US4370682A — Tape loading apparatus in a recording and/or repr…

Claim 1

Independent Claim 170 words

A video cassette tape player comprising means for supporting a tape supply reel and a tape takeup reel with a length of tape extending between said reels; separate motor means individually associated with each of said reels for selectively transporting said tape back and forth between said reels; means for pulling said length of tape from said reels and into a predetermined tape path; means for normally holding said reels immobile against random rotation; means responsive to a playback command signal for releasing said holding means, starting said pulling means, and energizing said motor means; means for feeding back a control signal for applying a minimum driving power to each of said motor means in order to maintain a predetermined and balanced tension in said length of said tape while it is being pulled into said predetermined tape path; and means responsive to said tape reaching said predetermined tape path for reapplying said holding means, stopping said pulling means, and controlling the power applied to each of said motor means.

Claim 2

Dependent Claim 170 words

A video cassette tape player comprising means for supporting a tape supply reel and a tape takeup reel with a length of tape extending between said reels; separate motor means individually associated with each of said reels for selectively transporting said tape back and forth between said reels; means for pulling said length of tape from said reels and into a predetermined tape path; means for normally holding said reels immobile against random rotation; means responsive to a playback command signal for releasing said holding means, starting said pulling means, and energizing said motor means; means for feeding back a control signal for applying a minimum driving power to each of said motor means in order to maintain a predetermined and balanced tension in said length of said tape while it is being pulled into said predetermined tape path; and means responsive to said tape reaching said predetermined tape path for reapplying said holding means, stopping said pulling means, and controlling the power applied to each of said motor means.

Claim 3

Dependent Claim 164 words

A tape-loading device in an apparatus for recording and/or reproducing information signals on and/or from a recording tape, said tape-loading device comprising: a first tape drawing out means rotating to draw tape out of a cassette; a second tape drawing out means rotating to draw the tape out of the cassette; means for causing the first and second tape drawing out means to rotate in a mutually interrelated manner such that the two tape drawing out means start operating at respectively different instants of time, a supply-side reel motor for driving a reel disc on a tape-supply side in the cassette; a takeup-side reel motor for driving a reel disc on a takeup-side in the cassette; and an electrical circuit operating when the tape-loading means draws out the tape to apply voltages to the reel motors on the supply-side and the takeup-side such that an equal rotational torque is produced in each of the two motors in the direction of winding up the tape.

Claim 4

Dependent Claim 164 words

A tape-loading device in an apparatus for recording and/or reproducing information signals on and/or from a recording tape, said tape-loading device comprising: a first tape drawing out means rotating to draw tape out of a cassette; a second tape drawing out means rotating to draw the tape out of the cassette; means for causing the first and second tape drawing out means to rotate in a mutually interrelated manner such that the two tape drawing out means start operating at respectively different instants of time, a supply-side reel motor for driving a reel disc on a tape-supply side in the cassette; a takeup-side reel motor for driving a reel disc on a takeup-side in the cassette; and an electrical circuit operating when the tape-loading means draws out the tape to apply voltages to the reel motors on the supply-side and the takeup-side such that an equal rotational torque is produced in each of the two motors in the direction of winding up the tape.

Claim 5

Dependent Claim 29 words

A tape-loading device as claimed in claim 2 and means for locking the first and second tape drawing out means at a final position after drawing out the tape.

Claim 6

Dependent Claim 60 words

A tape-loading device as claimed in claim 2 further having circuit means for applying to the supply-side reel motor a voltage such that a rotational torque is produed in the supply-side motor for winding up the tape when the tape-loading means moves in the direction opposite to that in which it moves at the time of drawing out the tape.
