Abstract
Abstract An automatic tape machine that may be used to teach foreign languages for example and in which a student may listen to a master tape, and then record on a student tap his pronunciation of the lesson and then listen to his recorded lesson before once again hearing the master tape. The machine is designed and constructed such that it operates with a single talk-review lever wherein prior tape machines for teaching have required a number of switches and operations by the student to operate the machine. A number of automatic features are provided including automatic cuing such that while the student is recording on the student tape the master tape backs up one sequence so that it will be prepared to repeat the master tape after the student has completed his recording.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
230 words
A magnetic tape machine for teaching comprising a master tape upon which lessons are recorded, a student tape upon which a student may record his efforts, a master tape deck including a first magnetic head adjacent the master tape and having a supply reel and a takeup reel between which the master tape extends, means for driving said master tape in either direction past the first magnetic head, means for driving said takeup reel, means for driving said supply reel, a second magnetic head adjacent the student tape for recording thereon, a third magnetic head adjacent the student tape for reproducing, means for driving said student tape pass either the second or third magnetic heads, means for sensing when the recorded matter on the student tape has been completed, a control means with a single control connected to said means for driving said master and student tapes and to said sensing means, wherein said control means includes an automatic cuing circuit which detects the audiosignal from a single lesson as the master tape is reversed and which stops the master tape after the master tape has been reversed one lesson. CM,2Netic tape machine according to claim 1 wherein said automatic cuing circuit comprises a master control having a trigger circuit which in a first condition causes said master tape to reverse and in a second position stops said master tape.
Claim 2
Dependent Claim

Claim 8
Dependent Claim
30 words
A magnetic tape machine according to claim 8 comprising means for disabling the means for driving the takeup and supply reels when clear tape is detected by said photoelectric means.
Claim 9
Dependent Claim
32 words
A magnetic tape machine according to claim 1 comprising a student control station and a monitor control station and with the monitor control station including means for overriding said student control station.
Claim 10
Dependent Claim
194 words
A magnetic tape machine for teaching comprising a master tape upon which lessons are recorded, a student tape upon which a student may record his efforts, a master tape deck including a first magnetic head adjacent the master tape and having a supply reel and a takeup reel between which the master tape extends, means for driving said master tape in either direction past the first magnetic head, means for driving said takeup reel, means for driving said supply reel, a second magnetic head adjacent the student tape for recording thereon, a third magnetic head adjacent the student tape for reproducing, means for driving said student tape pass either the second or third magnetic heads, means for sensing when the recorded matter on the student tape has been completed, a control means with a single control connected to said means for driving said master and student tapes and to said sensing means and wherein said control means includes a power control circuit for the means for driving the takeup reel and the supply reel wherein the supply reel is driven faster than normal forward during fast forward and during reversal of the master tape.
Claim 11
Dependent Claim
194 words
