Abstract
Abstract A branched teaching machine that selects frames for presentation to the student in accordance with individualistic responses is connected to the remote control of a rotatable slide projector and causes the slide projector to move either forward or reverse in step with its search for the frame to be selected and presented. As the frame is presented, a slide in the slide projector may also be shown. As a primary feature of this invention, a printed paper record, attaChed to the rotatable tray, and giving a frame-by-frame resume of the teaching machine''s branched programs, is electrically marked at all frames viewed by the student. Hence, a permanent, readily readable record is provided which can be used by a teacher to diagnose the path the student took in going through the teaching machine program.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
77 words
For use with a teaching device, recording apparatus comprising a movable member, means for moving said member discrete steps in forward and reverse directions and adapted to be activated by electrical signals from the teaching device, means for attaching record material to said member, and means for marking the record material with a high-voltage electrical charge whereby the record material is marked when said member is moved to a specified position as determined by the teaching device.
Claim 2
Dependent Claim
77 words
For use with a teaching device, recording apparatus comprising a movable member, means for moving said member discrete steps in forward and reverse directions and adapted to be activated by electrical signals from the teaching device, means for attaching record material to said member, and means for marking the record material with a high-voltage electrical charge whereby the record material is marked when said member is moved to a specified position as determined by the teaching device.
Claim 3
Dependent Claim
24 words
The recording apparatus as recited in claim 1 wherein said recording apparatus includes a slide projector having a movable tray defining said movable member.
Claim 4
Dependent Claim
17 words
The recording apparatus as recited in claim 2 wherein said tray is circular and is rotatably movable.
Claim 5
Dependent Claim
57 words
The combination comprising a slide projector having a movable tray for receiving slides, control means adapted to receive electrical signals from a controlling source to selectively move said tray, means for attaching record material to said tray and means adapted to receive the electrical signals from the controlling source to mark the record material in responsE thereto.
Claim 6
Dependent Claim
57 words
The combination comprising a slide projector having a movable tray for receiving slides, control means adapted to receive electrical signals from a controlling source to selectively move said tray, means for attaching record material to said tray and means adapted to receive the electrical signals from the controlling source to mark the record material in responsE thereto.
Claim 7
Dependent Claim
94 words
The combination comprising a teaching device including means for selectively moving a film to predetermined frames, and signal generating means for providing electrical signals corresponding to operation of said film moving means; and recording apparatus including a movable member, means for attaching record material to said movable member, control means connected with said signal-generating means to drive said movable member in response to said electrical signals, and marking means connected with said signal generating means to mark said record material at specified positions corresponding to said predetermined frames in response to said electrical signals.
Claim 8
Dependent Claim
94 words
The combination comprising a teaching device including means for selectively moving a film to predetermined frames, and signal generating means for providing electrical signals corresponding to operation of said film moving means; and recording apparatus including a movable member, means for attaching record material to said movable member, control means connected with said signal-generating means to drive said movable member in response to said electrical signals, and marking means connected with said signal generating means to mark said record material at specified positions corresponding to said predetermined frames in response to said electrical signals.
Claim 9
Dependent Claim
80 words
The combination as recited in claim 5 wherein said electrical signals include first signals representing the direction of movement of said film and second signals representing the status of said film as being moving or stationary, said control means receives said first signals to control the direction of movement of said movable member in the same direction as said film, and said marking means receives said second signals to mark said record material when the movement of said film stops.
Claim 10
Dependent Claim
34 words
The combination as recited in claim 6 wherein said marking means includes a timing circuit responsive to said second signals to mark said record material only once after the movement of said film stops.
Claim 11
Dependent Claim
28 words
The combination as recited in claim 7 wherein said marking means includes means responsive to said timing circuit for providing a high-voltage spark to mark said record material.
Claim 12
Dependent Claim
92 words
For use with a teaching device having a film selectively movable to predetermined frames and providing electrical signals corresponding to movement of the film, recording apparatus comprising a movable member, means for attaching record material to said movable member, control means for receiving the electrical signals from the teaching device to drive said movable member in response to the electrical signals, and marking means for receiving the electrical signals from the teaching device to mark the record material at specified positions corresponding to the predetermined frames in response to the electrical signals.
Claim 13
Dependent Claim
92 words
For use with a teaching device having a film selectively movable to predetermined frames and providing electrical signals corresponding to movement of the film, recording apparatus comprising a movable member, means for attaching record material to said movable member, control means for receiving the electrical signals from the teaching device to drive said movable member in response to the electrical signals, and marking means for receiving the electrical signals from the teaching device to mark the record material at specified positions corresponding to the predetermined frames in response to the electrical signals.
Claim 14
Dependent Claim
112 words
The recording apparatus as recited in claim 9 wherein the electrical signals provided by the teaching device include first signals corresponding to the direction of movement of the film and second signals representing the status of the film as being moving or stationary, said control means being adapted to receive the first signals from the teaching device and including means for driving said movable member in a direction corresponding to the direction of movement of the film in the teaching device, and said marking means being adapted to receive the second signals and responsive thereto to mark the record material in response to the second signals representing the film as being stationary.
Claim 15
Dependent Claim
35 words
The recording apparatus as recited in claim 10 wherein said marking means includes a timing circuit responsive to the second signal to mark the record material only once after the movement of the film stops.
Claim 16
Dependent Claim
29 words
The recording apparatus as recited in claim 11 wherein said marking means includes means responsive to said timing circuit for providing a high-voltage spark to mark the record material.
