The image reading apparatus of this invention reads a desired image out of an original document with a CCD 1, edits a desired area of the thus read image with an edit processing part 4, and causes the edited area to be copied without being subjected to negative-positive inversion. The edit processing part 4 sets an optimum density severally for an area requiring negative-positive inversion and for an area not requiring negative-positive inversion. Thus, necessary information existing in the area of image and the area outside the image can be printed out without causing the formation of a completely black frame and density of the print can be optimized without discrimination between these areas.

Image reading apparatus for reading an image containing both a negative

An image reading device by which a plurality of images recorded and set in a prescribed posture on an original document are scanned by one scanning motion, changed in layout and then outputted in the changed order. The image reading apparatus includes an image reading means for reading an original document including a plurality of images and space, a distinguishing means for distinguishing the images from the space, a memory means for memorizing only the image data and an output means for outputting memorized image data in a different order.

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.
