Description

[Detailed Description of the Invention] The present invention relates to a disk magazine used in a disk changer device.

Conventionally, many disk changer devices have been found, such as those in which a disk storage section is previously provided within the disk changer main body, or those in which the disk storage section is removable as a magazine unit. The former method is effective when there are a large number of disks, such as for business use, but there are problems in terms of disk exchange operations, operability, and storage of disks.The latter method uses a magazine containing disks as a unit to change disks. Since it can be attached to a storage device, it is easy to operate and the disk can be replaced easily, and the magazine itself can be used as a storage case for the disks. However, in this type of disk changer device, when taking out a disk from the magazine attached to the main body, it is necessary to remove the lid of the magazine, hold the disk inside the magazine, and take it out of the magazine. As a result, the structure of the disk changer device tends to be extremely complicated, and if there is any looseness between the disk and the disk storage section, it may be difficult to remove the disk properly. Furthermore, when the disk magazine is removed from the disk changer body and used as a disk storage case, there is a risk of scratching the disk if there is any looseness in the disk inside the magazine.

The present invention was developed to eliminate such drawbacks, and includes a plurality of trays for placing disks that are rotatably arranged inside the magazine body, and the magazine is opened through an opening formed on the side of the magazine body. By rotating outward, the disk can be taken out to the outside of the magazine, and when taking out the disk from the magazine, the tray inside the magazine is used to simplify the mechanism on the disk changer body side. To provide a novel magazine device such as a disk changer, which is capable of preventing rattling by pressing the disk against the upper surface of the tray on which it is placed when the disk is housed in the magazine.

Hereinafter, one embodiment of the magazine device of the present invention shown in the drawings will be described in detail.

FIG. 1 shows the disk magazine of the present invention, in which trays TA to TE on which disks D are placed are arranged in a magazine body M in a vertically overlapping manner and rotatable about an axis M1. and
From the opening M5 formed from the side surface M2 of the magazine body M to the adjacent side surfaces M3 and M4,
Each of them can be independently rotated to the outside of the magazine main body M.

Since the trays TA to TE are all formed in the same shape, the tray TA will be explained with reference to FIGS. A hole TA1 is formed to allow movement of the disk D, and around it are arcuate protrusions TA2 and TA for regulating the placement position of the disk D.
3, TA4 and TA5 are formed. As shown in FIG. 2b, which shows the cross section taken along line X-X' in FIG. , there is a notch between the protrusions TA4 and TA5.
TA6 is formed. Further, a guide protrusion TA7 that engages with a tray guide M6 (described later) provided in the magazine main body M is formed on the outside of the protrusion TA4.

Further, a recess TA8 is formed on the side surface of the tray TA, and when the tray TA is stored in the magazine main body M, it engages with the engagement piece S1a of the leaf spring S1 attached to the side surface M4 of the magazine M. However, the stored state of the tray is maintained.

On the other hand, inside the main body of the magazine M, as shown in Fig. 2a, when each tray rotates, each guide protrusion
A tray guide M6 that engages with and guides TA7 to TE7 is provided, and as is clear from FIG. 2c showing the Y-Y' cross section in FIG. Tray TA~
Guide grooves M6a to M6e corresponding to the guide protrusions TA7 to TE7 of the TE are formed on the upper and lower sides, respectively, and when the tray is in the magazine M and when it enters and exits the magazine M, the guide grooves M6a to M6e are formed to guide each guide protrusion to guide the tray. In addition to positioning the tray, the tray is configured to rotate smoothly.

In addition, when trays TA to TE are stored in the magazine M, a leaf spring S2 is arranged in the magazine M facing the notch TA6, and the trays are stored in the magazine M.
When TA~TE is stored in magazine M,
The leaf spring S2 is pressed against the outer periphery of the disk D protruding from the notch TA6 of the trays TA to TE, and presses it in the direction of arrow A in the figure.
As shown in FIG. 2B, the protrusions TA2 and TA3 are pressed against the inclined surfaces of the protrusions TA2 and TA3, and are subjected to force in the direction shown by arrow B in the figure, that is, in the direction of being pressed against the tray surface. Therefore, when the tray is stored in the magazine M, the disk D is pressed against the tray surface and is positioned without wobbling, and when the disk D is stored in the magazine M and is carried around, it is also damaged. It is highly safe and can be used not only as a magazine for a disk changer device, but also as a disk case for storing disk D.

Further, a pin 46c is provided on the upper surface of the cam plate 64, which is always engaged in a cam groove 64b formed on the lower surface of a cam disk 64, which will be described later.

The stabilizer control mechanism 47 is provided on the chassis 1 below the tray pulled out from the magazine M, and raises the disk to the turntable 8 together with the disk lifting mechanism 14, and also raises the disk using the stabilizer 57. It is attached to the turntable 8 and is ready for playing.

FIG. 11 is a perspective view of the stabilizer control mechanism 47. On the chassis 1, there are protrusions 4 on both sides.
8a, 48a, 48b, 48b is attached to the support plate 48, and the projecting pieces 48a, 48a
In between, a lever 49 is rotatably disposed at one end by a shaft 50, and a lever 51 is disposed at one end by a shaft 52 in elongated holes 48c, 48c formed in the projecting pieces 48b, 48b. The levers 49 and 51 are attached so as to be rotatable and movable back and forth, and the intermediate points of the levers 49 and 51 are connected by a pin 53, thereby forming an X-shaped link mechanism. A support plate 5 is attached to the other end of these levers.
4 is installed.

Like the support plate 48, the support plate 54 has protrusions 54a, 54a on both sides, and protrusions 54b, 54b each having elongated holes 54c, 54c, and between the protrusions 54a, the lever The other end of the lever 49 is rotatably attached by a shaft 55, and the other end of the lever 49 is rotatably attached to the elongated holes 54c, 54c by a shaft 56 so that it can move back and forth. installed.

Further, both ends of the shaft 52 are connected to springs S4 and S4, respectively.
Since the support plate 54 is always biased upward as seen in FIGS. 4 to 6 by S5, the support plate 54 is always biased toward the chassis 1 side.

Note that the pin 53 connecting the levers 49 and 51
is extended to the right as viewed in FIGS. 4 to 6, and a roller 53a is attached to the extended portion.
Therefore, by moving the roller 53a up and down, the support plate 54 can be vertically moved up and down while remaining horizontal with respect to the chassis 1 via the X-link mechanism (FIGS. 10a and 10b).

Further, on the support plate 54, there are provided a stabilizer 57 for pressing the disk onto the turntable 8, and a disk pressing piece 58 for lifting the disk horizontally by pushing up the vicinity of the outer periphery of the disk together with the disk lifting lever 40. . This disk pressing piece 58 is also similar to the disk lifting lever.
It consists of a disk mounting surface 58a and a protrusion 58b,
It is attached via a leaf spring 60.

Further, a protruding piece 59 is provided on the back surface of the chassis 6 of the disc playing section 3 facing the disc pressing piece 58, and as will be described in detail later, the stabilizer support plate 54 is raised so that the stabilizer 57 can sandwich the disc. When it is mounted on the turntable 8, it comes into contact with the disc pressing piece 58 and pushes it down against the leaf spring 60, thereby separating it from the disc D.

Further, as shown in FIGS. 4 to 6, the support plate 48
In parallel with this, a stabilizer control lever 61 is slidably arranged through long holes 61a, 61b and pins 62a, 62b, and the roller 53a of the pin 53 and the roller 53a of the pin 53 are arranged on the side surface facing the support plate 48. A side plate 63 is integrally formed with an engaging slope 63a for engaging and moving the side plate up and down.

Therefore, the stabilizer control lever 61 is moved up and down in FIGS. 4 to 6, that is, in FIGS. 10a and 10b.
By sliding from side to side, the roller 53a can be moved up and down using the engagement slope 63a, and the stabilizer support plate 54 can be moved up and down.

On the other hand, as described above, the stabilizer control lever 61 is attached to the rotating lever 4 by holding the pin 61c on its top surface.
6, and is always connected to the disk lifting mechanism 14.
It is designed to work in conjunction with the The rotary lever 46 is connected to a rotary rod 3 which controls the rotation of the operating lever 19 by a cam disk 64 which will be described later.
It is configured to operate continuously with 4. The cam disk 64 is rotatably disposed on the chassis 1 with a shaft 64d, and has a cam groove 64a for controlling the rotating rod 34 on its upper surface and a cam groove for controlling the rotating lever 47 on its lower surface. 64b are formed respectively.

As is clear from FIG. 8, the cam groove 64a extends from the large diameter portion 641a to the small diameter portion 642a.
The rotating rod 34 is formed continuously from the pin 3 to the pin 3.
4a is in the large diameter part 641a, clockwise,
When it is in the small diameter portion 642a, it is in a position rotated counterclockwise.

As is clear from FIG. 8, the cam groove 64b is also
It is formed continuously from the large diameter portion 641b to the small diameter portion 642b, and the rotating lever 46 is connected to its pin 46.
When c is in the large diameter portion 641b, it is rotated clockwise, and when it is in the small diameter portion 642b, it is rotated counterclockwise.

The relative positional relationship between the two cam grooves is as shown in the figure, but from the point of view of timing, when the disk is mounted, the rotating rod 34 is first rotated by the cam groove 641a, and the tray is removed from the magazine M. After taking it out, the rotating lever 46 is rotated by the cam groove 641b, the sliding lever 44 and the stabilizer control lever 61 are operated, and the disc on the tray is mounted on the turntable 8.

Further, a gear 64c is formed on the outer periphery of the cam disk 64, and a motor 65 arranged at the lower right side in FIG. , the rotation is transmitted through gears 71 after it has been sufficiently decelerated.

The rotation angle of the cam disk 64 is determined by the potentiometer 7.
2, and since this means has been well known in the past, its explanation will be omitted.

The disk changer device of the present invention is constructed as described above, and its operation will be explained next.

3 and 4 both show the stopped state before operation, and in this state, by inserting the magazine M from the left in the figure in the direction of arrow C, the magazine shown by the dashed line in the figure can be inserted. It can be installed in the installation position.

In addition, in the above-mentioned stopped state, the rotating rod 34
The engagement pin 34a is inserted into the cam groove 64 of the cam disk 64.
The lever 20 is located at the large diameter portion 641a of FIG. Therefore, the Y-shaped actuating lever 1
9 is rotated clockwise around the shaft 23a, and its arms 19a and 19b are located adjacent to the tray in the magazine M through the side surface M3 of the magazine M and the opening M5 of M2, respectively. be.

Meanwhile, a control circuit (not shown) is operated to drive the motor 25 of the disk selection mechanism 13 to rotate the cam disk 21 and change the engagement position between the engagement pin 24a of the actuating plate 24 and the cam wall 21a. By this,
By moving the operating lever 19 up and down, it is possible to select a tray to be taken out of the magazine.

Further, the L-shaped rotary lever 46 has a pin 46c that is connected to the large diameter portion of the cam groove 64b of the cam disk 64.
41b, and is in the state of being rotated clockwise. Therefore, the stabilizer control mechanism 47
The stabilizer control lever 61 is in the upwardly slid position as seen in FIG. position, the stabilizer support plate 54 has springs S4,
It is lowered onto the chassis 1 by S5 and is located below any tray of the magazine M. Therefore, even if each tray of the magazine M is selected and taken out in this state, the rotational movement of the trays is not hindered.

On the other hand, when the rotating lever 46 is rotated clockwise, the sliding lever 44 of the disk lifting mechanism 14 is in a position where it is slid to the left as shown in FIGS. 4 and 9a. As is clear from FIG. 9a, the rotating plate 41 is in a clockwise rotated position, and the disk lifting lever 40 is spaced below any tray of the magazine M through its elongated hole 41a. It is in a state of letting go. Therefore, even if a tray is selected and rotated, there is no obstruction.

In the above-mentioned state, the magazine M is mounted in the magazine mounting section 2, and after the operating lever 19 is opposed to a desired tray in the magazine M, the motor 65 is driven by a control circuit (not shown), and the cam disk 64 is rotated. By rotating clockwise, the tray can be taken out from the magazine M, and the disk placed on the tray can be mounted on the turntable 8.

That is, when the cam disc 64 starts rotating counterclockwise, the engagement pin 34a of the rotation rod 34 and the engagement pin 46c of the rotation lever 46 are moved into the cam groove 64, respectively.
A, 64b starts moving from the large diameter portions 641a, 641b to the small diameter portions 642a, 642b. At this time, since the large diameter portion 641a of the cam groove 64a is formed shorter than the cam groove 64b, as shown in FIG. Move to and turn the rotation rod 3.
4 rotates counterclockwise around a shaft 35, and moves the operating lever 19 via the sliding lever 20 to the guide shaft 23.
Rotate counterclockwise around a.

When the actuating lever 19 rotates counterclockwise, its arm 19a presses the side of the opposing tray in the magazine M, so that the tray is aligned with the axis M.
The magazine M rotates counterclockwise around 1 and moves to the outside of the magazine M, and is brought above the stabilizer 57 while being guided by the tray guides 17 and 18. When the tray is completely transferred above the stabilizer, it is supported by the shaft M of the magazine M and the tray guide 18.

After the above-mentioned tray movement is completely completed, the cam plate 6
4 further continues to rotate counterclockwise, the engagement pin 34a of the rotating rod 34 advances inside the small diameter portion 642a of the cam groove 64a, and the rotating position of the rotating rod 34 is maintained, while the rotating Engagement pin 46c of lever 46
is from the large diameter portion 641b of the cam groove 64b to the small diameter portion 64.
2b, and the rotating lever 46 is moved to the shaft 47.
Rotate counterclockwise around the center.

By rotating the rotating lever 46, the sliding lever 44 of the disk lifting mechanism is slid to the right, and as shown in FIG.
Rotate the rotating plate 41 counterclockwise as shown in
The disk lifting lever 40 is connected to the guide shafts 39a, 39.
Move it upward along b.

The rotation of the rotation lever 46 simultaneously causes the stabilizer control lever 61 to slide downward in the figure, that is, to the left in FIG. 10a. As a result, the roller 53a of the X-link mechanism is moved upward by the engagement slope 63a of the control lever 61, and the stabilizer support plate 54 is eventually moved upward.

That is, the disk D on the tray is moved by the disk pressing portions 40c and 40d of the disk lifting lever 40.
Then, the disk is lifted up while being supported at three points by the disk pressing pieces 58 on the stabilizer support plate 54.

Note that when the disc D is attached to the turntable 8, the disc pressing parts 40c and 40d of the disc raising lever and the disc pressing piece 58 on the stabilizer support plate must be spaced apart from the disc D. As shown in FIG. 10b, the movement range of the disk raising lever 40 is determined so that it stops slightly before the disk D contacts the turntable, and thereafter the disk D is turned by the stabilizer 57. It is adapted to be crimped onto the table 8.

Further, since the disk pressing piece 58 on the stabilizer support plate 54 rises together with the stabilizer 57, it cannot be stopped in front of the turntable 8 like the disk lifting lever. Then, the stabilizer 57 is raised to the uppermost position by the protruding piece 59 on the lower surface of the chassis 6 of the disc playing section 3, and the disc D is pressed against the turntable 8 and comes into contact with the protruding ridge 58b of the disc pressing piece 58. is pushed down against the leaf spring 60 and separated from the disk D.

When the above-mentioned operation is completed and the disc D is completely mounted on the turntable 8 by the stabilizer 57, the engaging pins 34a and 46c of the rotating rod 34 and the rotating lever 46 are inserted into the cam groove 64a, respectively. , 64b, the rotation angle of the cam disk 64 is detected by the potentiometer 72, and the motor 65 is stopped.

The above describes the operation from taking out the disk D from the magazine to mounting it on the turntable 8. This state is shown in FIG.

Then, in the state shown in FIG. 6, by rotating the motor 4 of the disc performance section 3 and scanning the surface of the disc with the pickup 5, the performance state can be achieved.

Next, a case in which the disk D mounted on the turntable 8 and in a performance or performance preparation state is stored in the magazine M will be briefly described.

In this case, all you need to do is to perform the exact opposite operation to when loading the disk mentioned above.
Although a detailed explanation will be omitted, in FIG. 6, the motor 65 is reversely rotated by a control circuit not shown.
The cam disk 64 is rotated clockwise in the opposite direction to when the disk is attached.

As a result, the engaging pin 4 of the rotating lever 46 is first
6c moves from the small diameter portion 642b of the cam groove 64b to the large diameter portion 641b, thereby rotating the rotating lever 46.
rotates clockwise, and the stabilizer control lever 6
1 as seen in FIG. 6, that is, to the right as seen in FIG.
Bring it to the lower position in Figure 0 a.

At the same time, the sliding lever 44 of the disk lifting mechanism 14 is also slid to the left as seen in FIGS. 6 and 9b, and the rotating plate 41 is rotated clockwise, eventually moving the disk lifting lever 40 downward. Figure 9a
Bring it to the lower position shown in .

As a result, the disk D is separated from the turntable 8 and placed on the tray taken out from the magazine M again as shown in FIG.

When the cam disc 64 further continues to rotate clockwise, the rotating rod 34 rotates clockwise as the engaging pin 34a moves from the small diameter section 642a to the large diameter section 641a of the cam groove 64a. The operating lever 19 is rotated clockwise via the sliding lever 20, and its arm 19b presses the opposite side of the tray to rotate the tray clockwise into the magazine M. The state returns to the state shown in FIG.

As a result, the tray on which the disk D is placed is stored into the magazine M again.

Also at this time, the cam disc 64 stops when the potentiometer 32 detects that the engaging pins 34a, 46c have rotated until they reach the starting ends of the cam grooves 64a, 64b, as described above.

As described above, according to the disk magazine of the present invention, a plurality of trays for placing disks are rotatably disposed inside the magazine body, and the trays are arranged so as to be rotatable inside the magazine body, and the trays are arranged so as to be able to move outward from the magazine through the opening formed on the side surface of the magazine body. By rotating the disk to the outside of the magazine, the disk can be taken out of the magazine.When taking out a disk from the magazine, all that is required is to rotate the tray inside the magazine. There is no need to provide a mechanism for holding the disk in the magazine and taking it out from the magazine, and only a mechanism for rotating the tray is required, so the mechanism of the disk changer body can be greatly simplified, and When the tray is stored in the magazine body, the disk is pressed onto the tray to prevent it from rattling, so there is no risk of the disc rattling inside the magazine and causing damage to the magazine. Even when the disk is removed from the disk changer and used as a disk storage case, the effect is great as it protects the disk from scratches, etc.

Incidentally, in the above embodiment, the case was described in which the number of trays in the disk magazine was five, but the number of trays in the magazine may be changed as necessary. However, in that case, it is necessary to simultaneously reset the number of stages of the cam wall 21a of the cam disk 21 and the rotation angle of the cam disk 21 so that the operating lever 19 can be moved to a position facing each tray.
