Patent number: 10112399Abstract: A liquid jet apparatus comprises a liquid jet head, a carriage carrying the liquid jet head in a side-to-side direction, a liquid flow channel, and a liquid container in fluid communication with the liquid jet head through the liquid flow channel. The liquid container includes a liquid containing chamber arranged along a front/back direction orthogonal to the side-to-side direction; a liquid outlet port, from which the liquid contained in the liquid containing chamber flows to the liquid flow channel; and a liquid inlet port, through which the liquid is injected into the liquid containing chamber. The liquid inlet port has an end surface that does not face in a vertical direction relative to a normal posture of the apparatus.Type: GrantFiled: January 29, 2016Date of Patent: October 30, 2018Assignee: Seiko Epson CorporationInventors: Shoma Kudo, Takashi Koase, Toshiya Okada, Yasunori Koike, Tetsuya Takamoto, Nobutaka Suzuki, Satoshi Tamai, Toru Nakazawa, Katsutomo Tsukahara, Masayuki Kanazawa, Naofumi Mimura, Keigo Iizawa, Yutaka Kobayashi

Patent number: 9855761Abstract: An ink tank includes a tank main body that is able to contain ink, an ink filling unit that is provided in the tank main body and has an opening which enables the tank main body to be filled with the ink, and a plurality of ribs that are provided around the ink filling unit of the tank main body and protrude from the tank main body. A clearance in which the ink is held due to a capillary force between the ribs is provided between two adjacent ribs among the plurality of ribs.Type: GrantFiled: September 22, 2016Date of Patent: January 2, 2018Assignee: Seiko Epson CorporationInventors: Hidenao Suzuki, Shoma Kudo, Naomi Kimura, Keigo Iizawa, Masayuki Kanazawa, Naofumi Mimura, Keisuke Akimoto, Ryusuke Takakura, Soshi Okawa, Munehide Kanaya, Nobuyuki Nishi, Satoshi Kawamura

Patent number: 9487012Abstract: An ink tank unit includes: an ink tank that is able to contain ink; an ink filling unit that is provided in a case of the ink tank and has an opening which enables the ink tank to be filled with the ink; and a second case that covers at least a part of a peripheral section of the ink filling unit, of a fifth wall of the case on which the ink filling unit is provided. A recessed section and a side wall which enables the ink to be guided to the recessed section are provided on at least one section of the peripheral section of the fifth wall and a section of the second case, which faces the peripheral section.Type: GrantFiled: February 26, 2014Date of Patent: November 8, 2016Assignee: Seiko Epson CorporationInventors: Hidenao Suzuki, Shoma Kudo, Naomi Kimura, Keigo Iizawa, Masayuki Kanazawa, Naofumi Mimura, Keisuke Akimoto, Ryusuke Takakura, Soshi Okawa, Munehide Kanaya, Nobuyuki Nishi, Satoshi Kawamura

Patent number: 9290001Abstract: A liquid container includes an ink chamber containing an ink to be supplied via a tube to a liquid ejecting head consuming the ink; an outlet port from which the ink contained in the ink chamber flows to the tube side; an injection port through which the ink can be injected into the ink chamber; and an air intake port taking air into the ink chamber from a further vertically upper position than a liquid level of the ink when the ink is contained in the ink chamber. If the ink equal to 5% of containing capacity containable in the ink chamber flows from the outlet port, the liquid container has an area where a fluctuation range of the liquid level of the ink inside the ink chamber becomes 5% or less of the cubic root of the containing capacity.Type: GrantFiled: June 10, 2015Date of Patent: March 22, 2016Assignee: Seiko Epson CorporationInventors: Shoma Kudo, Takashi Koase, Toshiya Okada, Yasunori Koike, Tetsuya Takamoto, Nobutaka Suzuki, Satoshi Tamai, Toru Nakazawa, Katsutomo Tsukahara, Masayuki Kanazawa, Naofumi Mimura, Keigo Iizawa, Yutaka Kobayashi
