  • Patent number: 10906764
    Abstract: A printing apparatus is capable of preventing a sheet discharged from a discharge unit from entering a feeding unit while guiding the sheet properly to a storage unit located below the feeding unit. The printing apparatus includes a storage unit configured to store a sheet discharged from a discharge unit and a guide unit configured to guide the sheet discharged from the discharge unit to the storage unit. The guide unit has a turning unit which prevents the sheet discharged from the discharge unit from entering a feeding unit and which turns when the sheet comes into contact with the turning unit.

  • Patent number: 10894432
    Abstract: A printing apparatus comprises a conveyance control unit which controls conveyance of printing sheets so that a trailing edge of a preceding sheet as a printing sheet precedingly fed from the stacking unit and a leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other; and a skew correction unit which performs skew correction of the succeeding sheet while the succeeding sheet overlaps the preceding sheet by the conveyance control unit. The skew correction unit makes the leading edge of the succeeding sheet abut against the conveyance roller during a time from an end of a last line feed operation by the conveyance roller for printing on the preceding sheet by the printing unit to start of a next conveyance operation.
