Abstract

Une valise contenant un appareil de communication portatif pour le traitement et la transmission de données se compose d'une valise articulée, dans la coque de laquelle sont prévus, outre une unité centrale, une mémoire, éventuellement avec une unité de disquettes, un clavier et une imprimante, des branchements pour le fonctionnement sur secteur ou sur piles. L'unité d'alimentation en courant comporte un dispositif de commutation sans coupure, le couvercle de la valise renfermant un écran à plasma réglable. Le logement de l'appareil dans la valise comporte un évidement destiné à recevoir le clavier amovible, et en dessous une partie creuse destinée à recevoir un adaptateur-combiné téléphonique amovible d'un coupleur acoustique.
