  • Patent number: 8369024
    Abstract: A lens driving device includes a movable system having a lens frame to which a lens is fixed, and a fixation system including a guide shaft inserted into a guide hole formed in the lens frame to allow the lens frame to advance and retract in an optical axis direction and a restricting member for restricting rotation of the lens frame about the guide shaft. A lead screw is rotatable with respect to the fixation system about its axis which extends substantially parallel to the guide shaft, and the lead screw is threadedly fitted to the movable system. A motor rotates the lead screw to allow the movable system to advance and retract along the lead screw. A biasing spring is arranged substantially parallel to the guide shaft and biases the lens frame in both the axial direction and a direction orthogonal to the axial direction.

  • Patent number: 8279534
    Abstract: A lens driving device has a motor mounted to a plate, a lead screw connected to the motor for undergoing rotation about an axial line thereof, a nut threadingly engaged with the lead screw, and a casing mounted to the plate for housing the lead screw and the nut. The nut has a convex protruding portion protruding outwardly from an outer peripheral surface of the nut. The casing has a fitting groove linearly formed in the casing in a direction of the axial line for receiving the protruding portion in a state in which the protruding portion is fitted in the fitting groove so as to regulate rotation of the nut, and for movably guiding the protruding portion in the fitted state in the direction of the axial line to move the nut back and forth along the lead screw.

  • Publication number: 20120174574
    Abstract: A drive module includes: a lower plate spring 7 which is connected to an end surface of a lens frame 4 and an end surface of a module frame 5 arranged in a ?Z direction; and a module lower plate 8 which is arranged on a ?Z side of the lower plate spring 7 and restricts the movement of the lens frame 4 and the lower plate spring 7 in the Z direction. An intermediate member 80 is arranged between the lower plate spring 7 and the module lower plate 8. To set hardness of the intermediate member 80 closer to hardness of the lower plate spring 7 than hardness of the module lower plate 8 is, the module lower plate 8 is made of a resin material and the lower plate spring 7 and the intermediate member 80 are made of a metallic material.

  • Publication number: 20120120513
    Abstract: A drive module includes a drive unit having a cylindrical supporting member, a driven member accommodated inside the supporting member, and a driving unit configured to reciprocally move the driven member along the axial direction of the supporting member. A top-covered cylindrical cover is attached to the drive unit and covers the drive unit. The cover includes a metallic exterior packaging member configured to cover at least an outer periphery of the drive unit to shield the drive unit from external electromagnetic fields, and a resin spacer attached to the exterior packaging member, the spacer having engaging portions engageable with the drive unit to achieve positioning of the cover.

  • Publication number: 20090249901
    Abstract: Provided is a lens driving device (1) including: a lead screw (4) connected to a motor fixed to a plate (2); a nut (5) which is threadingly engaged with the lead screw (4), and has a convex protruding portion (5a); a casing (6) fixed to the plate; a fitting groove (11) for fitting the protruding portion in the fitting groove (11) so as to regulate rotation of the nut, and movably guiding the protruding portion in a fitted state in a direction of an axial line (L1) to move the nut back and forth; and a lens frame (8) including a lens holding portion (8a) for holding a lens and an abutting portion (8b) abutting the nut, and formed so as to move in accordance with back-and-forth movement of the nut to move the lens back and forth in the direction of the axial line. At least one of the casing and the protruding portion has a tapered surface (13) formed so as to forcibly guide the protruding portion toward the fitting groove to gradually change to the fitted state.

  • Patent number: 5268769
    Abstract: An image signal decoding system for decoding a variable length image data compressed by a modified Huffman code. The decoding object data is cut by a fixed length of 13 bits and the cut data is decoded by using a decode-encode circuit for decoding the input of the modified Huffman code with its end portion equalized and for encoding and generating the code length, the code kind and the run-length number on the basis of the decoded contents, and by using a rotator for shifting the bit data. For decoding a code which immediately follows, the data is shifted with the rotator by the bit number of the code length of the decoding output result, the end portion of the next decoding output result, the end portion of the next decoding object data is equalized with the input end portion of the encode-decode circuit, and it is placed after the immediately following decoding object data and is then input into the decode-encode circuit and decoded.
