Abstract

L'invention concerne les claviers d'entrée de données. Le clavier du type à panneau sensible au toucher, contient une plaque de couverture 25 sous la forme d'une structure feuilletée comportant une diapositive de film photographique couleur où apparaissent les positions de touches 26 avec les indications appropriées 27. Cette diapositive est recouverte d'un film plastique transparent. Derrière la diapositive 25, une couche diélectrique 28 fournit le fond blanc nécessaire pour obtenir des parties blanches sur la plaque de couverture. Le reste du clavier se compose de deux cartes de circuits imprimés 29 et 30 qui contiennent les commutateurs de touches et les circuits électriques annexes. Utilisable pour l'entrée de données dans les calculateurs.The invention relates to data entry keyboards. The touch sensitive panel type keypad contains a cover plate 25 in the form of a laminated structure having a slide of color photographic film where the key positions 26 appear with the appropriate markings 27. This slide is covered with transparent plastic film. Behind slide 25, a dielectric layer 28 provides the white background necessary to obtain white portions on the cover plate. The rest of the keyboard consists of two printed circuit boards 29 and 30 which contain the key switches and the ancillary electrical circuits. Usable for data entry into calculators.
