  • Patent number: 10730323
    Abstract: A printing apparatus includes first and second supplying portions, a printer, and a winding unit. The first supplying portion can supply a recording medium on a conveyance route to the printer for first surface printing. The winding unit then rotates in a first direction to wind the printed recording medium. A wound recording medium edge is located at a specific location and then guided to a conveyance route opening portion if the wind direction is a second direction. After the edge is at the specific location, the recording medium is supplied through the opening portion to the printer for second surface printing. If the second supplying portion supplies the recording medium for first surface printing, then it supplies the medium for second surface printing. If a user sets a wound-in-advance recording medium to the second supplying portion, the second supplying portion supplies the set recording medium to the printer.

  • Patent number: 8857973
    Abstract: A sheet conveying device having a rolled-sheet supporting unit, a conveying unit, a driving unit, a tension applying unit, and a control unit. The rolled-sheet supporting unit supports a continuous sheet rolled up into a roll. The conveying unit conveys the continuous sheet from the rolled-sheet supporting unit as driven by the driving unit. The tension applying unit applies tension to the continuous sheet downstream of the conveying unit in a conveying direction. The control unit controls a driving amount of the driving unit per unit conveyance distance as the conveying unit conveys the continuous sheet. The driving amount is larger in a case where a first tension is applied by the tension applying unit compared to a case in which a second tension, that is larger than the first tension, is applied.
