Problems solved by technology

[0004] However, in the device described in Patent Document 1, the position detection sensor is arranged on the outer side of the position where the actuator is arranged, so the shake correction device is enlarged.
In addition, since the position detection sensor is separated from the imaging element, the error amount tends to overlap and the position detection accuracy of the imaging element decreases.

Abstract

The present invention provides a shake correcting device, which can ensure the device miniaturization and accurately detect the relative position of a camera shooting element. An X-axis actuator (320x) and a Y-axis actuator (320y) are arranged near respective positions of fictitious intersection points (P) at length directional axis (Lx, Ly) but not intersection, a position detecting component for detecting the relative position of CCD(31) is arranged in areas (E) containing fictitious intersection points (P) and surrounded by each one end of the X-axis actuator (320x) and the Y-axis actuator (320y), thus the device can be ensure miniaturization by a dead space generated by the arrangements of the X-axis actuator (320x) and the Y-axis actuator (320y). Furthermore, the present invention can reduce error quantity by arranging the position detecting component near the position of CCD(31), and accurately detect the relative position of CCD(31).

Description

technical field [0001] The present invention relates to a shake correction device for correcting hand shake in an imaging device such as a digital camera. Background technique [0002] Conventionally, in an imaging device, there is a shake correction device that uses an actuator (actuator) to make an imaging element such as a CCD independent in the horizontal direction and the vertical direction in a plane perpendicular to the imaging optical axis in order to correct the hand shake. The position of the subject light beam formed on the imaging plane of the imaging element is corrected by shifting the ground (for example, refer to Patent Document 1). In this case, in order to control the driving amount of the actuator, it is necessary to have a position detection sensor that detects the relative position of the imaging element that is displaced and moved. Here, in Patent Document 1, the position detection sensor is disposed outside the actuator that operates the imaging devic...
