Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a disc autochanger device that stores a large number of discs such as video discs and compact discs, and selects and plays a desired disc by external operation. .

[Conventional technology]

A conventional disk autochanger device of this type has a plurality of pairs of guide grooves formed on one side of a case or both sides of a conveying means, and a tray containing a disk is inserted into each guide groove so as to be freely drawn out.

On the other hand, a player for playing discs is disposed above or below the case, and a transport means that reciprocates between the player and the trays arranged in multiple stages pulls out the discs together with the trays and transports them to the player. The disc was configured to be played by a player.

[Problem to be solved by the invention]

By the way, in the above-mentioned conventional disc autochanger device, the discs are arranged vertically in a row with respect to the case or on both sides with the conveyance means in between, so there is a limit to the number of discs that can be stored, and the case is closed. There was an inconvenience that the width became unusually large. In addition, in order to pull out a tray from the tray guide and transfer the pulled out tray to the disc player, the depth of the tray stored in the tray guide and the depth of the tray pulled out from the tray guide must be This requires a depth that is twice as long as the length, and the depth of the case also increases. Therefore, if you try to store a large number of discs while limiting the width and depth, there is no way to stack them vertically, which increases the height of the case, which is troublesome when storing new discs, and also makes it difficult to move the transport means. Since the distance is long, it takes a long time to select a disc and set it in the player, resulting in a problem that the music selection time becomes long.

[Purpose of the invention]

The present invention is intended to solve the above-mentioned problems, and its purpose is to accommodate twice the amount of discs stored in a conventional case without changing the width, depth, and height of the case from the conventional case. In addition, it is an object of the present invention to provide a disc autochanger device that allows a disc transporting means to set a disc in a player at the same speed as before.

[Summary of the invention]

The present invention aims to achieve the above-mentioned object, and its gist is that a pair of left and right tray guides for storing trays are arranged in a V-shape facing a tray transfer means, and The center of rotation of the means is arranged inside the intersection of the V-shape, thereby reducing the depth of the case.

" is in contact with the rear end of the shaft rod Ion, so that the rotational force due to the winding spring 10m is regulated to the state shown in FIG. 7, and
The hook arm 10 has a return arm 10n on the protrusion 10.
Due to the contact with the protruding piece Ion', the coiling force is 10 m.
Similarly, the rotational force caused by the rotational force is regulated to the state shown in FIG. Further, a release pin 100 is provided on the movable body 10j from the shaft rod Ion to abut on the elastic engagement piece 9f of the tray 9 that is engaged with the protrusion 8a of the tray guides 8, 8' to release the engagement. It is installed so as to protrude from the front.

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.
A regulating piece 15c is formed in the rear direction where it engages with 01, and is attached so that it can rotate freely and cannot rotate in the front direction.

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

First, before starting the engine, each member is in a state as shown in FIG. That is, the roller 6gts6gt' of the rotating arm 6gt6g' is located at the center of the rotating member 14.
The protrusions 6I! are inserted into the guide grooves 14c, 14c' of the movable base 6 and formed on the movable base 6! ,,6I! ,' is rotating plate 1
3 are inserted into guide grooves 13c and 13c' formed on the lower surface of the holder. Note that at this time, the switch S2 is turned on by the collar portion 14e.

In this state, the motor 61 is energized and the gears 6f, 6
When f' rotates clockwise as shown in FIG. 6, the rotating arm 6g remains inserted into the guide groove 14c of the rotating member 14, and the other rotating arm 16f' is inserted into the guide groove of the rotating member 14. 160', the rotating member 14 is rotated clockwise by the rotating arm 6g. On the other hand, the protrusion 61 remains inserted into the guide groove 13c, and the other protrusion 6ρ' is removed from the guide groove 130'.

Therefore, the rotating plate 13 is connected to the rotating disk 12 with respect to the movable base 6.
Protrusion 6 through! The guide groove 13c is rotated counterclockwise about the engagement portion between the guide groove 13c and the guide groove 13c as a fulcrum. Then, when the rotating member I4 is rotated approximately 90 degrees and the switch S2 is turned on by the collar portion 14e, the power to the motor 61 is cut off and the rotation of the rotating plate 13 is stopped at the position shown in FIG.

Furthermore, when the motor 6i is rotated in the opposite direction to that described above, the gears 6f and 6f' 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 130' and the guide groove 130' 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 10e wound around the pulleys formed on the pair of gears 10c. Here, the reason why the worm 10b has two threads is that the corresponding ohm 10b
This is to synchronize and rotate the pair of gears 10c that are meshed with each other. When each of the large pulleys 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 IOi. . Here, when the movable arm 101 is rotated counterclockwise, since the tip of the movable arm 10i is engaged with the protrusion 13e of the rotary plate 13, the forward and backward movable plate 15 is rotated by the guide bar 13d.
The tray 9 moves forward while being guided by the tray guide 8 or 8' of the case l.

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 comes into contact with the protruding piece 9e of the tray 9 and retreats against the spring force of the spring 10n', returning the arm 101! , is rotated against the coil spring 10m, and the footer arm 10 once contacts the hook 9g of the tray 9, rotates against the spring force of the coil spring 10m, and then engages with the hook 9g. (Figure 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. When the moving body 10j retreats, the footer arm 10k is engaged with the hook 9g of the tray 9, and the release bin 100 is brought into contact with the elastic engagement piece 9f of the tray 9, causing the tray guide 8 or 8 Since the engagement with the protrusion 8a at 15 and the moving body 10j return to their initial positions (FIGS. 10 and 12).

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 Arm 10I! , passes while rotating the regulating piece 15c.

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 lOa, 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 moving body 10j, the return arm 10ffi
comes into contact with the regulating piece 15c, but at this point, the regulating piece 15c cannot rotate forward, so the return arm 10! is rotated against the spring force of a winding spring of 10 m.

When the return arm 10β is rotated, the return arm 10f
Since ' is pulled by the protrusion 10 of the hook arm 10 that is engaged with the protrusion 101' of f, the hook arm 10 also rotates in the same direction as the return arm 10ρ against the spring force of the winding spring 10m. Therefore, the engagement between the hook arm 10 and the hook 9g of the tray 9 is released. When the hook 9g is disengaged from the footer arm 10, the tray 9 is moved to the shaft 1 which is biased by the spring 10n'.
When the disk player 11 or 11' is pushed to the end of the guide groove 111ka by 0n and the back-and-forth moving plate 15 and the movable body 10j move to the end, the power to the motor 10a is cut off and the movement is stopped in the same manner as described above. (Figures 11 and 13).

Then, when the movement is stopped, the motor 10a 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
o, the elastic locking piece 9f is separated from the guide groove 1 of the disc player 11 or 11'.
While being engaged with the hook l1lk4 formed in the shaft 11ka, the shaft Ion continues to push the tray 9 by the spring force of the spring 10n'. 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 8'.

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. In addition, the disc players 11, 11'
Since both have the same configuration, only the upper 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. Reference numeral 111f includes a known turntable 111d that clamps the disk D between a clamper to be described later, and a pickup 11ie that moves toward and away from the turntable 111d in the horizontal direction and reads information on the disk D. A fixed roller 111fs that comes into contact with the support shaft 111b and a movable roller 111f2 that comes into elastic contact with the support shaft 111b are attached to one end, and the support shaft 111c is attached to the other end of the pick-up base. Two fixed rollers 111 fs and 111 fa that come into contact with the roller 111 fs and a movable roller 111 fa that comes into elastic contact with the spring 111 fs are attached. Therefore, the pickup base 111f has the above-mentioned roller l1lft~
It is supported to be movable only vertically by l 11 fs.

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, and the front slide plate has one guide hole 111g1 in the shape of a substantially slanted figure. Further, two guide holes (not shown) similar to those described above are formed in the rear slide plate. Further, a rack 111g2 is formed on a part of the upper edge of the slide plate 111g, and gears 111hs fixed to both ends of a rotating shaft 111h rotated by a motor (not shown) are meshed with this rack 111g2. Therefore, when the motor rotates and the gear 111h1 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 1lli1 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.
j is arranged, and a tray moving frame 111k is movably guided by this. A spring 1llks is tensioned between the tray moving frame 111 and the box 111a, and the tray moving frame 111k is constantly moved as shown in FIGS. 18 and 19.
In the figure, the spring is biased toward the left. Further, on the front and rear lower surfaces of the tray moving frame 111, hanging pieces 111 that come into contact with a moving plate 1111, which will be described later, are formed with 2. Moving board 1
11 is attached to the slide plate 111g described above so as to be horizontally movable, and a spring 111/2t is stretched between the slide plate 111g and the movable plate 1111.
is always biased to the right by a spring. Thus, 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 tip of the moving plate 1111 comes into contact with the hanging piece 111 of the tray moving frame 111. 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 1llkz 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, since the outer peripheral edge of the tray 9 is no longer located within the movement range of the pickup 111e, the size of the tray 9 can be made 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.
4 is formed on a protrusion 111 that is engaged with the elastic engagement piece 9f of the tray 9 when the tray 9 transferred by is inserted. 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 ll1mx 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 in the direction of pushing out the tray 9. Further, one end of the tray moving frame 111k is inserted into the tray guide 111ka,
There is a spring 1ll between the other end and the tray moving frame 111.
An L-shaped pressing plate 111n with a tension plate 111n is attached to press the side surface of the protruding piece 9e of the tray 9 inserted into the tray guide 111ka, 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 retaining piece 9 of the tray 9 is inserted into the tray guide 5.
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
0, when the elastic engagement piece 9f and the protrusion 111 are no longer engaged, the rotating push-out plate 111mt acts to push out the tray 9. In addition, the rotating extrusion plate 111m
1 prevents the tray 9 from wobbling in the front-rear direction when it is secured.

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, information on the disc D held between the turntable 111d 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, and 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 cause center runout, making tracking difficult. Therefore, in this embodiment, when reading the upper disk, the disk shifter D is held between the turntable 111d and the center of the disk is aligned by the clamper 113.

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

113d is a hollow shaft with a spring locking collar 113d1 formed on the upper end, and a cut groove 113d on the opposing surfaces of the lower end.
2 is formed, and a pin fitting hole 113da is formed opposite to the cut groove 113d2 at a position shifted by 90 degrees. 113e is a cut groove 11 of the hollow shaft 113d in the upper part.
A flat plate part 113e1 to be inserted into 3d2 is formed, and a shaft rod whose lower part is formed into a round shaft 113e2,
A long hole 113ea is formed in the flat plate portion 113es. The hollow shaft 113d has a spring 11 inside.
3f is inserted into the pipe 113b from above together with the spring 113g in a stored state, and the shaft rod 11
3e is inserted into the pipe 113b from below, and
The flat plate portion 113e1 is fitted into the cut groove 113d2. In this state, the pin 113h is inserted through one of the elongated holes 113b1 formed on the opposite surfaces of the pipe 113b, and the elongated holes 1 of the hollow shaft 113da and the shaft rod 113e are inserted.
The pin 113h penetrates through the elongated hole 113bl of the pipe 113b through 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 113g with respect to the pipe 113b.

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 113i1, 113i is a mounting plate screwed to the lower surface of the shaft rod 113e, and 113m is the mounting plate 11.
32 through a hair ring 1131t so as to be rotatably attached to the position regulating plate for positioning the disk,
The outer peripheral portion 113mx is formed in a tapered shape so as to coincide with the center hole of the disk D. Furthermore, a shaft tube 113m2 into which a fixed central shaft 111d1 of the turntable 111d is inserted projects downward from the center of the position regulating plate 113m.

The turntable 111d has a built-in motor 111d2.
The turntable main body 111da is rotated by the rotation of the turntable main body 111da, and a position regulating plate 111ds which is biased upward by a spring 1lld4 is attached to the center portion of the turntable main body 111da.

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

Tray guide 1ll 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, thereby causing the turntable to move. 111d rises. When the turntable 111d is raised, the position regulating plate 111d5 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 the lower surface of the disc D toward the disc pressing plate 113 of the clamper 113a, so that the disc D is pushed up against the turntable main body 111da.
and the disk pressing plate 113. Therefore, in this state, the motor 111 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 111d 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.
2 and the position regulating plate 11 at the corresponding contact position.
Stop 1ds. However, the turntable body 11
Since it is further pushed up by 1 da, the disc D is raised by the turntable main body 111 da, and the hole of the disc D passes through the position regulating plate 111 ds and reaches the position regulating plate 11.
The disk D is inserted into the 3 m outer peripheral portion 113m1, and the disk D is positioned by the position regulating plate 113m. and,
At the time when the turntable 111d has finished rising, the turntable main body 111da is pressing and clamping the disk D toward the disk pressing plate 113k of the clamper 113, so by driving the motor 111d2 of the turntable 111d, the disk D rotates (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.
The hook arm lok is disengaged from the elastic retaining piece 9f, and the hook arm lok is engaged with the hook 9g of the tray 9. Then, the motor 10a is rotated in the reverse direction to pull out the tray 9 from the tray guide 8 or 8' and into the guide groove 15b, and the motor 10a is rotated in the reverse direction to remove the tray 9 from the tray guide 8 or 8'.
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 in playback, the tray is moved 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 tray guide l1lka 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 arranges a pair of left and right tray guides for storing trays in a 7-shape toward the tray transfer means, and sets the center of rotation of the tray transfer means inside the intersection of the V-shape. Since it is arranged so that the tray transfer means is brought closer to the tray guide side, the depth of the case can be narrowed, and therefore, the size of the entire apparatus can be reduced.
