Title:
CAMERA MODULE AND ELECTRONIC DEVICE INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2010079271
Kind Code:
A
Abstract:

To prevent generation of a smear in a camera module including a lens drive section and a moving magnet type mechanical shutter which are driven by electromagnetic force.

The camera module 1 includes the moving magnet type mechanical shutter 2 and a lens unit 3 for driving a lens by electromagnetic force. A magnetic field for driving the lens is set so that a light path is closed by a shutter fin while a magnetic field leaked from the lens unit 3 is acting on a drive mechanism of the mechanical shutter 2. With the configuration, the leak magnetic field leaked from the lens unit 3 causes the light path to be closed at a faster speed by the shutter fin of the mechanical shutter 2.
