Abstract
An image projection apparatus switchable between a reader mode in which an image is projected on a screen for observation and a printer mode in which an exposure position is scan exposed to the image for obtaining a copied image comprises a support member for supporting two scanning mirrors in a mutually perpendicular manner, and a transport member for supporting and transporting the support member for scanning exposure. An arc-shaped guide portion is provided on the support member or on the transport member, whereby the support member can effect a rotating motion on the transport member, about the crossing point of the two scanning mirrors, and the scanning mirrors effect a rotating motion combined with a linear motion at the scanning exposure.
