Abstract
1.didactic and information device, perfected, essentially characterized by the fact of consisting of a base board provided with a multiplicity of openings arranged in rows and columns, and inside which are articulated two keys that subsequently act on the power end of respective articulated levers under the upper surface of the board and to which at its end of resistance are articulated by the lower edge as many other front plates that by gravity are hidden under the upper surface of the board and keep the corresponding levers and key in rest position, so that said plates, when pressing the keys, protrude superiorly from the board by respective slots defined between said keys and the leading edge of the openings of the board, making it possible then each plate to visualize a graphic representation that it is a carrier on its front face and that it constitutes a response to a question that is formulated with a permanently visible graphic representation provided on the outer face of the key that is pressed associated with said plate. 2.didactic and information device, perfected.
