Patent number: 9118830Abstract: A printer includes a scanner unit which reads a document; a recording portion which records information read by the scanner unit; and a tilt panel which constitutes the scanner unit and an operation portion of the recording portion. A printer executes a division reading mode which obtains image information of the entire document by linking image information obtained via a plurality of times of a document reading operation, with respect to the document of which the size is greater than the size of the document reading area. The image information of the entire document can be obtained by sequentially linking a predetermined image position of an ending position side of an image obtained by a first document reading operation and a predetermined image position of an initiating position side of an image obtained by the following document reading operation, in a linking direction of the image.Type: GrantFiled: July 30, 2014Date of Patent: August 25, 2015Assignee: Seiko Epson CorporationInventors: Yoshiyuki Okazawa, Hidetake Nishizawa, Yoshisada Aoki
