CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of application of U.S. patent application Ser. No. 12/837,512, filed on Jul. 16, 2010. The entire disclosure of U.S. patent application Ser. No. 12/837,512 is hereby incorporated herein by reference.

BACKGROUND

1. Technical Field

The technology disclosed herein relates to an imaging device and a lens barrel used with the imaging device.

2. Background Information

Imaging devices that make use of a CCD (charge coupled device), a CMOS (complementary metal-oxide semiconductor) sensor, or another such imaging sensor have become extremely popular in recent years. Examples of such imaging devices include digital still cameras and digital video cameras. These imaging devices are generally equipped with a lens barrel for forming an optical image of a subject on an imaging element. A telescoping lens barrel, with which the lens barrel is stowed in the camera body when not being used for imaging, has been used as this type of lens barrel.

SUMMARY

One aspect of the technology disclosed herein is a lens barrel that includes a flexible wire, a first supporting frame and a second supporting frame. The flexible wire has a first end with at least one terminal, a second end with at least one terminal and a bent portion disposed between the first and second ends. The bent portion includes a plurality of parts overlapping each other. The first supporting frame supports the first end. The second supporting frame is movably disposed in a first direction with respect to the first supporting frame and supports the bent portion.
