  • Publication number: 20230264487
    Abstract: A printing apparatus includes a printing head; an airflow generating unit; a first flow path that includes a one-side end coupled to the airflow generating unit and an another-side end coupled to a first discharge port and through which the airflow passes; and a peeling unit configured to partially peel the label from the base sheet. When, the label partially peeled from the base sheet by the peeling unit, at least a portion of a peeled portion peeled from the base sheet is at a position not overlapping with the peeling unit in plan view and a non-peeled portion not peeled from the base sheet is in a state of overlapping with the peeling unit in plan view, the first discharge port is disposed at such a position that the airflow outputted from the first discharge port hits the back surface of the peeled portion.

  • Patent number: 11707939
    Abstract: A printing apparatus includes, in a printing apparatus main body, a cover configured to open and close a housing portion configured to house a recording medium, and a first support shaft and a second support shaft configured to rotatably support the cover. The first support shaft is disposed in a position closer to the printing unit than to the housing portion, and the second support shaft is disposed in a position farther from the printing unit than from the housing portion. The cover is configured such that, when displaced from a closed position in a first direction, the cover is rotationally movable around the first support shaft up to a first open position, and that, when the cover is displaced from the closed position in a second direction, the cover is rotationally movable around the second support shaft up to a second open position.

  • Patent number: 11235604
    Abstract: With a cover in a closed position, a first internal gear and a first spur gear do not mesh with each other, and a second internal gear and a second spur gear do not mesh with each other. When the cover rotates by a predetermined angle around a first support shaft from the closed position, the first internal gear and the first spur gear start to mesh with each other. When the cover rotates by a predetermined angle around a second support shaft from the closed position, the second internal gear and the second spur gear start to mesh with each other.

  • Patent number: 9751347
    Abstract: A printer has a platen top unit fastened above the platen unit. The platen top unit is separate from the platen unit, and has first star wheels and second star wheels disposed on parallel horizontal frame members extending perpendicularly to the media conveyance direction above the platen surface. The first star wheels and second star wheels prevent the continuous paper conveyed over the platen surface from lifting away from the platen surface.

  • Patent number: 9566809
    Abstract: The carriage of a line printer has a head unit that supports a printhead, and a carriage frame that supports the head unit movably up and down. When moving the carriage from a standby position to an opposing position, the carriage is moved while the head unit is held at a up position where the gap to the platen unit is a first distance. The head unit is then lowered at the standby position from the up position to a down position where the platen gap is a second distance that is shorter than the first distance.

  • Patent number: 9079429
    Abstract: The invention provides, as an aspect thereof, an inkjet printer that connects a vacuum fan on the printer case side and a vacuum platen on the cover side through a short vacuum path. The platen moves in conjunction with the cover of the roll paper compartment. The platen is a vacuum platen having vacuum regions, suction holes, and a platen-side air path on the platen side, and a vacuum fan and a vacuum duct that connects the vacuum fan to the suction unit of the platen on the printer case side. The vacuum duct is disconnected from the suction unit of the platen when the platen moves in conjunction with the cover, and the length of the vacuum duct can therefore be short, corresponding to the distance between the intake opening of the vacuum fan and the suction unit of the platen when the cover is closed.
