IMAGE READING APPARATUS FOR READING IMAGES RECORDED ON FILM

An image reading apparatus is provided with a photoelectric conversion element to be irradiated with the projected light of an original image photographed on a film and is adapted to read out the image. The component lines of the image information in the direction of main scanning are halved by a half mirror and the corresponding halved portions of the image information are simultaneously read out by a first line sensor and a second line sensor. These line sensors are disposed in mutually equivalent positions relative to the half mirror. The direction of motion of the film perpendicular to the direction of main scanning relative to the line sensors is selected between a first direction of motion and a second direction of motion opposite to the first direction of motion. From these line sensors, the image information is produced in the order in which the image information was read out, no matter whichever of the two directions may be selected. These line sensors are disposed on supporting members in such a manner that they may be freely moved in the direction of main scanning and the direction of auxiliary scanning. These line sensors are fastened to the supporting members of their own by means of screw members. When the screw members are rotated, their rotations are not transmitted to the line sensors.
