In addition, when with 2 support 231A, when 241A sets according to freely the mode of moving on optical axis direction respectively, near the above-mentioned support portion 210A of supporting member 21A, be arranged on the connecting rod EN0 that lens 10 optical axis directions extend, and the connecting rod EN1 that extends along lens 10 optical axis directions is set in above-mentioned the 1st alar part 211A end and the 2nd alar part 212A end, EN2, by by 3 connecting rod EN0, EN1, near among the EN2 support portion connecting rod EN0,2 support 231A of together support, 241A, and with remaining connecting rod EN1, EN2 supports 2 support 231A respectively, the end of 241A is thus with each support 231A, 241A according to be installed in each support 231A, coil 234A on the 241A, 244A supports along the mode that optical axis direction moves freely together.
Therefore, 2 driving mechanism 23A, 24A are situated between respectively to be made by the 1st drive point D1 and keep module 20 rotation around connection shaft point 22A and the 2nd drive point D2 the 1st, and are situated between to be made by the 2nd drive point D2 and keep module 20 coupling shaft point 22A and the 1st drive point D1 the 2nd rotate on every side.
In addition, under the situation that as present embodiment, constitutes each driving mechanism,, need become compact shape as a whole owing to becoming the 1st drive division 23 and the 2nd drive division 24 respectively by alar part 211A, the 212A assembly of supporting member 21A and the shape that supports.
Therefore, with reference to exploded view, the structure of each member of the image blur correcting unit 2A of pie graph 6 is described in detail.
Fig. 6 is the exploded view after the image blur correcting unit of Fig. 4 decomposes.
The maintenance module 20A that possesses lens and imageing sensor is illustrated in the lower left of Fig. 6.Form spherical protuberance at an a bit i.e. axle point 22A along this maintenance module 20A periphery, from along the axle point 22A that keeps module 20A periphery at the 1st drive point D1 and the 2nd drive point D2 that mutually different the 1st direction and the 2nd direction separate respectively, spherical protuberance 201A, 202A also are set.In addition, Fig. 6 is in order to understand the shape of member of formation easily, though each protuberance 201A, 202A are being represented under the state that keeps module 20A to separate, protuberance 201A, 202A all are installed in as shown in Figure 6 respectively and keep module 20A.Represented following situation in addition: constitute the 1st drive point D1 in order to make, the part of the 2nd drive point D2, can accept to keep shaking of module 20A on one side, one side freely receives from the driving force of the 1st driving mechanism 23A and the 2nd driving mechanism 24A and shakes maintenance module 20A, insert the axle that leading section has protuberance 201A at compression spring SP1, SP2 hollow bulb, be installed among the maintenance module 20A.
Support the supporting member 21A that this keeps module 20A, not only has support portion 210A, and possess: in the middle of this support portion 210A is placed and extend in the 1st direction and the 2nd direction respectively, the 1st alar part 211A and the 2nd alar part 212A that keep the 1st driving mechanism 23A and the 2nd driving mechanism 24A respectively are provided with the concave surface that is used to receive as the protuberance of the axle point 22A of above-mentioned maintenance module 20A at this support portion 210A.This keeps the protuberance 22A of module to engage with the concave surface of supporting member 21A, and the common connecting rod EN0 that inserts in hole 231H1,241H1 that the end of 2 support 231A, 241A that above-mentioned the 1st driving mechanism 23A and the 2nd driving mechanism 24A possess separately is provided with, and when hole 231H2,241H2 in the opposition side end that is arranged in 2 support 231A, 241A inserted connecting rod EN1, EN2 respectively, maintenance module 20 relative supporting member 21A shown in Figure 4 were supported as to shake freely.Opposition side end at these 2 support 231A, 241A, except that inserting logical hole 231H2, the 241H2 by above-mentioned connecting rod EN1, EN2, be provided with the recess 2311A, the 2411A that link with the protuberance of above-mentioned maintenance module 20A drive point D1, D2,, these recesses 2311A, 2411A constitute drive point D1, D2 thereby engaging with the protuberance 201A, the 202A that keep module respectively, thus, when Jie drove maintenance module 20 respectively independently by these drive points D1, D2, can put 22A with axle was that maintenance module 20 is shaken at the center.
Promptly, recess 2311A, 2411A that coil 234A, 244A are installed in above-mentioned 2 support 231A, 241A and these 2 support 231A, 241A respectively respectively with the protuberance 201A that keeps module 20A to possess, state that 202A is connected under, by the energising of coil 234A, 244A 2 support 231A, 241A are moved along optical axis direction respectively, thus, becoming maintenance module 20A is that the center is shaken with axle point 22A.
And, in this example, interaction between magnetic field that the energising of the coil substrate 234A by being possessed by image blur correcting unit 2A forms and the magnetic field that forms by magnet 233A with support 231A under the situation that coil substrate 234A moves along optical axis direction, when not knowing the position of coil substrate 234A, even 2A is installed to Fig. 1 with this correcting unit, in the digital camera shown in 2 etc., digital photographing pusher side control part can not use image blur correcting unit 2A to carry out the control that hand shakes well, thus, be equipped with position probing Hall element 2341A at coil substrate 234A, to allow to correctly to control the posture that keeps module 20A.
But, among the image blur correcting unit 2A shown in Figure 4,, when digital camera shown in Figure 2 drops etc., need not have the engaging disengaging between drive point D1, D2 protuberance and the recess and keep module 20A to break away from from supporting member 21A at Fig. 1.Otherwise the image blur correcting unit akinesia causes carrying out the hand revisal of shaking.
In addition, needing does not have following situation yet: according to the outbound course of drawing flexible base, board 200A from the sensor base plate 201A that keeps module 20A to possess, by keeping the stress application to flexible base, board 200A that shakes of module 20A, flexible base, board breaks away from from sensor base plate 201A.Otherwise even from the control part side electric signal is provided to correcting unit, electric signal can not be delivered to image blur correcting unit, and makes image blur correcting unit sink into the akinesia state.
Therefore,, not only design the outbound course of flexible base, board 200A, and adopt the structure of adding mobile limiting member 202A, 203A according to the mode that keeps module 20A not come off from supporting member 21A to image blur correcting unit 2A shown in Figure 4.
Fig. 7 illustrates how from keeping module 20A to draw the figure of flexible base, board 200A.In addition, Fig. 8 is the stereographic map of the state when being fixed on support portion BASE in the portable set from the supporting member 21A that the front oblique upper possesses to the image blur correcting unit 2A of the formation of observed Fig. 7.
The figure of the positive observed image blur correcting unit 2A in top of Fig. 7 (a) expression, the figure of the observed from the side image blur correcting unit 2A of Fig. 7 (b) expression.In addition, Fig. 7 (c) expression keeps the state before module 20A is installed to supporting member 21A.
At first, the outbound course that how designs flexible base, board 200A is described.
The spherical protuberance that forms at the axle point 22A of the maintenance module 20A shown in Fig. 7 (c) contacts under the situation of engaging with the concave surface that the support portion of supporting member 21A forms, and just becomes the shape of Fig. 7 (a).
Shown in Fig. 7 (c), this flexible base, board 200A, an end is connected with sensor base plate 201A; From the part that this sensor base plate 201A extends at least at first,, extending with respect to the direction of the 1st direction and the inclination of the 2nd direction from keeping module 20A toward the outer side.
Therefore, the 1st drive point D1 is formed on the 2nd drive point D2: be connected the 1st drive point D1 and above-mentioned axle point the 2nd and link the 2nd drive point D2 and each position that the 1st of above-mentioned axle point 22A intersects with an angle of 90 degrees degree roughly mutually.The part from the initial extension of the sensor substrate of flexible base, board 200A from keeping module 20A toward the outer side, is being the directions extension of roughly 45 degree with respect to the 1st direction and the 2nd direction.
Like this, owing to can near shaking minimum axle point 22A, flexible base, board 200A be drawn obliquely, so, can reduce the stress that is applied on the flexible base, board 200A even keep module 20A to shake also, and the unfavorable condition that the connecting portion with sensor base plate 201A is broken away from is difficult to produce.In addition, the connecting portion with the control part of the portable set side that this image blur correcting unit has been installed also is difficult to break away from.
And, image blur correcting unit 2A shown in Fig. 7 (a), be installed in Fig. 1, when digital camera shown in Figure 2 is inner and supporting member 21A is fixed on the support portion BASE of portable set inside such as digital camera as shown in Figure 8, for when digital camera falls not this image blur correcting unit 1A break away from from supporting member 21A and support portion BASE, the mobile limiting member 202A, the 203A that possess notch 2021A, 2031A that Fig. 8 represents are fixed on supporting member 21A and BASE side, support portion by screw.
In this embodiment, notch 2021A, the 2031A of mobile as shown in Figure 8 limiting member 202A, 203A are limited in the moving range that keeps the optical axis direction of module 20A in each protuberance that the 1st drive point D1 and the 2nd drive point D2 possess separately and the retainable scope of engaging of each recess of accepting each protuberance.
For example, 20A will be when Fig. 8 lower side comes off in the maintenance module, because notch 2021A by mobile limiting member 202A, 203A, following side 20211A, the 20311A restriction of 2031A keeps moving of module 20A, so can prevent to keep module 20 to break away from from supporting member 21A and support portion BASE.On the contrary, will be when Fig. 8 upper side comes off in the maintenance module, because upper face side 20211B, the 20311B of notch 2021A, 2031A by mobile limiting member 202A, 203A restriction keeps moving of module 20A, so can prevent to keep module 20 from supporting member 21A and support portion BASE disengaging.
Just, even Fig. 1, the digital camera of the image blur correcting unit that is built-in with Fig. 8 shown in Figure 2 drops, also since the engaging of drive point D1, D2 protuberance and recess keep by notch 2021A, the 2031A of mobile limiting member 202A, 203A, prevented that maintenance module 20A breaks away from from supporting member 21A and support portion BASE, so, pick up the digital camera that drops, utilize this digital camera just can not need the shake photography of revisal of hand at once.
At last, to the yawing moment of this image blur correcting unit, the spinning movement of pitching direction describes.
Fig. 9 is the figure of explanation image blur correcting unit action.Fig. 9 (a) expression is from the stereographic map of the observed image blur correcting unit of front oblique upper.Fig. 9 (b) represents the observed figure by the maintenance module 20A of the 2nd driving mechanism 24A after yawing moment drives from the left side side of the stereographic map shown in Fig. 9 (a) in addition.Fig. 9 (c) expression is from the observed figure by the maintenance module 20A of the 1st driving mechanism 23A after the pitching direction drives in the left side of the stereographic map shown in Fig. 9 (a).Fig. 9 (d) expression is observed by the 1st driving mechanism 23A and the 2nd driving mechanism 24A from the stereographic map left side side shown in Fig. 9 (a), the figure of the maintenance module 20A after yawing moment, pitching direction all drive.
Shown in Fig. 9 (a),, will keep module 20A to support in the mode of shaking freely by the 1st driving mechanism 23A and the 2nd driving mechanism 24A that supports by supporting member 21A.
For example, do not drive when keeping module the limit B that is used to support the limit A of the supporting member 21A that keeps module 20A and the sensor base plate 201A almost parallel that becomes at the 1st driving mechanism 23A and the 2nd driving mechanism.
At this, when keeping module 20A to drive, shown in Fig. 9 (c), keep module 20A to rotate in the pitching direction like that by the 1st driving mechanism 23A.When observing the state of this moment, between the limit B of limit A that keeps module 20A and supporting member 21A, produce from Fig. 9 (a) left side side.
In addition, driving by the 2nd driving mechanism 24A under the situation that keeps module 20A, keeping module 20A to tilt along yawing moment.When observing the state of this moment, shown in Fig. 9 (b), keep the interval of the limit D (with the vertical limit of above-mentioned limit B) of the limit C (with the vertical limit of above-mentioned limit A) of module 20A and supporting member 21A to keep almost parallel ground to expand like that from Fig. 9 (a) left side.
And, driving simultaneously by two driving mechanism 23A, 24A under the situation that keeps module 20A, shown in Fig. 9 (d), keep module 20A in rotation around the 1st and also rotation around the 2nd, the 1st and the 2nd inclination that becomes shown in Fig. 9 (a) relatively like that.Among Fig. 9 (d),, utilize supporting member limit E and keep producing between the module limit F situation that situation about tilting is represented the state identical with the state that tilts in the pitching direction owing to can not represent this state well.
That is,, keep module 20A, can make to keep module 20A to be in free position by utilizing the 1st driving mechanism 23A and the 2nd driving mechanism 24A to drive respectively according to above-mentioned image blur correcting unit 2A.
Such image blur correcting unit being provided under the situation of camera for example etc., no matter there is what kind of hand to shake, drive and keep module and hand is shaken by revisal according to eliminating mode that this hand shakes, there not be the distinct image of shaking thereby can access.
Example when at last, the image blur correcting unit of present embodiment being applied to the mobile phone that has camera describes.
