Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
106 words
A device for feeding a data record tape past a transducing station comprising means to defining a tape path, a support including a first bearing: a bearing member mounted in said bearing, a plurality of rotatable tape drive capstans of different diameters, said bearing member including a second bearing eccentric to said first bearing; said capstans being selectively rotatably supported by said second bearing; means for securing said bearing member in different rotated positions in said first bearing whereby to maintain said selected capstans tangentially aligned with said tape path, and means comprising a pinch roller for maintaining said tape in driving engagement with selected capstans.
Claim 2
Independent Claim
106 words
A device for feeding a data record tape past a transducing station comprising means to defining a tape path, a support including a first bearing: a bearing member mounted in said bearing, a plurality of rotatable tape drive capstans of different diameters, said bearing member including a second bearing eccentric to said first bearing; said capstans being selectively rotatably supported by said second bearing; means for securing said bearing member in different rotated positions in said first bearing whereby to maintain said selected capstans tangentially aligned with said tape path, and means comprising a pinch roller for maintaining said tape in driving engagement with selected capstans.
Claim 3
Dependent Claim
39 words
A device according to claim 1 comprising a tape guide member for maintaining said tape in said tape path, said guide member being movable toward and away from tape-guiding position, and said guide member rotatably supporting said pinch roller.
Claim 4
Dependent Claim
14 words
A device according to claim 2 comprising edge-guiding means carried by said tape-guide member.
Claim 5
Dependent Claim
35 words
A device according to claim 2 comprising means for yieldably urging said tape-guide member toward said tape-guiding position whereby to cause said pinch roller to maintain said tape in frictional engagement with said selected capstan.
Claim 6
Dependent Claim
36 words
A device according to claim 2 comprising edge-guiding elements on said guide member, one of said guide elements being movable out of said tape path upon movement of said guide member out of said tape-guiding position.
Claim 7
Dependent Claim
32 words
A device according to claim 5 wherein the other of said guide elements extends in edge-guiding relation to said tape path upon movement of said guide member out of said tape-guiding position.
Claim 8
Dependent Claim
67 words
A device according to claim 1 wherein each of said capstans has a circumferentially extending groove on the outer periphery thereof, and an elastomeric traction ring in said groove, said traction ring being frictionally engageable with a tape extending over said capstan, and said traction ring also being frictionally engageable with a second said capstan extending over said first mentioned capstan whereby to drive said second capstan.
Claim 9
Independent Claim
141 words
A device for feeding a data record tape past a transducing station comprising a support, a tape driving capstan carried by said support and spaced from said transducing station, means for rotating said capstan, a tape-guide member of said support intermediate said transducing station and said capstan, a second tape-guide member intermediate said transducing station and said capstan, means pivotally supporting said second guide member for movement between a tape-guiding position wherein said second guide member extends parallel to first guide member to define a tape path there between and a threading position wherein said second guide member extends at an angle to said first guide member, and a pinch roller carried by said second guide member, said pinch roller being engageable with a portion of said tape extending over said capstan when second guide member is in said tape-guiding position.
Claim 10
Independent Claim
141 words
A device for feeding a data record tape past a transducing station comprising a support, a tape driving capstan carried by said support and spaced from said transducing station, means for rotating said capstan, a tape-guide member of said support intermediate said transducing station and said capstan, a second tape-guide member intermediate said transducing station and said capstan, means pivotally supporting said second guide member for movement between a tape-guiding position wherein said second guide member extends parallel to first guide member to define a tape path there between and a threading position wherein said second guide member extends at an angle to said first guide member, and a pinch roller carried by said second guide member, said pinch roller being engageable with a portion of said tape extending over said capstan when second guide member is in said tape-guiding position.
Claim 11
Dependent Claim
19 words
A device according to claim 8 comprising yieldable means for maintaining said second guide member in said tape-guiding position.
Claim 12
Dependent Claim
28 words
A device according to claim 9 wherein said yieldable means is selectively settable in and out of a position maintaining said second guide member in said tape-guiding position.
Claim 13
Dependent Claim
59 words
A device according to claim 8 comprising edge-guiding elements on saId second guide member, at least one of said edge-guiding elements being movable into cooperative relation with said tape upon movement of said guide member into said tape-guiding position and being movable out of cooperative relation with said tape upon movement of said guide member into said threading position.
