Abstract

PROBLEM TO BE SOLVED: To simplify a CD case, save natural resources, reduce a manufacturing cost and expand a scope of its utilization. SOLUTION: A single plate is formed with a notch fitting part coincided with an outer shape of a CD, its central part is provided with a mounting table and a hollow columnar engagement segment and an extremity end of the columnar engagement segment is formed in a P-shape to prevent the CD from being disengaged. An end part of a base plate is formed with a string passing-hole to facilitate its arrangement and storage.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case of a storage medium required for utilizing a computer.

[0002]

2. Description of the Related Art A CD case is generally larger than the diameter of a CD. For a CD having a thickness of 1 mm, the case is generally a 10 mm thick upper and lower box made of resin. In addition, there is an object which adds a mounting plate to prevent scratches and dirt, and is excessively protected, so that plastic resources are excessively used, and the volume is large, which is very inconvenient for holding and storing. In particular, the heavy use of non-combustible resources sometimes leads to the production of a huge amount of waste products, which poses a challenge that cannot be left untreated due to future environmental problems.

[0003]

The prior art has the following disadvantages. (B) The concept of delicate, sensitive, and expensive CD cases that began during the CD creation era and that was designed based on strict protection is still being maintained. . (B) Due to valuable thinking and added value of products, the volume form becomes excessive due to excessive use of resin resources, which is bulky and inconvenient to carry or store, and requires simplification and resource saving. (C) Due to technological advances and manufacturing process reforms, CD prices are competing for low prices, and in cases, progress and innovation are late and high, and CDs are cheap. (D) CDs and DVDs are considered to have a circular shape, but in recent years, a card type or the like has been created and reform has begun. The present invention has been made to eliminate these inconveniences.

[0004]

The medium 1 is fitted by providing a concave fitting portion 2 corresponding to the outer shape of the medium 1. Since the center hole of the other medium is invariable, a medium other than a circle can be handled. The medium 1 has a magnetic storage device on one side and a non-magnetic material on the opposite side, which is used for displaying normal contents. That is, it can be said that strict protection is not required. The surface requiring strict protection is fitted toward the bottom surface of the concave fitting portion 2, and sufficient protection is provided based on the theory that the concave fitting portion 2 is covered with a surface that does not require protection. The use of a single board greatly reduces resources and saves resources.
If the thickness is the same as the above, the thickness is twice as large as 2 mm, which makes it extremely thin and easy to hold, and facilitates organizing and storing using the hole 6 at the end of the substrate 7. The present invention is the case of the medium 1 configured as described above.

[0005]

[Operation] The same effect as the conventional method of protecting the medium 1 by the upper and lower boxes is performed by using the concave fitting portion 2 at the lower part of the box and the non-magnetic surface of the medium 1 itself at the upper part of the box. There is no.

[0006]

Embodiments of the present invention will be described below. (A) The substrate 7 is provided with a concave fitting portion 2 such as a circular or card-shaped one adapted to the medium 1. (B) At the center of the concave fitting portion 2, a medium 1 mounting table 3 and a hollow columnar lock 4 matching a central hole of the medium 1 are provided to lock the medium 1. (C) The lower part of the columnar lock 4 is made thin except for the same thickness as the substrate 7. The tip of the columnar medium 4 having a thickness of 1 or more is divided into a plurality of pieces, and a P-shaped five protrusion is provided at the tip to prevent detachment and dropping. (D) Since the thickness of the medium 1 is thinner than the middle of the locking pillar 4 and the tip of the P-shape 5, the medium 1 can be easily inserted into the P-shape by bending into the round shape. The removal is based on the same principle, but both require a conscious force to insert and remove and cannot be inserted or removed by natural friction. (E) An appropriate number of holes 9 are provided at one end of the substrate 7 to facilitate binding and organizing and storing. When the present invention is used in the above structure, the medium 1 is inserted by applying a flat force from above the P-shape 5 by aligning the columnar locking 4 of the concave fitting portion 2 with the center hole of the medium 1. Even if an unconscious force to take out the applied medium 1 is applied, the medium 1 is blocked by the convex lower part of P and does not separate. The medium can be easily removed by lifting the medium 1 flat.

[0007]

According to the present invention, the shape and handling are completely the same as in the prior art, and since the structure is a single plate, the production cost is reduced due to the resource saving and the simplification of the reduction of materials, and the necessity of the bare CD selling which is currently performed is eliminated.
