Abstract
1377393 Tape transport/loading RCA CORPORATION 21 March 1972 [29 March 1971] 8113/71 Heading G5R In a tape transport system, a reverse torque is applied to a tape supply reel at the start of transducing movement in accordance with the number of revolutions made by the reel during tape threading/loading. In the arrangement shown, two motors 78 are activated at a switch 80 to cause two pins 72 to be moved along two guideways 74, thereby to withdraw tape 66 from a reel 60 in a cassette 64. Simultaneously, a detector 88 senses the rotations of reel 60 and despatches signals to a counter 96 via a gate 92, but when the tape is engaged with a head 68 and capstan 70, a switch 98 is closed by the pin 72, and a pulse is produced which closes gate 92 and hence stops the counter 96. When therefore a switch 110 is closed to activate the capstan 70 and take up reel drive 86, a further switch 108 is automatically closed and a converter 104 controls a reel drive 84 to supply a reverse torque to reel 60 in accordance with the count of counter 96. A further arrangement is described with reference to Fig. 1 (not shown).
