Abstract

A microfilm reader is provided which comprises two casings. The first casing comprises selection means for selecting a micropicture as well as means providing a projection beam for imaging the positioned micropicture through at least one selected orifice in the first casing. The second casing comprises at least one orifice for receiving the projection beam carrying the micropicture information and projection means for displaying the received micropicture information. The two casings can be attached in dual position and by proper positioning of mirrors the projection beam passes through matched orifices of the two casings. The remaining orifices are covered with covers.
