Abstract:
The purpose of the present invention is to provide an optical unit with camera-shake correction function capable of minimizing the load applied to a movable element from a flexible wiring substrate even when the movable element is oscillated, in order to correct camera shake. In an optical unit provided with a camera-shake correction function, a movable element can be oscillated about an oscillation support point by actuating a drive mechanism for camera-shake correction, and camera shake can therefore be corrected. In a flexible wiring substrate drawn out from the movable element, a folded part folded along the rear end portion of the movable element in the optical axis direction is formed in a drawn-out portion from the movable element, and in the optical axis direction, the oscillation support point is positioned between the surface of the folded part that faces the end part on the other side −Y in the Y-axis direction of the rear end portion of the movable element in the optical axis direction, and the surface that faces toward the rear in the optical axis direction at a fixed part of the flexible wiring substrate with respect to a fixed body.

     FIELD OF THE INVENTION 
       [0002]    The present invention relates to an optical unit with a shake correcting function which is mounted on a cell phone with a camera or the like. 
       BACKGROUND 
       [0003]    In recent years, a cell phone is structured as an optical device on which an optical unit for photographing is mounted. In the optical unit, in order to restrain disturbance of a photographed image due to a shake of hand of a user, a technique has been proposed in which a movable body provided with optical elements such as a lens and an imaging element is swingably supported by a fixed body, and the movable body is swung based on a detection result of the shake by using an angular velocity sensor, a photo reflector or the like (see Patent Literature 1). 
         [0004]    In Patent Literature 1, in order to electrically connect an imaging element with the outside, a structure has been proposed in which a flexible wiring board is connected with a movable body and the flexible wiring board is extended to the outer side from a fixed body. Further, a structure has been proposed in which a flexible wiring board is curved in a “C”-character shape so that, when a movable body is to be swung, the flexible wiring board does not apply a useless load to the movable body. 
         [0005]    Japanese Patent Laid-Open No. 2010-96861 
         [0006]    However, like a structure described in Patent Literature 1, in a structure that a dimension of a flexible wiring board is set longer by forming the flexible wiring board to be curved in a “C”-character shape for reducing a load which is applied to a movable body from the flexible wiring board, a large space is required to secure on a rear side in an optical axis direction of the movable body. Therefore, a dimension in the optical axis direction of the optical unit is large. 
       SUMMARY 
       [0007]    In view of the problem described above, at least an embodiment of the present invention provides an optical unit with a shake correcting function in which, even when the movable body is swung for correcting a shake, a load applied to the movable body from the flexible wiring board is capable of being restrained small. 
         [0008]    In order to attain the above, at least an embodiment of the present invention provides an optical unit with a shake correcting function including a movable body which holds an optical element, a fixed body which covers the movable body, a flexible wiring board which is extended from the movable body to an outer side with respect to the fixed body, a swing support point which is provided between a rear end portion in an optical axis direction of the movable body and the fixed body, and a shake correction drive mechanism which swings the movable body with the swing support point as a swing center. The flexible wiring board is provided with a bent part, which is bent along the rear end portion in the optical axis direction of the movable body in a lead-out portion from the movable body, and a fixed part which is fixed to the fixed body in an extended portion from the fixed body to the outer side, and the swing support point is located in the optical axis direction between a face of the bent part facing the rear end portion in the optical axis direction of the movable body and a face of the fixed part which faces a rear side in the optical axis direction. 
         [0009]    In at least an embodiment of the present invention, the optical unit with a shake correcting function is provided with a shake correction drive mechanism structured to swing the movable body and thus, when a shake such as a shake of hand is occurred in the optical unit, the movable body can be swung to cancel the shake. Therefore, even when the optical unit is shaken, the inclination of the optical axis can be corrected. Further, a flexible wiring board is extended from the movable body and the flexible wiring board is provided with a bent part. The bent part is structured so as to be bent along the rear end portion in the optical axis direction of the movable body in a lead-out portion from the movable body. Therefore, different from a case that the flexible wiring board is curved in a “C”-character shape, the flexible wiring board is not curved largely and thus a narrow space is sufficient for disposing and extending the flexible wiring board on the rear side in the optical axis direction of the movable body. Further, the bent part is structured so that the lead-out portion from the movable body is bent along the rear end portion in the optical axis direction of the movable body, and the flexible wiring board is provided with the fixed part which is fixed to the fixed body in the extended portion from the fixed body to the outer side. Therefore, the flexible wiring board is capable of being displaced only in the portion from the bent part to the fixed part. However, in at least an embodiment of the present invention, the swing support point is located in the optical axis direction between a face of the bent part, which faces the rear end portion in the optical axis direction of the movable body, and a face of the fixed part which faces the rear side in the optical axis direction and thus, even when the movable body is swung, displacement of the flexible wiring board is small. Accordingly, when the movable body is swung, a load which is applied to the movable body by the flexible wiring board is small. 
         [0010]    In at least an embodiment of the present invention, it is preferable that the flexible wiring board is provided with branched parts, which are divided so as to pass through on both sides of the swing support point, between the bent part and the fixed part. According to this structure, when the movable body is swung, a load which is applied to the movable body by the flexible wiring board is small and thus, the movable body can be swung appropriately. 
         [0011]    In at least an embodiment of the present invention, it is preferable that the branched parts are ended before the fixed part viewed from a side where the swing support point is located. According to this structure, different from a case that the branched parts are utilized as the fixed part, a difference of the length dimension of the branched parts does not occur. Therefore, the branched parts do not apply an unnecessary load to the movable body. 
         [0012]    In at least an embodiment of the present invention, it may be structured that the flexible wiring board is bent only through the bent part between a connected part with the movable body and the fixed part, and a portion between the bent part and the fixed part is extended so as to obliquely intersect the optical axis direction. 
         [0013]    In at least an embodiment of the present invention, it may be structured that the flexible wiring board is bent only through the bent part between a connected part with the movable body and the fixed part, and a portion between the bent part and the fixed part is extended so as to be perpendicular to the optical axis direction. 
         [0014]    In at least an embodiment of the present invention, it is preferable that the movable body includes a rigid plate on the rear end portion in the optical axis direction and the rigid plate is supported by the fixed body through the swing support point. According to this structure, even when an impact is applied to the movable body through the swing support point, the movable body can be prevented from being damaged. 
         [0015]    In at least an embodiment of the present invention, it may be structured that an imaging element is provided on a front side with respect to the rigid plate in the optical axis direction. According to this structure, even when an impact is applied to the movable body through the swing support point, the imaging element can be protected. 
         [0016]    In at least an embodiment of the present invention, it may be structured that the bent part is fixed to a face of the rigid plate on a rear side in the optical axis direction with an adhesive. 
         [0017]    In at least an embodiment of the present invention, it is preferable that a region of the rigid plate where the flexible wiring board is bonded is formed by a stepped part which is protruded from its surrounding area, and the region is formed with a groove-shaped recessed part. According to this structure, even when an impact is applied to the movable body through the swing support point, the flexible wiring board can be prevented from being detached from the movable body. 
         [0018]    In this case, it is preferable that the flexible wiring board is fixed to the rigid plate with an adhesive, and a region of the rigid plate where the flexible wiring board is bonded is formed by a stepped part which is protruded from its surrounding area, and the region is formed with a groove-shaped recessed part. According to this structure, since the groove-shaped recessed part functions as a reservoir part for the adhesive, the flexible wiring board and the rigid plate can be surely bonded to each other. Further, the region of the rigid plate where the flexible wiring board is bonded is formed by a stepped part which is protruded from its surrounding area and thus, the flexible wiring board can be bonded at a predetermined position. 
         [0019]    In at least an embodiment of the present invention, it is preferable that corner portions on both sides in a widthwise direction of the bent part are formed to be cut off in an inclined shape or an “R”-shape, and corner portions on both sides in a widthwise direction of an end part of the rigid plate on an opposite side to the bent part are formed to be cut off in an inclined shape or an “R”-shape. According to this structure, when the movable body is to be swung, a corner edge of the bent part of the flexible wiring board and a corner edge of the rigid plate can be prevented from contacting with the fixed body and thus, a swing range of the movable body can be increased. 
         [0020]    In at least an embodiment of the present invention, the optical unit with a shake correcting function is provided with a shake correction drive mechanism structured to swing the movable body and thus, when a shake such as a shake of hand is occurred in the optical unit, the movable body can be swung to cancel the shake. Therefore, even when the optical unit is shaken, an inclination of the optical axis can be corrected. Further, the flexible wiring board is extended from the movable body and the flexible wiring board is provided with a bent part. The bent part is structured so as to be bent along the rear end portion in the optical axis direction of the movable body in a lead-out portion from the movable body. Therefore, different from a case that the flexible wiring board is curved in a “C”-character shape, the flexible wiring board is not curved largely and thus a narrow space is sufficient for disposing and extending the flexible wiring board on the rear side in the optical axis direction of the movable body. Further, the bent part is structured so that the lead-out portion from the movable body is bent along the rear end portion in the optical axis direction of the movable body, and the flexible wiring board is provided with the fixed part which is fixed to the fixed body in the extended portion from the fixed body to the outer side. Therefore, the flexible wiring board is capable of being displaced only in the portion from the bent part to the fixed part. However, in at least an embodiment of the present invention, the swing support point is located in the optical axis direction between a face of the bent part, which faces the rear end portion in the optical axis direction of the movable body and a face of the fixed part which faces the rear side in the optical axis direction and thus, even when the movable body is swung, displacement of the flexible wiring board is small. Accordingly, when the movable body is swung, a load which is applied to the movable body by the flexible wiring board is small and thus the movable body can be swung appropriately.

Specifically, the first holder  71  is fixed to front side faces in the optical axis direction “L” of the permanent magnets  520  and the second holder  72  is fixed to rear side faces in the optical axis direction “L” of the permanent magnets  520 . The permanent magnets  520 , the first holder  71  and the second holder  72  structure a permanent magnet assembly  75  in a rectangular tube shape. Therefore, after the photographing unit  1  is inserted into an inner side of the rectangular tube-shaped permanent magnet assembly  75 , an outer peripheral face of the case  14  of the photographing unit  1  and the inner peripheral face of the permanent magnet assembly  75  (inner faces of the permanent magnets  520 ) are fixed to each other by an adhesive or the like and, as a result, the permanent magnets  520 , the first holder  71 , the second holder  72 , the stopper member  8  and the photographing unit  1  are integrated with each other to structure the movable body  3 . 
       (Structure of Spring Member  600 ) 
       [0042]    The spring member  600  is a plate-shaped spring member which is provided with a fixed side connecting part  620  in a rectangular frame shape which is connected with the fixed body  200 , a movable side connecting part  610  which is connected with the movable body  3 , and a plurality of arm parts  630  which are extended between the movable side connecting part  610  and the fixed side connecting part  620 . Both ends of the arm part  630  are respectively connected with the movable side connecting part  610  and the fixed side connecting part  620 . In this embodiment, the fixed side connecting part  620  is provided with a main body portion  621  in a rectangular frame shape and protruded parts  622  which are protruded to outer sides at middle positions of side portions of the main body portion  621 . 
         [0043]    In order to connect the spring member  600  with the movable body  3  and the fixed body  200 , in this embodiment, the movable side connecting part  610  is fixed to the rear side end face in the optical axis direction “L” of the stopper member  8  by a method such as welding. Further, the fixed side connecting part  620  is fixed to upper end parts of the side plate parts  720  of the lower cover  700  by a method such as welding in a state that the protruded parts  622  are fitted to the cut-out portions  218  and  219  of the upper cover  250 . The spring member  600  is made of nonmagnetic metal such as beryllium copper or nonmagnetic SUS steel material and is formed by performing press working or etching processing using a photo lithography technique on a thin plate having a certain thickness. 
         [0044]    In this embodiment, when the movable side connecting part  610  of the spring member  600  is connected with the movable body  3  and the fixed side connecting part  620  is fixed to the fixed body  200 , the movable body  3  is set in a pushed-up state to the front side in the optical axis direction “L” by the swing support point  180 . Therefore, the movable side connecting part  610  of the spring member  600  is in a pushed-up state to the front side in the optical axis direction “L” with respect to the fixed side connecting part  620  and thus the arm parts  630  of the spring member  600  urges the movable body  3  to the rear side in the optical axis direction “L”. Accordingly, the movable body  3  is in a state urged toward the swing support point  180  by the spring member  600  and the movable body  3  is in a supported state by the fixed body  200  so as to be capable of swinging through the swing support point  180 .

Specifically, the flat plate-shaped permanent magnet  520  is fixed to each of four outer faces of the case  14  in the movable body  3  and the coil part  560  is disposed on an inner face of the rectangular tube-shaped body part  210  of the upper cover  250  (fixed body  200 ). The outer face side and the inner face side of the permanent magnet  520  are magnetized in different poles from each other. Further, the permanent magnet  520  is comprised of two magnet pieces which are disposed in the optical axis direction “L” and the faces of the magnet pieces facing the coil part  560  are magnetized in different poles from each other in the optical axis direction “L”. Further, the coil part  560  is formed in a substantially quadrangular frame shape and its upper and lower long side portions are utilized as an effective side. 
         [0047]    The permanent magnet  520  and the coil part  560  which are disposed at two positions interposing the movable body  3  on both sides in the “Y”-axis direction structure a “Y”-side shake correction drive mechanism and, as shown by the arrows “X1” and “X2” in  FIG. 5(   a ), the “Y”-side shake correction drive mechanism swings the movable body  3  with an axial line “X0” passing through the swing support point  180  and extending in the “X”-axis direction as a swing center. Further, the permanent magnet  520  and the coil part  560  which are disposed at two positions interposing the photographing unit  1  on both sides in the “X”-axis direction structure an “X”-side shake correction drive mechanism and the “X”-side shake correction drive mechanism swings the movable body  3  with an axial line passing through the swing support point  180  and extending in the “Y”-axis direction as a swing center. 
         [0048]    In order to structure the shake correction drive mechanism  500  (“Y”-side shake correction drive mechanism and “X”-side shake correction drive mechanism), in this embodiment, a sheet-shaped coil body  550  is used which is extended along four inner faces of the upper cover  250 . In the sheet-shaped coil body  550 , four coil parts  560  are integrally formed with each other at a predetermined interval. Further, when the sheet-shaped coil body  550  is developed, the sheet-shaped coil body  550  is provided with a shape extending in a belt shape and is fixed to the inner face of the upper cover  250  by a method such as surface bonding in a state that the sheet-shaped coil body  550  is bent so as to be along the four inner faces of the upper cover  250 . 
         [0049]    The sheet-shaped coil body  550  is structured so that the coil part  560  made of a minute copper wiring line is formed on a printed circuit board by utilizing an electric conduction wiring technique. A plurality of copper wiring layers (coil part  560 ) is formed in multi-layer through an insulation film. Further, the surface of the copper wiring line (coil part  560 ) is covered with an insulation film. For example, an FP coil (fine pattern coil (registered mark)) made by ASAHI KASEI ELECTRONICS CO., LTD. may be used as the sheet-shaped coil body  550 . 
         [0050]    As shown in  FIG. 3(   b ), a plurality of terminal parts  565  is formed on one of four faces of the sheet-shaped coil body  550  bent in a rectangular shape by an electrically conducting layer extended from four coil parts  560 . In this embodiment, the terminal parts  565  are disposed on an outer side of the sheet-shaped coil body  550  which is opposite to the inner side facing the permanent magnet  520 . The terminal parts  565  are electrically connected with the flexible wiring board  450  disposed so as to superpose on the sheet-shaped coil body  550  from the outer side and electrical power is supplied through the flexible wiring board  450 . 
         [0051]    In this embodiment, as described above, since the sheet-shaped coil body  550  is used, in comparison with a case that discrete air-core coils are separately used, a space between the photographing unit  1  and the fixed body  200  can be narrowed. Therefore, the size of the optical unit  100  can be made small. Further, in the case of the sheet-shaped coil body  550 , since a plurality of the coil parts  560  is integrally provided with the terminal parts  565 , even when a plurality of coil parts  560  are required to be disposed around the optical axis, the sheet-shaped coil body  550  can be extended around the optical axis. Therefore, different from a case that discrete air-core coils are separately used, discrete air-core coils are not required to be disposed at plural positions around the optical axis and discrete air-core coils are not required to be electrically connected and thus, according to this embodiment, assembly man-hours are reduced. Further, the terminal parts  565  of the sheet-shaped coil body  550  are disposed on the outer side which is an opposite side to the permanent magnet  520  and thus electrical connection with the coil parts  560 , in other words, connection of the flexible circuit board  450  with the terminal parts  565  can be performed easily. 
         [0052]    The flexible wiring board  450  is provided with a first portion  451  and a second portion  452  which are perpendicularly bent so as to superpose on a face on one side, i.e., the “+X” side in the “X”-axis direction of the sheet-shaped coil body  550  and a face on one side, i.e., the “+Y” side in the “Y”-axis direction from the outer side. An end part  453  which is bent at a rear side end part in the optical axis direction “L” of the second portion  452  is connected with the flexible wiring board  410  on an outer side. 
         [0053]    In this embodiment, portions of the sheet-shaped coil body  550  which are superposed on the first portion  451  and the second portion  452  of the flexible wiring board  450  are formed with rectangular windows  558  and  559 . Further, a first photo reflector  580  and a second photo reflector  590  are mounted on faces on the inner sides of the first portion  451  and the second portion  452  of the flexible wiring board  450  at positions superposed on the windows  558  and  559 . The first photo reflector  580  and the second photo reflector  590  are located in insides of the windows  558  and  559  of the sheet-shaped coil body  550 . Therefore, when the optical unit  100  is assembled, a light emitting part and a light receiving part of the first photo reflector  580  face a side face of the movable body  3  (side face of the case  14 ) in the “X”-axis direction, and a light emitting part and a light receiving part of the second photo reflector  590  face a side face of the movable body  3  (side face of the case  14 ) in the “Y”-axis direction. 
       (Structure of Stopper Mechanism) 
       [0054]    In the optical unit  100  in this embodiment, the movable body  3  is supported by the fixed body  200  in a state that the movable body  3  is capable of swinging through the swing support point  180 . Therefore, when a large force is applied from the outside to displace the movable body  3  largely, the arm parts  630  of the spring member  600  may be plastically deformed. In order to prevent this problem, in this embodiment, a stopper mechanism which will be described below is provided. 
         [0055]    In this embodiment, as described with reference to  FIGS. 4(   a ) and  4 ( b ) and  FIGS. 5(   a ) and  5 ( b ), the stopper member  8  in a rectangular frame shape is fixed to the rear side end face in the optical axis direction “L” of the second holder  72  of the movable body  3  by a method such as welding. The stopper member  8  is provided with a main body portion  80  in a rectangular frame shape and protruded parts  81  which are protruded from the main body portion  80  toward the outer side. The protruded parts  81  protrude to outer sides with respect to the permanent magnets  520 . In this embodiment, the protruded part  81  is formed in each of four side portions of the main body portion  80 . Further, the protruded part  81  is provided in each of four side portions of the main body portion  80  at two positions separated in an extended direction of the side portion. In this embodiment, the protruded part  81  is provided in the vicinity of both ends of four side portions of the main body portion  80  (near the corner of the main body portion  80 ). 
         [0056]    The protruded part  81  faces the lower end portion of the sheet-shaped coil body  550  provided on the fixed body  200  through a narrow gap space “G1” (see  FIG. 5(   a )) on both sides in the “X”-axis direction and on both sides in the “Y”-axis direction. Therefore, the protruded parts  81  and the sheet-shaped coil body  550  structure a stopper mechanism  810  between the shake correction drive mechanism  500  and the swing support point  180  in the optical axis direction “L” for determining a movable range when the movable body  3  is displaced in a direction perpendicular to the optical axis direction “L”. More specifically, the protruded parts  81  and the sheet-shaped coil body  550  structure the stopper mechanism  810  between the shake correction drive mechanism  500  and the spring member  600  in a space between the shake correction drive mechanism  500  and the swing support point  180  in the optical axis direction “L” for determining a movable range when the movable body  3  is displaced in the direction perpendicular to the optical axis direction “L”. 
         [0057]    In a case of the sheet-shaped coil body  550 , different from an air-core coil, a wound coil is not loosened even when the coil is abutted with the permanent magnet  520 . Therefore, a portion with which the protruded part  81  is abutted may be either of a portion of the sheet-shaped coil body  550  where the coil part  560  is structured and a portion where the coil part  560  is not structured. However, in this embodiment, a portion with which the protruded part  81  is abutted is set to be a portion of the sheet-shaped coil body  550  where the coil part  560  is not structured. 
         [0058]    Further, the sheet-shaped coil body  550  and the permanent magnet  520  are oppositely disposed to each other through a narrow gap space “G2” and the gap space “G2” is a slightly larger than the gap space “G1” between the protruded part  81  and the sheet-shaped coil body  550 . Therefore, the sheet-shaped coil body  550  and the permanent magnets  520  structure a stopper mechanism  820  which determines a swing range when the movable body  3  is swung. A portion of the sheet-shaped coil body  550  with which the permanent magnets  520  is abutted may be either of a portion where the coil part  560  is structured and a portion where the coil part  560  is not structured. However, in this embodiment, a portion of the sheet-shaped coil body  550  with which the permanent magnets  520  are abutted is set to be a portion where the coil part  560  is structured. According to the stopper mechanism  820 , a swing range of the movable body  3  can be set with a high degree of accuracy. In other words, in the shake correction drive mechanism  500 , a distance between the sheet-shaped coil body  550  and the permanent magnet  520  is set with a high degree of accuracy and thus, when the stopper mechanism  820  is structured by utilizing the sheet-shaped coil body  550  and the permanent magnet  520 , a swing range of the movable body  3  is set with a high degree of accuracy. 
         [0059]    As described above, in this embodiment, the protruded part  81  protruded from one of the fixed body  200  and the movable body  3  is capable of being abutted with the other of the fixed body  200  and the movable body  3  and, in this manner, the stopper mechanism  810  is provided for determining the movable range when the movable body  3  is displaced in the direction perpendicular to the optical axis direction “L”. Specifically, in this embodiment, the stopper mechanism  810  is provided for determining the movable range when the movable body  3  is displaced in the direction perpendicular to the optical axis direction “L” by abutting the protruded part  81  protruded from the movable body  3  with the fixed body  200  side. Therefore, even when an impact is applied to the movable body  3  to displace the movable body  3  in the direction perpendicular to the optical axis direction “L”, the movable range of the movable body  3  is restricted. Accordingly, the spring member  600  is prevented from being plastically deformed and being damaged. Further, the protruded part  81  (stopper mechanism  810 ) is provided between the shake correction drive mechanism  500  and the swing support point  180  in the optical axis direction “L”. Therefore, the stopper mechanism  810  is operated with a little displaced amount of the movable body  3  and thus the plastic deformation of the spring member  600  is prevented surely. Further, the protruded part  81  (stopper mechanism  810 ) is provided between the shake correction drive mechanism  500  and the spring member  600  in the optical axis direction “L”. Therefore, the movable range when the movable body  3  is displaced in the direction perpendicular to the optical axis direction “L” is restricted further narrow and thus the plastic deformation of the spring member  600  is prevented further surely. 
         [0060]    Further, the protruded part  81  is protruded from the movable body  3  to the sheet-shaped coil body  550  side with respect to the permanent magnet  520  so as to be abutted with the sheet-shaped coil body  550 . Therefore, the movable range when the movable body  3  is displaced in the direction perpendicular to the optical axis direction “L” can be set with a high degree of accuracy and thus the movable range when the movable body  3  is displaced in the direction perpendicular to the optical axis direction “L” is restricted without disturbing the swing of the movable body  3 . In other words, in the shake correction drive mechanism  500 , a distance between the sheet-shaped coil body  550  and the permanent magnet  520  is set with a high degree of accuracy and thus, when it is structured so that the protruded part  81  is abutted with the sheet-shaped coil body  550 , a distance between the protruded part  81  and the sheet-shaped coil body  550  is also set with a high degree of accuracy. Accordingly, the movable range when the movable body  3  is displaced in the direction perpendicular to the optical axis direction “L” is set with a high degree of accuracy. Further, the protruded part  81  is provided at two positions separated from each other in each of four side portions of a quadrangular shape. Therefore, when the stopper mechanism  810  is operated, since a force in the twisting direction is not applied to the movable body  3 , the spring member  600  is prevented from being plastically deformed in the twisting direction. 
       (Shake Correcting Operation) 
       [0061]    In the optical unit  100  in this embodiment, when the optical device  1000  shown in  FIG. 1  is shaken, the shake is detected by a gyroscope and the host control section controls the shake correction drive mechanism  500  based on a detection result by the gyroscope. In other words, a drive current for cancelling the shake which is detected by the gyroscope is supplied to the coil parts  560  of the sheet-shaped coil body  550  through the flexible wiring board  410  and the flexible wiring board  450 . As a result, the shake correction drive mechanism  500  swings the photographing unit  1  around the “Y”-axis with the swing support point  180  as a swing center. Further, the shake correction drive mechanism  500  swings the photographing unit  1  around the “X”-axis with the swing support point  180  as the swing center. Further, when the swing around the “X”-axis and the swing around the “Y”-axis of the photographing unit  1  are combined with each other, the photographing unit  1  is displaced over the entire “X-Y” plane. Accordingly, all shakes occurred in the optical unit  100  can be corrected surely. 
         [0062]    When the photographing unit  1  is to be driven, the displacement of the photographing unit  1  is monitored by the first photo reflector  580  and the second photo reflector  590  shown in  FIG. 3(   b ). In other words, a distance variation to the movable body  3  is obtained on the basis of a detection result by the first photo reflector  580  when the movable body  3  is driven by the shake correction drive mechanism  500  and is turned around the axial line extended in the “Y”-axis direction passing through the swing support point  180 , and thus displacement in the “X”-axis direction of the movable body  3  can be monitored. Further, a distance variation to the movable body  3  is obtained on the basis of a detection result by the second photo reflector  590  when the movable body  3  is driven by the shake correction drive mechanism  500  and is turned around the axial line extended in the “X”-axis direction passing through the swing support point  180 , and thus displacement in the “Y”-axis direction of the movable body  3  can be monitored. Therefore, displacements of the movable body  3  when turned around the axial lines can be monitored and thus turnings of the movable body  3  around the axial lines can be controlled. 
       (Structure of Flexible Wiring Board  420  and Rigid Plate  30 ) 
       [0063]      FIGS. 6(   a ) and  6 ( b ) are perspective views showing the optical unit  100  with a shake correcting function in accordance with the first embodiment of the present invention which is viewed from the rear side in the optical axis direction “L”.  FIG. 6(   a ) is an exploded perspective view showing a state that the lower cover  700  is detached from the optical unit  100  with a shake correcting function and  FIG. 6(   b ) is an exploded perspective view showing a state that the rigid plate  30  is separately shown. 
         [0064]    As shown in  FIGS. 3(   a ) and  3 ( b ),  FIGS. 4(   a ) and  4 ( b ),  FIGS. 5(   a ) and  5 ( b ), and  FIGS. 6(   a ) and  6 ( b ), in the optical unit  100  in this embodiment, one end part of the flexible wiring board  420  is connected with the photographing unit  1  of the movable body  3 . Therefore, in a case that the movable body  3  is to be swung, if the flexible wiring board  420  applies a large load to the movable body  3 , the movable body  3  is not swung appropriately. 
         [0065]    In order to prevent such a problem, the flexible wiring board  420  is provided with the following structure. In other words, the flexible wiring board  420  is provided with a connected part  426 , which is connected with the photographing unit  1  on an inner side of the movable body  3 , and an imaging element  1   b  is mounted on a surface on the front side in the optical axis direction “L” of the connected part  426 . 
         [0066]    Further, the flexible wiring board  420  is led out from a side face of the movable body  3  on the other side “−Y” in the “Y”-axis direction and the flexible wiring board  420  is provided with a bent part  422 , which is bent toward one side “+Y” in the “Y”-axis direction along the rear end portion in the optical axis direction “L” of the movable body  3 , in the vicinity of a lead-out portion  421  from the movable body  3 . Further, the flexible wiring board  420  is extended toward one side “+Y” in the “Y”-axis direction from the bent part  422  and is extended out to an outer side from the fixed body  200 . The flexible wiring board  420  is provided with a fixed part  424 , which is fixed to the fixed body  200  with an adhesive, at a portion extended from the fixed body  200 . In this embodiment, the flexible wiring board  420  is adhesively bonded on the bottom plate part  710  of the lower cover  700  of the fixed body  200  at a portion located on the one side “+Y” in the “Y”-axis direction and at a position superposed on the end part of the rectangular tube-shaped body part  210  and the bonded portion is the fixed part  424 . A tip end side of the flexible wiring board  420  with respect to the fixed part  424  is an extended portion  425  from the fixed body  200  and a reinforcing plate  439  is adhesively bonded on the extended portion  425 . 
         [0067]    In the flexible wiring board  420 , the bent part  422  and the fixed part  424  are located at different positions from each other in the “Z”-axis direction. More specifically, the fixed part  424  is located on one side “+Z” in the “Z”-axis direction with respect to the bent portion  422 . Therefore, a portion  423  of the flexible wiring board  420  between the bent part  422  and the fixed part  424  is extended so as to obliquely intersect the optical axis direction “L”. Therefore, a point of the swing support point  180  where the movable body  3  and the fixed body  200  are contacted with each other (point of the pivot  181 ) is located in the “Z”-axis direction between a face  422   a  of the bent part  422 , which faces an end part on the other side “−Y” in the “Y”-axis direction of the rear end portion in the optical axis direction “L” of the movable body  3 , and a face  424   b  of the fixed part  424  which faces the rear side in the optical axis direction “L”. 
         [0068]    The portion  423  of the flexible wiring board  420  extended toward the fixed part  424  from the bent part  422  is overlapped with the portion where the swing support point  180  is provided. Therefore, in this embodiment, the flexible wiring board  420  is provided with branched parts  423   b  and  423   c , which are divided by a slit  423   a  so as to pass through on both sides of the swing support point  180 , in the portion  423  between the bent part  422  and the fixed part  424  and thus, the swing support point  180  is located on an inner side of the slit  423   a . In this embodiment, the slit  423   a  is extended to the fixed part  424  of the flexible wiring board  420 . As described above, in this embodiment, the flexible wiring board  420  is formed in a relatively wide width but the branched parts  423   b  and  423   c  passing through on both sides of the swing support point  180  are formed in two strip-shaped portions whose width dimension is narrow. 
         [0069]    In this embodiment, the movable body  3  includes a rigid plate  30  which is made of a metal plate or the like. The rigid plate  30  is joined to a rear side face in the optical axis direction “L” of the connected part  426  of the flexible wiring board  420  with the movable body  3  (connected part with the photographing unit  1 ) by an adhesive  48  or the like, and the rigid plate  30  structures a rear side end part in the optical axis direction “L” of the movable body  3 . Therefore, the imaging element  1   b  is located on the front side in the optical axis direction “L” with respect to the rigid plate  30 . Further, the rigid plate  30  is sandwiched between the connected part  426  connected with the photographing unit  1  and the portion  423  between the bent part  422  and the fixed part  424 . 
         [0070]    The movable body  3  is supported by the swing support point  180  through the rigid plate  30 . A protruded part  38  protruded to the rear side in the optical axis direction “L” is formed at the middle of the rigid plate  30  and an end face of the protruded part  38  which is located on its rear side in the optical axis direction “L” is formed as a receiving part  182  with which the pivot  181  structuring the swing support point  180  is abutted. 
         [0071]    In this embodiment, the bent part  422  of the flexible wiring board  420  is fixed to a face  35  on the rear side in the optical axis direction “L” of the rigid plate  30  by an adhesive  39 . Further, a region  31  of the rigid plate  30  where the flexible wiring board  420  is bonded is formed as a stepped part  31   c  where the region  31  is protruded from its surrounding area. Specifically, a recessed part  31   b  is formed in a strip shape on the face  35  on the rear side in the optical axis direction “L” of the rigid plate  30  along the end part on the other side “−Y” in the “Y”-axis direction. Further, a groove-shaped opening part  37  which is extended in parallel with the recessed part  31   b  is formed on one side “+Y” in the “Y”-axis direction with respect to the recessed part  31   b  on the face  35  on the rear side in the optical axis direction “L” of the rigid plate  30 . The portion sandwiched by the opening part  37  and the recessed part  31   b  is the region  31  where the flexible wiring board  420  is bonded. Further, the region  31  where the flexible wiring board  420  is bonded is formed with a groove  31   a  which is extended along a longitudinal direction (“X”-axis direction) of the region  31  in the middle in a short-side direction (“Y”-axis direction) of the region  31 . The groove  31   a  is used as a reservoir part for the adhesive  39 . Therefore, the bent part  422  of the flexible wiring board  420  is surely fixed to the face  35  of the rigid plate  30  on the rear side in the optical axis direction “L” by the adhesive  39  and thus, even when an impact is applied to the movable body  3  through the swing support point  180 , the flexible wiring board  420  is prevented from being detached from the movable body  3 . Further, the region  31  where the flexible wiring board  420  is bonded is structured with the stepped part  31   c  as a region protruded from its surrounding area. Therefore, the flexible wiring board  420  is surely bonded at a predetermined position of the rigid plate  30 . 
         [0072]    In this embodiment, both side portions  422   g  in a widthwise direction of the bent part  422  are formed so that their corners are cut off in an inclined shape or an “R”-shape. Therefore, corner portions of the rigid plate  30  are exposed on both side portions  422   g  in a widthwise direction of the bent part  422 . Accordingly, in a case that the movable body  3  is swung, even when the bent part  422  of the flexible wiring board  420  is displaced together with the movable body  3 , a swing range of the movable body  3  is set to be wider in comparison with a case that the corner portions of the rigid plate  30  are covered by the flexible wiring board  420 . 
         [0073]    Further, both side portions  30   b  in a widthwise direction of the rigid plate  30  on the end part on an opposite side to the bent part  422  are formed so that their corners are cut off in an inclined shape or an “R”-shape. Accordingly, when the movable body  3  is to be swung, a swing range of the movable body  3  is set to be wider in comparison with a case that both side portions  30   b  of the rigid plate  30  are formed in a rectangular shape. 
       Principal Effects in this Embodiment 
       [0074]    As described above, in the optical unit  100  in this embodiment (optical unit with a shake correcting function), the movable body  3  is swingably supported by the swing support point  180  of the fixed body  200  and thus, when the shake correction drive mechanism  500  is operated, the movable body  3  is swung with the swing support point  180  as a swing center. Accordingly, even when a shake is occurred in the optical unit  100  due to a shake of hand or the like, the shake can be corrected by swinging the movable body  3 . 
         [0075]    Further, the flexible wiring board  420  is led out from the movable body  3  and the flexible wiring board  420  is provided with one bent part  422 , which is bent along the rear end portion in the optical axis direction “L” of the movable body  3  in the lead-out portion  421  of the flexible wiring board  420  from the movable body  3 . Therefore, different from a case that the flexible wiring board  420  is curved in a “C”-character shape, the flexible wiring board  420  is not curved largely and thus a narrow space is sufficient for disposing and extending the flexible wiring board  420  on the rear side in the optical axis direction “L” of the movable body  3 . 
         [0076]    Further, the bent part  422  is structured so that the lead-out portion  421  from the movable body  3  is bent along the rear end portion in the optical axis direction “L” of the movable body  3 , and the flexible wiring board  420  is provided with the fixed part  424  which is fixed to the fixed body  200  in the extended portion from the fixed body  200  to the outer side. Therefore, the flexible wiring board  420  is capable of being displaced only in the portion from the bent part  422  to the fixed part  424 . However, in this embodiment, in the “Z”-axis direction (direction of the optical axis), a point of the swing support point  180  (point of the pivot  181 ) where the movable body  3  and the fixed body  200  are contacted with each other is located between the face  422   a  of the bent part  422 , which faces the end part on the other side “−Y” in the “Y”-axis direction of the rear end portion in the optical axis direction “L” of the movable body  3  and the face  424   b  which faces the rear side in the optical axis direction “L” of the fixed part  424 . Therefore, even when the movable body  3  is swung, displacement of the flexible wiring board  420  is small. Accordingly, when the movable body  3  is swung, since a load which is applied to the movable body  3  by the flexible wiring board  420  is small, the movable body  3  is swung appropriately. 
         [0077]    Further, although the flexible wiring board  420  is formed so as to have a considerably wider width, the branched parts  423   b  and  423   c  which are passed through on both sides of the swing support point  180  are formed to be two strip-shaped portions whose width dimension is narrow. Therefore, when the flexible wiring board  420  is displaced, since a load which is applied to the movable body  3  by the flexible wiring board  420  is small, the movable body  3  is swung appropriately. 
         [0078]    In addition, the movable body  3  is provided with the rigid plate  30  on the rear end portion in the optical axis direction “L”, and the rigid plate  30  is supported by the fixed body  200  through the swing support point  180 . Therefore, even when an impact is applied to the movable body  3  through the swing support point  180 , the movable body  3  is prevented from being damaged. Further, the imaging element  1   b  is provided on the front side in the optical axis direction “L” with respect to the rigid plate  30  and thus, even when an impact is applied to the movable body  3  through the swing support point  180 , the imaging element  1   b  can be protected. 
       Second Embodiment 
       [0079]      FIG. 7  is an exploded perspective view showing a state that a lower cover  700  is detached from an optical unit  100  with a shake correcting function in accordance with a second embodiment of the present invention which is viewed from a rear side in an optical axis direction. Basic structures in the second embodiment is similar to the first embodiment and thus, the same reference signs are used in the common portions and their descriptions are omitted. 
         [0080]    In the first embodiment, as described with reference to  FIGS. 6(   a ) and  6 ( b ), the slit  423   a  for forming the branched parts  423   b  and  423   c  is extended to the fixed part  424  of the flexible wiring board  420 . However, in the second embodiment, as shown in  FIG. 7 , the slit  423   a  and the branched parts  423   b  and  423   c  are ended before the fixed part  424  viewing from a side where the swing support point  180  is located. According to this structure, different from a case that the branched parts  423   b  and  423   c  are utilized as the fixed part, a difference of the length dimensions of the branched parts  423   b  and  423   c  does not occur. Therefore, the branched parts  423   b  and  423   c  do not apply a useless load to the movable body  3 . 
       Third Embodiment 
       [0081]      FIGS. 8(   a ) and  8 ( b ) are cross-sectional views showing an optical unit  100  with a shake correcting function in accordance with a third embodiment of the present invention.  FIG. 8(   a ) is a “YZ” cross-sectional view showing an optical unit  100  and  FIG. 8(   b ) is an enlarged cross-sectional view showing a bent portion of a flexible wiring board  420 . Basic structures in the third embodiment is similar to the first embodiment and thus, the same reference signs are used in the common portions and their descriptions are omitted. 
         [0082]    In the first embodiment, a portion between the opening part  37  and the recessed part  31   b  of the face  35  on the rear side in the optical axis direction “L” of the rigid plate  30  is set to be a region  31  where the flexible wiring board  420  is bonded. However, in the third embodiment, as shown in  FIGS. 8(   a ) and  8 ( b ), a recessed part  422   e  is formed instead of the opening part  37 . Also in this structure, a region  31  where the flexible wiring board  420  is bonded is formed by a stepped part  31   c  for protruding the region  31  from the surrounding area and thus the flexible wiring board  420  can be surely bonded to a predetermined position of the rigid plate  30 . 
       Fourth Embodiment 
       [0083]      FIGS. 9(   a ) and  9 ( b ) are explanatory views showing an optical unit  100  with a shake correcting function in accordance with a fourth embodiment of the present invention.  FIG. 9(   a ) is its perspective view and  FIG. 9(   b ) is its cross-sectional view.  FIGS. 10(   a ),  10 ( b ) and  10 ( c ) are explanatory views showing the optical unit  100  with a shake correcting function in accordance with the fourth embodiment of the present invention which is viewed from a rear side in an optical axis direction.  FIG. 10(   a ) is an exploded perspective view showing a state that a lower cover  700  is detached from an optical unit  100  and which is viewed from a rear side in an optical axis direction “L”,  FIG. 10(   b ) is an exploded perspective view showing a state that a flexible wiring board  420  is detached from a movable body and which is viewed from a rear side in an optical axis direction “L”, and  FIG. 10(   c ) is an exploded perspective view showing a state that a rigid plate  30  is detached from the flexible wiring board  420  and which is viewed from the rear side in the optical axis direction “L”. Basic structures in the fourth embodiment is similar to the first embodiment and thus, the same reference signs are used in the common portions and their descriptions are omitted. 
         [0084]    At least an embodiment of the present invention may be applied to an optical unit  100  with a shake correcting function which is shown in  FIGS. 9(   a ) and  9 ( b ), and  FIGS. 10(   a ),  10 ( b ) and  10 ( c ). Even in the optical unit  100  with a shake correcting function shown in  FIGS. 9(   a ) and  9 ( b ), and  FIGS. 10(   a ),  10 ( b ) and  10 ( c ), similarly to the first embodiment, one end part of the flexible wiring board  420  is connected with the photographing unit  1  of the movable body  3 . The flexible wiring board  420  is provided with a connected part  426  connected with the photographing unit  1  on an inner side of the movable body  3  and an imaging element  1   b  is mounted on a face on a front side in the optical axis direction “L” of the connected part  426 . In this embodiment, the connected part  426  is formed in a structure that a metal plate is adhesively fixed to an end part of the flexible wiring board  420  to increase rigidity. 
         [0085]    Further, the flexible wiring board  420  is extended from a side face of the movable body  3  on the other side “−Y” in the “Y”-axis direction, and the flexible wiring board  420  is provided with a bent part  422  which is bent toward one side “+Y” in the “Y”-axis direction along a rear end portion in the optical axis direction “L” of the movable body  3  in a lead-out portion  421  of the flexible wiring board  420  from the movable body  3 . Further, the flexible wiring board  420  is extended from the bent part  422  toward one side “+Y” in the “Y”-axis direction and then extended from the fixed body  200  to the outer side. 
         [0086]    In this embodiment, a vertical plate part  261  of a support plate  260  in an “L”-character shape is fixed to a side face of the fixed body  200  on one side “+Y” in the “Y”-axis direction and a fixed part  424  of the flexible wiring board  420  is fixed to a horizontal plate part  262  of the support plate  260  with an adhesive or the like. Therefore, in the flexible wiring board  420 , the bent part  422  and the fixed part  424  are located at the same position in the “Z”-axis direction. Accordingly, the portion  423  between the bent part  422  and the fixed part  424  of the flexible wiring board  420  is extended so as to be perpendicular to the optical axis. 
         [0087]    Even in the flexible wiring board  420  structured as described above, similarly to the first embodiment, a position of the swing support point  180  where the movable body  3  and the fixed body  200  are contacted with each other (position of the pivot  181 ) is located between the face  422   a  of the bent part  422 , which faces the end part on the other side “−Y” in the “Y”-axis direction in the rear end portion in the optical axis direction “L” of the movable body  3 , and the face  424   b  of the fixed part  424  which faces the rear side in the optical axis direction “L” in the “Z”-axis direction. 
         [0088]    The portion  423  of the flexible wiring board  420  which is extended from the bent part  422  toward the fixed part  424  is overlapped with the portion where the swing support point  180  is provided. Therefore, in this embodiment, the portion  423  of the flexible wiring board  420  between the bent part  422  and the fixed part  424  is provided with the branched parts  423   b  and  423   c  in a strip shape, which are divided so as to pass through on both sides of the swing support point  180  by the slit  423   a , and the swing support point  180  is located on an inner side of the slit  423   a . In this embodiment, the slit  423   a  is extended to a tip end side with respect to the fixed part  424  of the flexible wiring board  420  to reach to a midway position of the extended portion  425  from the fixed body  200  to the outer side. 
         [0089]    The movable body  3  includes a rigid plate  30 . The rigid plate  30  is joined with a face of the connected part  426  of the flexible wiring board  420  on a rear side in the optical axis direction “L” with an adhesive  48  or the like, and the rigid plate  30  structures a rear side end part in the optical axis direction “L” of the movable body  3 . Therefore, an imaging element  1   b  is located on a front side in the optical axis direction “L” with respect to the rigid plate  30 . Further, the movable body  3  is supported by the swing support point  180  through the rigid plate  30 . A protruded part  38  which is protruded to a rear side in the optical axis direction “L” is formed in the middle of the rigid plate  30 . An end face of the protruded part  38  which is located on a rear side in the optical axis direction “L” is formed as a receiving part  182  with which the pivot  181  structuring the swing support point  180  is abutted. 
         [0090]    In this embodiment, the bent part  422  of the flexible wiring board  420  is fixed to the face  35  of the rigid plate  30  on the rear side in the optical axis direction “L” through a flexible adhesive sheet  36 . Further, a region  31  of the rigid plate  30  where the flexible wiring board  420  is bonded is formed through a stepped part  31   f  where the region  31  is protruded from its surrounding area. Specifically, the face  35  of the rigid plate  30  on the rear side in the optical axis direction “L” is formed with a groove-shaped recessed part  31   e  which is extended in parallel with an end part of the rigid plate  30  on the other side “−Y” in the “Y”-axis direction. Therefore, the region  31  where the flexible wiring board  420  is fixed is structured through the stepped part  31   f  as a region protruded from its surrounding area. Accordingly, the flexible wiring board  420  is surely fixed to a predetermined position of the rigid plate  30 . 
       Other Embodiments 
       [0091]    In the embodiments described above, the present invention is, as an example, applied to the optical unit  100  which is used in a cell phone with a camera. However, at least an embodiment of the present invention may be applied to the optical unit  100  which is used in a thin digital camera or the like. Further, in the embodiment described above, a lens drive mechanism and the like are structured in the photographing unit  1 . However, at least an embodiment of the present invention may be applied to a fixed focus type optical unit in which the lens drive mechanism is not mounted on the photographing unit  1 . 
         [0092]    In the embodiments described above, the pivot  181  of the swing support point  180  is structured in the fixed body  200 . However, the pivot  181  of the swing support point  180  may be formed in the movable body  3 . 
         [0093]    In addition, other than a cell phone, a digital camera and the like, the optical unit  100  with a shake correcting function to which at least an embodiment of the present invention is applied may be fixed in an apparatus such as a refrigerator in which vibration is occurred in a certain interval and mounted so as to be capable of being remote controlled. According to the apparatus, a service can be provided in which information in the inside of the refrigerator is obtained at a visit place, for example, at the time of shopping. According to this service, the camera system is provided with an attitude stabilizing device, a stable image can be transmitted even when vibration may occur in the refrigerator. Further, this device may be fixed to a device such as a bag, a satchel or a cap of a child and a student which is carried at a time of commuting or attending school. In this case, states of surroundings are photographed at a constant interval and, when the image is transmitted to a predetermined server, the parent or the like watches the image at a remote place to secure security of the child. In this application, without conscious of a camera, a clear image is photographed even when vibration occurs at the time of moving. Further, when a GPS is mounted in addition to a camera module, the position of a target person can be obtained simultaneously and thus, when an accident occurs, its position and situation can be confirmed immediately. In addition, when the optical unit  100  with a shake correcting function to which at least an embodiment of the present invention is applied is mounted at a position which is capable of photographing toward a front side in a car, it can be used as a drive recorder.

Further, when this image is distributed while interlocking with traffic jam information in the VICS (Vehicle Information and Communication System) of a car navigation system, the situation of a traffic jam can be provided further in detail. According to this service, similarly to a drive recorder mounted on a car, the situation when an accident has occurred can be recorded by a third person of passer-by without intention to utilize an inspection of the situation. Further, a clear image can be acquired without affected by vibration of a car. In a case of the application, when a power supply is turned on, a command signal is outputted to the control section and the shake control is started on the basis of the command signal. 
         [0094]    Further, the optical unit  100  with a shake correcting function to which at least an embodiment of the present invention is applied may be applied to shake correction of an optical device from which a light beam is emitted such as a laser beam pointer, a portable or on-vehicle projection display device and direct viewing type display device. Further, in an observation system with a high magnification such as an astronomical telescope system or a binocular system, the optical unit  100  may be used to observe without using an auxiliary locking device such as three-legged supports. In addition, when at least an embodiment of the present invention is applied to a rifle or a turret of a tank, its attitude can be stabilized against vibration at the time of trigger and thus hitting accuracy can be enhanced.
