Abstract: A 2-dimensional code reading apparatus includes a code position detector receiving an input image that is formed by optically reading 2-dimensional codes, and extracting a 2-dimensional codes from the input image. A data acquisition unit acquires identification information of a document page and positional information of the 2-dimensional codes on the document page, from the 2-dimensional codes. A data decoder performs decoding of the identification information and the positional information. The code position detector is provided with a code frame detector detecting a code frame which defines a fixed region of the 2-dimensional codes, and determining a dot of a target pixel as being a corner dot of the code frame.

Abstract: A paper identification information management system includes a client apparatus that handles a sheet of paper bearing prescribed information, and a management server connected to the client apparatus via a network to comprehensively manage information about the paper handled in the client apparatus. The client apparatus transmits a paper ID request and document information to the management server via the network when carrying out a printing operation. Based on the paper ID request and the document information, the management server assigns a paper ID to each sheet of paper handled by the client apparatus. The management server then transmits the paper IDs to the client apparatus, and simultaneously, records the assigned paper IDs in association with the document information.

Abstract: A small-sized pen-shaped input apparatus precisely detects handwriting input. The apparatus compensates for the effects of the inclination of the pen-shaped input apparatus. An initial inclination angle calculating section calculates the initial value of the inclination angle of a pen shaft in a gravity coordinate system. The inclination angle variation calculating section calculates a variation value of the inclination angle of the pen shaft. A handwriting inclination angle calculating section calculates the inclination angle of the pen shaft when writing. A coordinates conversion calculating section converts the coordinate system of the acceleration from the pen shaft coordinate system to the gravity coordinate system. A movement amount calculating section calculates the movement direction and the movement distance of the pen's tip end. Finally, a handwriting detecting section detects a state of handwriting or non-handwriting.
