CROSS REFERENCE TO RELATED APPLICATION 
     The present application claims priority under 35 U.S.C. § 119 to Japanese Application No. 2019-110954 filed on Jun. 14, 2019, and the entire content of which is incorporated herein by reference. 
     TECHNICAL FIELD 
     The present invention relates to an optical unit with a shake correction function structured to perform a shake correction by turning an imaging module around predetermined three axes. 
     BACKGROUND 
     In an optical unit which is mounted on a portable terminal or a movement body, in order to restrain disturbance of a photographed image of the portable terminal or when the movement body is moved, an optical unit has been known in which a movable body on which an optical module is mounted is turnable around an optical axis, around a first axis perpendicular to the optical axis, and around a second axis perpendicular to the optical axis and the first axis. Such an optical unit with a shake correction function is disclosed in Japanese Patent Laid-Open No. 2015-82072 (Patent Literature 1). 
     An optical unit with a shake correction function described in Patent Literature 1 includes a movable body, a fixed body and a turning support mechanism structured to turnably support the movable body around a predetermined axial line with respect to the fixed body. The movable body includes an optical module having a lens, a support body which surrounds the optical module, and a gimbal mechanism structured to turnably support the optical module around a first axis and around a second axis on an inner side of the support body. Further, the optical unit with a shake correction function includes a turning magnetic drive mechanism structured to turn the optical module around the first axis and around the second axis in the movable body, and a rolling magnetic drive mechanism structured to turn the movable body around a predetermined axial line and thereby to turn the optical module around an optical axis. 
     In the optical unit with a shake correction function described in Patent Literature 1, when the optical module is not turned around the first axis or around the second axis, a predetermined axial line (turning axis of the movable body) around which the movable body is turned by the turning support mechanism and an optical axis are coincided with each other. However, when the optical module is turned around the first axis or around the second axis, the turning axis of the movable body by the turning support mechanism is deviated from the optical axis of the optical module on the movable body. Therefore, when the optical module is turned around the first axis or around the second axis, if the rolling magnetic drive mechanism is driven to turn the movable body, a problem occurs that the optical module is not turned around the optical axis. 
     SUMMARY 
     In view of the problem described above, the present invention provides an optical unit with a shake correction function in which the turning axis of the movable body and the optical axis are capable of being coincided with each other. 
     To solve the above-mentioned problem, the present invention provides an optical unit with a shake correction function including a movable body having a lens, a turning support mechanism structured to turnably support the movable body around an optical axis of the lens, a gimbal mechanism structured to turnably support the turning support mechanism around a first axis intersecting the optical axis and turnably support the turning support mechanism around a second axis intersecting the optical axis and the first axis, a fixed body which supports the movable body through the gimbal mechanism and the turning support mechanism, a shake correction magnetic drive mechanism structured to turn the movable body around the first axis and around the second axis, and a rolling correction magnetic drive mechanism structured to turn the movable body around the optical axis. The turning support mechanism includes a plate roll which is fixed to the movable body, a plate holder provided with a facing part which faces the plate roll in a direction of the optical axis, and a turning mechanism which is provided between the plate roll and the facing part and is structured so that the plate roll is turnable with respect to the plate holder around the optical axis. The gimbal mechanism includes a gimbal frame and a first connection mechanism which turnably connects the plate holder with the gimbal frame around the first axis, and the first connection mechanism includes a first support member which is protruded from the gimbal frame to a side of the plate holder on the first axis, and a first concave curved face which is provided in the plate holder and is turnably brought into contact with a tip end of the first support member. A reinforcement member is fixed to the gimbal frame so that a portion of the gimbal frame where the first axis is passed is reinforced.

     DETAILED DESCRIPTION 
     According to the present invention, the turning support mechanism which turnably supports the movable body around the optical axis is turnably supported around the first axis and around the second axis intersecting the optical axis by the gimbal mechanism. Therefore, the turning support mechanism is capable of turning around the first axis and around the second axis together with the movable body. Therefore, even when the movable body is turned around the first axis or around the second axis, the turning axis of the movable body by the turning support mechanism and the optical axis of the movable body are coincided with each other. Therefore, in a case that the movable body is turning around the first axis or around the second axis, when the rolling correction magnetic drive mechanism is driven to turn the movable body, the movable body is turned around the optical axis. 
     In the present invention, the turning support mechanism which supports the movable body is supported by the gimbal frame through the first connection mechanism. Therefore, in comparison with a case that the gimbal frame supports only the movable body through the first connection mechanism, a large load is applied to a portion of the gimbal frame structuring the first connection mechanism, in other words, a large load is applied to a portion and its periphery of the gimbal frame where the first axis is passed. In this case, when the gimbal frame is deformed due to a load from the first connection mechanism, a situation may be occurred that the first support member and the first concave curved face of the plate holder are separated from each other and the plate holder is unable to be turnably supported by the gimbal frame. In order to prevent such a problem, according to the present invention, the gimbal frame is fixed with the reinforcement member for reinforcing a portion of the gimbal frame where the first axis is passed. As a result, deformation of the gimbal frame can be prevented or suppressed and thus, a situation can be avoided that the plate holder is unable to be turnably supported by the gimbal frame. 
     In the present invention, it may be structured that, when one side in a direction of the optical axis is defined as a first direction and the other side in the direction of the optical axis is defined as a second direction, the gimbal frame includes a gimbal frame main body part which is located in the second direction with respect to the plate holder, and a pair of first gimbal frame extended parts which are protruded from the gimbal frame main body part to both sides in a direction of the first axis and are extended in the first direction. The pair of the first gimbal frame extended parts is located on an outer peripheral side with respect to the movable body. Each of the pair of the first gimbal frame extended parts is provided with a first extended portion of the first gimbal frame extended part which is extended in a direction separated from the gimbal frame main body part in the direction of the first axis, a second extended portion of the first gimbal frame extended part which is inclined in the first direction from a tip end of the first extended portion of the first gimbal frame extended part toward a direction separated from the gimbal frame main body part, and a third extended portion of the first gimbal frame extended part which is extended in the first direction from an end in the first direction of the second extended portion of the first gimbal frame extended part on the outer peripheral side with respect to the plate holder. The first support member is protruded to a side of the movable body from the third extended portion of the first gimbal frame extended part, and the reinforcement member is fixed to each of the first gimbal frame extended parts. The reinforcement member is provided with a first reinforcement portion which is located in the second direction with respect to the first extended portion of the first gimbal frame extended part, a second reinforcement portion which is extended from an end on the outer peripheral side of the first reinforcement portion along the second extended portion of the first gimbal frame extended part, and a third reinforcement portion which is extended along the third extended portion of the first gimbal frame extended part from an end in the first direction of the second extended portion of the first gimbal frame extended part. According to this structure, each of a pair of the first gimbal frame extended parts can be prevented or suppressed by the reinforcement member from deforming in a direction separated from each other. 
     In the present invention, it may be structured that a thickness of the reinforcement member is thicker than a thickness of the first gimbal frame extended part in a laminated direction in a state that the first gimbal frame extended part and the reinforcement member are overlapped with each other. According to this structure, the reinforcement member is easily structured of a member whose rigidity is higher than that of the first gimbal frame extended part. 
     In the present invention, it may be structured that the third extended portion of the first gimbal frame extended part is provided with a gimbal frame extended part through-hole which penetrates through the third extended portion in a direction of the first axis, and a support member fixing tube part which is protruded to an opposite side to the movable body in the direction of the first axis from an opening edge of the gimbal frame extended part through-hole provided in the third extended portion of the first gimbal frame extended part. The third reinforcement portion is provided with a reinforcement member through-hole which penetrates through the third reinforcement portion in the direction of the first axis and is communicated with the gimbal frame extended part through-hole, and the support member fixing tube part is inserted into the reinforcement member through-hole, and the first support member is held by the support member fixing tube part and is protruded from the third extended portion of the first gimbal frame extended part. According to this structure, the first support member is held by the first gimbal frame extended part and the reinforcement member. Further, the first support member is inserted into the support member fixing tube part which is extended in the first axis direction and thus, the first support member can be moved in the first axis direction along the support member fixing tube part. As a result, a protruding amount of the first support member which is protruded from the first gimbal frame extended part to a side of the movable body can be adjusted. In this case, when a protruding amount of the first support member can be adjusted, a contact pressure of the first support member with the first concave curved face can be adjusted. Further, when a protruding amount of the first support member can be adjusted, a situation is easily avoided that the first support member and the first concave curved face are separated from each other and the plate holder is unable to be turnably supported by the gimbal frame. 
     In the present invention, it may be structured that the first support member is fixed to the third extended portion of the first gimbal frame extended part. 
     In the present invention, it may be structured that the third extended portion of the first gimbal frame extended part is provided with a gimbal frame extended part through-hole which penetrates through the third extended portion in the direction of the first axis, the third reinforcement portion is provided with a reinforcement member through-hole which penetrates through the third reinforcement portion in the direction of the first axis and is communicated with the gimbal frame extended part through-hole, the first support member is inserted into the reinforcement member through-hole and is fixed to the reinforcement member, and the first support member penetrates through the gimbal frame extended part through-hole and protrudes from the third extended portion of the first gimbal frame extended part to a side of the movable body. According to this structure, the first support member is held by the reinforcement member through-hole penetrating in the first axial direction and thus, the first support member can be moved in the first axis direction along the reinforcement member through-hole. As a result, a protruding amount of the first support member which is protruded from the gimbal frame extended part to a side of the movable body can be adjusted. In this case, when a protruding amount of the first support member can be adjusted, a contact pressure of the first support member with the first concave curved face can be adjusted. Further, when a protruding amount of the first support member can be adjusted, a situation is easily avoided that the first support member and the first concave curved face are separated from each other and the plate holder is unable to be turnably supported by the gimbal frame.

According to this structure, the first support member is held by the gimbal frame extended part through-hole and the reinforcement member through-hole penetrating in the first axial direction and thus, the first support member can be moved in the first axis direction along the gimbal frame extended part through-hole and the reinforcement member through-hole. As a result, a protruding amount of the first support member which is protruded from the gimbal frame extended part to a side of the movable body can be adjusted. In this case, when a protruding amount of the first support member can be adjusted, a contact pressure of the first support member with the first concave curved face can be adjusted. Further, when a protruding amount of the first support member can be adjusted, a situation is easily avoided that the first support member and the first concave curved face are separated from each other and the plate holder is unable to be turnably supported by the gimbal frame. 
     In the present invention, it may be structured that the reinforcement member is provided with an adhesive injection hole, which penetrates through the first reinforcement portion in the direction of the optical axis, and a communication groove which is extended along the first reinforcement portion, the second reinforcement portion and the third reinforcement portion on a surface of a side of the first gimbal frame extended part and is communicated with the adhesive injection hole. According to this structure, when an adhesive is injected into the adhesive injection hole after the reinforcement member is abutted with the first gimbal frame extended part, the adhesive is introduced into the communication groove. Therefore, the reinforcement member is easily fixed to the first gimbal frame extended part. 
     In the present invention, it may be structured that the reinforcement member is provided with a pair of first reinforcement member protruded parts which are protruded toward a side of the movable body on both sides of the first gimbal frame extended part in a circumferential direction around the optical axis, and a second reinforcement member protruded part which is protruded toward the side of the movable body in the first direction of the first gimbal frame extended part. The first gimbal frame extended part is provided with a pair of protruded parts of the first gimbal frame extended part protruded to both sides in the circumferential direction in the first direction with respect to the pair of the first reinforcement member protruded parts and, when viewed in the direction of the optical axis, the second reinforcement member protruded part and the third extended portion of the first gimbal frame extended part are overlapped with each other, and the pair of the first reinforcement member protruded parts and the pair of the protruded parts of the first gimbal frame extended part are overlapped with each other.

Further, the reinforcement member can be prevented from coming out from the first gimbal frame extended part in the second direction by the second reinforcement member protruded part. 
     In the present invention, it may be structured that the gimbal mechanism includes a second connection mechanism which turnably connects the gimbal frame with the fixed body around the second axis, the gimbal frame is provided with a pair of second gimbal frame extended parts which are protruded from the gimbal frame main body part to both sides in a direction of the second axis and are extended in the first direction, the pair of the second gimbal frame extended parts is located on an outer peripheral side with respect to the movable body, and the fixed body includes a frame part which surrounds the movable body, the plate holder and the gimbal frame from an outer peripheral side. The second connection mechanism includes a second support member which is protruded to a side of the gimbal frame on the second axis from each of diagonal portions of the frame part in a direction of the second axis, and a second concave curved face which is provided in each of the pair of the second gimbal frame extended parts and is brought into contact with a tip end of the second support member. According to this structure, the turning support mechanism can be turnably supported by the gimbal mechanism around the second axis. 
     In the present invention, it may be structured that an inner peripheral face of the frame part is provided with a moving range restriction part which faces the reinforcement member through a first space in a circumferential direction and is abutted with the reinforcement member when the gimbal frame is displaced in the circumferential direction to restrict a moving range of the gimbal frame, and a turning range restriction part which faces the reinforcement member through a second space in a direction of the first axis and is abutted with the reinforcement member when the gimbal frame is turned around the second axis to restrict a turning range of the gimbal frame.

Therefore, deformation and damage of the gimbal frame can be prevented or suppressed. 
     According to the present invention, the turning support mechanism which turnably supports the movable body around the optical axis is turnably supported by the gimbal mechanism around the first axis and around the second axis intersecting the optical axis. Therefore, the turning support mechanism is capable of turning around the first axis and around the second axis together with the movable body. Therefore, even when the movable body is turned around the first axis or around the second axis, the turning axis of the movable body by the turning support mechanism and the optical axis of the movable body are coincided with each other. Further, the gimbal frame of the gimbal mechanism is fixed with the reinforcement member which reinforces a portion of the gimbal frame to which the first support member for connecting the gimbal frame with the turning support mechanism is attached. Therefore, a situation can be avoided that the gimbal frame is deformed to be unable to turnably support the turning support mechanism.

     An optical unit  1  with a shake correction function includes an imaging module  4  having a lens  2  and an imaging element  3 . The optical unit  1  with a shake correction function is, for example, used in an optical device such as a cell phone with a camera and a drive recorder or in an optical device such as an action camera mounted on a movement body such as a helmet, a bicycle, a radio-controlled helicopter or a wearable camera. In the optical device, when a shake is occurred in the optical device at the time of photographing, a disturbance is generated in a photographed image. In order to avoid a photographed image being inclined, the optical unit  1  with a shake correction function corrects an inclination of a movable body based on acceleration, angular velocity, shaking amount and the like detected by a detection means such as a gyroscope. 
     An optical unit  1  with a shake correction function in this embodiment performs a shake correction by turning the imaging module  4  around an optical axis “L”, around a first axis “R 1 ” perpendicular to the optical axis “L”, and around a second axis “R 2 ” perpendicular to the optical axis “L” and the first axis “R 1 ”. Therefore, the optical unit  1  with a shake correction function performs a rolling correction, a pitching correction and a yawing correction.

One side in the “Z”-axis direction is referred to as a “−Z” direction (first direction), and the other side is referred to as a “+Z” direction (second direction). The “Z”-axis direction is an optical axis direction along the optical axis “L” of the lens  2  provided in the imaging module  4 . The “−Z” direction is on an image side with respect to the imaging module  4 , and the “+Z” direction is on an object side with respect to the imaging module  4 . Further, a direction along the first axis “R 1 ” is referred to as a first axis “R 1 ” direction, and a direction along the second axis “R 2 ” is referred to as a second axis “R 2 ” direction.

An outer peripheral side portion of the plate spring  70  is abutted with the plate holder ring-shaped part  56  from the “−Z” direction side in a state that the outer peripheral side portion is resiliently bent in the “−Z” direction. More specifically, the plate holder ring-shaped part  56  is provided with a thin thickness portion  56   a  which is recessed in the “+Z” direction in an end edge portion on the inner peripheral side. An outer peripheral side portion of the plate spring  70  is abutted with the thin thickness portion  56   a  from a side in the “−Z” direction in a state that the outer peripheral side portion is elastically deformed in a direction separated from the plate roll ring-shaped part  47 . Therefore, the plate spring  70  urges the plate holder  42  (plate holder ring-shaped part  56 ) toward the plate roll  41  (plate roll ring-shaped part  47 ) by its own elastic restoration force. 
     In this embodiment, as shown in  FIG. 9 , the movable body  5  is provided with a plate roll fixing hole  72 , into which the fixing part  53  of each of a pair of the plate roll extended parts  48  is inserted, on each of both end portions in the second axis “R 2 ” direction of the movable body main body part  17 .

When the fixing part  53  is to be inserted into the plate roll fixing hole  72 , the movable body protruded part  18  is inserted into a center hole of the plate roll ring-shaped plate  50 , and the movable body protruded part  18  is fitted to the bent portion  51 . As a result, the plate roll  41  is coaxially positioned with the movable body protruded part  18 . In other words, the plate roll  41  is positioned with the optical axis “L” as a reference. Further, when the fixing part  53  of each of the plate roll extended parts  48  is press-fitted to each of the plate roll fixing holes  72 , the protruded parts  53   a  and the protruded part  53   b  of the fixing part  53  are plastically deformed to be in a crushed state. As a result, the plate roll  41  and the movable body  5  are fixed to each other. When the plate roll  41  and the movable body  5  are fixed to each other, the movable body  5  is integrally turnable with the plate roll  41  around the optical axis “L”.

As shown in  FIG. 12 , the groove part  120  is defined by a bottom face  120   a  extended in the “Z”-axis direction and a pair of side faces  120   b  which are extended to the inner peripheral side from both ends in the circumferential direction around the optical axis “L” of the bottom face  120   a.    
     As shown in  FIGS. 5 and 12 , each of diagonal portions of the frame part  110  in the second axis “R 2 ” direction is fixed with a second support member  82  which is protruded to a side of the gimbal frame  75  on the second axis “R 2 ”. The second support member  82  is a spherical body. More specifically, as shown in  FIG. 13 , each of the diagonal portions in the second axis “R 2 ” direction of the frame part  110  is provided with a recessed part  121  which is recessed to an outer side in the radial direction. Each of the recessed parts  121  is defined by a bottom face  121   a  extended in the second axis “R 2 ” direction, a rear face  121   b  which is extended in the “+Z” direction from an outer peripheral end of the bottom face  121   a , and a pair of side faces  121   c  which are extended in the “+Z” direction from both ends in the circumferential direction around the optical axis “L” of the bottom face  121   a . The bottom face  121   a  is provided with a first groove  121   d  extended in the second axis “R 2 ” direction with a constant width in its center portion in the circumferential direction. The rear face  121   b  is provided with a second groove  121   e  extended in the “Z”-axis direction with a constant width in its center portion in the circumferential direction. The first groove  121   d  and the second groove  121   e  are communicated with each other. 
     As shown in  FIG. 12 , the gimbal frame receiving member  125  is fixed to each of the recessed parts  121 . As shown in  FIG. 13 , the gimbal frame receiving member  125  includes the second support member  82  and a thrust receiving member  126  to which the second support member  82  is fixed. The thrust receiving member  126  and the second support member  82  are made of metal. As shown in  FIGS. 7 and 13 , the thrust receiving member  126  is provided with a first plate part  131  in a plate shape extended in the “Z”-axis direction, a second plate part  132  which is bent at a substantially right angle from an end part in the “−Z” direction of the first plate part  131  and is extended to an inner side in the radial direction, and a pair of third plate parts  133  which are bent at a substantially right angle from both sides in the circumferential direction in an end part in the “+Z” direction of the first plate part  131  and are extended to an inner side in the radial direction. End parts on the inner peripheral side of a pair of the third plate parts  133  are bent in directions separated from each other in the circumferential direction. A second support member fixing hole  131   a  is provided in the first plate part  131 . The second support member fixing hole  131   a  is located between the second plate part  132  and a pair of the third plate parts  133  in the “Z”-axis direction. The second support member  82  is fixed to the first plate part  131  by welding in a state that a part on the outer peripheral side of the second support member  82  is partly fitted to the second support member fixing hole  131   a . The second support member  82  is protruded to the inner peripheral side from the first plate part  131 . 
     When the gimbal frame receiving member  125  is to be inserted to the recessed part  121  of the case  109 , as shown in  FIG. 12 , a pair of the third plate parts  133  of the thrust receiving member  126  is abutted with a pair of the side faces  121   c  of the recessed part  121 . As a result, the second support member  82  is positioned in the circumferential direction around the optical axis “L”. Further, the second plate part  132  of the thrust receiving member  126  is abutted with the bottom face  121   a  of the recessed part  121 . As a result, the second support member  82  is positioned in the “Z”-axis (optical axis “L”) direction. The thrust receiving member  126  is fixed to the recessed part  121  by an adhesive applied to the first groove  121   d  and the second groove  121   e . When the thrust receiving member  126  is fixed to the recessed part  121 , the second support member  82  is located on the second axis “R 2 ” line and is protruded to the inner peripheral side from the first plate part  131  of the thrust receiving member  126  which is fixed to the frame part  110 . 
     Second Connection Mechanism 
     When the movable body  5  is to be turnably supported around the second axis “R 2 ” line by the gimbal mechanism  7 , the gimbal frame  75  by which the movable body  5  and the turning support mechanism  6  are supported is disposed on an inner side of the frame part  110 . Further, as shown in  FIG. 4 , the first gimbal frame extended parts  86  and the reinforcement members  100  are inserted to the groove parts  120  provided in the diagonal portions of the frame part  110 . In addition, as shown in  FIG. 5 , the second support member  82  (spherical body) disposed in the diagonal portion of the frame part  110  and the third extended portion  87   c  of the second gimbal frame extended part  87  having the second concave curved face  83  are faced each other. In addition, a tip end portion of the second support member  82  is inserted to the second concave curved face  83  and is brought into contact with the second concave curved face  83 . Further, as shown in  FIG. 7 , a pair of the protruded parts  95  of the second gimbal frame extended part  87  is inserted between a pair of the third plate parts  133  and the second plate part  132  of the thrust receiving member  126 . In this manner, the second connection mechanism  77  is structured and thus, the turning support mechanism  6  is turnably supported by the gimbal mechanism  7  around the second axis “R 2 ”. In other words, the turning support mechanism  6  is turnably supported around the first axis “R 1 ” and is turnably supported around the second axis “R 2 ” by the gimbal mechanism  7 . Therefore, the movable body  5  supported by the turning support mechanism  6  is also turnably supported around the first axis “R 1 ” and is also turnably supported around the second axis “R 2 ” by the gimbal mechanism  7 . 
     In this embodiment, the gimbal frame  75  is a plate spring and thus, the second gimbal frame extended part  87  is elastically deformable in the second axis “R 2 ” direction. Therefore, when the second support member  82  and the second concave curved face  83  of the second gimbal frame extended part  87  are to be brought into contact with each other, the second gimbal frame extended part  87  is resiliently bent to the inner peripheral side and is brought into contact with the second support member  82 . As a result, the second gimbal frame extended part  87  is elastically brought into contact with the second support member  82  from the inner peripheral side by an elastic restoration force toward the outer peripheral side. Therefore, release of connection between the second gimbal frame extended part  87  and the frame part  110  can be prevented or suppressed. 
     Shake Correction Magnetic Drive Mechanism and Rolling Correction Magnetic Drive Mechanism 
     In a state that the movable body  5  and the turning 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 through a gap space in the “X” direction. The first magnet  35  and the first coil  115  structure the second shake 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 through a gap space in the “Y” direction. The second magnet  36  and the second coil  116  structure the first shake correction magnetic drive mechanism  11 . Therefore, the movable body  5  is turned around the “Y”-axis by supplying power to the first coil  115 . Further, the movable body  5  is turned around the “X”-axis by supplying power to the second coil  116 . The shake correction magnetic drive mechanism  10  combines turning around the “Y”-axis of the movable body  5  by the first shake correction magnetic drive mechanism  11  and turning around the “X”-axis of the movable body  5  by the second shake correction magnetic drive mechanism  12  to turn the movable body  5  around the first axis “R 1 ” and around the second axis “R 2 ”. 
     Further, in a state that the movable body  5  is disposed on the inner peripheral side with respect to the frame part  110 , the third magnet  37  fixed to the fourth side wall  24  of the movable body  5  and the third coil  117  face each other through a gap space in the “Y” direction. The third magnet  37  and the third coil  117  structure the rolling correction magnetic drive mechanism  13 . Therefore, the movable body  5  is turned around the optical axis “L” by supplying power to the third coil  117 . 
     In this embodiment, as shown in  FIGS. 4 and 5 , a gap space “D 1 ” in the “Z”-axis direction between the second gimbal frame extended part  87  and the plate roll extended part  48  is larger than a gap space “D 2 ” in the “Z”-axis direction between the first gimbal frame extended part  86  and the plate holder extended part  57 . Therefore, when the turning support mechanism  6  is turned around the first axis “R 1 ” by the gimbal mechanism  7 , the turning support mechanism  6  is restrained from being brought into contact with the second gimbal frame extended part  87 . 
     Further, in a state that the gimbal frame  75  is connected with the frame part  110  through the second connection mechanism  77 , a pair of the first gimbal frame extended parts  86  of the gimbal frame  75  and the reinforcement members  100  are disposed on inner sides of the groove parts  120  provided in the diagonal portions in the first axis “R 1 ” direction of the frame part  110 . In this embodiment, as shown in  FIG. 3 , each of a pair of the side faces  120   b  of the groove part  120  faces the reinforcement member  100  with a first predetermined space interposed therebetween in the circumferential direction around the optical axis “L”. A pair of the side faces  120   b  of the groove part  120  functions as a moving range restriction part  145  which is capable of abutting with the reinforcement member  100  when the gimbal frame  75  is displaced in the circumferential direction to restrict a moving range of the gimbal frame  75 . Further, as shown in  FIGS. 3 and 4 , the bottom face  120   a  of the groove part  120  which is located on an outer side in the radial direction with respect to the reinforcement member  100  faces the reinforcement member  100  through a second space in the first axis “R 1 ” direction. The bottom face  120   a  of the groove part  120  functions as a turning range restriction part  146  which is capable of abutting with the reinforcement member  100  when the gimbal frame  75  is turned around the second axis “R 2 ” to restrict a turning range of the gimbal frame  75 . 
     In this embodiment, as shown in  FIGS. 2 and 6 , a first magnetic plate  141  in a rectangular shape is disposed on the outer peripheral side of the first coil  115 . A second magnetic plate  142  in a rectangular shape is disposed 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 structures a magnetic spring for returning the movable body  5  to a turning reference position in a turning direction around the “Y”-axis. The second magnetic plate  142  faces the second magnet  36  of the movable body  5  and structures a magnetic spring for returning the movable body  5  to a turning reference position in a turning direction around the “X”-axis. Further, as shown in  FIGS. 1 and 6 , a third magnetic plate  143  in a rectangular shape is disposed 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 structures a magnetic spring for returning the movable body  5  to a turning reference position in a turning direction around the optical axis “L”. 
     Operations and Effects 
     According to this embodiment, the turning support mechanism  6  which turnably supports the movable body  5  around the optical axis “L” is turnably supported by the gimbal mechanism  7  around the first axis “R 1 ” and around the second axis “R 2 ” intersecting the optical axis “L”. Therefore, the turning support mechanism  6  is capable of turning around the first axis “R 1 ” and around the second axis “R 2 ” together with the movable body  5 . Therefore, even when the movable body  5  is turned around the first axis “R 1 ” or around the second axis “R 2 ”, the turning axis of the movable body  5  by the turning support mechanism  6  and the optical axis “L” of the movable body  5  are coincided with each other. Accordingly, in a case that the movable body  5  is turning around the first axis “R 1 ” or around the second axis “R 2 ”, when the rolling correction magnetic drive mechanism  13  is driven to turn the movable body  5 , the movable body  5  is turned around the optical axis “L”. 
     In this embodiment, the turning support mechanism  6  which supports the movable body  5  is supported by the gimbal frame  75  through the first connection mechanism  76 . Therefore, in comparison with a structure that the gimbal frame  75  supports only the movable body  5  through the first connection mechanism  76 , a large load is applied to a portion of the gimbal frame  75  structuring the first connection mechanism  76  (portion of the gimbal frame where the first axis “R 1 ” is passed and its periphery). Further, when the gimbal frame  75  is deformed due to a load from the first connection mechanism  76 , there may be occurred that the first support member  81  and the first concave curved face  61  of the plate holder  42  are separated from each other and the plate holder  42  is unable to be turnably supported by the gimbal frame  75 . In order to prevent such a problem, the gimbal frame  75  is fixed with the reinforcement member  100  for reinforcing a portion of the gimbal frame  75  where the first axis “R 1 ” is passed. Therefore, deformation of the gimbal frame  75  can be prevented or suppressed. Accordingly, a situation can be avoided that the plate holder  42  is unable to be turnably supported by the gimbal frame  75 . 
     Further, in this embodiment, the gimbal frame  75  is provided with the gimbal frame main body part  85  located in the “+Z” direction of the turning support mechanism  6  and a pair of the first gimbal frame extended parts  86  which are protruded from the frame main body part  85  to both sides in the first axis “R 1 ” direction and are extended in the “−Z” direction. A pair of the first gimbal frame extended parts  86  is located on the outer peripheral side with respect to the movable body  5 . Further, each of a pair of the first gimbal frame extended parts  86  is provided with the first extended portion  86   a  of the first gimbal frame extended part  86  which is extended in a direction separated from the frame main body part in the first axis “R 1 ” direction, the second extended portion  86   b  of the first gimbal frame extended part  86  which is inclined in a direction separated from the frame main body part toward the “−Z” direction from a tip end of the first extended portion  86   a  of the first gimbal frame extended part  86 , and the third extended portion  86   c  of the first gimbal frame extended part  86  which is extended from an end in the “−Z” direction of the second extended portion  86   b  of the first gimbal frame extended part  86  in the “−Z” direction on the outer peripheral side with respect to the turning support mechanism  6 . The first support member  81  is protruded to a side of the movable body  5  from the third extended portion  86   c  of the first gimbal frame extended part  86 . On the other hand, the reinforcement member  100  is fixed to each of the first gimbal frame extended parts  86 . The reinforcement member  100  is provided with the first reinforcement portion  100   a , which is located in the “+Z” direction of the first extended portion  86   a  of the first gimbal frame extended part  86 , the second reinforcement portion  100   b  which is extended along the second extended portion  86   b  of the first gimbal frame extended part  86  from an end on the outer peripheral side of the first reinforcement portion  100   a , and the third reinforcement portion  100   c  which is extended along the third extended portion  86   c  of the first gimbal frame extended part  86  from an end in the “−Z” direction of the second extended portion  86   b  of the first gimbal frame extended part  86 . Therefore, each of a pair of the first gimbal frame extended parts  86  can be prevented or suppressed from deforming in a direction separated from each other by the reinforcement member  100 . 
     In addition, in this embodiment, a thickness of the reinforcement member  100  in a laminated direction formed by overlapping the first gimbal frame extended part  86  with the reinforcement member  100  is thicker than that of the first gimbal frame extended part  86 . Therefore, the reinforcement member  100  is easily structured of a member whose rigidity is higher than that of the first gimbal frame extended part  86 . 
     Further, in this embodiment, the third extended portion  86   c  of the first gimbal frame extended part  86  is provided with the gimbal frame extended part through-hole  92  penetrating in the first axis “R 1 ” direction and the support member fixing tube part  93  which is protruded from an opening edge of the gimbal frame extended part through-hole  92  in the third extended portion  86   c  of the first gimbal frame extended part  86  to an opposite side to the movable body  5 . On the other hand, the third reinforcement portion  100   c  of the reinforcement member  100  is provided with the reinforcement member through-hole  103  which is penetrated in the first axis “R 1 ” direction to be communicated with the gimbal frame extended part through-hole  92  and into which the support member fixing tube part  93  is inserted. The first support member  81  is held by the support member fixing tube part  93  and is protruded from the third extended portion  86   c  of the first gimbal frame extended part  86 . Therefore, the first support member  81  is held by the first gimbal frame extended part  86  and the reinforcement member  100 . Further, the first support member  81  is inserted into the support member fixing tube part  93  which is extended in the first axis “R 1 ” direction and thus, the first support member  81  can be moved in the first axis “R 1 ” direction along the support member fixing tube part  93 . Therefore, a protruding amount of the first support member  81  protruded from the first gimbal frame extended part  86  to a side of the movable body  5  can be adjusted. When a protruding amount of the first support member  81  can be adjusted, a situation is easily avoided that the first support member  81  and the first concave curved face  61  of the plate holder  42  are separated from each other and the plate holder  42  is unable to be turnably supported by the gimbal frame  75 . 
     In addition, in this embodiment, the reinforcement member  100  is provided with the adhesive injection hole  101 , which is penetrated through the first reinforcement portion  100   a  in the “Z”-axis direction, and the communication groove  102  which is extended on a face on the first gimbal frame extended part  86  side along the first reinforcement portion  100   a , the second reinforcement portion  100   b  and the third reinforcement portion  100   c  to be communicated with the adhesive injection hole  101 . Therefore, when an adhesive is injected through the adhesive injection hole  101  in a state that the reinforcement member  100  and the first gimbal frame extended part  86  are brought into contact with each other, the adhesive is introduced into the communication groove  102 . Further, the reinforcement member  100  and the first gimbal frame extended part  86  are fixed to each other by the adhesive which is introduced into the communication groove  102 . Therefore, the reinforcement member  100  is easily fixed to the first gimbal frame extended part  86 . 
     Further, in this embodiment, the reinforcement member  100  is provided with a pair of the first reinforcement member protruded parts  104 , which are protruded toward a side of the movable body  5  on both sides of the first gimbal frame extended part  86  in the circumferential direction around the optical axis “L”, and the second reinforcement member protruded part  105  which is protruded toward the movable body  5  side in the “−Z” direction with respect to the first gimbal frame extended part  86 . On the other hand, the first gimbal frame extended part  86  is provided with a pair of the protruded parts  94  of the first gimbal frame extended part  86  which are protruded to both sides in the circumferential direction in the “−Z” direction with respect to a pair of the first reinforcement member protruded parts  104 . Further, when viewed in the “Z”-axis direction, the second reinforcement member protruded part  105  and the third extended portion  86   c  of the first gimbal frame extended part  86  are overlapped with each other, and a pair of the first reinforcement member protruded parts  104  and a pair of the protruded parts  94  of the first gimbal frame extended part  86  are overlapped with each other. Therefore, the first gimbal frame extended part  86  can be prevented from disengaging from the reinforcement member  100  in the “+Z” direction by a pair of the first reinforcement member protruded parts  104  and a pair of the protruded parts  94  of the first gimbal frame extended part  86 . Further, the first gimbal frame extended part  86  can be prevented from disengaging from the reinforcement member  100  in the “−Z” direction by the second reinforcement member protruded part  105 . 
     In addition, in this embodiment, the gimbal mechanism  7  includes the second connection mechanism  77  which turnably connects the gimbal frame  75  with the fixed body  8  around the second axis “R 2 ”. The gimbal frame  75  is provided with a pair of the second gimbal frame extended parts  87  which are protruded from the frame main body part to both sides in the second axis “R 2 ” direction and are extended in the “−Z” direction. A pair of the second gimbal frame extended parts  87  is located on the outer peripheral side with respect to the movable body  5 . Further, the fixed body  8  is provided with the frame part  110  which surrounds the movable body  5 , the turning support mechanism  6  and the gimbal frame  75  from the outer peripheral side. The second connection mechanism  77  includes the second support member  82 , which is protruded from each of the diagonal portions of the frame part  110  in the second axis “R 2 ” direction to a side of the gimbal frame  75  on the second axis “R 2 ”, and the second concave curved face  83  which is provided in each of a pair of the second gimbal frame extended parts  87  and is brought into contact with a tip end of the second support member  82 . Therefore, the turning support mechanism  6  is turnably supported by the gimbal mechanism  7  around the second axis “R 2 ”. 
     Further, in this embodiment, the inner peripheral face  51   a  of the frame part  110  is provided with the moving range restriction part  145  (a pair of the side faces  120   b  of the groove part  120 ) which faces the reinforcement member  100  with the first space interposed therebetween in the circumferential direction and is capable of abutting with the reinforcement member  100  to restrict a moving range of the gimbal frame  75  when the gimbal frame  75  is displaced in the circumferential direction. Further, the frame part  110  is provided with the turning range restriction part  146  (bottom face  120   a  of the groove part  120 ) which faces the reinforcement member  100  with the second space interposed therebetween in the first axis “R 1 ” direction and is capable of abutting with the reinforcement member  100  to restrict a turning range of the gimbal frame  75  when the gimbal frame  75  is turned around the second axis “R 2 ”. Therefore, in a case that an external force is applied or the like, a range that the gimbal frame  75  is moved in the circumferential direction and a range that the gimbal frame  75  is turned around the second axis “R 2 ” can be restricted. Accordingly, deformation and damage of the gimbal frame  75  can be prevented or suppressed. 
     Modified Embodiments 
       FIG. 14A  is an explanatory view showing a structure that the first support member  81  of the first connection mechanism  76  is fixed to the reinforcement member  100 , and  FIG. 14B  is an explanatory view showing a structure that the first support member  81  of the first connection mechanism  76  is fixed to the third extended portion  86   c  of the first gimbal frame extended part  86 . 
     As shown in  FIG. 14A , the first support member  81  may be fixed to the third reinforcement portion  100   c  of the reinforcement member  100 . In this case, the third extended portion  86   c  of the first gimbal frame extended part  86  is provided with no support member fixing tube part  93 . In the example shown in  FIG. 14A , in a state that the first support member  81  is inserted into the reinforcement member through-hole  103  and the gimbal frame extended part through-hole  92 , the first support member  81  is fixed to the reinforcement member  100  and the third extended portion  86   c  of the first gimbal frame extended part  86  and is protruded from the third extended portion  86   c  of the first gimbal frame extended part  86  to a side of the movable body  5 . In other words, the reinforcement member through-hole  103  and the gimbal frame extended part through-hole  92  have sizes that the first support member  81  is fitted, and the first support member  81  is press-fitted to the reinforcement member through-hole  103  and the gimbal frame extended part through-hole  92 . 
     According to this embodiment, the first support member  81  is held by the reinforcement member through-hole  103  and the gimbal frame extended part through-hole  92  which penetrate through in the first axis “R 1 ” direction. Therefore, the first support member  81  can be moved in the first axis “R 1 ” direction along the reinforcement member through-hole  103  and the gimbal frame extended part through-hole  92 . As a result, a protruding amount of the first support member  81  which is protruded from the first gimbal frame extended part  86  to a side of the movable body  5  can be adjusted and thus, a contact pressure of the first support member  81  with the first concave curved face  61  of the plate holder  42  can be adjusted. Further, when a protruding amount of the first support member  81  can be adjusted, a situation is easily avoided that the first support member  81  and the first concave curved face  61  of the plate holder  42  are separated from each other and the plate holder  42  is unable to be turnably supported by the gimbal frame  75 . 
     In the structure shown in  FIG. 14A , the gimbal frame extended part through-hole  92  may be formed larger than an outer diameter dimension of the first support member  81 . In this case, the first support member  81  is protruded from the third extended portion  86   c  of the first gimbal frame extended part  86  to a side of the movable body  5  in a state that the first support member  81  is not brought into contact with the third extended portion  86   c  of the first gimbal frame extended part  86 . In other words, the first support member  81  is fixed to the reinforcement member  100  in a state that the first support member  81  is inserted into the reinforcement member through-hole  103  which penetrates through the third reinforcement portion  100   c  in the first axis “R 1 ” direction. The first support member  81  fixed to the third reinforcement portion  100   c  is penetrated through the gimbal frame extended part through-hole  92  and is protruded from the third extended portion  86   c  of the first gimbal frame extended part  86  to a side of the movable body  5 . 
     Also in this case, the first support member  81  is held by the reinforcement member through-hole  103  which penetrates in the first axis “R 1 ” direction. Therefore, the first support member  81  can be moved in the first axis “R 1 ” direction along the reinforcement member through-hole  103 . As a result, a protruding amount of the first support member  81  which is protruded from the first gimbal frame extended part  86  to a side of the movable body  5  can be adjusted and thus, a contact pressure of the first support member  81  with the first concave curved face  61  of the plate holder  42  can be adjusted. Further, when a protruding amount of the first support member  81  can be adjusted, a situation is easily avoided that the first support member  81  and the first concave curved face  61  of the plate holder  42  are separated from each other and the plate holder  42  is unable to be turnably supported by the gimbal frame  75 . 
     Alternatively, as shown in  FIG. 14B , the first support member  81  may be fixed to the third extended portion  86   c  of the first gimbal frame extended part  86 . In this case, the reinforcement member  100  is provided with no reinforcement member through-hole  103 . On the other hand, the gimbal frame extended part through-hole  92  provided in the third extended portion  86   c  of the first gimbal frame extended part  86  has a size so that the first support member  81  is fitted. 
     In this embodiment, the first support member  81  is fixed to the third extended portion  86   c  of the first gimbal frame extended part  86  in a state that the first support member  81  is inserted into the gimbal frame extended part through-hole  92 . Fixing of the first support member  81  to the third extended portion  86   c  of the first gimbal frame extended part  86  may be performed by welding or the like. In this case, when the first support member  81  is to be fixed to the third extended portion  86   c  of the first gimbal frame extended part  86 , the first support member  81  may be structured of a spherical body similarly to the second support member  82  and fixed to the third extended portion  86   c  of the first gimbal frame extended part  86 . 
     While the description above refers to particular embodiments of the present invention, it will be understood that many modifications may be made without departing from the spirit thereof. The accompanying claims are intended to cover such modifications as would fall within the true scope and spirit of the present invention. 
     The presently disclosed embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims, rather than the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
