Abstract

Système de boutons poussoirs en lignes et en colonnes dont le changement de position coupe deux faisceaux lumineux. Le corps 1 comprend des canaux 2, 3 parallèles à deux axes de coordonnées, les lignes 3 étant dans un plan et les colonnes 2 dans un plan parallèle. A une extrémité de chaque canal se trouve une source lumineuse 4 et, à l'autre extrémité, un détecteur 5. A chaque croisement se trouve un bouton poussoir 6 coupant, quand on l'actionne, la ligne et la colonne qui lui correspond.System of push buttons in rows and columns whose change of position cuts two light beams. The body 1 comprises channels 2, 3 parallel to two coordinate axes, the lines 3 being in a plane and the columns 2 in a parallel plane. At one end of each channel is a light source 4 and, at the other end, a detector 5. At each crossing is a push button 6 cutting, when actuated, the row and column that corresponds to it.
