Patent number: 6341906Abstract: A tape cassette is set in a cassette accommodating section of a tape printer. A magnetically affixable printing tape is fed out from a holding reel along with an ink ribbon having a non-magnetic ink layer formed thereon across a cut in the tape cassette and conveyed through between a thermal head and a platen roller while being pressed by those elements. The printing tape comprises a printing layer and a magnetic layer pasted to the printing layer. The magnetic layer is magnetized such that S and N poles are alternately arranged longitudinally of the tape to thereby prevent turns of the tape roll from shifting widthwise. The magnetic layer has a coated fluorine layer formed thereon or has wrinkles formed thereon to thereby prevent blocking from occurring on a printing face of the tape due to its winding. Thus, the printing tape is conveyed in a correct attitude to enable a high quality image to be printed thereon.Type: GrantFiled: September 14, 1999Date of Patent: January 29, 2002Assignee: Casio Computer Co., Ltd.Inventors: Kenji Kobayashi, Kenzo Ito, Kenji Igarashi, Masayuki Ikeda, Kensaku Takeuchi, Kenji Suyama, Satoshi Kimura, Koji Deguchi

Patent number: 6324350Abstract: An identification label is affixed on a top surface of an image forming unit which is detachably installed in a main component of an image forming apparatus. The identification label is made of a thermosensitive paper on which a trademark logo is printed. A logo reader in the main component reads a pattern of the logo mark on the identification label. A control unit compares the read logo pattern with a previously stored pattern to discriminate whether the read logo mark is genuine or not. If the identification label has the genuine logo mark, the control unit executes printing. If the identification label has an irregular logo mark, printing is abandoned and an error message is displayed. When a genuine image forming unit is exhausted, the control unit controls a heating device to apply heat to the identification label in order to wholly or partially discolor the identification label so that the logo mark is transformed to unreadable one. That unit will be regarded as an irregular one thereafter.Type: GrantFiled: December 13, 1999Date of Patent: November 27, 2001Assignees: Casio Computer Co., Ltd., Casio Electronics Manufacturing Co., Ltd.Inventors: Kenzo Ito, Kazutami Noguchi, Kenji Kobayashi, Masayuki Ikeda, Kenji Igarashi

Patent number: 6304626Abstract: A two-dimensional array type of X-ray detector, incorporated into an X-ray computerized tomography apparatus, has a plurality of X-ray detecting elements arranged in the X and Y directions for detecting incident X-rays into electric signals. A mask is placed on the X-ray incidence side of the X-ray detecting elements. The mask is formed with a pattern of shield portions in line form each extending substantially parallel to the channel direction (X direction) to shield edges of all the X-ray detecting elements arranged in the x direction from incident X-rays. Thereby, the instability of sensitivity of X-ray detection of the edges of the X-ray detecting elements and arrangement errors of the X-ray detecting elements in the slice direction (Y direction) are canceled out.Type: GrantFiled: October 19, 1999Date of Patent: October 16, 2001Assignee: Kabushiki Kaisha ToshibaInventors: Akira Adachi, Kenji Igarashi
