Driving device for a lens assembly |
| abstract |
The present invention provides a simple and compact lens driving device with a shake suppression function. In a VCM lens driving device 10, the driving coil 15 mounted on the outer circumference of the lens holder 11 includes a first to third coils 15a-15c wound around a Z axis, and the permanent magnet 16 mounted on the casing 13 and opposite to the driving coil 15 with spacing includes a first to fourth magnets 161-164. The first magnet 161 and the second magnet 162 are arranged at a position facing the first coil 15a at the middle of the lens holder 11; the third magnet 163 is arranged at a position facing the first coil 15a and the second coil 15b at the imaged-object side of the first coil 15a; the fourth magnet 164 is arranged at a position facing the first coil 15a and the third coil 15c at the opposite side to the imaged-object side of the first coil 15a. |
