Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a disk changer device, and in particular, it is equipped with a plurality of trays on which disks are placed, and these trays are used to transfer disks from magazines to disks. This invention aims to improve the disk changing operation in a disk changer device using a disk magazine that is transported to a performance section or vice versa.

[Conventional technology and its problems]

Various types of disk changer devices have been considered in the past, but they can be roughly divided into those that do not have a magazine and have a disk storage section pre-formed inside the disk changer device, and those that do not have a magazine. There is a magazine unit which can be attached to and detached from a disk changer device (for example, Utility Model Application No. 173,754/1989, previously filed by the present applicant).

The former is effective when there are a large number of disks, such as for business use, and it is difficult to attach and detach magazines. May be unsuitable for use.

On the other hand, with the latter, a magazine containing multiple disks can be attached to and removed from the disk changer device unit by unit at once, making it easy to operate, and since the magazine itself serves as a disk storage case, It is also effective in terms of protection and has more effects than the former.

However, since the disks are attached and detached in magazine unit units, once the magazine is attached to the disk changer device, if a disk needs to be replaced, it is possible to replace one of the multiple disks. However, the magazine must be removed from the disk changer device again and the disk inside must be replaced, making it impossible to take full advantage of the ability to attach and detach the magazine itself on a magazine unit basis. It had the following drawbacks.

[Purpose of invention]

As described above, the present invention is a disk changer device in which a plurality of disks can be attached and detached in magazine unit units, and the disks in the magazine can be attached and detached even when a magazine is attached to the disk changer device. The purpose is to do so.

[Summary of the idea]

A plurality of trays on which disks can be placed are rotatably arranged around the same axis within the magazine body, and the disks are taken out by rotating these trays to the outside of the magazine. The disc is played from within the magazine by rotating the tray between a first position housed in the magazine body and a second position facing the disc playing section. In a disk changer device adapted to transfer the tray to a station or vice versa, the tray is stopped at a third position between the first position and the second position, and the tray is stopped at a third position between the first and second positions; By forming an opening for disk exchange on the side of the disk changer device body opposite to the position, the disk on the tray brought to the third position can be loaded and removed from the opening for disk exchange. A new disk changer device constructed.

〔Example〕

Figures 11 and 12a show an example of a disk magazine used in the disk changer device of the present invention, in which trays TA to TE on which disks D are placed are stacked vertically on the main body of the magazine M. In addition, they are arranged to be rotatable around the axis M1, and each independently rotates outward from the magazine M body through an opening M5 formed from the side surface M2 of the magazine body to the adjacent side surfaces M3 and M4. It is becoming possible to do so.

Trays TA to TE all have the same shape, so to explain tray TC, a disk mounting surface TC1 is formed on the top surface of the tray, and a disk mounting surface TC1 is formed in the center of the tray, and a disk on the tray is mounted on the turntable described later. A hole TC2 is formed through which a stabilizer is inserted. Projections TC3, TC4, and TC5 for regulating the mounting position of the disk D are formed around the disk mounting surface, respectively.

As is clear from FIG. 12b showing the X-X' cross section, the protrusions TC3 and TC4 each extend from the disk mounting surface TC1 to the thickness of the disk D on the surface facing the disk D. Inclined surfaces TC31, TC32, TC41, and TC42 are formed on the top and bottom, and the disk placed on the disk mounting surface TC1 is pressed onto the protrusions TC3 and TC4 (arrow A
direction), the inclined surfaces TC31 and TC41 apply a pressing force to the disk mounting surface TC1 (in the direction of arrow B). Also a protrusion
Since the upper portions of TC3 and TC4 are inclined outward (slanted surfaces TC32 and TC42), when placing a disk on the tray, it is possible to guide the disk onto the disk mounting surface TC1 without getting caught. In addition, as will be described later, if two disks are mistakenly placed, the upper disk will be pulled away above the disk mounting surface.

In addition, on the outside of the protrusion TC5 and on the side of the tray TC,
Tray guide M6 provided inside the magazine M body
Engagement portions TC6 and TC8 are formed to engage with each other (described later), and a window formed on the side surface of the magazine M body is formed on the side surface of the engagement portion TC6 when the tray is stored in the magazine M. Color TC7 is applied so that it can be visually seen from M9 (see Fig. 12g), and it is possible to know which tray has been taken out even from outside the magazine M.

The engaging portion TC8 includes a lock lever L, which will be described later.
Notches TC9 and TC10 that engage with the leaf spring S1, and a finger rest TC for manually operating the tray TC.
11 are formed respectively.

Also, as is clear from FIG. 12c showing the Z-Z' cross section in FIG. On the bottom side, disk 2
A protrusion TC12 for preventing sheet insertion is formed, and a tray TC
In order to escape the protrusion TB12 on the lower surface of the upper tray TB, an arcuate groove TC13 is formed along the locus of movement of the protrusion when the tray is rotated.

Therefore, the tray below tray TC
On the top surface of the TD, there is a protrusion TC12 on the bottom surface of the tray TC.
An arcuate groove TD13 is formed to allow movement of. All other trays have the same configuration. In addition, a tray is provided on the bottom surface of the upper plate of the magazine M.
A protrusion M10 is formed to prevent two disks from being inserted into the TA. Note that since no tray exists below the tray TE, no protrusion is required on the lower surface of the tray TE.

Furthermore, as can be seen with reference to FIGS. 13a and 13b, the gap between the disk mounting surface of each tray and the lower surface of the upper tray or the projection on the lower surface of the upper plate of the magazine M is at least the width of one disk. The thickness is set to be greater than or equal to the thickness of two disks. As will be explained later, if two disks are placed on top of each other by mistake, only the lower disk on the disk mounting surface will be stored in the magazine, and the upper disk will not be stored in the magazine M. This is to ensure that.

On the other hand, when looking inside the main body of the magazine M, when each tray rotates, its respective engaging parts TA6 to TE6 and TA
A tray guide M6 that engages with and guides TE8 to TE8 is provided.
6, as is clear from FIG. 12 d showing the W-W' cross section in FIG.
~Each engaging part of TE TA6~TE6 and TA8~TE8
Guide grooves M6a to M6e corresponding to the trays are formed on the top and bottom, respectively, and when the tray is in the magazine M and when moving in and out of the magazine M, guide grooves TA6 to TE6 and TA8 to TE8 are guided to guide the tray. In addition to positioning the tray, the tray is configured to rotate smoothly.

Inside the tray guide M6, a lock lever L for maintaining the storage state of each tray in the main body of the magazine M is disposed so as to be rotatable about a shaft M7 on the side of the magazine M, as shown in FIG. 12e. , each guide groove M6a~ of the tray guide M6 is provided at one end
Lock claws La~ protrude into each guide groove from holes formed in M6e and engage and lock cutouts TA9~TE9 of each tray TA~TE.
Le is formed, and the other end has a magazine M.
A lock release button Lf is formed which is exposed to the outside of the magazine through the hole M8 on the side surface. By pressing this button from the outside of the magazine M, the lock lever L is rotated clockwise, and each tray is locked. It is now possible to release the

Further, a leaf spring S1 is disposed above the lock lever L as seen in the figure, and as will be clear with reference to FIG.
A pressing piece S1f is formed that presses against the back side of the tray and rotates it counterclockwise, and the other end projects into the guide grooves M6a to M6e of the tray guide M6 to form a notch in each of the trays TA to TE. TA10～TE1
engaging pieces S1a to S1 for click-stopping the storage position of each tray;
e is formed.

Therefore, when each tray is stored in the magazine M, the engaging pieces S1a to S1 of the spring S1
e engages with the notches TA10 to TE10 of each tray, and the lock claws La to TE of the lock lever L engage.
By engaging Le with the notches TA9 to TE9 of each tray, each storage state can be maintained.

That is, even if the push button Lf is pressed to release the lock of each tray, each tray is individually locked by the engaging pieces S1a to S1e of the spring S1, so any one of the trays is locked in the magazine M. When you take out the magazine M, the other trays will not move inadvertently, and you can always take out only the tray that should be taken out to the outside of the magazine M. Furthermore, when replacing the disk of the magazine M, etc., you can press the button. Even if the lock is released by pressing Lf, the trays do not move outside the magazine M all at once, which is effective in preventing the disks from falling.

In addition, in FIG. 12a, a leaf spring S2 is attached to the inner surface facing the opening M5 in the magazine M, and when viewed from the tray TD, when the tray is stored in the magazine M, the tray TD The protrusion TD3 is pressed against the side surface of the upper disk D.
TD4 (in the direction of arrow A in FIG. 12b), and the disk D can be pressed by the inclined surface TD31 against the disk mounting surface TD1 of the tray TD (in the direction of arrow B in FIG. 12b). .

Therefore, when the tray is stored in the magazine M, the disk D is pressed onto the tray, so that the disk can be protected from scratches due to rattling, misalignment, etc. It can be used not only as a magazine for a disk changer device, but also as a case for storing and storing disks.

In addition, the disk changer device of the present invention has the following features:
A mechanism for preventing two disks from being placed on the tray is provided, and its operation will be explained next.

When one disk is placed on each tray, Y-
As can be seen from FIG. 13a showing the Y' cross section, the disk is housed within the disk mounting surface and does not protrude above the tray, for example, the tray TC.
When it is rotated (in the direction of arrow C) into the magazine M, it can be stored into the magazine M without coming into contact with the protrusion TB12 on the lower surface of the upper tray TB.

On the other hand, when two disks are stacked on the tray, as is clear from FIG. 13b, the lower disk is accommodated within the disk mounting surface TC1, but the upper disk is It is positioned opposite to the protrusion TB12 on the lower surface of the upper tray TB.

Therefore, a tray with two disks placed on it
When the TC is rotated into the magazine M, the upper disk comes into contact with the protrusion TB12 on the lower surface of the upper tray TB stored in the magazine M and is locked.
The upper disk is not stored inside the magazine.

In addition, the protrusions TC3 and TC4 on the tray have sloped surfaces TC31 and TC41 facing the upper disk, so the upper disk is on the upper tray.
By rotating the tray further into the magazine M from the state where it is in contact with the protrusion TB12 on the lower surface of the TB, the upper disk rides on the protrusions TC3 and TC4 (in the direction of arrow C') and can be easily removed. . As a result, even if two small and thin disks are mistakenly placed on the tray, the magazine M
This can be removed at the stage of storing the tray in the magazine, and the disks are always correctly loaded one by one on the tray in the magazine.

Therefore, the height of the operating lever 29 can be varied, and the tray to be taken out can be selected from TA to TE.

After the tray selection operation is completed, the tray loading operation is started by closing the switch SW _2. However, when the tray is stopped at a position facing the disk exchange opening 3 shown in Fig. 1, the switch SW 2 is closed.
Before operating SW ₂ , close switch SW ₈ and set flip-flop FF4.

By closing switch SW ₂ , which starts the loading operation of the tray, the AND circuit AND
All input terminals of flip-flop FF1 become high level, and its output terminal becomes high level, and flip-flop FF1 becomes high level.
is set, and both the input terminals of the AND circuit AND2 become high level, so that its output terminal, that is, the input terminal MT1 of the motor control amplifier MT
becomes a high level and the motor 40 operates the operating lever 29.
Start rotating counterclockwise.

As a result, the tray facing the arm 29a of the actuating lever 29 is pressed against its side surface, rotates counterclockwise to the outside of the magazine around the axis M1, and turns while being guided by the tray guides 22 and 23. Move to a position facing the table 13. Further, as the operating lever 29 rotates, the operating piece 34a of the gear 34 leaves the switch SW ₃ , as shown in FIG. 6, and the switch SW ₃ is opened.

While the tray is moving, switches SW ₁₀ , which are arranged on the tray guides 22 and 23 as shown in FIG.
Press SW ₁₁ to close it, and the AND circuit
Both input terminals of AND5 become high level, and its output terminal becomes high level. At this time, if flip-flop FF4 has been set by closing switch _SW8 in advance, the NAND circuit
Both input terminals of NAND become high level, its output terminal becomes low level, and then the AND circuit
AND2 output terminal or motor control amplifier
The input terminal MT1 of the MT becomes a low level, and the motor 40 stops when the operating lever 29 is rotated to the position shown in FIG. Therefore, the operator can load and unload the disk onto the tray through the disk exchange opening 3.

After replacing the disk, etc., close the switch _SW9 to reset the flip-flop FF4, and the output terminal of the NAND circuit NAND, that is, the input terminal MT1 of the motor control amplifier MT becomes high level again. , the motor 40 starts rotating in the same direction as before stopping. As a result, the operating lever 29 also starts rotating counterclockwise, moving the tray to a position facing the turntable 13.

Incidentally, when the tray is brought to the disk exchange position shown in FIG. 1 and switches SW ₁₀ and SW ₁₁ are closed, the flip-flop is opened by switch SW ₈ .
If FF4 is not set, NAND circuit
The NAND output terminal remains at high level and does not change.
Since the output terminal of the AND circuit AND2, that is, the input terminal MT1 of the motor control amplifier MT does not change, the motor 40 continues to rotate, and the operating lever 29 moves the tray to a position facing the turntable 13 without stopping.

When the operating lever 29 continues to rotate and the tray is brought to a position facing the turntable 13 and the stabilizer 52 as shown in FIG _. It is closed and flip-flop FF1 is reset.
As a result, the output terminal of the AND circuit AND2, that is, the input terminal MT1 of the motor control amplifier MT becomes low level, and the motor 40 stops.

Also, by closing switch _SW4 , the set terminal of flip-flop FF3 becomes high level and is set, and the input terminal MS1 of motor control amplifier MS is set.
becomes a high level, and the motor 62 starts rotating the cam disk 60 in a clockwise direction.

When the cam disk 60 rotates clockwise, the pin 59b of the rotating lever 59 moves in the cam groove 601 toward the large diameter portion 601a, thereby rotating the rotating lever 59 clockwise and moving the sliding plate 57 as shown in FIG. It slides upward as seen in Figure 7a, that is, to the right as seen in Figure 7a. Therefore, the engagement rollers 45i and 51a of the disk lift lever 45 and the stabilizer 52 are connected to the engagement slope 571, respectively.

It will be raised to 13. And the disk lift lever 45 is the turntable 13
It stops slightly before the turntable 13, and is then attached to the turntable 13 by the stabilizer 52. At this time, the disk pressing piece 54 comes into contact with the protruding piece 56 on the lower surface of the sub-chassis 12, is pushed down, and is separated from the disk D. That is, when the disc D is mounted on the turntable 13, the disc lifting lever 45 and the disc pressing piece 54 are both spaced apart from the disc so as not to interfere with the rotation of the disc.

The above state is shown in FIG. 7b.

On the other hand, in the above-mentioned state, the pin 59b of the rotating lever 59 is attached to the large diameter portion 601a of the cam groove 601.
The switch _SW5 is closed by the front end of the sliding plate 57, and the flip-flop FF3 is closed.

1 becomes a low level, the motor 62 stops, and the cam disk 60 also stops. Further, SW ₇ is opened by separating the sliding plate 57.

The above is the operation until the tray-shaped disk in the magazine M is mounted on the turntable 13.
After the disc is mounted on the turntable 13, the motor 10 and pickup 11 can be driven by a control means (not shown) to play the disc.

Next, the operation of storing the disk D mounted on the turntable 13 into the magazine together with the tray (unloading operation) will be described.

In this state, switches SW ₁ , SW ₄ , and SW ₅ are closed, and switches SW ₃ and SW ₇ are open, and the unloading operation is started by closing switch SW ₆ . Even during operation, the tray can be stopped at a position facing the disk exchange opening 3. In this case, switch _SW8 is closed in advance to set flip-flop FF4.

By pressing switch SW ₆ to close it,
