Patent number: 11785155Abstract: An apparatus body of an image reading apparatus is turnably provided to a body supporting portion. The apparatus body is turned so as to be switchable between a first posture and a second posture that forms an angle between a reading transportation path and a mounting surface being smaller than the corresponding angle formed in the first posture. A transportation path switching unit couples the reading transportation path to a reverse transportation path when the apparatus body takes the first posture, and couples the reading transportation path to a non-reverse transportation path when the apparatus body takes the second posture.Type: GrantFiled: September 27, 2022Date of Patent: October 10, 2023Assignee: Seiko Epson CorporationInventors: Noriyuki Koyanagi, Keiichiro Fukumasu, Ryoichi Shuto, Yoichiro Nishimura

Publication number: 20230094561Abstract: A scanner includes: a first transport roller pair that transports a material; a reader that reads the material; a second transport roller pair that transports the material; a transport motor; and a pressing section. The transport motor 50 rotates both the rollers of the first transport roller pair and both the rollers of the second transport roller pair. The pressing section can vary a first pressing force generated in the first transport roller pair and a second pressing force generated in the second transport roller pair. The pressing section varies the second pressing force in such a way that the second pressing force when the first transport roller pair transports the material but the second transport roller pair does not transport the material becomes lower than the second pressing force when neither the first transport roller pair nor the second transport roller pair transports the material.Type: ApplicationFiled: September 29, 2022Publication date: March 30, 2023Inventor: Yoichiro NISHIMURA
