摘要： A sheet transport device includes a pair of movable transport rollers capable of transporting a sheet while holding the sheet and capable of moving in an axial direction crossing a transportation direction; pairs of first transport rollers disposed upstream from the pair of movable transport rollers in the transportation direction while being spaced apart from each other to transport the sheet while holding the sheet; and pairs of transport guides disposed to define sheet transport spaces between the pair of movable transport rollers and the pairs of first transport rollers and between the pairs of first transport rollers. When the pair of movable transport rollers is to be moved in the axial direction, at least one of the pairs of first transport rollers is displaced in the axial direction while holding a portion of the transported sheet.

摘要： A medium transport device include: an inclination corrector including a first inclination correction member and a second inclination correction member disposed away from each other in a width direction of a medium, the first inclination correction member and the second inclination correction member being individually drivable during transport of the medium, the inclination corrector being configured to correct an inclination of the medium relative to a transport direction of the medium by causing a difference in the transport of the medium between the first inclination correction member and the second inclination correction member; and a medium transporter disposed on a downstream side of the inclination corrector in the transport direction and configured to transport the medium, the medium transporter including a pair of medium transport members disposed across the medium in a thickness direction of the medium, the medium transport members being movable between a transport position where the medium transport members nip and transport the medium and a non-nipping position where a nip of the medium is canceled. During correction of the inclination of the medium by the inclination corrector, the medium transporter is moved to the non-nipping position.

摘要： A sheet transporting device includes: plural pairs of transporting rolls that are arranged adjacent to one another in a direction of transport of a sheet; and a component configured to switch individual positions of the plural pairs of transporting rolls between a nipping position and an unnipping position, the component being a single switching component capable of switching a state of nipping by the plural pairs of transporting rolls between a state where all of the plural pairs of transporting rolls are in the nipping position, a state where some of the plural pairs of transporting rolls are in the nipping position while remaining ones of the plural pairs of transporting rolls are in the unnipping position, and a state where all of the plural pairs of transporting rolls are in the unnipping position.

摘要： A sheet transport device includes a pair of movable transport rollers capable of transporting a sheet while holding the sheet and moving in an axial direction crossing a transportation direction; pairs of first transport rollers upstream from the pair of movable transport rollers in the transportation direction while being spaced apart from each other to transport the sheet while holding the sheet; and pairs of transport guides to define sheet transport spaces between the pair of movable transport rollers and the pairs of first transport rollers and between the pairs of first transport rollers. When the pair of movable transport rollers is to be moved in the axial direction, at least one pair of first transport rollers transports the sheet while bending the sheet in the transport space by producing a difference in transport rate within a portion of a section upstream from the pair of movable transport rollers.

摘要： A sheet transport device includes a pair of movable transport rollers capable of transporting a sheet while holding the sheet and capable of moving in an axial direction crossing a transportation direction; pairs of first transport rollers disposed at a distance from each other upstream from the pair of movable transport rollers in the transportation direction to transport the sheet while holding the sheet; and pairs of first transport guides disposed to define sheet transport spaces between the pair of movable transport rollers and the pairs of first transport rollers and between the pairs of first transport rollers. When the pair of movable transport rollers is moved in the axial direction, at least one of the pairs of first transport rollers is displaced in a direction to widen the transport space.
