Abstract
An intermediate shell is held rotatably by an upper shell and a lower shell without using a spring and a pair of the shutter members is opened/closed by a rotation of the intermediate shell. Not only with the pair of the shutter members completely closed, but also closed incompletely or opened completely, this disc cartridge can be loaded on a recording/reproducing apparatus and upon the loading, the opening portion is opened securely. This disc cartridge comprises: a cartridge case (12) in which a disc accommodating chamber (16) is formed between an upper shell (13) and an intermediate shell (14) by overlaying the upper shell (13), the intermediate shell (14) and a lower shell (15), while the intermediate shell (14) is supported rotatably by the upper shell (13) and the lower shell (15); an optical disc (11) which is accommodated rotatably in the disc accommodating chamber (16) while part of the same optical disc is exposed through opening portions (42, 25) provided in the intermediate shell (14) and the lower shell (15); and a pair of shutter members (18a, 18b) mounted on the intermediate shell (14), capable of opening/closing the opening portions (42, 25). The upper shell (13) and the lower shell (15) are provided with an operating window (30) for rotating the intermediate shell (14) and a driven portion (43), which is engaged with a rack bar (70) passing outside the operating window (30) for rotating the intermediate shell (14) up to a predetermined position, is provided on an external peripheral face of the intermediate shell (14).
