Claims

[Scope of utility model registration request]

A window is formed in the case housing the recording medium, and a shutter is slidably attached to one side of the case to open the window when in use and close the window when not in use. The shutter is freely engaged with an engagement hole formed in the shutter, and when engaged with the engagement hole, comes into contact with a stopper formed in the shutter and is prevented from moving in the direction of releasing the engagement. A first cam portion that forms a lock pawl and that displaces the lock pawl in the direction of releasing the contact with the stopper when a release member comes into contact with the lock pawl during use, and then an engagement hole. A shutter lock mechanism for a recording/reproducing media device, characterized in that a second cam portion is formed to displace the lock in a direction to release the lock.
