<P>PROBLEM TO BE SOLVED: To provide a lens drive device, an autofocus camera, and mobile terminal with a camera, which are easy to manufacture, are lessened in blocking the drive of a lens support, and are able to move in the direction of the optical axis of a lens support and move for correcting shake of a hand holding the camera. <P>SOLUTION: According to four springs 12a to 12d supporting the lens support 5 so that the support is freely moved, coils 19 and 16a to 16 are connected to the four springs 12a to 12d such that one end of the first coil 19 is connected to the power source side spring 12b, and one end of each of the second coils 16a and 16c and one end of each of the second coils 16b and 16d are connected to the power source side springs 12a and 12c, and the other end of each of the coils 19 and 16a to 16d is connected to the spring 12d in a reference potential side. When a lens support 5 is moved in the direction of an optical axis, a DC current is caused to flow in the first coil 19. When the lens support 5 is moved in an X-Y direction orthogonal to the optical axis, predetermined DC current is caused to flow in the predetermined second coils 16a to 16d. <P>COPYRIGHT: (C)2012,JPO&INPIT |
