Publication number: 20070273364Abstract: A lens position detecting device 200 has a position detecting magnet 202, a magnetic force detecting sensor 204, a positional information generating means 206, etc. The position detecting magnet 202 is mounted on a rear surface of a lens holder frame 1460. The magnetic force detecting sensor 204 serves to generate a detected signal having a magnitude depending on the intensity of a magnetic force generated from the magnetic poles of the position detecting magnet 202. The magnetic force detecting sensor 204 is disposed on a straight line that passes through the position detecting magnet 202 parallel to the optical axis. The magnetic force detecting sensor 204 outputs a detected signal having a voltage corresponding (proportional) to the intensity of the magnetic force. An amplifying circuit 208 of a positional information generating means 206 amplifies the detected signal Ss from the magnetic force detecting sensor 204.Type: ApplicationFiled: August 18, 2005Publication date: November 29, 2007Inventors: Tomoya Takei, Toshifumi Takaoka, Hideo Takagi, Yoshikazu Ito, Masanori Hayashi, Tomohiro Yasui, Hideki Yamaoka, Kentaro Tashita

Patent number: 6917375Abstract: The present invention relates to image-formation on any selected kind of objective body. The characterizing features reside in such that, based upon fed image data, required images are formed on an image-transferable sheet acting for image carry-over service and in reliance on sublimation image transfer technique, and then, by the use of said sheet with said images thus formed thereon, the formed images thereon are transferringly applied on the objective body. By adopting the above measures, the objective body can be formed sharply and clearly with any desired images, irrespective of kind and configuration thereof, with such superior results of highly improved unity and solidability between the formed images and the objective body to be decorated with.Type: GrantFiled: April 2, 2002Date of Patent: July 12, 2005Assignee: Dai Nippon Insatsu Kabushiki KaishaInventors: Masanori Akada, Noritaka Egashira, Shunsuke Mukasa, Takao Suzuki, Hideo Hosoi, Yoshikazu Ito, Jumpei Kanto, Mitsuru Takeda, Masaki Kutsukake, Yasuo Otatsume

Patent number: 6504623Abstract: A multiple function printer for reliably re-magnetizing MICR character on a cut-sheet form without regard to operator experience or the manner in which the form is inserted method. The transportation mechanism of the printer drives the cut-sheet form inserted in an insertion opening of the printer in reverse until the leading edge of the form is detected by a top-of-form (TOF) detector disposed in the insertion opening. Next, the cut-sheet form 5 is fed in reverse to position the beginning of the MICR characters on the form within the effective flux density range of the magnetizing magnet 17. The cut-sheet form is then advanced forward from this position to re-magnetize and then read the MICR characters using a magnetic head.Type: GrantFiled: December 29, 1998Date of Patent: January 7, 2003Assignee: Seiko Epson CorporationInventor: Yoshikazu Ito

Patent number: 6490050Abstract: Paper jams and damage to a printing medium resulting from movement of a print head carriage are prevented in a printing apparatus in which the print head unit moves orthogonally to the direction in which the printing medium, which may be slip form, is transported through a transportation path to the printing unit for printing. A pair of transportation rollers are supported on opposing sides of the transportation path in a manner enabling the transportation rollers to close and open. The transportation rollers are closed to hold and transport the slip form in the transportation path to the printing unit. A driver is controlled to open and close the transportation rollers according to a control command. When a non-print control command involving print head movement is received, the driver is controlled to close the transportation rollers.Type: GrantFiled: September 4, 1998Date of Patent: December 3, 2002Assignee: Seiko Epson CorporationInventor: Yoshikazu Ito
