Abstract
Abstract A housing with one side open to form an entrance for a tape cassette, a slider within the housing and movable toward and away from the entrance, a spring pressing the slider toward the entrance, a latch retaining the spring cassette in the housing against the pressure of said spring, reel-retaining inserts for insertion into the hub of the tape spools, the inward and outward movement relative to the spool hubs being controlled by movement of the slider in the housing, in certain instances the insert being mounted on the slider and in other instances the insert being mounted on the housing.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
181 words
A holder for tape cassettes and the like, the holder comprising a housing having at least one compartment with an open front side to slidably receive a slider in the compartment, a slider in the housing and adapted to linearly transport a cassette into and out of said compartment, the slider having a cassette-engaging rear wall spaced inwardly from said open front side of the housing and the slider having an open and unobstructed front side permitting removal of the cassette from the slider by sliding movement and without tilting, stop means to limit the length of sliding movement of said slider, locking means being provided to hold the slider in its compartment against the force exerted by a spring in the housing and urging the slider into its open position, and cassette reel retention members brakingly engaging into the cassette reel apertures when said slider is locked, said retention members being pivotable in a plane perpendicular to the direction of sliding in response to and upon movement of the slider into its open position thereby disengaging from said reel apertures.
Claim 2
Dependent Claim
181 words
A holder for tape cassettes and the like, the holder comprising a housing having at least one compartment with an open front side to slidably receive a slider in the compartment, a slider in the housing and adapted to linearly transport a cassette into and out of said compartment, the slider having a cassette-engaging rear wall spaced inwardly from said open front side of the housing and the slider having an open and unobstructed front side permitting removal of the cassette from the slider by sliding movement and without tilting, stop means to limit the length of sliding movement of said slider, locking means being provided to hold the slider in its compartment against the force exerted by a spring in the housing and urging the slider into its open position, and cassette reel retention members brakingly engaging into the cassette reel apertures when said slider is locked, said retention members being pivotable in a plane perpendicular to the direction of sliding in response to and upon movement of the slider into its open position thereby disengaging from said reel apertures.
Claim 3
Dependent Claim
117 words
A holder according to claim 1, in which the reel retention members are on the slider and extend toward the open front side of the housing from said rear wall, said reel retention members being pivotable within the housing to tilt out of the reel apertures, and the housing being divided by means of ribs projecting inwards from walls of the housing into two chambers, said ribs extending toward the open front side and parallel to the direction of sliding movement of the slider and cassette, the first of said chambers accommodating the cassette and the other of the chambers accommodating the tilting movement of said reel retention members as the transport slider moves in the housing.
Claim 4
Dependent Claim
83 words
A holder according to claim 2, in which the transport slider has aligned pin extensions adjacent opposite ends of said rear wall, said pin extensions having associated with them slots in the adjacent side walls of the housing and running in the direction of movement of the slider and cassette to limit the ejection movement of the transport slider, and said pin extensions pivotally mounting the transport slider to permit tilting of the retention members into and out of the cassette reel apertures.
Claim 5
Dependent Claim
92 words
A holder according to claim 3, in which the pin extensions and slots are disposed adjacent both chambers and adjacent the ribs therebetween, and said resilient means bearing against the rear wall of the transport slider in said first chamber and in off-centre relation to the pivot axis extending through said pin extensions whereby to tilt the slider under influence of the resilient means to withdraw the retention members from the reel apertures, and means on the slider and adjacent the retention members to limit tilting of the slider in the housing.
Claim 6
Dependent Claim
50 words
A holder according to claim 1, in which the transport slider is L-shaped, with lateral guide walls, forms a drawer which has in its base a pair of counter-slots in which retaining levers are pivotably supported as locking members in alignment with slots in the opposite wall of the housing.
Claim 7
Dependent Claim
33 words
A holder according to claim 5, in which stops are moulded on the base to limit the ejection movement of the slider in co-operation with aligned guide slots in the adjacent covering wall.
Claim 8
Dependent Claim
74 words
A holder according to claim 1, in which the transport slider is T-shaped and has moulded on the back of its longitudinal shank stop teeth which have guide slots in the side wall of the housing associated with them, and in which tongues are cut out of the covering wall and angled towards the inside of the housing, and have associated with them oblique control surfaces on the transverse shanks of the transport slider.
Claim 9
Dependent Claim
70 words
A holder according to claim 1, in which the transport slider is T-shaped and has moulded on the back of its longitudinal shank stop teeth which have guide slots in the covering wall associated with them, and in which tongues are cut out of the transverse shanks of the transport slider and angled towards the inside of the housing, and have associated with them control surfaces on the covering wall.
Claim 10
Dependent Claim
84 words
A holder according to claim 1, in which the transport slider has on the back of its longitudinal shank stop teeth which have guide slots in the covering wall associated with them, and in which levers aligned with the core apertures of the cassette are cut out of the longitudinal shank, which are bent out of the plane of the longitudinal shank and when the cassette is pushed in are pivoted with their free ends into the core apertures to lock the tape spools.
Claim 11
Dependent Claim
36 words
A holder according to claim 1, in which, on the open side of the housing accommodating the cassette, the locking means engages over the inserted cassette and is arranged on one end wall of the housing.
