A recording-material-transporting device includes an attracting part to which a recording material is attracted from below, and a blowing device that blows air from a position higher than the attracting part to an edge of the recording material attracted to the attracting part.

An implementation of an assembly of the present teachings includes a transport roll having a shaft with a tapered surface and an encoder having a coupler that defines a recess and has a tapered surface. During use of the assembly, the tapered surface of the shaft physically contacts the tapered surface of the coupler, and the encoder can be urged toward the transport roll using a spring such as a leaf spring.

A medium transport device includes a transport belt that is disposed in such a manner as to face an image holding unit holding an image and that is capable of moving circularly so as to transport a medium, a first stretching roller that stretches a portion of the transport belt and that is disposed in such a manner as to face the image holding unit, the first stretching roller being configured to transport the medium by nipping the medium between the image holding unit and the transport belt and configured to transfer the image held by the image holding unit onto the medium, a second stretching roller that stretches a portion of the transport belt that is located downstream from the portion of the transport belt stretched by the first stretching roller in a transport direction of the medium, a contact adjusting unit that causes a second end of the first stretching roller in an axial direction of the first stretching roller to swing while a first end of the first stretching roller serves as a fulcrum and adjusts a contact state between the image holding unit and the transport belt in a longitudinal direction of a contact region between the image holding unit and the transport belt, and a position adjusting unit that keeps a distance between the center of the first stretching roller and the center of the second

A medium transport device includes a belt unit and a first support section and a second support section configured to pivotably support the belt unit, wherein the first support section includes a first frame and a second frame that is a flame configured to detach from and attach to the first frame, and configured to pivotably support the belt unit and a direction in the width direction from a the center of a transport belt toward the first support section is an outer direction, the second frame is positioned in the outer direction with respect to the first frame.

An imaging system includes a steering roller and a positioning mechanism. The steering roller extends along a longitudinal direction, and being tiltable about a fulcrum to adjust an alignment position of an endless belt. The positioning mechanism is coupled to the steering roller, to position an adjustable position of the fulcrum of the steering roller, along the longitudinal direction of the steering roller. The positioning mechanism includes a guide that extends along the longitudinal direction of the steering roller, and a protrusion that engages with the guide, and that is located at the adjustable position of the fulcrum.

Included are a feeding shaft configured to hold a printing medium, a first transporting belt, a second transporting belt, a first driving roller on which the first transporting belt is wound, a second driving roller on which the second transporting belt is wound, a first driving unit configured to drive the first driving roller, a second driving unit configured to drive the second driving roller, a winding roller on which the printing medium is wound, a first winding roller bearing, a second winding roller bearing, a first load cell configured to detect a load exerted by the printing medium on the first winding roller bearing, a second load cell configured to detect a load exerted by the printing medium on the second winding roller bearing, and a control unit configured to control the first driving unit and the second driving unit based on detection results of the load cells.

A liquid ejecting device includes a transporting belt configured to transport a medium, a head configured to eject a liquid onto the medium, a first gripping portion configured to grip the first end portion of the transporting belt, and move in the transport direction, and a second gripping portion configured to grip the second end portion of the transporting belt, and move in the transport direction. When the head is positioned outside the transporting belt with respect to the second end portion, the first gripping portion performs a first operation of gripping the transporting belt and moving to a predetermined position, and releasing the gripped transporting belt. When the head is positioned outside the transporting belt with respect to the first end portion, the second gripping portion performs a second operation of gripping the transporting belt and moving to a predetermined position, and releasing the gripped transporting belt.

Provided is technology for effectively removing fiber from a mesh belt. A second web former for conveying a second web containing fiber deposited on a mesh belt 72 having multiple holes 72a has a brush roller 710 with numerous bristles 712 protruding from the surface and disposed in contact with the mesh belt 72. The sectional area of the bristles 712 of the brush roller 710 is smaller than the open area of the holes 72a in the mesh belt 72 so that the distal ends of the bristles 712 can enter the holes 72a.

A belt driving device includes an annular belt member, rotary members, a protrusion, and a removing member. The rotary members extend in parallel and rotate. The belt member is wound around the rotary members. The protrusion protrudes from an inner peripheral surface of the bel member. The protrusion extends along an edge of the belt member. The protrusion and each rotary member are arranged in an extending direction of the rotary member. The removing member includes a plate-shaped portion. The plate-shaped portion is in contact with an outer peripheral surface of the belt member at a location where the removing member faces one of the rotary members with the belt member being interposed therebetween, so as to remove unnecessary matters from the outer peripheral surface of the belt member. The removing member extends to an outside of end portions of the rotary members in the extending direction.

A recording system includes a recording device including a recording unit that performs recording onto a medium, a transporting belt that includes an adhesive layer and transports the medium stuck on the adhesive layer, a drive unit that drives the transporting belt, a control unit that includes a detection unit for detecting a load current flowing in the drive unit and that controls the drive unit. The recording system further includes a peeling device that peels the medium from the transporting belt, and a notification device that provides a notification. The control unit causes the notification device to provide a notification on a time to replace the adhesive layer, based on a detection result of the detection unit.
