Tape player phonograph adapter permitting operation of tape cartridges or cassettes on conventional phonograph

Claim 2

An adapter for enabling the operation of tape cartridges or cassettes on a conventional phonograph record player having a record turntable and a tone arm with a phonograph cartridge and a needle, said adapter including in combination: a housing for tape transducer apparatus having a cartridge/cassette-receiving chamber and including at least a tape transducer head and a tape-driving capstan; driven turntable means rotatably mounted in the housing and positioned to be rotated by the record turntable when the housing is placed on the record turntable; means coupled with the driven turntable means for rotating the tape-driving capstan; and means coupled with the tape transducer head for vibrating said needle in accordance with the output of such head.

Claim 3

The combination according to claim 1 wherein said record player has a center spindle and wherein the housing for tape transducer apparatus has a locating aperture therein for receiving the center spindle of the phonograph record player, with said locating aperture serving to locate the housing on the record turntable.

Claim 4

An adapter for enabling the operation of tape cartridges or cassettes on a conventional phonograph record player having a record turntable and tone arm with a phonograph cartridge and a needle, said adapter including in combination: a housing for tape reproducing apparatus having a cartridge/cassette-receiving chamber and including at least a tape reproducing head and a tape-driving capstan; driven turntable means rotatably mounted in the housing and positioned to rest on and be rotated by the record turntable when the housing is placed on the record turntable, the driven turntable means supporting the housing on the record turntable; means coupled with the driven turntable means for rotating the tape-driving capstan; output transducer means for providing a representation of the output of the tape reproducing head; means for coupling the tape reproducing head with the output traNsducer means; and needle-receiving means coupled with the output transducer means for receiving the record player needle for vibrating said needle in accordance with the output of the tape reproducing head.

Claim 5

An adapter for enabling the operation of tape cartridges or cassettes on a conventional phonograph record player having a record turntable and tone arm with a phonograph cartridge and a needle, said adapter including in combination: a housing for tape reproducing apparatus having a cartridge/cassette-receiving chamber and including at least a tape reproducing head and a tape-driving capstan; driven turntable means rotatably mounted in the housing and positioned to rest on and be rotated by the record turntable when the housing is placed on the record turntable, the driven turntable means supporting the housing on the record turntable; means coupled with the driven turntable means for rotating the tape-driving capstan; output transducer means for providing a representation of the output of the tape reproducing head; means for coupling the tape reproducing head with the output traNsducer means; and needle-receiving means coupled with the output transducer means for receiving the record player needle for vibrating said needle in accordance with the output of the tape reproducing head.

Claim 6

The combination according to claim 3 wherein the output transducer means includes an output phonograph cartridge driven by input signals obtained from the means coupling the tape reproducing head with the output transducer means.

Claim 7

The combination according to claim 4 wherein the needle-receiving means includes a substantially flat plate having a needle-receiving groove therein, with the plate including an extension connected to the output phonograph cartridge for vibration thereby.

Claim 8

The combination according to claim 3 wherein said record player has a center spindle and wherein the housing for the tape reproducing apparatus has a locating aperture therein for receiving the center spindle of the phonograph record player, with said locating aperture serving to locate the housing on the record turntable, the housing further including means for supporting the needle-receiving means at a predetermined distance from the locating aperture along the arc normally traversed by the needle of the phonograph record player.

Claim 9

The combination according to claim 6 wherein the needle-receiving means includes a plate having a substantially longitudinal needle-receiving slot with said slot being substantially perpendicular to the arc normally traversed by the needle in the record player.

Claim 10

The combination according to claim 7 wherein the output transducer means includes an output phonograph cartridge supplied with input signals from the means coupling the tape reproducing head with the output transducer means, and wherein the output phonograph cartridge is place in an inverted position with respect to the phonograph record player tone arm, with the plate being connected to the output phonograph cartridge for vibration thereby in accordance with said input signals.

Claim 11

The combination according to claim 3 wherein the coupling means includes amplifier means, and further including a generator operated by the rotation of the record turntable for supplying operating power to the amplifier means.

Claim 12

The combination according to claim 9 wherein the generator includes an alternately magnetized ring on the driven turntable means and further includes a pickup coil mounted at a fixed location in the housing and positioned to be responsive to the changes in the magnetic field of the magnetized ring passing by said fixed location when the driven turntable means is rotated for producing an alternating voltage used as the source of power for operating said amplifier means.

Claim 13

The combination according to claim 10 further including rectifier means responsive to the alternating voltage for producing a DC operating voltage for the amplifier means.
