Claims

[Scope of utility model registration request]

A magnetic sheet disk is rotatably housed inside, and a magnetic head insertion window is provided to expose the sheet disk to the outside, and a shutter plate for opening and closing this window is arranged along one side edge so as to be able to reciprocate. In the magnetic sheet jacket, a stepped shutter guide is provided on one side periphery of the sheet jacket, and a resilient member is provided on the shutter plate to press against the guide, so that the reciprocating movement of the shutter plate can be controlled. At times, the shutter plate protrudes in and out from one side edge of the sheet jacket along the shutter guide to selectively engage an engagement protrusion for opening a shutter and an engagement protrusion for closing a shutter provided on a recording/reproducing device. A magnetic sheet jacket characterized in that it can be freely engaged.
