Abstract: A recording apparatus includes a conveyance unit that conveys a recording medium in a first direction toward a recording head for ejecting a liquid, a tank including a containing chamber containing the liquid to be supplied to the recording head, and an injection port through which the liquid is injected into the containing chamber, the tank being disposed downstream of the conveyance unit in the first direction, a rotatable lever that holds a tank cap for closing the injection port, and a cover that rotates about a rotation shaft between an open position for exposing the lever and a closed position for covering the lever, the rotation shaft being disposed upstream of the conveyance unit in the first direction. The cover includes a sliding portion that is provided on a surface facing the lever and comes into contact with the lever while the cover is rotating toward the closed position.

Abstract: Disclosed is a recording apparatus including a tank configured to store liquid to be supplied to a recording head that ejects the liquid, the tank including an inlet port for liquid injection; a cap unit including a shaft portion and a cap configured to turn about the shaft portion between a first position at which the cap caps the inlet port and a second position at which the cap does not cap the inlet port, the shaft portion being provided to a housing that encloses the tank; and a biasing unit configured to bias the cap unit in a direction to move the cap apart from the inlet port, wherein the cap unit does not move at the second position while being biased by the biasing unit.

Abstract: A technique capable of certainly suppressing adhesion of waste ink to hands, clothes, and the like during replacement of a waste ink tank is provided. There are included a container portion provided with an insertion port which a discharge member discharging waste ink can be inserted into and pulled out from and a shielding portion movable between a shielding position where the insertion port is shielded and an open position where the insertion port is opened.

Abstract: A recording apparatus includes a tank including a chamber configured to store liquid to be supplied to a recording head that ejects the liquid and a filling port from which the liquid is injected into the chamber, and an injection auxiliary member configured to assist injecting of the liquid into the chamber from the filling port, the injection auxiliary member including a first and a second flow channels each defined by a first or a second upper end portion that opens toward outside of the tank and a first or a second lower end portion that opens toward inside of the tank, wherein the second flow channel has an expansion portion arranged in a middle portion between the second upper end portion and the second lower end portion and configured to form a step to expand a cross-sectional area.

Abstract: A printing apparatus includes a support member configured to support a printhead that performs printing by discharging ink to a print medium, a connecting member including a connecting portion connected to an ink introduction portion of the printhead and through which the ink introduction portion communicates with an ink supply passage via the connecting portion, a rotation member configured to hold the connecting member such that a posture of the connecting member is changeable, and configured to be supported by the support member to be rotatable between a connecting position at which the ink introduction portion and the connecting portion are connected and a connection releasing position at which the ink introduction portion and the connecting portion are not connected, and a biasing portion configured to bias the connecting member to a first posture with respect to the rotation member.

Abstract: A method of detecting somatic mutations of tumor marker genes includes recovering a peripheral blood mononuclear cell layer from a blood sample collected from a subject and examining whether or not a nucleic acid derived from tumor marker genes having somatic mutations is detected from DNA included in the peripheral blood mononuclear cell layer.
