Abstract

PURPOSE:To avoid the soil and wear of the information recording surface of a hard disk by forming a spindle inserting hole to a disk store case and at the same time a supporting part for an area of the disk excepting the information recording surface. CONSTITUTION:The inside space between a case main body 4 and a cover 6 is narrowed at the outer circumference part of a disk 2, and this outer circumferential part is held lightly at the inner side of the case. The space between the disk 2 and the inner side of the case increases at the inner circumferential part of the disk 2. Therefore the information recording surface of the disk 2 has no contact with the main body 4 nor the cover 6. A spindle 5 which is positioned vertically on the basis of a reference surface 7 is loaded to a disk 2 through a spindle inserting hole 8. Under such conditions, the spindle 5 is rotated to give rotation to the disk 2 without having a contact between the informaton recording surface of the disk 2 and both main body 4 and cover 6 respectively.

Description

[Detailed Description of the Invention] [Field of Application] The present invention relates to a disc storage case for recording and reproducing information with a hard disc such as a compact disc stored therein. The present invention relates to a disc storage case suitable for recording or reproducing information by rotating the information recording surface and the inner surface of the disc storage case without contact.

[Background of the invention]

A conventional compact optical disk storage case will be described below with reference to the drawings.

FIG. 1 shows a perspective view of a conventional disc storage case and a procedure diagram for mounting a disc from the disc storage case onto a spindle of a player.

The case body 4 having a lid 6 has a projection formed on the central part of the inner surface with a larger diameter around the spindle hole 3 of the disk 2, and a projection with a smaller diameter around the spindle hole 3 formed on the projection. 1 protrusion is formed. The first protrusion 1 is inserted into the spindle hole 3 of the disk 2 and supports the disk 2 so that the information recording surface of the disk 2 does not come into contact with the inner surface of the case body 4.

When attaching disk 2 to spindle 5 of the player,
First, the lid 6 is opened and the disc 2 is taken out by hand. Next, the disc 2 is carried to the spindle 5 of the player and mounted on the spindle 5.

As mentioned above, in conventional compact optical disc storage cases, when installing a compact 3 optical disc into a player, it is necessary to hold the disc 2 directly, resulting in fingerprints etc. on the information recording surface and deteriorating the sound quality. The disadvantage was that there was a risk of

Furthermore, compact floppy disks and the like are housed in a case called a cartridge. In compact floppy disks, etc., the information recording surface comes into contact with the inner surface of the cartridge when the disk is stored in the case and during recording/playback, causing wear and tear on the information recording surface. There were drawbacks such as the risk of sticking.

〔the purpose〕

The present invention has been made to eliminate the above-mentioned drawbacks, and its purpose is to prevent hard disks such as compact disks from staining the information recording surface of the hard disk,
To provide a disc storage case suitable for use in vehicles, autochangers, and general household player devices, which allows recording, reproduction, and storage without causing wear or damage to the recording surface.

〔overview〕

In order to achieve the above object, the present invention provides a disk storage case for a disk, particularly a hard disk such as a compact disk, wherein the disk storage case is provided with a spindle insertion hole, and the inner surface of the disk storage case is provided with a spindle insertion hole. The feature is that a support portion is formed to support a portion other than the information recording surface.

〔Example〕

The present invention will be described in detail below with reference to the drawings.

FIG. 2 is a perspective view of the first embodiment of the present invention, and FIG. 3 is a perspective view of the second embodiment.
A sectional view taken along a line perpendicular to the pivot axis of the lid 6 shown and passing through the center of the spindle hole 3 of the disk 2.

In FIGS. 2 and 3, the same reference numerals as in FIG. 1 refer to the same or equivalent parts.

In FIGS. 2 and 3, the inner surfaces of the case body 4 and its lid 6 are formed in a concave shape. For this reason, the case body 4 and the lid 6
The internal space between the discs 2 becomes narrower at the outer periphery of the disc 2, and the outer periphery of the disc is lightly supported by the inner surface of the disc storage case. Conversely, at the inner circumference, the distance between the inner surface of the disk storage case and the disk 2 increases. Therefore, the information recording surface of the disc 2 does not come into contact with the case body 4 and the lid 6. A spindle insertion hole 8 for inserting a spindle is provided in the center of the case body 4, and a clamper insertion hole 9 for inserting a clamper is provided in the center of the lid 6.

Reference numeral 12 in FIG. 2 is a window for a pickup device formed in the case body 4. This is a window when the information recording surface is on one side of the disc 2. If the information recording surface is on both sides, it goes without saying that the pickup device window is provided not only in the case body 4 but also in the lid 6.

FIG. 4 shows a sectional view similar to FIG. 3 when the disc storage case of FIG. 2 is attached to the spindle of a player.

In FIG. 4, the same reference numerals as in FIGS. 1 to 3 refer to the same or similar parts.

The case body 4 is fixed on a reference surface 7, and a spindle A15 whose upper and lower sides W are determined with reference to the reference surface 7 is attached to the disk 2 through the spindle insertion hole 8t. In some cases, the clamper is inserted into the clamper insertion hole 9f and onto the spindle 5 to ensure attachment of the spindle 5 to the disk 2. By rotating the spindle 5 in this state, the information recording surface of the disc 2 is transferred to the case body 4.
And the disk 2 can be rotated without contacting the lid 6.

By providing an appropriate gap between the outer periphery of the disk and the case body 4 and lid 6, it is possible to reduce the friction between the outer periphery of the disk and the case body 4 and the lid 6 during rotation, and also to reduce noise. It also reduces the burden on the case.

FIG. 5 is a sectional view similar to FIG. 3 of a disk storage case showing a modification of the first embodiment.

In FIG. 5, the same reference numerals as in FIGS. 1 to 4 refer to the same or equivalent parts.

The disc storage case shown in Fig. 5 consists of a case body 4 and a lid 6.
The inner surface of the case body 4 and the lid 6 have linear inclined surfaces near their outer peripheries, unlike the concave shape that draws a gentle arc as shown in FIG. The effects of this disk storage case are similar to those of the first embodiment of the present invention described in FIG.

FIG. 6 is a sectional view similar to FIG. 3 of the second embodiment of the present invention.

In FIG. 6, the same reference numerals as in FIGS. 1 to 5 refer to the same or equivalent parts.

The disc storage case according to this embodiment has a second annular ring located inside the case body 4 and the lid 6 and near the spindle hole 3. A sixth projection 10.11 is provided. This second
．． The third protrusion 10.11 corresponds to the non-recorded part of the inner circumference of the disc 2 and supports the skeleton disc 2.

According to the disk storage case, when the disk 2 is stored, unlike the first embodiment, the disk 2 is not supported by its outer circumference, but by the non-information-recorded portion near the spindle hole 3.

On the other hand, when recording or reproducing the disc 2, the spindle 5 is inserted into the disc 2 through the spindle insertion hole 8, as shown in FIG. The use of the clamper is the same as in the first embodiment of the present invention.

In this embodiment, when the disk 2 rotates, the second.
The relative speed between the fifth projection 10.11 and the disk 2 is the same as that of the second projection 10.11. Since the third protrusion is located on the center side of the disk 2, it is slow and the noise is lower than in the case of FIGS. 3 and 5.
Also, wear is reduced.

In addition, in this example, the second. Third protrusion 10-1
Although the case body 4 and the lid 6 each have an annular shape, the present embodiment is not limited to this, and an elliptic annular shape may be used, or two or more protrusions may be provided on each of the case body 4 and the lid 6.

〔effect〕

As is clear from the above description, the following effects are achieved according to the present invention.

(1) Since the disc can be mounted on the spindle of the player while being stored in the disc storage case, the information recording surface of the disc will not be contaminated.

Therefore, there is no risk that noise will be mixed into the recorded or reproduced information and the sound quality will deteriorate.

(2) Since the disk can be rotated without contact between the information recording surface of the disk and the inner surface of the disk storage case, the information recording surface of the disk will not be worn out or scratched. There's nothing to do.

(3) The information recording surface can be sufficiently preserved regardless of whether the disc is being stored or recorded or reproduced.
