Abstract
A microfilm reader-printer having a reader mode for projecting an image of a microfilm onto a screen and a printer mode for printing the image on a copy paper. The screen is provided with indexes indicative of a plurality of sizes of a copy paper. For a copy paper of a size larger than a certain size, the index indicates a smaller size than the size of the copy paper. A lens of variable magnification type is used so that the magnification of the projection lens for the reader mode is made smaller than the magnification for printer mode when a copy paper of a size larger than the certain size is selected. The magnifications for the reader mode and printer mode are made equal to each other when a copy paper of a size smaller than or equal to the certain size is selected.
