The present disclosure relates to the technical field of printing, and provides a digital printing press. The digital printing press includes a frame, and an unwinder, a driver, an inkjet printer, a curer and a winder that are arranged on the frame, where the driver drives a substrate to move from the unwinder to the winder along a substrate path, the inkjet printer and the curer are arranged above a printing segment of the substrate path, the printing segment of the substrate path is in the shape of an arch, and the arch bends toward the inkjet printer and the curer. The UV light from the curer can be reflected by the substrate to a position other than the inkjet printer as a result of the arched printing segment. UV light is prevented from entering the inkjet printer's nozzle, extending the inkjet printer's service life.

A printer includes a first guide disposed downstream of a platen in a sub-scanning direction to guide movement of a recording medium, a second guide disposed below the first guide and downstream of the first guide in the sub-scanning direction to guide movement of the recording medium, and a dryer facing the first guide and the second guide to send air toward the recording medium. The dryer includes a body case including an outlet port that is open toward the second guide, a fan to send air toward the recording medium through the outlet port, and a heater to heat air sent by the fan. The first guide has a thermal conductivity higher than a thermal conductivity of the second guide.

The printing device comprises: a print head for printing on a tape; a platen roller for conveying the tape by rotation with the tape held between the print head and the platen roller; a supporter for rotatably supporting the platen roller; and a cam including a first guide for releasing pressing of the platen roller against the print head and a second guide for pressing the platen roller against the print head.

A recording apparatus includes a recording unit configured to perform recording on a recording medium that is a long medium, a supporting part disposed opposite to the recording unit and configured to support the recording medium, a cutting part configured to cut the long medium into a single sheet medium, a guide member configured to guide the recording medium, a winding unit configured to wind up the long medium, and a medium housing unit configured to be detachable and house the single sheet medium. The guide member is displaceable to a first supporting position in which the guide member supports the recording medium being conveyed to the medium housing unit and a second supporting position in which the guide member supports the long medium being conveyed to the winding unit, the second supporting position being located above the first supporting position.

A cleaning roller to be brought into contact with a medium includes a rotary shaft having a first end portion and a second end portion, and a sticky roller attached to the rotary shaft. A cleaning roller holder includes a first bearing portion configured to restrict a movement range of the first end portion and a second bearing portion configured to restrict a movement range of the second end portion. In a state where the first end portion is disposed at the first bearing portion and the second end portion is disposed at the second bearing portion, the cleaning roller holder positions the cleaning roller in a detachable manner. The center of gravity of the cleaning roller is shifted from the center of the cleaning roller in the longitudinal direction toward the first end portion, and is in a range where the sticky roller exists in the longitudinal direction.

A printing apparatus includes a transport unit configured to transport a medium in a transport direction, a printing unit configured to perform printing on the medium transported by the transport unit and supported by a platen, a downstream guiding unit as a medium guiding unit having a guide surface for guiding the medium downstream in the transport direction from the platen, a heating unit disposed at a position facing the guide surface, and configured to heat the medium, and a spacer provided above the guide surface, and configured to separate the medium from the guide surface.

A housing is provided with a sheet ejection port for discharging sheet that passed through a printing unit upward. A cutting unit is arranged between the printing unit and the sheet ejection port and cuts the sheet by either a method of cutting the sheet in the entire width direction or a method of leaving the central portion of the sheet in the width direction. First protrusions and second protrusions protruding from the inner periphery of the sheet ejection port are provided at a plurality of locations along the width direction of the sheet. The first protrusion faces a first surface of the sheet and the second protrusion faces a second surface, which is the back surface of the first surface of the sheet. The first protrusion and the second protrusion are provided at positions deviated from each other in the sheet width direction and bend the sheet in an undulating shape in the width direction therebetween. Further, protrusion height of at least one of the first protrusions and the second protrusions in the central portion in the width direction of the sheet is lower than protrusion heights of the first protrusions and the second protrusions in other regions.

An inkjet recording apparatus includes a sheet conveyance portion, a pair of registration rollers, a recording portion, a plate portion, a suction roller, and an exhaust portion. The exhaust portion is disposed over an area from upstream of the recording portion to upstream of the pair of registration rollers with respect to the sheet conveyance direction and sucks air from above the conveyance belt and the plate portion in the direction away from the conveyance belt. The exhaust portion includes an exhaust hood and an exhaust fan. The exhaust fan guides the air in the exhaust hood through an air inlet into a recording potion housing and then passes the air through an exhaust outlet to discharge it via an air flow passage.

A printer includes a curved path through which a medium is transported toward a line head, a transport roller pair provided in the curved path, pinching the medium by a driving roller and a driven roller at a pinching position, and transporting the medium, a gate portion having a contact surface configured to switch between a contact position located upstream of the pinching position in a transport direction in the curved path and a retreat position at which the contact surface does not contact with the medium, and a guide portion guiding a tip of the transported medium to the contact surface located at the contact position.

A medium-cutting device includes a medium-conveyance section to convey a medium in a medium-conveyance direction, a cutter to cut the medium conveyed by the medium-conveyance section, and a pushing part to push up a piece of the medium that is cut from the medium with the cutter.
