[0047] As shown in FIGS. 1, 2, 5, and 7, the lens mount 1 is fixed to the support plate 24 by inserting one opening end 1A (opening 1a) into (penetrating) a mounting hole 25 from a plate surface 24A of the support plate 24. The lens mount 1 is fixed (placed) on the support plate 24 with one opening end 1A (opening 1a side) protruding from a plate back surface 24B of the support plate 24 toward the rotating body 51 (rotating body D). The lens mount 1 is fixed to the support plate 24 with the other opening end 1B (opening 1b side) protruding from the plate surface 24A of the support plate 24 toward one plate length end side of the support bottom plate 21 (one plate length 15c side of the substrate 15). The lens mount 1 is fixed to the support plate 24 with a mount distance δ (mount height) between the mount center line m of the lens mount 1 and the plate surface 15A (reference plane) of the substrate 15.

[0048] As shown in Figures 3 to 7 and 10, the camera mount 2 is formed in a cylindrical shape. The camera mount 2 is a mount that complies with a predetermined mount standard. 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 thread 2X on the outer circumferential surface on the other opening end 2B side (the other opening 2b side).

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

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

[0051] 5 and 7, the mounts 1 and 2 are arranged at a distance between one open end 1A and one open end 2A (cylinder end) of each mount 1 and 2 in the direction M of the mount center line m of the lens mount 1. The lens mount 1 and the camera mount 2 are arranged at the same height from the reference plane (plate surface 15A), with the same mount height δ between the reference plane and the mount center lines m and n of each mount 1 and 2.

[0052] 3 to 5, the lens mount 1 (support body B) is movable in the direction M of the mount center line m of the lens mount 1 (the plate length direction J of the substrate 15). The lens mount 1 (support body B) is movable (movable) relative to the substrate 15 (base A) in the direction M of the mount center line m of the lens mount 1. The support body B is moved (movable) in the direction M of the mount center line m of the lens mount 1 while the support bottom plate 21 (plate rear surface 21B) is in sliding contact (abutment) with the substrate 15 (plate surface 15A) in the direction M of the mount center line m of the lens mount 1.

[0053] In the guide body C, as shown in FIGS. 1, 2, 5 and 8, the bolts 35, 36 are rotated in one direction relative to the fixing members 37, 38 to move the heads 39 of the bolts 35, 36 away from the support bottom plate 21 (plate surface 21A). This allows the support body B and the lens mount 1 to be movable relative to the substrate 15 (base body A).

[0054] 2, 5, and 8, the support body B is moved (movable) in the direction M of the mount center line 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 the bolts 35, 36 and the elongated guide holes 33, 34. The lens mount 1 fixed to the support body B (support plate 24) is moved (movable) in the direction M of the mount center line m of the lens mount 1 (the plate length direction J of the substrate 15) relative to the substrate 15 (base body A) by the movement of the support body B. The guide body C guides the movement of the lens mount 1 (support body B).

[0055] When the support body B and the lens mount 1 are moved (moved) relative to the substrate 15 (base A) rotor D to adjust the distance between one of the opening ends 1A, 2A (opening end faces) of each mount 1, 3, as shown in Figures 5 and 8, the bolts 35, 36 of the guide body C are rotated in the other direction, and the heads 39 of the bolts 35, 37 are pressed against the support bottom plate 21 (plate surface 21A), thereby fixing the support body B (lens mount 1) to the substrate 15 (base A). This makes the support B and the lens mount 1 immovable relative to the substrate 15 (base A).

[0056] As shown in FIGS. 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) that is perpendicular to the mount center line m (hole center line α of the mounting hole 25) of the lens mount 1. The rotating body D rotates the rotating main body 51 (camera mount 2) around a center line ρ that is perpendicular to the mount center lines m and n (hole center lines α and β of the mounting holes 25 and 69) of the mounts 1 and 2. The rotating body D rotates the camera mount 2 around the center line ρ while facing one opening 2a (opening end 2A) of the camera mount 2 to one opening 1a (opening end 1A) of the lens mount 1. The camera mount 2 and the rotating main body 51 rotate with respect to the substrate 15 (base A) around the center line ρ (rotation center line).

[0057] As shown in Figures 5, 9, and 15, the rotating body D rotates (swings) the camera mount 2 relative to the substrate 15 (base body A) around the center line 42ρ. In the rotating body D, the guide bolts 56, 57 are rotated in one direction relative to the fixing members 58, 59, and the heads 75 of the guide bolts 56, 57 are moved away from the rotating bottom plate 65 (plate surface 65A). This allows the rotating main body 51 and the camera mount 2 to rotate (swing) freely relative to the support body B (lens mount 1) and base body A (substrate 15).

[0058] As shown in Fig. 15, the rotating body D rotates (swings) the rotating body 51 (camera mount 2) around the center line ρ as the center of rotation in one direction A (clockwise direction) from the mount center line m of the lens mount 1 (the hole center line α of the mounting hole 25) within a range of angle θ. The camera mount 2 and the rotating body 51 are rotated (swings) in one direction A (clockwise direction) from the mount center line m of the lens mount 1 within a range of angle θ. The camera mount 2 is rotated in one direction A within a range of angle θ while one opening 2a of the camera mount 2 faces one opening 1a of the lens mount 1.

[0059] As shown in FIG. 15 , the rotating body 51 rotates (swings) the rotating body 51 (camera mount 2) around the center line ρ, within a range of angle θ in the other direction B (counterclockwise direction) from the mount center line m of the lens mount 1 (the hole center line α of the mounting hole 25). The camera mount 2 and the rotating body 51 rotate (swing) around the center line ρ, within a range of angle θ, in the other direction B (counterclockwise direction) from the mount center line m of the lens mount 1. The camera mount 2 rotates around the center line ρ, within a range of angle θ, in the other direction B, with one opening 2a of the camera mount 2 facing one opening 1a of the lens mount 1. The rotating body D rotates the camera mount 2 around the center line ρ, within a range of angle 2θ.

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

[0061] When the camera mount 2 and the rotating body 51 are rotated (swinged) relative to the substrate 15 (base A) and the angle between the mount center lines 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 other direction, and the heads 75 of each guide bolt 56 and 57 are pressed against the rotating bottom plate 65 (plate surface 21A), fixing the rotating body 51 (camera mount 2) to the substrate 15 (base A). This makes it impossible for the rotating body 51 and the camera mount 2 to rotate relative to the substrate 15 (base body A). The rotating body D makes it impossible for the camera mount 2 to rotate.

[0062] In the mount device X1, a lens device Y is detachably attached to the lens mount 1, as shown in FIGS.

[0063] As shown in Figures 16, 17, 19, and 20, the lens device Y (interchangeable lens) has a cylindrical (tubular) lens body Y1 and a lens Y2 built into the lens body Y1. The lens device Y (interchangeable lens) is, for example, an F-mount lens device (F-mount lens) that can be detachably attached to an F-mount, which is a lens mount 1. The lens device Y is a lens device (F-mount lens) that complies with the mount standard (F-mount) of the lens mount 1. In the lens device Y, the lens Y2 inputs light from a subject and forms an image of the subject.

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

[0065] The lens device Y is removed from the lens mount 1 (the other open end 1B side of the lens mount 1) by extracting the other barrel end side of the lens body Y1 from inside the lens mount 1.

[0066] 19, a lens device Y is detachably attached to the other opening end 1B side (opening 1b side) of the lens mount 1. The lens device Y (lens Y2) is detachably attached to the other opening end 1B side of the lens mount 1 with the optical axis λ of the lens device Y (lens Y2) positioned (aligned) with the mount center line m of the lens mount 1.

[0067] 17 to 19, in mount device X1, camera body Z (camera / imaging device) is detachably attached to camera mount 2. Camera body Z (camera) is, for example, the camera body of a C-mount camera (C-mount camera) that can be detachably attached to a C-mount in camera mount 2. Camera body Z is the camera body of a camera (C-mount camera) that complies with the mount standard (C-mount) of camera mount 2.

[0068] The camera body Z has a camera body portion Z1, an opening hole Za, a mount connection portion Zb, and an imaging element S, as shown in FIGS.

[0069] The camera body Z1 has a space W (internal space) inside as shown in FIG.

[0070] The opening Za is formed in a circular shape (circular hole) as shown in Fig. 19. The opening Za is formed in the camera body Z1. The opening Za penetrates the camera body Z1 and opens into the interior 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 arranged concentrically with the opening hole Za and is fixed to the camera body portion Z1. The mount connecting portion Zb is arranged to protrude from the camera body portion Z1. The mount connecting portion Zb has a female thread P on its inner circumferential surface.

[0072] As shown in FIGS. 17 to 19, the imaging element S is an image sensor that converts an image of a subject formed by the lens device Y (lens Y2) into a video signal. The imaging element S is disposed within the camera body Z1 (the space within the camera body Z1). The imaging element S is disposed with its light-receiving surface Sa facing the aperture hole Za (inside the mount connection portion Zb). The imaging element S (light-receiving surface Sa) is exposed to the outside of the camera body Z1 through the aperture hole Za and the mount connection portion Zb. The imaging element S is disposed with its center ω aligned with (coinciding with) the center line φ (center line of the aperture hole Za) of the mount connection portion Zb. The imaging element S is disposed within the camera body Z1 (the space W within the camera body Z1) with its light-receiving surface Sa perpendicular to the center line φ (center line of the barrel / center line φ of the aperture hole Za) of the mount connection portion Zb.

[0073] As shown in FIGS. 17 to 19 , the camera body Z is detachably attached to the other opening end 2B side (opening 2b side) of the camera mount 2 with the center ω (cylinder center line φ of the mount connecting portion Zb) of the image sensor S positioned (aligned) with the mount center line n of the camera mount 2. The camera body Z is detachably attached to the other opening 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 portion Zb onto the other opening end 2B side of the camera mount 2 and threading the female thread P of the mount connecting portion Zb into the male thread 2X of the camera mount 2. The camera body Z is attached to the other opening end 2B side of the camera mount 2 by rotating the camera body Z1 in one direction relative to the camera mount 2 and threading the male thread 2X of the camera mount 2 into the female thread P of the mount connecting portion Zb. The camera body Z is detachably mounted on the other opening end 2B side of the camera mount 2, with the center ω of the image sensor S positioned (aligned) 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 faces one opening 1a of the lens mount 1 through the openings 2a, 2b and opening hole Za of the camera mount 2, and is installed on the optical axis λ of the lens device Y (lens Y2).

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

[0075] 17 to 19, camera body Z is detachably attached to the other opening end 2B side (opening 2b side) of camera mount 2. Camera body Z (imaging element S) is detachably attached to the other opening end 2B side of camera mount 2 with the light receiving surface Sa of the imaging element S of camera body Z perpendicular to the mount center line n of camera mount 2. Camera body Z is detachably attached to the other opening end 2B side of camera mount 2 with the center ω of the imaging element S of camera body Z positioned (aligned) with the center line ρ (rotation center line) of the rotating body D.

[0076] 16 to 19 and 21, a mount device X1 (hereinafter referred to as "mount device XQ") having a lens device Y mounted on a lens mount 1 and a camera body Z mounted on a camera mount 2 is arranged so that the light receiving surface Sa of the image sensor S of the camera body Z [one of the opening ends 2A (one of the opening end faces) of the camera mount 2] is parallel to an orthogonal plane SX [one of the opening ends 1A (one of the opening end faces) of the lens mount 1] that is perpendicular to the mount center line m of the lens mount 1 (the optical axis λ of the lens device Y). In FIG. 21, the focal plane is parallel to both the lens principal surface of the lens device Y (lens Y2) and the light receiving surface Sa of the image sensor S. The image sensor S (light receiving surface Sa) of the camera body Z is arranged perpendicular to the optical axis λ of the lens device Y (lens Y2).

[0077] 20 and 22, the mount device XQ rotates the camera mount 2 and camera body Z (image sensor S) from the state shown in FIG. 21, as described with reference to FIGS. 9 and 15, to tilt the light receiving surface Sa of the image sensor S [one opening end 2A (one opening end surface) of the camera mount 2] at a tilt angle θa relative to the orthogonal plane SX [one opening end 1A (one opening end surface) of the lens mount 1)]. In the mount device XQ, the rotator D rotates (swings) 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, to tilt the light receiving surface Sa of the image sensor S at a tilt angle θa relative to the orthogonal plane SX. The camera mount 2 and camera body Z (image sensor S) are rotated (swings) while one opening 2a of the camera mount 2 faces one opening 1a of the lens mount 1. The light receiving surface Sa (one of the opening end surfaces 2A of the camera mount 2) of the image sensor S of the camera body Z is inclined at a tilt angle θa with respect to the perpendicular plane SX, and is placed on the optical axis λ of the lens device Y (lens Y2) (on the mount center line m of the lens mount 1) through each opening 1a, 1b of each lens mount 1, each opening 2a, 2b of the camera mount 2, and the opening hole Za.

[0078] As shown in Fig. 22, mount device X1 tilts image sensor S of camera body Z relative to the orthogonal plane SX (lens principal surface of lens device Y), and is therefore able to focus on all subjects from close distances to long distances based on the Scheimpflug principle. When the light receiving surface Sa of image sensor S is tilted relative to the lens principal surface of lens device Y, the focal plane is no longer parallel to the lens principal surface of lens device Y and the light receiving surface Sa of image sensor S of camera body Z based on the Scheimpflug principle, and the focal plane, lens principal surface, and light receiving surface Sa of image sensor S intersect on the same straight line. This allows camera body Z to focus on all subjects from close distances to long distances.

[0079] In the mount device X1, the lens device Y and the 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, and then attaching another lens device Y to the lens mount 1 and another camera body Z to the camera mount 2.

[0080] In mount device X1, lens device Y can be replaced with a lens device Y (F-mount lens) that is compatible with the mount standard (F-mount) of lens mount 1 by removing lens device Y from lens mount 1 and attaching various lens device Y (F-mount lens) that is compatible with the mount standard (F-mount) of lens mount 1 to lens mount 1. In mount device X1, camera body Z can be replaced with a camera body Z of a camera (C-mount camera) that is compatible with the mount standard (C-mount) of camera mount 2 by removing camera body Z from camera mount 2 and attaching various camera body Z (camera body of a C-mount camera) that is compatible with the mount standard (C-mount) of camera mount 2 to camera mount 2. [Industrial Applicability]

[0081] The present invention is ideal for interchangeably mounting lens devices and camera bodies. [Explanation of symbols]
