PURPOSE: To provide an enlarging projector by which the depth of field is sufficiently maintained and the video of an object is obtained with a light visual field and the feeling of stereoscopic vision even when projection lateral magnification is large in the case that an object which is deep is enlarged and observed, and which is constituted of an easily produced member.

CONSTITUTION: On an optical path to an image forming position from a projection leans 2, an optical member 3 provided with three-surface reflecting elements is installed. Lenticular lenses are provided to be laid on the back surface of a forward screen and the front surface and the back surface of a backward screen. Then, two sheets of screen 6 whose bus lines are mutually crossed in horizontal and vertical directions and which are closely brought into contact are installed at the image forming position of the lens 2.
