Position relationship to magnet 1101,1102, yoke 13 and coil 1401a, 1401b carries out more specific description.As shown in Fig. 7～Fig. 9, coil 1401a, 1401b respectively with the inside surface arranged opposite of magnet 1101,1102.As mentioned above, coil 1401a, 1401b are bundled into the tabular of extending along optical axis direction (Z-direction shown in Fig. 1), become its one side (face in outside) and magnet 1101,1102 opposed and another side (face of inner side) and the opposed state of yoke 13.Like this coil 1401a, 1401b are bundled into the tabular of extending along optical axis direction, therefore can reduce coil 1401a, 1401b with the orthogonal direction of optical axis direction on size, thereby realize the miniaturization of the size of the apparatus main body in the direction orthogonal with optical axis direction.
Yoke 13 is disposed at the inner side of above-mentioned coil 1401a, 1401b.The size of the yoke 13 on optical axis direction (Z-direction shown in Fig. 8, Fig. 9) is configured to shorter than the size on the equidirectional across the opposed magnet 1101,1102 of coil 1401a, 1401b difference.Yoke 13 is made up of the magnetic sheet metal of tool, therefore by the magnetic attraction from magnet 1101,1102.Therefore the lens holder 7 that, is fixed with yoke 13 becomes also by the state drawing towards magnet 1101,1102 side draughts.In this case, lens holder 7 is drawn by maintaining part 604 side draughts towards support unit 6.In addition,, under not to the original state of coil 1401a, 1401b energising, lens holder 7 is configured in the neutral position of the optical axis direction of support unit 6 by the magnetic force acting between magnet 1101,1102 and yoke 13.
As shown in Figure 7, in the 605a of the incorporating section of support unit 6, be accommodated with hooking sheet 703 and the ball 1501 of lens holder 7.As mentioned above, lens holder 7 because of between magnet 1101,1102 and yoke 13 effect magnetic force drawn by maintaining part 604 side draughts towards support unit 6.Therefore, ball 1501 is clamped in the internal face of hooking sheet 703 and teat 703a and with it between the internal face of opposed incorporating section 605a.Similarly, in the 605b of incorporating section, be accommodated with hooking sheet 704 and the ball 1502 of lens holder 7.Ball 1502 is clamped in the internal face of hooking sheet 704 and teat 704a and with it between the internal face of opposed incorporating section 605b.As shown in Figure 7, ball 1501,1502 is disposed in two positions circumferentially leaving of this lens holder 7 to clip the mode of central portion of lens holder 7.In addition area configurations magnet 1101 and magnet 1102 these both sides of a side who is divided in the plane each other of the center by through ball 1501 and ball 1502.Thus, ball 1501,1502 is subject to the magnetic force of magnet 1101,1102 and under stable state, remains between lens holder 7 and support unit 6.
In addition, between magnet 1101,1102 and yoke 13, the magnetic force of effect is configured to the degree that lens holder 7 can move along optical axis direction (Z-direction shown in Fig. 7).Therefore, ball 1501,1502 is clamped in lens holder 7(more specifically in the mode that can roll, is hooking sheet 703,704) internal face and with it between the internal face of opposed incorporating section 605.The ball 1501,1502 that, is accommodated in incorporating section 605a, 605b become allow lens holder 7 optical axis direction move and be maintained at the state between support unit 6 and lens holder 7.
As shown in Figure 8, Figure 9, be fixed on sheet metal 602(602a, the 602b of support unit 6) magnet 1101,1102 and be fixed on coil 1201,1202 arranged opposite of upside FPC9, downside FPC3.The magnetic detecting element 1001a that is installed on the lower surface of downside FPC3 is configured in corresponding with the central portion of magnet 1101, coil 1201 respectively position (with reference to Fig. 9).Similarly, the magnetic detecting element 1001b that is installed on the lower surface of downside FPC3 is configured in corresponding with the central portion of magnet 1102, coil 1202 respectively position (with reference to Fig. 8).
In addition, in magnet 1101,1102, there is different magnetic poles along the radial arrangement of lens holder 7.In addition,, in magnet 1101, the magnetic pole that is disposed at a side's of upper side magnet 1101a is configured to different magnetic poles from the opposing party's who is disposed at lower side the magnetic pole of magnet 1101b.For example, the Outboard Sections of magnet 1101a is geomagnetic into the S utmost point, and inner side part is geomagnetic into the N utmost point.The Outboard Sections of magnet 1101b is geomagnetic into the N utmost point, and inner side part is geomagnetic into the S utmost point.Similarly, in magnet 1102, the magnetic pole that is disposed at a side's of upper side magnet 1102a is configured to different magnetic poles from the opposing party's who is disposed at lower side the magnetic pole of magnet 1102b.For example, the Outboard Sections of magnet 1102a is geomagnetic into the S utmost point, and inner side part is geomagnetic into the N utmost point.The Outboard Sections of magnet 1102b is geomagnetic into the N utmost point, and inner side part is geomagnetic into the S utmost point.
Secondly, the action of the related lens driver 1 of present embodiment is described.First, to utilizing the inner magnetic field producing of magnet 1101,1102 frameworks at lens driver 1 to describe.In the framework inside of lens driver 1, as shown in Figure 8, Figure 9, produce magnetic field at the periphery of magnet 1101,1102.
In the magnetic field producing at the upper side of magnet 1101,1102, produce the magnetic line of force of advancing toward the outer side from the inner side of magnet 1101,1102.On the other hand, in the magnetic field producing in the lower side of magnet 1101,1102, produce the magnetic line of force of advancing towards inner side from the outside of magnet 1101,1102.Coil 1201,1202 is configured on the path of the magnetic line of force that forms above-mentioned magnetic field.In addition, magnetic detecting element 1001a, 1001b are configured on the path of the magnetic line of force in the magnetic field of the lower side generation that is formed in magnet 1101,1102.
In addition, in the magnetic field producing in the inner side of magnet 1101,1102 (lens holder 7 sides), produce from the magnet 1101a, the 1102a that are disposed at upper side towards being disposed at the magnet 1101b of lower side, the magnetic line of force that 1102b advances.On the other hand, in the magnetic field producing in the outside of magnet 1101,1102, produce from the magnet 1101b, the 1102b that are disposed at lower side towards being disposed at the magnet 1101a of upper side, the magnetic line of force that 1102a advances.
Coil 1401a, 1401b are configured on the path of the magnetic line of force in the magnetic field of the inner side generation that is formed in magnet 1101,1102.In particular, the path that is formed in the magnetic line of force in the magnetic field of the inner side generation of magnet 1101,1102 is controlled by the yoke 13 of the periphery that is fixed on lens holder 7.Increasing by being disposed in the magnetic loop that magnet 1101a, the 1102a of upper side, the magnet 1101b, the 1102b that are disposed at lower side and yoke 13 form, being configured to the magnetic line of force of reporting to the leadship after accomplishing a task with coil 1401a, 1401b.
Producing like this under the situation in magnetic field, in the time of current flowing in coil 1401a, 1401b, on above-mentioned coil 1401a, 1401b, producing thrust (Lorentz force).By the thrust producing like this, lens holder 7 is mobile along optical axis direction (Z-direction shown in Fig. 7～Fig. 9).
For example, when flow through from paper shown in Fig. 8, Fig. 9 the inboard electric current towards side direction nearby (Fig. 8 for X-axis positive dirction, Fig. 9 in be Y-axis negative direction) in the upper side part of coil 1401a, 1401b, on coil 1401a, 1401b, produce the thrust of Z axis positive dirction (upper direction).On the contrary, when flow through in the upper side part of coil 1401a, 1401b from paper nearby side inwardly side direction (Fig. 8 for X-axis negative direction, in Fig. 9, be Y-axis positive dirction) electric current time, on coil 1401a, 1401b, produce the thrust of Z axis negative direction (lower direction).In this case, because magnet 1101,1102 is fixed on support unit 6, so with above-mentioned thrust accordingly lens holder 7 move along optical axis direction.
In lens driver 1, for example, by according to indicating to the magnitude of current towards coil 1401a, 1401b energising and towards controlling thrust from the driving of carrying the portable phone of lens driver 1 or the control part of digital camera, make coil 1401a, 1401b move up and down to carry out its location.Thus, the location of the lens holder 7 of coil 1401a, 1401b can be fixed, and the location of the phacoid of lens holder 7 can be assembled in.In addition, when the energising of the coil 1401a of present dynasty, 1401b stops, lens holder 7 turns back to neutral position (initial position) by the magnetic force acting between magnet 1101,1102 and yoke 13.
In the time that lens holder 7 moves along optical axis direction like this, follow and support unit 6 between under the state that contacts of the ball 1501,1502 that arranges lens holder 7 move.Thus, the friction can reduce lens holder 7 and move along optical axis direction time, therefore can make lens holder 7 move swimmingly.In particular, ball 1501,1502 is disposed in two positions leaving across the central portion of lens holder 7 in the time overlooking, therefore can support lens holder 7 at two positions significantly leaving with respect to support unit 6, thereby can make lens holder 7 stably move along optical axis direction.In addition, support unit 6 has rectangular-shaped in the time overlooking, above-mentioned ball 1501,1502 is disposed in the position corresponding with the diagonal angle of support unit 6, therefore can effectively utilize and easily become the corner part of the support unit in dead band 6 periphery, thereby can make the compact in size of the apparatus main body in the direction orthogonal with optical axis direction.
In addition, in lens driver 1, form and make coil 1401a, 1401b and the yoke 13 of the travel mechanism that lens holder 7 moves along optical axis direction be installed on lens holder 7, the magnet 1101,1102 that forms this travel mechanism is installed on support unit 6.Therefore, compared with the situation that is installed on lens holder 7 with above-mentioned magnet 1101,1102, can make lens holder 7 lightweights, can make lens holder 7 move swimmingly.
In particular, in lens driver 1, yoke 13 is made up of the single part with electric conductivity, and this yoke 13 is installed on lens holder 7, and in yoke 13, is connected with one end of coil 1401a, 1401b.Thus, as utilizing yoke 13 to the power supply path of coil 1401a, 1401b, therefore can carry out electric power supply to coil 1401a, 1401b with simple structure.
In addition, as mentioned above, the other end of coil 1401a, 1401b is connected with the metal parts 5 that is fixed on support unit 6.The electric current of above-mentioned coil 1401a, 1401b is supplied with in messenger wire 4, the metal parts 5 of downside FPC3 via solder.Like this, in lens driver 1, using above-mentioned messenger wire 4 and metal parts 5 as the power supply path of coil 1401a, 1401b is used, therefore just can carry out electric power supply to coil 1401a, 1401b with simple structure without thering is special structure.
On the other hand, producing as described above under the situation in magnetic field, in the time of current flowing in coil 1201,1202, on above-mentioned coil 1201,1202, producing thrust (Lorentz force).By the thrust producing like this, support unit 6 is accompanied by the swing of messenger wire 4 and moves along X-direction and Y direction shown in Fig. 8, Fig. 9.
For example, when divide the electric current of the X-axis negative direction (from nearby side side direction inwardly of paper) flowing through shown in Fig. 8 in the inside portion of coil 1202a, 1202b, on coil 1202a, 1202b, produce the thrust of Y-axis negative direction (right shown in Fig. 8).On the contrary, when divide the electric current of the X-axis positive dirction that flows through shown in Fig. 8 (inboard towards side direction nearby from paper) in the inside portion of coil 1202a, 1202b, on coil 1202a, 1202b, produce the thrust of Y-axis positive dirction (left shown in Fig. 8 to).Also be identical for coil 1201a, 1201b shown in Fig. 9.In this case, coil 1201,1202 is fixed on downside FPC3, upside FPC9, therefore with above-mentioned thrust accordingly support unit 6 along moving with the orthogonal direction of optical axis direction.
In lens driver 1, for example, by according to indicating to the magnitude of current towards coil 1201,1202 energisings and towards controlling thrust from the driving of carrying the portable phone of lens driver 1 or the control part of digital camera, make the orthogonal direction of magnet 1101,1102 edges and optical axis direction move to carry out its location.Thus, the location of the fixing support unit 6 of magnet 1101,1102 can be supplied, and the location of the lens holder 7 of this support unit 6 can be supported on.In addition, when the energising of present dynasty's coil 1201,1202 stops, support unit 6 is by the elastic force of messenger wire 4 and turn back to initial position.
As described above, present embodiment related in lens driver 1, dual-purpose is supplied with the magnet 1101,1102 that makes magnetic force that lens holder 7 moves and supply make the magnetic force that support unit 6 moves, and above-mentioned magnet 1101,1102 is disposed at the periphery of a side of the direction orthogonal with the optical axis direction of lens holder 7 (X-direction shown in Fig. 8, Fig. 9 and Y direction), therefore, do not need to configure as clipped lens holder 7 the situation of pair of magnet and guarantee the space in the both sides of lens holder 7 configuration pair of magnet.Thus, can make the compact in size of the apparatus main body in the direction orthogonal with optical axis direction.
In addition,, in lens driver 1, under original state, by the magnetic force of effect between magnet 1101,1102 and yoke 13, lens holder 7 is remained on to the neutral position of the optical axis direction of support unit 6.Thus, can shorten the displacement while making lens holder 7 move to a side (upper side) of optical axis direction or the extreme position of opposite side (lower side), therefore can reduce needed magnitude of current when lens holder 7 is moved.
And then, in lens driver 1, under original state, by the magnetic force of effect between magnet 1101,1102 and yoke 13, lens holder 7 is remained on to the neutral position of the optical axis direction of support unit 6, therefore, do not need, for making lens holder 7 turn back to the special construction of neutral position, therefore can suppress the parts number of constituent apparatus main body.And, because the size of the yoke 13 on optical axis direction is configured to shorter than the size of magnet 1101,1102, so the scope configuration yoke 13 can the relatively strong magnetic force among the magnetic field producing from magnet 1101,1102 feeding through to, therefore can be configured in lens holder 7 with high precision the neutral position of the optical axis direction of holder.
And then, in lens driver 1, in support unit 6, be embedded with sheet metal 602, clip sheet metal 602 for 2 groups of magnet 1101,1102 that the orthogonal direction of support unit 6 edges and optical axis direction is moved and arrange and arrange at optical axis direction.Thus, can guarantee magnetic force that support unit 6 is moved, can make support unit 6 along and the orthogonal direction of optical axis direction move swimmingly.And, form support unit 6 owing to burying sheet metal 602 underground, thus can make support unit 6 there is the intensity for keeping 2 groups of magnet 1101,1102, and can guarantee the degree of freedom of the design of support unit 6.Thus, for example, even if in the case of one end of messenger wire 4 is connected with support unit 6, also can avoids the size of support unit 6 to become large, and can form this coupling part.

In addition in the above-described embodiment, the situation that ball 1501,1502 is disposed in to the position corresponding with the diagonal angle of support unit 6 to clip the mode of central portion of lens holder 7 is illustrated.But, being not limited to above-mentioned position for the configuration of ball 1501,1502, can suitably change.For example, also above-mentioned ball 1501,1502 can be disposed in to two positions circumferentially leaving of the lens holder different from the diagonal angle of support unit 67.Even if in this case, two positions also lens holder 7 circumferentially can being left at it are supported on support unit 6, therefore can guarantee stability and can make lens holder 7 move along optical axis direction.But, preferably the position that arranges ball 1501,1502 is made as to two positions of the central portion that clips lens holder 7.
And then, in the above-described embodiment, to utilizing single part to form yoke 13, and this yoke 13 is illustrated as the situation that the power supply path of coil 1401a, 1401b is used.But, be not limited thereto for structure and the function of yoke 13, can suitably change.For example, also can utilize multiple parts to form yoke 13.In addition also can form not as the structure that the power supply path of coil 1401a, 1401b is used.
