Description

本発明は、監視カメラ装置、ビデオカメラ装置およびデジタルスチルカメラ装置等の撮像素子を有する撮影装置に関し、特に、撮像素子のあおり角度の調整を行う撮像素子のあおり調整装置およびそれを用いた撮影装置に関する。   The present invention relates to an imaging device having an imaging element such as a surveillance camera device, a video camera device, and a digital still camera device, and more particularly to an imaging device tilt adjustment device that adjusts the tilt angle of the imaging device and an imaging device using the same. About.

ＣＣＤやＣＭＯＳ等の撮像素子を有する撮影装置においては、一般的に、撮像素子がレンズの光軸方向に対して直交した状態であることが、鮮鋭な画像を撮影するために望ましい。   In an imaging apparatus having an image sensor such as a CCD or CMOS, it is generally desirable for the image sensor to be in a state orthogonal to the optical axis direction of the lens in order to capture a sharp image.

しかしながら、撮像素子を取り付ける際に、撮像素子をレンズの光軸方向に対して直交させるように調整しておいたとしても、実際には部品寸法のばらつきや組み立て時のばらつき等による微妙なずれが発生し（以下、このような微妙なずれが発生している場合のことを「あおり角度」を有する場合と記し、直交する状態からの差分の角度を「あおり角度」と記し、このあおり角度をなくするように調整することを「あおり角度」の調整と記す）、このずれが画像の部分的なぼけ等を惹き起こし、画質に大きな悪影響を与える可能性があるという課題があった。   However, even when the image sensor is adjusted so that it is orthogonal to the optical axis direction of the lens when the image sensor is mounted, there is actually a slight shift due to variations in component dimensions and variations during assembly. (Hereinafter, the case where such a slight deviation has occurred is described as having a “tilt angle”, and the difference angle from the orthogonal state is denoted as “tilt angle”. The adjustment so as to eliminate it is referred to as the adjustment of the “tilt angle”), and this deviation causes a partial blur of the image, and there is a problem that the image quality may be greatly adversely affected.

従来から、このような課題を解決するために、様々な提案がなされており、例えば、第１の提案として、撮像素子を支持するためのマウントと、後部鏡筒に固定された鋼球と、マウントと後部鏡筒との間に光軸と直交する方向に配置された調整ねじとを備え、調整ねじのねじ込み程度を変えることにより、鋼球を支点として後部鏡筒に対するマウントの角度を変え、撮像素子の傾きを補正する技術が提案されている（例えば、特許文献１を参照。）。   Conventionally, various proposals have been made to solve such a problem.For example, as a first proposal, a mount for supporting an image sensor, a steel ball fixed to a rear barrel, With an adjustment screw arranged in a direction perpendicular to the optical axis between the mount and the rear lens barrel, by changing the screwing degree of the adjustment screw, the angle of the mount relative to the rear lens barrel is changed with the steel ball as a fulcrum, A technique for correcting the tilt of the image sensor has been proposed (see, for example, Patent Document 1).

また、第２の提案として、撮像素子を固定する可動板、その可動板を突起部によって保持する固定板、ならびに、可動板および固定板を係合する垂直調整用および垂直調整用の調整ねじを備え、調整ねじを回転させることによって、撮像素子の垂直方向および水平方向のあおり角度の調整を行うことのできる技術が提案されている（例えば、特許文献２を参照。）。
特開２００５−１１７２５３号公報 特開平８−２４８４６５号公報 Further, as a second proposal, there are provided a movable plate for fixing the image pickup device, a fixed plate for holding the movable plate by a protrusion, and an adjustment screw for vertical adjustment and vertical adjustment for engaging the movable plate and the fixed plate. A technique has been proposed that can adjust the vertical and horizontal tilt angles of the image sensor by rotating the adjusting screw (see, for example, Patent Document 2).
JP 2005-117253 A JP-A-8-248465

しかしながら、まず、第１の提案における技術については、撮像素子の撮像面の中心とあおり調整の支点となる鋼球の配置された位置とが離れているので、あおり調整を行った場合に、撮像面の中心と光軸とが大きくずれてしまい、画像に悪影響を与える可能性があった。   However, with regard to the technique in the first proposal, first, since the center of the imaging surface of the image sensor is separated from the position where the steel ball serving as the fulcrum adjustment fulcrum is located, imaging is performed when tilt adjustment is performed. There is a possibility that the center of the surface and the optical axis are greatly deviated to adversely affect the image.

また、第２の提案における技術においては、撮像素子の固定された可動板と可動板を保持する固定板とが、可動部に設けられた凹部に当接している突起部によって保持されているので、あおり調整を行った場合に、突起部と凹部とが当接する位置がずれる可能性があり、この位置がずれた場合には、滑らかにあおり角度を調整することができず、正確なあおり調整が難しいという可能性があった。   In the technique in the second proposal, the movable plate to which the image sensor is fixed and the fixed plate for holding the movable plate are held by the protrusions that are in contact with the recesses provided in the movable portion. When tilt adjustment is performed, there is a possibility that the position where the projection and the concave portion come into contact with each other. If this position is shifted, the tilt angle cannot be adjusted smoothly, and accurate tilt adjustment is possible. There was a possibility that it was difficult.

本発明はこのような課題に鑑みてなされたものであり、あおり調整を行った場合に、撮像面の中心と光軸とが大きくずれることがなく、滑らかにあおり角度を調整することの可能な撮像素子のあおり調整装置およびそれを用いた撮影装置を提供することを目的とする。   The present invention has been made in view of such a problem.

An object of the present invention is to provide a tilt adjustment device for an image sensor and a photographing device using the device.

Is provided with a movable portion-side recess 64. The movable part side concave part 64 is formed with a concave part having a conical taper at the bottom.

A pair of heat radiation plate mounting bosses 62 for mounting the heat radiation plate 91 of the image sensor 100 is provided on the side opposite to the side where the column portion 63 of the movable portion 60 is provided.

さらに、図５に示したように、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０においては、その固定部５０の側から、長穴部５１を通って、可動部６０の穴部６６に対して、一対の調整ねじ部２００が取り付けられるとともに、各調整ねじ部２００の球体部１１０の中心位置に対して反対側に、一対の保持ねじ部２１０が弾性部２１１を介して取り付けられている。ここで、弾性部２１１としては、例えばつるまきばねを用いることができる。また、調整ねじ部２００の根元の部分は、球面上に加工された球面部２０１となっている。   Furthermore, as shown in FIG. 5, in the image sensor holding unit 90 of the image sensor drive device 1 according to the embodiment of the present invention, the movable unit 60 passes from the fixed unit 50 side through the slot 51. A pair of adjustment screw portions 200 are attached to the hole portions 66 of the other, and a pair of holding screw portions 210 are provided on the opposite side of the center position of the spherical body portion 110 of each adjustment screw portion 200 via the elastic portion 211.

このような構成により、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０を用いれば、可動部６０に取り付けられた撮像素子１００のあおり角度の調整を行うことができる。ここで、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０を用いて撮像素子１００のあおり角度の調整を行うことのできる理由について詳細に説明する。   With such a configuration, the tilt angle of the image sensor 100 attached to the movable unit 60 can be adjusted by using the image sensor holding unit 90 of the image sensor driving device 1 according to the embodiment of the present invention. Here, the reason why the tilt angle of the image sensor 100 can be adjusted using the image sensor holding unit 90 of the image sensor driving device 1 according to the embodiment of the present invention will be described in detail.

図６は、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０によって撮像素子１００のあおり角度調整が可能な理由を説明するための図であり、図６（ａ）は、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０の図１（ｂ）におけるＹ１−Ｙ２断面を示す図であり、図６（ｂ）は、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０の図６（ａ）におけるＡ１−Ａ２断面を示す図である。なお、図６（ａ）および図６（ｂ）においては、ともに撮像素子１００の垂直方向（図面中において、Ｘ軸を中心とした回転方向）のあおり角度を調整する例を示す。   FIG. 6 is a diagram for explaining the reason why the tilt angle of the image sensor 100 can be adjusted by the image sensor holding unit 90 of the image sensor driving device 1 according to the embodiment of the present invention. It is a figure which shows the Y1-Y2 cross section in FIG.1 (b) of the image pick-up element holding | maintenance part 90 of the image pick-up element drive device 1 in embodiment of this invention, FIG.6 (b) is the imaging in embodiment of this invention. It is a figure which shows the A1-A2 cross section in Fig.6 (a) of the image pick-up element holding | maintenance part 90 of the element drive device 1. FIG. 6A and 6B both show examples of adjusting the tilt angle in the vertical direction of the image sensor 100 (the rotation direction about the X axis in the drawing).

まず、図６（ａ）に示したように、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０は、固定部５０が、調整ねじ部２００および保持ねじ部２１０によって、可動部６０に取り付けられた状態である。また、可動部６０と固定部５０とは、前述のように球体部１１０を介して接続されており、球体部１１０は回転可能に保持されていることから、調整ねじ部２００を調整することにより、可動部６０は固定部５０に対して、球体部１１０の球の中心位置を支点として、垂直方向に回動することが可能となる。また、可動部側凹部６４および固定部側凹部５３はそれぞれ、前述のように、円錐形状のテーパを有し、球体部１１０を滑りよく保持することができる。   First, as shown in FIG. 6A, in the image sensor holding unit 90 of the image sensor drive device 1 in the embodiment of the present invention, the fixing unit 50 is movable by the adjustment screw unit 200 and the holding screw unit 210. It is in a state attached to the part 60. Moreover, since the movable part 60 and the fixed part 50 are connected via the sphere part 110 as described above and the sphere part 110 is rotatably held, the adjustment screw part 200 is adjusted. The movable part 60 can be rotated with respect to the fixed part 50 in the vertical direction with the center position of the sphere 110 as a fulcrum. Further, as described above, each of the movable portion side recessed portion 64 and the fixed portion side recessed portion 53 has a conical taper and can hold the spherical body portion 110 in a slippery manner.

また、図６（ａ）に示したように、調整ねじ部２００が固定部５０に貫通する部分には、あおり角度を調整すべき方向、すなわちＹ軸方向に長い長穴部５１が形成されているので、調整ねじ部２００と固定部５０とがＹ軸方向に接触することがなく、図６（ｂ）に示したように、Ｘ軸方向には、調整ねじ部２００と面取り部５２とが接触することによって、調整ねじ部２００と固定部５０とが接続されている。また、図６（ａ）に示したように、保持ねじ部２１０は、弾性部２１１を介して固定部５０を締結しているので、固定部５０は図６（ａ）における下側の部分では、弾性的に可動部６０に取り付けられていることとなる。   In addition, as shown in FIG. 6A, a long hole 51 that is long in the direction in which the tilt angle should be adjusted, that is, the Y-axis direction, is formed in the portion where the adjustment screw portion 200 penetrates the fixing portion 50. Therefore, the adjusting screw part 200 and the fixing part 50 do not contact in the Y-axis direction, and as shown in FIG. 6B, the adjusting screw part 200 and the chamfered part 52 are in the X-axis direction. By making contact, the adjusting screw portion 200 and the fixing portion 50 are connected. Further, as shown in FIG. 6A, since the holding screw portion 210 fastens the fixing portion 50 via the elastic portion 211, the fixing portion 50 is not in the lower portion in FIG. Therefore, it is elastically attached to the movable part 60.

このような構成において、可動部６０に設けられた撮像素子１００の垂直方向のあおり角度調整を行う方法について説明する。図７は、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０において、撮像素子１００の垂直方向のあおり角度調整を行う方法について説明するための図である。   A method of adjusting the tilt angle in the vertical direction of the image sensor 100 provided in the movable unit 60 in such a configuration will be described. FIG. 7 is a diagram for describing a method for adjusting the tilt angle in the vertical direction of the image sensor 100 in the image sensor holding unit 90 of the image sensor drive device 1 according to the embodiment of the present invention.

図７（ａ）に示したように、まず、調整ねじ部２００を締結する方向（例えば、時計回り方向）に回転させた場合には、調整ねじ部２００が可動部６０により深く締結されて、図７（ａ）における上側の部分において、可動部６０と固定部５０との距離が接近する。このとき、固定部５０は前述のように、面方向を維持した状態で保持されているので、図７（ａ）に示したように、可動部６０が球体部１１０の中心位置を支点として回動して、その上部で固定部５０に接近することとなる。一方で、図７（ａ）における下側の部分においては、可動部６０と固定部５０とが離間するように、可動部６０が球体部１１０の中心を支点として回動するので、可動部６０の固定部５０に対する面方向を、Ｘ軸方向を中心として回転（図面中におけるＡ方向）させることができる。   As shown in FIG. 7A, first, when the adjustment screw part 200 is rotated in the fastening direction (for example, clockwise direction), the adjustment screw part 200 is deeply fastened by the movable part 60, In the upper part in FIG. 7A, the distance between the movable part 60 and the fixed part 50 approaches. At this time, as described above, since the fixed portion 50 is held in a state in which the surface direction is maintained, as shown in FIG. 7A, the movable portion 60 rotates around the center position of the spherical portion 110 as a fulcrum. It moves and approaches the fixing | fixed part 50 in the upper part. On the other hand, in the lower part in FIG. 7A, the movable part 60 rotates about the center of the spherical part 110 so that the movable part 60 and the fixed part 50 are separated from each other. Can be rotated about the X-axis direction (A direction in the drawing).

なお、このとき、図７（ａ）に示したように、調整ねじ部２００および保持ねじ部２１０は、それぞれ可動部６０に対して垂直を保った状態であり、固定部５０の調整ねじ部２００および保持ねじ部２１０が貫通する部分には、それぞれＹ軸方向に長い長穴部５１が形成されていることから、調整ねじ部２００および保持ねじ部２１０はそれぞれ固定部５０に対して角度を変化させることができる。   At this time, as shown in FIG. 7A, the adjustment screw part 200 and the holding screw part 210 are kept perpendicular to the movable part 60, respectively, and the adjustment screw part 200 of the fixed part 50. Since the elongated holes 51 in the Y-axis direction are formed in the portions through which the holding screw part 210 passes, the adjustment screw part 200 and the holding screw part 210 change the angle with respect to the fixing part 50, respectively. Can be made.

逆に、図７（ｂ）に示したように、調整ねじ部２００を緩める方向（例えば、反時計回り方向）に回転させた場合には、図７（ｂ）の上側において、可動部６０と固定部５０とが離間する方向の力が作用する一方で、図７（ｂ）の下側の部分においては、弾性部２１１の付勢力によって、可動部６０と固定部５０とが接近するように、可動部６０が球体部１１０の中心を支点として回動して、可動部６０の固定部５０に対する面方向を逆方向（図面中におけるＢ方向）に回転させることができる。   On the contrary, as shown in FIG. 7B, when the adjustment screw portion 200 is rotated in a loosening direction (for example, counterclockwise direction), the movable portion 60 and the upper portion of FIG. While the force in the direction in which the fixed portion 50 is separated acts, the movable portion 60 and the fixed portion 50 are brought close to each other by the urging force of the elastic portion 211 in the lower portion of FIG. The movable part 60 can be rotated about the center of the spherical body part 110, and the surface direction of the movable part 60 with respect to the fixed part 50 can be rotated in the reverse direction (the B direction in the drawing).

なお、この場合においても、図７（ｂ）に示したように、調整ねじ部２００および保持ねじ部２１０は、それぞれ可動部６０に対して直立した状態であり、固定部５０の調整ねじ部２００および保持ねじ部２１０が貫通する部分には、それぞれＹ軸方向に長い長穴部５１が形成されていることから、調整ねじ部２００および保持ねじ部２１０はそれぞれ固定部５０に対して角度を変化させることができる。   Even in this case, as shown in FIG. 7B, the adjustment screw portion 200 and the holding screw portion 210 are each in an upright state with respect to the movable portion 60, and the adjustment screw portion 200 of the fixed portion 50. Since the elongated holes 51 in the Y-axis direction are formed in the portions through which the holding screw part 210 passes, the adjustment screw part 200 and the holding screw part 210 change the angle with respect to the fixing part 50, respectively. Can be made.

次に、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０の可動部６０に設けられた撮像素子１００の水平方向のあおり角度調整を行う方法について説明する。図８は、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０において、撮像素子１００の水平方向のあおり角度調整を行う方法について説明するための図である。   Next, a method of adjusting the tilt angle in the horizontal direction of the image sensor 100 provided in the movable unit 60 of the image sensor holding unit 90 of the image sensor driving device 1 according to the embodiment of the present invention will be described. FIG. 8 is a diagram for explaining a method for adjusting the tilt angle in the horizontal direction of the image sensor 100 in the image sensor holding unit 90 of the image sensor drive device 1 according to the embodiment of the present invention.

It is a figure which shows the B1-B2 cross section in Fig.8 (a) of the image pick-up element holding | maintenance part 90 of the image pick-up element drive device 1 in a form. 8A and 8B both show examples of adjusting the tilt angle of the image sensor 100 in the horizontal direction (rotation direction around the Y axis in the drawing).

まず、図８（ａ）に示したように、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０は、固定部５０が、調整ねじ部２００および保持ねじ部２１０によって、可動部６０に取り付けられた状態である。また、可動部６０と固定部５０とは、前述のように球体部１１０を介して接続されており、球体部１１０は回転可能に保持されていることから、可動部６０は固定部５０に対して、水平方向に球体部１１０の中心を支点として回動することが可能となる。また、可動部側凹部６４および固定部側凹部５３はそれぞれ、円錐形状のテーパを有し、球体部１１０を滑りよく保持することができることは前述の通りである。   First, as shown in FIG. 8A, in the image sensor holding unit 90 of the image sensor driving device 1 in the embodiment of the present invention, the fixing unit 50 is movable by the adjustment screw unit 200 and the holding screw unit 210. It is in a state attached to the part 60. In addition, the movable part 60 and the fixed part 50 are connected via the sphere part 110 as described above. Since the sphere part 110 is rotatably held, the movable part 60 is connected to the fixed part 50. Thus, the center of the sphere 110 can be rotated in the horizontal direction as a fulcrum. Further, as described above, each of the movable portion side recessed portion 64 and the fixed portion side recessed portion 53 has a conical taper and can hold the spherical body portion 110 in a slippery manner.

また、図８（ａ）に示したように、調整ねじ部２００が固定部５０と貫通する部分には、あおり角度を調整すべき方向、すなわち、Ｘ軸方向に長い長穴部５１が形成されているので、可動部６０が回動しても接触することがなく、また、図８（ｂ）に示したように、Ｙ軸方向には、面取り部５２と接触することによって、調整ねじ部２００と固定部５０とが接続されている。また、保持ねじ部２１０は、弾性部２１１を介して固定部５０を締結しているので、固定部５０は図８（ａ）における右側の部分で、弾性的に可動部６０に取り付けられている。   As shown in FIG. 8A, a long hole 51 that is long in the direction in which the tilt angle is adjusted, that is, in the X-axis direction, is formed in a portion where the adjustment screw portion 200 penetrates the fixing portion 50. Therefore, even if the movable part 60 rotates, it does not come into contact, and as shown in FIG. 8B, in the Y-axis direction, the adjustment screw part comes into contact with the chamfered part 52. 200 and the fixed part 50 are connected. Further, since the holding screw portion 210 fastens the fixing portion 50 via the elastic portion 211, the fixing portion 50 is elastically attached to the movable portion 60 at the right portion in FIG. .

このような構成において、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０によれば、前述したように、可動部６０に設けられた撮像素子１００の垂直方向のあおり角度調整を行うことができるのと同様に、撮像素子１００の水平方向のあおり角度の調整を行うことが可能である。   In such a configuration, according to the image sensor holding unit 90 of the image sensor driving device 1 in the embodiment of the present invention, as described above, the vertical tilt angle adjustment of the image sensor 100 provided in the movable unit 60 is performed. In the same way that the tilt angle can be adjusted, the tilt angle of the image sensor 100 in the horizontal direction can be adjusted.

すなわち、図８（ａ）に示す状態において、調整ねじ部２００を締結した場合には、図８（ａ）における向かって左側の部分において、固定部５０と可動部６０とが接近する一方、図８（ａ）において、向かって右側の部分においては、固定部５０と可動部６０とが離間するように、可動部６０が球体部１１０の球の中心を支点として回転する。一方で、図８（ａ）に示す状態において、調整ねじ部２００を緩めた場合には、図８（ａ）における向かって左側の部分において、固定部５０と可動部６０とが離間し、向かって右側の部分においては、弾性部２１１の付勢力によって固定部５０と可動部６０とが接近するように、可動部６０が球体部１１０の球の中心を回転中心として、回転する。よって、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０を用いれば、可動部６０に保持された撮像素子１００の面方向を水平方向にも調整することができる。   That is, in the state shown in FIG. 8A, when the adjustment screw portion 200 is fastened, the fixed portion 50 and the movable portion 60 approach each other at the left side portion in FIG. In 8 (a), in the portion on the right side, the movable part 60 rotates with the center of the sphere of the spherical body part 110 as a fulcrum so that the fixed part 50 and the movable part 60 are separated from each other. On the other hand, when the adjustment screw part 200 is loosened in the state shown in FIG. 8A, the fixed part 50 and the movable part 60 are separated from each other in the left part of FIG. In the right part, the movable part 60 rotates about the center of the sphere of the sphere part 110 so that the fixed part 50 and the movable part 60 approach each other by the urging force of the elastic part 211. Therefore, if the image sensor holding unit 90 of the image sensor driving apparatus 1 according to the embodiment of the present invention is used, the surface direction of the image sensor 100 held by the movable unit 60 can be adjusted also in the horizontal direction.

なお、このとき、例えば、可動部６０に保持された撮像素子１００の水平方向の角度を調整した場合には、垂直調整用の調整ねじ部２００は、固定部５０に対して傾斜することとなる。図９は、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０において、水平方向の調整がなされた場合の、垂直方向調整用の調整ねじ部２００の状態を示す図である。図９（ａ）は、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０において、水平方向の調整がなされる前の状態を示す図であり、図９（ｂ）は、その水平方向の調整がなされた後の、垂直方向のあおりの調整ねじ部２００の状態を示す図である。まず、図９（ａ）に示すように、あおり調整前に、調整ねじ部２００の軸方向と固定部５０の面方向とがなす角度が垂直であるとする。そして、水平方向にあおり調整を行った場合には、図９（ｂ）に示すように、調整ねじ部２００の軸方向が固定部５０の面方向となす角度が変化する。しかしながら、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０によれば、調整ねじ部２００の根元の部分に、球面部２０１が形成されているので、この球面部２０１の中心点Ｐを中心として、調整ねじ部２００の軸方向が回転して、引き続き調整ねじ部２００と固定部５０とを係合させることができる。さらに、調整ねじ部２００と固定部５０の面取り部５２とが接触する部分を結ぶ線上に、球面部２０１の球の中心点Ｐが位置するので、位置ずれ量が少なく、調整ねじ部２００は固定部５０に対して滑らかに回転することができる。   At this time, for example, when the horizontal angle of the image sensor 100 held by the movable portion 60 is adjusted, the adjustment screw portion 200 for vertical adjustment is inclined with respect to the fixed portion 50. . FIG. 9 is a diagram illustrating a state of the adjustment screw portion 200 for vertical adjustment when horizontal adjustment is performed in the image sensor holding unit 90 of the image sensor driving device 1 according to the embodiment of the present invention. . FIG. 9A is a diagram illustrating a state before horizontal adjustment is performed in the image sensor holding unit 90 of the image sensor driving device 1 according to the embodiment of the present invention, and FIG. It is a figure which shows the state of the adjustment screw | thread part 200 of the vertical direction after the adjustment of the horizontal direction was made. First, as shown in FIG. 9A, it is assumed that the angle formed by the axial direction of the adjustment screw portion 200 and the surface direction of the fixing portion 50 is vertical before tilt adjustment. Then, when tilt adjustment is performed in the horizontal direction, as shown in FIG. 9B, the angle formed by the axial direction of the adjustment screw portion 200 and the surface direction of the fixing portion 50 changes. However, according to the image sensor holding unit 90 of the image sensor driving device 1 in the embodiment of the present invention, the spherical surface portion 201 is formed at the base portion of the adjustment screw portion 200. With the point P as the center, the axial direction of the adjusting screw portion 200 rotates, and the adjusting screw portion 200 and the fixing portion 50 can be continuously engaged. Furthermore, since the center point P of the sphere of the spherical surface portion 201 is located on the line connecting the portions where the adjustment screw portion 200 and the chamfered portion 52 of the fixing portion 50 are in contact, the amount of displacement is small and the adjustment screw portion 200 is fixed. It can rotate smoothly with respect to the part 50.

また、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０においては、前述のように、固定部５０の内部に窪部５４を形成して、その内側に球体部１１０が配置されるようにしたので、固定部５０の内部に球体部１１０の球の中心を配置させることが可能となり、この結果、撮像素子１００の水平方向および垂直方向のあおり調整に伴う固定部５０に対する可動部６０の垂直方向および水平方向への位置ずれを少なくすることが可能である。   Further, in the image sensor holding unit 90 of the image sensor driving device 1 according to the embodiment of the present invention, as described above, the recess portion 54 is formed inside the fixed portion 50, and the spherical body portion 110 is arranged inside the recess portion 54. As a result, the center of the sphere 110 can be arranged inside the fixed part 50. As a result, the movable part can be moved relative to the fixed part 50 in accordance with the horizontal and vertical tilt adjustments of the image sensor 100. It is possible to reduce the displacement of the portion 60 in the vertical direction and the horizontal direction.

また、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０によれば、可動部６０と固定部５０とを係合させる球体部１１０の中心位置が、撮像素子１００の撮像面の中心を通る光軸の延長線上に配置されているので、固定部５０に対する可動部６０の回動が、撮像面の中心を通る光軸上を支点として行われるので、撮像素子１００のあおり角度の調整を行うことによる画像のずれの発生を抑制することが可能である。   In addition, according to the image sensor holding unit 90 of the image sensor driving apparatus 1 in the embodiment of the present invention, the center position of the sphere 110 that engages the movable unit 60 and the fixed unit 50 is the image pickup surface of the image sensor 100. Since the rotation of the movable part 60 with respect to the fixed part 50 is performed with the optical axis passing through the center of the imaging surface as a fulcrum, the tilt angle of the image sensor 100 is arranged. It is possible to suppress the occurrence of image shift due to the adjustment.

以上述べたように、本発明の実施の形態における撮像素子駆動装置１を用いれば、可動部６０に設けられた撮像素子１００の撮像面の方向を水平方向および垂直方向にいずれの方向にも変更することができる。すなわち、水平方向および垂直方向のいずれの方向のあおり調整も可能になる。   As described above, when the imaging element driving device 1 according to the embodiment of the present invention is used, the direction of the imaging surface of the imaging element 100 provided in the movable unit 60 is changed to either the horizontal direction or the vertical direction. can do. That is, tilt adjustment in either the horizontal direction or the vertical direction is possible.

なお、本発明の実施の形態における撮像素子駆動装置１の撮像素子保持部９０においては、図６（ａ）に示したように、調整ねじ部２００と固定部５０とが当接する部分を、調整ねじ部２００の調整方向（図６（ａ）においては上下方向）に長穴部５１とした例を示したが、本発明はこの例に限定されるものではない。   In the image sensor holding unit 90 of the image sensor driving device 1 according to the embodiment of the present invention, as shown in FIG. 6A, the portion where the adjustment screw 200 and the fixing unit 50 abut is adjusted. Although an example in which the elongated hole portion 51 is formed in the adjustment direction of the screw portion 200 (vertical direction in FIG. 6A) is shown, the present invention is not limited to this example.

図１０は、本発明の実施の形態における撮像素子保持部の別の例を示す図であり、図１０（ａ）は、あおり調整を行う以前の状態（可動部６０と固定部５０とが互いに平行な状態）を示す図であり、図１０（ｂ）は、調整ねじ部２００を締結して、Ｘ軸方向を中心としてＹ軸方向のあおり調整を行った状態を示す。   FIG. 10 is a diagram illustrating another example of the image sensor holding unit according to the embodiment of the present invention. FIG. 10A illustrates a state before tilt adjustment (the movable unit 60 and the fixed unit 50 are mutually connected). 10 (b) shows a state in which the adjustment screw portion 200 is fastened and the tilt adjustment in the Y-axis direction is performed around the X-axis direction.

図１０に示した撮像素子保持部１９０においては、固定部５０と調整ねじ部２００とが接する部分の両側には、長穴部５１の代わりにＲ面取りされた球面取り部１５１が形成されており、調整ねじ部２００の球面部２０１と球面取り部１５１とが接触しながら、あおり調整を行うことができる。   In the image sensor holding unit 190 shown in FIG. 10, a spherical chamfered portion 151 having a rounded chamfer is formed instead of the long hole portion 51 on both sides of a portion where the fixing portion 50 and the adjusting screw portion 200 are in contact with each other. The tilt adjustment can be performed while the spherical surface portion 201 and the spherical surface removing portion 151 of the adjustment screw portion 200 are in contact with each other.

また、図１０に示した撮像素子保持部１９０においては、保持ねじ部２１０と固定部５０とが接触する側にもＲ面取りされた球面取り部１５１が形成されており、さらに、保持ねじ部２１０にも、弾性部２１１と固定部５０との間に、固定部側が球面形状に加工された球面部材３００が配置されている。   Further, in the image sensor holding unit 190 shown in FIG. 10, a spherical chamfered portion 151 having an R chamfer is also formed on the side where the holding screw portion 210 and the fixing portion 50 are in contact with each other. In addition, a spherical member 300 having a fixed portion processed into a spherical shape is disposed between the elastic portion 211 and the fixed portion 50.

さらに、図１０（ａ）に示したように、本発明の実施の形態における撮像素子保持部１９０は、球面取り部１５１の球の中心（Ｐ１，Ｐ２，Ｐ３およびＰ４）を結ぶ線が、球体部１１０の球の中心（Ｐ５）と略一致するように構成されている。   Further, as shown in FIG. 10A, the image sensor holding unit 190 according to the embodiment of the present invention has a line connecting the sphere centers (P1, P2, P3, and P4) of the spherical portion 151. It is configured to substantially coincide with the center (P5) of the sphere of the portion 110.

このような構成とすることにより、本発明の実施の形態における撮像素子保持部１９０によれば、図１０（ｂ）に示したように、調整ねじ部２００の球面部２０１と固定部５０の球面取り部１５１の少なくとも片側、および、保持ねじ部２１０側に設けられた球面部材３００と固定部５０の球面取り部１５１の少なくとも片側とが接触した状態であおり調整を行うことが可能なので、もっとも滑らかにあおり調整を行うことのできる構成を実現することができる。しかしながら、部品の製造誤差等に鑑みて、実用的には、図６に示したように、調整ねじ部２００と固定部５０とのあおり調整を行う方向（図６においては垂直方向）には、長穴部５１を形成し、保持ねじ部２１０と固定部５０との間は、弾性部２１１で保持する構成とすることができる。   With this configuration, according to the image sensor holding unit 190 in the embodiment of the present invention, as shown in FIG. 10B, the spherical surface portion 201 of the adjustment screw portion 200 and the ball of the fixing portion 50 Since the spherical member 300 provided on at least one side of the chamfered portion 151 and on the holding screw portion 210 side is in contact with at least one side of the spherical chamfered portion 151 of the fixing portion 50 and can be adjusted, it is possible to make the adjustment most smoothly. It is possible to realize a configuration that can perform tilt adjustment. However, in view of manufacturing errors of parts and the like, practically, as shown in FIG. 6, in the direction (in the vertical direction in FIG. 6) in which the adjustment screw portion 200 and the fixing portion 50 are adjusted, The elongated hole portion 51 is formed, and the elastic portion 211 can hold the holding screw portion 210 and the fixing portion 50.

また、本発明の撮像素子駆動装置１に搭載された撮像素子１００から出力される電気信号を画像処理することによって、映像信号を出力するような映像信号処理部を備えた構成とすれば、撮像素子のあおり調整の可能な撮影装置を得ることができる。このような撮影装置においては、調整者が、実際に撮像素子１００で撮影されたピント調整用のテストチャート等の画像を見ながら、画像の全域でピントが合うように、調整ねじ部２００の調整を行うことによって、あおり調整を行うことが可能である。   Further, if the image signal processing unit is configured to output a video signal by performing image processing on an electrical signal output from the image sensor 100 mounted on the image sensor driving device 1 of the present invention, the imaging is performed. An imaging device capable of adjusting the tilt of the element can be obtained. In such a photographing apparatus, the adjuster adjusts the adjustment screw portion 200 so that the image is in focus throughout the entire image while viewing an image such as a test chart for focus adjustment actually photographed by the image sensor 100. It is possible to perform tilt adjustment by performing.

以上述べたように、本発明にかかる撮像素子のあおり調整装置およびそれを用いた撮影装置を用いれば、あおり調整を行った場合に、撮像面の中心と光軸とが大きくずれることがなく、滑らかにあおり角度を調整することが可能という優れた効果を有し、監視カメラ装置、ビデオカメラ装置およびデジタルスチルカメラ装置等の撮像素子を有する撮影装置に関し、特に、撮像素子のあおり角度の調整を行う撮像素子のあおり調整装置およびそれを用いた撮影装置等として有用である。   As described above, when the tilt adjustment device for an image sensor according to the present invention and the photographing device using the same are used, the center of the imaging surface and the optical axis are not greatly shifted when tilt adjustment is performed. The present invention relates to a photographing apparatus having an image pickup device such as a surveillance camera device, a video camera device and a digital still camera device, which has an excellent effect of being able to smoothly adjust the tilt angle, and in particular, adjusting the tilt angle of the image pickup device. It is useful as a tilt adjustment device for an image sensor to be performed and a photographing device using the same.
