Space saving, compared to carrying printed material.

Folding, front-projection microfiche viewer.

The Compact Reader folds to one inch thickness, making it easy to carry. The three oval holes allow escaping air, from inside the reader, to blow through the condenser to cool the lamp when being closed. The film gate is centered on the springy pressure plate. The condenser optics in the handle, showing the lamp, lenses and 45° mirror in exploded view. As the screen is opened, the right side of the screen becomes magnified by the Fresnel lens making the screen look rectangular. When closed, the keystoned projection screen can be seen, flat up against the inside of the clear Fresnel lens. When the hinge is pressed through the rubber bellows, the hinge buckles allowing the strut to fold flat. A hinge in the strut is molded in a slight dome to snap open. The bi-stable strut that supports the projection screen is opened by pulling the bellows. The internal strut showing the oil-can dome that snaps open, but collapses when pressed closed. Interior views of the screen and back panel, flat, and open.

adds a slight blue tint to increase image contrast, and to compensate for the warm color of the projection lamp which is under volted to increase lamp life.

skews the optical center line to be perpendicular to the Fresnel lens.acts as a field lens to converge diverging light rays to the viewer’s eyes to brighten the corners,.magnifies the image differentially to make the keystoned image look rectangular,.The mockup to determine the screen angle to give the keystone-shaped screen the appearance of being rectangular when viewed through the Fresnel lens. When the screen is hinged open, and viewed through the clear Fresnel lens, the keystoned image is magnified more on the narrow side, than at the hinge, to create a rectangular-appearing image. The image is front projected on an internal flat screen from an angle which causes the image to be keystoned. This Microfiche Reader is not a rear-projection device as it may appear. C onventional microfiche readers at the time were 110V desk-top units approximately the size and weight of a television of the same screen size. Compact Microfiche Reader wins in space and weight with four or more microfiche, compared to carrying hard-copy.
