  • Image reading apparatus which corrects for positional and angular deviation between the image sensor and the document
    Patent number: 5430550
    Abstract: In an image reader a frame image of a microfilm is projected on a line sensor with a projection lens and read. The projection lens is movable in the main scanning direction by a driving motor. The line sensor is movable in the subscanning direction by a driving motor. The line sensor is moved in the subscanning direction to apply preliminary scanning and detect positional deviation in the main scanning direction of the projected image, and the projection lens is moved in the main scanning direction corresponding to quantity of the positional deviation. When the frame image is inclined, it is rotated relatively to the main scanning direction by a prism to correct the inclination, and the projection lens is moved in the main scanning direction thereafter to correct positional deviation in the same direction.
