ABSTRACT:
An image reading apparatus for reading an image of an original and converting it into an electrical signal, and particularly for reading the image by primary-scanning and secondary-scanning the image by a one-dimensional image sensor. This apparatus has one or two one-dimensional image sensors and is constructed such that the image reading state (for reading by the image sensors) differs when the image is placed in a vertically facing posture at an illuminating position compared to when the image is placed in a horizontally facing posture at the illuminating position, and can properly read the image and reproduce the same when the image is placed in any of these postures.
