In order to enable a sheet to be properly guided to a nip portion in performing folding processing, a sheet processing apparatus for performing folding processing on a sheet is provided with a rotating body pair which nips the sheet by a nip portion to rotate, and thereby draws the sheet to perform folding processing, a folding blade that pushes the sheet to the nip portion of the rotating body pair, and a blade guide member including a guide portion for pushing the sheet to the nip portion when the folding blade pushes the sheet to the nip portion, where the folding blade and blade guide member are relatively shifted so that a distance from a push front edge portion to the guide portion when the folding blade pushes the sheet to the nip portion is longer than a distance from the front edge portion to the guide portion.

A sheet transport device includes: a chain that circulates and moves; a driving unit that circulates and moves the chain; a holding unit that is provided on the chain and holds an end portion of a sheet along a transport direction of the sheet; and a first positioning portion that positions the holding unit on both sides along a direction intersecting both the transport direction of the sheet and a width direction of the sheet while the chain moves along the driving unit.

A recording device includes a pair of transport rollers for transporting a medium, a rotating body provided downstream of the pair of transport rollers in a transport path of the medium and configured to switch between a first state in which the medium being nipped by the pair of transport rollers is passed and a second state in which the the medium being nipped by the pair of transport rollers is not passed, and a recording portion performing recording on the medium by discharging a liquid, in which the pair of transport rollers includes a first toothed roller having a plurality of convex portions configured to make point contact with the medium and nipping the medium by the plurality of the convex portions, and, the pair of transport rollers is arranged only in a central region when the transport path is divided into three in a rotating shaft direction.

A system and method for advancing sticky media through printers includes one or more feed rollers comprised of a grit roller. The grit roller contacts an adhesive side of liner-less label stock removed from a roll or stack for printing. The grit roller works cooperatively with an opposing, counter-rotating roller to remove the label stock from the roll and feed it to a printer.

A contacting member contacts a region of a contacted member to which a liquid composition has been applied. The contacting member has a substrate and a fluororesin fiber layer containing a fluororesin fiber. One side of the fluororesin fiber layer is directly or indirectly fixed to the substrate and another side of the fluororesin fiber layer contacts the contacted member. A ratio X/Y is less than 1.00, wherein X is a presence ratio of the fluororesin fiber in the fluororesin fiber layer on the side which is directly or indirectly fixed to the substrate and Y is a presence ratio of the fluororesin fiber in the fluororesin fiber layer on the other side which contacts the contacted member.

A toothed roller includes: a wheel having teeth on a peripheral surface; and holders that hold n wheels, which satisfy condition 1 and condition 2 described below, such that the n wheels are stacked in an axial direction, n being a natural number of 2 or more. Condition 1 is Pr=Pt/n, where Pr is a tooth pitch of the toothed roller and Pt is a tooth pitch of the wheel. Condition 2 is such that a minimum value of sums of angles each formed by a reference tooth and another reference tooth adjacent thereto in a circumferential direction of one to n wheels is greater than 180 degrees, where one of the teeth is a reference tooth, one of the n wheels is a reference wheel, and wheels having reference teeth near to the reference tooth of the reference wheel are second to nth wheels sequentially.

A contacting member contacts a region of a contacted member to which a liquid composition has been applied. The contacting member contains a substrate, a fluororesin fiber layer, an adhesive layer, and a mixed layer. The fluororesin fiber layer contains a fluororesin fiber and is configured to contact the contacted member. The adhesive layer contains an adhesive member directly or indirectly fixing the fluororesin fiber layer to the substrate. In the mixed layer, the fluororesin fiber in the fluororesin layer and the adhesive member in the adhesive layer are mixed. A thickness of the mixed layer is from 5% or more and 60% or less with respect to a thickness of the fluororesin fiber layer.
