Abstract: A liquid discharge apparatus includes a discharge portion capable of discharging a liquid, a carriage movable along scanning directions between a first position and a second position, a tube that is connected to the discharge portion and that supplies the liquid to the discharge portion, a frame provided at such a position as to be able to contact the tube, and a tube support portion that is provided between the frame and the carriage and that has a supporting surface capable of supporting the tube. The carriage includes an inclined portion that is inclined so as to move the tube toward the supporting surface when the carriage moves along the scanning directions while the tube is not supported by the supporting surface.

Abstract: A liquid ejection device includes a transport unit, a medium support unit, a liquid ejection head and a negative pressure generating unit. The medium support unit is arranged on a downstream side of the transport unit, and has a medium support surface on which the ejection medium is supported by suction using negative pressure. The medium support unit includes a plurality of first and second recesses arranged on the medium support surface and aligned in a width direction orthogonal to a transport direction. The first recesses are in communication with the negative pressure generating unit. The second recesses are configured and arranged to accept the liquid ejected from the liquid ejection head. Each of the second recesses includes a communication unit communicating with one of the first recesses and a vent hole configured and arranged to allow ventilation without being in communication with the negative pressure generating unit.

Abstract: A liquid ejection device includes a transport unit, a medium support unit and a liquid ejection head. The medium support unit includes a plurality of first recesses and a plurality of second recesses arranged on a medium support surface along a width direction orthogonal to a transport direction. The first and second recesses are configured and arranged to be imparted with negative pressure. A width dimension of an opening of the first recess in the width direction is larger on the downstream side than on an upstream side. A width dimension of an opening of the second recess in the width direction is smaller than the width dimension of the opening of the first recess in the width direction on the downstream side with respect to the transport direction. The second recesses are configured and arranged to accept the liquid ejected toward the ejection medium from the liquid ejection head.
