  • Patent number: 7417804
    Abstract: A lens barrel has a base, a second lens holder frame holding a second lens group, a first lens holder frame holding a first lens group, a cam ring, and a fixed ring. The second lens holder frame has three guides projecting axially from an outer circumferential portion of an annular plate and disposed at circumferentially equally spaced intervals. Guide grooves are defined in respective portions of the annular plate which are radially inwardly faced by the guides. Guide posts engage respectively in the guide grooves, so that the second lens holder frame is nonrotatably, but axially movably supported by the guide posts.

  • Publication number: 20070273364
    Abstract: 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.

  • Patent number: 6984135
    Abstract: A press fit pin of the present invention has a press-fitted region to be press-fitted and connected to a conductive through hole of a printed circuit board or other circuit substrate. The press-fitted region is formed into substantially an M-shape in cross-section, which has two beam-like regions extending substantially in parallel, and a connection region connecting the beam-like regions in a deformable manner. The connection region is formed into such an arcuate shape in cross-section that an upper surface corresponding to a valley side of the M-shape is a concave surface and an opposite lower surface is a convex surface. A part of the upper surface is partially located on the lower surface side with respect to a straight line L connecting left and right inner side continuous portions where the lower surface of the connection region and inner surfaces of the two beam-like regions are continuous to each other.

  • Patent number: 6917375
    Abstract: 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.

  • Patent number: 6504623
    Abstract: 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.

  • Patent number: 6490050
    Abstract: 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.
