Abstract

L'invention est relative à un appareil de balayage optoélectronique Selon l'invention, l'appareil comprend un alignement d'éléments photosensibles; un dispositif optique pour former une image lumineuse sur l'alignement; un dispositif de balayage pour balayer successivement tous les éléments pendant une période de longueur A, un dispositif de commande du dispositif de balayage pour balayer l'alignement pendant des périodes successives, et un dispositif d'arrêt qui arrête les signaux de sortie de tous les élements une fois pendant une période de longueur A contenue à l'intérieur d'une période de longueur KA, K étant un nombre entier. L'appareil est applicable à un système de reproduction de fac-similés.The invention relates to an optoelectronic scanning apparatus According to the invention, the apparatus comprises an alignment of photosensitive elements; an optical device for forming a light image on the alignment; a scanning device for successively scanning all the elements during a period of length A, a control device of the scanning device for scanning the alignment during successive periods, and a stop device which stops the output signals of all the elements. elements once during a period of length A contained within a period of length KA, K being an integer. The apparatus is applicable to a facsimile reproduction system.
