Claim 1
Independent Claim
270 words
A storage device for storing flat recording media carriers, such as magnetic tape cassettes, comprising: a housing having a front wall, at least one compartment positioned in said housing, each said compartment being configured to receive a media carrier therein, said front wall having an opening for each said compartment, a transport means for each said compartment adapted to support a media carrier and movable between a first position wherein said media carrier is inserted in one said compartment such that it is generally unexposed and a second position wherein said media carrier is exposed permitting removal of said media carrier from said compartment, each said compartment opening permitting movement of said transport means between said first and second positions, said transport means having a front part exhibiting a surface configured to cover its said compartment opening so as to form part of said front wall when said transport means is in said first position, an indicating means for indicating, when said transport means is in said first position, if a media carrier is contained therein, said transport means having a rear part to which said front part is pivotably connected, said rear part being adapted to support said media carrier, said indicating means being mounted on said front part, said indicating means being actuated, with a media carrier on said rear part, upon pivotal movement of said front part into a position in which it is aligned with said compartment opening, and said front wall having a window positioned and configured to expose said indicating means for optical recognition of said indicating means from the exterior of said housing.
