Embodiment 1

[0028] Figure 1 to Figure 3 A shaking device 10 according to a first embodiment of the present invention is shown. The swing device 10 has a first member 12 and a second member 14 overlapping in the Z direction in a three-dimensional XYZ rectangular coordinate system.

[0029] The first member 12 and the second member 14 are formed in a square plate shape as viewed from the Z direction. The first member 12 is, for example, a movable body, and the second member 14 is a fixed body. Furthermore, the first member 12 swings around the X and Y directions and the Z axis with respect to the second member 14 as will be described later.

[0030] The first part 12 has an opposite surface 16 opposite to the second part 14, and on the opposite surface 16, for example, two X-direction guide grooves 18, 18, X-direction guide grooves 18, 18 parallel to the X-axis and extending toward the X-axis are formed. The cross-section is V-shaped, formed near the ±Y direction end of the first member...

Embodiment 2

[0051] Figure 6 as well as Figure 7 A shaking device 10 according to a second embodiment of the present invention is shown.

[0052] The structure of the first embodiment guides the ball 24 through the X-direction guide groove 18 and the Y-direction guide groove 22 , as opposed to it, while the structure of the second embodiment guides the ball 24 through the rollers.

[0053] that is, Figure 7 As shown, the balls 24 are arranged on the ball arrangement grooves 46 formed at the four corners of the first part 12 and the second part 14, and the balls 24 arranged in the ball arrangement grooves 46 are supported by rollers 48 in the X direction and in the Y direction. Support rollers 50 are supported.

[0054] The ball arrangement groove 46 extends in the X direction and the Y direction, and moves the ball 24 in the X direction and the Y direction.

[0055] For the group of X-direction support rollers 48, it has two (i.e. a pair) X-direction support shafts 52 extending in t...

Abstract

The invention relates to a shaking device, an optical component driving device, and an electronic apparatus. For the most basic unit shaking device, in a three-dimensional XYZ rectangular coordinate system, a first part and a second part which are overlapped in the Z direction are arranged, and a plurality of X-direction guide grooves parallel to the X-axis direction are formed in the opposite face, opposite to the second part, of the first part; and a plurality of Y-direction guide grooves parallel to the Y-axis direction are formed in the face, opposite to the first part, of the second part.And ball bodies are embedded in the X-direction guide grooves and the Y-direction guide grooves. The configuration makes it possible to reduce the thickness of the shaking device, the optical memberdriving device, and the electronic device in the Z direction.

Description

technical field [0001] The invention relates to a shaking device, an optical component driving device and electronic equipment. Background technique [0002] It is well known, for example, that as a lens driving device for driving a lens, it drives the lens in both XY directions in a three-dimensional XYZ Cartesian coordinate system with the Z direction as the optical axis direction to perform shake compensation. For example, Patent Document 1: the publication date is December 7, 2006, the Japanese patent document whose document number is JP2006330678A, and patent document 2: the publication date is November 29, 2006, and the document number is the Chinese patent document CN1869763A. The corresponding structure of the above-mentioned lens driving device for driving the lens is described. [0003] In the above-mentioned Patent Document 1, as a three-stage structure of a fixed body, an intermediate support body, and a movable body, they are stacked in the Z direction, and bet...
