Patent number: 11926152Abstract: A printing apparatus includes a carriage mounted with a printing unit; a first motor configured to move the carriage in a predetermined direction; a second motor configured to move the carriage in the predetermined direction; and a control unit. The control unit executes a first mode in which, when causing the printing unit to perform printing under a first printing condition, the first motor is driven in a first direction and the second motor is driven in the first direction, and a second mode in which, when causing the printing unit to perform printing under a second printing condition different from the first printing condition, the first motor is driven in the first direction and the second motor is driven in the first direction while changing an output ratio between the first motor and the second motor.Type: GrantFiled: May 12, 2022Date of Patent: March 12, 2024Assignee: Canon Kabushiki KaishaInventors: Ryohei Maruyama, Daigo Kuronuma, Masakazu Nagashima, Tomohito Abe, Kenta Iimura, Hiromasa Yoneyama, Naoaki Wada, Kichinosuke Hirokawa, Akira Fujikake, Toshiaki Yamaguchi, Hideyuki Nozawa

Publication number: 20220363081Abstract: A printing apparatus include a carriage mounted with a printing unit, a belt, a first motor configured to drive the belt at one end in the widthwise direction, a second motor configured to drive the belt at the other end in the widthwise direction, and a control unit configured to control the first motor and the second motor. The control unit performs first control by driving the first motor in which the carriage moves from a state in which the carriage is stopped. In the first control, an output of the second motor is controlled from a first state lower than an output of the first motor to a second state higher than the first state.Type: ApplicationFiled: May 12, 2022Publication date: November 17, 2022Inventors: Tomohito Abe, Kenta Imura, Kichinosuke Hirokawa, Akira Fujikake, Toshiaki Yamaguchi, Daigo Kuronuma, Masakazu Nagashima, Naoaki Wada, Ryohei Maruyama, Hideyuki Nozawa, Hiromasa Yoneyama

Publication number: 20220363079Abstract: A printing apparatus includes a carriage mounted with a printing unit configured to perform printing on a print medium, a first motor used to move the carriage, a second motor used together with the first motor to move the carriage, and a control unit configured to control the first motor and the second motor. When moving the carriage, the control unit controls the first motor with a first control amount and controls the second motor with a second control amount. The first control amount and the second control amount are different from each other, and a ratio therebetween is a predetermined ratio.Type: ApplicationFiled: May 12, 2022Publication date: November 17, 2022Inventors: Naoaki Wada, Daigo Kuronuma, Masakazu Nagashima, Tomohito Abe, Ryohel Maruyama, Kenta limura, Hiromasa Yoneyama, Kichinosuke Hirokawa, Akira Fujikake, Toshiaki Yamaguchi, Hideyuki Nozawa
