Abstract
A cartridge for a recording/reproducing medium has a shutter for opening and closing a window opening formed in a casing in which a projection or a gate formed at an outer edge of the shutter is provided not to project from the outer edge. The post-treatment of the gate can be easy to improve productivity, the stroke range of the shutter can be precisely determined; the mounting and dismounting of the shutter on a recording/reproducing device as well as the sliding movement of the shutter is smooth. Further, the quality of the cartridge is improved.
