JPH1131354A - Barrier-free cd and preservation case - Google Patents

Abstract

PROBLEM TO BE SOLVED: To facilitate the discrimination of a signal surface and the taking-out/ in of a recording medium by providing a slope on the outer peripheral side surface of the recording medium, providing a projection on the upper part of a title surface, making the notch of an internal CD fixing part into half and providing CD pressing parts upward/downward. SOLUTION: The slope of elevation angle of about 45 deg. is made to the outer peripheral side surface of a recording medium such as a CD in a state of making a signal surface downward. A round projection is provided on the upper part of a title surface in a preservation case in a state of making an opening/ closing part a right side, the half of the notch of a CD fixing part 6 in the inside of the case is eliminated and the CD pressing parts 7 are provided upward/downward in the inside. When the recording medium is taken out, it is constituted so that upper/lower, left/right are confirmed by the round projection, are opening/closing part is opened to be lifted up and the CD pressing parts are released to take out the recording medium. Thus, the signal surface of the recording medium is discriminated easily by feeling, a load to the CD fixing part in the preservation case is reduced, a fall is prevented by the CD pressing parts and the recording medium can be dealt in stably.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for easily discriminating a signal surface of an optical information recording medium such as a CD, and for easily putting the optical recording medium into and out of a storage case.

[0002]

2. Description of the Related Art At present, an optical information recording medium such as a CD includes:
It is difficult for blind or low-sighted people to recognize the signal surface, and it is difficult to check the open / close section even in the storage case. Also, it is difficult to take out with one hand after opening and closing.

[0003]

This has the following disadvantages. I. With a current optical information recording medium such as a CD, it is difficult for a blind or amblyopia to check the signal surface, and if a finger touches the signal surface at the time of the check, it becomes dirty and cannot be reproduced. B. In the current storage case, it is difficult for blind or low-sighted people to check the opening / closing part, and it takes time to remove. C. The inner part of the optical information recording medium, such as a CD, is easily damaged and difficult to handle with one hand. D. Since the optical information recording medium such as a CD is held by the elasticity of the plastic of the CD fixing portion, the optical information recording medium such as a CD drops by opening and closing the lid when the chip is missing. The present invention has been made to solve the above drawbacks.

[0004]

In order to achieve the above-mentioned object, in the present invention, an outer peripheral side surface of an optical information recording medium such as a CD is inclined (FIGS. 1 and 2). And
The storage case is provided with a protrusion (4) at the top of the title surface. Furthermore, the lower half of the plastic notch in the inner CD fixing portion is eliminated (6), and a CD holder (7) is provided on the upper and lower sides.

[0005]

Embodiments of the present invention will be described below. I. An outer peripheral side surface of an optical information recording medium such as a CD is inclined at an elevation angle of about 45 degrees (FIGS. 1 and 2) with the signal surface facing down. B. The storage case is provided with a round projection (4) on the upper part of the title surface with the opening / closing part being on the right side. C. Eliminate the lower half of the plastic cut in the CD fixing part inside the storage case (6). D. CD holders are provided above and below the storage case (7). The present invention has the above configuration. When using the present invention, when removing an optical information recording medium such as a CD, the round projections at the top of the title surface are used to check the top, bottom, left and right of the storage case. Open the opening / closing part and insert the index finger (middle finger) directly into CD
The optical information recording medium such as a CD is released from the upper CD holder by releasing the CD from the lower CD holder by hooking the iso-optical information recording medium on the center side surface and lifting the outer peripheral surface vertically with the thumb, and lifting the CD forward. Release and remove. In addition, when storing, an optical information recording medium such as a CD is hooked to the central side surface with the index finger (middle finger), the outer peripheral side surface is held with the thumb, and slightly tilted backward, and inserted between the upper CD holder and the storage case fixing portion. By pressing the CD vertically with your thumb,
Fix it between the lower CD holder and the storage case fixing part.

[0006]

By using the present invention, the optical information recording medium such as a CD is wrapped with the index finger (middle finger) and the thumb when the signal surface is down, and is easily caught and held. With the face up, it is difficult to wrap it with your finger and it is hard to catch because it is hard to catch. Using this tactile sensation, the signal surface of an optical information recording medium such as a CD is
It can be easily identified. Mainly CD (12cm, 8cm),
CD-R, CD-V, CD-I, CD-ROM, CD-
It is effective for a medium that records information only on one side such as ROM XA and DVD (single-sided single layer / single-sided multilayer). It is easy to hold and the B (2) plane is difficult to hold. The storage case can be opened and closed instantly by judging top, bottom, left and right by providing a projection at the top of the title surface. Eliminates the lower half of the plastic notch in the internal CD fixing part, reducing the load on the CD fixing part. Furthermore, it is hard to fall down by providing a CD holder above and below the inside, and it is more reliable when taking out And CD
It can handle iso-optical information recording media. It is mainly effective for a disk-shaped storage medium storage case, and can also be applied to a connection type multi-layer storage case capable of storing five or more sheets.
