DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small-diameter disk adapter for accommodating a plurality of standard-diameter disks and for accommodating a small-diameter disk in a disk magazine used for a disk changer.

[0002]

2. Description of the Related Art Various types of disk magazines have been proposed, for example, in Japanese Patent Application Laid-Open No. 2-87360, due to the spread of in-vehicle CD (compact disk) autochangers. In addition to a standard disk having a diameter of 12 cm, a disk having a small diameter of 8 cm is also available. FIG. 11 is a perspective view of a conventional magazine for a standard diameter disc, and FIG. 12 is a perspective view of the inside of the magazine. A plurality of (six in this example) disks (not shown) are stored in a resin case 51 of a magazine indicated by the reference numeral 50 as a whole. In the case 51, partition plates 53 are provided in the vertical direction. Spacers 53a are provided at the ends of the partition plates 53 so that the disk storage portions 24 are provided between the partition plates.
Is formed. Disks are stored one by one in the disk storage unit 24. A pair of left and right leaf springs 25 are housed in the case 51, and the leaf springs 25 have comb-shaped slits so as to function in correspondence with the respective disk housing portions 24. Furthermore, in the back of the case 51,
The number of disc ejection pieces 2 corresponding to each disc storage section 24
6 is supported on a shaft 27. On the other hand, the lower cover 22 has a guide groove 22a for inserting the magazine 50 into a predetermined position of the magazine insertion portion of the disc changer and a concave portion 2 for engaging with a lock pin (not shown) for locking.
2b is provided.

FIG. 13 is a view for explaining the operation of a disk changer using a magazine 50. The urging direction of the leaf spring 25 changes depending on the position of the disk 11. When the disc 11 is completely inserted into the magazine 50, the leaf spring 25 is urged in a direction to accommodate the disc 11, and when the disc 11 is ejected, the leaf spring 25 is urged in the ejection direction near its final stroke. When the magazine 50 is inserted into the disc changer and locked, the disc pull-out arm 60 faces the rear end of the disc ejection piece 26.
At the time of loading a disk, the disk ejection arm 26 moves in the direction b at the height of the disk, whereby the disk discharge piece 26 rotates in the direction c around the shaft 27.
As a result, the disk 11 moves in the direction e. At this time, the disk 11 is sandwiched between the rollers 61 rotating in the direction of discharging the magazine 50 from the magazine 50, and the disk 11 is loaded into a disk positioning mechanism (not shown). When the disc is ejected, the roller 6 rotates in the reverse direction to the above.
1, the disc 11 is inserted into the magazine 50, and is completely stored by the leaf spring 25.

Here, in order to use the small-diameter disk 10 with the magazine 50, it is necessary to use the small-diameter disk adapter 70 shown in FIG. 14, and a standard method as shown in FIG. Storage disks 24a and 24b for storing the large-diameter disk and the small-diameter disk, respectively.
There is a method of using a magazine 80 to be stored in a magazine.

[0005]

Since the conventional disc changer is constructed as described above, in order to play a small-diameter disc, it is necessary to insert a commercially available adapter into each magazine with the adapter attached to each disc. Or use a dedicated magazine. The above-mentioned method using the adapter tends to cause an uncertain mounting state, and as a result,
The disc changer becomes inoperable. When a dedicated magazine is used, the number of standard-diameter disks and small-diameter disks is limited, resulting in an increase in size.

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned problems, and has as its object to obtain an adapter to which a small-diameter disk can be applied using a standard-diameter disk magazine.

[0007]

DISCLOSURE OF THE INVENTION Disc according to the present invention
Adapter for the small diameter disc in changer magazine has a plurality of discs inserted and removed are freely located at any position between <br/> Gajin for retractable standard diameter disk, having a thickness equivalent to the standard size disc A case having a substantially U-shaped case and a small-diameter disk disposed in the case is provided.
When the case is pulled out, the case
It is configured to remain in the gin. Also,
The disc provided in the magazine for standard-diameter discs

It is provided with a spring that biases in the direction.

[0008]

In the present invention, in the state where the small-diameter disk is accommodated in the standard-diameter disk magazine together with the small-diameter disk adapter, the small-diameter disk is opposed to the biasing force of the spring by the disk ejection arm via the disk discharge piece. It is pushed out in the ejection direction and sent to the disc playing mechanism side. In addition, at the position where the small-diameter disk is stored in the adapter, the small-diameter disk is spring-biased in the direction in which the adapter is stored, so that stable positioning can be performed.

[0009]

An embodiment of the present invention will be described below with reference to the drawings. In each drawing, the same or corresponding parts as those in the conventional example are denoted by the same reference numerals. FIG. 1 is a plan view of a small-diameter disk adapter according to the present invention, wherein the adapter is generally denoted by 1, 2 is a substantially U-shaped resin case having the same thickness as a standard-diameter disk, and 3 is A link 5 housed within the thickness of the case 2 and rotating about the support shaft 4 is a contact piece attached to one end of the link 3 and having a thickness substantially equal to that of the case 2. As shown in FIG. 2, the link 3 has a wide edge 3a at which the opposite edge of the contact piece 5 contacts a disc pull-out arm 60 (see FIG. 10) described later. 3 and 4, the recess 5a of the contact piece 5 shown in FIGS. 3 and 4 is engaged with the projection 3b, and the projection 5b is engaged with the groove 3c. I have. In addition,
3d is a shaft hole of the support shaft 4. Numeral 6 denotes a plate-like spring bent in a substantially "L" shape whose biasing direction is changed depending on the position of the small-diameter disk 10 in order to ensure its operation when the small-diameter disk 10 is inserted into or ejected from the adapter 1. As shown in FIG. 5, one end of the spring 6 is press-fitted and fixed to the case 2, and the other end is a free end 6b which freely moves in a space 2a in which the case is hollowed out. The spring force of the spring 6 is smaller than the spring force of the leaf spring 25 of the magazine 50 described in the conventional example.

Reference numeral 7 denotes an outer portion of the case 2 for locking the adapter 1 at a fixed position by a leaf spring 25 when the adapter 1 is inserted into a magazine of a standard-diameter disk, and reference numeral 8 denotes prevention of rotation of the adapter 1 in the magazine. The positioning projections 9 provided on the case 2 are projections for discharging the adapter 1 by gripping the adapter 1 with a finger from the magazine.

FIG. 6 is a perspective view of a magazine 20 in which a conventional magazine for a standard-diameter disk is partially modified. FIG. 7 is a perspective view showing the inside of the magazine in which the magazine 20 is inverted and the bottom cover 22 is removed. . The magazine 20 is different from the conventional magazine shown in FIGS. 11 and 12 in that a side plate portion in which both end portions of the disc insertion opening are shortened so that the protrusions 9 are exposed to pull out the adapter 1 from the magazine. 21
a was formed. FIG. 8 is a perspective view showing a state in which one small-diameter disk adapter 1 is inserted into the standard-diameter disk magazine 20, and FIGS. 9A and 9B schematically show the entire disk changer 30 using the disk magazine. FIGS. 3A and 3B are a plan view and a side view, respectively, showing a case of a mechanism section 31 in which an insertion section 34 of the magazine 20 and a disc playing mechanism 32 are integrated in a case 33. Of course, the disk playing mechanism 32 may be independent.

Next, the operation when the small-diameter disk adapter 1 according to the present invention is used will be described with reference to FIG.
When the disk ejection arm 60 moves in the direction b, the disk discharge piece 26 is rotated in the direction c with the support shaft 27 as a fulcrum, and in conjunction with this, the link 3 rotates in the direction d with the support shaft 4 as a fulcrum. I do. This enables the small-diameter disc 10
Is pushed out by the link 3 and is discharged in the e direction against the spring force of the spring 6. At this time, since the rollers 61 are rotating in the direction in which the disk 10 is sent to the disk playing mechanism, the disk 10 is ejected from the magazine 20 and sent to the disk playing mechanism.

On the other hand, when the disk is stored, the small-diameter disk 10 is rotated by the roller 61 which rotates in the storage direction,
The disc is sent from the disc playing mechanism to the adapter 1, and near the final stroke, the magazine 20 is biased by the spring 6.
It is completely stored inside and the position is fixed.

By forming the positioning projection 8 of the adapter 1 with a member having a large coefficient of friction, such as rubber, when the disc ejecting piece 26 is pushed in the direction c by the disc pull-out arm 60, the projection 8 is placed in the magazine 20. To prevent the adapter 1 from coming out of the magazine 20 by frictional engagement. In addition, the adapter 1 becomes unnecessary, and the magazine 20
In order to remove the adapter from the adapter, it is sufficient to grasp the ejection projection 9 of the adapter 1 with a finger and pull it out.

[0015]

As described above, according to the present invention,
By using the small-diameter disk adapter, it is possible to use the small-diameter disk by using the conventional standard-diameter disk magazine and the disk pull-out mechanism as they are. In addition, since the small-diameter disk adapter is housed in the standard-diameter disk magazine, there is no need to mount the adapter on each disk, and it is possible to prevent equipment damage due to incomplete disk mounting. Can be reduced in size.
