Abstract

The present invention relates to a lens driving device that can prevent adhesive from intruding into a front spring during the manufacturing process of the lens driving device, an autofocus camera and a mobile terminal with a camera, wherein the lens driving device has a lens support; a coil; An annular ring mouth on the peripheral side that allows the lens support body to move freely; a magnet fixed on the ring mouth and arranged opposite to the coil; a front side spring and a rear side spring that keep the lens support body freely moving; The base is placed on the rear side of the ring mouth in the direction of the optical axis and holds the rear spring; the frame is arranged on the front side of the ring mouth in the direction of the optical axis and holds the front spring. The lens support moves back and forth along the optical axis direction of the lens based on the electromagnetic force generated when the coil is energized. The front spring is provided with a gap from the ring mouth and is held on the frame.

Description

technical field [0001] The present invention relates to a related lens driving device, an auto-focus camera, and a mobile terminal with a camera. The so-called mobile terminal refers to a mobile phone, a portable information terminal (PDA), a notebook computer, and the like. Background technique [0002] In Patent Document 1 (JP Unexamined Publication No. 2010-211242), a lens driving device is disclosed, which has: a ring mouth; a base for loading the ring mouth; a frame for configuring the ring mouth between the bases; A cylindrical lens support body on the side; a front side spring disposed on the front side of the lens support body in the optical axis direction. The outer peripheral portion of the front spring is clamped between the collar and the frame. According to the technology of this patent document 1, the front side spring can be sandwiched between the collar and the frame. [0003] In the manufacturing process of the lens driving device, after mounting the ring...
