A liquid ejecting device includes a liquid ejecting portion configured to eject liquid from a nozzle, a closed space forming portion having a porous member inside thereof, and configured to form a closed space in which the nozzle opens, an discharging portion configured to discharge the liquid in the closed space forming portion, and a control portion configured to, when an amount of the liquid ejected from the liquid ejecting portion into the closed space forming portion reaches a prescribed value, cause the discharging portion to discharge the liquid in the closed space forming portion, wherein the control unit decreases the prescribed value as the number of stops increases, the number of stops being the number of times the liquid ejecting portion is stopped for a prescribed time or longer at a position other than a closed position where the closed space is formed.

Printing apparatus for printing by discharging ink to an upper surface of a base material in the form of an elongated strip

Since a head part is arranged in an inclined posture, the ink ejected from a nozzle surface of the head part may drip to a first lower surface peripheral edge portion along the nozzle surface, and then drops from a first long side of a lower surface of the head part toward a first side wall of a cover member being arranged below the head part. The first side wall having an upper end portion is located away from the first long side. Thus, the dropped ink is collected by the cover member without being attached to the upper end portion of the first side wall. Therefore, the ink can be prevented from being solidified at the first lower surface peripheral edge portion and the reattachment of the ink to the nozzle surface can be effectively prevented.

RECORDING DEVICE
