Abstract
In an image reading apparatus which uses plural motors to open and close an original conveying apparatus, the original conveying apparatus can smoothly be opened and closed. The image reading apparatus includes an original base plate on which an original is placed; an original conveying apparatus which can be opened and closed with respect to the original base plate, the original conveying apparatus pressing the original against the original base plate while closed; a reading portion which reads an image of the original pressed against the original base plate by the original pressing portion; plural motors which open and close the original conveying apparatus; plural rotary encoders which detect actuation states of the motors; and an opening and closing action controlling portion which controls the motors to match actuation speeds of the plural motors with each other based on the actuation states detected by the rotary encoders.
