Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
155 words
A storage device for flat recording media comprising: (a) a housing having a bottom wall, a top wall, two elongate side walls, a rear wall, and an open front side; (b) a slider member for receiving at least one recording medium, the slider member being movably mounted in the housing and having a base portion and a front wall; (c) means for biasing the slider member to an open position out of the housing; (d) means for locking the slider member to a closed position within the housing against the bias of the biasing means; and (e) lifting means for supporting and engaging underneath the recording medium, said lifting means when the device is in the open position raising the recording medium to a lifted position away from the base portion of the slider member and above the front wall of the slider member so that the recording medium is accessible for removal and insertion.
