Abstract

Pour faciliter le nettoyage et améliorer l'hygiène de ce clavier utilisé par exemple dans une balance de charcuterie ou de poissonnerie, chaque touche 15 ou 16 est réunie au poussoir 9 ou 10 correspondant avec interposition d'une membrane souple 11. Le poussoir porte une plaque d'étanchéité 12 ou 13 dont la surface est au moins égale à celle de la face inférieure de la touche. De cette façon, les corps étrangers, graisses, liquides, etc. ne peuvent pas s'infiltrer entre la membrane et chaque touche de sorte que, après avoir enlevé la plaque de protection 18, on peut nettoyer facilement et totalement la membrane et les touches. De plus, chaque touche étant guidée par son poussoir, auquel elle est assemblée par exemple par enclenchement, elle ne risque pas de se coincer dans l'ouverture 19 ou 20 de la plaque de protection 18.To facilitate cleaning and improve the hygiene of this keyboard used for example in a delicatessen or fish scale, each key 15 or 16 is joined to the corresponding pusher 9 or 10 with the interposition of a flexible membrane 11. The pusher carries a sealing plate 12 or 13 whose surface is at least equal to that of the underside of the key. In this way, foreign bodies, fats, liquids, etc. cannot infiltrate between the membrane and each button so that, after removing the protective plate 18, the membrane and the buttons can be easily and completely cleaned. In addition, each key being guided by its pusher, to which it is assembled, for example by engagement, it does not risk being trapped in the opening 19 or 20 of the protective plate 18.
