A film screen is perpendicularly slidably mounted on a first guide rail in a microfiche reader. This first guide rail is detachably mounted on a frame which in turn is slidably mounted on a second guide rail perpendicularly with respect to said first guide rail so that the two guide rails form a coordinate support arrangement for selectively displacing the film screen in two mutually perpendicular directions. The second guide rail is mounted on the base of the microfiche reader. The film screen and first guide rail can be easily detached from the frame and replaced by a film screen and first guide rail of different size which is then attached to the frame.

Microfiche reader

A holding frame holds a microfiche. Guide rails mount the holding frame on the microfilm reader housing for movement along two perpendicular coordinate axes for moving selected portions of the microfiche held by the frame into position to be projected. An arresting device arrests the frame in selected positions and includes a stationary clamped structure on the housing and a cooperating releasable clamping structure on the frame. The clamping structure when not released clamps the clamped structure and thereby arrests the frame relative to the housing.
