Abstract: An image reading device includes a motor 3, a reading section 7 that reads an image on a medium 5, a first transporting roller 9 that transports the medium in a transport direction F by driving force of the motor and that is provided upstream of the reading section in the transport direction, a second transporting roller 11 that transports the medium in the transport direction by driving force of the motor and that is provided downstream of the reading section in the transport direction, and a measuring section 17, using an encoder sensor 15, configured to measure the rotational position of an encoder scale 13, wherein the encoder scale 13 is provided on a rotation shaft 19 of the second transporting roller 11.

Abstract: A control unit of an image reading device is configured to execute image correction control after performing a first reading operation of reading a medium while transporting the medium in a first direction, and the image correction control includes a second reading operation of reading the medium while transporting the medium in a second direction opposite to the first direction, and a combination process for combining a first area serving as a part of image data acquired through the first reading operation with a second area serving as a part of image data acquired through the second reading operation to acquire image data of one page.

Abstract: A medium transport apparatus includes a controller that determines how many transport roller pairs disposed on a medium transport route are transporting a medium, based on detection information from detectors disposed in relation to respective transport roller pairs. Then, the controller sets a threshold to a larger value as a larger number of transport roller pairs are transporting the medium and sets the threshold to a lower value as a smaller number of transport roller pairs are transporting the medium.
