Patent number: 11970004Abstract: A liquid discharge head includes a liquid discharge substrate that has a discharge-orifice row, pressure generating elements, and pressure chambers. The liquid discharge head discharges a liquid in a block-by-block manner using sequential driving. The discharge-orifice row is disposed so as to incline at an angle ?=Arctan (d1/d2) relative to a direction extending orthogonal to the conveyance direction of the medium, in which d1 (?m) is a disposition spacing of the discharge orifices in the discharge-orifice row in the conveyance direction and d2 (?m) is a disposition spacing of the discharge orifices in the discharge-orifice row in the direction orthogonal to the conveyance direction. A partition wall is formed between adjacent pressure chambers so as to separate the adjacent pressure chambers from each other. The partition wall has a communicating portion that communicates the adjacent pressure chambers with each other.Type: GrantFiled: April 12, 2022Date of Patent: April 30, 2024Assignee: Canon Kabushiki KaishaInventors: Tomohiro Sato, Shuzo Iwanaga, Takatsugu Moriya, Koichi Ishida, Shingo Okushima, Shintaro Kasai, Yoshiyuki Nakagawa, Akiko Hammura
