Abstract
Abstract Educational apparatus with a circuitry board provided to receive a program pannel having a problem or question section and response or answer section to permit the operator to first, through contact engaging means, select a question in the question section to be answered, and, secondly, seek proper selection of an answer through contact engaging means in the answer section, the correct response being indicated by signal means, such as, in the form of a light or bell. Selective switch means is provided in the circuitry board operative to indicate to the operator at any time desired the proper and correct response to the question selected through the signal means.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
164 words
An educational apparatus comprising a base, an assignment circuit matrix included in said base, a plurality of spaced question contacts arranged in one portion of said base and a plurality of spaced answer contacts arranged in another area of said base, signal means individually connected to each of said question contacts to the Other side of said circuit matrix, a pair of contact engaging means for connection to one of said question and answer contacts, respectively, wherein said signal means is activated when said engaging means are connected to proper question and answer contacts, selective switch means connecting said contact engaging means to direct current power source, a diode connected between each signal means and said answer contact with their other end connected to said selective switch means, said selective switch means operative to reverse the polarity of said power source to operate selective of said signal means dependent upon connection of one of said contact engaging means in one of said question contacts.
Claim 2
Dependent Claim
164 words
An educational apparatus comprising a base, an assignment circuit matrix included in said base, a plurality of spaced question contacts arranged in one portion of said base and a plurality of spaced answer contacts arranged in another area of said base, signal means individually connected to each of said question contacts to the Other side of said circuit matrix, a pair of contact engaging means for connection to one of said question and answer contacts, respectively, wherein said signal means is activated when said engaging means are connected to proper question and answer contacts, selective switch means connecting said contact engaging means to direct current power source, a diode connected between each signal means and said answer contact with their other end connected to said selective switch means, said selective switch means operative to reverse the polarity of said power source to operate selective of said signal means dependent upon connection of one of said contact engaging means in one of said question contacts.
