Abstract
Disclosed is a reader-printer capable of being changed over between a reader mode in which the light image of an original is projected onto a screen and a printer mode in which the light image of the original is projected onto a photosensitive medium. The reader-printer has first optical means for forming a first optical path for projecting the light image onto the screen and second optical means for forming a second optical path for projecting the light image onto the photosensitive medium. The second optical means includes a first mirror and a second mirror. The first mirror is movable so that it is positioned outside the first optical path during the reader mode and is positioned in the first optical path during the printer mode. The second mirror is movable with the first mirror. When the first mirror is being moved between a first position and a second position, the light from the original is detected by light detecting means, and when the first mirror is positioned in the first optical path, the light image is reflected by the first mirror and then reflected and guided to the photosensitive medium by the second mirror.
