ABSTRACT:
A microfiche reader assembly especially suitable for use in a desk drawer of typical size is disclosed herein. This assembly includes a housing, a projection screen, a microfiche support arrangement for supporting a microfiche for movement within a given rectangular operating area and an optical arrangement cooperating with the supported microfiche for projecting an enlarged image of a section of the microfiche on to the screen when the microfiche is in its operating area. While this assembly requires more room than the standard desk drawer allots during use, it is made sufficiently collapsible to fit entirely within the confines of the drawer when not in use so as to allow the drawer to be closed. However, at the same time, the assembly is expandable for use within the drawer when the latter is opened, whereby the assembly does not have to be removed.
