    摘要： A document transporting device (30) serves as a platen cover to expose and cover platens (21A,21B). A document holder (5) is mounted on a predetermined mounting portion of the device (30). A lateral end of the document holder (5) is withdrawn from a predetermined position where the end is located, so that a document transport path (R) is exposed through an area in which the document holder (5) has been withdrawn. The document transport path (R) is exposed to the left or the right with respect to the front of the device (30).

    摘要： An ADF defines a document feed path inclined downwardly from above a document platen. Feeding means is disposed downstream of a first reading glass plate and accommodated in a downwardly protruding portion. The protruding portion is accommodated in a dent portion of an image reading unit. The feeding means includes a feeding guide having a downstream side serving as a supporting point and an upstream side supported at the supporting point for pivotal movement about an axis parallel with the widthwise direction of the document feed path. The feeding guide is exposed out of the feeding means on the document platen side. When the ADS is closed while a document is in a state of extending off the document platen onto the dent portion, the upstream side of the feeding guide is pressed up by the document to move into an upper position.

    摘要： A storage area where compressed data is stored is divided into a plurality of divided areas having a data length of Ls. Each divided area is divided into two areas, a first area having a data length of Ld and a second area having a data length of La. A plurality of first areas are gathered starting from the upper address to the lower address, whereby a memory area for compressed image data is composed. A plurality of second areas are gathered starting from the upper address to the lower address, whereby a memory area for compressed attribute data is composed. Compressed image data is sequentially written starting from the upper address to the lower address of the memory area for compressed image data. Compressed attribute data is sequentially written starting from the upper address to the lower address of the memory area for compressed attribute data.

    摘要： Reference images on the respective surfaces of a reference document transported on a transportation path are read out by a first image reading section and a second image reading section, respectively. As a result a first reference readout image and a second reference readout image are acquired. in accordance with the difference between the changes in the sub-scanning direction in the first reference readout image and the changes in the sub-scanning direction in the second reference readout image, the reading cycle of the first image reading section X1 and the reading cycle of the second image reading section X2 are set. This makes it possible to equalize the magnifications of the respective images on the front and back sides of the document, even if the speeds of the document at the times of passing through readout positions for the front and back sides change over time, on account of the wear of a transportation roller.
