Improvements to magnetic tape handlers.

摘要

A tape tension arm arrangement for selectively disposing a pair of tension rollers (102) supported by respective tension arms (101) in positions appropriate for tape loading or tape drive. Each tension arm (101) is mounted on a pivoted rocker member (107) which is coupled to a driving crank member (104) by a connecting rod (105). The connecting rod (105) engages the rocker member (107) in such a manner that in the tape drive position the tension arm (101) may move against a resilient bias (112) towards the tape threading position, in response to an increase in the tension of the tape. A tape transport system is also described which includes a tape tension arm arrengement of the type described above and a reel mounting device for supporting a reel having an internal support surface. The reel mounting device includes three resiliently coupled reel mounting members each supported between symmetrically disposed pivot points. Each member has a resilient peripheral surface (9) capable of frictionally engaging the internal support surface of the reel and a lever arm capable of releasing the reel from such engagement.
