Abstract: PROBLEM TO BE SOLVED: To minimize leakage of a light source at the time of reading a thick original such as a book and a magazine by providing an original pressing plate attaching mechanism which supports an original pressing plate attached to be freely opened and closed, and to make the original pressing plate vertically movable with respect to a device main body. SOLUTION: This image reader is provided with the original pressing plate 103 for allowing the placed original 102 to closely contact to an original platen 101, an original pressing plate shaft 104 for opening/closing the original pressing plate 103 and a hole 107 for making the original pressing plate shaft 104 vertically movable. When the original 102 is thick, the original pressing plate shaft 104 is moved upward in the hole 107 and the original pressing plate 103 is closed. Therefore, the original pressing plate 103 can be closed in parallel with the original 102, so that the original 102 can be brought into close contact with the original platen 101 in parallel, and the original is prevented from being deviated.  Since the original pressing plate 103 can be closed in parallel with the original 102, the leakage from the light source at the time of reading the original 102 can be minimized.
