  • Patent number: 10870550
    Abstract: In a printing apparatus, the ends of print media fed continuously can be prevented from colliding with each other. The printing apparatus includes a printing unit configured to perform a print operation, a detecting unit configured to detect a conveyance abnormality, a conveying unit configured to convey a preceding print medium and a succeeding print medium, a conveying path having a first area including a curved portion at which a conveying direction of the print medium is curved and a second area upstream of the first area, and an opening unit capable of opening the first area of the conveying path. In a case in which a leading edge of the succeeding print medium is located in the second area at the time of the detecting unit detecting conveyance abnormality of the preceding print medium, the conveying unit conveys the succeeding print medium so that the leading edge of the succeeding print medium reaches the first area.

  • Patent number: 10857819
    Abstract: A printing apparatus can be downsized while degradation in the print quality can be suppressed. To perform skew correction on a second print medium on which printing is to be performed subsequent to a first print medium, a first conveying unit disposed upstream of the printing position where the printing unit performs printing on the print medium is stopped. Then, driving and stopping of third conveying unit disposed downstream of a second conveying unit is controlled, depending on whether the first print medium after printing has already passed by the second conveying unit when the first conveying unit is stopped, the second conveying unit being driven by the same driving source as that for the first conveying unit and being disposed downstream of the printing position.
