To enable accurate image reading and concurrently therewith, enable a reading optical system to be varied easily in an apparatus configuration in which first and second read portions are disposed in planes inclined a predetermined angle, the apparatus has an apparatus housing 10, a platen 11 disposed in the apparatus housing to form the first read portion 11a and the second read portion 11b in planes mutually inclined a predetermined angle, a reading carriage 12, 40 disposed to be able to shift to positions between the first read portion and the second read portion, and a light source lamp 15, 41 for applying light to a document sheet on the platen, and a reflecting mirror 16, 42 for guiding the reflected light from the document sheet toward image reading means 13 each mounted on the reading carriage, and is configured so that an angular attitude of the reflecting mirror 16 is deflected by a predetermined angle or deflecting means 46 disposed in the second read portion guides the reflected light to the reflecting mirror 42 when the reading carriage is positioned in the second read portion.
