Abstract: A medium transport device includes a first transporter configured to transport a medium by nipping the medium along with rotation, a second transporter configured to transport the medium and disposed on an upstream side of the first transporter in a transport direction of the medium, a first adjuster configured to adjust a position of the medium in a width direction by moving the first transporter and the second transporter in the width direction of the medium with the medium nipped by the first transporter and the second transporter, and a second adjuster configured to adjust a contact pressure of the first transporter for the medium and a contact pressure of the second transporter for the medium based on resistance caused when the medium is moved in the width direction.

Abstract: A sheet transporting device includes: a skew correcting component configured to correct any skew of a sheet by executing speed-gap driving in which first and second transporting components that are arranged at respective positions in a direction intersecting a direction of sheet transport are driven for a predetermined time period with a speed gap between the first and second transporting components; and a changing component configured to change, with reference to a characteristic relevant to sheet transport, a state of the speed-gap driving of the skew correcting component.

Abstract: A sheet transporting device includes first and second position correcting components provided at respective positions in a direction of sheet transport and each being configured to correct a position of a sheet in a direction intersecting the direction of sheet transport by being shifted in the direction intersecting the direction of sheet transport while holding the sheet, and a changing component capable of changing an amount of correction of the position of the sheet individually for the first and second position correcting components.

Abstract: A retracting device includes a housing that is disposed in or on an accommodating unit to be pulled out from an apparatus including a protrusion and that has a groove extending from a first position to a second position and having an opening formed at the first position, the first position corresponding to a position of the protrusion when the accommodating unit moving in a direction in which the accommodating unit is accommodated into the apparatus reaches a predetermined position and the second position corresponding to a position of the protrusion when the accommodating unit is accommodated in the apparatus, and a movable unit that is disposed in the housing and that moves, when the accommodating unit reaches the predetermined position and the protrusion enters the opening, while holding the protrusion to cause the protrusion to move along the groove and with respect to the housing toward the second position.

Abstract: A sheet transport device includes a sheet transport path along which a sheet is transported in one direction, plural abutting portions on which a leading end of the sheet transported along the sheet transport path abuts, the plural abutting portions being arranged in a direction intersecting the one direction, and a moving unit that moves the plural abutting portions and/or moves the sheet in the direction intersecting the one direction so that a preceding corner portion of two corner portions located at the leading end of the transported sheet abuts on any of the plural abutting portions.
