Problems solved by technology

In this case, not only the vibration-type driving device whose driving direction intersects the moving direction at a right angle or an angle close to a right angle does not contribute to the driving, but also due to the contact between the movable body and the vibration-type driving device And the generated frictional force also loads the movement of the movable body, causing energy loss, which results in loss of output
This leads to a decrease in characteristics when used, for example, as a two-dimensional drive device, image blur correction device, interchangeable lens, image pickup device, or automated stage

[0103] The third embodiment differs from the first embodiment in the configuration of the movement mechanism 25 . This will be described. Figure 13A is a perspective view of the kinematic mechanism 25 and the driven body 18 . Figure 13B is its front view. The X direction in the figure is the driving direction (first direction) of the vibration type driving device 24 . The Y direction is a yaw direction (second direction) along which the movable body 19 and the driven body 18 can move relative to each other by means of the movement mechanism 25 .

[0104]The guide members 20 are connected to the movable body 19 and have a trapezoidal shape in cross-section in the X and Y directions and each have a groove in the Y direction (the deflection direction or the second direction). The follower transmission portions 23 of the follower 18 have a trapezoidal shape in cross-section in the X and Y directions and each have a groove extending in the Y direction (the deflection direction...

Abstract

A vibration type driving apparatus including: a vibrator including an electro-mechanical energy conversion device; a driven body between the vibrator and a movable body and driven in a first direction by the vibrator; and a moving mechanism that allows the movable body to move in a second direction relative to the driven body, in which the second direction is a direction intersecting the first direction in a plane parallel to a plane where the vibrator and the driven body are in contact with each other.

Description

technical field [0001] The present invention relates to a vibration-type driving device and a two-dimensional driving device including the vibration-type driving device, an image blur correction device, an interchangeable lens and an image pickup device, and an automated stage. Background technique [0002] Various vibration-type drive devices have been proposed that excite vibrations in a vibrator so as to move a movable body that is in press contact with the vibrator. Oscillating drive devices are positioned as important functional components especially in optical devices that require precise manipulation. An example thereof is a two-dimensional driving device in which a plurality of rectilinear motion type (type capable of linearly moving a movable body) vibration type driving devices are arranged, and their driving operations are combined so as to allow movable Two-dimensional motion of the body. Another example is an image blur correction device using such a two-dimen...
