ABSTRACT:
A microform viewer has a case section pivotally mounting a screen, to move from a collapsed position to a viewing position, and slidably receiving a two-part projection section that telescopes into the case section. As the projection section moves into and out of the case section it positively drives the screen between collapsed and display positions. The projection section is made of two mutually separable housings that fit together along the film path so that when the two housings are separated the two pressure plates forming part of the film path are readily accessible.
