Embodiment Construction

[0021]Below, an embodiment of the invention will be explained referring to the drawings and the like.

[0022]FIG. 1 is a drawing conceptually showing the camera 1 which is one embodiment of the present invention.

[0023]Further, in each of the drawings below, in order to facilitate explanations and understanding, an XYZ Cartesian coordinate system has been established. In this coordinate system, in the camera position in the case of photographing a landscape format image with the photographer holding the optical axis OA horizontal (below referred to as the correct position), the direction going towards the left side as seen from the photographer is the X plus direction and the direction going upwards in the correct position is the Y plus direction. Furthermore, the direction towards the photographic subject in the correct position is the Z plus direction. This Z plus direction is called the front face side, and the Z minus direction is called the rear face side. Furthermore, a movement ...

Abstract

A lens barrel having an image forming optical system including a first optical system and a second optical system which is moveable independently from the first optical system, a first driving portion which drives the first optical system during a magnification changing operation of the image forming optical system, and a second driving portion which drives the second optical system during the magnification changing operation, along with driving the second optical system during a focus adjustment of the image forming system.

Description

[0001]This is a Continuation of application Ser. No. 13 / 009,431 filed Jan. 19, 2011, which is a non-provisional application, and claims priority under 35 U.S.C. §119 to Japanese Patent Application No. 2010-010881 filed on Jan. 21, 2010. The content of the application is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a lens barrel and to an imaging device.[0004]2. Description of the Related art[0005]Japanese Unexamined Patent Publication No. 2000-89086 discloses an internal focusing zoom lens barrel which changes the focal point of the optical system by moving a middle lens of the optical system, changing the magnification of the optical system by changing spacing of a plurality of lenses.SUMMARY OF THE INVENTION[0006]The lens barrel of the above mentioned prior art has a complex structure combining a large number of parts. Because of this, there are many production requirements, and it...
