Abstract: A medium clamping device includes a device main unit that includes: a first circularly moving body that has a surface circularly moving and harder than a recording medium; a second circularly moving body that has a surface moving circularly and harder than the recording medium passing between the both surfaces of the two circularly moving bodies; and a load applying section that applies a load to at least one of the first circularly moving body and the second circularly moving body, to sandwich the recording medium by the load with two moving bodies. The medium clamping device further includes: a support section that supports the device main unit and is secured to a fixed body; and an alleviating system that alleviates transmission of a shock from the device main unit to the fixed body and is incorporated in the support section.

Abstract: A medium clamping device includes: a first circularly-moving body having a circumferential surface harder than a recording medium, a longer length in a direction orthogonal to a circularly-moving direction than the recording medium in a first direction; a second circularly-moving body where the recording medium passes between the surfaces of the two circularly-moving bodies in a second direction crossing the first direction; a load applying section applying a load to at least one of the two circularly-moving bodies to clamp the recording medium; a belt member surrounding the surface of at least one of the two circularly-moving bodies, at a place outside an area touching the recording medium when the recording medium passes; and a belt-member-protecting member which is aligned with the belt member in a recording-medium-passing direction, includes a portion closer to a recording-medium-passing path than the belt member to protect the belt member from contacting the recording medium.

Abstract: A sheet-member transport device includes an endless belt that is an endless band member formed by arranging fibers substantially in the form of a mesh, a surface at an outer periphery side of the endless belt being treated with surface processing so that the surface at the outer periphery side has a higher friction coefficient than a friction coefficient of a surface at an inner periphery side of the endless belt; and at least two rotary members, the endless belt being wound around the rotary members, the rotary members being rotated to move the endless belt around the two rotary members.

Abstract: An aspect of the invention is a recording medium transport device including: a rotating body pair including a pair of rotating bodies disposed on a transport path of a recording medium; a pressing mechanism pressing the rotating bodies in a direction to approach each other; elastically deformable first-large-diameter-portions provided at both axial direction outer-sides of a region where the recording medium passes of at least one of the rotating bodies, the first-large-portions having a larger diameter than the outer diameter at the region; and second-large-diameter-portions provided at both axial direction outer-sides of the region of at least one of the rotating bodies, the second-large-diameter-portions having a larger diameter than the outer diameter at the region and having a smaller diameter than the first-large-diameter-portions, and the second-large-diameter-portions forming a gap between peripheral faces of the rotating bodies at the region in a state where the first-large-diameter-portions are elas
