本発明は、ディジタルオーディオディスク等のディスク
収納ケースの改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improvement in a storage case for discs such as digital audio discs.
従来例の構成とその問題点
近年デジタル録音されたディジタルオーディオディスク
（以下コンパクトディスクと称す）の普及には目ざまし
いものがある。Conventional Structure and Problems There has been a remarkable spread of digitally recorded audio discs (hereinafter referred to as compact discs) in recent years.
以下従来のコンパクトディスク収納ケース、について説
明する。A conventional compact disc storage case will be explained below.

。FIG. 1 shows a conventional compact disc storage case, which consists of a main body 1 and a lid 2 rotatably attached to the negative end of the main body via a hinge 3, both of which are made of plastic. At the center of the main body 1 is a projection 1a that is press-fitted into the center hole of the compact disc to hold the disc.

クトディスク４の信号記録面に傷がつくことはない。FIG. 2 is a side view of a conventional compact disc storage case body 1 with a compact disc 4 stored therein. When stored, there is a gap of approximately one inch between the signal recording surface of the compact disc 4 and the top surface of the compact disc storage case main body 1. The signal recording surface of the compact disc 4 will not be damaged by contact with the top surface of the compact disc storage case body 1.

に傷がつき易いという問題がある。However, with the above configuration, when storing the compact disc 4 in the storage case 1 or removing it from the storage case 1, the signal recording surface of the compact disc 4 and the top surface of the storage case 1 must be The signal recording surface of the compact disc 4 may be scratched. Also, even when the compact disc 4 is stored in the same storage case 2,
There is a problem in that when the compact disc 4 is pressed from above with a finger, it easily comes into contact with the storage case 1, and the signal recording surface of the compact disc 3 is easily scratched.
発明の目的
本発明は、上記従来の問題点を解消するもので簡単な構
成によシディスク信号記録面の損傷を防止できるディス
ク収納ケースを提供するものである。OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems and provides a disk storage case that has a simple structure and can prevent damage to the disk signal recording surface.

Components having the same functions as those in FIGS. 1 and 2 are designated by the same reference numerals, and their explanations will be omitted. 1C is a convex portion provided on the upper surface of the storage case 1, and is disposed at a position where it abuts a non-signal area near the outer periphery of the compact disc. By providing the convex portion on the top surface of the storage case 1 in this way, it is possible to reliably break contact between the signal recording surface of the compact disc and the top surface of the storage case 1, thereby preventing damage to the signal surface of the compact disc.
It is possible to prevent
