Problems solved by technology

[0004] To put it simply, in the lens driving device for small cameras, the movement to the optical axis direction (Z direction) of the lens support body and the movement to the X-Y direction (handshake correction) only need to move the lens support body. Such a function has not yet been provided.
[0005] In addition, the movement in the direction of the optical axis of the lens support can be achieved by using the technology of Patent Document 1, but in the technology of Patent Document 1, it is only possible to move in the X direction, and the optical axis intersects to the handshake correction (X-Y direction) Surface movement cannot be done

Abstract

The invention provides a lens driving device, an automatic focusing camera and a mobile terminal device in a simple configuration, wherein a lens support body can be moved toward an optical shaft direction and the hand shake correction movement can also be realized. In a lens driving device 1, a second annular coil 16a-16d is closer to the optical axis direction of the lens compared with a first annular coil 19. Meanwhile, the second annular coil 16a-16d is turned and rotated along the inner and outer peripheral sides of the radial direction of a lens support body 5. The inner periphery and the outer periphery of a lodestone 17 have different magnetic poles. The inner peripheral part of the lodestone 17 faces the outer peripheral surface of the first annular coil 19. The lodestone 17 is also facing the outer peripheral side part of the second annular coil 16a-16d in the optical axis direction. When the lens support body 5 moves toward the optical axis, the first annular coil 19 is energized. When the support body 5 moves toward the X-Y direction orthogonal to the optical axis, the second annular coil 16a-16d is energized.

Description

technical field [0001] The present invention relates to a lens driving device, an automatic focus camera and a mobile terminal device with a camera function. Background technique [0002] Patent Document 1 (Patent Publication No. JP2002-373435) discloses a driving device for light harvesting in which a first loop coil and a second loop coil are arranged at intervals of 90 degrees on the peripheral surface of a lens support body. Toroidal coils, and a magnet opposite to each toroidal coil is arranged on the outer side of the lens support in the radial direction, and the lens support is moved to the optical axis direction (focus direction) and the radial direction (X direction) after the toroidal coil is energized. move. [0003] On the other hand, in a small camera, only the lens support is moved in the direction of the optical axis. If it is moved in the X-Y direction to prevent vibration, then it is necessary to drive the entire lens driving device in the X-direction and t...
