Abstract:
1. A medium transporting device comprising: a transporting path on which a medium is transported; a contacted member that is provided on the transporting path to be movable in a medium width direction orthogonal to a medium transporting direction, and is contacted by an end of the medium transported on the transporting path in the medium width direction; a line-up member on the transporting path that lines up a position of the medium by sending the medium transported on the transporting path to the contacted member to bring the end of the medium in the medium width direction into contact with the contacted member; a displacement amount calculation unit that calculates a misregistration amount of the medium in the medium width direction based on a position of an image recorded on the medium and a reference position of a reference image in an image recording area where the image is recorded on the medium; a contacted position control unit that controls a position of the contacted member by moving the contacted member in a direction of reducing the misregistration amount based on the misregistration amount calculated by the displacement amount calculation unit; and wherein the contacted position control unit is configured to move the contacted member by a magnitude of the misregistration amount and is configured to control the line-up member to line up a position of the medium to contact the contacted member based on the magnitude of the misregistration amount to correct the misregistration amount.
