Abstract
Abstract A cassette tape recorder comprises a cassette holder having a pair of spaced arm portions each having at its leading end a recess; a shaft spanned between a pair of spaced brackets in a manner that an end of the shaft is projected outwardly from one of the brackets to form an exposed shaft section, the recesses of the receiving therein the shaft to permit the cassette holder to be pivotable about the shaft; an arm member having an opening through which the exposed shaft section passes to permit the arm member to be pivotable about the exposed shaft section; a connector to provide for simultaneous pivotting movements of the cassette holder and the arm member under a condition wherein the arm portions of the cassette holder are operatively mounted on the shaft; biasing the arm member to cause it pivot in one direction about the exposed shaft section; and a brake for causing the pivotting movement of the arm member in the one direction to be damped.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
177 words
A cassette tape recorder having a housing with an opening therein, and including: a shaft extending between spaced parallel brackets mounted on said housing adjacent to said opening; a cassette holder for holding therein a tape cassette and having a pair of arms pivotally mounted on said shaft to rotate thereabout between a loading position in which said holder is outside said opening for loading and unloading of said cassette, and an operative position in which said holder is inside said opening; a slip-friction member axially slidably mounted on said shaft and engaged loosely with one said holder arm for unitary rotation therewith and having a surface for making contact with a stationary surface when said slip-friction member axially slides toward said stationary surface; first biasing means for urging said holder toward said loading position; and second biasing means for urging said slip-friction member toward said stationary surface to produce slip friction between said contacting surfaces when said holder is rotated from said operative position to said loading position by the action of said first biasing means.
Claim 2
Dependent Claim
177 words
A cassette tape recorder having a housing with an opening therein, and including: a shaft extending between spaced parallel brackets mounted on said housing adjacent to said opening; a cassette holder for holding therein a tape cassette and having a pair of arms pivotally mounted on said shaft to rotate thereabout between a loading position in which said holder is outside said opening for loading and unloading of said cassette, and an operative position in which said holder is inside said opening; a slip-friction member axially slidably mounted on said shaft and engaged loosely with one said holder arm for unitary rotation therewith and having a surface for making contact with a stationary surface when said slip-friction member axially slides toward said stationary surface; first biasing means for urging said holder toward said loading position; and second biasing means for urging said slip-friction member toward said stationary surface to produce slip friction between said contacting surfaces when said holder is rotated from said operative position to said loading position by the action of said first biasing means.
Claim 3
Dependent Claim
27 words
A cassette tape recorder as claimed in claim 1 wherein each of said arms of the holder is formed with a recess in which said shaft engages.
Claim 4
Dependent Claim
19 words
A cassette tape recorder as claimed in claim 1 wherein said holder arms are both located between said brackets.
Claim 5
Dependent Claim
37 words
A cassette tape recorder as claimed in claims 1 or 2 wherein said slip-friction member and said one holder arm are connected by an arrangement including a pin and a pair of spaced members engaging said pin.
Claim 6
Dependent Claim
36 words
A cassette tape recorder as claimed in claim 1 wherein said shaft extends outwardly through one of said brackets, and wherein said slip-friction member is pivotally slidably mounted on the outwardly extending portion of said shaft.
Claim 7
Dependent Claim
40 words
A cassette tape recorder as claimed in claim 1 wherein said stationary surface is formed by a rotationally stationary member located between one of said brackets, to which said stationary member is secured, and the surface of said slip-friction member.
Claim 8
Dependent Claim
16 words
A cassette tape recorder as claimed in claim 1 wherein said second biasing means is adjustable.
Claim 9
Dependent Claim
