Abstract
Abstract An endless tape cartridge for magnetic recording and reproducing, including first and second hubs rotatably mounted in a cartridge, and an endless tape wound on the first hub. The second hub may be selectively driven to move the endless tape forward fast. The tape is driven with a normal capstan and pinch roller during normal use but the second hub is utilized to move the endless tape forward when the tape is to be moved to a new position in a fast manner. In one modification a pinch roller engages the tape and presses it against the second hub and in a second modification the frictional engagement of the tape with the second hub moves it forward.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
174 words
A cartridge for an endless tape machine having at least one drive shaft, comprising: a spool rotatably mounted in the cartridge; an endless loop of tape wound on the spool; an access opening formed through the cartridge and a portion of said tape available to the access opening so that the tape machine may be operatively associated therewith; a drive capstan of said tape machine engageable with said tape for driving said tape at a first speed in a first mode of operation; a first pinch roll associated with said capstan and in a first operative position of said tape machine engageable to press said tape against said capstan to move said tape for operation with said tape machine; a hub rotatably supported in the cartridge away from said spool and said hub being shaped to be received on said shaft of the tape machine; and said tape engageable with the periphery of said hub so as to be driven at second speed when the tape machine is in a second mode of operation.
Claim 2
Dependent Claim
174 words
A cartridge for an endless tape machine having at least one drive shaft, comprising: a spool rotatably mounted in the cartridge; an endless loop of tape wound on the spool; an access opening formed through the cartridge and a portion of said tape available to the access opening so that the tape machine may be operatively associated therewith; a drive capstan of said tape machine engageable with said tape for driving said tape at a first speed in a first mode of operation; a first pinch roll associated with said capstan and in a first operative position of said tape machine engageable to press said tape against said capstan to move said tape for operation with said tape machine; a hub rotatably supported in the cartridge away from said spool and said hub being shaped to be received on said shaft of the tape machine; and said tape engageable with the periphery of said hub so as to be driven at second speed when the tape machine is in a second mode of operation.
Claim 3
Dependent Claim
35 words
Apparatus according to claim 1 comprising a second pinch roll means movably mounted in said cartridge and in operative association with the hub so as to press said tape against the periphery of said hub.
Claim 4
Dependent Claim
29 words
Apparatus according to claim 2 in which said pinch roll mean includes an arm rotatably supporting a second pinch roll and means pivotally attaching said arm to the cartridge.
Claim 5
Dependent Claim
29 words
Apparatus according to claim 3 in which said pinch roll means further includes spring biasing means attached to said arm to urge the second pinch roll against the hub.
Claim 6
Dependent Claim
26 words
Apparatus according to claim 3 wherein at least a portion of the arm is available through said access opening for operative association with the tape machine.
Claim 7
Dependent Claim
41 words
Apparatus according to claim 1 wherein said hub is formed with an outer ring in frictional engagement with the tape, an inner portion of the hub, and a clutch formed between the outer ring and the inner portion of the hub.
Claim 8
Dependent Claim
39 words
Apparatus according to claim 6 wherein the clutch comprises a tapered opening formed between the ring and the inner portion of the hub and a locking means in the tapered opening for selectively locking the ring and inner portion.
Claim 9
Dependent Claim
13 words
Apparatus according to claim 7 wherein the locking means comprises a round member.
Claim 10
Dependent Claim
12 words
Apparatus according to claim 8 wherein the locking means comprises a sphere.
