  • Patent number: 11833836
    Abstract: A printing apparatus includes: a tube configured to form a flow channel to supply a liquid to a liquid ejecting unit configured to eject the liquid; a holding unit configured to hold the tube; and a valve unit configured to move to a closed position to press and close the tube held by the holding unit with a pressing portion from an open position to open the tube held by the holding unit, and to move to the open position from the closed position. Here, the valve unit includes a pivot shaft and moves pivotally around the shaft to move to the closed position and the open position, and a direction of extension of the pivot shaft is a direction intersecting with a direction of extension of the tube held by the holding unit.
    Type: Grant

  • Patent number: 10065439
    Abstract: A printing apparatus includes a printhead on a movable carriage; an operating unit operating by a driving force of a driving source; a transmitting unit being displaced by the driving force between a position where the transmitting unit transmits the driving force to the operating unit and a non-transmitting position; a movable member arranged on a moving path of the carriage; a restricting member being displaced, in coordination with a displacement of the movable member, between a position where the displacement of the transmitting unit is restricted and a non-restricting position; and a selecting member provided between the movable member and the restricting member. The selecting member is displaced between a position where the movable member and the restricting member are coordinated with each other by the selecting member and a non-coordinating position.

  • Patent number: 9776815
    Abstract: A feeding device includes a roller configured to feed an uppermost sheet of a plurality of sheets stacked in a stacking unit, and an inclined separator located downstream of the roller in a feed direction and configured to separate one sheet from another sheet. The inclined separator includes a first separator and a second separator that are arranged along the feed direction. Resistance imparted to each sheet by the first separator is greater than resistance imparted to each sheet by the second separator.
