Patent number: 11938931Abstract: A stop assist system for moving a moving body to a stop position and making the moving body stop at the stop position includes: an external environment recognizing unit that recognizes an external environment of the moving body; and a moving body control unit that executes a driving process to make the moving body travel to the stop position based on a recognition result of the external environment recognizing unit. The moving body control unit suspends the driving process when, while the moving body is traveling to the stop position, the moving body control unit determines, based on the recognition result, that there is an object within a range of a prescribed lateral threshold value on a lateral outside of the moving body and the object extends over a prescribed longitudinal threshold value or more along a travel direction within the range.Type: GrantFiled: February 18, 2022Date of Patent: March 26, 2024Assignee: HONDA MOTOR CO., LTD.Inventors: Junpei Noguchi, Gaku Shimamoto, Takuma Sekino, Tatsuro Fujiwara, Akiko Nakamura, Kazuya Kobayashi, Masafumi Sagara, Takeshi Sasajima

Patent number: 10471727Abstract: A configuration of a liquid ejecting head enables a stable, continuous ink supply with the off-carriage method, even if a force operates in the direction of joint needle insertion and removal. To this end, a joint opening that accepts insertion of a joint needle on a printing apparatus side is placed at a position closer to a joint face between an ejecting head and a sub tank unit than a positioning opening that engages with a positioning member on the printing apparatus side. Consequently, even if external force is produced due to coupling, the force exerted on the joint face that is a weak portion of an inkjet head may be minimized.Type: GrantFiled: May 13, 2016Date of Patent: November 12, 2019Assignee: Canon Kabushiki KaishaInventors: Chiaki Muraoka, Yukuo Yamaguchi, Hiromasa Amma, Takuya Iwano, Takeshi Sekino

Patent number: 8939527Abstract: An ink jet printing apparatus can suppress vibrations to a low level without local concentration of abrasion between a carriage and a guide shaft. The ink jet printing apparatus makes the carriage reciprocate along the guide shaft without ejecting ink, thus achieving a stirring operation in which the ink stored in an ink tank is stirred. At least one of a limited range in one direction, in which the stirring operation is performed, and a portion of the guide shaft that contacts the carriage when viewed from the one direction, is changeable.Type: GrantFiled: April 24, 2013Date of Patent: January 27, 2015Assignee: Canon Kabushiki KaishaInventors: Shimpei Shinohara, Takeshi Sekino

Patent number: 8936347Abstract: A driving apparatus includes an endless belt supported by a drive pulley configured to be driven by a motor and an idler pulley, and a moving member configured to be coupled to the endless belt and moved by driving the drive pulley by the motor, wherein a first limit value of electric power to be supplied to the motor when the moving member is moved in a first direction approaching the drive pulley is set larger than a second limit value of electric power to be supplied to the motor when the moving member is moved in a second direction approaching the idler pulley.Type: GrantFiled: October 18, 2012Date of Patent: January 20, 2015Assignee: Canon Kabushiki KaishaInventor: Takeshi Sekino

Patent number: 8789491Abstract: A cap sheet metal (and pivot sheet metal) is configured to be able to move linearly with a cap arm (and an arm stay) via engagement between an engagement hole and a fitting shaft. Furthermore, the cap sheet metal (and the pivot sheet metal) can move pivotally with respect to the cap arm (and the arm stay) using the fitting shaft, which engages with the engagement hole, as a pivotal shaft. Thus, even if, for example, the direction of biasing toward the applying roller deviates or a positional relationship with the applying roller deviates slightly, the liquid holding member moves and pivots in the bias direction depending on the deviation. As a result, the contacting pressure of a contacting portion on the applying roller can be made uniform.Type: GrantFiled: January 16, 2009Date of Patent: July 29, 2014Assignee: Canon Kabushiki KaishaInventors: Hideaki Nagahara, Tetsuyo Ohashi, Hiroshi Yoshino, Takeshi Sekino, Keisei Hakamata

Patent number: 8602538Abstract: A turning operation of a headset lever is completed, and a printing head can be detached from a carriage part. By the above described turning operation of the head set lever, a supply port insertion and extraction part connected via a link slides, a needle pipe of the supply port insertion and extraction part is brought into a state of being the farthest from the printing head, and a needle insertion and extraction lever is brought into state in which it moves under a case wall. Thereby, an operator cannot turn only the needle insertion and extraction lever when the head set lever is in an opened state. In this manner, when the headset lever is in the opened state, the operation of the needle insertion and extraction lever which is used for connection of the supply port insertion and extraction part to ink supply port is restricted.Type: GrantFiled: November 16, 2012Date of Patent: December 10, 2013Assignee: Canon Kabushiki KaishaInventors: Takeshi Sekino, Tetsuya Ishikawa
