Teaching machine
First Claim
1. A teaching machine adapted to pose a question to a user of the machine and to accommodate both a first case wherein a voice signal is audibly reproduced before the entry into the machine of the user'"'"'s answer to the question and a second case wherein a voice signal is audibly reproduced after the entry into the machine of the user'"'"'s answer, said machine comprising:
- a card formed with a single magnetic track, there being a control signal, a correct-answer signal encoding a correct answer to said question, and a voice signal recorded in series on said single magnetic track;
signal reproducing means adapted for movement relative to said card and for sequential reproduction first of said control signal and then of the remaining ones of said recorded signal and then of the remaining ones of said recorded signals in response to said relative movement, at least said control signal being formed of a plurality of bits capable of distinguishing at least said first and second cases;
entry means by which a user of the machine can enter into said machine a test answer to said question;
first memory means responsive to said correct-answer signal as reproduced by said signal-reproducing means for storing said correct answer;
second memory means responive to said entry means for storing said test answer;
comparator means jointly responsive to said first and second memory means for making a comparison between said correct answer and said test answer and for producing an output signal in accordance with said comparison;
signaling means responsive to said comparator output signal for indicating to said user whether said test answer is correct; and
audio means controlled by said control signal so that said audio means audibly reproduces said voice signal before making said comparison in said first case and after making said comparison in said second case.

Abstract
A teaching machine is used with a card to pose a question to a user of the machine and to accommodate both a first case wherein a voice signal is audibly reproduced before the user enters his answer to the question into the machine and a second case wherein a voice signal is audibly reproduced after the user enters his answer into the machine. The machine includes a signal reproducer that cooperates with a card upon which a control signal, a correct-answer signal encoding a correct answer to the question and a voice signal are recorded and that reproduces the recorded signals from the card. A user of the machine enters a test answer to the question into the machine via a keyboard. A first memory responds to the correct-answer signal as reproduced by the signal reproducer for storing the correct answer, and a second memory responds to the keyboard for storing the test answer. A comparator responds jointly to the first and second memories for comparing the correct answer and the test answer and producing an output signal in accordance with the comparison. Lamps responsive to the comparator output signal indicate whether or not the test answer is correct. An audio channel jointly responsive to the control signal and the voice signal as reproduced by the signal reproducer audibly reproduces the voice signal before making the comparison in the first case and after making the comparison in the second case.
