    摘要: An electron-beam information exchange apparatus adapted to effect information exchange in incoming light signals and outgoing light signals by utilizing electron beams. The apparatus has a plurality of electron beam generating means for generating electron beams according to the incoming light signals; a plurality of electron beam deflecting means for independently deflecting individual electron beams emitted from the electron beam generating means; and a plurality of electron beam detecting means for reproducing information from the thus-deflected electron beams to generate the outgoing light beams. The electron beam detecting means controls the electron beams so that each of the electron beams is made incident upon a desired one of said electron beam detecting means. Also, the electron beam generating means are semiconductor devices for generating electron beams.
