Magnetic tape handler |
摘要 |
A tape tension arm arrangement for selectively disposing a pair of tension rollers supported by respective tension arms in positions appropriate for tape loading or tape drive. Each tension arm is mounted on a pivoted rocker member which is coupled to a driving crank member by a connecting rod. The connecting rod engages the rocker member in such a manner that in the tape drive position the tension arm may move against a resilient bias 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 arrangement 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 capable of frictionally engaging the internal support surface of the reel and a lever arm capable of releasing the reel from such engagement.
