Abstract
Abstract Disclosed is apparatus for receiving and enabling translatory motion of a tape cassette including first and second guides carried by the tape recording and/or playback device pivotable about mutually perpendicular axes parallel to the plane of the cassette and engageable with the cassette along its opposite sides. One of the guides is biased toward the cassette and the other guide whereby the cassette may be translated in planes parallel one to the other against the bias of such one guide with the other guide following the movement of the cassette.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
157 words
Apparatus for receiving and enabling translatory motion of a tape cassette in a tape recording and/or playback device comprising: means defining a cavity for receiving a tape cassette having a planar configuration, a first guide superposed over and engageable with the cassette when received within said cavity and pivotal about a first predetermined axis parallel to the plane of the cassette, a second guide underlying the cassette when received within said cavity and on the opposite side thereof from said first guide, said second guide being pivotal about a second predetermined axis parallel to the plane of the cassette and normal to said first axis, and means for biasing said second guide for movement in a direction toward said first guide to engage the cassette and maintain the latter between said first and second guides whereby the cassette is movable against the bias of said biasing means in a direction normal to the plane of the cassette.
Claim 2
Dependent Claim
157 words
Apparatus for receiving and enabling translatory motion of a tape cassette in a tape recording and/or playback device comprising: means defining a cavity for receiving a tape cassette having a planar configuration, a first guide superposed over and engageable with the cassette when received within said cavity and pivotal about a first predetermined axis parallel to the plane of the cassette, a second guide underlying the cassette when received within said cavity and on the opposite side thereof from said first guide, said second guide being pivotal about a second predetermined axis parallel to the plane of the cassette and normal to said first axis, and means for biasing said second guide for movement in a direction toward said first guide to engage the cassette and maintain the latter between said first and second guides whereby the cassette is movable against the bias of said biasing means in a direction normal to the plane of the cassette.
Claim 3
Dependent Claim
12 words
Apparatus according to claim 1 wherein said biasing means includes a spring.
Claim 4
Dependent Claim
19 words
Apparatus according to claim 2 including means for preventing lateral movement of the cassette when inserted into said cavity.
Claim 5
Dependent Claim
74 words
Apparatus according to claim 1 wherein said biasing means includes a spring, a second guide including a pair of spaced guide elements each pivotal about a predetermined axis parallel to one another and the plane of the cassette and normal to said first axis, said guide elements having portions spaced from said second axis and being adapted to engage the cassette adjacent opposite ends, said pair of guide elements being pivotal in opposite directions.
Claim 6
Dependent Claim
59 words
Apparatus according to claim 1 wherein said second guide includes a pair of spaced guide elements each pivotal about a predetermined axis parallel to one another and the plane of the cassette and normal to said first axis, said guide elements having portions spaced from said second axis and being adapted to engage the cassette adjacent opposite ends thereof.
Claim 7
Dependent Claim
16 words
Apparatus according to claim 5 wherein said pair of guide elements are pivotal in opposite directions.
Claim 8
Dependent Claim
27 words
Apparatus according to claim 5 wherein said first guide includes a fork-like element with the individual prongs thereof adapted to engage the cassette adjacent its opposite ends.
Claim 9
Dependent Claim
26 words
Apparatus according to claim 5 wherein the edges of said pair of guide elements closest to the direction in which the cassette is inserted are rounded.
Claim 10
Dependent Claim
43 words
Apparatus according to claim 5 including means for limiting the rotation of said second guide to prevent said second guide portions from obtaining positions directly between the cassette and said second axis and in a plane normal to the plane of the cassette.
