Abstract

In order to provide an imaging device capable of performing a focusing operation and having a more compact structure, the driver is disposed in the space around the minimum effective aperture lens caused by the difference between the outer diameter of the minimum effective aperture lens and the maximum effective aperture lens. At least a part of the driver is used to drive the moving focusing lens group during focusing, thereby manufacturing a compact imaging device with increased driving force.

Description

technical field [0001] The present invention relates to a compact imaging device using a solid-state imaging device such as a CCD image sensor or a CMOS image sensor, and more particularly to an imaging device equipped with an autofocus mechanism and a method for assembling the imaging device. Background technique [0002] In recent years, as the performance of imaging devices using solid-state imaging elements such as CCD (Charge Coupled Device) image sensors and CMOS (Complementary Metal Oxide Semiconductor) image sensors has increased, a number equipped with an autofocus mechanism has been installed. (hereinafter referred to as AF mechanism) mobile phones with imaging devices are spreading. Furthermore, there is an increased demand for further miniaturization of these imaging devices. As an imaging device having such an AF mechanism, Patent Document 1 and Patent Document 2 disclose, for example. [0003] Patent Document 1: (Japanese) Unexamined Patent Publication No. 20...
