The position of the push button 70 is viewed from the inside of the fixed cylinder 50, and (d) is a view of the position of the push button 70 when the slider portion 62 is retracted from the outside of the fixed cylinder 50.
FIG. 14 is a perspective view of the third housing 80.
FIG. 15 is a perspective view of the fixed cylinder 50.

As shown in FIGS. 12 and 13, the push button 70 includes a shaft portion 71, a pressing portion 72 that covers one end of the shaft portion 71 (the radial outer side of the lens barrel 1), and a shaft portion 71 thereof. It includes a spring portion 73 attached to one end side and inside the pressing portion 72, and an engaging portion 74 provided at the other end of the shaft portion 71 (diameterally inside the lens barrel 1).
The shaft portion 71 of the push button 70 penetrates the hole 86 of the outer cylinder 85, the hole 81 of the third housing 80, and the push button guide elongated hole 54 of the fixed cylinder 50. The engaging portion 74 provided at the other end of the shaft portion 71 can be inserted into the push button engaging recess 62D of the slider portion 62 attached to the first housing 30.

When the pressing portion 72 of the push button 70 is pushed from the outside, the spring portion 73 contracts and the shaft portion 71 lowers (moves inward in the radial direction). Then, the engaging portion 74 is inserted into the push button engaging recess 62D of the slider portion 62.

When the lens barrel 1 is in the contracted state as shown in FIG. 12 (b), the slider portion 62 is contracted and the claw portion 33b of the body side leaf spring portion 33B is the claw portion as shown in FIG. 9 (b). It is engaged with the engagement recess 62C.

From this state, the lens barrel 1 is extended. Then, the push button 70 is pushed, and the engaging portion 74 of the push button 70 is inserted into the push button engaging recess 62D of the slider portion 62.
When the push button 70 is moved to the subject side in this state, the outer cylinder 85, the third housing 80, and the slider portion 62 are moved to the subject 2 side in the optical axis Z direction along the guide slot 31 of the first housing 30. Move to.
At this time, the claw portion 33b of the body side leaf spring portion 33B rides on the claw portion engaging recess 62C, and the slide side surface 62F of the slider portion 62 slides along the side surface 63C of the fixing portion 63B.

When the slider portion 62 moves to the subject side, the subject side yaw drive coil 61A also moves to the subject side, so that the distance between the subject side yaw drive coil 61A and the body side yaw drive coil 61B becomes longer.
Then, when the claw portion engaging recess 62C comes to the position of the claw portion 33b of the subject side leaf spring portion 33A, the claw portion 33b engages with the claw portion engaging recess 62C.

When the push button 70 is released, the push button 70 is raised by the urging force of the spring portion 73. The engaging portion 74 of the push button 70 is in a non-engaged state with the push button engaging recess 62D of the slider portion 62, but since the claw portion 33b is engaged with the claw portion engaging recess 62C, the slider portion 62 It is fixed.

When the slider portion 62 is extended in this way, the distance between the subject-side yaw drive coil 61A and the body-side yaw drive coil 61B becomes longer.
Then, the rotational moment around the yaw shaft member 66 generated when electric power is supplied to the subject side yaw drive coil 61A and the body side yaw drive coil 61B becomes large. Therefore, the first housing 30 and the second housing 10 can be driven in the yaw direction with respect to the fixed cylinder 50 with a larger force even if the supply power is the same, for example.

On the contrary, when the lens barrel 1 shown in FIG. 12A is in the extended state, the slider portion 62 is extended and the claw portion 33b of the subject side leaf spring portion 33A is extended as shown in FIG. 9A. It is engaged with the claw portion engaging recess 62C.
Then, the push button 70 is pushed, and the engaging portion 74 of the push button 70 is inserted into the push button engaging recess 62D of the slider portion 62.
When the push button 70 is moved to the body side in this state, the outer cylinder 85, the third housing 80, and the slider portion 62 move to the body side along the guide slot 31 of the first housing 30.
At this time, the claw portion 33b of the subject-side leaf spring portion 33A is disengaged from the claw portion engaging recess 62C, and the slide side surface 62F of the slider portion 62 slides along the side surface 63C of the fixing portion 63B.

When the slider portion 62 moves to the body side, the subject side yaw drive coil 61A also moves to the body side, so that the distance between the subject side yaw drive coil 61A and the body side yaw drive coil 61B becomes shorter.
Then, when the claw portion engaging recess 62C comes to the position of the claw portion 33b of the body side leaf spring portion 33B, the claw portion 33b engages with the claw portion engaging recess 62C. The engaging portion 74 of the push button 70 is in a non-engaged state with the push button engaging recess 62D of the slider portion 62.
At this time, the push button 70 is not engaged from the hole, but the claw portion 33b is engaged with the claw portion engaging recess 62C, so that the slider portion 62 is fixed.
As described above, when the slider portion 62 contracts, the distance between the subject-side yaw drive coil 61A and the body-side yaw drive coil 61B becomes shorter, and the lens barrel 1 can be brought into a contracted state.

(Third housing 80)
As shown in FIG. 14, the third housing 80 has a tubular shape in which a disk member 83 having an opening through which the second housing 10 can be inserted is integrally molded on the subject side.
A magnet and a yoke 82 for driving a first housing are attached to the subject side of the inner circumference of the third housing 80.

(Fixed cylinder 50)
As shown in FIG. 1, the lens barrel 1 includes a yaw direction rotation detection unit 61 that detects rotation in the yaw direction, a third blur detection unit 53, and an operation member 59. The third blur detection unit 53 is a gyro sensor or the like, and detects pitching and yawing of the camera system 3. The third blur detection unit 53 is preferably arranged on the yaw axis Y.
As shown in FIGS. 15 and 2, 3, 4, and 12, the fixed cylinder 50 includes a cylindrical portion and a disk member 56 integrally formed with the cylindrical portion and to which the lens side outer mount 55 is attached.
A first housing drive body magnet and a yoke 57 are attached to the body side of the inner circumference of the fixed cylinder 50.

(Spherical coil 58)
FIG. 16 is a partial cross-sectional view of the lens barrel 1. FIG. 17 is a perspective view showing the first housing 30 and the spherical coil 58 provided on the fixed cylinder 50.
As shown in FIG. 8 above, the first housing 30 has a substantially octagonal shape, but the two opposite surfaces of the set of which the pitch axis P passes through are curved rather than flat.

A first housing bearing 37 through which the pitch shaft member 24 described above is inserted is provided on this curved surface. As shown in FIG. 2, with the pitch shaft member 24 inserted in the first housing bearing 37, a spherical magnet 38 is attached to the outside of the pitch shaft member 24.

On the other hand, as shown in FIGS. 2, 16 and 17, a spherical coil 58 is attached to a position on the inner surface of the fixed cylinder 50 facing the spherical magnet 38.
The position where the spherical coil 58 and the spherical magnet 38 are attached is approximately 90 degrees with respect to the position where the yaw drive unit 60 is attached, that is, a position substantially intermediate between the two yaw drive units 60. Is provided with a spherical coil 58 and a spherical magnet 38.

The yaw auxiliary drive unit 90 that assists the yaw drive unit 60 is configured by the spherical coil 58 and the spherical magnet 38.
The spherical coil 58 and the spherical magnet 38 are preferably spherical surfaces having a radius centered on the vicinity of the intersection of the pitch axis P and the yaw axis Y, but are not limited thereto.
Further, although the spherical coil 58 and the spherical magnet 38 are used in the present embodiment, they may be curved surfaces curved only in the circumferential direction about the optical axis Z instead of the spherical surface.

FIG. 18 is a diagram illustrating the operation of the yaw drive unit 60 and the yaw auxiliary drive unit 90.
As described above, the yaw drive unit 60 includes the first housing drive subject side magnet and yoke 82, the subject side yaw drive coil 61A, the first housing drive body side magnet and yoke 57, and the body side yaw drive coil 61B. And.
Further, the yaw auxiliary drive unit 90 includes a spherical magnet 38 and a spherical coil 58 as described above.

When power is supplied to the subject-side yaw drive coil 61A and the body-side yaw drive coil 61B of the yaw drive unit 60, a driving force is generated in the direction indicated by the arrow in FIG. The body 10 is driven in the yaw direction with respect to the fixed cylinder 50.

At this time, if the lens barrel 1 is extended and the slider portion 62 is moved toward the subject and is extended, the distance between the yaw drive coil 61A on the subject side and the yaw drive coil 61B on the body side is a slider. It is longer than the case where the portion 62 is in the contracted state.
When the slider portion 62 is extended in this way, the rotational moment around the yaw shaft member 66 becomes large, so that the first housing 30 and the second housing 10 are driven in the yaw direction with respect to the fixed cylinder 50, for example. Even with the power supply, it can be done with a larger force.

Further, when electric power is also supplied to the spherical coil 58 of the yaw auxiliary drive unit 90, the drive in the yaw direction is assisted, and the drive in the yaw direction becomes easier.

Further, according to the present embodiment, since the spherical coil 58 is used, even if the first housing 30 and the second housing 10 rotate around the yaw axis as shown in FIG. 18, the spherical coil 58 and the spherical magnet 38 The relative distance to and from is constant, the driving force can be kept constant, and control is easy.

In the present embodiment, the spherical coil 58 and the spherical magnet 38 are arranged in the movement between the fixed cylinder 50 and the second housing 10, but the present invention is not limited to this, and the second housing 10 and the first housing 30 are used. A spherical coil and a magnet may be arranged in the drive of the above.

(Elastic member 89)
Return to FIG. As shown in the figure, an annular elastic member 89 is attached to the inner diameter side of the disk member 83 provided at the tip of the third housing 80 on the subject side.
The outer diameter side of the elastic member 89 is fixed to the disk member 83, and the inner diameter side extends further to the inner diameter side than the opening 83a of the disk member 83.
The end of the portion extending toward the inner diameter is in contact with the outer peripheral surface of the second housing 10.

On the other hand, a filter frame 17 is attached to the tip of the second housing 10. The filter frame 17 has a larger diameter than the second housing 10, and the filter frame 17 protrudes from the side surface of the second housing 10.
As shown in FIG. 12B, this protruding portion presses the subject side of the portion extending toward the inner diameter side of the elastic member 89 when the lens barrel 1 is in the contracted state.
By this pressing, for example, when the lens barrel 1 is in the contracted state, moisture and dust are prevented from entering between the second housing 10, the third housing 80, and the outer cylinder 85.
Further, the movement and wobbling of the second housing 10 when the power is not applied are suppressed by pressing the elastic member 89.

On the other hand, when the lens barrel 1 is extended, the end portion of the elastic member 89 extending toward the inner diameter side is in contact with the outer peripheral surface of the second housing 10, but is strongly pressed. Since it is not in a state, it does not hinder the movement of the second housing 10 during zooming or focusing.

If you want to turn off the VCM even when the power of the camera body 2 is on, temporarily fix the lens barrel 1 side with the elastic member 89, and place the image sensor 101 on the camera body 2 side with a stepping motor or the like. It can be fixed with.

Further, when the power of the camera body 2 is ON and the VCM is OFF and it is desired to be completely fixed on the lens barrel 1 side, the DC motor 201 and the worm gear 202 may be provided as in the modified form shown in FIG. can.
FIG. 19 is a diagram showing a modified form in which the support portion 40 (second housing 10) is completely fixed to the fixed cylinder 50 on the lens barrel 1 side.

As shown in the figure, in the modified form, the DC motor 201 and the worm gear 202 are attached to the fixed cylinder 50 of the lens barrel 1. Further, a lock ring 203 is rotatably attached around a cylindrical portion 94 provided with a lens-side inner mount 9 of the second housing 10.
A gear portion 204 is formed around the lock ring 203, and a gear member 205 is arranged between the worm gear 202 and the gear portion 204.

At the time of locking, the DC motor 201 is driven to rotate the worm gear 202, and the lock ring 203 is rotated via the gear member 205 and the gear portion 204.
Then, the protrusion 206 provided on the inner peripheral side of the lock ring 203 comes into contact with the protrusion 207 provided on the outer peripheral side of the tubular portion 94 of the lens side inner mount 9 of the second housing 10 and presses the protrusion 207. ..
As a result, the support portion 40 (second housing 10) is fixed.

When the lock is released, the DC motor 201 is driven in the reverse direction to rotate the worm gear 202, and the lock ring 203 is rotated in the reverse direction via the gear member 205 and the gear portion 204.
Then, the protrusion 206 provided on the inner peripheral side of the lock ring 203 and the protrusion 207 provided on the outer peripheral side of the cylindrical portion 94 of the lens side inner mount 9 of the second housing 10 are in a non-contact state. , The fixing of the support portion 40 (second housing 10) is released.

(Arrangement of FPC)
21 (a) and 21 (b) are diagrams illustrating the arrangement of flexible printed boards (FPCs) connected to the pitch drive unit 20, the yaw drive unit 60, and the yaw auxiliary drive unit 90.

As shown in FIGS. 5 (b) and 21 (a) and 21 (b), the FPC 600 connected to the yaw drive unit 60 includes an optical axis extending portion 60A and a circumferential curved portion 60B.
The extending portion 60A in the optical axis direction extends from the inner mount 9 on the lens side toward the subject.
The circumferential curved portion 60B is connected to the subject-side end portion of the optical axis extending portion 60A. Then, the circumferentially curved portion 60B once extends to the opposite side of the yaw drive portion 60 in the circumferential direction, then curves at R1.0 or higher (becomes a loop) to change direction, and extends in the yaw drive portion 60 direction. ing.

Further, the FPC 201 connected to the pitch drive unit 20 includes an optical axis extending portion 20A, a circumferential curved portion 20B, an optical axis extending portion 20C, and a connecting portion 20D.
The extending portion 20A in the optical axis direction extends toward the subject from the inner mount 9 on the lens side.
The circumferential curved portion 20B is connected to the axial subject-side end portion of the optical axis extending portion 20A. Then, the circumferentially curved portion 20B extends to the opposite side of the pitch drive portion 20 in the circumferential direction, then curves at R1.0 or higher (becomes a loop), changes direction, and extends in the pitch drive portion 20 direction.
The optical axis extending portion 20C is connected to the circumferential curved portion 20B, is parallel to the optical axis extending portion 20A, and extends at a position closer to the pitch driving portion 20 than the optical axis extending portion 20A.
The connecting portion 20D extends from the extending portion 20C in the optical axis direction to the pitch driving portion 20.

In the present embodiment, the FPC connected to the yaw auxiliary drive unit 90 includes an optical axis extending portion 90A extending from the lens side inner mount 9 toward the subject side.

According to the present embodiment, as shown in FIG. 5B, the FPC 600 includes a circumferentially curved portion 60B having a circumferential slack in a radial cross section (XY plane). Further, due to this slack in the circumferential direction, there is a margin for allowing movement in the optical axis Z direction.
Therefore, when the second housing 10 and the first housing 30 move in the yaw direction with respect to the fixed cylinder 50, the movement is not hindered, and an unreasonable force is applied to the FPC 600 to break the FPC. Problem does not occur.

Further, since the FPC 201 includes a circumferential curved portion 20B having a slack in the circumferential direction, the second housing 10 may hinder the movement when the second housing 10 moves in the pitch direction with respect to the fixed cylinder 50 and the first housing 30. In addition, there is no problem that the FPC is broken due to an unreasonable force applied to the FPC.

Further, the first housing is substantially octagonal and has a plane substantially orthogonal to the diagonal line. Further, the fixed cylinder 50 also has a plane substantially orthogonal to the diagonal line as shown in FIG. 5 (b).
Since the FPCs 600 and 201 are fixed on these planes, they can be fixed more firmly than when they are fixed on a curved surface.

It should be noted that there is a slack of the FPC arranged between the first housing 30 and the second housing 10, and a slack of the FPC arranged between the first housing 30 and the fixed cylinder 50, and each of them has a slack. The slack is an arrangement / orientation substantially opposite to the diagonal line.
In this way, the slacks are arranged at a plurality of diagonal portions and are arranged so as to face each other with respect to the optical axis Z. As a result, the urging forces of the FPC 600 and 201 on the first housing 30 and the second housing 10 are canceled each other, and it is easy to balance the forces.
It should be noted that the arrangement may be such that the X-axis or the Y-axis is opposed to the reference.

FIG. 29 is an interlocking diagram of the locking levers 153 and 154 when the lens side mount 100 is connected to the body mount 200.

(A) Step 1
The lens side mount 100 and the body mount 200 are not yet coupled.
The locking lever drive pin 100d is located away from both locking levers 153 and 154.
The locking lever drive pin 100e is located at the same position in the circumferential direction as the slide plate portion 153b of the first locking lever 153, but is not in contact with the slide plate portion 153b, and is located at a position away from the second locking lever 154.

(B) Step 2
It is a state rotated 35 degrees from the state of step 1.
The locking lever drive pin 100e comes into contact with the inner surface of the second locking lever 154 and moves along the inner surface thereof. However, what is the contact portion between the inner surface of the second locking lever 154 and the locking lever drive pin 100e? , The second locking lever 154, which is at the same distance from the optical axis Z, does not move.
The locking lever drive pin 100d comes into contact with the outer surface of the slide plate portion 153b of the first locking lever 153 and moves along the outer surface thereof, but the outer surface of the slide plate portion 153b is in contact with the locking lever drive pin 100d. Since the portion is at the same distance from the optical axis Z, the first locking lever 153 does not move.

(C) Step 3
It is a state rotated by 45 degrees from the state of step 1.
The locking lever drive pin 100e starts contact with the inner surface of the front portion 154ba of the second locking lever 154. The front end portion of the front portion 154ba is bent inward (in the direction in which the diameter from the optical axis becomes smaller) than the connection portion with the rear portion 154bb.
Therefore, since the locking lever drive pin 100e moves a certain distance from the optical axis Z, the tip portion 154ba of the second locking lever 154 is pushed outward.
As a result, the second locking lever 154 rotates clockwise in the figure about the fixed shaft 154a (arrow r1).
Then, the claw portion 154d moves outward, and the claw portion 154d separates from the first holder 112 as shown in FIG. 25 (b).
At this time, the locking lever drive pin 100d is in contact with the outer surface of the slide plate portion 153b of the first locking lever 153, but since the outer surface has a constant diameter from the optical axis Z, the first locking lever 153 Does not move.

(D) Step 4
It is a state rotated by 50 degrees from the state of step 1.
Since the locking lever drive pin 100e pushes the tip portion 154ba of the second locking lever 154 outward, the claw portion 154d moves outward, and the claw portion 154d is the first holder as shown in FIG. 25 (b). Keep away from 112.
At this time, the locking lever drive pin 100d starts contact with the outer surface of the front portion 153ba of the slide plate portion 153b.
The front end portion of the front portion 153ba is bent outward (in the direction in which the diameter from the optical axis becomes larger) than the connection portion with the rear portion 153bb.
Therefore, the locking lever drive pin 100d pushes the outer surface of the front portion 154ba of the locking lever 15 inward. As a result, the first locking lever 153 rotates counterclockwise in the figure about the fixed shaft 154a (arrow r2).

(E) Step 5
It is a state rotated by 60 degrees from the state of step 1.
Since the locking lever drive pin 100e pushes the tip portion 154ba of the second locking lever 154 outward, the claw portion 154d moves outward, and the claw portion 154d is the first holder as shown in FIG. 25 (b). Keep away from 112.
Since the locking lever drive pin 100d pushes the tip portion 153ba of the first locking lever 153 inward, the claw portion 153d moves outward, and the claw portion 153d is the first holder as shown in FIG. 25 (b). Keep away from 112.
When the second pin comes off, the photo reflector reacts. The reaction of the photoreflector triggers the stepping motor 158 shown in FIG. 28 to start driving, the release plate 163 is lowered to the rear as shown in FIG. 28, and the body inner shell 110 and the body outer shell 150 are separated. ..

According to the present embodiment, a lens barrel that is removable from the image pickup unit and is connected to a body outer shell 150 that includes the image pickup element 101, and a subject image is formed with respect to the image pickup element 101. It has a lens group L to image and a support portion 40 that supports at least a part of the lenses of the lens group L, and the support portion 40 is removable from the image pickup element 101 and with respect to the optical axis of the lens group L. It is possible to provide a lens barrel that can rotate and move relative to the fixed barrel 50 about two or more axes that are substantially orthogonal to each other.
The image sensor 101 is fixed to the outer shell 150 of the body when the lens barrel 1 is not attached, but is not fixed to the outer shell 150 of the body when the lens barrel 1 is attached. It becomes a state, a so-called detached state.

According to the present embodiment, the locking configuration of the inner shell 110 of the body and the outer shell 150 of the body is composed of both the thrust direction and the radial direction. Then, the mechanical locking between the body inner shell 110 and the body outer shell 150 is gradually released by the rotational operation of the existing lens mounting.
The inner shell 110 of the body is connected to the second housing 10 of the lens barrel 1, and the outer shell 150 of the body is connected to the fixed cylinder 50 of the lens barrel 1. The body inner shell 110, together with the second housing 10 of the lens barrel 1, rotates and yaws around the pitch axis P of the second housing 10 with respect to the body outer shell 150 and the fixed cylinder 50 of the lens barrel 1. Rotation around the axis Y is possible.

Here, in the case of moving images, the types of still images and blurs are different. Also, since the image is taken for a long time, the angle of blur is large. Therefore, there is a demand for an increase in the image stabilization angle that can be corrected. However, according to the present embodiment, it is possible to provide a lens barrel capable of correcting a large blur in a lens barrel that can be attached to and detached from the image pickup unit.

If the locking operation and the unlocking operation are performed by one operation, the movable block 111 mounted on the image sensor, which is not locked at all, is fixed at the same time from both sides, which is difficult to fix.
However, according to the present embodiment, the locking operation and the unlocking operation of the body inner shell 110 and the body outer shell 150 are held stepwise by two or more continuous operations, so that they are easy to fix.

Further, the camera body 2 of the embodiment includes a body-side inner mount 109 and a body-side outer mount 151. However, even when a lens barrel that does not have a lens-side inner mount is attached, the lens-side mount can be attached to and detached from the body-side outer mount 151. Therefore, a lens barrel that does not have an internal mount on the lens side can also be attached.
The locking configuration between the body-side inner mount 109 (body inner shell 110) and the body-side outer mount 151 (body outer shell 150, body fixing portion) is not particularly limited, and mechanical locking as in the present embodiment is not particularly limited. In addition, it may be configured to be locked by electromagnetic force.
