摘要: A lens driving apparatus includes a holder and driver for providing linear motion to the along an optical axis of lens. The electromagnetic mechanism, provided at outer circumference in enclosing manner, generating torque around axis; switching mechanism generated force so as linearly move holders. surrounds allow smaller sized than that where is side apparatus. In addition, prevents from moving axial direction, when power turned off or even external applied holder.
