Problems solved by technology

That is, for example, as Figure 7 As shown, when the magnet base 33 is reciprocated in the X direction by flowing the current +ia and the current -ib to the X-side rocking coil 35x and then flowing the current +ia again, even if the current value of the same magnitude is flowing In the case of +ia, the amount of shaking in the X direction also produces a difference in ΔXa, resulting in hysteresis
Therefore, the center position of the subject imaged on the image sensor (not shown) changes with shaking, and there is a possibility that an image that the photographer did not intend to be captured may be captured.

Embodiment approach 1

[0065] figure 1 is a perspective view showing the hand-shake correction device 10 according to Embodiment 1, figure 2 is an exploded perspective view of the hand shake correction device 10, image 3 It is a perspective view of main parts showing a part of the brake member 16 of the hand-shake correction device 10 cut away. Hereinafter, let the optical axis direction of the lens not shown be the Z (Z-axis) direction, let the subject side be the front of the Z direction (+Z side), and let the two directions at right angles to the Z-axis be X (X-axis) direction and Y (Y-axis) direction.

[0066] As shown in each figure, the hand-shake correction device 10 includes a base substrate 11, a suspension wire 12, a magnet base 13, a permanent magnet 14, an X-side oscillating coil 15x, a Y-side oscillating coil 15y, and a brake member 16. Then, the permanent magnet 14 and the lens are oscillated in a direction perpendicular to the optical axis. The hand-shake correction device 10 s...

Abstract

The present invention provides a shake correction device which can not generate the hysteresis phenomenon and can suppress unnecessary resonance and improve endurance with respect to drop impact. In this shake correction device, the eddy current induction plate 16a of +Z side is opposite to and has a gap with the surface (14a) of the +Z side of the permanent magnet (14) which is arranged to wind around the optical axis at an interval of 90 degree in the Z direction, the eddy current induction plate 16b of radial direction is opposite to and has a space with the surface (14b) of the outside in the radial direction, and the eddy current induction plate 16c of the periphery direction is opposite to and has a gap with the surface (14c) in the periphery direction.

Description

technical field [0001] The present invention relates to a hand-shake correction device for correcting hand-shake generated by a mobile phone camera or the like. Background technique [0002] If the lens held by the automatic focus (automatic focus) lens (lens) driving device produces hand-shake, then the hand-shake correction device of the camera makes the lens or the automatic focus lens driving device in a direction at right angles to the optical axis direction of the lens. Shake in a certain direction, thereby suppressing the shaking or flow of the image formed on the image sensor (image sensor). For example, the hand-shake correction device described in Patent Document 1 is configured as follows: a suspension wire (suspension wire) extending along the direction of the optical axis; The way of swinging in the direction is supported by a suspension wire; and the electromagnetic drive unit has a coil for swinging and a permanent magnet. This camera-shake correction device...
