Patent number: 11979531Abstract: A scanner includes an apparatus main body, a stand, and a switching mechanism. The apparatus main body includes a transport unit that transports a document along a transport path, and a reading unit that reads an image of the document. The stand supports the apparatus main body. The switching mechanism switches the posture of the apparatus main body with respect to the stand so that the transport path extends along an intersecting direction intersecting an installation surface. The switching mechanism includes a switching motor that imparts a driving force to the apparatus main body when switching the posture. The switching motor is located inside the apparatus main body on the lower side of the transport path in the vertical direction.Type: GrantFiled: September 30, 2022Date of Patent: May 7, 2024Assignee: SEIKO EPSON CORPORATIONInventors: Noriyuki Koyanagi, Keiichiro Fukumasu

Publication number: 20230344948Abstract: An image reading apparatus includes a transport unit which transports a document, and reading units which read an image of the document which is transported. It is assumed that an operation of reading an image when specific setting information is not input to a control device of the image reading apparatus is set to a first reading mode, and an operation of reading an image when specific setting information is input to the control device is set to a second reading mode. In this case, in the second reading mode, image data of an image with a resolution which is equal to that in the first reading mode is generated, while causing the reading units to read an image from a document which is transported by the transport device at a lower speed than that in the first reading mode.Type: ApplicationFiled: June 28, 2023Publication date: October 26, 2023Inventors: Noriyuki KOYANAGI, Tokujiro OKUNO

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

Patent number: 11445079Abstract: When a transport section transports be a media, a controller of an image reading apparatus determines the lengths of the media in the transport direction, based on detection results of a medium detector. When determining that a length of a medium is equal to or more than a threshold and then determining that a length of a subsequent medium is equal to or more than the threshold, the controller decreases an ejection speed of the subsequent medium to a second speed by the transport section. When determining that a length of a medium is equal to or more than the threshold and then determining that a length of a subsequent medium is less than the threshold, the controller decreases the ejection speed from the first speed to a third speed that is lower than the second speed by the transport section.Type: GrantFiled: September 9, 2021Date of Patent: September 13, 2022Assignee: SEIKO EPSON CORPORATIONInventors: Noriyuki Koyanagi, Kosuke Nomoto, Akira Anami, Naoki Sakamoto, Wataru Beppu
