There is provided an ink jet recording apparatus capable of preventing a user from erroneously performing an opening and closing operation of a valve in the supply of ink to a recording head from an ink tank. The ink jet recording apparatus includes a recording head configured to eject ink, an ink tank provided in an apparatus body, including an filling portion for filling ink to be supplied to the recording head, and configured to store the filled ink, a cover member configured to be movable to a position where the filling portion is not exposed and a second position where the filling portion is exposed, and a valve configured to be switchable between an opened state where ink can be supplied to the recording head from the ink tank and a closed state where the supply of ink to the recording head from the ink tank is blocked, wherein the valve operates interlocking with the movement of the cover member, and is in the opened state when the cover member is at the first position and in the closed state when the cover member is at the second position.

Ink jet recording apparatus

A printing apparatus includes a printing unit, and first, second, and third conveyance paths. The printing unit performs printing at a printing position on a print medium conveyed in a conveyance direction. The first conveyance path causes the print medium to pass through the printing position of the printing unit. The second conveyance path reverses obverse and reverse surfaces of the print medium, and the third conveyance path reverses obverse and reverse surfaces of the print medium. The second conveyance path branches from the first conveyance path at a first branching point on a downstream side of the printing position in the conveyance direction and merges into the first conveyance path on an upstream side of the printing position. The third conveyance path branches from a second branching point on the second conveyance path and merges into the first conveyance path on the upstream side of the printing position.

Printing apparatus

A printing apparatus includes a supply unit, a supply path, first and second conveyance paths, a printing unit, and an inversion roller. The first conveyance path conveys, to a first direction, a print medium. The printing unit prints an image on the two surface of the print medium. The inversion roller inverts a conveyance direction of the print medium and conveys the print medium in a second direction. The second conveyance path conveys the print medium conveyed in the second direction to the first conveyance path while inverting the print medium. When performing printing on both sides of print media, the print media are convey such that a first print medium supplied from the second conveyance path and a second print medium supplied from the supply path overlap in the first conveyance path.

Printing apparatus, control method thereof, and storage medium to reduce a size of a printing apparatus without a deterioration in productivity of double-sided printing

An ink tank that enables to check whether a cover of an ink tank is normally bonded to the ink tank includes a first chamber having a supply port for supplying ink to a printing head that ejects ink, a second chamber having an external air introduction port capable of introducing external air, a partition wall configured to separate the first chamber and the second chamber, a communication path provided in the partition wall and configured to place the first chamber and the second chamber in communication with each other, a first cover member configured to cover an opening of the first chamber without extending over an opening of the second chamber, and a second cover member configured to cover the opening of the second chamber without extending over the opening of the first chamber.

Ink tank and ink jet printing apparatus

The printing apparatus of the present invention includes: a print head; and a liquid storage container in which a liquid storage chamber that stores a liquid to be supplied to the print head, an atmosphere communication chamber that communicates with the atmosphere, and a communication flow path that causes the liquid storage chamber and the atmosphere communication chamber to communicate are formed integrally. The liquid storage container can take a first posture in which the atmosphere communication chamber is located under the liquid storage chamber in the direction of gravity and a second posture in which the atmosphere communication chamber and the liquid storage chamber are located side by side in the horizontal direction. In the case where the liquid storage container is in the second posture, the liquid injection portion and the communication flow path are located on the upper side of the liquid storage container.

Printing apparatus and liquid storage member

A recording apparatus to record an image on a sheet includes a roller pair and a switching unit. The roller pair sandwiches the sheet between the roller pair to convey the sheet. The switching unit switches between a first state in which the roller pair sandwiches the sheet and a second state in which rollers of the roller pair are separated from each other. The switching unit includes a first movable member that is moved in a first direction so that the first state is switched to the second state, and includes a second movable member that is moved in a second direction different from the first direction so that the first state is switched to the second state.

Recording apparatus

There is provided an ink jet recording apparatus capable of preventing a user from erroneously performing an opening and closing operation of a valve in the supply of ink to a recording head from an ink tank. The ink let recording apparatus includes a recording head configured to eject ink, an ink tank provided in an apparatus body, including an filling portion for filling ink to be supplied to the recording head, and configured to store the filled ink, a cover member configured to be movable to a position where the filling portion is not exposed and a second position where the filling portion is exposed, and a valve configured to be switchable between an opened state where ink can be supplied to the recording head from the ink tank and a closed state where the supply of ink to the recording head from the ink tank is blocked, wherein the valve operates interlocking with the movement of the cover member, and is in the opened state when the cover member is at the first position and in closed state when the cover member is at the second position.

The printing apparatus according to the present invention includes a carriage, a supply tube, a head set cover that moves to a first orientation at which the printing head is fixed to the carriage and a second orientation at which the printing head is attachable to or detachable from the carriage, and a joint unit that moves to a first position connected to the printing head and a second position separated from the printing head, wherein the joint unit does not move to the first position from the second position when the head set cover moves to the first orientation from the second orientation, and moves to the second position from the first position in cooperation with movement of the head set cover when the head set cover moves to the second orientation from the first orientation.
