Abstract
An image reading apparatus includes a roller that transports a document; a reading unit that reads an image of the document which is transported; a DC motor that drives the roller; and a control unit that controls the DC motor. The control unit is configured to stop driving of the DC motor in a case where a driving load value obtained when the DC motor is driven exceeds a threshold. A first threshold which is applied in a case of a first document and a second threshold which is applied in a case of a second document of which a basis weight is larger than a first basis weight are set, and the first threshold is less than the second threshold.
