Provided is a printing apparatus including a printing head, transport rollers (sheet transport rollers) configured to sandwich and transport a medium (label sheet), a medium bending unit (bending member) configured to bend the label sheet to peel off a label from a backing sheet when the label sheet has a configuration in which the label is attached to the backing sheet, and a medium guide (sheet guide) configured to contact with one edge in a width direction of the label sheet to be bent by the bending member. The sheet transport rollers include a biasing mechanism configured to bias the label sheet in a direction intersecting a transport direction of the label sheet and also toward the sheet guide, during transport of the label sheet.

A recording device capable of preventing an occurrence of a transport wrinkle in a transport path is provided. A recording medium transport device includes a driving roller (111) and a driven roller (112) arranged such that a roller axial direction of the driving roller and a roller axial direction of the driven roller are parallel to each other, a recording medium (1) being transported by driving the driving roller (111) with the recording medium (1) held between the driving roller (111) and the driven roller (112), and the driven roller (112) is movably supported from a predetermined position in the roller axial direction, and in a case where the driven roller (112) is separated from the driving roller (111) without holding the recording medium (1) between the driven roller and the driving roller (111), the driven roller (112) moves to the predetermined position in the roller axial direction.

A roll feeder is usable to intermittently feed a coiled material. The roll feeder includes a paired first roll and second roll, a meandering detector, a pressing component, and a controller. The paired first roll and second roll are disposed so as to clamp the coiled material. The paired first roll and second roll are configured to feed the coiled material in a conveyance direction. The meandering detector is configured to detect meandering of the coiled material from a specific conveyance position in a width direction perpendicular to the conveyance direction of the coiled material. The pressing component is configured to press the first roll against the coiled material being conveyed. The controller is configured to control the pressing component so as to correct the meandering based on detection by the meandering detector.

A printer includes a printing unit having a printing head and a platen positioned opposite the printing head, the printing head being configured to print on a print medium that is fed between the printing head and the platen, a ribbon holding shaft configured to hold an ink ribbon that is wound thereon, a ribbon winding shaft configured to wind and collect the ink ribbon supplied from the ribbon holding shaft, and first and second guide shafts provided along a feeding route of the ink ribbon between the ribbon holding shaft and the ribbon winding shaft to apply tension to the ink ribbon. At least one of the first and second guide shafts has a tilt adjuster that applies a twist to the ink ribbon in a width direction of the ink ribbon through said at least one of the first and second guide shafts.

A method of testing a functional unit includes an optical sensor system (28) for detecting an optical signal from at least a part of a moving material web (14), a data processing system (36) for valuating the optical signals, and a display (38) displaying a state of the material web (14) and arranged in a sensitive range (30) of the sensor system (28).

A topping sheet forming method includes: a feeding and division step of feeding a textile original fabric, obtained by weaving longitudinally aligned tire cords into a cord fabric by use of weft yarns, and cutting off the weft yarns in predetermined widthwise positions to divide the textile original fabric into a plurality of narrow textile original fabrics; a calender step of topping, with unvulcanized rubber, at least one surface of one narrow textile original fabric out of the divided narrow textile original fabrics; and a wind-up step of winding up the other narrow textile original fabrics out of the divided narrow textile original fabrics.
