Abstract
Abstract For use with tape-recording equipment preferably using a cassette which has a pair of reels and a magnetic tape, the forward direction of movement of the tape being the record direction and the reverse direction being the rewind or playback direction, the apparatus including electric actuators which pull in and lock the tape-recording apparatus in either the record of the playback mode, the position being held without the continued application of electrical power to the electric actuators, and further including a release electric actuator which unlatches the record and playback actuators, and an interlock system preventing actuation of both modes of operation.

Claim 4
Dependent Claim
194 words
Apparatus adapted for transporting recording media between first and second reels and comprising; a. first and second spindles respectively adapted for supporting a reel carrying a recording medium; b. means including a motor adapted for operatively driving either of said spindles in a selected rotative direction; c. first means selectively operable for coupling said motor to said first spindle and including a first actuator adapted for movement between an inactive position and an active position; d. second means selectively operable for coupling said motor to said second spindle and including a second actuator adapted for movement between an inactive position and an active position; e. latching means operatively arranged between said first and second actuators and responsive to movement of either one of said actuators toward its said active position for releasably retaining the other of said actuators in its said inactive position and for releasably retaining said one actuator in its said active position; and, f. third means selectively operable for uncoupling said motor from said first and second spindles and including a third actuator coupled to said latching means and adapted for releasing said latching means from said first and second actuators.
Claim 5
Dependent Claim
194 words
Apparatus adapted for transporting recording media between first and second reels and comprising; a. first and second spindles respectively adapted for supporting a reel carrying a recording medium; b. means including a motor adapted for operatively driving either of said spindles in a selected rotative direction; c. first means selectively operable for coupling said motor to said first spindle and including a first actuator adapted for movement between an inactive position and an active position; d. second means selectively operable for coupling said motor to said second spindle and including a second actuator adapted for movement between an inactive position and an active position; e. latching means operatively arranged between said first and second actuators and responsive to movement of either one of said actuators toward its said active position for releasably retaining the other of said actuators in its said inactive position and for releasably retaining said one actuator in its said active position; and, f. third means selectively operable for uncoupling said motor from said first and second spindles and including a third actuator coupled to said latching means and adapted for releasing said latching means from said first and second actuators.
Claim 6
Dependent Claim
