  • Voice coil focusing system having an image receptor mounted on a pivotally-rotatable frame
    Patent number: 5245172
    Abstract: An apparatus for focusing an image onto an image receptor is disclosed. The apparatus includes a stationary lens, a rotatable frame that is rigidly connected to the image receptor, and a base. The base is pivotally connected to the rotatable frame about a rotational axis. The image is focused by the stationary lens onto the image receptor by pivoting the rotatable frame about the rotational axis. In an alternate embodiment, an apparatus for focusing an image onto an image receptor includes a stationary lens, a voice coil actuator, a servo loop for driving the voice coil actuator, and an electromechanical transducer for measuring the position of the image receptor. The electromechanical transducer is electrically connected to the servo loop. Connecting means for rigidly connecting the image receptor to the voice coil actuator are also provided. The image is focused by the stationary lens onto the image receptor by driving the voice coil actuator.
