<P>PROBLEM TO BE SOLVED: To solve such a problem that image reading is stopped temporarily if the idle capacity reduces when the image data obtained by reading a document fed by an ADF is stored in a buffer, but when feeding of the document is stopped at a position in the document feed path of the ADF where behavior of the document becomes unstable, continuity cannot be maintained between the image data obtained before stopping the reading and the image data obtained after resuming the reading and, as a result, quality of the read image deteriorates. <P>SOLUTION: In a region where the behavior of a conveyed document becomes unstable, only conveyance of the document is performed and image reading by a sensor unit is not executed. The sensor unit is moved in the conveyance direction of document simultaneously with conveyance of the document. Consequently, conveyance of the document is prevented from stopping in the region where the behavior of the document becomes unstable. <P>COPYRIGHT: (C)2012,JPO&INPIT |
