Scanning apparatus and method for identifying group of papers comprising of single scan job and apparatus and method for detecting folded corners of papers

The scanning device and the identification and processing method for processing to identify the document of a plurality number of sheets that make up the same document information is disclosed. Scanning device according to one aspect of the present invention includes the image information reading unit, a video-information storing unit, a scanning identification section, an image information processing unit and the interface unit. Image information reading unit reads the image information of the document to be supplied as from the paper feed. Identification scanning unit to detect the identification information which identifies the document in a group constituting a single document information (hereinafter referred to as "single scanning") made up of a document of a plurality of pages of the given document, the image information processing unit from the identification unit scan operation receiving the identification information, and processes the image information of the document in a group making up a single scanning operation into a single file. Interface unit communicates with a predetermined network for transmitting the output of the image information processing unit to an external device. Scanning identifying unit determines the identification information represented by the state in which the edge of the folded article ear folding (folded corner) presence or absence may identify documents of a group constituting the single scanning. At the same time loaded in the paper supply for a plurality of sheets of document to configure the plurality of scanning by the scanning device and method according to the present invention, even if by using the easy identification scanning device that automatically separates the scanning of the document, each scanning each user convenience is increased significantly, so create a separate file.
