JPS6224490A - Storage case for recording disc - Google Patents

Abstract

PURPOSE:To reduce a preservation space and use a recording disc stored in a case as it is by adopting the case thickness variable system and using a center holder as a closing member of an aperture part like a center hole. CONSTITUTION:A box-shaped upper face 2 where a center hole 1 is formed and a lower case 4 having a center hole 3 are fitted to each other without space, and an upper center holder 8 having a guide hole part 7 and a lower center holder 12 having a disc guide part 11 which supports the center of a recording disc 10 are pressed to upper and lower cases 2 and 4 by a compression spring 9 so that dust does not penetrate them. When the storage case is set to a playing mechanism, a boss 17 is depressed by an arm 20 and the upper case 2 is pushed by a holding part 21 and the lower case 4 is separated from the upper case 2. A clamper 19 pushes an upper center holder 8, and the recording disc 10 and the lower center holder 12 are pushed to hold a turntable 18, and the recording disc 10 is rotatable.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a storage case for recording discs, and particularly relates to a storage case suitable for improving dustproofing and storage space. [Background of the Invention] As described in Japanese Patent Application Laid-Open No. 55-14562, the case of the recording disk is pressed against the recording disk and pulled apart during use to prevent dust from entering through the center hole.

However, when the strength of the recording disk case is high, the force increases and the gap cannot be kept large, making it unsuitable for objects with large vibrations, and no consideration is given to reducing the storage space. ◇ [Object of the Invention] The object of the present invention is to provide a storage case for recording discs that requires a small storage space and can be used while being stored in the case to prevent dust, dirt, etc. from adhering to the recording discs. It's about doing.

[Summary of the invention]

According to one embodiment of the present invention, in order to reduce the storage space, the thickness of the case is variable, and the center hole and other openings are shielded to prevent dust 9 from entering, and when in use, the recording disk rotates. The case is expanded as much as possible, the aperture shielding member is separated from the case, and the shielding member is used as a center holder.

[Embodiments of the invention]

An embodiment of the present invention will be explained below with reference to FIGS. 1, 2, and 3. A projection 5 formed on a box-shaped upper case 2 having a center hole 1 and a lower case 4 having a center hole 3 and fitted into the upper case 2 with almost no gap. They are attached so that they are pulled together by springs attached to the upper case.

Also, an upper center holder 8 having a guide hole 7 and a lower center holder having a disk guide 11 that fits into the guide hole 7 and supports the center of the recording disk 10 with a compression spring 9 interposed therebetween. 12 is inserted and pressed against the upper case 2 and lower case 4 by the compression spring 9. Furthermore, the lower case 4 forms a reading hole 16 and is not attached to the shutter 14 with a fulcrum 15 and a spring 16 so as to cover it, and a boss 17 that passes through the upper case 2.
is the provision. In Fig. 3, 18 is a turntable that rotates the recording disk 10゛ and a clamper 1 installed on the upper side.
an arm 2o that presses down the upper center holder 8;
The zero-order operation, which is configured to be played by a playing mechanism consisting of a holding portion 21 supporting the upper case 2, will be described.

When this storage case is not in use, it is as shown in FIG. 2, with the upper center holder 8 and lower center holder 12 pressed against the upper and lower cases 2.4 to prevent dust from entering. Also, the upper and lower cases are closer and thinner. When in use (when installed in the performance mechanism as shown in Figure 3), arm 2
Since the boss 17 is pushed downward by the angle, the lower case 4 and the upper case 2 are pushed toward the holding part 21, and the lower case 4 is further moved 141ffi from the upper case 2.

Since the clamper 19 still pushes the upper center holder 8,
A recording disk 10 and a lower center holder 12 are held on a push turn table 18. At this time, the upper center holder 8, the lower center holder 12, and the recording disk 10 are separated from the upper case 2 and the lower case 4, and a sufficient space is provided around them, allowing rotation. At this time, the shutter 14 is opened to open the reading hole 13. (The opening/closing method is possible by the surrounding mechanisms regardless of the invention, so illustrations and explanations are omitted.) According to this embodiment, the arm can hold the lower case and the clamper at the same time, simplifying the playing mechanism. [Effects of the Invention] According to the present invention, it is possible to play the recording disc without taking it out of the storage case, and when it is still inconvenient, the upper and lower cases become thinner. This has the effect of not taking up much storage space, and since the center holder serves as a dust-proofing function, the dust-proofing effect and structural simplification can be achieved, and the economical effect is also great.
