Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
248 words
A holder for tape cassettes and the like comprising a housing for receiving the cassette and having broad and spaced sidewalls to receive a cassette therebetween and having narrow end and base walls between the sidewalls and also having a narrow slot-shaped entrance opposite one of said narrow walls whereby to receive and carry the cassette with the reel axes extending transversely through the broad sidewalls, manipulating means on the housing for engaging the cassette when introduced into the housing, said manipulating means including a cassette-engaging portion swingable relative to said narrow walls and about at least one axis extending transversely through the planes of the sidewalls to swing with the cassette as the cassette swings inwardly and outwardly of the entrance, said manipulating means including a spring urging said cassette-engaging portion generally toward the entrance for thrusting the cassette outwardly through the entrance, and said manipulating means also including locking means connected with the housing and opposing the thrust of the spring to cooperate with the cassette-engaging portion in retaining the cassette in the housing, and the manipulating means including a pair of elongated flexible arms and a cam mounted on each of the arms and facing inwardly of the housing adjacent the entrance to confront, engage and obstruct the cassette as the cassette emerges partly through the entrance under the initial thrust provided by the spring and also retaining the cassette against falling out by tipping about axes lying parallel to the sidewalls of the housing.
Claim 2
Dependent Claim
248 words
A holder for tape cassettes and the like comprising a housing for receiving the cassette and having broad and spaced sidewalls to receive a cassette therebetween and having narrow end and base walls between the sidewalls and also having a narrow slot-shaped entrance opposite one of said narrow walls whereby to receive and carry the cassette with the reel axes extending transversely through the broad sidewalls, manipulating means on the housing for engaging the cassette when introduced into the housing, said manipulating means including a cassette-engaging portion swingable relative to said narrow walls and about at least one axis extending transversely through the planes of the sidewalls to swing with the cassette as the cassette swings inwardly and outwardly of the entrance, said manipulating means including a spring urging said cassette-engaging portion generally toward the entrance for thrusting the cassette outwardly through the entrance, and said manipulating means also including locking means connected with the housing and opposing the thrust of the spring to cooperate with the cassette-engaging portion in retaining the cassette in the housing, and the manipulating means including a pair of elongated flexible arms and a cam mounted on each of the arms and facing inwardly of the housing adjacent the entrance to confront, engage and obstruct the cassette as the cassette emerges partly through the entrance under the initial thrust provided by the spring and also retaining the cassette against falling out by tipping about axes lying parallel to the sidewalls of the housing.
Claim 3
Dependent Claim
151 words
A holder according to claim 1 and the cassette-engaging portion comprising an elongate carrier with one end hinged to the housing for swinging movement between a first position substantially within the housing and along the entrance and a second position projecting partly out of and partly into the housing and oriented transversely of and through the entrance, the carrier having one closed narrow side traversing said entrance in said first position and also having a second closed narrow side adjacent said one side and also adjacent the hinge, and the carrier having a narrow open side opposite one of said closed sides to accept the cassette therethrough, and the flexible arm being mounted on the carrier and the cam projecting slightly across the elongate carrier to engage and yieldably obstruct sliding removal of the cassette from the carrier, said cam being oriented with an oblique camming face confronting said open side.
Claim 4
Dependent Claim
27 words
A holder according to claim 1 in which the cam on the cassette-engaging portion projecting transversely of the sidewalls for holding the tape coils of the cassette.
Claim 5
Dependent Claim

A holder according to claim 3 in which the cassette-engaging portion includes housing parts which can be pivoted together with the cassette.
Claim 6
Dependent Claim
33 words
A holder according to claim 1 in which the spring comprises a helical spring which is anchored to the housing, and to the cassette-engaging portion which can be pivoted out with the cassette.
Claim 7
Dependent Claim
26 words
A holder according to claim 1 in which the cassette-engaging portion is mounted on the housing for linear displacement movement in addition to the pivoting movement.
Claim 8
Dependent Claim
39 words
A holder for a tape cassette according to claim 1 and the locking means acting in opposition to said spring and cooperating with the thrust produced by the spring in enhancing the retention of the cassette in the housing.
Claim 9
Dependent Claim
34 words
The holder for tape cassettes according to claim 1 and said cassette-engaging portion and cam cooperatively obstructing movement of the cassette except in a direction parallel to the side walls and through the entrance.
Claim 10
Dependent Claim
122 words
The holder for tape cassettes set forth in claim 1 and the housing having two end walls adjacent opposite ends of the entrance, and said cassette-engaging portion comprising an elongate carrier on the housing and removably mounting a cassette thereon, guide means on the housing and carrier and permitting limited coordinated swinging and sliding of the elongate carrier between a first position substantially within the housing and along the entrance and a second position projecting partly out of and partly into the housing and oriented transversely of and through the entrance, and the flexible arm being mounted on the carrier and the cam projecting slightly across the elongate carrier to engage and yieldably obstruct sliding removal of the cassette from the carrier.
Claim 11
Dependent Claim
112 words
The holder for tape cassettes set forth in claim 9 and the elongate carrier having one end over which the cassette may slide for removal said one end being confined with the housing in the first position of the carrier, said guide means on the housing and carrier including a slot on one and a projection on the other and disposed in the slot and guided thereby, the slot extending in an oblique direction toward the entrance and toward said one end of the carrier when the carrier is disposed in said first position, whereby to permit movement of the carrier in said oblique direction and coordinated swinging to said second position.
