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.

A cartridge 4 is mounted on a carriage 8 and has a liquid retaining member 460 placed in a recess 421 of a casing 420. A first side wall 425 constituting the casing 420 includes a first side wall part 425a and a second side wall part 425b aligned sequentially from a first end wall 423-side in a first direction from a first end wall 423 toward a second end wall 424. The first side wall part 425a includes a first side wall area 425a1 located on a bottom wall 422-side and extended to be substantially perpendicular to the bottom wall 422, and a second side wall area 425a2 arranged to be inclined with respect to the bottom wall 422. The second side wall part 425b is extended from the bottom wall 422 to be inclined with respect to the bottom wall 422. This configuration enables the liquid retaining member of containing a liquid such as ink to be compressed in the casing, while allowing for accurate positioning of the cartridge and improving attachment of the cartridge.

In an ink jet print head, a fluid passage forming substrate 1 includes pressure generating chambers 2 being trapezoidal in shape, each pressure generating chamber 2 having walls substantially parallel to the flowing direction of ink, and no stagnation of ink is present in the pressure generating chambers 2. The pressure generating chambers' 2 walls include first walls 3, 3' vertical to the surface of the silicon monocrystalline substrate and oriented in the orientation of the pressure generating chambers 2, and second walls 4, 4' slanted at an angle of 35° with respect to the surface of the substrate 1, the second walls 4, 4' being formed at both ends of each pressure generating chamber 2. An elastic plate 5 is fastened onto first opening-formed sides of the pressure generating chambers 2 and piezoelectric layers 7, 8, 9 for expanding and contracting the pressure generating chambers 2 are mounted on the surface of the elastic plate 5. A covering member 10 has nozzle openings 11 each located at the end of each pressure generating chamber 2 which are firmly fastened to second opening-formed sides of the pressure generating chambers 2. The covering member 10 is firmly fastened on the fluid passage forming substrate 1 by an adhesive layer 13.

A cartridge 4 has liquid supply ports 407b, 407c, 407y and 407m formed on a bottom wall 422 of a casing 420 and configured to be in contact with corresponding liquid introducing parts 710b, 710c, 710y and 710m of a carriage 8, and a circuit substrate 410 provided on a second wall surface portion 423b of a first end wall 423 intersecting with the bottom wall 422 and configured to be in electrically contact with an electrode assembly 810 of the carriage 8. In a plan view of the bottom wall 422 of the cartridge 4 in a first direction toward the bottom wall 422, the distance between a second end wall 424 and a first wall surface portion 423a of the first end wall 423 is set to be greater than the distance between the second end wall 424 and the second wall surface portion 423b. This configuration allows for downsizing of the entire liquid supply unit such as cartridge.
