An image reading apparatus includes a document tray, a detection unit, a sheet feeding unit, a conveyance unit, a reading unit, a sheet discharge unit, a sheet discharge tray, and a control unit configured to stop feeding of the document by the sheet feeding unit in a case where the detection unit detects that there is no document present on the document tray. The control unit is configured to execute a first mode and a second mode, the first mode being a mode in which the sheet feeding unit stops feeding of documents in a case where the number of documents having been discharged continuously by the sheet discharge unit has reached a predetermined number of sheets, and the second mode being a mode in which the sheet feeding unit continues feeding of the documents regardless of the number of documents having been discharged continuously by the sheet discharge unit.

An image forming apparatus (100) extracts from first image data (11) second image data (12), which is image data of a document, and accepts operation for selecting either a first preview image (71) corresponding to the first image data (11) or a second preview image (72) corresponding to the second image data (12). The image forming apparatus (100) outputs, when the first preview image (71) is selected, the first image data (11) and, when the second preview image (72) is selected, the second image data (12).

Examples disclosed herein relate to identifying a plurality of content areas of a document to be scanned, classifying each of the plurality of content areas into a content type, determining a minimum scanning resolution to maintain readability for each of the plurality of content areas according to the classified content type, and performing a scan of the document to a digital file, wherein each of the plurality of content areas is scanned at least at the determined minimum scanning resolution to maintain readability of the respective content area.

A method for selectively scanning, by a scanning unit including a processor and a memory, a plurality of pages from a document includes the step of receiving, by the scanning unit associated with a Multi-Function Printer (MFP), a user input indicating a plurality of pages to be scanned from the document, the user input including one of a page range or a page skip interval. The method also includes processing, by the scanning unit, the user input for selectively scanning the plurality of pages from the document.

An image reading apparatus includes a supporting portion, a feeding portion, a curved conveyance path, a conveyance unit, an image reading unit, a driving source, an output pulley, an input pulley, a first pulley, a second pulley, a driving belt, and a transmission belt. The image reading unit is configured to read an image on a first surface at a location between the first driving roller and the second driving roller in a sheet conveyance direction. The output pulley is fixed to an output shaft of the driving source. The input pulley is fixed to the second driving roller. The first pulley is fixed to the first driving roller. The second pulley is fixed to the second driving roller. The driving belt is wound around the output pulley and the input pulley. The transmission belt is wound around the first pulley and the second pulley.

A size determination method for a document processing device is provided. The document processing device includes an automatic document feeding module. The automatic document feeding module includes a support tray, an entrance and a detecting module. The detecting module includes a front-row detector and plural rear-row detectors. The size determination method includes following steps. Firstly, a document with plural originals is placed on the support tray and inserted into the entrance. Then, a selected original of the document is transported. When the selected original is detected by the front-row detector, the plural rear-row detectors are powered on. The selected original is continuously transported, and the plural rear-row detectors are operated in a detection mode. Then, a size of the selected original is determined according to detection results of the plural rear-row detectors and a transfer time of the selected original.

A method and system for managing storage of scanned document in Multi-Function Printer (MFP). The method comprises receiving document and request for scanning the document. Further, the method comprises determining options for storing the document, based on properties for scanning the document and current capacity of storage unit. Each of the options indicates image file format for the document and at least one of color mode or image resolution for the document. Furthermore, the method comprises providing the options for receiving selection from user. Thereafter, the method comprises storing, the scanned version of the document in the storage unit, based on option selected by the user. The method and system ensures that the scanning of the document is performed even when the sufficient capacity is not available in the MFP.

An image reading apparatus includes an output tray that receives a medium which is output thereon; an output roller pair that outputs the medium onto the output tray; an output-tray posture switching portion that switches a posture of the output tray with respect to the apparatus body; and an output-direction switching portion that switches an output direction of the medium by using the output roller pair. The output roller pair includes an output driving roller, and an output driven roller that nips the medium between the output driven roller and the output driving roller and that follows the rotation of the output driving roller. The output-direction switching portion switches the output direction of the medium by displacing a rotation center of the output driven roller around a rotation center of the output driving roller.
