Abstract
Abstract An educational question and answer card-reading apparatus includes a data card which has a multiplicity of questions with a plurality of answers for each on one side of the card. On the other side is a printed circuit with groups of conductive elements arranged to correspond with correct and incorrect answers for each question. The card fits into a card-reading device which has a question selector electrically bridging the conductive elements with conductive rails in the device. The rails are connected in circuit with correct and incorrect answer lamps and with answer-selecting pushbutton switches. Both the answers and printed circuitry may be applied to both sides of the data card. The printed circuit may be concealed or obscured by a layer of plastic, ink or other means so that the pattern of the circuit is not apparent.

Claim 1
Independent Claim
259 words
Educational apparatus for reading a data card having thereon a multiplicity of questions with a plurality of designated answers for each question, and having groups of conductive elements disposed in spaced array in a column longitudinally of one margin of the card, each element in each group corresponding to a designated answer to one of the questions, said apparatus comprising a flat rectangular support for said card; a selector device movable along a marginal portion of said support through a plurality of data-reading positions in slidable engagement with said one margin of the card; a plurality of conductive rails disposed on said marginal portion of the support; contact members carried by said selector device and arranged to contact simultaneously the conductive elements in one of said groups and the rails so that each rail is in direct electric circuit with one of said conductive elements at each of the data reading positions; a plurality of switches on said support connected in circuit with said rails respectively; power supply means carried by said support; and two indicating devices connected in circuit with said power supply means, one of said indicating devices being arranged to provide a correct answer indication when one of said switches which is in circuit with a particular one of the conductive elements in a group thereof is closed, the other of said indicating devices being arranged to provide an incorrect answer indication when any other one of the switches which is in circuit with any of the other conductive elements in said one group is closed.
Claim 2
Dependent Claim
259 words
Educational apparatus for reading a data card having thereon a multiplicity of questions with a plurality of designated answers for each question, and having groups of conductive elements disposed in spaced array in a column longitudinally of one margin of the card, each element in each group corresponding to a designated answer to one of the questions, said apparatus comprising a flat rectangular support for said card; a selector device movable along a marginal portion of said support through a plurality of data-reading positions in slidable engagement with said one margin of the card; a plurality of conductive rails disposed on said marginal portion of the support; contact members carried by said selector device and arranged to contact simultaneously the conductive elements in one of said groups and the rails so that each rail is in direct electric circuit with one of said conductive elements at each of the data reading positions; a plurality of switches on said support connected in circuit with said rails respectively; power supply means carried by said support; and two indicating devices connected in circuit with said power supply means, one of said indicating devices being arranged to provide a correct answer indication when one of said switches which is in circuit with a particular one of the conductive elements in a group thereof is closed, the other of said indicating devices being arranged to provide an incorrect answer indication when any other one of the switches which is in circuit with any of the other conductive elements in said one group is closed.
Claim 3
Dependent Claim
17 words
Apparatus as defined by claim 1, wherein the indicating devices are lamps providing visible correct answer indications.
Claim 4
Dependent Claim
30 words
Apparatus as defined by claim 1, wherein the power supply means comprises at least one battery so that the power supply for said circuit is carried entirely by said support.
Claim 5
Dependent Claim
105 words
Apparatus as defined by claim 1, wherein said data card has two parallel conductive stripes extending longitudinally of said one margin of the card and disposed laterally of opposite ends of said groups of conductive elements, and other conductive stripes connecting the conductive elements in each group thereof to said two stripes, said apparatus further comprising two electrical contacts on said support disposed to contact said two conductive stripes respectively, said two electrical contacts being connected in circuit with the indicating devices respectively so that the same are energized by said power supply means via said two conductive stripes and said two electrical contacts respectively.
Claim 6
Dependent Claim

Apparatus as defined by claim 1, wherein the selector device comprises a lower body slidably engaged with said marginal portion of the support; a pointer bar overlaying said lower body to bear on said one margin of the card; and resilient means in said lower body urging said contact members upwardly toward said pointer bar to slidably engage the conductive elements on said data card, said indicating devices being lamps providing visible correct answer and incorrect answer indications, and wherein said power supply means comprises at least one battery.
Claim 7
Dependent Claim
105 words
Apparatus as defined by claim 5, wherein said data card has two parallel conductive stripes extending longitudinally of said one margin of the card and disposed laterally of opposite ends of said groups of conductive elements, and other conductive stripes connecting the conductive elements in each group thereof to said two stripes; said apparatus further comprising two electrical contacts on said support disposed to contact said two conductive stripes respectively, said two electrical contacts being coNnected in circuit with the indicating devices respectively, so that the same are energized by said power supply means via said two conductive stripes and said two electrical contacts respectively.
Claim 8
Dependent Claim
118 words
