An information processing device to generate data pertaining to a document from electronic paper which has a display section to display and retain the document, and a memory to store document identification data, includes a document data storage unit which stores document electronic data, a communication unit which acquires document identification data from the electronic paper, a reading unit which scans the display section, a data extraction unit which extracts from the document data storage unit document electronic data corresponding to the document identification data, a difference processing unit which extracts a note image appended on a surface of the display section according to a difference between an image from the extracted document electronic data and an image of the scanned display section, and a data generation unit which associates data of the extracted appendix image and the extracted document electronic data, thereby generates data pertaining to the document.

Information processing device and method, and data communication system for acquiring document data from electronic paper

An image forming apparatus writes an image to a display recording medium at a write position. The image forming apparatus includes an insertion slot, a transport unit, an image light emitting device and a separating/contacting unit. The display recording medium is inserted into the insertion slot. The transport unit transports the display recording medium inserted, to/from the write position. The image light emitting device includes an emitting surface that emits two-dimensional image light for irradiating a photoconductive layer of the display recording medium at the write position. The separating/contacting unit brings the emitting surface separate from a display recording medium surface when the display recording medium is not opposed to the image light emitting device, while the transport unit transports the display recording medium. The separating/contacting unit brings the emitting surface into proximity to the display recording medium surface when the display recording medium is at the write position.

An electronic paper system includes: electronic paper having a display unit that can display and retain an image in a no-power state; image generation means for generating a displaying image by combining a scale-down image of at least a part of a document and an image of at least part of related information of the document; and write means for writing the generated displaying image into the display unit of the electronic paper so that the display unit displays and retains the generated displaying image.

A medium writing apparatus obtains information to be written onto a recording medium, converts the information into a suitable writable format, and then writes the converted information onto the recording medium. An ID obtaining section obtains a medium ID from the recording medium, or through an input by the user. The medium ID and information indicating the place of the written information are sent to a server, and then stored as index information correlating them with each other. When the information written onto the recording medium is to be used at a later timing, the medium ID is identified, and the index information is obtained from the server. Therefore, the original information can be obtained so as to be easily reprocessed or reused.

System for writing information and method of writing information

An IC coin includes an antenna coil for transmitting and receiving value information to and from a recording medium processing device, an RF-ID tag for recording the value information, an image display medium to or from which an image is written or deleted by applying voltage, an anode terminal exposed on an external surface of the IC coin to input voltage applied to the image display medium by connecting with an external terminal, and cathode terminals. In the IC coin having this structure, voltage for writing or deleting an image can be inputted from outside and an image can be written or deleted to or from the IC coin.

A multi-level optical writer for writing an image by illumination to an optical-write-type recording medium laid with a display layer having a memory nature and a photoconductive layer, the optical writer includes: a holding portion holding the optical-write-type recording medium; and a write section for writing a multi-level image to the display layer by illuminating, to the photoconductive layer, image light having optical dots different in size in accordance with a gray level.

Multi-level optical writer

An information management system which enables analysis on basis of a processing history of content with use of a portable displaying-and-recording medium, includes a log recording function of managing user identification data to specify a user who owns the portable displaying-and-recording medium and content identification data to specify content, and recording the user identification data and the content identification data in an associated manner after the user performs processing of the content. Preferably, the portable displaying-and-recording medium records/retains data in a state where content is displayed and is capable of rewriting the content.

Information management system and information management method

A printed-matter issuing client takes out contents from a contents management server, and prints the contents on a printing recording part, while at the same time records ID information indicative of a storage location of the contents into an IC chip integrated into the printing recording part. A printed-matter verifying client reads out an image to be verified on a printing surface of a printing recording part, by an information acquiring part, and acquires ID information from the IC chip. The printed-matter verifying client takes out contents from the contents management server according to the ID information, and verifies it with the image on the print surface, and it judges whether the printing recording part is true or false on the basis of the verifying result.

While names of data and icons are displayed on a selection-purpose display medium, a user selects data. Since the selection-purpose display medium is constituted by such a display medium capable of displaying a moving picture, operability by the user may be guaranteed. The content of the data which is selected by the selection-purpose display medium is displayed on a contents-display-purpose display medium. Since the contents-display-purpose display medium is constituted by a display medium having a memory characteristic, power consumption may be reduced, and this display medium having the memory characteristic may be dismounted. Since the display screen for the selection operation and the display screen for the contents display operation are separately provided, the user can perform the work by viewing the content of the data in correspondence with the data, so that the work efficiency can be increased.

The present invention provides an image-forming device that can record an image onto a rewritable image recording medium. Prior to recording a predetermined image, the medium is set and a test image for measuring the density is recorded thereon. When the density is determined to be within an allowable range, the predetermined image is recorded under certain image recording conditions and then discharged to a discharging tray. However, should the density be outside the allowable range, the conditions are changed and another test image is recorded to the medium. If after repeated density measurements the density is not within an allowable range, the device determines that the medium is defective and discharges it to an error tray.

Image-forming device and method

A display and record medium includes a digital information record section, which is implemented as an IC memory and can record record information in noncontact, and an information display section implemented as a liquid crystal display medium of light write type into which display information can be written. A digital information rewrite section of an information writer communicates with the digital information record section of the display and record medium by electromagnetic waves to rewrite record information as required. A display information rewrite section of the information writer irradiates an optical pattern to the information display section of the display and record medium to rewrite display information. It is possible to rewrite both digital information and display information concurrently in noncontact.
