Patent number: 11999175Abstract: A printing apparatus includes a carriage mounted with a printing unit, a belt, a first motor configured to drive the belt at one end in a 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 control, the second motor is controlled from a first state in which its torque is lower than that of the first motor to a second state in which its torque is higher than that in the first state.Type: GrantFiled: May 12, 2022Date of Patent: June 4, 2024Assignee: Canon Kabushiki KaishaInventors: Tomohito Abe, Kenta Iimura, Kichinosuke Hirokawa, Akira Fujikake, Toshiaki Yamaguchi, Daigo Kuronuma, Masakazu Nagashima, Naoaki Wada, Ryohei Maruyama, Hideyuki Nozawa, Hiromasa Yoneyama

Patent number: 11929655Abstract: An embodiment includes: a first transport module on which a carriage moves; a second transport module that is configured to be able to move to a position for connecting to the first transport module and on which the carriage is able to move to and from the first transport module; a position detection unit that detects a position in a moving direction of the second transport module and outputs position information; a first control unit that controls motion of the carriage on the first transport module; a second control unit that controls motion of the carriage on the second transport module; a third control unit that controls motion of the second transport module; and a fourth control unit that controls the first to third control units. The fourth control unit corrects a position where the second transport module connects to the first transport module based on the position information.Type: GrantFiled: February 19, 2021Date of Patent: March 12, 2024Assignee: CANON KABUSHIKI KAISHIInventors: Hirohisa Ota, Takeshi Yamamoto, Satoru Deguchi, Takashi Shigemori, Kichinosuke Hirokawa, Ryota Okazaki

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

Patent number: 10951092Abstract: A carriage on which a workpiece is supplied and which is transported by a transport path has a reference member that is a reference for positioning of the workpiece. The carriage also has a fixing unit, whose motion is controlled by a control unit provided outside the carriage, that fixes the workpiece. The workpiece, which has been positioned in a first direction on the carriage and has not yet been fixed by the fixing unit, is pressed in a second direction against the reference member by a positioning unit, in which the second direction intersects with the first direction, and the workpiece is positioned on the carriage in the second direction.Type: GrantFiled: May 17, 2018Date of Patent: March 16, 2021Assignee: Canon Kabushiki KaishaInventors: Ryota Okazaki, Kichinosuke Hirokawa
