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.

Recording apparatus

A printing apparatus includes a liquid storing container including a storage chamber configured to store a liquid supplied to a printing unit that prints an image by discharging the liquid, an outlet portion of the liquid, and a channel configured to connect the storage chamber and the outlet portion. The liquid storing container includes a first side portion on a side of a print region where printing is executed by the printing unit, and a second side portion on an opposite side of the first side portion, and the channel is formed in the second side portion.

Printing apparatus and liquid storing container

A recording apparatus includes a recording head having discharge orifices arranged on a discharge orifice surface, a cap, a wiper, and a moving unit that moves the wiper in a first direction. When the cap covers the discharge orifice surface, a first member is disposed at an inside wall of the cap at a position near a first side of a region having the discharge orifices, and a second member is disposed at another inside wall of the cap at a position near a second side of the region having the discharge orifices. The first side faces in a direction opposite to the first direction and the second side faces in the first direction. In a direction normal to the discharge orifice surface, a distance between the second member and the discharge orifice surface is smaller than a distance between the first member and the discharge orifice surface.

A liquid discharge apparatus includes a discharging unit configured to be capable of discharging a plurality of kinds of liquids onto a medium, and a waste liquid tank including a storage part configured to store a waste liquid of the liquid. The waste liquid tank includes a first inflow port and a second inflow port from which the waste liquid flows into the storage part, and a restriction portion located between the first inflow port and the second inflow port, and configured to restrict movement of the waste liquid in the storage part.

Liquid discharge apparatus and waste liquid tank

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.

Recording apparatus and tank

A print head includes a nozzle array comprising a plurality of nozzles, and a negative pressure generating portion configured to apply a negative pressure to the nozzle array. A tank includes a storage portion and an air communication port. A tube connects the print head and the tank and supply the liquid from the tank to the print head. A highest position of a liquid level in the tank in the vertical direction is higher than a position of the nozzle array, and an absolute value of a water head difference caused by a difference between the highest position of the liquid level in the tank and the position of the nozzle array is not larger than an absolute value of a negative pressure generated by the negative pressure generating portion.

Printing apparatus

Provided is an image recording apparatus including: a carriage configured to support a recording head that ejects a liquid to a recording medium and configured to perform reciprocating motion in the scanning direction; a liquid containing portion configured to contain liquid; a tube configured to connect the recording head and the liquid containing portion to supply liquid from the liquid containing portion to the recording head, the tube including a first section that extends in the scanning direction and a second section that extends in the scanning direction above the first section; and a support portion configured to support the first section and be secured to an apparatus main body, and in the support portion, a rotating member is provided below the second section at a position facing the second section.

Image recording apparatus

An ink jet printing apparatus includes a first fixing member including a first coupling portion coupled to a cap-side end of a first pump tube and a second coupling portion coupled to a waste ink storage portion-side end of a second pump tube. The distance from a reference surface of a pump base to the first coupling portion is different from the distance from the reference surface of the pump base to the second coupling portion.

Ink jet printing apparatus having low-noise compact pump tube capable of raising suction pressure

Even in printing apparatus that make use of a plurality of kinds of sheets, the degradation of image quality is reduced. A sheet conveying apparatus includes: a sheet stacking unit; a sheet conveying unit being in contact with the sheet stacked on an uppermost portion, of the stacked sheets, and conveying the sheet; a separation unit separating the sheets into only one sheet of the uppermost portion by a separation slope that abuts a tip portion of the sheet conveyed by the sheet conveying unit; and a guide unit connected to the separation unit and guiding the sheet, in which an angle between the sheet stacking unit and the separation slope is switched to a first angle and a second angle smaller than the first angle by a rotation center of the separation unit provided in a vicinity of a connection portion of the separation unit and the guide unit.

Sheet conveying apparatus, printing apparatus, and processing apparatus

In an inkjet printing apparatus capable of automatic duplex printing, time required to fix ink is shortened and throughput is improved without producing uneven fixing. The inkjet printing apparatus includes a printing unit that prints onto a sheet, a fixing unit that heats a sheet printed by the printing unit, a conveying unit that conveys a sheet with respect to the printing unit and the fixing unit, and a controller that controls the conveying unit such that a printing region of a sheet printed on the first side by the printing unit passes through the fixing unit, and afterwards, the conveyance direction of the sheet is reversed in order to print on the second side and the printing region once again passes through the fixing unit. The controller variably controls the conveyance speed of the sheet when the printing region once again passes through the fixing unit.

Inkjet printing apparatus

A sheet conveying device includes a first conveying unit configured to convey a sheet in a conveying direction; a conveying path configured to guide the sheet to the first conveying unit, the sheet having been conveyed by the first conveying unit in a direction opposite to the conveying direction; a second conveying unit configured to convey the sheet in the conveying path; a rotation direction detecting unit configured to detect a rotation direction of the second conveying unit; and a control unit configured to perform control, at startup, to drive the first conveying unit in a direction that causes the sheet to be conveyed in the conveying direction, and if the rotation direction detecting unit detects rotation of the second conveying unit, to drive the second conveying unit in the rotation direction that is detected by the rotation direction detecting unit.
