Abstract
An image reading apparatus is provided with a document glass stand on which a document is placed, and a document feeding portion having a platen roller for feeding out the document fed into the reading position of the document glass stand from the reading position and a pressure plate having elasticity and capable of pressing the document placed on the document glass stand against the document glass stand with the platen roller, and openable and closable relative to the document glass stand. A document reading sensor reads the document placed on the document glass stand while being moved below the document glass stand, and reads the document fed into the reading position while being stopped at the reading position. Design is made such that after the document feeding portion is closed and the document has been pressed against the document glass stand by the pressure plate, the platen roller presses the document against the document glass stand.
