A pressure control unit includes a liquid storage chamber, an inflow port that allows the liquid to flow therein, and an outflow port that allows the liquid to flow out thereof, the pressure control unit controlling pressure of the liquid, wherein at least part of an outer wall of the liquid storage chamber is formed of a flexible film, a pressing plate that presses the flexible film, an urging member that urges the pressing plate, and a valve that opens and closes the outflow port. The pressing plate moves in a direction of expanding the liquid storage chamber, whereby the valve in contact with the pressing plate moves and makes a valve opening degree of the outflow port high. A range of motion of the valve when making the valve opening degree of the outflow port high is limited by a member other than the pressing plate.

In one example in accordance with the present disclosure, a printing fluid container for a printing system is described. The printing fluid container includes a container body for holding printing fluid, a collar connected to the container body, and a cap removably engaging the collar. The collar has a plurality of collar teeth extending peripherally around the collar. The cap has a plurality of cap teeth extending peripherally around the cap. The cap teeth are configured for interfitment with the collar teeth such that rotation of the cap about the longitudinal axis in a first rotational direction effects cam-actuated removal of the cap from the collar.

Provided is a discharged liquid container detachable to an apparatus having an outlet portion from which discharged liquid is to be drained, and configured to contain the discharged liquid drained from the outlet portion. The discharged liquid container includes a casing inside which the discharged liquid is containable, a connection portion provided in a first face of the casing and configured to be coupled to the outlet portion, and a lid portion configured to change in position between a closed state for covering the connection portion and an open state for opening the connection portion. The lid portion is configured to be in the open state in a state of attachment of the casing to the apparatus and be in the closed state in a state of detachment of the casing from the apparatus.

A supply unit in which a liquid container including a coupling portion being detachably mounted includes: a liquid introduction unit coupled to the coupling portion of the liquid container; an urging member that urges the liquid container in an uncoupling direction which is a direction opposite to a coupling direction, the coupling direction being a direction in which the liquid container is coupled to the liquid introduction unit; and an engagement lever having an engaging portion that engages with the liquid container when the liquid container is coupled to the liquid introduction unit, the engagement lever includes an operating portion operated by a user and a pressing portion configured to press the liquid container and is configured to release the engagement of the engaging portion with the liquid container when the operating portion is operated and to press the liquid container in the uncoupling direction by the pressing portion.

A recording apparatus includes a recording head configured to discharge a liquid, a first liquid reservoir unit configured to store the liquid to be supplied to the recording head, a liquid supply port configured to supply the liquid stored in the first liquid reservoir unit into the recording head, a liquid supply path connecting the first liquid reservoir unit and the liquid supply port, a second reservoir unit, in the recording head, configured to store the liquid supplied from the liquid supply port, and a holding unit configured to hold the liquid supplied from the second reservoir unit, in the recording head, wherein the second reservoir unit includes an opening provided upward in a direction of a gravitational force with respect to the liquid supply port and is configured to supply the liquid to the holding unit, when the recording head is in a posture of performing recording.

A liquid absorber of the present disclosure includes: a first base material; a second base material; and an absorption layer provided between the first base material and the second base material, in which the first base material and the second base material both contain a flame-retardant filament nonwoven fabric, and a content of a flame retardant in the absorption layer is less than 10% by mass.

An ink cartridge includes an ink chamber that stores ink. A protruding chamber protrudes upward from the ink chamber in a gravitational direction when the ink cartridge is used. A swing body has a float and a detection portion, and a detection chamber in which the detection portion moves and with which an amount of ink stored in the ink chamber is detected in accordance with a position of the detection portion. In the ink cartridge, a pivot center of the swing body that pivotally moves is disposed inside the protruding chamber.

A monochrome inkjet printer used only for monochrome recording includes a first ink reservoir configured to accommodate dye ink, a first recording head communicating with the first ink reservoir and configured to record an image using the dye ink, a second ink reservoir configured to accommodate pigment ink, and a second recording head communicating with the second ink reservoir and configured to record an image using the pigment ink. At least one of the first ink reservoir and the second ink reservoir includes an ink injection port compatible with an ink bottle.

An inkjet printer includes a support member configured to support a recording medium moving in a first direction, a carriage configured to reciprocate in a second direction orthogonal to the first direction and provided with a first electrical contact and a second electrical contact, a first recording head mounted on the carriage so as to contact the first electrical contact and configured to reciprocate together with the carriage, and an electrical contact protection member mounted on the carriage so as to contact the second electrical contact and configured to reciprocate together with the carriage. A shortest distance between the electrical contact protection member mounted on the carriage and the support member in a third direction is greater than a shortest distance between the first recording head mounted on the carriage and the support member in the third direction, the third direction being orthogonal to the first and second directions.

A recording apparatus 101 includes a liquid storage portion 46 configured to store liquid, a recording head 22 that ejects liquid supplied from the liquid storage portion 46 onto the medium, and a light emitting unit 301 configured to emit light, wherein the liquid storage portion 46 has a float 48 configured to float on liquid in the liquid storage portion 46 and to move according to movement of liquid surface LS while maintaining a posture, and a front surface 43F in which the liquid in the liquid storage portion 46 is visually checkable from outside the liquid storage portion 46, wherein the float 48 has a front surface 48a that by receiving the light from the light emitting unit 301, appears luminous when viewed from a direction facing the front surface 43F.
