Patent number: 10160601Abstract: A belt transporting device includes a belt; first and second adjustment members provided at two respective ends of a tension roller in a belt width direction orthogonal to a direction of rotation of the belt, the first and second adjustment members each being movable by receiving a force from the belt; and a link member that interlocks the movement of the first adjustment member and the movement of the second adjustment member. If the belt is laterally shifted in the belt width direction, one of the first and second adjustment members moves by receiving a force from the belt while the other is moved by the link member such that the tension roller is tilted with respect to a driving roller.Type: GrantFiled: August 22, 2017Date of Patent: December 25, 2018Assignee: Canon Kabushiki KaishaInventors: Takeo Kawanami, Yoshihiro Ito, Kenji Watanabe, Daigo Yamauchi, Fumiya Sawashima, Osamu Sasaoka, Yoichiro Iizuka, Hiromi Fujinaka, Takugo Kasaishi
