A liquid ejecting apparatus includes a liquid ejecting head ejecting liquid onto a medium transported on a transport path extending in a depth direction, a carriage holding the liquid ejecting head and reciprocally moving in a width direction so as to cross the transport path, and a waste liquid containing portion containing waste liquid discharged from the liquid ejecting head. The carriage includes a plurality of liquid containers that contain the liquid and are mounted on the carriage in such a manner that a plurality of the liquid containers are arranged side by side with each other in the depth direction. A portion of the carriage overlaps the waste liquid containing portion in a vertical direction when the liquid ejecting head is outside the transport path.

When a filter for example is provided in a liquid supply path in the manufacture of a liquid ejection head, the filter can be prevented from being displaced or deformed. A manufacture method of a liquid ejection head having a liquid ejection unit for ejecting liquid and a liquid supply unit for supplying liquid to the liquid ejection unit has a processing of abutting a filter to a melting unit provided in the liquid supply unit and applying heat to the melting unit via the filter to melt the melting unit to thereby fix the filter to the melting unit, and a processing of burying the melting unit fixed to the filter by molding material.

A recording device has: a recording head configured to perform recording on a medium; a medium storage below the recording head configured to store the medium to be recoded; a supply path comprising a first curved supply path curved so as to be convex upward and transporting the medium fed out of the medium storage in a reversed direction via the first curved supply path; and a reversing path comprising a second curved path curved so as to be convex downward and transporting the recorded medium into a direction including a vertically upward component via second curved path from a direction including a vertically downward component; wherein the supply path joins the reversing path, and the first curved path and the second curved path overlap when viewed horizontally.

An image recording apparatus includes a cartridge installing unit for detachably installing a plurality of ink cartridges. The cartridge installing unit includes: a base having a placing surface and aligning the plurality of ink cartridges in a first direction on the placing surface; a moving force applying unit moving an ink cartridge of the plurality of ink cartridges from an installation position to a removal position separated from the installation position in a movement direction including a component of the first direction; and a regulating unit regulating the movement of the ink cartridge from the installation position to the removal position. The moving force applying unit moves the ink cartridge from the installation position to the removal position in a case that the ink cartridge is released from the regulation by the regulating unit.

A liquid cartridge configured to be inserted into a cartridge attachment section includes: a cartridge body having a liquid storage chamber, and a liquid supply portion configured to supply the liquid stored in the liquid storage chamber to an outside. The liquid supply portion includes: a front end face facing frontward, an outer peripheral surface extending rearward from the front end face, and at least one guide provided at the outer peripheral surface. Each of the at least one guide is guided by corresponding at least one projection of the cartridge attachment section during attachment of a liquid supply tube of the cartridge attachment section to the liquid supply portion at a time of attachment of the liquid cartridge to the cartridge attachment section. Each of the at least one guide includes: a first guide portion, and a second guide portion.

Provided is a consumable package assembly including a consumable container and an outer packaging portion. The consumable container includes a chip, and the outer packaging portion includes an accommodating portion for accommodating the consumable container. The outer packaging portion includes a first through hole configured to expose at least a part of the chip, and a second through hole configured to expose at least a part of the accommodating portion so as to position the consumable container. Operation to the chip on the consumable container can be performed without removing the outer packaging portion so as to avoid scrapping of the outer packaging portion, thereby reducing the procedures of the production or the reprocessing and resulting in lower cost and higher efficiency. The second through hole is configured to prevent the unfixed position of the consumable container in the outer packaging portion from resulting inaccurate operation to the chip.

A liquid cartridge includes: a housing including first and second protrusions; and a circuit board including an electrode. The first protrusion is positioned rearward but the second protrusion is positioned forward relative to the circuit board. When viewed in a width direction crossing a gravitational direction, an outline of the liquid cartridge between a first point and a second point is lower than an imaginary line. The imaginary line passes through the first point on the first protrusion and the second point on the second protrusion. A distance between a front edge of the electrode and the first point is smaller than a distance between the front edge and the second point. A dimension between a front end and a rear end of the second protrusion is greater than a distance between a frontmost end of the housing and the front end of the second protrusion.

A sonic speed measurement device includes a reception array in which a plurality of reception elements which output reception signals in response to reception of an ultrasonic wave are disposed in one direction, a phase difference detection portion that detects a phase difference between the reception signals output from the reception elements adjacent to each other in a case where the plurality of reception elements receive the ultrasonic wave which propagates in a spherical wave shape from a target point, and a sonic speed calculation portion that calculates a sonic speed of the ultrasonic wave on the basis of the phase difference.

An ink cartridge adapter or ink cartridge includes a casing; and a plurality of pad electrodes mounted on the casing so as to be movable in a direction outwardly away from a side surface of the casing.

A packaging assembly includes an outer packaging unit, at least one to-be-packaged unit, and a loading unit configured to accommodate the at least one to-be-packaged unit to limit movement of the at least one to-be-packaged unit with respect to the loading unit. The outer packaging unit includes a receiving unit capable of receiving at least a part of the loading unit and the at least one to-be-packaged unit which are fit to each other.
