A pen includes a first speaker that outputs a first signal and a second speaker that outputs a second signal. The first and second speakers are located away from a tip of the pen at respectively different locations. The second signal is delayed with respect to the first signal by a time shorter than a cycle of the first signal. An interpolation time is set between the times of generation of the first and second signals. Interpolated positions of the first and second speakers at the interpolation time are estimated, and position of the tip of the pen is calculated from the interpolated positions of the first and second speakers.

Coordinate detecting device, writing instrument, and coordinate inputting system

A document processing system is disclosed that is capable of processing both fixed-format and unfixed-format hand written paper documents. The document processing system includes an encoding unit that encodes a sheet ID for identifying a hand written first document on a sheet to generate a coded sheet ID; a decoding unit that decodes the coded sheet ID; a document-sheet ID association unit that associates the sheet ID with a document ID assigned to a computerized second document; a printing unit that acquires the sheet ID and prints the coded sheet ID on the first document; a sheet ID management unit that manages the sheet ID; an information acquisition unit that acquires the sheet ID decoded by the decoding unit, and hand-written data from the first document on which the coded sheet ID is printed; and a process-sheet ID association unit that associates the sheet ID with a process ID of a process for processing the hand-written data acquired by the information acquisition unit.

Document processing system

An electronic document creating apparatus includes a document information obtaining device that obtains and inputs document identification information put on a sheet document. The document identification information specifies an electronic document stored in a folder. The electronic document serves as an output source of the sheet document. An electronic document extraction device is provided to extract an electronic document based on the document identification information. A new document creation device is provided to create a new electronic document by combining at least two electronic documents extracted by the electronic document extraction device. The new electronic document is stored in a folder.

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.

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.

Paper identification information management system

An information processing apparatus is constructed to include a plurality of information recording media respectively having a generally paper shape with an image display surface for displaying various information, a holding part which holds a holding portion of each of the information recording media which are stacked, an input part for accepting an input of various information by handwriting on an arbitrary one of the information recording media, a recognizing part for recognizing the identification information recorded on the arbitrary information recording medium, a storing part for storing the various information accepted by the input part and the identification information recognized by the recognizing part in an information storage medium by linking corresponding various information and identification information, and an output part for outputting the various information stored in the information storage medium with respect to a storage which stores various information at storage locations specified in advance depending on the identification information.

An imaging method includes the steps of (a) determining whether an object on which an image is to be formed is an information display medium on which a code is formed with an imaging material formed of a near infrared absorbing pigment, and (b) forming the image on the object by a printer engine with an imaging material formed of a pigment absorbing no or little light in a near infrared spectral region if the step (a) determines that the object is the information display medium.

Imaging method, imaging apparatus, and image information management system

An erasable recording material including a substrate, and an erasable recording layer which is formed overlying the substrate and in which image information is repeatedly recorded and erased, and optionally includes an undercoat layer formed between the substrate and the recording layer, a protective layer formed overlying the recording layer and an intermediate layer formed between the recording layer and the protective layer, wherein the erasable recording material further includes one or more markers which are used for inputting image information additionally written on the recording material. An information recording system and method are also provided in which additional information written on the erasable recording material, in which image information is previously recorded, is incorporated to the previously recorded image information.

An electronic blackboard system with a PDP for displaying characters and images. A touch input device with a touch panel surface is provided on the front surface of the PDP. A printer outputs image data onto recording paper. A computer provides control over displays on the PDP as well over the printing operations of the printer according to the input from the touch input device. A frame unit has a board section for holding a display surface and a write-in surface of the electronic blackboard at a specified height. A printer accommodating section accommodates the printer and a computer accommodating section accommodates the computer therein. The computer accommodating section, the printer accommodating section and the board section are arranged in the vertical direction starting from the bottom.
