  • Publication number: 20230067797
    Abstract: A printing apparatus includes: a roll sheet container that contains a roll sheet around which a recording sheet is wound; a first sheet guide that makes contact with a first surface of the recording sheet; a second sheet guide that makes contact with a second surface of the recording sheet; and a transport roller that transports the recording sheet. The first and second sheet guides are disposed so as to face each other to form a sheet route along which the recording sheet is to pass. The transport roller transports the recording sheet that passed along the sheet route. The second sheet guide includes: a projection that protrudes toward the roll sheet container; and a pushing section that extends from the projection along an outer circumference of the roll sheet and in a direction away from the first sheet guide.

  • Patent number: 11440334
    Abstract: A cutter apparatus is provided that includes a fixed blade and a movable blade positioned facing the fixed blade, and that is configured to cut a medium transported between the fixed blade and the movable blade. The movable blade includes: a guide portion that is driven to reciprocate between a standby position at a distance from the medium and a cutting position, where the movable blade intermeshes with the fixed blade, protrudes further toward the movable blade than a cutting edge of the fixed blade when the movable blade is in the standby position, and is pressed by the movable blade to move in a state of being contact with the fixed blade when the movable blade is in the cutting position; and a biasing member configured to bias the guide portion toward the fixed blade.

  • Patent number: 10086598
    Abstract: A holding unit holds label paper conveyed from a label printer that ejects ink onto the label paper. A peeling unit is disposed to the label paper conveyance path downstream from the holding unit, and peels labels from the liner of the label paper. The peeling unit can move bidirectionally between a start peeling position and an end peeling position. A peeling member folds back only the liner portion of the label paper. A peeling conveyance roller disposed downstream from the peeling member on the label paper conveyance path conveys the label paper. The peeling member moves from the start peeling position to the end peeling position by being pushed by the label paper conveyed by the peeling conveyance roller while the label paper is still held by the holding unit.
