Patent number: 7924238Abstract: 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.Type: GrantFiled: November 2, 2005Date of Patent: April 12, 2011Assignee: Fuji Xerox Co., Ltd.Inventors: Yasunori Saito, Ikutaroh Nagatsuka, Tsutomu Ishii, Minoru Koshimizu

Patent number: 7857203Abstract: 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.Type: GrantFiled: June 12, 2009Date of Patent: December 28, 2010Assignee: Fuji Xerox Co., Ltd.Inventors: Ikutaroh Nagatsuka, Yasunori Saito, Minoru Koshimizu, Daisuke Tsuda, Tsunemasa Mita, Tsutomu Ishii, Kiyoshi Shigehiro, Takeshi Matsunaga, Takeo Kakinuma, Yoshinori Machida, Yasufumi Suwabe, Hiroshi Arisawa, Yasunari Nishikata, Haruo Harada

Printed-matter issuing managing system, printed-matter verifying device and contents managing device
Patent number: 7455216Abstract: 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.Type: GrantFiled: December 16, 2002Date of Patent: November 25, 2008Assignee: Fuji Xerox Co., Ltd.Inventor: Ikutaroh Nagatsuka -
Publication number: 20070229393Abstract: A writing device constituting an electronic book includes a connector to which electronic papers are detachably connected. The number of connected sheets of electronic paper is recognized, and is output to a host computer. In the host computer, display data is output on the basis of the number of electronic papers, and the display data is written in the electronic papers by a write control unit. When a change of connections of the electronic papers is detected by the detection unit, a part of images displayed on the electronic papers is rewritten depending on the detected connection states of the electronic papers by which optimum images on the electronic papers are displayed even if an arbitrary electronic paper is attached or detached.Type: ApplicationFiled: May 29, 2007Publication date: October 4, 2007Applicant: FUJI XEROX CO., LTD.Inventors: Tsutomu Ishii, Tsunemasa Mita, Takeshi Matsunaga, Hiroshi Arisawa, Ikutaroh Nagatsuka, Takeo Kakinuma, Yasunari Nishikata, Haruo Harada, Kiyoshi Shigehiro, Yasufumi Suwabe, Yoshinori Machida

Patent number: 7225403Abstract: 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.Type: GrantFiled: September 3, 2003Date of Patent: May 29, 2007Assignee: Fuji Xerox Co., Ltd.Inventors: Ikutaroh Nagatsuka, Tsunemasa Mita, Daisuke Tsuda, Minoru Koshimizu, Tsutomu Ishii, Yasunori Saito

Patent number: 7219973Abstract: 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.Type: GrantFiled: July 29, 2003Date of Patent: May 22, 2007Assignee: Fuji Xerox Co., Ltd.Inventors: Ikutaroh Nagatsuka, Tsunemasa Mita, Daisuke Tsuda, Minoru Koshimizu, Yasunori Saito, Tsutomu Ishii
