Disc cartridge, and disc recording and/or reproducing device using the same

Abstract

The present invention is a disk case for containing an optical disc (2), which has a case body (5) that accommodates the optical disc and is provided with a head opening (13) that extends a part of the optical disc across the inner and outer circumferences and faces outward, and has opening and closing The baffle part (22) of the opening of the head, the baffle member (21) that can be installed on the box body movably between the position of the opening of the head and the open position, is arranged on and from the baffle On the elastic displacement piece (36) connected to the connecting arm (35) extended on one side of the part, when the shutter part is in the position of closing the opening part of the head, it is locked with the movement restricting part (45) provided on the box body. A shutter movement restricting portion (41) that restricts movement of the shutter member in the direction of opening the opening for the head.

Description

technical field [0001] The present invention relates to a disc cartridge containing a disc such as an optical disc as an information recording medium, and a disc recording and / or reproducing device using the disc cartridge on the recording medium.

AI Technical Summary

Problems solved by technology

With this disk cartridge, the shutter member can be locked by the shutter movement limiting member to securely close the opening for recording and / or reproduction. Increases the number of parts and complicates assembly

In addition, it is necessary to install the shutter movement limiting member in the space inside the cartridge body, and it is difficult to realize further miniaturization of the disk cartridge itself.
