  • Angle detector
    Patent number: 6566863
    Abstract: A position detector comprising a sensor head and rod is formed to have an arc-like configuration along a rotation locus of a rotating body and an amount of movement of the sensor head along the rod is converted to an angle by dividing the movement amount by a curvature radius common between the rod and the sensor head. By doing so, the rotation angle of the rotating body is calculated.
    Type: Grant

    Date of Patent: May 20, 2003
    Assignee: Kabushiki Kaisha Toshiba
    Inventors: Seijiro Yamamoto, Yuuji Furuta
  • Gimbal mechanism
    Patent number: 6536724
    Abstract: A gimbal is rotatably supported about a Z axis by one pair of support columns fixed to a mounting surface. A motor and angle detector are provided on the gimbal to control a rotation of an image pickup section about a Y axis. By a coil unit formed on the mounting surface, a magnet mounted on the gimbal is driven to rotate the gimbal about a Z axis. The rotation angle of the gimbal is detected by a relative positional relation between a sensor head fixed to the gimbal and rod bent in an arc-like configuration to follow a rotation focus of the gimbal.
