摘要

1314320 Threading tape automatically AMPEX CORP 17 June 1971 [1 July 1970] 28374/71 Heading G5R In an automatic tape threading video recorder designed for a tape supply spool in which an enlarged portion 22, Fig. 2 of a tape leader is gripped by recesses 41 in the spool in such a way that tape on the spool is held firmly in place with the end 22 of the leader projecting freely as shown in Fig. 1, from the spool, threading is initiated by energizing a solenoid 57 causing an idler roller 61 to be moved into contact with both a drive wheel 67 and a flange on the tape supply spool and the following operations then take place: (a) a finger 51 mounted on the same pivot as the roller 61 unpeels the tape leader from the tape spool and guides it towards a pinch roller 69 as the tape spool is rotated, (b the tape leader is gripped by the pinch roller 69 and the drive wheel 67 and pushed and guided forwards past an erase head 27, an arcuate video scanning unit 73, 79 and an audio head 31 to a second pinch roller 93 and drive roller 95, (c) once the tape leader emerges from the second pinch and drive roller and is detected by a lamp 96 and photocell 97, the solenoid 57 is de-energized so that drive is removed from the tape spool and the pinch roller 69, and (d) finally the tape leader impinges upon an arcuate member 112 which guides it around a driven take-up spool 117. A modification (Fig. 6, not shown) is described allowing the tape to be wound in the opposite direction on the take-up spool. The system described also includes a switch 123, which is closed when the tape tension rises at the end of the reel, to stop the machine.
