Next as Fig. 9 B, 11,18 with the same as shown in 19, flexible board 200 is rolled over (mountain fold) along at right angles be folded into the peak basically at the straight line e shown in Figure 17, thereby extend along Y-Z plane (referring to Figure 18) at 10b place, the bight of stationary cylinder 10 second extension 209.And, flexible board 200 is along the at right angles folding basically peak folding that is of straight line f, thereby extend in X-Y plane the 3rd extension 210, move along z axis towards the lens barrel side from bottom member 10 the 3rd extension 210 there, and extend to than second extension, 209 more close stationary cylinder 10 sides.Next, flexible board 200 at right angles is folded into the paddy folding basically along straight line g, thereby extend along X-Z plane (referring to Figure 18) near the 10b of the bight of stationary cylinder 10 the 4th extension 211.In addition, flexible board 200 at right angles is folded into the paddy folding basically along straight line h, thereby extend in X-Y plane the 5th extension 212, the 5th extension 212, and extends to than the 4th extension 211 more close stationary cylinder 10 sides 11 towards the lens barrel side shifting along z axis from bottom member there.Flexible board 200 at right angles is folded into paddy folding basically along straight line i, thereby the 6th extension 213 extends near the bight 10b of stationary cylinder 10 and substantially parallel with bight 10b.Modular circuit coupling part 204 so connects, thereby modular circuit coupling part 204 is from passing through folding the 6th extension 213 bendings that form along straight line i, thereby along the circumferential surface of stationary cylinder 10, and the substantially parallel plane (referring to Figure 18) of formation and X-Z plane.The end of modular circuit coupling part 204 is along near leave z axis the plane substantially the same with the plane of bottom member 11 direction bending, thereby form the plane identical, and be electrically connected with the printing board PCB (described below) which is provided with F/EIC102, operational amplifier 1253, coil actuator 1254 etc. with the plane of bottom member 11.
(installation of flexible board)
Here, will be to describing as the setting of the flexible board of major part of the present invention and the structure of installation.
The skeleton view of Figure 18 for seeing from the rear side of stationary cylinder 10 demonstrates a part of stationary cylinder part that CCD solid-state image sensing device 101, cylinder unit 7 etc. are installed on it, the printing board PCB of F/EIC102, processor 104 etc. is installed on it and is connected flexible board 200 between a part of CCD solid-state image sensing device 101 and the printing board PCB.The axis that passes the source point of image pickup device and extend along optical axis direction is a z axis, and X-Y plane is the plane along the direction vertical with z axis.Figure 19 is an enlarged drawing, demonstrate the coupling part of flexible board in detail, Figure 20 is along the cut-open view of cutting open on the Y-Z plane shown in Figure 18, Figure 21 is a side view, be used to illustrate the connection between that part of stationary cylinder 10, printing board PCB and flexible board, and Figure 22 and 23 demonstrates major part in detail, is used to illustrate the structure of the rotation and the installation of flexible board 200.
In Figure 11, the CCD platform so constitutes, thereby directions X step 13 is fixed on the bottom member 11 that is assemblied on the stationary cylinder 10, Y direction step 14 is according to can being supported along the mode that directions X slides with respect to directions X step 13, and installation step 15 be supported according to the mode that can slide along the Y direction on Y direction step 14.Solid-state image sensing device 101 is assemblied on the installation step 15 of CCD step 1251.The CCD coupling part 201 of flexible board 200 Figure 18,20 with the upper surface side shown in 21 near on installation step 15, be connected with CCD solid-state image sensing device 101 and circumferential section thereof.Processor 104 is installed on the upper surface side in Figure 18,20,21 etc. of printing board PCB.The modular circuit coupling part 204 of flexible board 200 is connected with the connector CON that is located on the lower face side in these accompanying drawings of printing board PCB.
When mounted, at first, for example the CCD coupling part 201 of flexible board 200 is connected and be fixed on CCD solid-state image sensing device 101 and the circumferential section thereof by welding.As anticipation, make flexible board 200 folding after, the modular circuit coupling part 204 of flexible board 200 is connected with the connector CON of printing board PCB, thus as in Figure 18 and the same formation as shown in 20.Then, the same as shown in Figure 21, after printing board PCB being installed on the PT1 of first, PT1 of first and stationary cylinder 10 is fixing by second portion PT2.
At this moment, owing to printing board PCB is fixed, so be difficult to printing board PCB is installed on the PT1 of first by accurately fixing position relation.
Because stationary cylinder 10 and printing board PCB are fixed by second portion PT2 and the PT1 of first mutually, change so assemble its position relation at every turn.Like this, when the position relationship change occurring between stationary cylinder 10 and printing board PCB, the position relation between the CCD of flexible board 200 connector 201 and treatment circuit connector 204 also changes.In order to absorb X and the kinetic reacting force of Y direction by CCD solid-state image sensing device 101, suppress as image blurring, the extension connector 205 of flexible board 200 suitably crooked with form with the parallel plane first of X-Z and with the parallel plane second portion of Y-Z.
But, as mentioned above, when the position between the CCD of flexible board 200 connector 201 and treatment circuit connector 204 relation changes, reverse and stretch to be created in knifeedge and extend in the connector 205 and uncertain.Therefore, can not ignore kinetic reacting force by CCD solid-state image sensing device 101.In order to address this problem, one of them solution is to make treatment circuit connector 204 and stationary cylinder 10 to be fixed into one.But when above-mentioned change in location occurred, treatment circuit connector 204 produced strain with respect to the fixed position, and this further produces slight deformation and strain in extending connector 205.
On the other hand, above the bending of embodiment of the present invention is had been described in detail.As shown in Figure 19, extend connector 205 and comprise first extension 208 of extending abreast with X-Y plane, see and first extension, 208 adjacency and second extension 209 from CCD solid-state image sensing device 101 along the z axis direction parallel towards the object guiding extension with optical axis, with second extension 209 in abutting connection with and be parallel to the 3rd extension 210 that X-Y plane extends, see the 4th extension of extending along the z axis direction towards object orientation with the 3rd extension 210 adjacency and from CCD solid-state image sensing device 101, with the 4th extension 211 in abutting connection with and be parallel to the 5th extension 212 that X-Y plane extends and with the 5th extension 212 in abutting connection with and on seeing away from the direction of object from CCD solid-state image sensing device 101 along the 6th extension 213 that the z axis direction is extended, thereby the treatment circuit connector 204 that will be connected with connector CON is provided with continuously by its end.
The plane parallel with Y-Z is arranged in second extension 209, and the plane parallel with X-Z is arranged in the 4th extension 211.Flexible board 200 is divided into the first second extension connector 207 that extends connector 206 and locate in the bottom of first extension 208.The first extension connector 206 and second extends connector 207 and unifies at 213 places, the 6th extension.When folding, it is almost completely overlapping that the first extension connector 206 and second extends connector 207.Therefore, between first extension 208 and the 6th extension, it is upwards overlapping with the second extension connector 207 as shown in the figure that the first extension connector 206 and second extends connector 207, extends connector 205 thereby form as mentioned above.
Figure 22 demonstrate according to the embodiment of the present invention the bight 10b of stationary cylinder 10 when stationary cylinder 10 (being also referred to as " stationary cylinder ") is removed flexible board 200 and near.The one side of its two sides by the bonding adhesive boards 300 of double sticky tape is attached on the outside surface of part 10b of stationary cylinder 10.The part of the 6th extension 213 of flexible board 200 is attached on the another side of adhesive boards 300.Like this, by adhesive boards 300 the 6th extension 213 is fixed on the bight 10b of stationary cylinder 10.
Figure 23 demonstrates the bight 10b that is pasted with the stationary cylinder 10 of flexible board 200 on it by adhesive boards 300.The part at the back side of the 6th extension 213 is connected on the stationary cylinder 10 by adhesive boards 300.This make win to the 5th extension 208-212 except the 6th extension 213 freely the motion and can not be subjected to reacting force.When directions X moved, the 6th extension 213 can absorb and reduce during movement the reacting force along directions X, because second extension 209 mainly changes at CCD solid-state image sensing device 101.Equally, at CCD solid-state image sensing device 101 when the Y direction is moved, because the 4th extension 211 mainly changes, so the 4th extension 211 can absorb and reduces reacting force along the Y direction.
In this case, will with the 6th extension 213 in abutting connection with and printing board PCB will be installed in treatment circuit connector 204 on the stationary cylinder 10 and will be connected on the CON time, because the 6th extension 213 fixes this fact in advance, be used to absorb the second and the 4th extension 209 of reacting force and 211 extension 206-213 can not occur because position and the change of shape that causes is installed so comprise.Therefore, can effectively prevent the degradation that causes based on fitting operation.
As mentioned above, the relative position that connects the stationary cylinder 10 of CCD connector 201 thereon of relative position of the PCB that connects with treatment circuit connector 204 can change bigger and unstable.On the other hand, according to flexible board according to the present invention 200 than at the 6th extension 213 more close PCB on the stationary cylinder 10 of being fixed on shown in Figure 19 and 23.The part of extending between the 6th extension 213 and the treatment circuit connector 204 and treatment circuit connector 204 be right after with bending before PCB is connected, thereby form ribbon respectively.Therefore, X-Y direction and Z direction that these parts trend towards respectively shown in the figure change, with the displacement of easy these directions of absorption.Specifically, near the end that be connected and can effectively absorb relatively large displacement with PCB.
Therefore, flexible board 200 according to the present invention can be connected on the unsettled PCB in its position smoothly owing to its flexibility.Flexible board 200 any variation can not occur aspect the relative position than the part that is adhesively fixed on the 6th extension 213 more close CCD connectors 201 on the stationary cylinder 10 by adhesive boards 300 except image blurring suppresses motion.PCB changes by adhesive boards 300 absorptions with respect to the relative position of the position of stationary cylinder 10.Therefore, suppressed any influence of reacting force.
The sweep that extends 208 to the 6th extensions 213, first extension of connector 205 forms along z axis at 10b place, the bight of stationary cylinder 10.Therefore, the environment space that is used for lens barrel generally forms circle, and promptly the bight 10b of stationary cylinder 10 can effectively obtain using.In addition, owing to be provided with crooked extension, so digital camera need not large scale.
The anti-bending accessory plate that is provided with flexible board 200 has prevented to produce bending by 208 to second extensions, first extension from the CCD connector 201 of flexible board 200, and the power that will be produced by the motion of installation step is applied on second extension 209 and the 4th extension 211.Therefore, can absorb reacting force reliably in these bend offices.
(second embodiment)
As mentioned above, because extend from CCD coupling part 201 in identical plane first extension 208, comprise the part corresponding so CCD coupling part 210 can extend to, thereby omitted first extension 208 basically with first extension 208.Therefore, second extension 209 can constitute by rectangular bending directly extends towards object from CCD coupling part 201, and is shown as flexible board 200 ' according to this structure of second embodiment of the invention in Figure 24.
More particularly, directly extend with parallel plane second extension 209 ' of Y-Z from CCD coupling part 201 ' along the z axis direction, and extend along the z axis direction via the 3rd extension 210 ' with parallel plane the 4th extension 211 ' of X-Z, thereby reacting force is mainly absorbed by second extension 209 ' and the 4th extension 211 '.
In addition, can extend from CCD coupling part 201 ' along the z axis direction with parallel plane first extension 208 ' of Y-Z, and extend along the z axis direction via second extension 209 ' parallel with parallel plane the 3rd extension 210 ' of X-Z, thereby reacting force can mainly be absorbed by first extension 208 ' and the 3rd extension 210 ' with X-Y plane.
(the retentive control circuit that suppresses mechanism)
Stepper motor STM1 is by controlling at the retentive control circuit shown in Figure 25.Stepper motor STM1 comprises the two-phase control structure, and comprises the first coil STMC ' with the terminal that is connected with motor driver MD3 by output line 40a, 40a '.The second coil STMC " have a terminal that is connected with motor driver MD3 by output line 40b, 40b '.Output line 40a is provided with the resistance R 18 that is used to limit electric current, and output line 40b is provided with the resistance R 19 that is used to limit electric current.Capacitor C7 is arranged between output line 40a and the output line 40a ', and capacitor C8 also is arranged between output line 40b and the output line 40b '.

Figure 26 is the process flow diagram that is used to illustrate the operation of retentive control circuit, demonstrates three steps for example reset process, dispose procedure and maintenance process.When opening the power switch SW13 of digital camera, carry out reset process (S.11) according to the control of processor 104.In this reset process, stepper motor STM1 jogging speed (pulse/sec) with 200pps under the control of processor 104 drives along counterclockwise rotating according to 2 pulses.Next, stepper motor STM1 drives along counterclockwise rotating according to 33 pulses with the fast speed of 1000pps.At last, stepper motor STM1 drives according to 2 pulses rotation along clockwise direction with the jogging speed of 200pps.
No matter where cam pin 32 is in along the sense of rotation of cam path 31, cam pin 32 is all by making stepper motor STM1 along counterclockwise rotating according to 35 pulses and contacting with the abrupt slope 31d of cam path 31.
If according to 2 pulsed drive, then cam pin 32 is arranged among the inclination starting position 31e of cam path 31 (with reference to Figure 13 E) stepper motor STM1 from contact position along clockwise direction.
In this suppresses mechanism, suppress switch SW 14 and carry out image blurring and suppress by opening, and with suppress switch SW 14 and disconnect or finish shooting and discharge image blurring simultaneously and suppress.
Connect if suppress switch SW 14, then carry out dispose procedure (S.12) by the control of processor 104.In this dispose procedure, at first stepper motor STM1 drives according to 2 pulse rotations along clockwise direction with the jogging speed of 200pps.Next, stepper motor STM1 drives according to 28 pulses rotation along clockwise direction with the fast speed of 1000pps.At last, keep 5msec to stepper motor STM1 distribution.Next, stop distribution by motor driver MD1 to stepper motor STM1.
By this dispose procedure, cam pin 32 is arranged in the inclined end portion position 31f (with reference to Figure 13 D) of cam path 31.Be approximately 43msec from inclination starting position 31e to the required time of inclination end position 31f.More particularly, cam pin 32 is approximately 43msec from keeping holding fix to move to discharging the required time of holding fix.In this release holding fix, suppress operation.
Next, if inhibition switch SW 14 disconnects or takes, then processor 104 carries out maintenance process (S.13).In this maintenance process, stepper motor STM1 jogging speed with 200pps under the control of processor 104 drives according to 2 pulses rotation along clockwise direction, and the fast speed with 1000pps drives according to 3 pulses rotation along clockwise direction then.Cam pin 32 is come the smooth paddy 31a of portion downwards by the flat top 31b that passes cam path 31 thus, thereby contacts with the smooth paddy 31a of portion.Afterwards, keep giving stepper motor STM1 distribution 5msec.
Next, motor driver MD1 stops the distribution to stepper motor STM1.Therefore, cam pin 32 is arranged among the inclination starting position 31e of cam path 31, and keeps the middle position of CCD solid-state image sensing device 101.In power supply,, then carry out these releases and keep the wait process if carry out reset process.And cam pin 32 moves to from the release holding fix and keeps the required time of holding fix to be approximately 18msec.
Comprise and be used for the installation step 15 of CCD solid-state image sensing device 101 being forced to remain on structure in the middle position owing to suppress mechanism, so needn't control distribution installation step 15 is remained in the position of source point by being formed on the pad 33 of forcing fixed head 26; Therefore when suppressing mechanism, operation can cut down the consumption of energy.

Wherein,
ω deflection (t) ... along the instantaneous angular velocity of YAW direction
ω pitching (t) ... along the instantaneous angular velocity of PITCH direction
θ deflection (t) ... the angle along the YAW direction changes
θ pitching (t) ... the angle along the PITCH direction changes
D deflection (t) ... with rotate the amount of exercise of corresponding image along directions X along the YAW direction
D pitching (t) ... with rotate the amount of exercise of corresponding image along the Y direction along the PITCH direction
θ deflection (t) and θ pitching (t) obtain by following relational expression
θ deflection (t)=∑ ω deflection (i) T
θ pitching (t)=∑ ω pitching (i) T
And, from zoom point zp and focus fp, determine focal distance f.At D deflection (t), promptly with along the corresponding picture motion amount of the rotation of YAW direction, D pitching (t), promptly with along the PITCH direction rotate corresponding picture motion amount, θ deflection (t), promptly the angle along the YAW direction changes and θ pitching (t), promptly between the angle variation of PITCH, set up following equation
D deflection (t)=f*tan (θ deflection (t)) ... (i)

That is to say, at D deflection (t), promptly with along the YAW direction rotate corresponding picture motion amount and D pitching (t) along directions X, promptly with rotate corresponding picture motion amount along the Y direction along the PITCH direction, corresponding to the amount of exercise of the CCD solid-state image sensing device 101 that should move along the X-Y direction.
If owing to camera shake occurs along the YAW direction and along the rotation displacement of PITCH direction, then the reference position (as the target location) that by top (i), (ii) calculates CCD is with drive installation step 15 like this, thus by position detecting element 1252 detected CCD solid-state image sensing devices 101 along the difference vanishing between the target location of the physical location of X-Y direction and CCD solid-state image sensing device 101.This control is carried out every T second.
In addition, if the detection of rotation sensor S1B, S2A is output as zero, then so controls installation step 15, thereby 101 translations of CCD solid-state image sensing device are moved by the translation motion displacement Xd that follows camera main-body.
(inhibition control circuit)
Figure 28 is a block scheme, demonstrates an embodiment of the control circuit that is used to suppress image blurring.Suppress circuit and comprise that feedback circuit 50 and position corresponding voltage are provided with circuit 51.Hall unit H1, H2 constitute the part that the position corresponding voltage is provided with circuit 51.Voltage Vh1 is imposed on Hall unit (1252a) H1.Hall unit H1 has the terminal that is connected with inverting terminal (-) of operational amplifier OP1 by resistance R 1 and another terminal that is connected with non-inverting input terminal (+) of operational amplifier OP1 by resistance R 3.
Operational amplifier OP1 has the lead-out terminal that is connected with the input port L1 of processor 104 and also is connected with inverting terminal (-) of operational amplifier OP1 by resistance R 1 by resistance R 5.In addition, the tie point between resistance R 5 and input port L1 is by capacitor C1 ground connection.
Voltage Vh2 is applied on Hall unit (1252b) H2.This Hall unit H2 one terminal is connected with inverting terminal (-) of operational amplifier OP2 by resistance R 7 and its another terminal is connected with non-inverting input terminal (+) of operational amplifier OP2 by resistance R 8.
Operational amplifier OP2 has by resistance R 9 and is connected with the input port L2 of processor 104 and a lead-out terminal that terminal is connected by resistance R 6 and operational amplifier OP2.In addition, the tie point between resistance R 9 and input port L2 is by capacitor C2 ground connection.
Be connected with two output lines 61,62 with D/A change-over circuit IC2, article one, output line 61 is input to non-inverting input terminal (+) of operational amplifier OP1 by resistance R 4, and another output line 62 is input to non-inverting input terminal (+) of operational amplifier OP2 by resistance R 10.
Input to from the chip selection signal D1 of output port L3, from the clock signal SCLK of output port L4 and correcting digital data DIN and to have the D/A change-over circuit IC2 that the correcting digital transformation of data is become the function of simulated data from output port L6.
D/A change-over circuit IC1 constitutes a part of feedback circuit 50.Bridging line 63 is connected with D/A change-over circuit IC1 with two output lines 64,65.Bridging line 63 is connected with coil driver MD2 with coil driver MD1.Output line 64 is connected with the input terminal L7 of coil driver MD1 by resistance R 14.Output line 65 is connected with the input terminal L8 of coil driver MD2 by resistance R 15.
Tie point between resistance R 14 and input terminal L7 is connected with the ground terminal ER1 of coil driver MD1 by capacitor C3.Tie point between resistance R 15 and input terminal L8 is connected with the ground terminal ER2 of coil driver MD2 by capacitor C4.Bridging line 63 is connected with power Vcc by resistance R 12, R11, and tie point is by resistance R 13 ground connection.
From processor 104 control signal CONT1 is inputed to coil driver MD1, MD2.Coil driver MD1 has by resistance R 16 and coil COL1 " (concatermer of coil member COL1 and coil member COL1 ') lead-out terminal of being connected.Capacitor C5 and resistance R 16 and coil COL1 " series circuit in parallel.Coil driver MD2 has by resistance R 17 and coil COL2 " (concatermer of coil member COL2 and coil member COL2 ') lead-out terminal of being connected.Capacitor C6 and resistance R 17 and coil COL2 " series circuit in parallel.
Use coil COL1 " installation step 15 is moved along directions X, and use coil COL2 " installation step 15 is moved along the Y direction.
Here, voltage Vh1-, Vh2-are applied to respectively on Hall unit H1, the H2, and be output as zero and when also having CCD solid-state image sensing device 101 to be arranged in the middle position (source point) of movable area, the detection output-voltage levels of Hall unit H1, H2 is configured to Vh1, Vh2 in the detection of rotation sensor S1B, S2A.In this case, the analog electrical output voltage level of input port L1, the L2 of processor 104 is configured to V1ADin, V2ADin respectively.Actual measurement goes out these output-voltage levels V1ADin, V2ADin.
According to rigging error coefficient and coil COL1 about the mechanical location between magnet (permanent magnet) 16a-16d and Hall unit H1, H2 relation ", COL2 " change output-voltage levels (actual measurement numerical value) V1ADin, V2ADin with respect to the rigging error coefficient between the installation site of installation step 15 etc.In addition, output-voltage levels changes according to the characteristic of Hall unit H1, H2.
Therefore, if do not proofread and correct, the detection numerical value of then corresponding with origin position Hall unit H1, H2 changes corresponding to camera; Therefore, can not carry out accurate image blurring suppresses.
Therefore, input to so setting of correction voltage Vr1 ', Vr2 ' of operational amplifier OP1, OP2 respectively from analog/digital converter IC2, thereby output-voltage levels V1ADin, V2ADin before proofreading and correct become constant voltage level (setting reference voltage level).More particularly, CCD solid-state image sensing device 101 be in the origin position and CCD solid-state image sensing device 101 when not being controlled (give coil member COL1 ", COL2 " during power supply), set correction voltage Vr1 ', Vr2 ' according to proofreading and correct in a kind of like this mode of variation of output-voltage levels (detection numerical value) V1ADin, V2ADin.
In this case, in order to set 1.7 volts of places that reference voltage level is arranged on the central numerical value of the movable range voltage that for example is essentially operational amplifier OP1, OP2, processor 104 carries out following calculating.
Here, for convenience, resistance is set at R2=R3=R7=R8, R1=R4=R10=R6, but be not limited thereto.
At R2=R3=R7=R8, under the situation of R1=R4=R10=R6, realized following relational expression.
V1ADin＝R1/R2*((Vh1+)-(Vh1-))+Vr1’
V2ADin＝R1/R2*((Vh2+)-(Vh2-))+Vr2’
This is provided with before being initially set in loading, and is the final inspection that is used to assemble camera in factory, as the same as shown in the process flow diagram of Figure 29 (reference S.21-S.23).
As shown in the process flow diagram of Figure 30, in the working control that image blurring suppresses, processor 104 loads by detection output OUT1, OUT2 according to the camera shake testing circuit and calculates the control referential data (S.31) that obtains, and loads the physical location corresponding voltage level V1ADin, the V2ADin that are obtained by Hall unit H1, H2 then; Thus, processor 104 calculates the difference (S.33) between control referential data and position corresponding voltage numerical value V1ADin, V2ADin.
Set driving voltage Vout1, Vout2 according to following equation.
Vout1＝(Vdac1-Vr)*K
Vout2＝(Vdac2-Vr)*K
Here, Vr is a dividing potential drop.
In this case, referential data K is the proportionality constant based on dividing potential drop Vr.
By magnet 16a-16d and coil COL1 ", COL2 " magnetic field attract and repel CCD solid-state image sensing device 101, thereby make it along moving by the direction of driving voltage Vout1, the Vout2 control of positive voltage or negative voltage.Changed the detection numerical value of Hall unit H1, H2 thus.Position corresponding voltage level V1ADin, V2ADin change corresponding to the variation in detecting numerical value, and position corresponding voltage level is fed back to processor 104, therefore when the detection output numerical value by the camera shake testing circuit changed the control referential data, CCD solid-state image sensing device 101 can be followed target location (S.35) smoothly.If finished shooting, then finish this control (S.36).
(alternate embodiment)
Figure 31 is a circuit diagram, demonstrates the alternate embodiment of feedback circuit 50.In this case, the driving that processor 104 comes control coil driver MD4 by PWM (pulse-length modulation control) is so that coil COL1 is given in control ", COL2 " distribution.More particularly, normal direction signal CON1 and inverse direction signal CON2 are inputed to coil actuator MD4, and input pulse voltage Vin1 and Vin2.Give coil COL1 ", COL2 " distribution voltage elongated and increase along with the duration of high level pulse signal.
(by suppressing the details that mechanism takes)
As shown in Figure 32, suppress switch SW 14 (S.41) if open, rotation sensor S1B, S2A connect (S.42).Push (S.43) to finish partly if push release-push SW1, then begin to carry out automatic focus operation (focusing operation) (S.44).Simultaneously, the mechanical forced of installation step 15 is fixedly unclamped, and by giving coil COL1 ", COL2 " distribution begins the retentive control of CCD central authorities.
Next, begin to carry out the observation process (S.45) of camera shake.Processor 104 determines whether partly pushing of release-push SW1 continues (S.46).If release-push SW1 partly pushes continuation, then processor 104 determines whether to carry out the pushing entirely of release-push SW1 (S.47).If unclamp partly pushing of release-push SW1, then S.43 this flow process gets back to step, and if do not carry out pushing entirely of release-push SW1, then S.46 this flow process gets back to step.
If release-push SW1 pushes end entirely, then begin follow (S.48) of CCD solid-state image sensing device 101 along the direction of motion of image.Next, carry out exposure (S.49).If finished exposure (S.50), then stop to follow of CCD solid-state image sensing device 101, by to coil COL1 ", COL2 " carry out distribution and control and make installation step 15 turn back to origin position (S.51), determine whether installation step 15 turns back to origin position (S.52), and CCD is forced to be fixed on (S.53) on the origin position according to mechanical mode.
There are two kinds of patterns in the operation timing of release-push SW1.
Figure 33 is the sequential chart that is used for suppressing the process of image blurring under the situation of pushing entirely of release-push SW1.In this case, push entirely and mean that unclamp operation has the uncontinuity from half pressing operation of release-push SW1 to the full pressing operation of release-push SW1, for example switches to the shooting operation that exposure begins to operate in the correct moment after half pressing operation.
If partly push release-push SW1, then begin the focusing operation of digital camera.In this state, the pressure that initial point forces maintaining body 1263 also not discharge installation step 15 keeps.Give COL1 ", COL2 " power supply, promptly these coils do not have conducting.In addition, installation step 15 is mechanically anchored in middle position, and the object image is shown on the LCD monitor 10.
If finished focusing operation, then processor 104 begins to force the stepper motor STM1 power supply of maintaining body 1263 to initial point.The mechanical forced that has discharged installation step 15 thus keeps.Simultaneously, begin to coil COL1 ", COL2 " power supply, promptly electric current is by these coils, and by to giving coil COL1 ", COL2 " inhibition controlled during half pressing operation (discharging 1) that carries out at release-push SW1 of power supply operates.If release-push SW1 is pushed entirely (discharge 2), then by to giving COL1 ", COL2 " powering to control makes installation step 15 turn back to middle position again, does not demonstrate the object image thereby cut off LCD monitor 110 then after some times.
Next, if installation step 15 is followed image according to camera shake motion is then controlled in the exposure of beginning still image.If finish still image exposure, then according to giving coil COL1 ", COL2 " power supply controls and makes installation step 15 turn back to middle position.Next, processor 104 begins to force the stepper motor STM1 of maintaining body 1263 to carry out distribution to initial point.The mechanical forced of carrying out installation step 15 is fixed thus, stops then to coil COL1 ", COL2 " power supply.
As mentioned above, even under the situation of camera shake, the user can identify LCD monitor 110 to discharge detected object image under the situation that is not having camera shake during 1.
In addition, if installation step 15 turns back to middle position during discharging 2, then move with respect to the object composition that is discharging during 1 at the composition that discharges during 2.But, according to current embodiment, can turn back to again at installation step 15 and confirm the object image before and then taking in the state of middle position, therefore can and then before taking, confirm the composition (and then before exposure) of object image.
As shown in Figure 34, if release-push SW1 is partly pushed and under the situation of not pushing release-push SW1 entirely, unclamp partly pushing of release-push SW1, then begin focusing operation simultaneously with partly pushing.If finished focusing, then processor 104 begins to force the stepped voltage STM1 distribution of maintaining body 1263 to initial point; Thus, discharged the mechanical forced maintenance of installation step 15.Simultaneously, begin to COL1 ", COL2 " power supply, i.e. these coil conductings, and give coil COL1 by control ", COL2 " the power supply inhibition carrying out (discharging 1) during half pressing operation of release-push SW1 operates.
If during half pressing operation of release-push SW1, unclamped half pressing operation of release-push SW1, then according to giving to COL1 ", COL2 " control of carrying out of powering makes installation step 15 turn back to middle position.Next, processor 104 begins to force the stepper motor STM1 power supply of maintaining body 1263 to initial point; Thus, carry out the mechanical fixation and the maintenance of installation step 15.Next, stop to coil COL1 ", COL2 " power supply.
Figure 35 is a sequential chart, demonstrates the process of inhibition when pushing release-push SW1 entirely when once taking.In this case, pushing entirely when once taking means the successional releasing operation of half pressing operation that has from release-push SW1 (discharging 1) to the full pressing operation (discharging 2) of release-push SW1, and for example horse back switches to the shooting operation that exposes and begin to operate partly pushing after.If SW1 partly pushes with release-push, then begin digital focusing operation in succession.The object image is presented on the LCD monitor 110.In addition, and then after partly the pushing of release-push SW2, carry out the full pressing operation of release-push SW1 at once.Simultaneously, cut off LCD monitor 110 so that can not demonstrate the object image.
If finished focusing operation, then processor 104 begins to force the stepper motor STM1 power supply of maintaining body 1263 to initial point; Thus, removed the machinery maintenance of installation step 15.Simultaneously, begin to coil COL1 ", COL2 " power supply, promptly described coil is switched on, and by to coil COL1 ", COL2 " powering remains on middle position with installation step 15.Therefore, carried out process of inhibition.
If by giving coil COL1 ", COL2 " power supply remains on middle position with installation step 15 and begun the still image exposure, then controls installation step 15 to follow the motion of image according to camera shake.If finished the still image exposure, then according to coil COL1 ", COL2 " power supply control make installation step 15 turn back to middle position.Next, processor 104 begins to force the stepper motor STM1 power supply of maintaining body 1263 to initial point; Carry out the mechanical fixation and the maintenance of installation step 15 thus.Next, stop to COL1 ", COL2 " distribution.
Above-mentioned pushing entirely in the situation under once taking thought and finished the composition affirmation in the operating period that discharges 1, thereby need not to confirm block diagram in the operating period that discharges 2.Therefore, even thinking discharging under the situation that turns back to middle position during 2 again at installation step 15 also needn't carry out reaffirming of composition, therefore can simplify the inhibition control procedure.
And, owing to LCD monitor 110 disconnects during focusing operation, so can avoid battery drain.In addition, since absorption bar 35 (with reference to Fig. 9 A) can be adsorbed on magnet 16b, 16d last to fix when according to mechanical system installation step 15 pressures being pressed in origin position, so can control the vibration of installation step 15 along the z axis direction.In addition, it is last with so fixing that absorption bar 35 is adsorbed on magnet 16b, 16d, thereby even also can control the vibration of installation step 15 along the z axis direction under the situation that installation step 15 is not arranged on the origin position place.
At the imaging device that has the function that is used for suppressing image blurring according to the present invention, be in the digital camera, absorption bar 35 is adsorbed on permanent magnet 16c and the permanent magnet 16d, they along the z axis direction facing to absorption bar 35, constitute on the guiding step that comprises Y direction step 14 and directions X step thereby erecting bed 15 can be adsorbed on, that is to say, installation step 15 can be adsorbed on the directions X step 13.Therefore, the position of the installation step of seeing along the z axis direction 15 can be arranged on and guide (installation step 15 is by Y direction step 14 and directions X step 13 position contacting) in the step position contacting.Can avoid being installed in the vibration of CCD solid-state image sensing device 101 (imageing sensor) on Z-direction on the installation step 15.CCD solid-state image sensing device 101 can receive light by suitable focal length.
And, because absorption bar 35 intersects along each of directions X and coil COL1, COL1 ', that is to say each that extends across coil COL1, COL1 ', thus absorption bar 35 with image blurring between inhibition period the location independent of the installation step 15 that moves on the bottom member 11 be adsorbed on permanent magnet 16c and the permanent magnet 16d.Owing to installation step 15 is moved by the magnetive attraction between among each and the permanent magnet 16a-16d among each and coil member COL2, the COL2 ' in coil member COL1, COL1 ' each, so with the location independent of each absorption bar that intersects 35 among coil member COL1, the COL1 ' and installation step be adsorbed on permanent magnet 16c and the permanent magnet 16d because permanent magnet 16c and permanent magnet 16d can apply magnetive attraction to coil member COL1, COL1 ' with the location independent ground of installation step 15.
Because permanent magnet 16c and permanent magnet 16d facing to absorption bar 35 have more microscler shape along the Y direction, so even also can apply magnetive attraction under the situation that installation step 15 moves along the Y direction.
And though in the above-described embodiment, absorption bar 35 constitutes each of crossing among coil member COL1, the COL1 ', so they can constitute each of crossing among coil member COL2, the COL2 ', and also only crosses coil member COL1.That is to say, the invention is not restricted to above-mentioned embodiment.
In the above-described embodiment, each among each among coil member COL1, the COL1 ' and coil member COL2, the COL2 ' is located on the installation step, and among the permanent magnet 16a to 16c each is located on the directions X step 13 that is included in the guiding step.But it can so constitute, thereby among the permanent magnet 16a to 16d each is located on the installation step 15, and among each and coil member COL2, the COL2 ' among coil member COL1, the COL1 ' each is located on the directions X step.That is to say, the invention is not restricted to above-mentioned embodiment.Among in coil member COL1, COL1 ' each and coil member COL2, the COL2 ' each is located under the situation on the directions X step, be located on the directions X step side promptly according to coil member COL1, COL1 ' and coil member COL2, COL2 ' in the absorption bar 35 that is provided with of at least one corresponding mode can be adsorbed among the permanent magnet 16a to 16d each.
In the above-described embodiment, absorption bar 35 is according to each setting of crossing among coil member COL1, the COL1 '.That is to say, the invention is not restricted to above-mentioned embodiment, and absorption bar 35 mainly need be adsorbed on the permanent magnet and (in this embodiment, be permanent magnet 16c and permanent magnet 16d), they are facing to absorption bar 35.Therefore, absorption bar 35 can be provided with according near the mode among each and coil member COL2, the COL2 ' that are arranged among coil member COL1, the COL1 ' each.
In the above-described embodiment, rotation sensor 1214 detect camera along the rotation of directions X and Y direction to detect the camera shake that in camera main-body (main body cover), occurs.That is to say, the invention is not restricted to above-mentioned embodiment, for example monitor that by handling image can carry out the detection of camera shake.
In the above-described embodiment, the guiding step constitutes by the Y direction step 14 that movably supports installation step 15 along the Y direction with along the directions X step 13 that directions X movably supports Y direction step.But, the invention is not restricted to above-mentioned embodiment, and can so constitute, thereby installation step 15 is movably supported along X-Y plane, and in camera main-body, fixed with respect to taking optical axis.
(the 3rd embodiment)
But, be used for treatment circuit and the image device that in imaging device, movably is controlled according to first and second embodiments for example the flexible board 200 and 200 ' that is connected of CCD solid-state image sensing device 101 have many folded parts to absorb reacting force.Therefore therefore, flexible board need be longer along its whole length, and comprise noise easily from the picture intelligence of image device.So the shape of folded part because long flexible board 200 and 200 ' and the many folded parts in flexible board 200 and 200 ' unstable, therefore easily with circumferential component appearance interference.
