Patent number: 9694588Abstract: 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.Type: GrantFiled: May 5, 2016Date of Patent: July 4, 2017Assignee: Seiko Epson CorporationInventors: Takayuki Shiota, Atsushi Kobayashi, Tadahiro Mizutani, Shun Oya

Patent number: 9682565Abstract: Cartridges 4 and 5 are configured, such that first convex ribs 428a and 528a abut against second wall surfaces 762 of cartridge engagement wall surfaces 760 inclined with respect to a bottom wall 712 of a cartridge attachment structure 7 and move in friction with the second wall surfaces 762. Such abutting and moving causes contact portions of terminals 412 and 512 of circuit substrates 410 and 510 of the respective cartridges 4 and 5 to come into contact with electrode assemblies 810 of a carriage 8. This configuration enhances the reliability of electric connection between a contact portion, such as a circuit substrate, of a liquid supply unit and an electrode assembly, such as contact pins, of a carriage in the course of attachment.Type: GrantFiled: December 10, 2015Date of Patent: June 20, 2017Assignee: Seiko Epson CorporationInventors: Tadahiro Mizutani, Atsushi Kobayashi, Shun Oya
