Abstract
The invention relates to a device for producing x-y coordinate addresses for a picture screen comprising a force-sensitive operating plate (3) influencing force measuring sensors (13a, 13b, 15a, 15b). The coordinates of points on the plate surface (23) are converted, when a force is exerted on these points, by the force measuring sensors (13a, 13b, 15a, 15b) into electrical signals, which correspond to an x-y coordinate address, which is accurately identical to the geographical place of the pressure point of the picture screen. The operating plate (3) has first side edges (17, 17b) arranged approximately parallel and opposite to each other and second side edges (19a, 19b) shifted by about 90.degree. with respect to the first side edges and also arranged parallel and opposite to each other. Auxiliary plates (103, 203) are arranged behind the opeating plate (3) in planes parallel to it. The plates (3, 103, 203) are interconnected by means of resilient edge supports, the resilient edge supports (9a, 9b, 11a, 11b) being obtained from plate to plate longitudinally in the same direction between side edges (17a, 17b, 117a, 117b, 217a, 217b) extending parallel to and over each other and being shifted from plate to plate always alternately by each time about 90.degree. from the first to the second side edges and conversely. The force measuring sensors (13a, 13b and 15a, 15b, respectively) are arranged halfway between the resilient edge supports (9a, 9b and 11a, 11b, reslectively) adjacent the plate edges.
