Patent number: 10728407Abstract: An image reader includes: a document transport path through which a document to be read is transported; a transport roller that is provided on a lower side in the document transport path and is driven to apply a feed force to the document. The lower side of the document transport path upstream from the transport roller is at a position that is lower than a highest position of an outer circumferential surface of the transport roller and is formed on a lower guide surface guiding the document to the transport roller. A guiding unit is provided downstream from the lower guide surface and guides the document from the lower guide surface to a position on the outer circumferential surface of the transport roller, the position being higher than the lower guide surface.Type: GrantFiled: April 25, 2019Date of Patent: July 28, 2020Assignee: Seiko Epson CorporationInventors: Yoshikazu Nagai, Koichi Kikuchi
