The CD case of the present invention comprises:
A case body that can hold a CD, and a CD inside the case body
It is characterized by comprising a CD holding shelf provided along the loading / unloading direction, and a CD locking member arranged parallel to the CD holding shelf at a distance that allows the CD to pass through.

[0010] With this configuration, the CD accommodated in the case body is restrained by the CD holding shelf and the CD locking member, so that the stored CD can be safely stored. Since the CD can be stored simply by inserting the CD between the CD holding shelf and the CD locking member, and can be detached from the space between the CD holding shelf and the CD locking member by moving the stored CD in reverse. CD loading and unloading operations are extremely easy.

[0011] At least one of the CD holding shelf and the CD holding member has elasticity, and at least one of the CD holding member and the CD holding shelf is provided with an engaging projection protruding toward the CD passage. Since the outer periphery of the CD housed between the and the CD locking member abuts on the engaging projection and is prevented from moving, the movement and detachment of the CD during housing can be prevented. When the CD comes into contact with the engaging projection during the loading / unloading operation, at least one of the CD holding shelf and the CD engaging member is elastically deformed by the force applied to the CD, so that the CD passing path near the tip of the engaging projection is expanded, and the CD is released. Since it is possible to pass the CD, the operability of inserting and removing the CD is not impaired.

By providing an elastic holding member for detachably holding the CD housed between the CD holding shelf and the CD locking member on the inner surface of the case body, the CD housed in the case body can be provided at a plurality of places. Since the CD is restrained, the function of holding the CD is enhanced, and the earthquake resistance, impact resistance, and the like are improved.

By making the length of the CD locking member shorter than that of the CD holding shelf, the exposed portion of the CD holding shelf in the case main body increases, so that the outer periphery of the CD is placed and pushed into the exposed portion of the CD holding shelf. Only by this, the CD can be reliably inserted between the CD locking member and the CD holding shelf, the positioning can be easily performed, and the operability when the CD is stored is improved. In this case, by thinning the vicinity of the tip of the CD locking member toward the tip and providing a smooth tapered curved surface on the CD passage path side, the CD can be tilted obliquely with respect to the CD holding shelf. Since it is possible to take in and out between the CD locking member and the CD holding shelf, the operability of taking in and out is further improved.

By providing an opening / closing lid rotatably supported by the case main body and capable of closing the opening of the case main body, the case main body can be hermetically sealed when a CD is stored or not used. Further, it is possible to prevent the CD from being detached or to prevent dust or foreign matter from entering, thereby further improving safety.
