Examples of a media management device for use in a media processing device are described, together with a media processing device for use with a media management device. The media management device supplies a continuous print media to the media processing device, while receiving the media from an external media source. The media management device is arranged to isolate a tension in the continuous print media experienced at the media processing device from a tension in the continuous print media experienced in the external media source.

A label printer includes a print head configured to perform printing on a label sheet, a transporting roller configured to transport the label sheet downstream, a peeling roller configured to transport a backing sheet in a direction different from a travelling direction of a label to peel the label from the backing sheet, and a control unit configured to control rotation of the transporting roller and rotation of the peeling roller, wherein a maximum friction force between the transporting roller and the label sheet are set such that the maximum friction force between the peeling roller and the backing sheet is not greater than a transport force of the peeling roller so as to make a transport error of the label sheet by the transporting roller within an acceptable value.

A layer transfer device configured to transfer at least one layer of a multilayer film onto a toner image includes: a sheet conveying unit; a supply reel; a wind-up reel; a film transfer unit; and a peeling roller disposed between the film transfer unit and the wind-up reel in a conveyance path and configured to peel off the multilayer film from a sheet, and the film transfer unit includes: a first roller provided to contact the sheet; and a second roller provided to contact the multilayer film, and a tangent line of the second roller at a downstream end of a nip part passes between a center of the second roller and a center of the peeling roller, and an angle formed by the tangent line and a film tension portion of the multilayer film tensed between the nip part and the peeling roller is 15 to 37 degrees.

A medium aligning apparatus includes a load tray including a load surface on which a medium discharged from a discharge member that discharges a medium is loaded, a first aligning surface that aligns a plurality of mediums loaded on the load tray by positioning rear ends of the mediums, and a second aligning surface that aligns the mediums by positioning the rear ends of the mediums loaded on the load tray. In the medium aligning apparatus, the first aligning surface and the second aligning surface are switchable, and an angle formed between a wall surface in the discharge tray that receives the mediums discharged from the load tray, the wall surface having the rear ends of the mediums come in contact therewith, and the second aligning surface is smaller than an angle formed between the wall surface and the first aligning surface.

A dispenser for dispensing sheet product is provided including a housing that defines an interior configured to accommodate a source of sheet product and an outlet through which the sheet product is dispensed. The dispenser also includes a first roller that is rotatable and disposed in the housing. A portion of the sheet product is designed to be in contact with the first roller prior to being dispensed through the outlet. The dispenser also includes a knife drum that is rotatable and configured to cooperate with the first roller to dispense the sheet product. The knife drum includes a knife configured to cut the sheet product into individual sheets. The dispenser also includes a spring assembly that may be configured to bias the knife drum toward a predetermined position during rotation of the knife drum.

An elastic roll includes: a roll core; an inner-layer laminate covering an outer-peripheral surface of the roll core parallel to a roll longitudinal direction; a surface-layer elastomer including a tubular portion covering an outer-peripheral surface of the inner-layer laminate, and edge portions connected to the tubular portion, covering both end surfaces of the inner-layer laminate orthogonal to the roll longitudinal direction, and arranged in a manner being in contact with the roll core; and end-portion sealing structural bodies configured to press the edge portions of the surface-layer elastomer against the roll core.

A control device using, as a learning target, a transporting apparatus, a rotation control section which controls at least one of a rotation speed of a first roller and a rotation speed of a second roller, and a position detection section which detects a position of the transport target matter, the control device including a state variable acquisition section which acquires a state variable and a detection result of the position detection section, the state variable being based on information of a state of the transport target matter and information of an environment to which the transport target matter is exposed, and a learning section which learns a control expression for calculating a control value of the rotation control section based on a dataset containing the state variable acquired by the state variable acquisition section and the detection result of the position detection section.

A medium cutting device includes first and second conveying sections and a cutting section. The first conveying section conveys a continuous medium having a perforation that extends in a first direction. The first conveying section conveys the continuous medium in a second direction intersecting the first direction. The second conveying section is spaced from the first conveying section in the second direction, and conveys the continuous medium in the second direction. The cutting section includes a pressing member and a supporting member. The pressing member is movable in the first direction in a gap between the first and second conveying sections. The supporting member movably supports the pressing member in the second direction. The cutting section causes the pressing member to press the continuous medium while causing the pressing member to move in the first direction, thereby cutting the continuous medium at the perforation.

A post-processing apparatus includes a blade, a transfer mechanism, a sheet folding roller pair, a motor, a drive control device, and a control device. The blade presses into the sheet to form a fold line in the sheet. The transfer mechanism moves the blade toward and away from the sheet. The sheet folding roller pair conveys the sheet with the fold line formed by the blade by pinching the sheet at a nip between the sheet folding roller pair. The motor rotatively drives the sheet folding roller pair. The drive control device controls drive of the motor. The control includes a control circuit. When, through the processor executing a control program, the control device controls the transfer mechanism to withdraw from the nip the blade having been pressed into the sheet and the nip by the transfer mechanism, the control device controls the drive control device to stop the motor.

The present invention relates to a pressing cylinder for a material conveying device, in particular for a roller feed, comprising: a piston rod which is configured to engage with a movable component of the material conveying device; a cylinder space which is configured to at least partially guide the piston rod; a piston which is arranged in the cylinder space and which is connected to the piston rod; and a motor; wherein the piston rod comprises a first piston rod element and a second piston rod element which are configured such that a rotational movement of the first piston rod element causes a translational movement of the second piston rod element relative to the piston; wherein the motor is configured to cause the rotational movement of the first piston rod element.
