The limiting member 112 restricts the intermediate mount 100 from rotating in the second direction 30 opposite to the first direction 20 while the mount module 300 is engaged with the intermediate mount 100. The button 111 switches between a state in which the limiting member 112 restricts the rotation of the intermediate mount 100 in the second direction 30 and a state in which the rotation is not restricted.

The operation body 114 has a rotation axis 113 along the direction in which the button 111 is pressed. The direction in which the button 111 is pressed is the second direction 30 in which the intermediate mount 100 is rotated when the mount module 300 is removed from the intermediate mount 100. The operation body 114 holds the limiting member 112 so as to be rotatable about the rotation shaft 113. When the limiting member 112 rotates about the rotation shaft 113, the end portion 1121 of the limiting member 112 moves in the direction of the rotation center of the intermediate mount 100.

FIG. 13 is an enlarged view of the inner peripheral surface in the opening 531 of the base portion 530. The base portion 530 has an inner peripheral surface 5321 whose distance from the center of rotation of the intermediate mount 100 is the first distance in the opening 531 for accommodating the intermediate mount 100, and a distance from the center of rotation of the intermediate mount 100 is longer than the first distance. It has an inner peripheral surface 5322 and a boundary surface 5323 connecting the inner peripheral surface 5321 and the inner peripheral surface 5322. The end portion 1121 is a boundary surface 5323 between the inner peripheral surface 5321 and the inner peripheral surface 5322 of the base portion 530, and the movement in the second direction 30 is restricted.

FIG. 14A is a perspective view of the button 111 and the limiting member 112 as viewed from the front. FIG. 14B is a perspective view of the button 111 and the limiting member 112 as viewed from the back surface. The button 111 has a pressing surface 1113 that is pressed in the second direction 30, and a protrusion 1112 on the back side of the pressing surface 1113. The limiting member 112 has an inclined surface 1122 at a position corresponding to the protrusion 1112. When the pressing surface 1113 of the button 111 is pressed, the protrusion 1112 moves along the inclined surface 1122, and the limiting member 112 rotates about the rotation shaft 113. When the limiting member 112 rotates, the end 1121 moves toward the center of rotation of the intermediate mount 100. The protrusion 1112 of the button 111 and the inclined surface 1122 of the limiting member 112 function as a cam structure that changes the linear motion of the button 111 into the rotational motion of the limiting member 112. The other end 1123 of the limiting member 112 is urged by an elastic member 116 such as a spring so that the end 1121 moves in a direction opposite to the direction of the rotation center of the intermediate mount 100.

FIG. 15 shows a portion of the operating member 110 in the BB cross section shown in FIG. 10A. FIG. 16 shows a portion of the operating member 110 in the GG cross section shown in FIG. 10E.

FIG. 17A is an external view of the image pickup apparatus 500 as viewed from the side. FIG. 17B shows the MM cross section shown in FIG. 17A in a state where the engaging portion 303 of the mount module 300 is not yet engaged with the engaging portion 107 of the intermediate mount 100. FIG. 17C shows an MM cross section shown in FIG. 17A in a state where the engaging portion 303 of the mount module 300 is engaged with the engaging portion 107 of the intermediate mount 100. FIG. 18 is a view of the operating member 110 as viewed from the back surface side of the fixing member 102. The operating member 110 has a claw portion 115 that restricts the back movable member 104 and the front movable member 106 from rotating with respect to the fixing member 102. The claw portion 115 extends from the outer peripheral side surface of the front movable member 106 toward the rotation center of the intermediate mount 100 beyond the back surface of the rear movable member 104 to the back surface of the fixing member 102. A groove 1023 that limits the movement of the claw portion 115 is provided on the back surface of the fixing member 102.

In a state where the engaging portion 303 of the mount module 300 is not yet engaged with the engaging portion 107 of the intermediate mount 100, the end 1121 of the limiting member 112 is urged by the elastic member 116 and the inner circumference of the base portion 530. It is in contact with surface 5321. As shown in FIG. 17B, when the claw portion 115 reaches the boundary of the groove 1023 on the back surface of the fixing member 102 in the first direction 20, the claw portion 115 comes into contact with the end of the groove 1023, and the intermediate mount 100 is further first. It cannot rotate in the direction 20.

The end portion 1121 is urged by the elastic member 116 in a direction away from the center of rotation of the intermediate mount 100, and when the intermediate mount 100 rotates in the first direction 20, it moves while contacting the inner peripheral surface 5321. After that, when the end portion 1121 reaches the boundary surface 5323 between the inner peripheral surface 5321 and the inner peripheral surface 5322, the end portion 1121 moves to the inner peripheral surface 5322 side at the boundary surface 5323 by the urging force of the elastic member 116. do. When the end portion 1121 exceeds the boundary surface 5323 and reaches the inner peripheral surface 5322, the engaging portion 303 of the mount module 300 is in a state of being engaged with the engaging portion 107 of the intermediate mount 100.

When the mount module 300 is engaged with the intermediate mount 100 and the button 111 is not pressed, the end 1121 of the limiting member 112 comes into contact with the boundary surface 5323 and moves to the second direction 30 of the intermediate mount 100. Rotation is restricted. When the button 111 is pressed, the limiting member 112 rotates about the rotation shaft 113, and the end 1121 moves toward the rotation center of the intermediate mount 100. As a result, the end portion 1121 can move beyond the boundary surface 5323 on the inner peripheral surface 5321 in the second direction 30.

When the user mounts the mount module 300 on the intermediate mount 100, the user rotates the intermediate mount 100 in the first direction 20 while pinching the operating member 110 with his / her fingers. At this time, the end portion 1121 of the limiting member 112 can move along the inner peripheral surface 5321 of the base portion 530 without pressing the button 111. On the other hand, when the user removes the mount module 300 from the intermediate mount 100, the intermediate mount 100 is rotated in the second direction 30 while pinching the operating member 110 with a finger. Since the pressing surface 1113 of the button 111 is in a position where it is easily pressed in the second direction 30, when the user tries to rotate the intermediate mount 100 in the second direction 30 while pinching the operation member 110, the user can easily use his / her finger. The pressing surface 1113 can be pressed. Therefore, the user can easily release the restriction on the rotation of the limiting member 112 in the second direction 30, and can rotate the intermediate mount 100 in the second direction 30.

Here, when the user picks up the operation member 110 and tries to rotate the intermediate mount 100, it is preferable that the user holds down the image pickup device 500 so that the image pickup device 500 does not move. Therefore, as shown in FIGS. 19 and 20, the housing 501 may have recesses 118 on both side surfaces of the first direction 20 and the second direction 30 to assist the operation of the operating member 110. The shape of the recess 118 may be the same as the shape of the knob portion of the operating member 110. Since the operating member 110 moves above the housing 501, recesses 118 may be provided on both sides above the housing 501. For example, the user picks the operation member 110 with the thumb and index finger of the left hand while holding both recesses 118 with the thumb and index finger of the right hand. Then, while pressing the pressing surface 1113 of the button 111 with the thumb of the left hand, the intermediate mount 100 is rotated in the second direction 30. As a result, the engagement between the engaging portion 303 of the mount module 300 and the engaging portion 107 of the intermediate mount 100 is released, and the mount module 300 can be removed from the intermediate mount 100. The user does not pick the operating member 110 with his / her finger, but simply presses the pressing surface 1113 of the operating member 110 or the surface opposite to the pressing surface 1113 with his / her finger to push the intermediate mount 100 into the first direction 20 or the second. It may be rotated in the direction 30.

As shown in FIG. 20, the mount module 300 has a lock pin 360 and a button structure 350 including a button 352. The lock pin 360 is inserted into a hole provided in the mount of the interchangeable lens 10 to lock the rotation of the interchangeable lens 10. The button 352 is mechanically coupled to the lock pin 360 to switch from the state in which the lock pin 360 is inserted into the hole to the state in which the lock pin 360 is not inserted into the hole.

FIG. 22 is a view of the button structure 350 portion of the mount module 300 disassembled and viewed from the front side. FIG. 23 is a view of the button structure 350 portion of the mount module 300 disassembled and viewed from the rear side. The button 352 is fixed to one end of the L-shaped connecting member 354. The button 352 is fixed to one end of the connecting member 354 extending from the vicinity of the outer peripheral edge of the mount module 300 toward the front surface side along the direction of the rotation axis of the intermediate mount 100. The lock pin 360 is fixed to the other end of the connecting member 354. The lock pin 360 is fixed to the other end of the connecting member 354 extending in the direction of the rotation axis of the intermediate mount 100 from the vicinity of the outer peripheral edge of the mount module 300. The lock pin 360 is urged in a direction protruding from the front surface of the mount body 302 by the elastic member 3521 arranged directly under the button 352 and the elastic member 3522 arranged directly under the lock pin 360. The elastic members 3521 and 3522 may be springs or the like. When the interchangeable lens 10 is mounted on the mount module 300, the lock pin 360 is pushed by the mount surface of the interchangeable lens 10 so that it does not protrude from the front surface of the mount body 302.

When the interchangeable lens 10 rotates to a predetermined position, the lock pin 360 moves to the position of a hole provided in the mount surface of the interchangeable lens 10, and the urging force of the elastic member causes the lock pin 360 to move to the mount body 302. It protrudes from the front surface and is inserted into a hole in the mounting surface of the interchangeable lens 10. In this state, the lock pin 360 becomes a barrier and the interchangeable lens 10 cannot rotate. That is, the interchangeable lens 10 cannot be removed from the mount module 300.

When the button 352 is pressed, the lock pin 360 does not protrude from the front surface of the mount body 302. As a result, the lock pin 360 does not become a barrier, and the interchangeable lens 10 can rotate. That is, the interchangeable lens 10 can be removed from the mount module 300.

Unless the mount module 300 has a structure that can be attached to and detached from the base portion 530, the intermediate mount 100 does not exist. In this case, the button 352 for unlocking the lock pin 360 can be provided on the base portion 530. However, since the mount module 300 according to the present embodiment is removable and the intermediate mount 100 also exists, the button 352 cannot be provided on the base portion 530.

Therefore, in the present embodiment, the button structure 350 is provided in the mount module 300. The button structure 350 is provided on the mount module 300 so as to protrude outward from the outer peripheral edge of the mount module 300. If the button 352 is provided as close to the center of rotation of the intermediate mount 100 as possible, the interchangeable lens 10 becomes an obstacle and the operation of the button 352 becomes difficult. Therefore, as shown in FIG. 21, the button structure 350 is provided so as to overlap the outer peripheral edge 1001 of the intermediate mount 100 in the rotation axis direction of the intermediate mount 100.

Further, it is preferable that the thickness of the intermediate mount 100 and the mount module 300 in the optical axis direction is small so that the interchangeable lens 10 of the mount standard having a relatively short flange back can be mounted on the image pickup apparatus 500. Therefore, it is preferable that the thickness of the intermediate mount 100 and the mount module 300 in the optical axis direction does not increase due to the thickness of the button structure 350. Therefore, as shown in FIGS. 24 and 25, the button structure 350 is provided so as to overlap the outer peripheral surface 1002 of the button structure 350 in the radial direction of the intermediate mount 100. The button structure 350 is provided so that the push surface of the button 352 and the surface on the front surface side of the operating member 110 overlap each other in the radial direction of the intermediate mount 100.

By providing the button structure 350 in the mount module 300 in such an embodiment, it is possible to prevent the interchangeable lens 10 from becoming an obstacle and making it difficult to press the button 352. Further, the thickness of the intermediate mount 100 and the mount module 300 in the optical axis direction can be reduced.
