Abstract: An image scanning device includes a scanning specifying unit, a first transportation path, a second transportation path, a path switching unit, and a document detection unit. The scanning specifying unit specifies as a scanning method of a document either a double sided scanning or a single sided scanning. The first transportation path is a transportation path for double sided scanning to scan a first surface and a second surface of the document in order. The second transportation path is a transportation path for single sided scanning, which is shorter than the first transportation path, to scan the second surface of the document. The path switching unit selects either the first transportation path or the second transportation path based on the specified scanning method. The document detection unit detects the document with the first surface scanned and the second surface not scanned when the double sided scanning is interrupted. The path switching unit selects the second transportation path for the transportation path of the first document in the resumed double sided scanning based on a detection result of the document detection unit.

Abstract: In an image scanning apparatus, documents on a document tray are transferred one by one, and an upper surface height of the documents is lowered to turn off a height detection sensor. Different kinds of control modes are performed according to a document scanning mode. In an image-quality-priority scanning mode, a transfer unit suspends transfer of the document, the document tray is elevated until the upper surface height reaches a target height that is higher by a predetermined distance after the height detection sensor is turned on, and the transfer unit resumes the transfer of the document. In a speed-priority scanning mode, while the transfer of the document is continued by the transfer unit, the document tray is elevated until the document tray reaches the target height.

Abstract: An image scanning device accepts an instruction to scan a double-sided document and scans a plurality of double-sided documents with respect to each page to produce image data. Image data is eliminated when a page is determined as being solid colored from the image data produced by the scanning section. Image data other than the eliminated image data is transmitted to the outside. When an instruction to scan a double-sided document is received from the outside and accepted, elimination of image data is prohibited.

Abstract: In an image scanning apparatus, when documents on a document tray are sequentially transferred, different control steps are performed according to a scanning speed when an upper surface height of the documents is lowered thereby turning off a height detection sensor. In a low scanning speed, the document tray is elevated one time until the upper surface height becomes a target height which is higher by a predetermined distance since a height detection sensor is turned on at an inter-transfer time between completion of document transfer and start of a subsequent document transfer. In an intermediate scanning speed, the document tray is elevated little by little in each transfer of one document at the inter-transfer time until the upper surface height reaches the target height. In a fast scanning speed, the transfer of the document is tentatively interrupted, the document tray is elevated one time until the upper surface height reaches the target height, and the transfer of the document is resumed.

Abstract: In an image scanning apparatus, when documents on a document tray are sequentially transferred, different control steps are performed according to a scanning speed when an upper surface height of the documents is lowered thereby turning off a height detection sensor. In a first control mode, which is not a high speed scanning, the document tray is elevated little by little during an inter-transfer time between each time one document is transferred until the upper surface height reaches a target height that is higher by a predetermined distance since the height detection sensor is turned on. In a second control mode, in which high speed scanning is performed, the document tray is elevated little by little during the inter-transfer time each time the one document is transferred until the upper surface height reaches a height that is higher by a predetermined distance than a height at a time when the height detection sensor is turned off.
