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.
Claims7
An image reading apparatus comprising:
- a roller that rotates by being in contact with a document to transport the document along a transport path;
- a reading unit that is disposed at a position in the transport path and reads an image from the document transported by the roller;
- a DC motor that drives the roller;
- and
- a control unit that controls the DC motor,
- wherein the roller is capable of transporting a first document of which a basis weight is a first basis weight and a second document of which a basis weight is a second basis weight larger than the first basis weight, as respective transport targets,
- wherein 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, and
- wherein as the threshold, a first threshold which is applied in a case where the document is the first document and a second threshold which is applied in a case where the document is the second document are set, and the first threshold is less than the second threshold.
