Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
190 words
A tape transport device for cassette recorders, wherein a motor drives a flywheel and an idler wheel and wherein the capstan is formed by the shaft of said flywheel, said device comprising: a wind member wherein a first gear is releasably coupled to a second gear coaxial with it, said second gear meshing with a pinion rigid with said idler wheel; a freely rotatable rewind member; a flip-over arm carrying upper and lower twin gears at one end, said flip-over arm being movable into a first position, wherein the upper one of its twin gears engages said first gear of the wind member and the lower one engages a gear which is rigid and coaxial with said flywheel, to transmit thereby the drive of said motor to said wind member, and is movable into a second position, wherein its upper twin gear engages said rewind member while its lower twin gear engages a gear which is rigid and coaxial with the idler wheel, to transmit thereby a rewind motion from the motor to the rewind member, and is movable into a third, inoperative position intermediate its first and second position.
Claim 2
Dependent Claim
190 words
A tape transport device for cassette recorders, wherein a motor drives a flywheel and an idler wheel and wherein the capstan is formed by the shaft of said flywheel, said device comprising: a wind member wherein a first gear is releasably coupled to a second gear coaxial with it, said second gear meshing with a pinion rigid with said idler wheel; a freely rotatable rewind member; a flip-over arm carrying upper and lower twin gears at one end, said flip-over arm being movable into a first position, wherein the upper one of its twin gears engages said first gear of the wind member and the lower one engages a gear which is rigid and coaxial with said flywheel, to transmit thereby the drive of said motor to said wind member, and is movable into a second position, wherein its upper twin gear engages said rewind member while its lower twin gear engages a gear which is rigid and coaxial with the idler wheel, to transmit thereby a rewind motion from the motor to the rewind member, and is movable into a third, inoperative position intermediate its first and second position.
Claim 3
Dependent Claim
40 words
A tape transport device according to claim 1, wherein the wind member comprises: a fist gear rigid with its shaft; a second gear axially slidable on said shaft; and a friction ring interposed between said first and said second gears.
Claim 4
Dependent Claim
58 words
A tape transport device according to claim 1, wherein the flip-over arm has a first slot intermediate its ends and a second slot at its end opposite said twin gears, a stationary pin engaging said first slot and said flip-over arm being linked to a control lever by a pin of said control lever engaging said second slot.
Claim 5
Dependent Claim
62 words
A tape transport device according to claim 1, further comprising: a pivotable arm carrying a recording head and an erasing head; a pressure roller for pressing the tape of the cassette against the capstan, said pressure roller being rotatable at one end of a bracket, whose other end is pivotably mounted on said arm, said bracket being spring biased against said capstan.
Claim 6
Dependent Claim
44 words
A tape transport device according to claim 4, wherein the counterclockwise rotation of said arm releases said second gear from said first gear of said wind member and its clockwise rotation frictionally engages said second gear to said first gear of said wind member.
