Abstract
Abstract A tape cassette playback machine with a playback head utilizes a forward drive pinion, a pressure roller and capstan to drive audio tape in a cassette in forward direction past the playback head to cause the intelligence on the audio tape to be played out by the playback machine. It utilizes a reverse drive pinion to rewind the audio tape within the cassette. These drive pinions mesh with forward and reverse cassette drive sprockets, respectively, which are integral with the forward and reverse tape takeup reels within the cassette. The outer case of a cassette phrase retriever is situated over the tape cassette in the playback machine, and has a rotatably mounted reverse drive spider or pinion extending downwardly from it into driving relationship with respect to the cassette reverse drive sprocket. Manually operable mechanism is provided in the retriever for selectively driving the reverse drive spider in rewind direction through any one of several preselected angular distances thus to cause the tape within the cassette to back up past the playback head in the playback machine for any one of a plurality of preselected linear distances. This manually operable mechanism is disengaged from the reverse drive spider when not in operation, thus to let the spider turn freely with the cassette reverse drive sprocket during normal forward or rewind movement of the tape through the playback machine.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
327 words
A tape cassette phrase retriever for use with a tape cassette playback machine and a tape cassette in which tape cassette, tape containing intelligence is entrained on a forward tape takeup reel and a reverse tape takeup reel, the reverse tape takeup reel having sprocket means which, when rotated in a first direction, will cause the tape to be wound from the forward tape takeup reel onto the reverse tape takeup reel and in which the tape cassette playback machine has means for receiving said cassette, means for driving said tape from said reverse tape takeup reel towards forward tape takeup reel, means for playing out the intelligence on said tape as it moves from said reverse takeup reel to said forward takeup reel, and means for stopping said tape drive means when a phrase on said tape to be repeated has just been played out by said machine; said tape cassette phrase retriever including: A. a case having an outer face plate, and means cooperating with said cassette playback machine and cassette for fixedly positioning said case with respect to the cassette and playback machine; B. pinion means rotatably mounted with respect to said case and extending outwardly therefrom in position to be in operative driving relationship to said cassette reverse reel sprocket means so that rotation of said pinion means in a first direction will cause said sprocket means to rotate in said first direction to cause tape to be wound from said forward reel onto said reverse reel; C. manually operable means mounted with respect to said retriever case for positively rotating said retriever pinion means in said first direction; and D. means to limit the amount of movement of said manually operable means to the end that precisely the proper length of tape will be retrieved onto the reverse tape takeup reel to cause a phrase which is to be repeated to be played back beginning specifically with the start of such phrase.
Claim 2
Dependent Claim
327 words
A tape cassette phrase retriever for use with a tape cassette playback machine and a tape cassette in which tape cassette, tape containing intelligence is entrained on a forward tape takeup reel and a reverse tape takeup reel, the reverse tape takeup reel having sprocket means which, when rotated in a first direction, will cause the tape to be wound from the forward tape takeup reel onto the reverse tape takeup reel and in which the tape cassette playback machine has means for receiving said cassette, means for driving said tape from said reverse tape takeup reel towards forward tape takeup reel, means for playing out the intelligence on said tape as it moves from said reverse takeup reel to said forward takeup reel, and means for stopping said tape drive means when a phrase on said tape to be repeated has just been played out by said machine; said tape cassette phrase retriever including: A. a case having an outer face plate, and means cooperating with said cassette playback machine and cassette for fixedly positioning said case with respect to the cassette and playback machine; B. pinion means rotatably mounted with respect to said case and extending outwardly therefrom in position to be in operative driving relationship to said cassette reverse reel sprocket means so that rotation of said pinion means in a first direction will cause said sprocket means to rotate in said first direction to cause tape to be wound from said forward reel onto said reverse reel; C. manually operable means mounted with respect to said retriever case for positively rotating said retriever pinion means in said first direction; and D. means to limit the amount of movement of said manually operable means to the end that precisely the proper length of tape will be retrieved onto the reverse tape takeup reel to cause a phrase which is to be repeated to be played back beginning specifically with the start of such phrase.
Claim 3
Dependent Claim
70 words
The tape cassette phrase retriever of Claim 1 wherein said means to limit the amount of movement of said manually operable means includes: A. a plurality of finger pieces mounted in said case through the case face plate; and B. separate means associated with each of said finger pieces to separately limit the amount of movement of said manually operable means responsive to the positioning of its associated finger piece.
Claim 4
Dependent Claim
176 words
The tape cassette phrase retriever of claim 1 wherein said retriever pinion means includes a pinion shaft and a pinion mounted on said pinion shaft and positioned to be in operational relationship with respect to said reverse tape takeup reel sprocket means when said retriever is fixedly positioned with respect to said cassette and playback machine, said pinion being rotatably mounted with respect to said case; A. there being a pinion drive wheel mounted inside of said case on the same pinion shaft to rotate with the pinion; B. a wobble bracket pivotally mounted inside of said case; C. a fraction drive wheel rotatably mounted on said wobble bracket on an axis parallel to and spaced from the axis of the pivotal mounting of the wobble bracket with respect to the case; and D. said manually operable means for driving said retriever sprocket means including means for pivoting said wobble bracket to bring said friction drive wheel into driving relationship with repsect to said sprocket drive wheel and means to positively rotate said friction drive wheel.
