A liquid ejecting apparatus includes a liquid ejecting head configured to eject a liquid onto a medium; a maintenance unit that performs a maintenance operation for the liquid ejecting head; a mounting mechanism in which is mounted a waste liquid container that houses a portion of the liquid discharged as a waste liquid from the liquid ejecting head; and an access area that is provided vertically below a transport path along which the medium is transported and that is accessible from an apparatus front side, which is a downstream side in a transport direction in which the medium is transported, the mounting mechanism including a housing portion that houses the waste liquid container and being disposed so that a mounting port for mounting the waste liquid container in the housing portion opens to the access area.

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 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.

An ink absorber includes: an ink absorbing member that is capable of absorbing ink; an accommodation section that accommodates the ink absorbing member; and a detachment structure section that detaches the ink absorbing member from the accommodation section. In the ink absorber, it is preferable that the accommodation section have a bottom section and side wall sections standing up from the bottom section, that inclined surfaces inclined relative to the bottom section be formed inside the side wall sections, and that the detachment structure section be configured with the inclined surfaces.

An image forming apparatus includes a container guide and a latch mechanism. The latch mechanism includes a pin and a pin supporting member. The latch mechanism permits an attachment of the ink container to the container guide when the ink container is pushed in an attachment direction and the pin is stored in a first storage part and permits a detachment of the ink container from the container guide when the ink container attached to the container guide is pushed in the attachment direction and the pin is removed from the first storage part. The pin supporting member includes a boss. The boss is stored in a second storage part when the pin is stored in the first storage part, and the boss is removed from the second storage part when the pin is removed from the first storage part.

A liquid absorber includes a liquid absorption member, a case, a cover member, and a filler member. The liquid absorption member absorbs at least a portion of a liquid. The liquid absorption member includes at least one of an assembly of fibers and an assembly of fiber substrates. The liquid absorption member is stored in the case. The cover member is coupled to the case. The filler member is disposed between the liquid absorption member and the cover member. The filler member is a member through which at least a portion of the liquid is to pass. A bulk density of the filler member is less than a bulk density of the liquid absorption member.

A liquid collecting device to collect liquid stored in a storage portion of a liquid container includes a bottle main body, a collecting joint portion, and a first valve element. A flow passage member of the liquid container ports the liquid to the storage portion. The bottle main body has first and second openings in communication with outside the liquid collecting device. The collecting joint portion connects to the bottle main body through the first opening and includes a first coupling portion coupled to the flow passage member, and an internal flow passage extending between the first opening and the first coupling portion. The internal flow passage includes a throttle portion and a space. The first valve element is moveably provided in the space and the first valve element has an area larger than an opening area of the first opening and an opening area of the throttle portion.

A liquid discharging apparatus, having a housing, a first tray for storing a printable medium, a second tray for storing a printable medium, a liquid discharging head, and a first waste liquid storage, is provided. The second tray is located at a position lower than the first tray. The liquid discharging head has nozzles for discharging liquid. The first waste liquid storage is demountably mounted in the housing. The first waste liquid storage is configured to store waste liquid being the liquid discharged from the nozzles of the liquid discharging head. The first waste liquid storage is located between the first tray and the second tray.

A printer device includes: an ink circulation flow path in which ink is circulated; a discharge head that discharges the ink supplied from the ink circulation flow path; a circulation pump and a circulation motor that circulate the ink in the ink circulation flow path; a circulation filter provided in the ink circulation flow path; and control unit that determines a blocked state of the circulation filter and performs drive control of the circulation motor in accordance with a determination result, and the control unit drives the circulation motor in a first mode until it is determined that the circulation filter is in a blocked state, and after it is determined that the circulation filter is in a blocked state, the control unit drives the circulation motor in a second mode that provides a smaller circulation rate than the first mode.

A wipe unit cleans a recording head having an ink discharge surface on which an ink discharge opening that discharges an ink onto a recording medium opens. The wipe unit includes a wiper and a collecting tray. The wiper wipes off an ink forcibly extruded from the ink discharge opening. The collecting tray is arranged under the wiper. The collecting tray collects the ink wiped off with the wiper. The collecting tray includes a discharge port and a plurality of ribs. The discharge port discharges the collected ink downward, and the plurality of ribs are arranged so as to surround a peripheral area of the discharge port and arranged with a predetermined interval from one another in a circumferential direction of the discharge port.
