Abstract
A scanner includes: a first transport roller pair that transports a material; a reader that reads the material; a second transport roller pair that transports the material; a transport motor; and a pressing section. The transport motor 50 rotates both the rollers of the first transport roller pair and both the rollers of the second transport roller pair. The pressing section can vary a first pressing force generated in the first transport roller pair and a second pressing force generated in the second transport roller pair. The pressing section varies the second pressing force in such a way that the second pressing force when the first transport roller pair transports the material but the second transport roller pair does not transport the material becomes lower than the second pressing force when neither the first transport roller pair nor the second transport roller pair transports the material.
