A liquid absorber includes a liquid absorption member, a case, and a cover. The liquid absorption member absorbs liquid. The liquid absorption member includes a fiber and a liquid-absorbent resin. The liquid absorption member is stored in the case. The cover covers the liquid absorption member. The cover includes through-holes through which the liquid is to pass. The cover includes a recessed portion recessed toward the liquid absorption member. The recessed portion is disposed at a location to which the liquid is to be discharged. The through-holes are disposed at least in the recessed portion.

A liquid container includes: a case having a liquid introduction port through which liquid is introduced and a storage portion that stores the liquid; and an absorber stored in the case and configured to absorb the liquid. The absorber includes multiple absorbent resins that swell by absorbing the liquid and a substrate that supports the absorbent resins and allows the liquid to permeate therethrough. With the absorbent resins swelling by absorbing the ink, at least some of the absorbent resins are spaced apart from the adjacent absorbent resins.

A liquid ejecting apparatus has a housing constituting the exterior and includes: a liquid ejecting head; a liquid container; a maintenance device; a waste liquid container; a supply tube; a waste liquid tube; and a guide along which the supply tube and the waste liquid tube are routed in parallel. Assuming that one side of the housing is a rear side and another side facing the one side is a front side in plan view, the maintenance device is disposed closer to a rear side than the liquid container is, the liquid ejecting head is disposed at a side of the maintenance device so as to be movable in the left-right direction, and the guide is disposed in an area between the maintenance device and the front side of the liquid container.

A liquid discharging apparatus includes: a first storage which stores liquid; a first detector which detects an amount of the liquid in the first storage; a communication hole communicating the first storage and outside; a semipermeable membrane arranged to cover the communication hole; a head unit having at least one nozzle which discharges the liquid supplied from the first storage; a liquid flow channel which communicates the first storage and the head unit; a cap which seals the nozzle of the head unit; a cap movement mechanism which moves the cap; an electrode arranged in the cap and on which the liquid discharged from the nozzle is landed; a second detector connected electrically to the electrode; a suction mechanism which sucks the liquid and gas inside the cap; a waste liquid storage which stores the liquid sucked from inside of the cap by the suction mechanism; and a controller.

A waste liquid container includes a waste liquid introduction portion being coupled to a discharge portion when the waste liquid container is mounted on a mounting portion, an accommodation portion accommodating waste liquid discharged from the discharge portion, and a restricted portion having a contact portion configured to make contact with a restricting portion and restricting movement of the waste liquid container in a detachment direction opposite to a mounting direction by contact between the contact portion and the restricting portion in a state in which the waste liquid container is mounted on the mounting portion, wherein the contact portion is arranged at a position which does not overlap with a center of an opening of the waste liquid introduction portion in a vertical direction when seen from a side on which the waste liquid introduction portion is opened.

A printer includes a transport unit, a first head, a second head disposed downstream of the first head, a first suction unit configured to suction ink mist discharged from the first head, a second suction unit configured to suction ink mist discharged from the second head, and a suction device coupled to the first suction unit and the second suction unit, and configured to generate an airflow for suctioning the ink mist, and a first suction device disposed either one of on a first path from the first suction unit to the suction device, and at the suction device, and configured to adjust a flow rate at the first suction unit, and a second suction device disposed either one of on a second path from the second suction unit to the suction device, and at the suction device, and configured to adjust the flow rate at the second suction unit.

A liquid absorption system includes a pipe which transports a liquid containing metal ions; a discharge portion which discharges the liquid transported by the pipe; a container which recovers the liquid discharged from the discharge portion; an absorbing portion which is received in the container and which includes a polymer absorbent absorbing the liquid; and a metal ion-concentration decrease portion which decreases a concentration of the metal ions contained in the liquid, and the metal ion-concentration decrease portion is provided at a position at which the metal ion-concentration decrease portion comes in contact with the liquid before the liquid comes in contact with the absorbing portion.

A liquid absorber includes a container that has an opening and that recovers liquid and a first absorbing unit that is constituted by an aggregate of porous absorbing body blocks and that is housed in the container such that a gap exists between the porous absorbing body blocks. The porous absorbing body blocks have a density of 0.05 [g/cm.sup.3] or more and 0.50 [g/cm.sup.3] or less.

The ink absorbing material is a chip aggregate that includes multiple chips each having a fiber-containing fibrous support and an absorbent polymer held by the fibrous support. In the ink absorbing material, each of the chips forming the chip aggregate preferably has the absorbent polymer on at least one side of the fibrous support, with the absorbent polymer adhering to the fibrous support.

A lid covers a waste liquid intake portion of a waste liquid tank that collects a waste liquid. The lid includes an inside opening portion and a communication path portion. The inside opening portion has a first opening to face an interior of the waste liquid tank. The communication path portion to connect the inside opening portion to the atmosphere. The communication path portion has a second opening communicating with the inside opening portion. The first opening is larger in area than the second opening.
