Rapid drive device for tape transfers

Claim 2

A fast forward and fast rewind drive device for a magnetic tape recording and playback apparatus, the apparatus having a pair of normal speed tape drive means which are alternately engageable for moving the tape from reel to reel at a normal speed in either of two directions, the drive device including: fast speed drive means selectively engageable to move the tape from reel to reel at fast speed in either of said directions; a fast forward manual actuator; a fast rewind manual actuator; control means operated by said manual actuators to selectively engage said drive means; and sensing means included in said control means for sensing which of said normal speed tape drive means is engaged to move the tape at normal speed when the actuators are actuated and connected to control the selective engagement of said fast speed drive means dependent on the direction of tape movement, so that actuation of the fast forward manual actuator operates said control means to engage the fast speed drive means to move the tape from reel to reel at fast speed in the same direction regardless of which direction it happens to be moving at normal speed when the fast forward actuator is actuated, and actuation of the fast rewind manual actuator operates said control means to engage the fast speed drive means to move the tape from reel to reel at fast speed in the direction opposite to the direction of tape movement regardless of which direction it happens to be moving at normal speed when the fast rewind actuator is actuated.

Claim 3

A fast forward and fast rewind drive device according to claim 7 for a magnetic tape recording and playback apparatus, in which said selectively engageable fast speed drive means to move the tape from reel to reel at fast speed in either of two directions includes: oppositely rotating fast speed drive rollers, a pair of drivable spindles for mounting tape reels and associated, respectively, with said drive rollers, and a shiftable idler roller for selectively coupling each spindle to its associated drive roller; said control means operated by said manual actuators to selectively engage said fast speed drive means includes a pair of cams for shifting said idler rollers, and linkages selectively connecting each of said manual actuators to one or the other of said cams; and said sensing means included in said control means for sensing which of said normal speed tape drive means is engaged when the actuators are actuated includes a member for controlling the selective connections provided by said linkages between said manual actuators and said cams dependent on the direction of tape movement at normal speed, so that actuation of the fast forward manual actuator shifts an idler roller to engage the fast speed drive means to drive one of the spindles and move the tape from reel to reel at fast speed in the same direction regardless of which direction it happens to be moving at normal speed when the fast forward actuator is actuated, and actuation of the fast rewind manual actuator shifts an idler roller to engage the fast speed drive means to drive the other spindle and move the tape from reel to reel at fast speed in the direction opposite to the direction of tape movement regardless of which direction it happens to be moving at normal speed when the fast rewind actuator is actuated.

Claim 4

A fast forward and fast rewind drive device according to claim 7 for a magnetic tape recording and playback apparatus, in which said selectively engageable fast speed drive means to move the tape at fast speed in eitHer of two directions includes: oppositely rotating fast speed drive rollers, a pair of drivable spindles for mounting tape reels and associated, respectively, with said drive rollers, and shiftable idler roller means for selectively coupling each spindle to its associated drive roller; said control means operated by said manual actuators to selectively engage said drive means includes a pair of solenoids for shifting said idler roller means, and electrical connections selectively connecting each of said manual actuators to one or the other of said solenoids; and said sensing means included in said control means for sensing which of said normal speed tape drive means is engaged when the actuators are actuated includes a switch member for controlling the selective connections provided between said manual actuators and said solenoids dependent on the direction of tape movement at normal speed, so that actuation of the fast forward manual actuator shifts said idler roller means to engage the fast speed drive means to drive one of the spindles and move the tape from reel to reel at fast speed in the same direction regardless of which direction it happens to be moving at normal speed when the fast forward actuator is actuated, and actuation of the fast rewind manual actuator shifts said idler roller means to engage the fast speed drive means to drive the other spindle and move the tape from reel to reel at fast speed in the direction opposite the direction of tape movement regardless of which direction it happens to be moving at normal speed when the fast rewind actuator is actuated.

Claim 5

A fast forward and fast rewind drive device for a magnetic tape recording and playback apparatus, the apparatus having a pair of normal speed tape drive means which are alternately engageable for moving the tape at a normal speed in either or two directions, the drive device including fast speed drive means selectively engageable to move the tape from reel to reel at fast speed in either of said directions, sensing means for sensing which of said normal speed tape drive means is engaged to move the tape at normal speed, manually actuatable fast forward control means including said sensing means and connected by said sensing means to engage said fast speed drive means to move the tape from reel to reel at fast speed in the same direction as it is moving at normal speed when the fast forward control means is actuated regardless of which direction it happens to be moving at normal speed when the fast forward control means is actuated, and manually actuatable fast rewind control means including said sensing means and connected by said sensing means to engage said fast speed drive means to move the tape from reel to reel at fast speed in the direction opposite to the direction of tape movement at normal speed when the fast rewind control means is actuated regardless of which direction it happens to be moving at normal speed when the fast rewind control means is actuated.

Claim 6
