Lens driving apparatus
View Patent ↗A lens driving apparatus with a lens portion having at least one lens, a base portion on which an image sensor detecting light coming through said lens portion can be fixed, a driving portion capable of relatively moving said lens portion in a vertical direction to a light axis of said lens portion and in a parallel direction to the light axis of said lens portion with respect to said base portion, and at least three suspension wires connecting a focus portion including said lens portion and said base portion so as to allow a relative movement. The suspension wires are arranged outside a magnet of said driving portion along the vertical direction to the light axis.
1. A lens driving apparatus comprising:
a lens portion having at least one lens,
a rectangular movable portion including the lens portion,
a fixing portion including a circuit board capable of supplying electricity to the movable portion,
a first driving portion configured to move the movable portion relatively to the fixing portion along a vertical direction to a light axis,
a second driving portion configured to move the lens portion relatively to the fixing portion along the light axis, and
a supporting portion connecting the movable portion and the fixing portion so as to allow a relative movement of the movable portion and the fixing portion to the vertical direction to the light axis, wherein
a magnet attached to the movable portion is arranged at a corner of the movable portion, and
the circuit board in the fixing portion is electrically connected to a coil of the second driving portion through the supporting portion.
2. The lens driving apparatus as set forth in claim 1 , wherein
the supporting portion is provided at four corners of the lens driving apparatus.
3. The lens driving apparatus as set forth in claim 1 , wherein
the fixing portion has an image sensor configured to detect a light coming through said lens portion.
4. The lens driving apparatus as set forth in claim 1 , wherein
a resilient portion connecting to the supporting portion is divided in at least two.
5. The lens driving apparatus as set forth in claim 1 , wherein
the supporting portion is constituted by at least three or more suspension wires.
6. The lens driving apparatus as set forth in claim 1 , wherein
the magnet is on a hypothetical line connecting between the supporting portion and the light axis.
7. The lens driving apparatus as set forth in claim 1 , wherein
a shortest distance between the supporting portion and the light axis is longer than a shortest distance between the magnet and the light axis.
