The camera mount 2 satisfies the predetermined mount standard, for example, the mount standard of a C mount, which is a type of screw mount. The camera mount 2 has a male screw 2X on the outer circumferential surface of the other open end 2B side (the other opening 2b side).

[0049] As shown in Figures 3 to 7 and Figure 10, the camera mount 2 is fixed (positioned) on the rotating body D (rotating main body 51). The camera mount 2 is positioned on the rotating body 51 (rotating body D) with one opening 2a (one opening end 2A / one cylinder end 2A) facing one opening 1a (opening end 1A) of the lens mount 1 in the direction of the mount centerline n (cylinder centerline) of the camera mount 2. The camera mount 2 is positioned concentrically with the mounting hole 69, with the mount centerline n of the camera mount 2 coinciding with the hole centerline β of the mounting hole 69.

[0050] As shown in Figures 6, 7, and 10, the camera mount 2 is fixed to the rotating support plate 68 by inserting (penetrating) its other open end 2B (cylindrical end) through the mounting hole 69 from the plate surface 68A of the rotating support plate 68. The camera mount 2 is fixed to the rotating support plate 68 by having one open end 2A (opening 2a) protruding from the plate surface 68A of the rotating support plate 68 between the mounts 1 and 2. The camera mount 2 is fixed to the rotating support plate 68 by having its other open end 2B protruding from the back surface 68 of the rotating support plate 68 between the rotating side plates 66 and 67. The camera mount 2 is fixed to the rotating support plate 68 (rotating body 51) with a mounting gap δ (the same gap as the mounting gap between the lens mount 1 and the plate surface 15A of the substrate 15) between the mount centerline n of the camera mount 2 and the plate surface 15A (reference plane) of the substrate 15.

[0051] As shown in Figures 5 and 7, each mount 1 and 2 is positioned with a gap between their open ends 1A and 2A (cylinder ends) in the direction M of the mount centerline m of the lens mount 1. The lens mount 1 and camera mount 2 are positioned at the same height from the reference plane (plate surface 15A) with the same mount height δ between the reference plane and the mount centerlines m and n of each mount 1 and 2.

[0052] As shown in Figures 3 to 5, the lens mount 1 (support B) is movable in the direction M of the mount centerline m of the lens mount 1 (the length direction J of the substrate 15). The lens mount 1 (support B) is movable (movable) relative to the substrate 15 (base A) in the direction M of the mount centerline m of the lens mount 1. The support B moves (moves) in the direction M of the mount centerline m of the lens mount 1 while the support bottom plate 21 (back surface 21B) slides (contacts) with the substrate 15 (front surface 15A).

[0053] In the guide body C, as shown in Figures 1, 2, 5, and 8, the bolts 35 and 36 are rotated in one direction relative to the respective fixing members 37 and 38, so that the heads 39 of each bolt 35 and 36 are separated from the support base plate 21 (plate surface 21A). As a result, the support body B and the lens mount 1 are made movable relative to the substrate 15 (base body A).

[0054] As shown in Figures 2, 5, and 8, the support body B is moved (movable) in the direction M of the mount centerline m of the lens mount 1 relative to the substrate 15 (base body A), while being guided by the screw shafts 40 (guide shafts) of each bolt 35, 36 and each guide slot 33, 34. The lens mount 1, which is fixed to the support body B (support plate 24), is moved (movable) in the direction M of the mount centerline m of the lens mount 1 (the length direction of the substrate 15) relative to the substrate 15 (base body A) as a result of the movement of the support body B. The guide body C guides (directs) the movement of the lens mount 1 (support body B).

[0055] The support B and lens mount 1 are moved (moved) relative to the substrate 15 (base A) rotating body D, and each mount 1, 2 By adjusting the distance between the two open ends 1A and 2A (open end faces), as shown in Figures 5 and 8, the bolts 35 and 36 of the guide body C are rotated in the opposite direction, pressing the heads 39 of the bolts 35 and 37 against the support base plate 21 (plate surface 21A), thereby fixing the support body B (lens mount 1) to the substrate 15 (base body A). As a result, the support B and the lens mount 1 are made immovable relative to the substrate 15 (base A).

[0056] As shown in Figures 5, 14, and 15, the rotating body D rotates the rotating main body 51 (camera mount 2) around a center line ρ (rotation center line) perpendicular to the mount center line m of the lens mount 1 (center line α of the mounting hole 25). The rotating body D rotates the rotating main body 51 (camera mount 2) around a center line ρ perpendicular to the mount center lines m and n of each mount 1 and 2 (center lines α and β of the mounting holes 25 and 69). The rotating body D rotates the camera mount 2 around the center line ρ, with one opening 2a (opening end 2A) of the camera mount 2 facing one opening 1a (opening end 1A) of the lens mount 1. The camera mount 2 and the rotating main body 51 are rotated relative to the substrate 15 (base A) around the center line ρ (rotation center line).

[0057] As shown in Figures 5, 9, and 15, the solid of revolution D has a center line ρ Using the center of rotation as the pivot point, the camera mount 2 is rotated (oscillated) relative to the substrate 15 (base A). In the rotating body D, each guide bolt 56, 57 is rotated in one direction relative to each fixing member 58, 59, so that the heads 75 of each guide bolt 56, 57 are separated from the rotating base plate 65 (plate surface 65A). As a result, the rotating body 51 and the camera mount 2 are made rotatable (oscillated) relative to the support B (lens mount 1) and the base A (substrate 15).

[0058] As shown in Figure 15, the rotating body D rotates (oscillates) the rotating body 51 (camera mount 2) within an angle θ range in one direction A (clockwise) from the mount centerline m of the lens mount 1 (centerline α of the mounting hole 25), with the centerline ρ as the center of rotation. The camera mount 2 and the rotating body 51 are rotated (oscillated) within an angle θ range in one direction A (clockwise) from the mount centerline m of the lens mount 1. The camera mount 2 is rotated within an angle θ range in one direction A, with one opening 2a of the camera mount 2 facing the one opening 1a of the lens mount 1.

[0059] As shown in Figure 15, the rotating body 51 rotates (oscillates) the camera mount 2 within an angle θ range in the other direction B (counterclockwise direction) from the mount center line m of the lens mount 1 (center line α of the mounting hole 25), with the center line ρ as the center of rotation. The camera mount 2 and the rotating body 51 are rotated (oscillated) within an angle θ range in the other direction B (counterclockwise direction) from the mount center line m of the lens mount 1. The camera mount 2 is rotated within an angle θ range in the other direction B, with one opening 2a of the camera mount 2 facing the one opening 1a of the lens mount 1. The rotating body D rotates the camera mount 2 within an angle 2θ range with the center line ρ as the center of rotation.

[0060] In the rotating body D, the rotating main body 51 is rotated (oscillated) relative to the base plate 15 (base body A) while being guided by the screw shafts 76 (guide shafts) of each guide bolt 56, 57 and the elongated shaft guide holes 54, 55, as shown in Figures 5, 9, and 15.

[0061] By rotating (oscillating) the camera mount 2 and the rotating body 51 relative to the substrate 15 (base A), the angle between the mount centerlines m and n of each mount 1 and 2 is adjusted. As shown in Figures 9 and 15, each guide bolt 56 and 57 is rotated in the opposite direction, pressing the heads 75 of each guide bolt 56 and 57 against the rotating base plate 65 (plate surface 21A), thereby fixing the rotating body 51 (camera mount 2) to the substrate 15 (base A). As a result, the rotating body 51 and the camera mount 2 are made unable to rotate relative to the substrate 15 (base A). The rotating body D prevents the camera mount 2 from rotating.

[0062] In the mounting device X1, the lens device Y is detachably attached to the lens mount 1, as shown in Figures 16, 17, 19, and 20.

[0063] As shown in Figures 16, 17, 19, and 20, the lens device Y (interchangeable lens) has a cylindrical lens body Y1 and a lens Y2 built into the lens body Y1. The lens device Y (interchangeable lens) is, for example, a lens mount 1, which is an F mount. (Registered trademark) The F-mount can be attached and detached freely. (Registered trademark) Lens device [ F-mount (Registered trademark) lens ] The lens device Y conforms to the mount standard of lens mount 1. [ F-mount (Registered Trademark) Lens device compatible with this device [ F-mount (Registered trademark) lens ] In the lens device Y, lens Y2 receives light from the subject and forms an image of the subject.

[0064] As shown in Figures 16, 17, and 19, the lens device Y (lens Y2) is positioned (coincided with) the optical axis λ of the lens device Y (lens Y2) on the mount centerline m of the lens mount 1 and is detachably mounted on the other open end 1B side (opening 1b side) of the lens mount 1. The lens device Y is attached to the other open end 1B side (support plate 24) of the lens mount 1 by inserting one cylindrical end of the lens body Y1 into the lens mount 1 from the other open end 1B side of the lens mount 1.

[0065] The lens device Y is removed by pulling out the other cylindrical end of the lens body Y1 from inside the lens mount 1 and detaching it from the lens mount 1 (the other open end 1B side of the lens mount 1).

[0066] As shown in Figure 19, a lens device Y is detachably mounted on the other open end 1B (opening 1b) of the lens mount 1. The lens device Y (lens Y2) is detachably mounted on the other open end 1B of the lens mount 1, with its optical axis λ positioned (coinciding) with the mount centerline m of the lens mount 1.

[0067] In the mounting device X1, a camera body Z (camera / imaging device) is detachably mounted on the camera mount 2, as shown in Figures 17 to 19. The camera body Z (camera) is, for example, the camera body of a C-mount camera that can be detachably mounted on the camera mount 2 (C-mount camera). The camera body Z is the camera body of a camera (C-mount camera) that is compatible with the mount standard (C-mount) of the camera mount 2.

[0068] As shown in Figures 17 to 19, the camera body Z includes a camera body portion Z1, an opening hole Za, a mount connecting portion Zb, and an image sensor S.

[0069] The camera body Z1 is shown in Figure 19. As shown, It has an internal space W (internal space).

[0070] The opening Za is formed in a circular shape (circular hole), as shown in Figure 19. The opening Za is formed in the camera body Z1. The opening Za penetrates the camera body Z1 and opens into the inside of the camera body Z (the space W of the camera body Z1).

[0071] The mount connecting portion Zb (mount connecting cylinder portion) is formed in a cylindrical shape, as shown in Figures 17 and 19. The mount connecting portion Zb is positioned concentrically with the opening hole Za and fixed to the camera body Z1. The mount connecting portion Zb protrudes from the camera body Z1. The mount connecting portion Zb has a female thread P on its inner circumferential surface.

[0072] As shown in Figures 17 to 19, the image sensor S is an image sensor that converts the image of a subject formed by the lens device Y (lens Y2) into a video signal. The image sensor S is located inside the camera body Z1 (the space of the camera body Z1). The image sensor S is located with its light-receiving surface Sa facing the aperture hole Za (inside the mount connecting part Zb). The image sensor S (light-receiving surface Sa) is exposed to the outside of the camera body Z1 through the aperture hole Za and the mount connecting part Zb. The image sensor S is located (coincides) with its center ω on the center line φ of the mount connecting part Zb (center line of the hole in the aperture hole Za). The image sensor S is located inside the camera body Z1 (the space W of the camera body Z1) with its light-receiving surface Sa perpendicular to the center line φ of the mount connecting part Zb (center line of the cylinder / center line of the hole in the aperture hole Za).

[0073] As shown in Figures 17 to 19, the camera body Z is detachably mounted on the other open end 2B (opening 2b side) of the camera mount 2, with the center ω of the image sensor S (the cylindrical center line φ of the mount connecting part Zb) positioned (coinciding) with the mount center line n of the camera mount 2. The camera body Z is detachably mounted on the other open end 2B side of the camera mount 2, with the light-receiving surface Sa of the image sensor S perpendicular to the mount center line n of the camera mount 2. The camera body Z is attached to the camera mount 2 by fitting the mount connecting part Zb onto the other open end 2B side of the camera mount 2 and screwing the female thread P of the mount connecting part Zb into the male thread 2X of the camera mount 2. The camera body Z is attached to the other open end 2B side of the camera mount 2 by rotating the camera body part Z1 in one direction relative to the camera mount 2 and screwing the male thread 2X of the camera mount 2 into the female thread P of the mount connecting part Zb. The camera body Z is detachably mounted on the other opening end 2B of the camera mount 2, with the center ω of the image sensor S positioned (coinciding) with the center line ρ (rotation center line) of the rotating body D. As shown in Figures 17 to 19, the image sensor S (light-receiving surface Sa) of the camera body Z is positioned on the optical axis λ of the lens device Y (lens Y2), facing one of the openings 1a of the lens mount 1, through the openings 2a, 2b and opening hole Za of the camera mount 2.

[0074] As shown in Figure 19, the camera body Z is removed from the camera mount 2 (the other open end 2B side of the camera mount 2) by rotating the camera body Z1 in the other direction, thereby disengaging the other open end 2B side of the camera mount 2 from the mount connecting part Zb.

[0075] As shown in Figures 17 to 19, the camera body Z is detachably mounted on the other open end 2B (opening 2b) of the camera mount 2. The camera body Z (image sensor S) is detachably mounted on the other open end 2B of the camera mount 2, with the light-receiving surface Sa of the image sensor S of the camera body Z perpendicular to the center line n of the camera mount 2. The camera body Z is detachably mounted on the other open end 2B of the camera mount 2, with the center ω of the image sensor S of the camera body Z positioned (coinciding) with the center line ρ (rotation center line) of the rotating body D.

[0076] Mounting device X1 (hereinafter referred to as "mounting device XQ"), which has a lens device Y mounted on lens mount 1 and a camera body Z mounted on camera mount 2, is positioned such that the light-receiving surface Sa of the image sensor S of the camera body Z [one of the aperture ends 2A (one of the aperture ends)] is parallel to the orthogonal plane SX [one of the aperture ends 1A (one of the aperture ends)] which is perpendicular to the mount centerline m of lens mount 1 (optical axis λ of lens device Y). In Figure 21, the focal plane is parallel to the principal lens surface of lens device Y (lens Y2) and the light-receiving surface Sa of image sensor S, respectively. The image sensor S (light-receiving surface Sa) of camera body Z is positioned perpendicular to the optical axis λ of lens device Y (lens Y2).

[0077] In Figures 20 and 22, the mounting device XQ rotates the camera mount 2 and camera body Z (image sensor S) from the state in Figure 21, as described in Figures 9 and 15, to tilt the light-receiving surface Sa of the image sensor S [one aperture end 2A of the camera mount 2 (one aperture end face)] at a tilt angle θa with respect to the orthogonal plane SX [one aperture end 1A of the lens mount 1 (one aperture end face)]. In the mounting device XQ, the rotating body D rotates (oscillates) the camera mount 2 and camera body Z (image sensor S) in one direction A or the other direction B from the mount center line m of the lens mount 1, with the center line ρ as the center of rotation, as described in Figures 9 and 15, to tilt the light-receiving surface Sa of the image sensor S at a tilt angle θa with respect to the orthogonal plane SX. The camera mount 2 and camera body Z (image sensor S) are rotated (oscillated) with one aperture 2a of the camera mount 2 facing one aperture 1a of the lens mount 1. The light-receiving surface Sa of the image sensor S of the camera body Z (one of the aperture end faces 2A of the camera mount 2) is tilted at an angle θa with respect to the orthogonal plane SX, and is positioned on the optical axis λ of the lens device Y (lens Y2) (on the mount centerline m of the lens mount 1) through the apertures 1a and 1b of each lens mount 1, the apertures 2a and 2b of the camera mount 2, and the aperture hole Za.

[0078] As shown in Figure 22, the mounting device X1 tilts the image sensor S of the camera body Z with respect to the orthogonal plane SX (the principal lens surface of the lens device Y), allowing it to focus on all subjects from near to far distances based on the Scheinproof principle. When the light-receiving surface Sa of the image sensor S is tilted with respect to the principal lens surface of the lens device Y, the focal plane is no longer parallel to the principal lens surface of the lens device Y and the light-receiving surface Sa of the image sensor S of the camera body Z, based on the Scheinproof principle, and the focal plane, the principal lens surface, and the light-receiving surface Sa of the image sensor S intersect on the same straight line. As a result, the camera body Z can focus on all subjects from near to far distances.

[0079] With the mount device X1, the lens device Y and camera body Z (image sensor) can be replaced by removing the lens device Y from the lens mount, removing the camera body Z from the camera mount 2, attaching another lens device Y to the lens mount 1, and attaching another camera body Z to the camera mount 2.

[0080] In the mount device X1, the lens device Y is removed from the lens mount 1 and the mount standard of the lens mount 1 is changed. [ F-mount (Registered Trademark) Various lens devices Y compatible with [ F-mount (Registered trademark) lens ] By attaching it to lens mount 1, the mount standard of lens mount 1 [ F-mount (Registered Trademark) Lens device Y corresponding to [ F-mount (Registered trademark) lens ] It can be replaced. With the mounting device X1, the camera body Z can be removed from the camera mount 2, and various camera bodies Z (camera bodies of C-mount cameras) that are compatible with the mount standard (C-mount) of the camera mount 2 can be attached to the camera mount 2, thereby replacing the camera body Z with a camera body Z of a camera (C-mount camera) that is compatible with the mount standard (C-mount) of the camera mount 2.
