The disclosure discloses methods and systems for handling content of a document based on one or more identifiers. The method includes receiving the document having content marked using one or more starting identifiers and corresponding one or more ending identifiers, the content marked between each starting identifier and corresponding ending identifier indicates content for one of: extraction, deletion, replacement and sharing, the content in the document is marked using braille symbols. The content is marked using an erasable marking device without affecting the document. A selection of a function to be performed on the marked content is received. The document is scanned to generate a scanned document. The scanned document is analyzed to identify the one or more starting identifiers and the one or more ending identifiers. Based on the selection of the function to be performed on the marked content, perform one of: extraction, deletion, replacement and sharing.

In a multifunction peripheral according to the present invention, a sheet selection screen for selecting a sheet that is the output destination is presented. A “check sheet size” button is provided on the sheet selection screen. When the “check sheet size” button is operated, an optimal sheet size identification function is started, and a document size identification process including pre-scan is performed. Accordingly, the size of a document is identified. Further, an optimal sheet size identification process is performed. Thus, the optimal sheet size, which is a suitable sheet size corresponding to the size of the document, is identified.

A background image is acquired by imaging an opening plate as a background of an original document in a state where the original document is not arranged. Next, an original document including background image is acquired by imaging the same range as the background image in a state where the original document is arranged on an upper surface of the opening plate. Next, a difference image is generated by subtracting the background image from the original document including background image. In addition, an inverse difference image is generated by subtracting the original document including background image from the background image. A region of the original document is detected based on the difference image and the inverse difference image.

A medium feeding device includes: a placement unit on which a medium is placed; a pair of edge guides that is provided at the placement unit such that the edge guides are movable in a medium width direction to guide edges of the medium in the medium width direction that is a direction intersecting a medium feeding direction; feeding rollers that feed the medium placed on the placement unit; a path state detection section that detects a detection value in accordance with a state of the medium feeding path; a guide position detection section that detects positions of the edge guides; and a control section that determines whether or not the detection value detected by the path state detection section has exceeded a threshold value.

An information processing apparatus includes a receiving unit that receives printing data and a switching unit that performs switching between a second rotation mode and a first rotation mode. The first rotation mode is a mode in which an orientation in the printing data undergoes rotation through an angle decided in accordance with an analysis of content of the printing data. The second rotation mode is a mode in which if an angle for an output size in the printing data is stored in a memory, the angle is read out from the memory, and the orientation in the printing data undergoes the rotation.

A reading device including a position reference member having a reference pattern having a line extending along a first direction of the position reference member, the position reference member movable in a second direction orthogonal to the first direction; a reader including a plurality of sensor chips arranged along the first direction, each of the sensor chips having a length defined by a plurality of pixels; and circuitry. The circuitry is configured to detect the reference pattern of the position reference member using the reader; determine coordinates of at least two sensor chips in the second direction, based on the detected reference pattern of the position reference member; and correct a position of a reading target in the second direction based on the coordinates determined for the at least two sensor chips of the reader in the second direction.

An image forming apparatus includes an image reading part, an image forming part, and a sheet feeding cartridge. The image reading part reads a document and obtains image data of the document. The image forming part forms an image on a sheet on the basis of the image data. The sheet feeding cartridge stores several kinds of the sheets. In a case where predetermined sheet feeding information is applied on the document, the sheet feeding information is read on the basis of the image data. Conveying of the sheet is controlled so as to convey the sheet corresponding to the sheet feeding information from the sheet feeding cartridge to the image forming part and, on the other hand, to eject the sheet not corresponding to the sheet feeding information from the sheet feeding cartridge without passing through the image forming part.

A printing apparatus capable of adding number information differing from copy set to copy set, to a printing target image includes a judging unit configured to judge whether to add user information indicating a current user to a printing target image, and a determination unit configured to determine a position to which the number information is to be added, based on a result of the judgment performed by the judging unit.

There is provided with a method of controlling an image processing apparatus. The method includes accepting a predetermined instruction for adding a predetermined mark to a first image which is being displayed. The method includes, based on at least one of a non-printing area corresponding to an area on a recording medium where printing is not to be performed and a second image being positioned at the predetermined location when the predetermined instruction is accepted, causing at least one of the first image and the second image to move. The at least one, that was positioned at the predetermined location when the predetermined instruction was accepted, of the non-printing area and the second image is not positioned at the predetermined location after at least one of the first image and the second image has been moved.

An image reading device includes a marking part that applies a predetermined mark to a margin of a rear end of a document having passed through an image reading position, a mark erasing part that erases the predetermined mark when the document is discharged from a sheet discharge port, and an image data processing unit that determines whether the predetermined mark exists in image data of a document image read by an image reading unit and erases the image data of the document image when it is determined that the predetermined mark exists.
