Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 314 words
An electrically operated self-examination device comprising A. an electrical circuit including a metal electrical conducting panel, a battery mounted on one side of said panel and electrically connected thereto, an electrical responsive lamp connected to one pole of said battery, and a probing lead connected to the other pole of said battery whereby contact of said probing lead with said panel closes the circuit and activates said lamp. B. a non-conducting plastic sheet laminated to the other side of said panel and having a plurality of apertures through which said circuit may be closed by contacting said probing lead to said panel. C. a question card adapted to be in flat registry against said non-conducting sheet, said card having printed questions on the surface opposed to said sheet, each question having multiple choice answers and an opening associated with each answer, said answer card openings having been positioned so that correct answer openings register with plastic sheet apertures whereby said lamp will be lit when said probe is placed through a correct answer aperture, and D. a case sized to hold in snug registry said conducting panel and said card lying against said non-conducting sheet with said card facing a front opening side of said case, said conducting panel being spaced from the rear wall of said case a sufficient distance to clear said battery and indicator and further provide space for storage of a plurality of said answer cards, said case being provided with a pivotal wing panel on each side of said front opening that overlap on closing to form a front wall to said case and provide two display panels when open, said card and said conducting panel having an opening in alignment with said lamp for observation thereof from the front of said case, and said rear wall having a pivotal support member to hold said case in standing position.
