Title (EN) IMPROVEMENTS RELATING TO DRAWING APPARATUS
(FR) AMELIORATIONS A UN APPAREIL A DESSINER
Abstract: front page image
(EN)Drawing apparatus has a screen (4, 24) forming one wall of a chamber containing liquid or powder material and a scriber (2, 11, 26). A guide "pen" (3, 13) magnetically attracts the scriber into contact with the screen and as it is moved over the surface the scriber tracks it, making a visible line in the material adhering to the underside of the screen. The surface may have means for producing signals as the pen and scriber traverse, each signal being identifiable with a particular point. If the succession of signals match a stored program, a sound associated with the figure drawn is generated.
(FR)Un appareil a dessiner possede un ecran (4, 24) formant une paroi d'une chambre contenant un liquide ou une poudre et un stylet (2, 11, 26). Une "plume" de guidage (3, 13) attire magnetiquement le stylet en contact avec l'ecran et au fur et a mesure que la plume se deplace sur la surface, le stylet la suit, faisant une ligne visible dans le materiau adherent au-dessous de l'ecran. La surface peut avoir des moyens pour produire des signaux au cours du deplacement de la plume et du stylet, chaque signal identifiant un point particulier. Si la succession de signaux correspond a un programme en memoire, un son associe a la figure dessinee est produit.
