<P>PROBLEM TO BE SOLVED: To solve the problem that although a lens actuator which uses an expansion member advantageous in thickness reduction as a driving source is used with respect to an imaging function mounted on a mobile phone etc., at present, the lens actuator varies in output with temperature change because of its structure. <P>SOLUTION: Flat temperature characteristics are actualized by constituting a lens actuator structure having an annularly arranged lever part coupled, and then providing an inverter material to a back plate and blocks for temperature compensation at both ends of the driving source respectively. <P>COPYRIGHT: (C)2013,JPO&INPIT |
