Embodiment Construction

[0025] use Figure 1 to Figure 18 A lens barrel of an imaging device as an embodiment of the present invention will be described.

[0026] The lens barrel 1 of the present embodiment has a photographic optical system consisting of a first group lens with positive refractive power, a second group lens with negative refractive power, a third group lens with positive refractive power, and a lens group with positive refractive power. The fourth group of lenses with positive refractive power constitutes, and the lens barrel 1 is a kind of lens barrel that can be retracted in the non-photography state, and each movable mirror frame part can be retracted. An imaging device with an image blur correction function of an imaging element moving in the imaging plane of the system is built into a digital camera.

[0027] In addition, in the following description, the optical axis of the imaging lens of the imaging optical system is denoted by "O". In the direction of the optical axis O, t...

Abstract

An image pickup apparatus of the present invention includes: a fixed frame; a zoom lens holding frame; a focus lens holding frame; a focus driving unit and a zoom driving unit; an image pickup device; a base plate that is coupled to the fixed frame and displaceably supports the image pickup device; an X driving unit that drives the image pickup device in an X direction; and a Y driving unit that drives the image pickup device in a Y direction, wherein the focus driving unit is placed in an upper left portion of the fixed frame, the zoom driving unit is placed in a right side portion, and further the Y driving unit is placed in an upper right corner of the base plate and the X driving unit is placed in a lower right corner.

Description

technical field [0001] The present invention relates to an imaging device having an image blur correction function. Background technique [0002] Conventionally, there is an imaging device disclosed in Japanese Patent Application Laid-Open No. 2008-48220 as an imaging device having an image blur correction device that supports an imaging element so that it can move in a two-dimensional direction perpendicular to the optical axis of a lens ( X, Y directions) to drive the imaging element so as to be able to correct the image blur. The fixing plate part of the imaging element. [0003] The conventional imaging device described above has a first movable frame displaceable in the Y direction and a second movable frame relatively displaceable in the X direction relative to the first movable frame, and an imaging element is mounted on the second movable frame. In addition, in the above-mentioned base, when viewed from the front along the optical axis of the lens, the first drivin...
