The second incised notch mouth 71xb and the 3rd incised notch mouth 71xc are respectively to form with the both ends ways of connecting of the first incised notch mouth 71xa.The second incised notch mouth 71xb and the 3rd incised notch mouth 71xc are provided with in the mode across Hall element 61x, and go up at the length direction (Y direction) of X side FPC70x and to extend configuration.Thus, the 71x of incised notch portion integrally is formed and roughly is the U font.
Fig. 6 is the cut-open view of the VI-VI line of fluctuation correction device among Fig. 2.As shown in Figure 6, Y side FPC70y also similarly has the first return portion 70ya, the second return portion 70yb, installation portion 70yc and the 71y of incised notch portion with X side FPC70x.As shown in Figure 2, the 71y of incised notch portion, same with the 71x of incised notch portion, integrally formed and roughly be the U font.Y side FPC70y, FPC70x has same formation with the X side, so detailed.
Above Shuo Ming camera apparatus 1, by the shutter release 4 of operation setting in camera body 3, convertibility camera lens 2 is had rocks detecting sensor 5 and detects around the angular velocity of X-axis and Y-axis and exported.To be called jolt (Pitch) around rocking of X-axis, will be called around rocking of Y-axis and wave (Yaw), and rock corrective action and for example be, by the image that produces that rocks that results from this two direction is rocked to proofread and correct and finishes.
Like this, fluctuation correction device 10, because the recuperability of FPC70 acts on the direction that relatively moves with respect to fluctuation correction device shell 30 with movable camera lens frame 40 mutually on the direction of quadrature, therefore can not become the obstruction of VCM50 when for casing cover 33, driving movable camera lens frame 40 in perpendicular to the plane of optical axis.Like this, also just improved the correction accuracy of fluctuation correction device 10.
(2) for example, when driving movable camera lens frame 40 by VCM50x on X-direction, power then acts on and the length direction of Y side FPC70y mutually on the direction of quadrature.Though Y side FPC70y is directed to the recuperability of the FPC of this twisting because of this acting force twists, the recuperability in the time of for example will restoring to the original state with the FPC that has been bent is compared, and is in fact little of negligible degree.Therefore, can not become for fluctuation correction device shell 30 obstruction when driving movable camera lens frame 40.
(3) recuperability of X side FPC70x and Y side FPC70y because with identical to the direction that movable camera lens frame 40 applies power by spring 42 (42a, 42b), does not apply power so can not hinder 42 pairs of movable camera lens frames 40 of spring.Like this, make on the direction of movable camera lens frame 40 near end face 30b because the recuperability of X side FPC70x and Y side FPC70y acts on, so fluctuation correction device 10 can use the little spring of elastic force to constitute spring 42.In addition, according to circumstances also can omit spring 42.
(4) Fig. 7 is the cut-open view of the fluctuation correction device of Comparative Examples, is the cut-open view of the part suitable with Fig. 5 of the fluctuation correction device of expression embodiment.
The fluctuation correction device 110 of Comparative Examples is with the difference of the fluctuation correction device 10 (with reference to figure 5) of embodiment: have the FPC170 that is not formed with the 71x of incised notch portion at installation portion 170xc.

At this, FPC70x, 170x want restorable recuperability, act on the direction that the installation portion 70xc, the 170xc that make FPC70x and FPC170x get off from the surface isolation of movable camera lens frame 40.Make this installation portion 70xc, 170xc from the power that movable camera lens frame 40 separates, approach the second return portion 70xb, 170xb more and become big more.
The fluctuation correction device 110 of Comparative Examples shown in Figure 7, for example, when the power that FPC170x is separated when FPC170x being attached at the cohesive force of the cementing agent on the movable camera lens frame 40, FPC170x separates from movable camera lens frame 40.
If FPC170x separates from movable camera lens frame 40, then Hall element 61x changes with respect to the position of movable camera lens frame 40, thereby might correctly calculate the amount of movement of movable camera lens frame 40 for fluctuation correction device shell 30.
To this, the fluctuation correction device 10 of embodiment shown in Figure 5 because the first incised notch mouth 71xa is formed between the Hall element 61x and the second return portion 70xb, is cut off in this part from the power on the direction of movable camera lens frame 40 separation so act on FPC70x.Therefore, in the near zone of the Hall element 61x in FPC70x, the zone of approaching the second return portion 70xb can prevent to separate from movable camera lens frame 40.
And, shown in Fig. 2 (b),, therefore, similarly, FPC70x is cut off because of these incised notch mouths from the power that movable camera lens frame 40 separates owing to be formed with the second incised notch mouth 71xb and the 3rd incised notch mouth 71xc across Hall element 61x.Like this, near the zone the Hall element 61x in FPC70x,, can prevent to separate from movable camera lens frame 40 than the zone of the second incised notch mouth 71xb and the 3rd incised notch mouth 71xc inside (Hall element side).
In addition, in Fig. 5, in FPC70x, across Hall element 61x and the zone of a side opposite with the first incised notch mouth 71xa, because leave from second return portion 70xb punishment, the power that FPC70x is separated from movable camera lens frame 40 has arrived negligible in fact degree for a short time.
In view of the above, Hall element 61x is more stable with respect to the position of movable camera lens frame 40, thereby can calculate the amount of movement of movable camera lens frame 40 for fluctuation correction device shell 30 reliably.Above effect also is same about Hall element 61y shown in Figure 6.
