The present invention relates to an image reader 3 which reads the reflected light obtained by lightening from underneath a transparency board 6 on which an image original is placed, especially a cover 30 for the image reader 3 for adjusting the bend of the image original. The cover 30 comprise a vacuum pump (not shown) for reducing the air pressure in the space formed by the transparency board 6 and a bend member 48 and an airtight member 50. Therefore the image reader 3 utilizing the cover 30 can correctly read image on both a transparency original and a reflection original, and yet be easy to manipulate when reading the reflection original.

Color separation image signals (Y, M, C, K) are converted into halftone dot image signals (Y.sub.d, M.sub.d, C.sub.d, K.sub.d) by a halftone block circuit (29). Red, green, blue and white beams are obtained from red, green and blue light sources (31R, 31G, 31B) or from a single white light source. These beams are modulated by acousto-optical modulators (32R, 32G, 32B, 35) responsive to the halftone dot image signals (Y.sub.d, M.sub.d, C.sub.d, K.sub.d) and thereafter converged onto a color photosensitive material (23), to produce a halftone dot color image on the color photosensitive material (23).
