  • Pressing mechanism for an image shake suppressing optical device
    Patent number: 8081222
    Abstract: A pressing mechanism is adapted for use in an image shake suppressing optical device that includes a driving unit and an image capturing unit. The pressing mechanism is adapted to be disposed between the driving unit and the image capturing unit, and includes an arm body and a press head unit. The arm body has a driven end that is adapted to be connected to the driving unit, and a connecting end that is opposite to the driven end. The press head unit is adapted to be disposed between the connecting end of the arm body and the image capturing unit, and is adapted for providing a resilient pressing force on the image capturing unit when the driven end of the arm body is driven by the driving unit to move the connecting end in a pressing direction.
