Claims

[Scope of utility model registration request]

A recess is formed in a case containing a recording medium, and a slider that is moved between a first position indicating a first state and a second position indicating a second state can be freely slid into the recess. A recording/reproducing medium characterized in that a claw piece is provided on the case or the slider and can be broken off to restrict the sliding movement of the slider and stop the slider at one of the two positions. A device status indicator.
