Patent ID: 8537432

Claim:
An image-reader comprising: a conveyance unit that is configured to sequentially convey a plurality of document sheets at a predetermined interval along a conveying path, each document sheet including a first surface and a second surface; a first reading unit that is configured to read an image on a first surface of a document sheet being conveyed on the conveying path and output first image data corresponding to the read image of the first surface; a second reading unit disposed on the conveying path apart from the first image reading unit, the second image reading unit being configured to read an image on a second surface of the document sheet being conveyed on the conveying path and output second image data corresponding to the read image of the second surface; a storing unit that is configured to store the first image data output from the first reading unit and the second image data output from the second reading unit; an image process circuit that is configured to acquire at least one of a part of the first image data and a part of the second image data from the storing unit, and to perform an image process on the image data acquired from the storing unit, the image process circuit having a first setting corresponding to setting of the image process circuit for the first surface and a second setting corresponding to setting of the image process for the second surface; and an initialization instruction unit, wherein when the image process circuit finishes performing the image process on the first image data, the initialization instruction unit instructs initializing the first setting corresponding to the first image data, and when the image process circuit finishes performing the image process on the second image data, the initialization instruction unit instructs initializing the second setting corresponding to the second image data, wherein when the initialization instruction unit instructs initializing the first setting, the image process circuit initializes the first setting and when the initialization instruction unit instructs initializing the second setting, the image process circuit initializes the second setting.
