摘要： A liquid container comprises a liquid supply port provided in a bottom wall, a first chamber configured to contain a liquid, a second chamber configured to contain the liquid and to include at least one sub-chamber having a smaller dimension in the X direction than that of the first chamber, a partition wall configured to part the first chamber from the second chamber, and a connecting hole configured to connect the first chamber with the second chamber. The second chamber is connected with the liquid supply port, and the first chamber is connected with the liquid supply port via the connecting hole and the second chamber. The liquid contained in the first chamber is flowed from the connecting hole into the second chamber and is subsequently introduced through the sub-chamber to the liquid supply port.

摘要： A cartridge includes: a case; an accommodation part inside of the case; a liquid leading-out port; a cartridge side electrical connection part; and a cartridge side fixation structure. Engagement of the device side fixation structure and the cartridge side fixation structure restricts moving the case in a state of being imparted with the force directing to −Z direction. The cartridge side fixation structure and the cartridge side electrical connection part overlap with each other at least in a part when the cartridge is viewed in Z directions. A width of the cartridge in the Z direction is smaller than a width in Y direction and a width in the X directions.

摘要： A technique of enhancing attachment of a liquid supply unit to a liquid ejection device is provided. A first ink cartridge 100a and a second ink cartridge 100b are attached to a carriage 27 of a printing device 10 via a holder structure 200. Each of the first and the second ink cartridges 100a and 100b includes a circuit substrate 130 having a plurality of terminals 151 to 159 which are electrically connected with a device-side terminal assembly 250 provided on the holder structure 200. Each of the first and the second ink cartridges 100a and 100b also includes a main engagement part 120 configured to engage with a lever member 230 of the holder structure 200 as an engaged part, such as to limit motion of the circuit substrate 130 away from the holder structure 200. The circuit substrate 130 includes a first terminal 151 and a second terminal 152 located on respective ends in an array direction of the terminals. The main engagement part 120 has a width greater than an interval between contact portions CP of the first and the second terminals 151 and 152 in the array direction of the terminals.

摘要： A cartridge 5 is mounted on a carriage 8. The carriage 8 includes liquid introducing parts 710m, 710c and 710y and a guide projection 723. The guide projection 723 is extended from between the liquid introducing parts 710m and 710c toward the liquid introducing part 710y. The cartridge 5 includes an ink supply port 507m connectable with the liquid introducing part 710m to supply magenta ink to the liquid introducing part 710m, an ink supply port 507c connectable with the liquid introducing part 710c to supply cyan ink to the liquid introducing part 710c, an ink supply port 507y connectable with the liquid introducing part 710y to supply yellow ink to the liquid introducing part 710y, and a first groove 580. The first groove 580 is extended from between the ink supply port 507m and the ink supply port 507c toward the ink supply port 507y to allow for insertion of the guide projection 723. This configuration suppresses diffusion of ink leaked from any of the liquid supply ports of the cartridge.

摘要： A recording apparatus comprises a printer body having a case. An ink nozzle is in the interior of the printer body. An opening and closing member is movably affixed to an upper side of the printer body and is configured to open and close. An external tank is located exterior to the printer body. A tube, a portion of which is exterior to the printer body, provides a liquid from the external tank to the ink nozzle. One or both of the printer body and the opening and closing member are configured to define a tube insertion part, which has a cutout portion or a finger engage portion. The tube extends into the printer body through the cutout portion or the finger engage portion.

摘要： A technique of enhancing attachment of a liquid supply unit to a liquid ejection device is provided. A first cartridge 100a and a second cartridge 100b are attached to a carriage 27 of a printing device 27 via a holder structure 200. The holder structure 200 has a lever member 230 rotated and moved to engage with a main engagement part 120 of each of the first and the second cartridges 100a and 100b. Each of the first and the second cartridges 100a and 100b has a first side wall portion 125 and a second side wall portion 126 configured to press the lever member 230 and rotate and move the lever member 230 forward in the course of attachment of the first or the second cartridge 100a or 100b to the holder structure 200. A rotation axis RX of the lever member 230 is located at a position closer to an ink supply port 110 or 110a than the first side wall portion 125 and the second side wall portion 126 in the course of attachment of the first or the second cartridge 100a or 100b.
