 10j move to the end, the electric power supply to the motor 10a is cut off and the movement is stopped in the same manner as described above (FIGS. 11 and 13).

When the movement is stopped, the motor 10a starts reverse rotation, so that the front-rear moving plate 15 and the moving body 10j start retreating. Because away from the resilient locking piece 9f by releasing pin 10o by retraction of the mobile 10j, elastic locking pieces 9f is engaged with the hook 111k ₄ formed in the guide groove 111k ₃ of displayer 11 or 11 ' Together with the shaft rod 10n, the spring 10
The tray 9 is continuously pushed by the spring force of n '. Therefore,
The tray 9 is set in the disc player 11 or 11 '.

When the reproduction by the disc player 11 or 11 'is completed, the tray 9 is moved to the tray rail 8 of the case 1 described above.
Alternatively, the tray 9 returned to the tray transfer means 10 by an operation similar to the operation of taking out the disk player 8 ', and the tray 9 returned to the tray transfer means 10 is the disk player 11 or 11'.
It is returned to the tray rail 8 or 8'by the same operation as the transfer to.

FIG. 14 is a plan view showing the transfer state of the tray 9.

Next, the disc players placed above and below the case 1
The structure of 11 or 11 'will be described with reference to FIGS. Since the disc players 11 and 11 'have the same structure, only the disc player 11 in the upper stage will be described.

Thus, as described above, the pickup base 111f is raised while the slide plate 111g moves from the solid line state to the phantom line state in FIG.
When 1d lifts the disk D on the tray 9 and reaches the position of the imaginary line, the tip of the moving plate 111l moves the tray moving frame.
Abut the 111k hanging piece 111k ₂ . When the slide plate 111g is moved from this state to the position shown in FIG. 16, the tray moving frame 111k is moved against the spring force of the spring 111k ₁ along with this movement, and moves to the end of the box 111a. Stop (Fig. 19). The extra movement amount of the slide plate 111g is absorbed by the spring 111l ₁ . Therefore, since the outer peripheral edge of the tray 9 is not located within the movement range of the pickup 111e, the size of the tray 9 can be made substantially the same as the size of the disc D.

A tray guide 111k similar to the tray guide 8 attached to the case 1 is provided on both left and right sides of the tray moving frame 111k.

The disk D is removed from 111d ₅ and inserted into the outer peripheral portion 113m ₁ of the position regulating plate 113m, and the disk D is positioned by the position regulating plate 113m. At the point of time when the rise of the turntable 111d is completed, since the sandwich pressed disk D turntable body 111d ₃ is toward the disk pressing plate 113k of the clamper 113, the turntable 111d motor
By driving the 111d _2, the disk D is to rotate (Figure 26).

The configuration of each part and the operation of each part are as described above. Next, the overall operation will be described.

First, when a desired program (for example, a song for karaoke) is selected on the operation unit (not shown), the control unit (not shown) determines on which disc D the selected song is recorded, and the moving base 6 is moved. By moving, the guide groove 15b of the tray transfer means 10 is aligned with the tray guides 8 and 8'in which the disk D is stored.

Next, the motor 6i is driven to rotate the rotary plate 13 in the left-right direction to the tray guide 8 or 8'on the side where the desired disk D is housed, and further the motor 10a is driven to drive the front-rear moving plate 15. Of the tray guide 8 or 8'and the elastic engagement piece of the tray 9 by the release pin 10o.
The engagement with 9f is released, and the hook arm 10k is engaged with the hook 9g of the tray 9. And the motor 10
The tray 9 is pulled out from the tray guides 8 or 8'by rotating a in the reverse direction and is drawn into the guide groove 15b, and the motor 6i is rotated in the reverse direction to return the rotating plate 13 to the front position.

Then, the moving base 6 is moved to the position of the disc player 11 or 11 'located above or below (if
Lower player 1 when upper player 11 is playing
1 ', or to the upper player 11 when the lower player 11' is playing), the guide groove 15b of the tray transfer means 10 is moved to the tray of the lower disc player 111 in the disc player 11 or 11 '. Match with Guide 111k ₃ . In this state, advancing the longitudinal movement plate 15 by driving the motor 10a for transferring the tray 9 from the guide groove 15b in the tray guide 111k _3. The tray 9 is an elastic engaging piece.
9f is engaged with the projection 111k _4, and the tray 9 is fixed to the tray guide 111k ₃ by the pressing force of the pressing plate 111n.

Then, the slide plate 111g is moved by a motor (not shown) to raise the turntable 111d to lift the disc D on the tray 9 and clamp the disc D with the clamper 113, and after positioning with the turntable 111d, Further, the movement of the slide plate 111g moves the tray movement frame 111k to the right. Therefore, the tray 9 is retracted from the movement range of the pickup 111e.
The lower surface information of the disc D can be read as the 111e moves.

Further, when reading the upper surface information of the disc D, first, the motor 112b is driven to lower the position regulating plate 113m first, and then the slide plate 111g moves to clamp the disc D and position it on the clamper 113 side. After that, the pickup 112d moves to read the upper surface information of the disc D.

The disc D, from which information has been read, is returned to the tray guides 8 and 8'while being placed on the tray 9 by an operation opposite to the above-mentioned operation.

〔The invention's effect〕

As described above, according to the present invention, the outer diameter of the tray is made substantially equal to the diameter of the disk and the size of the tray is reduced, so that the autochanger device can be downsized.

Further, since a long hole longer than the movement range of the pickup of the disc player is provided within the range of the disc mounting surface in the radial direction of the disc mounting surface of the tray and the periphery of the long hole is connected, the periphery of the long hole of the tray is connected. Will be connected, and the strength of the tray can be secured.

Furthermore, the tray of the present invention has an outer dimension substantially equal to the diameter of the accommodated disc, and the circular disc mounting surface is at least longer than the entire movement range of the pickup.
Moreover, since a long hole consisting of a complete hole whose entire circumference is connected is located in the disk mounting surface and is bored in the radial direction of the disk mounting surface, the tray retracting means causes the tray to serve as the axis of the turntable. When moving in the orthogonal direction, the pickup traces the entire signal recording surface of the disc simply by moving the pickup by a predetermined distance so that the entire movement range of the pickup fits within the long hole formed in the disc mounting surface. Even if the outer dimension of the tray is reduced to about the same as the diameter of the disc, the outer peripheral edge of the tray interferes with the pickup and the recording signal on the outermost periphery of the disc can be read out as in the conventional autochanger device. It is possible to eliminate things that can not be done.
