Document Type and Number:
Japanese Patent JP2004038058
Kind Code:
A
Abstract:
To provide a lens moving mechanism being advantageous for miniaturization and a camera and an electronic apparatus which incorporates the lens moving mechanism.
When a first mobile lens support frame 2016 is moved in the direction of an optical axis by contraction of a first shape memory alloy 2028 or a second shape memory alloy 2030, a cam plate 2046 is shaken around a support shaft 2048 in accordance with movement of a first cam pin 2042. A second cam groove 2052 is moved by shake of the cam plate 2046 and thereby a second cam pin 2044 is moved, and thus a second mobile lens support frame 2020 is moved in the direction of the optical axis.
