More specifically, the present invention relates to a technical field in which a common guide shaft that supports a moving member and a driving member so as to be movable in a predetermined direction is provided to ensure a smooth moving operation of the moving member.

ビデオカメラやスチルカメラ等の撮像装置には、レンズ又は撮像素子を光軸方向に直交する方向へ移動させて像ぶれ補正を行う像ぶれ補正装置が設けられているものがある。   Some imaging devices such as a video camera and a still camera are provided with an image blur correction device that performs image blur correction by moving a lens or an image sensor in a direction orthogonal to the optical axis direction.

このような像ぶれ補正装置には、固定部材とレンズ又は撮像素子を保持する移動部材とを備え、移動部材が固定部材に対して光軸方向に直交する第１の方向と第２の方向の２方向へ移動可能とされたものがある（例えば、特許文献１参照）。   Such an image blur correction apparatus includes a fixed member and a moving member that holds a lens or an imaging device, and the moving member is in a first direction and a second direction perpendicular to the optical axis direction with respect to the fixed member. Some are movable in two directions (see, for example, Patent Document 1).

第１のアクチュエーターのロッドが第１の方向へ移動されることにより、このロッドの駆動力によって移動部材が第１の方向へ移動される。このとき第１のアクチュエーターのロッドは一対の第１のリニアガイドによって第１の方向へ案内され、移動部材は平行リンク機構の各アームが回動動作されて第１の方向へ移動される。   When the rod of the first actuator is moved in the first direction, the moving member is moved in the first direction by the driving force of the rod. At this time, the rod of the first actuator is guided in the first direction by the pair of first linear guides, and the moving member is moved in the first direction by rotating each arm of the parallel link mechanism.

また、第２のアクチュエーターのロッドが第２の方向へ移動されることにより、このロッドの駆動力によって移動部材が第２の方向へ移動される。このとき第２のアクチュエーターのロッドは一対の第２のリニアガイドによって第２の方向へ案内され、移動部材は平行リンク機構の各アームが回動動作されて第２の方向へ移動される。   Further, when the rod of the second actuator is moved in the second direction, the moving member is moved in the second direction by the driving force of the rod. At this time, the rod of the second actuator is guided in the second direction by the pair of second linear guides, and the moving member is moved in the second direction by rotating each arm of the parallel link mechanism.

上記のように構成された像ぶれ補正装置１において、第１の駆動コイル１７に電流が供給されると、第１の駆動マグネット１２との関係において、供給された電流の方向に応じて左方又は右方への推力が第１の駆動部材１５に付与される。第１の駆動部材１５に左方又は右方への推力が付与されると、該第１の駆動部材１５と移動部材３が一体となって固定部材２に対して第１の方向へ移動される。このとき第１の駆動部材１５は第１のガイド軸７に案内されて第１の方向へ移動され、移動部材３は第２の駆動部材２０の第２の連結部２１に案内されて第１の方向へ移動される。   In the image blur correction device 1 configured as described above, when a current is supplied to the first drive coil 17, the left side of the first drive magnet 12 depends on the direction of the supplied current. Alternatively, a rightward thrust is applied to the first drive member 15. When a leftward or rightward thrust is applied to the first drive member 15, the first drive member 15 and the moving member 3 are moved together in the first direction with respect to the fixed member 2. The At this time, the first driving member 15 is guided by the first guide shaft 7 and moved in the first direction, and the moving member 3 is guided by the second connecting portion 21 of the second driving member 20 and is moved to the first direction. Moved in the direction of.

また、第２の駆動コイル２２に電流が供給されると、第２の駆動マグネット１４との関係において、供給された電流の方向に応じて上方又は下方への推力が第２の駆動部材２０に付与される。第２の駆動部材２０に上方又は下方への推力が付与されると、該第２の駆動部材２０と移動部材３が固定部材２に対して第２の方向へ移動される。このとき第２の駆動部材２０は第２のガイド軸９に案内されて第２の方向へ移動され、移動部材３は第１の駆動部材１５の第１の連結部１６に案内されて第２の方向へ移動される。   Further, when a current is supplied to the second drive coil 22, an upward or downward thrust is applied to the second drive member 20 according to the direction of the supplied current in relation to the second drive magnet 14. Is granted. When an upward or downward thrust is applied to the second drive member 20, the second drive member 20 and the moving member 3 are moved in the second direction with respect to the fixed member 2. At this time, the second driving member 20 is guided by the second guide shaft 9 and moved in the second direction, and the moving member 3 is guided by the first connecting portion 16 of the first driving member 15 and second. Moved in the direction of.

このように、第１の駆動部材１５の第１の連結部１６は移動部材３が第２の方向へ移動するときのガイド部として機能し、第２の駆動部材２０の第２の連結部２１は移動部材３が第１の方向へ移動するときのガイド部として機能する。従って、移動部材３の第１の方向及び第２の方向への移動時における専用のガイド部を別に設ける必要がなく、部品点数の削減及び機構の簡素化を図ることができる。   Thus, the first connecting portion 16 of the first driving member 15 functions as a guide portion when the moving member 3 moves in the second direction, and the second connecting portion 21 of the second driving member 20. Functions as a guide when the moving member 3 moves in the first direction. Therefore, it is not necessary to provide a dedicated guide portion separately when the moving member 3 moves in the first direction and the second direction, and the number of parts can be reduced and the mechanism can be simplified.

上記のように、レンズ２８又は撮像素子を保持する移動部材３が第１の方向及び第２の方向へ移動されることにより、像ぶれが補正される。このとき第１の検出素子１９及び第２の検出素子２４によって移動部材３の固定部材２に対する位置が随時検出され、移動部材３の動作の適正化が図られる。   As described above, the image blur is corrected by moving the lens 28 or the moving member 3 holding the image sensor in the first direction and the second direction. At this time, the position of the moving member 3 with respect to the fixed member 2 is detected by the first detecting element 19 and the second detecting element 24 at any time, and the operation of the moving member 3 is optimized.

第１の検出素子１９と第２の検出素子２４による移動部材３の固定部材２に対する位置検出は、第１の検出素子１９と第２の検出素子２４がそれぞれ第１の駆動マグネット１２と第２の駆動マグネット１４によって発生する磁束の変化を検知することにより行われる。   The first detection element 19 and the second detection element 24 detect the position of the moving member 3 with respect to the fixed member 2 by the first detection element 19 and the second detection element 24, respectively. This is performed by detecting a change in magnetic flux generated by the drive magnet 14.

尚、上記には、第１の駆動部材１５に下方に開口されたコ字状軸受部１５ｃを設け、第２の駆動部材２０に左方に開口されたコ字状軸受部２０ｃを設けた例を示したが、これらのコ字状軸受部１５ｃ、２０ｃをそれぞれ上下方向と左右方向に長い長孔を有する軸受部に変更することが可能である。   In the above example, the first driving member 15 is provided with a U-shaped bearing portion 15c opened downward, and the second driving member 20 is provided with a U-shaped bearing portion 20c opened leftward. However, these U-shaped bearing portions 15c and 20c can be changed to bearing portions having long holes in the vertical direction and the horizontal direction, respectively.

また、移動部材３に上方に開口された第１のコ字状軸受部２６ａと右方に開口されたコ字状軸受部２６ｂ、２６ｂを設けた例を示したが、これらのコ字状軸受部２６ａ、２６ｂ、２６ｂをそれぞれ上下方向と左右方向に長い長孔を有する軸受部に変更することが可能である。   Moreover, although the example which provided the 1st U-shaped bearing part 26a opened upwards in the moving member 3 and the U-shaped bearing parts 26b and 26b opened rightward was shown, these U-shaped bearings were shown. The portions 26a, 26b, and 26b can be changed to bearing portions having long holes that are long in the vertical direction and the horizontal direction, respectively.

上記したように、像ぶれ補正装置１にあっては、第１の方向へ一体になって移動される移動部材３と第１の駆動部材１５が共通の第１のガイド軸７に支持され、第２の方向へ一体になって移動される移動部材３と第２の駆動部材２０が共通の第２のガイド軸９に支持されている。   As described above, in the image blur correction device 1, the moving member 3 and the first driving member 15 that are moved together in the first direction are supported by the common first guide shaft 7, The movable member 3 and the second drive member 20 that are moved together in the second direction are supported by a common second guide shaft 9.

従って、特に、移動部材３と第１の駆動部材１５を第１のガイド軸７によって支持し、移動部材３と第２の駆動部材２０を第２のガイド軸９によって支持することにより、移動部材３の光軸方向に直交する方向における円滑な移動動作を確保することができ、部品点数の削減及び機構の簡素化を図ることができる。   Therefore, in particular, the moving member 3 and the first driving member 15 are supported by the first guide shaft 7, and the moving member 3 and the second driving member 20 are supported by the second guide shaft 9, thereby moving the moving member 3 and the first driving member 15. 3 can be ensured in a direction orthogonal to the direction of the optical axis 3, and the number of parts can be reduced and the mechanism can be simplified.

また、移動部材３の光軸方向に直交する方向における円滑な移動動作を確保することができるため、移動部材３の光軸方向に直交する面内における位置精度が向上し、ぶれ補正の精度の向上を図ることができる。   Further, since the smooth movement operation in the direction orthogonal to the optical axis direction of the moving member 3 can be ensured, the positional accuracy in the plane orthogonal to the optical axis direction of the moving member 3 is improved, and the accuracy of blur correction is improved. Improvements can be made.

さらに、移動部材３と第１の駆動部材１５が第１のガイド軸７に支持され、移動部材３と第２の駆動部材２０が第２のガイド軸９に支持されているため、部品点数の削減を図ることができる。   Furthermore, since the moving member 3 and the first driving member 15 are supported by the first guide shaft 7 and the moving member 3 and the second driving member 20 are supported by the second guide shaft 9, the number of parts is reduced. Reduction can be achieved.

さらにまた、第１の駆動部材１５が第１の駆動手段によって移動され、第２の駆動部材２０が第２の駆動手段によって移動され、第１の駆動手段と第２の駆動手段が各別の第１の駆動部材１５と第２の駆動部材２０を移動させる構成とされている。従って、第１の駆動手段と第２の駆動手段の駆動力が最低限で済み、第１の駆動手段と第２の駆動手段の小型化及び省電力化を図ることができる。   Furthermore, the first drive member 15 is moved by the first drive means, the second drive member 20 is moved by the second drive means, and the first drive means and the second drive means are different from each other. The first drive member 15 and the second drive member 20 are configured to move. Therefore, the driving force of the first driving means and the second driving means is minimal, and the first driving means and the second driving means can be reduced in size and power can be saved.

また、移動部材３と第１の駆動部材１５が独立して設けられ、移動部材３と第２の駆動部材２０が独立して設けられているため、第１の駆動部材１５の第１のガイド軸７と第１のサブガイド軸８に対する組付精度及び第２の駆動部材２０の第２のガイド軸９と第２のサブガイド軸１０に対する組付精度が移動部材３の位置精度に影響しない。従って、移動部材３に保持されたレンズ２８又は撮像素子の良好な光学性能を確保することができると共に第１の駆動部材１５の第１のガイド軸７と第１のサブガイド軸８に対する組付精度及び第２の駆動部材２０の第２のガイド軸９と第２のサブガイド軸１０に対する組付精度の緩和を図ることができる。   Further, since the moving member 3 and the first driving member 15 are provided independently, and the moving member 3 and the second driving member 20 are provided independently, the first guide of the first driving member 15 is provided. The assembly accuracy with respect to the shaft 7 and the first sub guide shaft 8 and the assembly accuracy with respect to the second guide shaft 9 and the second sub guide shaft 10 of the second drive member 20 do not affect the positional accuracy of the moving member 3. . Accordingly, it is possible to ensure good optical performance of the lens 28 or the image pickup device held by the moving member 3 and to assemble the first driving member 15 to the first guide shaft 7 and the first sub guide shaft 8. The accuracy and the assembly accuracy of the second drive member 20 with respect to the second guide shaft 9 and the second sub guide shaft 10 can be relaxed.

さらに、像ぶれ補正装置１は、二つの移動部材が光軸方向に重なって配置されておらず、一方の移動部材が第１の方向へ移動し他方の移動部材が一方の移動部材と一体となって第２の方向へ移動するような構成とされていない。従って、固定部材に対する一方の移動部材の組付精度と一方の移動部材に対する他方の移動部材の組付精度が加算されて組付精度の低下を来たすような構成とされていないため、移動部材３のガタツキや傾きの発生を抑制して光学性能の向上を図ることができる。   Further, in the image blur correction apparatus 1, two moving members are not arranged to overlap each other in the optical axis direction, one moving member moves in the first direction, and the other moving member is integrated with one moving member. Therefore, it is not configured to move in the second direction. Therefore, since the assembly accuracy of one moving member with respect to the fixed member and the assembly accuracy of the other moving member with respect to one moving member are not added, the assembly accuracy is not lowered. The optical performance can be improved by suppressing the occurrence of rattling and tilting.

尚、固定部材２が部材支持部４と該部材支持部４から側方及び下方へ突出された第１の配置部５と第２の配置部６によって構成されているため、第１の配置部５の下方かつ第２の配置部６の側方に固定部材２の部分が存在しない。従って、第１の配置部５の下方かつ第２の配置部６の側方に、像ぶれ補正装置１以外の他の部材を配置することが可能であり、スペースの有効活用による小型化を図ることができる。   In addition, since the fixing member 2 is comprised by the 1st arrangement | positioning part 5 and the 2nd arrangement | positioning part 6 which protruded from the member support part 4 and this member support part 4 to the side and the downward direction, it is the 1st arrangement part. There is no portion of the fixing member 2 below 5 and on the side of the second arrangement portion 6. Therefore, it is possible to dispose other members other than the image blur correction device 1 below the first disposing unit 5 and on the side of the second disposing unit 6, and achieve miniaturization by effectively using the space. be able to.

また、部材支持部４の上側と右側に固定部材２の部品が存在しない。従って、部材支持部４の上側と右側の概略光軸を中心に２７０°の範囲に像ぶれ補正装置１以外の他のアイリス等の部材を配置することができ、光軸方向において重ねることにより小型化を図ることができる。   Further, there are no parts of the fixing member 2 on the upper side and the right side of the member support portion 4. Therefore, other members such as an iris other than the image blur correction device 1 can be arranged in a range of 270 ° around the approximate optical axes on the upper side and the right side of the member support portion 4 and can be reduced in size by overlapping in the optical axis direction. Can be achieved.

さらに、像ぶれ補正装置１にあっては、移動部材３と第１の駆動部材１５及び第２の駆動部材２０とが独立して設けられているため、例えば、移動部材３のみを撮像装置に応じた他のタイプの移動部材に交換することが可能であり、移動部材以外の他の部品を共通化して製造コストの低減を図ることができる。   Furthermore, in the image blur correction apparatus 1, since the moving member 3, the first driving member 15, and the second driving member 20 are provided independently, for example, only the moving member 3 is included in the imaging apparatus. It is possible to replace with other types of moving members according to the requirements, and it is possible to reduce the manufacturing cost by sharing other parts other than the moving members.

以下に、像ぶれ補正装置１における第１の駆動マグネット１２と第２の駆動マグネット１４から受ける磁力の変動について説明する（図７乃至図９参照）。尚、磁力は移動部材３が第１の方向に移動された場合と第２の方向へ移動された場合とで同様に変動するため、以下には、例として、移動部材３が第１の方向へ移動された場合における磁力の変動について説明する。   Hereinafter, fluctuations in magnetic force received from the first drive magnet 12 and the second drive magnet 14 in the image blur correction apparatus 1 will be described (see FIGS. 7 to 9). The magnetic force varies in the same manner when the moving member 3 is moved in the first direction and when the moving member 3 is moved in the second direction. Therefore, as an example, the moving member 3 is moved in the first direction. A description will be given of the fluctuation of the magnetic force when moved to.

図７は、移動部材３が移動範囲における中央、即ち、基準位置にある状態を示し、図８は、移動部材３が基準位置から一方へ移動したときの状態を示し、図９は、移動部材３が基準位置から他方へ移動したときの状態を示す。   7 shows a state in which the moving member 3 is in the center of the moving range, that is, at the reference position, FIG. 8 shows a state when the moving member 3 has moved from the reference position to one side, and FIG. 3 shows a state when moving from the reference position to the other.

図７乃至図９の各図において、上側の図は第１の駆動マグネット１２に対する第１の駆動コイル１７等の位置を示す図であり、下側の図は第１の駆動マグネット１２によって発生する磁束密度を示す図である。下側の図において、斜線部分は第１の駆動コイル１７が第１の駆動マグネット１２から受ける磁力（第１の駆動マグネット１２の推力）を示す。また、各図に点線で示す円内におけるＰ点は、移動部材３の第１の方向における移動時に第１の検出素子１９が検出を行う検出位置を示す。   In each of FIGS. 7 to 9, the upper diagram shows the position of the first drive coil 17 and the like with respect to the first drive magnet 12, and the lower diagram is generated by the first drive magnet 12. It is a figure which shows magnetic flux density. In the lower diagram, the hatched portion indicates the magnetic force (the thrust of the first drive magnet 12) that the first drive coil 17 receives from the first drive magnet 12. Further, a point P in a circle indicated by a dotted line in each figure indicates a detection position where the first detection element 19 detects when the moving member 3 moves in the first direction.

第１の駆動コイル１７を巻軸方向が移動部材３の移動方向（第１の方向）となるようにしたときには、図７乃至図９に示すように、第１の駆動マグネット１２をＮ極とＳ極が光軸方向（前後方向）に位置される構成とすることが可能である。従って、磁束密度は移動部材３の移動方向（第１の方向）の両端部で急激に低下するが、両端部以外の部分では略均一な高い値となる。   When the winding direction of the first drive coil 17 is the moving direction (first direction) of the moving member 3, as shown in FIGS. 7 to 9, the first drive magnet 12 is set to the N pole. It is possible to adopt a configuration in which the S pole is positioned in the optical axis direction (front-rear direction). Accordingly, the magnetic flux density rapidly decreases at both ends of the moving member 3 in the moving direction (first direction), but becomes a substantially uniform high value at portions other than both ends.

図８に示すように、移動部材３が基準位置から一方へ移動された場合に、第１の駆動コイル１７が受ける磁力はＡの領域（梨子地を付した領域）分だけ僅かに低下するが、移動部材３が基準位置にある場合と略同じである。同様に、図９に示すように、移動部材３が基準位置から他方へ移動された場合にも、第１の駆動コイル１７が受ける磁力はＢの領域（梨子地を付した領域）分だけ僅かに低下するが、移動部材３が基準位置にある場合と略同じである。   As shown in FIG. 8, when the moving member 3 is moved from the reference position to one side, the magnetic force received by the first drive coil 17 is slightly reduced by an area A (area with a pear ground). This is substantially the same as when the moving member 3 is at the reference position. Similarly, as shown in FIG. 9, even when the moving member 3 is moved from the reference position to the other side, the magnetic force received by the first drive coil 17 is only a small amount corresponding to the region B (region with pear paste). However, it is substantially the same as when the moving member 3 is at the reference position.

このように、第１の駆動コイル１７の巻軸方向を移動部材３の移動方向である第１の方向に一致させることにより、移動部材３の移動時において第１の駆動コイル１７が受ける磁力の変動が小さく、移動部材３の第１の方向における動作の円滑化及び動作の信頼性を図ることができる。   Thus, by making the winding axis direction of the first drive coil 17 coincide with the first direction that is the movement direction of the moving member 3, the magnetic force received by the first drive coil 17 during the movement of the moving member 3 is increased. The fluctuation is small, and the movement of the moving member 3 in the first direction can be facilitated and the reliability of the movement can be achieved.

また、同様に、第２の駆動コイル２２の巻軸方向を移動部材３の移動方向である第２の方向に一致させることによっても、移動部材３の移動時において第２の駆動コイル２２が受ける磁力の変動が小さく、移動部材３の第２の方向における動作の円滑化及び動作の信頼性を図ることができる。   Similarly, the second drive coil 22 is also received when the moving member 3 is moved by matching the winding axis direction of the second drive coil 22 with the second direction, which is the moving direction of the moving member 3. The fluctuation of the magnetic force is small, and the movement of the moving member 3 in the second direction can be smoothed and the reliability of the movement can be achieved.

図１０は、第１の駆動マグネット１２によって発生する磁束密度を移動部材３の移動方向側から見た状態で示す図である。上側のグラフ図は第１の駆動コイル１７の第１の方向における中央での磁束密度を示し、下側のグラフ図は第１の検出素子１９の第１の方向における中央での磁束密度を示す。   FIG. 10 is a diagram illustrating the magnetic flux density generated by the first drive magnet 12 as viewed from the moving direction side of the moving member 3. The upper graph shows the magnetic flux density at the center of the first drive coil 17 in the first direction, and the lower graph shows the magnetic flux density at the center of the first detection element 19 in the first direction. .

第１の検出素子１９による移動部材３の固定部材２に対する位置検出は、上記したように、第１の検出素子１９が第１の駆動マグネット１２によって発生する磁束の変化を検知することにより行われる。従って、第１の駆動部材１５が第２の方向にも移動可能な構成とされていると第１の検出素子１９も第２の方向へ移動され、第１の検出素子１９の検出位置が第２の方向にシフトし、例えば、図１０のＲ点が検出位置になってしまう。   The position detection of the moving member 3 with respect to the fixed member 2 by the first detection element 19 is performed when the first detection element 19 detects a change in magnetic flux generated by the first drive magnet 12 as described above. . Therefore, if the first drive member 15 is configured to be movable in the second direction, the first detection element 19 is also moved in the second direction, and the detection position of the first detection element 19 is the first position. For example, the point R in FIG. 10 becomes the detection position.

しかしながら、像ぶれ補正装置１は第１の駆動部材１５が第１の方向にのみ移動される構成とされているため、第１の検出素子１９の検出位置は、常に、図１０に示すＱ点となる。Ｒ点とＱ点では磁束の変化状態が異なるため、Ｒ点が検出位置となった場合には、磁束密度Ｑ−Ｒ分だけ第１の検出素子１９の検出に誤差を及ぼすが、像ぶれ補正装置１にあっては、第１の検出素子１９の検出位置が、常に、Ｑ点であるため、検出精度が低下することがなく、第１の検出素子１９における位置検出の精度の向上を図ることができる。   However, since the image blur correction apparatus 1 is configured such that the first drive member 15 is moved only in the first direction, the detection position of the first detection element 19 is always at the point Q shown in FIG. It becomes. Since the change state of the magnetic flux is different between the R point and the Q point, when the R point becomes the detection position, an error is caused in the detection of the first detection element 19 by the magnetic flux density QR, but the image blur correction is performed. In the apparatus 1, since the detection position of the first detection element 19 is always the Q point, the detection accuracy does not decrease, and the position detection accuracy of the first detection element 19 is improved. be able to.

また、同様に、第２の駆動部材２０が第２の方向にのみ移動可能とされているため、第２の検出素子２４の検出位置が第１の方向にシフトすることがなく、第２の検出素子２４における位置検出の精度の向上も図ることができる。   Similarly, since the second drive member 20 is movable only in the second direction, the detection position of the second detection element 24 does not shift in the first direction, and the second The accuracy of position detection in the detection element 24 can also be improved.

さらに、第１の駆動部材１５が第１の方向にのみ移動可能とされているため、第１のヨーク１１の突面部１１ｂの第２の方向における両面と第１の駆動コイル１７の内面との間隔Ｈ、Ｈ（図１１参照）を小さくすることができ、その分、像ぶれ補正装置１の小型化を図ることができる。   Furthermore, since the first drive member 15 is movable only in the first direction, the both surfaces of the projecting surface portion 11b of the first yoke 11 in the second direction and the inner surface of the first drive coil 17 are arranged. The intervals H and H (see FIG. 11) can be reduced, and the image blur correction apparatus 1 can be downsized accordingly.

さらにまた、第１のヨーク１１の突面部１１ｂの第２の方向における両面と第１の駆動コイル１７の内面との間隔Ｈ、Ｈを小さくすることにより、コイルの１周当たりの長さを短くすることができ、コイルの抵抗値を小さくすることが可能であり、その分、電流を多く流せるため推力を高めてぶれ補正の精度の向上を図ることができる。   Furthermore, by reducing the distances H and H between the both surfaces in the second direction of the projecting surface portion 11b of the first yoke 11 and the inner surface of the first drive coil 17, the length per one turn of the coil is shortened. Thus, the resistance value of the coil can be reduced, and a larger amount of current can be flowed accordingly, so that the thrust can be increased and the accuracy of shake correction can be improved.

また、同様に、第２の駆動部材２０が第２の方向にのみ移動可能とされているため、第２のヨーク１３の突面部１３ｂの第１の方向における両面と第２の駆動コイル２２の内面との間隔も小さくすることができ、その分、像ぶれ補正装置１の小型化を図ることができる。   Similarly, since the second drive member 20 is movable only in the second direction, both surfaces of the projecting surface portion 13b of the second yoke 13 in the first direction and the second drive coil 22 The distance from the inner surface can also be reduced, and the image blur correction device 1 can be reduced in size accordingly.

＜変形例＞
次に、像ぶれ補正装置の各変形例について説明する（図１２乃至図２９参照）。 <Modification>
Next, modifications of the image blur correction device will be described (see FIGS. 12 to 29).

尚、以下に示す第１の変形例に係る像ぶれ補正装置１Ａは、上記した像ぶれ補正装置１と比較して、駆動コイルの巻軸方向が異なることのみが相違し、第２の変形例に係る像ぶれ補正装置１Ｂは、像ぶれ補正装置１と比較して、駆動手段が異なることのみが相違する。また、第３の変形例乃至第５の変形例に係る像ぶれ補正装置１Ｃ、１Ｄ、１Ｅは、何れも上記した像ぶれ補正装置１と比較して、ガイド軸に対する移動部材の支持状態のみが相違する。従って、以下の各変形例の説明においては、像ぶれ補正装置１と比較して異なる部分についてのみ詳細に説明をし、その他の部分については像ぶれ補正装置１における同様の部分に付した符号と同じ符号を付して説明は省略する。   The image blur correction apparatus 1A according to the first modification described below is different from the image blur correction apparatus 1 described above only in the direction of the winding axis of the drive coil, and the second modification. The image blur correction apparatus 1B according to the second embodiment differs from the image blur correction apparatus 1 only in that the driving unit is different. In addition, the image blur correction apparatuses 1C, 1D, and 1E according to the third to fifth modifications are all in only the support state of the moving member with respect to the guide shaft as compared with the image blur correction apparatus 1 described above. Is different. Therefore, in the following description of each modification, only the parts that are different from the image blur correction apparatus 1 will be described in detail, and the other parts will be denoted by the reference numerals assigned to the same parts in the image blur correction apparatus 1. The same reference numerals are given and description thereof is omitted.

＜第１の変形例＞

従って、移動部材３の光軸方向に直交する方向における円滑な移動動作を確保することができる。   Therefore, a smooth movement operation in a direction orthogonal to the optical axis direction of the moving member 3 can be ensured.

また、移動部材３の光軸方向に直交する方向における円滑な移動動作を確保することができるため、移動部材３の光軸方向に直交する面内における位置精度が向上し、ぶれ補正の精度の向上を図ることができる。   Further, since the smooth movement operation in the direction orthogonal to the optical axis direction of the moving member 3 can be ensured, the positional accuracy in the plane orthogonal to the optical axis direction of the moving member 3 is improved, and the accuracy of blur correction is improved. Improvements can be made.

さらに、移動部材３と第１の駆動部材１５が第１のガイド軸７に支持され、移動部材３と第２の駆動部材２０が第２のガイド軸９に支持されているため、部品点数の削減を図ることができる。   Furthermore, since the moving member 3 and the first driving member 15 are supported by the first guide shaft 7 and the moving member 3 and the second driving member 20 are supported by the second guide shaft 9, the number of parts is reduced. Reduction can be achieved.

以下に、像ぶれ補正装置１Ａにおける第１の駆動マグネット１２と第２の駆動マグネット１４から受ける磁力の変動について説明する（図１５乃至図１７参照）。尚、磁力は移動部材３が第１の方向に移動された場合と第２の方向へ移動された場合とで同様に変動するため、以下には、例として、移動部材３が第１の方向へ移動された場合における磁力の変動について説明する。   Hereinafter, fluctuations in magnetic force received from the first drive magnet 12 and the second drive magnet 14 in the image blur correction apparatus 1A will be described (see FIGS. 15 to 17). The magnetic force varies in the same manner when the moving member 3 is moved in the first direction and when the moving member 3 is moved in the second direction. Therefore, as an example, the moving member 3 is moved in the first direction. A description will be given of the fluctuation of the magnetic force when moved to.

図１５は、移動部材３が移動範囲における中央、即ち、基準位置にある状態を示し、図１６は、移動部材３が基準位置から一方へ移動したときの状態を示し、図１７は、移動部材３が基準位置から他方へ移動したときの状態を示す。   15 shows a state in which the moving member 3 is in the center of the moving range, that is, at the reference position, FIG. 16 shows a state when the moving member 3 has moved from the reference position to one side, and FIG. 3 shows a state when moving from the reference position to the other.

図１５乃至図１７の各図において、上側の図は第１の駆動マグネット１２に対する第１の駆動コイル１７Ａ等の位置を示す図であり、下側の図は第１の駆動マグネット１２によって発生する磁束密度を示す図である。下側の図において、斜線部分は第１の駆動コイル１７Ａが第１の駆動マグネット１２から受ける磁力（第１の駆動マグネット１２の推力）を示す。また、各図に点線で示す円内におけるＰ点は、移動部材３の第１の方向における移動時に第１の検出素子１９Ａが検出を行う検出位置を示す。   In each of FIGS. 15 to 17, the upper diagram shows the position of the first drive coil 17 </ b> A and the like with respect to the first drive magnet 12, and the lower diagram is generated by the first drive magnet 12. It is a figure which shows magnetic flux density. In the lower diagram, the hatched portion indicates the magnetic force (the thrust of the first drive magnet 12) received by the first drive coil 17A from the first drive magnet 12. Further, a point P in a circle indicated by a dotted line in each figure indicates a detection position where the first detection element 19A detects when the moving member 3 moves in the first direction.

第１の駆動コイル１７Ａを巻軸方向が光軸方向となるようにしたときには、図１５乃至図１７に示すように、第１の駆動マグネット１２を第１の駆動部材１５の移動方向においてＮ極とＳ極に着磁する必要がある。従って、磁束密度は各極の中心で最も高く各極の中心から第１の方向において遠去かるに従って小さくなる。   When the winding direction of the first drive coil 17A is the optical axis direction, the first drive magnet 12 is moved to the N pole in the moving direction of the first drive member 15 as shown in FIGS. It is necessary to magnetize the S pole. Therefore, the magnetic flux density is the highest at the center of each pole and decreases as the distance from the center of each pole in the first direction increases.

図１６に示すように、移動部材３が基準位置から一方へ移動された場合及び他方へ移動された場合に、第１の駆動コイル１７Ａが受ける磁力は低下するが、像ぶれ補正装置１Ａにあっては、第１の駆動部材１５を第１の方向へ移動させる磁力として必要な磁力が確保されている。但し、像ぶれ補正装置１のように第１の駆動コイル１７の巻軸方向を第１の方向とし、第２の駆動コイル２２の巻軸方向を第２の方向とした場合よりは磁力の変動が大きい。   As shown in FIG. 16, when the moving member 3 is moved from the reference position to one side and moved to the other side, the magnetic force received by the first drive coil 17A is reduced, but the image blur correction apparatus 1A is affected. Thus, a necessary magnetic force is secured as a magnetic force for moving the first driving member 15 in the first direction. However, as in the case of the image blur correction apparatus 1, the magnetic force fluctuation is larger than when the winding direction of the first drive coil 17 is the first direction and the winding direction of the second drive coil 22 is the second direction. Is big.

また、同様に、移動部材３が第２の方向において基準位置から一方へ移動された場合及び他方へ移動された場合にも、第２の駆動コイル２２Ａが受ける磁力は低下するが、像ぶれ補正装置１Ａにあっては、第２の駆動部材２２Ａを第２の方向へ移動させる磁力として必要な磁力が確保されている。   Similarly, when the moving member 3 is moved from the reference position to one side in the second direction and also moved to the other side, the magnetic force received by the second drive coil 22A is reduced, but image blur correction is performed. In the apparatus 1A, a necessary magnetic force is secured as a magnetic force for moving the second driving member 22A in the second direction.
