Claim Text:
1. An image reading apparatus, comprising: a conveyance unit configured to convey a document along a conveyance path; a first reading unit configured to read images of a top face of the document conveyed by the conveyance unit and a second reading unit configured to read images of a back face of the document conveyed by the conveyance unit, the second reading unit being positioned on a downstream side of the first reading unit in a conveying direction of the document; a storage control unit configured to store image data of the images read by the first reading unit and the second reading unit in a memory; and a control unit configured to perform an interruption processing for interrupting the reading of the image by the first reading unit and the second reading unit, wherein if a free capacity of the memory is smaller than the capacity required for the first reading unit and the second reading unit to read images, the control unit performs the interruption processing at a timing in which the conveyance of the document whose image on the top face has been read at least partially by the first reading unit is stopped in front of the second reading unit, such that the document has reached the first reading unit and has not reached the second reading unit.
