Abstract
An image reading apparatus according to the present disclosure includes: a platen glass on which a document is placed; a light source, an image sensor; an image reading unit for optically reading an image of a reading area of the image sensor; a rotatable document cover for covering the platen glass; a cover state detection unit for the document cover; a control unit to detect a sensor output level of the image sensor; and a document size specification unit for the document. The control unit causes the image reading unit to perform a reading operation for specifying the size of the document in the main scanning direction in a state in which the document cover is open, and causes the light source to emit a predetermined light amount in the reading operation, which is larger than the light amount when the document image is read from the document.
