Arrangement for reading out an optical memory

An arrangement for reading out selected characters from a font of characters stored on a stationary optical memory, comprising a number of light sources each associated with one of said characters for illuminating the same selectively, all of said characters being imaged onto a common location by an optical arrangement comprising one lens and first and second sets of optical elements performing together said imaging onto a common location, the lens imaging the characters into a common image plane, said first set of said optical elements deflecting the different rows of said characters onto said common location, said second set of said optical elements deflecting the different columns of said characters onto said common location each of said first and second sets of optical elements comprising a plurality of individual flat mirrors operating as optical deflecting members for combining the images of the characters at said common location, said arrangement further comprising mounting means for each plurality of deflecting members to maintain said sets of deflecting members in respective predetermined, fixed positions relative to each other on opposite sides of a common plane, and wherein each mirror deflecting member faces said common plane with its reflecting surface, wherein said deflecting optical elements of said first set comprise reflecting elements tilted relative to one another, each element being associated with one row of said characters, and wherein said second set of said deflecting optical elements comprises reflecting elements tilted relative to one another, each element being associated with one column of said characters, so that each mirror element reflects only light from its respectively associated row or column.
