Abstract
A tape transport assembly typically employing a belt drive for the tape comprises: A. a pair of reels for tape to be transported from a supply roll on one reel to a take-up roll on the other reel, B. at least one peripheral support to peripherally engage one of said reels to position same upon initial reception thereof in said assembly, and C. centering support means carried by the assembly for relative movement into and out of centrally supporting position in which said one reel is displaced out of peripheral engagement with said peripheral support and is centrally supported for rotation.
Claims19
In a tape transport assembly that includes
- a. a pair of reels for tape to be transported from a supply roll on one reel to a take-up roll on the other reel,
- b. at least one initial support to initially engage one of said reels to position same upon initial reception thereof in said assembly,
- c. centering support means carried by the assembly for relative movement into and out of centrally supporting position in which said one reel is displaced out of engagement with said initial support and is centrally supported for rotation, and
- d. an endless belt located to arcuately engage the tape rolls on the respective reels for rotating the rolls and reels to effect said transport in response to endwise travel of the belt, the belt remaining in proximity with the tape roll on said one reel during said reel displacement by said centering support means.

In a tape transport assembly that includes
- a. a pair of reels for tape to be transported from a supply roll on one reel to a take-up roll on the other reel, p1 b. at least one peripheral support to peripherally engage one of said reels to position same upon initial reception thereof in said assembly, and
- c. centering support means carried by the assembly for relative movement into and out of centrally supporting position in which said one reel is displaced out of peripheral engagement with said peripheral support and is centrally supported for rotation, said centering support means comprising a plunger, and there being actuating means to bodily advance and retract the plunger into and out of reel centrally supporting position, said actuating means comprising a lever operatively connected with the plunger, and structure supporting the lever to pivot in plunger advancing and retracting directions,
- d. and including a case for said assembly, the case having a closure, the lever projecting free of the case for manual operation and the lever operatively connected with the closure to advance the plunger into reel centering position in response to displacement of the closure to closed position.
In a tape transport assembly that includes
- a. a pair of reels for tape to be transported from a supply roll on one reel to a take-up roll on the other reel,
- b. at least one peripheral support to peripherally engage one of said reels to position same upon initial reception thereof in said assembly, and
- c. centering support means carried by the assembly for relative movement into and out of centrally supporting position in which said one reel is displaced out of peripheral engagement with said peripheral support and is centrally supported for rotation, said centering support means comprising a plunger, and there being actuating means to bodily advance and retract the plunger into and out of reel centrally supporting position, said actuating means comprising a lever operatively connected with the plunger, and structure supporting the lever to pivot in plunger advancing and retracting directions,
- d. and a switch actuated in response to reception of the one reel by the assembly to prevent WRITE circuitry associated with a tape WRITE head defined by the assembly from being inadvertently energized.
1 more element
In a tape transport assembly,
- a. first means to initially receive and peripherally locate a tape reel,
- b. other means to subsequently centrally support the tape reel for rotation,
- c. and belt means engaging tape on the reel when the reel is initially received by said first means and also engaging tape on the reel when the reel is subsequently centrally supported by said other means for rotation.
