To avoid releasing of a material layer caused by storing and taking-out a discoid recording medium, and simultaneously, to hold the discoid recording medium without applying a stress in the neighborhood of the hole edge of a central hole.
A plate-like case body 2 in which a port opening 2a capable of inserting and discharging an optical disk D is formed and a guiding path 2c for guiding the optical disk D is formed between the port opening 2a and a storing position 2b, a rib 14 arranged in the depth side in the inserting direction in the guiding path 2c and restricting movement of the optical disk D in the inserting direction, and a release restricting means arranged in the case body 2 through a base end part 31c and restricting the movement of the optical disk D in the discharging direction by forming a narrow part H narrower than the diameter of the optical disk D in the guiding path 2c, and having a projection 31a for holding which allows the movement of the optical disk D by opening the narrow part H by elastic deformation of the base end part 31c, are provided.
