特開2015-82072号公報JP 2015-82072A

以下の説明では、互いに直交する3軸をX軸方向、Y軸方向、Z軸方向とする。また、X軸方向の一方側を-X方向、他方側を+X方向とする。Y軸方向の一方側を-Y方向、他方側を+Y方向とする。Z軸方向の一方側を-Z方向(第1方向)、他方側を+Z方向(第2方向)とする。Z軸方向は、撮像モジュール4が備えるレンズ2の光軸Lに沿った光軸方向である。-Z方向は、撮像モジュール4の像側であり、+Z方向は、撮像モジュール4の被写体側である。また、第1軸R1に沿った方向を第1軸R1方向、第2軸R2に沿った方向を第2軸R2方向とする。第1軸R1および第2軸R2は、Z軸回りで、X軸およびY軸に対して45度傾斜する。 In the following description, the three axes orthogonal to each other are defined as the X-axis direction, the Y-axis direction, and the Z-axis direction. Further, one side in the X-axis direction is the −X direction, and the other side is the + X direction. One side in the Y-axis direction is the −Y direction, and the other side is the + Y direction. One side in the Z-axis direction is the −Z direction ( first direction), and the other side is the + Z direction (second direction). The Z-axis direction is the optical axis direction along the optical axis L of the lens 2 included in the image pickup module 4. The −Z direction is the image side of the image pickup module 4, and the + Z direction is the subject side of the image pickup module 4. Further, the direction along the first axis R1 is defined as the first axis R1 direction, and the direction along the second axis R2 is defined as the second axis R2 direction. The first axis R1 and the second axis R2 are tilted 45 degrees with respect to the X axis and the Y axis around the Z axis.

可動体5および回転支持機構6がジンバル機構7により支持された状態では、可動体5の第1側壁21に固定された第1マグネット35と第1コイル115とがX方向で隙間を開けて対向する。第1マグネット35および第1コイル115は、第2振れ補正用磁気駆動機構12を構成する。また、可動体5の第3側壁23に固定された第2マグネット36と第2コイル116とがY方向で隙間を開けて対向する。第2マグネット36および第2コイル116は、第1振れ補正用磁気駆動機構11を構成する。従って、第1コイル115への給電により、可動体5は、Y軸回りに回転する。また、第2コイル116への給電により、可動体5はX軸回りに回転する。振れ補正用磁気駆動機構10は、第1振れ補正用磁気駆動機構11による可動体5のY軸回りの回転と、第2振れ補正用磁気駆動機構12による可動体5のX軸回りの回転と、を合成して、可動体5を第1軸R1回り、および第2軸R2回りに回転させる。 In a state where the movable body 5 and the rotation support mechanism 6 are supported by the gimbal mechanism 7, the first magnet 35 fixed to the first side wall 21 of the movable body 5 and the first coil 115 face each other with a gap in the X direction. do. The first magnet 35 and the first coil 115 constitute a second runout correction magnetic drive mechanism 12. Further, the second magnet 36 fixed to the third side wall 23 of the movable body 5 and the second coil 116 face each other with a gap in the Y direction. The second magnet 36 and the second coil 116 constitute the first magnetic drive mechanism 11 for runout correction. Therefore, the movable body 5 rotates about the Y axis by supplying power to the first coil 115. Further, the movable body 5 rotates about the X axis by supplying power to the second coil 116. The runout correction magnetic drive mechanism 10 includes rotation of the movable body 5 around the Y axis by the first runout correction magnetic drive mechanism 11 and rotation of the movable body 5 around the X axis by the second runout correction magnetic drive mechanism 12. , And rotate the movable body 5 around the first axis R1 and around the second axis R2.

また、可動体5が枠部110の内周側に配置された状態では、可動体5の第4側壁24に固定された第3マグネット37と第3コイル117とがY方向で隙間を開けて対向する。第3マグネット37および第3コイル117は、ローリング補正用磁気駆動機構13を構成する。従って、第3コイル117への給電により、可動体5は、光軸L回りに回転する。 Further, in a state where the movable body 5 is arranged on the inner peripheral side of the frame portion 110, a gap is opened between the third magnet 37 and the third coil 117 fixed to the fourth side wall 24 of the movable body 5 in the Y direction. opposite. The third magnet 37 and the third coil 117 constitute a rolling correction magnetic drive mechanism 13. Therefore, the movable body 5 rotates around the optical axis L by supplying power to the third coil 117 .

なお、図2、図6に示すように、第1コイル115の外周側には、矩形の第1磁性板141が配置されている。第2コイル116の外周側には、矩形の第2磁性板142が配置されている。第1磁性板141は、可動体5の第1マグネット35と対向しており、可動体5をY軸回りの回転方向における基準回転位置に復帰させるための磁気バネを構成している。第2磁性板142は、可動体5の第2マグネット36と対向しており、可動体5をX軸回りの回転方向における基準回転位置に復帰させるための磁気バネを構成している。また、図1、図6に示すように、第3コイル117の外周側には、矩形の第3磁性板143が配置されている。第3磁性板143は、可動体5の第3マグネット37と対向しており、可動体5を、光軸L回りの回転方向における基準回転位置に復帰させるための磁気バネを構成している。 As shown in FIGS. 2 and 6, a rectangular first magnetic plate 141 is arranged on the outer peripheral side of the first coil 115. A rectangular second magnetic plate 142 is arranged on the outer peripheral side of the second coil 116. The first magnetic plate 141 faces the first magnet 35 of the movable body 5, and constitutes a magnetic spring for returning the movable body 5 to a reference rotation position in the rotation direction around the Y axis. The second magnetic plate 142 faces the second magnet 36 of the movable body 5, and constitutes a magnetic spring for returning the movable body 5 to a reference rotation position in the rotation direction around the X axis. Further, as shown in FIGS. 1 and 6, a rectangular third magnetic plate 143 is arranged on the outer peripheral side of the third coil 117. The third magnetic plate 143 faces the third magnet 37 of the movable body 5, and constitutes a magnetic spring for returning the movable body 5 to a reference rotation position in the rotation direction around the optical axis L.
