Abstract: A liquid ejecting device on which a waste liquid storage unit is mounted includes an ejecting unit that ejects a liquid, a maintenance unit and a collecting unit. The maintenance unit includes a receiving unit and a wiping unit that wipes a nozzle surface in which a nozzle is open, by moving together with the receiving unit in one direction. The receiving unit includes a receiver including a receiving tank that receives the liquid discharged from the nozzle, and a receiving gutter in which a discharging hole for dropping the liquid received by the receiving tank onto the collecting unit is open.
The collecting unit includes a discharging gutter that directs the liquid dropped through the discharging hole to the waste liquid storage unit, and the discharging gutter extends in the one direction and overlaps with at least a part of the receiver as viewed in a vertical direction.
