Combined moving arm 1
The control arm 1 is guided by guide bars 15a, two of which are formed on the left and right sides of the longitudinal movement plate 15.
The moving body 10j with which the tip of 0h is engaged, and the moving body 10
The hook arm 10 is rotatably supported on a pin 10j' implanted in j, and the return arm lO! And the hook arm 10k, return arm 10! The movable body 10j is supported by a coiled spring 10m that biases clockwise on the left side and counterclockwise on the right side, and a spring 10n' that is slidably supported on the movable body 10j.
The shaft rod 10n is spring-biased in the forward direction of the shaft. The projection 10 formed on the upper surface of the hook arm 10 is indicated by the return arm 10I!
Projection piece 10 formed on the lower surface of ! '', and a protrusion 10j2'' formed on the lower surface of the return arm 10n engages with the rear end of the shaft 10n. Therefore, the return arm 101 Protrusion 1
0! Since " is in contact with the rear end of the shaft rod 10n, the rotational force by the coiled spring 10m is regulated to the state shown in FIG.
Due to the contact with the protruding piece 101' of Offfi, the rotational force of the coiled spring 10m is also regulated to the state shown in FIG. 7. Further, the moving body 10j includes a tray guide 8.
, 8' is provided to protrude forward from the shaft Ion.

Furthermore, guide grooves 15b for guiding the tray 9 are formed on both sides of the back and forth moving plate 15, and the guide grooves 15b
5b is provided with the return arm 1 when returning the tray 9 to the tray guides 8, 8' formed in the case 1.
0I! A regulating piece 15c is formed so that it can rotate freely in the rear direction and cannot rotate in the front direction.

Next, the operation for transferring the tray 9 based on the above configuration will be explained.

First, the states of each member before starting are as shown in the fifth article. That is, the rollers 6gs and 6g1' of the rotating arm 6g+6g' are the rotating member 1 at the center position.
The protrusions 61, . 61' are inserted into guide grooves 13c, 13c' formed on the lower surface of the rotating plate 13. Note that at this time, the switch S2 is turned on by the alligator portion 14e.

In this state, the motor 61 is energized and the gear 6 f
, 6f' rotate in the clockwise direction shown in FIG. Since it is removed from the guide groove 160', the rotating member 14 is rotated clockwise by the rotating arm 6g.

On the other hand, protrusion 6I! .

remains inserted into the guide groove 13c, and the other protrusion 61' separates from the guide groove 13c'.

Therefore, the rotating plate 13 is connected to the rotating disk 12 with respect to the movable base 6.
Protrusion 6I through! , and the guide groove 13c as a fulcrum and rotated counterclockwise. And the rotating member 1
4 is rotated approximately 90 degrees and the switch S2 is turned on by the collar 14e, the power to the motor 61 is cut off and the rotating plate 1
3 stops at the position shown in FIG.

Further, when the motor 61 is rotated in the opposite direction to that described above, the gears 6 f and 6 f' are rotated in the opposite direction to that shown in FIG. ! The rotating plate 13 is rotated clockwise using the engagement portion between the guide groove 13C' and the guide groove 13C' as a fulcrum.

When the rotary plate 13 is rotated counterclockwise or clockwise in this manner, the rotary plate 13 comes into a state facing the tray 9 inserted into the tray guides 8, 8' in the case 1.

As mentioned above, the switch S3 is turned on and the rotating plate 13 is turned on.
When the motor 10a stops, the motor 10a is energized and the two worms 10b are rotated. When the worm 10b is rotated, the pair of gears 10c are rotated, and the large pulley 10f is rotated in the direction of the arrow in FIG. 7 via the belt loe wound around the pulleys formed on the pair of gears 10c. Here, the reason why the worm 10b has two stripes is because the worm 10b has two strips.
This is to synchronize and rotate the pair of gears 10c that are meshed with each other. When each large pulley 10f is rotated, the rotating arm Log fixed thereto is rotated in the same direction as the large pulley 10f, thereby rotating the pair of control arms 10h and moving arm 10i. here,
When the movable arm 101 is rotated counterclockwise, since the tip of the movable arm 1.10i is engaged with the protrusion 13e of the rotary plate 13, the forward and backward movable plate 15 is moved toward the guide bar 13d.
The tray 9 moves forward while being guided by the tray guide 8 or 8' of the case 1.

On the other hand, the pair of control arms 10h each have a rotating arm of 10 g.
When the control arm 10h is rotated in the same direction, the movable body 10j engaged with the tip of the control arm 10h is guided by the guide bar 15a and moves forward. Then, the movable body 10j moves forward, and just before the end of its forward movement, the release pin 10o comes into contact with the elastic engagement piece 9f of the tray 9 to release the engagement with the protrusion 8a of the tray guide 8 or 8'. The shaft rod Ion contacts the projection 9e of the tray 9 and retreats against the spring force of the spring 100', causing the return arm 10j2 to rotate against the coil spring 10m. Once it contacts the hook 9g and rotates against the spring force of the coiled spring 10m, it is engaged with the hook 9g (FIG. 9).

When a switch (not shown) detects this forward end state,
After the motor 10a is once stopped, the motor 10a is rotated in the reverse direction. Due to this reverse rotation, the back-and-forth movable plate 15 retreats, and the movable body 10j also retreats by an operation opposite to that described above. Then, when the moving body 10j retreats,
The hook arm 10k is engaged with the hook 9g of the tray 9, and the release pin 100 contacts the elastic engagement piece 9f of the tray 9 to release the engagement with the protrusion 8a of the tray guide 8 or 8'. Therefore, as the movable body 10j moves backward, the tray 9 is pulled out from the tray guide 8 or 8' and drawn into the guide groove 15b of the longitudinal movement plate 15, while the longitudinal movement plate 1 is pulled out.
5 and the moving body 10j return to their initial positions (Fig. 10,
Figure 2).

In addition, in the return operation of the movable body 10j, the return arm 10ffi comes into contact with the regulation piece 15c on the guide groove 15b of the forward/backward moving plate 15, but since the regulation piece 15c freely rotates in the rear direction, the return The arm 101 passes through the regulating piece 15c while rotating it.

In this way, when the back-and-forth moving plate 15 and the movable body 10j return to their initial positions, a switch (not shown) operates to stop the rotation of the motor 10a, and at the same time, energizes the motor 61 to move the rotating plate 13 as described above. is returned to the neutral position shown in FIG. 6 by the reverse operation, and when the switch S2 is turned on, the power supply to the motor 61 is cut off and stopped.

In this way, when the switch S2 is turned on, the motor 10a is energized again and the back-and-forth moving plate 15 moves forward, and the movable body 10j also moves forward. As the moving body 10j moves forward, the tray 9 moves forward without being inserted from the guide groove 15b into a guide groove 111ka formed in a disc player 11 or 11', which will be described later. Then, near the end of the forward movement of the movable body 10j, the return arm 101 comes into contact with the restriction piece 15c, but at this point, the restriction piece 15c cannot rotate forward, so the return arm 10! is coiled spring 1
It is rotated against a spring force of 0 m.

Return arm 10I! , is rotated, the return arm 1
0! Projection piece 10I! , ' hook arm 1 engaged with '
0 is pulled to the protrusion 10, so the hook arm 1
The arm 10I returns to zero against the spring force of the coiled spring 10m.
! , and therefore the hook arm 10
The connection between the tray 9 and the hook 9g is released. When the hook 9g is disengaged from the hook arm 10, the tray 9 is moved to the disc player 11 or 1 by the shaft 10n biased by the spring 10n'.
When the motor 10a is pushed to the end of the guide groove 111ka of the guide groove 1' and the moving body 10j is moved to the end, the power to the motor 10a is cut off and the movement is stopped in the same way as described above (Fig. 11, Figure 13).

Then, when the movement is stopped, the motor Oa starts rotating in the opposite direction, so that the back and forth moving plate 15 and the transfer body 10j start moving backward. Due to this retreat of the transfer body 10j, the release pin 10
Since the elastic locking piece 9r is further separated by o, the elastic locking piece 9f is engaged with the hook 1llk4 formed in the guide groove 111ka of the disc player 11 or 11', and the shaft rod Ion is engaged with the spring 10n'. The tray 9 is continued to be pushed by the spring force. Therefore, the tray 9 is set in the disc player 11 or 11'.

When the playback by the disc player 11 or 11' is finished, the tray 9 is returned to the tray transfer means 10 by the same operation as the operation of taking it out from the guide rail 8 or 8' of the case 1, and the tray 9 is returned to the tray transfer means 10.
The tray 9 returned to 0 is connected to the disk player 11 described above.
Alternatively, it is returned to the guide rail 8 or 8' by the same operation as the transfer to the guide rail 8 or 11'.

Further, FIG. 14 is a plan view showing the state in which the tray 9 is transferred.

Next, the structure of the disc player 11 or 11' arranged above and below the case 1 will be explained with reference to FIGS. 15 to 26. Note that since the disc players 11 and 11' have the same configuration, only the upper stage disc player 11 will be described.

The disc player 11 has a pickup 1 so that it can read information recorded on both sides of a disc D supported by a turntable and a clamper, which will be described later.
11e are arranged above and below the disk D. That is, as shown in FIGS. 15 and 16, they are arranged at a desired interval, and the upper disc player 112 is attached to the lower disc player 111.

The specific structure of the lower disc player 111 will be described below with reference to FIGS. 15 to 19.

Reference numeral 111a is a box fixed to the case 1, and support shafts 111b are connected from two places of the box 111a.

111c is hanging down. 111f is a known turntable 111d that clamps the disk D between a clamper to be described later, and a pickup 111e that moves horizontally toward and away from the turntable 111d and reads information on the disk D is attached. A fixed roller 111f1 that contacts the support shaft 111b at one end and a movable roller 111f2 that contacts the support shaft 111b elastically by a spring 111Is are attached to the pickup base, and the other end is attached to the support shaft 111b. Two fixed rollers 111fs and 111f4 that come into contact with 111c,
A movable roller 1llfa is attached which is elastically abutted by a spring 111fs. Therefore, the pickup base 111f has the above-mentioned rollers 1llfx~
1llfs, it is supported to be movable only vertically.

Reference numeral 111g is a slide plate that is slidably attached by rollers 1llat arranged on the front and rear surfaces of the box 111a. , Two guide holes (not shown) similar to those described above are formed in the rear slide plate. Furthermore, a rack 111g2 is formed on a part of the upper edge of the slide plate 111g, and a gear 111h1 fixed to both ends of a rotating shaft 111h rotated by a motor (not shown) is meshed with this rack 111g2. Therefore, when the motor rotates and the gear 111hs rotates,
The slide plate 111g moves to the left as shown in FIGS. 15 and 16.

A rotating arm 1111 whose one end is pivotally supported is attached to the pickup base 111f, and a pin 111i* protruding from approximately the center thereof is inserted into the guide hole g1 of the slide plate 111g. And rotating arm 1
A spring 111i2 is stretched between the tip of the pickup base 111 and the pickup base 111f. Therefore, when the slide plate 111g moves as described above, the rotating arm 1111 moves upward as shown in FIG.
It is raised by the spring force of i2. As a result, the turntable 111d raises the disk D on the tray 9, which will be described later.

Guide bars 111 are provided at the front and rear upper edges of the box 111a.
3 is arranged, and a tray moving frame 111k is movably guided by this. A spring 111 is tensioned between the tray moving frame 111 and the box 111a, and constantly biases the tray moving frame 111k to the left in FIGS. 18 and 19. Further, on the front and rear lower surfaces of the tray moving frame 111, there is a moving plate 111, which will be described later. 2 is formed on the hanging piece 111 that comes into contact with. Moving plate 11
11 is attached to the slide plate 111g described above so as to be horizontally movable, and a spring 111At is stretched between the slide plate 111g and constantly biases the movable plate 111ρ to the right. As described above, while the slide plate 111g moves from the solid line state to the imaginary line state in FIG. When the position of the virtual line is reached, the moving plate 111! The tip of the hanging piece 11 is attached to the tray moving frame 111.
1 touches 2. When the slide plate 111g moves from this state to the position shown in FIG. 16, the tray moving frame 111 is moved against the spring force of the spring 1llki and moved to the end of the box 111a. Stop (Figure 19). Note that the extra movement amount of the slide plate 111g is absorbed by the spring 111j2t.

Therefore, the tray 9 is within the movement range of the pickup 111e.
Since the outer peripheral edge of the disk D is not located, the size of the tray 9 can be made to be approximately the same size as the disk D.

A tray guide 1llka similar to the tray guide 8 attached to the case 1 is attached to both left and right sides of the tray moving frame 111 described above, and the tray transfer means 10 described above is attached.
When the tray 9 transferred by is inserted, a + mark is formed on the protrusion 111 that engages with the elastic retaining piece 9f of the tray 9. Further, on the back side of the tray moving frame 111, a pair of L-shaped rotating push-out plates 111m each having a spring Il1mt stretched between one end and the tray moving frame 111 are rotatably attached. The other end is brought into contact with the tip of the protruding piece 9e of the tray 9, and is constantly biased by the spring in the direction of pushing out the tray 9. Further, one end of the tray moving frame 111k is inserted into the 1-ray guide 111ka, and a spring 1l is inserted between the other end and the tray moving frame 111.
An L-shaped pressing plate 111n with lrz stretched thereon is attached to press the side surface of the protruding piece 9e of the tray 9 inserted into the tray guide 1llka, thereby preventing the tray 9 from shaking in the left-right direction. Therefore, the tray 9 is inserted into the tray guide 5, and the elastic engagement piece 9 of the tray 9
In the state where f is engaged with protrusion 111 at 4,
The pressing plate 111n presses the side surface of the protruding piece 9e of the tray 9 to prevent rattling in the left and right direction, and also
When the elastic engagement piece 9f and the protrusion 111ka are disengaged by 0, the rotating push-out plate 111m1 acts to push out the tray 9. In addition, the rotating extrusion plate 111m
1 prevents the tray 9 from rattling in the front-rear direction when engaged.

Next, the configuration of the upper disc player 112 will be explained with reference to FIG. 20.

The upper disc player 112 is also the lower disc player 1.
Similarly to 11, a clamper 113 is mounted in a box 112a so as to be vertically movable via a motor 112b and a reduction gear 112C, and a pickup 112d is mounted so as to be horizontally movable. Therefore, the information on the disc D held between the turntable 1lld and the clamper 113 in the lower disc player 111 can be read by the pickup 112d.

By the way, if disc D is a video disc, 2
Since the disc is made of two discs pasted together, there may be a misalignment between the center hole of the lower disc and the center hole of the upper disc. Therefore, when the disk is centered by the turntable 111d and clamped by the clamper 113, the turntable 111d is not necessarily aligned with the center hole of the upper disk.Therefore, in this state, information is read by the upper pickup 112d. In this case, the disk D is attached to the pickup 112d.
This may result in center runout, making tracking difficult. Therefore, in this embodiment, when reading the upper disk, the disk D is held between the turntable 111d and the center of the disk D is aligned by the clamper 113.

Details of this clamper 113 will be explained below with reference to FIGS. 21 to 26.

The flat plate portion 113ez is fitted into the cut groove L13d2. In this state, the pin 113h is inserted through one of the elongated holes 113bs formed on the opposite surfaces of the pipe 113b, and the elongated hole 1 of the hollow shaft 113d3 and the shaft rod 113e is inserted.
The pin 113h penetrates through the elongated hole 113bt of the pipe 113b via the pin 13ea, and both ends of the pin 113h protrude. This results in
The end protruding from the pipe 113b contacts the cam base 113C2 of the gear 113C, the hollow shaft 113d and the shaft rod 113e are connected by a pin 113h, and the shaft rod 113e is connected to the spring 113 with respect to the hollow shaft 113d.
They are spring-biased in the direction of separation by f.

Further, the hollow shaft 113d is biased upward by a spring B against the pipe 113b by a spring 113g.

Reference numeral 1131 is a support that is pivotally supported to be vertically movable with respect to the pipe 113d, and is constantly biased downward by a spring 113j. 113 is a disk pressing plate rotatably attached to the receiving plate 1131 via a bearing 113ix, 113I! , is the shaft rod 113

protrudes downward.

The turntable 111d has a built-in motor 111d2.
The turntable body 111da is rotated by a spring 1lld in the center of the turntable body 111ds.

A position regulating plate 111d5 is attached which is biased upward by a spring.

The operation of holding and reproducing the disc D between the turntable 111d and the clamper 113a will now be described.

Tray guide 111 for tray 9 to tray moving frame 111
When a lower surface playback command is issued for the disc D on the tray 9 while being guided by the disc D on the tray 9, the slide plate 111g moves and the pickup head 111f rises, causing the turntable to move. 111d rises. When the turntable 111d is raised, the position regulating plate 111ds enters from the lower surface of the disk D and performs positioning with respect to the turntable 111d. Furthermore, when the turntable 111d rises, the turntable main body 111da pushes up the lower surface of the disk D toward the disk pressing plate 113 of the clamper 113a, so that the disk D
a and the disk pressing plate 113. Therefore, in this state, the motor 1ll of the turntable 111d
Since the disk D is rotated by driving d2, information is read as the pickup 111e moves (FIG. 23).

Next, the reproduction operation for the upper surface of the disc D will be explained. When the disc D is placed on the tray 9 (if the disc D is held between the turntable 111d and the clamper 113a, the disc D is placed on the tray 9 by the reverse operation to the above-mentioned operation). ) When the top surface regeneration command is issued, the motor 112b
is driven and the final gear 112c is driven via the reduction gear 112c.
1 is rotated. As the final gear 112c1 rotates, the gear 113C rotates the operating pin 113c of the gear 113c.
Since the pin 113h is rotated until it contacts the switch 113at, the pin 113h is lowered by the cam base 113c.

Therefore, the hollow shaft 113d and the shaft rod 113e are lowered against the spring force of the spring 113g, and the position regulating plate 11
The 1 m long shaft tube 113m2 now faces into the hole of the disk D (FIG. 24).

Next, the slide plate 111g starts to move and the turntable l1ld starts to rise by the same operation as the lower surface playback operation of the disk D described above, but in the middle of the rise, the position regulating plate 113m is lowered as described above. From, the fixed central axis 111d of the turntable 111d
1 is inserted into the shaft tube 113m2, the position regulating plate 111d5 enters the hole of the disc D, and the upper surface of the turntable body 111da abuts the lower surface of the disc D (FIG. 25). Furthermore, turntable 111
When d rises, the center of the position regulating plate 111d5 becomes the axis tube 113m of the position regulating plate 113m in the clamper 113.

11da is further pushed up, so the disc D is raised by the turntable body 111da, and the disc D
The hole passes through the position regulation plate 111 ds and connects to the position regulation plate 1.
The disk D is inserted into the outer peripheral portion 113m1 of 13m, and the disk D is positioned by the position regulating plate 113m. Then, at the time when the turntable 111d has finished rising, the turntable main body 111da is moved to the clamper 113.
disk press +disk D toward ff1113k
Since the turntable 111d is pressed and held, the turntable 111d
By driving the motor 111d2 of the disc D
is rotating (Fig. 26).

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

First, when a desired program (for example, a song for karaoke) is selected using an operation section (not shown), the control section (not shown) determines which disk D the selected song is recorded on, and moves the movable base 6. The guide groove 15b of the tray transfer means 10 is brought into alignment with the tray guides 8, 8' in which the disk D is stored.

Next, the motor 61 is driven to move the rotary plate 13 to the tray guide 8 or 8' on the side where the desired disk D is stored.
Further, the motor 10a is driven to move the forward/backward moving plate 15 forward, and the release pin 10o releases the protrusion 8a of the tray guide 8 or 8' and the tray 9.
is released from the elastic retaining piece 9f, and the hook 9g of the tray 9 is engaged with the hook 9g of the tray 9. Then, the motor 10a is reversely rotated to pull out the tray 9 from the tray guide 8 or 8' and into the guide groove 15b, and the motor 61 is reversely rotated to remove the rotating plate 13.
Return to the front position.

Next, move the movable base 6 to the position of the disc player 11 or 11' located above or below (if the upper player 11 is playing, move it to the lower player 11', When the player 11' is playing, it moves to the upper player 11), and the guide groove 15b of the tray transfer means 10 is aligned with the tray guide 1llka of the lower disc player 111 in the disc player 11 or 11'. In this state, the motor 10a is driven to move the back and forth moving plate 15 forward to transfer the tray 9 from the guide groove 15b to the tray guide 111. The tray 9 has an elastic retaining piece 9f with a protrusion 111.
4, and the tray 9 is fixed to the l-ray guide 1llka by the pressing force of the pressing plate 111n.

Next, the slide plate 111g is moved by a motor (not shown).
moves to raise the turntable 111d and remove the tray 9.
After the upper disk D is lifted and clamped between the clamper 113 and positioned by the turntable 111d, the tray moving frame 111k is further moved to the right by the movement of the slide plate 111g. Therefore, since the tray 9 is retracted from within the movement range of the pickup 111e, information on the bottom surface of the disk D can be read as the pickup 111e moves.

In addition, when reading the upper surface information of the disk D, the motor 112b is driven and the position regulating plate 113m is first lowered, and then the slide plate 111g moves to clamp the disk D and position it on the clamper 113 side. After that, the pickup 112d moves and picks up the disc D.
The information on the top of the screen can be read.

It should be noted that the disk D from which the information has been read is returned to the tray guides 8, 8' while being placed on the tray 9 by an operation opposite to that described above.

〔Effect of the invention〕

As described above, the present invention has a tray that rotates to a position facing each tray guide, moves back and forth at the facing position to pull out a tray in the tray guide, and inserts the pulled out tray into the tray guide. Since the transfer device is configured, the depth of the case can be narrowed and the overall size of the device can be reduced, and since the operation of the tray transfer device is relatively simple, the operation is smooth and
This method has the following effects: it can be carried out quickly, there are few failures, the tray transfer time is shortened, and the time required for regeneration can be shortened.
