  The present invention relates to a support device and a microscope including the support device.

  Conventionally, a stand device for magnifying observation to which a camera is attached has been developed (for example, see Patent Document 1).

  Here, an outline of the conventional stand device will be described with reference to the drawings.

  FIG. 11 is a side view showing a conventional stand device for magnified observation, and FIG. 12 is a front view showing a conventional stand device for magnified observation.

  As shown in FIG. 11, a conventional stand device for magnification observation (hereinafter simply referred to as a stand device) includes a fixed column 120 and a fixed column 130. The fixed column 120 and the fixed column 130 are each erected on the base 140.

  A rotating column 110 is attached to the upper end portion of the fixed column 130 via a rotating mechanism 130A.

  A camera mounting portion 111 is attached to the rotating column 110. A camera C for magnifying observation is attached to the camera attachment portion 111.

  In addition, a stage 126 for mounting the measurement object W is attached to the fixed support 120 via the stage attachment part 121. The stage 126 is composed of an XY stage that can move in the X-axis direction and the Y-axis direction constituting a plane, and is fixed on the stage mounting portion 121 by a set screw 125. Note that an enlarged image of the measurement object W captured by the camera C is displayed on a display such as a liquid crystal display.

  The rotating mechanism 130A supports the rotating column 110 about the horizontal axis H in a rotatable manner.

  The rotation mechanism 130 </ b> A includes a cylindrical bearing 131, a rotation shaft 132, and a set screw knob 133. When the rotation shaft 132 is fitted to the cylindrical bearing 131, the rotation shaft 132 rotates around the horizontal axis H.

  Further, the set screw knob 133 is provided so as to penetrate the cylindrical bearing 131, and unnecessary rotation of the rotary shaft 132 is prevented by bringing the set screw knob 133 into contact with the rotary shaft 132. ing.

  That is, as shown by a one-dot chain line in FIG. 12, the rotating support column 110 is provided so that the inclination angle A with respect to the vertical line V can be freely adjusted.

  The rotary support 110 is provided with a coarse adjustment mechanism 150A (FIG. 11) and a fine adjustment mechanism 160A, and the fixed support 120 is provided with a coarse adjustment mechanism 150B and a fine adjustment mechanism 160B. With such a configuration, the camera mounting portion 111 and the stage 126 are coarsely moved and finely adjusted in the direction of the vertical line V (up and down direction) with respect to the rotating support column 110 and the fixed support column 120, respectively.

  Here, the details of the coarse movement mechanisms 150A and 150B and the fine adjustment mechanisms 160A and 160B will be described.

  As shown in FIG. 11, coarse movement mechanisms 150A and 150B are respectively provided with sliders 112 and 122 slidably provided on a rotating support column 110 and a fixed supporting column 120, and these sliders 112 and 122 are fixed to the rotating support column 110 and fixed.

  However, in the conventional stand device, when the camera C is mounted on the camera mounting portion 111 so that the visual field center I1 of the camera C and the rotation center I2 of the rotation column 110 are shifted, the following problems occur. Arise.

  That is, when the rotation support 110 is tilted with reference to the rotation center, the observation point and the focus of the measurement object W observed without tilting the rotation support 110 are shifted. Therefore, in the conventional stand device, the observation point and the focus must be corrected by moving the stage mounting portion 121 up and down each time the inclination angle A of the rotating support column 110 is changed, which is very troublesome. Take it. In particular, when the camera C with a high magnification (for example, 100 to 500 times) is used, the amount of deviation of the observation point becomes significant.

  An object of the present invention is to provide a support device capable of easily making the optical axis (center of field of view) of an image pickup means and the rotation axis (rotation center) of a support member supporting the image pickup means orthogonal to each other and a microscope equipped with the support device Is to provide.

A stand device for magnification observation according to a first aspect of the present invention is a stand device for magnification observation to which an imaging means for imaging a measurement object is attached in order to enlarge and observe the measurement object. A stage having a mounting surface to be placed; an attachment means to which the imaging means is attached so that the optical axis faces the stage; a support member that supports the attachment means; and a support member that is provided on the support member and is integrated with the support member A rotating shaft that rotates about a horizontal axis, a holding means that rotatably holds the rotating shaft, a support base that supports the holding means, a base to which the support base is attached, a stage below and on the base And a height adjustment mechanism that can adjust the height of the stage so that the height of the surface of the measurement object placed on the stage matches the height of the rotation center of the support member. Means imaging As the optical axis of the stage is perpendicular to the pivot axis, which has an adjustment means for adjusting the relative horizontal position of the imaging means relative to the support member while the optical axis of the imaging means is perpendicular to the mounting surface of the stage is there.

In the support device according to the present invention, the measurement object is placed on the placement surface of the stage. The imaging means is attached to the attachment means so that the optical axis faces the stage, and this attachment means is supported by the support member. The support member is held by the holding means so as to be inclined within a predetermined plane around the rotation axis. The relative horizontal position of the imaging means is supported by the adjusting means of the attachment means while the optical axis of the imaging means is orthogonal to the stage mounting surface so that the optical axis of the imaging means is orthogonal to the rotation axis. It is adjusted relative to the member.

In such a configuration, by using the adjustment means, it can be easily perpendicular to the optical axis of rotating shaft and the imaging means. Thereby, even when the measurement object is observed from an oblique direction by tilting the rotating member, the observation point on the measurement object and the desired observation point can be observed in a focused state without shifting the focus. it can. In particular, when a high-magnification image pickup unit is used, the above-described effects are prominent.

The stage may be provided so as to be rotatable around a rotation axis perpendicular to the mounting surface, and the stage and the holding means may be arranged so that the rotation axis of the stage and the rotation axis are orthogonal to each other.

Thus, by arranging the stage and the holding means so that the rotation axis and the rotation axis of the stage are orthogonal to each other, the operator can take an image by matching the rotation axis of the stage and the optical axis of the imaging means. The optical axis of the means and the rotation axis can be made to be orthogonal to each other. In this case, the operator can easily match the rotation axis of the stage and the optical axis of the imaging means by observing the image obtained by the imaging means while rotating the stage.

The adjusting means moves the imaging means in first and second axis directions orthogonal to the optical axis of the imaging means in order to adjust the relative horizontal position of the imaging means with respect to the support member. The adjusting means includes an attaching member having a hole, and an annular tool provided in the hole so as to be movable in a plane including the first and second shafts and through which the imaging means is inserted; The first and second adjusting means may include first and second adjusting members that are in contact with the outer peripheral surface of the annular tool and are movable in the directions of the first and second axes, respectively.

In this case, the imaging unit is moved in the directions of the first and second axes orthogonal to the optical axis of the imaging unit by the first and second adjustment units. By pressing the outer peripheral surface of the annular tool through which the imaging means is inserted with the first and second adjustment members, the imaging means can be moved indirectly in the directions of the first and second axes. Since the imaging means is not in direct contact with the first and second adjustment members, the operator can easily replace the imaging means by removing the imaging means from the annular tool and inserting the imaging means into the annular tool. Can be done quickly.

  The attaching means may further include an urging means for urging the outer peripheral surface of the annular tool so as to face the substantially center of the annular tool.

  In this case, the annular tool is pressed against the tips of the first and second adjustment members by the biasing means. Thereby, it is prevented that an annular tool is moved too much by operation of the 1st and 2nd adjustment member by an operator. As a result, it is possible to accurately adjust the position of the annular tool while the tips of the first and second adjustment members are always in contact with the annular tool.

  The attachment means may further include a fixture that fixes the annular tool together with the first and second adjustment members by contacting the portion of the annular tool that is biased by the biasing means.

  In this case, the position of the annular tool in the hole is reliably fixed by the fixing tool together with the first and second adjusting members.

  The support device may further include a cable restraining unit that is provided in the holding unit and restrains a cable connected to the imaging unit.

  In this case, since the cable is restrained by the cable restraining means, even if the imaging means to which the cable is connected is tilted with the inclination of the support member, rattling at the connection portion between the imaging means and the cable is prevented. It is possible to prevent the cable from being forcibly pulled due to the inclination of the image pickup means. Thereby, even when the imaging unit is tilted and the measurement object is observed, the position of the imaging unit can be stabilized.

  The attachment means has a hole, the support member includes a rod-like member that is movably inserted into the hole of the attachment means, and the attachment means is made into a rod-like member in a state where the rod-like member is inserted into the hole of the attachment means. Coarse movement means is further provided, the coarse movement means has a wedge-shaped tip, the rod-like member has a long groove extending in the axial direction, and the tip of the coarse movement means is fitted into the long groove of the rod-like member. May be.

  In this case, when fixing the attachment means to the rod-shaped member, the operator operates the coarse movement means. Thus, the wedge-shaped tip portion of the pole fixing knob that is the coarse movement means is firmly fitted in the long groove formed in the rod-shaped member. Thereby, the attachment means is fixed in a state of being accurately positioned with respect to the coarse movement means.

  Further, since the long groove has a predetermined length along the length direction of the rod-shaped member, the operator slides the mounting means up and down within a predetermined range, and coarsely moves at a desired height position. The fitting means can be fixed at a desired position of the rod-shaped member by fitting the tip of the means into the long groove.

  The rod-shaped member may include a plurality of scale portions indicating a plurality of positions in the axial direction.

  In this case, the plurality of positions can indicate, for example, the model number or product name of the imaging means being used. With such a configuration, the operator can easily adjust the fixing position of the attaching means with respect to the rod-shaped member to the position of the model number or product name of the imaging means being used. Thereby, the distance between the tip of the imaging means and the stage is appropriately set according to the type of the imaging means.

The imaging means is attached to the attachment means so that the optical axis faces the stage, and this attachment means is supported by the support member. The support member is held by the holding means so as to be inclined within a predetermined plane around the rotation axis. The relative horizontal position of the imaging means is supported by the adjusting means of the attachment means while the optical axis of the imaging means is orthogonal to the stage mounting surface so that the optical axis of the imaging means is orthogonal to the rotation axis. It is adjusted relative to the member.

In such a configuration, by using the adjustment means, it can be easily perpendicular to the optical axis of rotating shaft and the imaging means. Thereby, even when the measurement object is observed from an oblique direction by tilting the rotating member, the observation point on the measurement object and the desired observation point can be observed in a focused state without shifting the focus. it can. In particular, when a high-magnification image pickup unit is used, the above-described effects are prominent.

  A thin adapter 95 formed in a ring shape is provided in the hole 91b. The adapter 95 is attached to a fixing screw 92 screwed into the side surface of the camera attachment portion 9.

  Further, an X-axis adjustment screw 93a and a Y-axis adjustment screw 93b are threadedly engaged with the side surface of the camera attachment portion 9 along the X-axis direction and the Y-axis direction. That is, the X-axis adjustment screw 93 a and the Y-axis adjustment screw 93 b are screwed together so as to go toward the center of the adapter 95. The movement amount of the X-axis adjustment screw 93a and the Y-axis adjustment screw 93b is 2 mm, for example.

  The X-axis adjusting screw 93a and the Y-axis adjusting screw 93b press the outer peripheral surface of the adapter 95 in the X-axis direction and the Y-axis direction, respectively. The operator rotates the X-axis adjustment screw 93a and the Y-axis adjustment screw 93b so that the tip ends of the X-axis adjustment screw 93a and the Y-axis adjustment screw 93b come into contact with the outer peripheral surface of the adapter 95. Thereby, the adapter 95 is moved in the X-axis direction and the Y-axis direction.

  The camera 10 is inserted through the adapter 95 along the Z-axis direction so as to contact the inner peripheral surface of the adapter 95.

  With such a configuration, in the present embodiment, the outer surface of the adapter 95 through which the camera 10 is inserted is pressed by the X-axis adjusting screw 93a and the Y-axis adjusting screw 93b, thereby moving the camera 10 in the X-axis direction and the Y-axis. It is moved indirectly in the axial direction. Thereby, the operator can easily and quickly replace the camera 10.

  In FIG. 4, when the positions where the X-axis adjusting screw 93a and the Y-axis adjusting screw 93b are in contact with the outer peripheral surface of the adapter 95 are two vertices of the three vertices constituting the triangle, the remaining one A fixture 94 is provided so as to contact the position of the outer peripheral surface of the adapter 95 corresponding to the position of the apex.

  The abutment of the outer peripheral surface of the adapter 95 by the fixture 94 is performed via a leaf spring 96. The leaf spring 96 has a U-shaped cross section, and has a flat surface portion 96a and a flat surface portion 96b facing the flat surface portion 96a.

  The flat portion 96b of the leaf spring 96 is fixed by a set screw 97, and the flat portion 96a is in contact with the outer peripheral surface of the adapter 95 and urges the outer peripheral surface. Thereby, the adapter 95 is pressed against the tips of the X-axis adjustment screw 93a and the Y-axis adjustment screw 93b.

  The operator can adjust the position of the adapter 95 by turning the X-axis adjusting screw 93a and the Y-axis adjusting screw 93b.

  The fixture 94 includes a fixture contact portion 94a that is screwed to the side surface of the camera attachment portion 9 and a fixture knob portion 94b that is attached to the fixture contact portion 94a. The fixture contact portion 94 a contacts the flat portion 96 a of the leaf spring 96.

  When the fixture knob portion 94b is turned by an operator, the rotational force is transmitted to the fixture contact portion 94a.

  Here, the fixture knob portion 94b has a mechanism (clutch mechanism) that idles with a predetermined torque. In this case, when the operator turns the fixture knob portion 94b excessively and the rotational force (driving force) reaches a predetermined torque, no further rotational force is transmitted to the fixture contact portion 94a. With such a configuration, even when the operator excessively operates the fixture knob portion 94, it is possible to prevent excessive pressing against the flat portion 96a of the leaf spring 96 by the fixture contact portion 94a. Thereby, the camera 10 can be easily positioned.

  Next, a method of tilting the rotating column 5 of the microscope 100 will be described with reference to the drawings.

  Moreover, the rotation lock unlocking member 30 has the slit part 30b connected to the said hole part 30a. In addition, this slit part 30b is formed along the Z-axis direction, and has a width of 1 to 2 mm, for example.

  A slit knob 32 is screwed to one side surface of the rotation lock unlocking member 30, and the slit knob 32 is screwed to the other side surface through the slit portion 30b.

  In such a configuration, when the operator turns the slit knob 32, the slit knob 32 advances in the direction of the arrow L in FIG. Thereby, the width of the slit portion 30b is narrowed, so that the circumferential length of the hole portion 30a communicating with the slit portion 30b is reduced. Thereby, the rotation of the rotation shaft 31 fitted to the connecting portion 4 is restrained, and the rotation of the rotation column 5 is prevented.

  Conversely, when the operator turns the slit knob 32 in the opposite direction, the slit knob 32 advances in the direction opposite to the arrow L. Thereby, when the width of the slit portion 30b is expanded, the circumferential length of the hole portion 30a communicating with the slit portion is increased. Thereby, the restraint of the rotating shaft 31 fitted to the connecting portion 4 is released, and the rotating support column 5 can be rotated.

  Next, a method for rotating (inclining) the rotating column 5 by the operator will be described with reference to FIGS. 5 and 6.

  In FIG. 5, the end surface of the rotation shaft 31 is provided with a hook portion 31 a which is formed in a columnar shape and whose central axis is coaxial with the central axis of the rotation shaft 31. A long hole 33a of the lever 33 is fitted in the hook portion 31a. In addition, a rotation contact pin 31b is provided at the peripheral edge of the end surface of the rotation shaft 31 perpendicularly to the end surface. Hereinafter, the configuration of the lever 33 will be described.

  The lever 33 includes a first rotation restricting portion 33b that prevents the rotation of the rotation contact pin 31b that rotates counterclockwise with the rotation of the rotation shaft 31 at a predetermined angle, and the rotation shaft. A second rotation restricting portion 33c that prevents the rotation of the rotation contact pin 31b that rotates clockwise with the rotation of the rotation angle 31 at a predetermined angle. The predetermined angle is an angle with respect to the Z-axis direction as a reference (0 °).

  In the configuration as described above, when the operator tilts the rotation column 5 counterclockwise by, for example, 90 °, the rotation contact pin 31 b is moved to the second position of the lever 33 along with the rotation of the rotation shaft 31. By abutting against one rotation restricting portion 33b, the rotation support column 5 is not inclined counterclockwise at an angle exceeding 90 °.

  In addition, as shown in FIG. 6, when the operator tilts the rotation column 5 clockwise by, for example, 60 °, the rotation contact pin 31 b moves to the lever 33 as the rotation shaft 31 rotates. By contacting the second rotation restricting portion 33c, the rotation support column 5 is not inclined clockwise at an angle exceeding 60 °.

  With such a configuration, the operator can tilt the rotating column 5 within a range of a predetermined angle, and the rotating camera 5 is inadvertently inclined, so that the expensive camera 10 is placed on the stage S. Collision and damage are prevented.

  Here, in this embodiment, the lever 33 can be used to incline the rotary support column 5 at an angle exceeding 90 ° counterclockwise. Hereinafter, this method will be described.

  FIG. 7 is a schematic view showing a state in which the rotating support column 5 is tilted counterclockwise at an angle exceeding 90 ° using the lever 33. Note that the microscope 100 in FIG. 7 is illustrated with some of them omitted, and the internal configuration of the second guide portion 3b of the bearing portion 3a is shown.

  As shown in FIG. 7, one end of the spring SP is attached to one end of the lever 33. The other end of the spring SP is fixed to the rotation lock unlocking member 30. The lever 33 is urged by the spring SP in the direction of the arrow L in a normal state.

  The other end portion of the lever 33 is provided so as to protrude outward from the inside of the second guide portion 3b of the bearing portion 3a.

  When the lever 33 is pulled in the direction opposite to the arrow L by the operator, the position of the fitting of the elongated hole 33a of the lever 33 with respect to the hanging portion 31a moves, so that the lever 33 moves in the direction opposite to the arrow L. Moving.

  In this case, since the first rotation restricting portion 33b of the lever 33 is moved in the direction opposite to the arrow L, the operator tilts the rotation column 5 counterclockwise to an angle exceeding 90 °. In addition, the rotation contact pin 31b that rotates counterclockwise as the rotation column 5 rotates does not contact the first rotation restriction portion 33b. Thereby, the operator can incline the rotation support | pillar 5 to the angle exceeding 90 degrees counterclockwise.

  As described above, even when the rotating support column 5 is inclined counterclockwise to an angle exceeding 90 °, the rotating support column 5 is not further inclined more than a predetermined angle. This will be described below.

  FIG. 8 is a schematic diagram showing a state in which the rotating support column 5 is tilted counterclockwise as much as possible.

  As shown in FIG. 8, the back cover 2a is provided so that the back surface of the 1st support stand 2 and the bearing part 3a may be covered. In addition, said back surface means the surface on the opposite side to the surface by the side of the stage S of the 1st support stand 2 and the bearing part 3a.

  In the present embodiment, the cover 2a has an arcuate hole along the locus of the rotating contact pin 31b that rotates clockwise and counterclockwise as the rotating column 5 rotates. 2b is provided.

  A rotation contact pin 31b is provided so as to protrude outward from the hole 2b of the cover 2a.

  The hole portion 2a rotates with one end portion 2c with which the rotation contact pin 31b contacts at the position of 120 ° when the rotation contact pin 31b is inclined, for example, 120 ° counterclockwise. When the contact pin 31b is inclined, for example, 70 ° clockwise, the rotation contact pin 31b has the other end 2d that contacts at the 70 ° position.

  In such a configuration, the rotation contact pin 31b contacts the one end 2c and the other end 2d of the hole 2a at the 120 ° position and the 70 ° position, respectively. The moving column 5 is not inclined counterclockwise toward an angle exceeding 120 °, and is not inclined clockwise toward an angle exceeding 70 °. Thereby, safety and protection of the camera 10 are improved. Note that the above 120 ° and 70 ° are merely examples, and the present invention is not limited thereto. The 120 ° may be 110 °, for example, and the 70 ° may be 75 °, for example.

  Next, the detailed structure of the bearing part 3a in this Embodiment and the attachment method of the connection part 4 with respect to this bearing part 3a are demonstrated.

  FIG. 9 is a schematic view showing a state before the bearing portion 3 a, the rotating shaft 31 and the connecting portion 4 are assembled. FIG. 10A shows the bearing portion 3 a via the rotating shaft 31. FIG. 10B is a cross-sectional view taken along line AA in FIG. 10A.

  Hereinafter, the detailed structure of the bearing portion 3a and the method of attaching the connecting portion 4 to the bearing portion 3a will be described with reference to FIG. 9 and FIG.

  As shown in FIGS. 9 and 10B, the connecting portion 4 has a hole portion 4a, the first guide portion 3b of the bearing portion 3a has a hole portion 3f, and the second guide of the bearing portion 3a. The part 3c has a hole 3g.

  The central axes of the hole 4a, the hole 3f, and the hole 3g are respectively coaxial when the connecting portion 4 is provided between the first guide portion 3b and the second guide portion 3c.

  Before the cover 2a of FIG. 8 for covering the first support 2 and the back surface of the bearing portion 3a is attached, the rotation lock unlocking member 30 is attached to a predetermined position on the back surface side of the bearing portion 3a.

  A connecting portion 4 is provided between the first guide portion 3b and the second guide portion 3c of the bearing portion 3a. At this time, the first bearing 40 and the second bearing 41 are provided so as to be in close contact with both surfaces of the connecting portion 4 and one surface of the first guide portion 3b and the second guide portion 3c, respectively.

  In the above state, the rotation shaft 31 is provided with the hole 30a of the rotation lock unlocking member 30, the hole 3f of the first guide 3b, the second bearing 41, the hole 4a of the connecting portion 4, and the first. The bearing 40 and the hole 3g of the second guide portion 3c are respectively fitted.

  Here, in the present embodiment, the rotation shaft 31 has a rotation shaft portion 34 and a rotation adjustment portion 35 that is coaxial with the rotation shaft portion 34 and is formed in a cylindrical shape having a large diameter.

  The rotation adjustment portion 35 of the rotation shaft 31 is fitted into the hole 30 a of the rotation lock unlocking member 30. As for the rotation adjustment part 35, the plunger contact part 36 which consists of a some linear convex part is provided in the side surface along the Y-axis direction, respectively, for example at 15 degree intervals. Moreover, the rotation lock unlocking member 30 is provided with a plunger hole 30c.

  When the rotation adjusting unit 35 is fitted into the hole 30a of the rotation lock unlocking member 30, the plunger 37 is fitted into the plunger hole 30c toward the hole 30a of the rotation lock unlocking member 30. Combined.

  In this case, as the rotation shaft 31 rotates, the plunger 37 abuts against the plunger abutting portion 36 provided at a predetermined interval, so that the operator can change the inclination angle of the rotation column 5 of FIG. It becomes easy to grasp, and it is prevented that the rotation support | pillar 5 inclines rapidly.

  The rotation shaft portion 34 of the rotation shaft 31 is provided with a plurality of connecting hole portions 31c along the Z-axis direction so as to pass through the center point of the cross section.

  The rotation shaft 31 is formed of the hole 30a of the rotation lock unlocking member 30, the hole 3f of the first guide 3b, the bearing 41, the hole 4a of the connecting portion 4, the bearing 40 and the second guide 3c. After being fitted in the holes 3g, the rotating shaft 34 is fixed to the connecting part 4 by the set screw 38 through the connecting hole 31c. With such a configuration, the rotation shaft 31 also rotates as the connecting portion 4 rotates.

  Further, in the present embodiment, the stopper 44 is disposed above the first guide portion 3b from the vertical hole portion 30d provided in the rotation lock unlocking member 30 and the vertical hole provided in the rotation adjustment portion 35. By fitting the portion 35a, the rotation of the connecting portion 4 can be prevented. Thereby, the rotation support | pillar 5 can be fixed vertically, without making it incline.

  A lid 42 is attached from the stage S side so as to cover the hole 3g of the second guide portion 3c. The lid 42 has a hole 42a. The fixing screw 43 is fitted into a hole 31d provided on the end surface of the rotating shaft 31 through the hole 42a.

  In the present embodiment, by using the X-axis adjustment screw 93a and the Y-axis adjustment screw 93b, the rotation center of the rotation column 5 and the optical axis R2 of the camera 10 when viewed from the Y-axis direction can be easily obtained. Can be matched. That is, the rotation axis R1 of the rotation column 5 and the optical axis R2 of the camera 10 can be easily made orthogonal. Thereby, even when the measuring object W is observed from an oblique direction by inclining the rotating support column 5, the observation point on the measuring object W and the desired observation point are observed in a focused state without being deviated. can do. In particular, when the camera 10 with a high magnification (for example, 100 times to 500 times) is used, the above-described effect appears remarkably.

  Here, as described above, whether or not the rotation axis R3 of the stage S is coincident with the optical axis R2 of the camera 10 is determined as follows.

  First, an image on the stage S on which the measurement object W is not placed is displayed on the screen of a display (not shown) by the camera 10. Then, the stage S is rotated.

  In this case, the image of the mark on the stage S (for example, unevenness and scratches) moves so as to draw a circle with reference to the center of the display screen. Here, the position of the mark (for example, unevenness and scratches) at the rotation center of the image rotating on the screen corresponds to the rotation center of the stage S. Therefore, if the mark at the rotation center of the image matches the center of the screen, it is determined that the rotation axis R3 of the stage S and the optical axis R2 of the camera 10 match.

  Conversely, if the mark at the rotation center of the image is off the center of the screen, it is determined that the rotation axis R3 of the stage S and the optical axis R2 of the camera 10 do not match.

  As described above, when the rotation axis R3 of the stage S and the optical axis R2 of the camera 10 do not coincide with each other, the operator uses the X-axis adjustment screw 93a and the Y-axis adjustment screw 93b to thereby rotate the rotation axis of the stage S. R3 and the optical axis R2 of the camera 10 can be matched. Since the rotation axis R1 of the rotation column 5 and the rotation axis R3 of the stage S are preset so as to be orthogonal to each other, the operator uses the X-axis adjustment screw 93a and the Y-axis adjustment screw 93b. By making the rotation axis R3 coincide with the optical axis R2 of the camera 10, the rotation axis R1 of the rotation column 5 can be made orthogonal to the optical axis R2 of the camera 10.

  As a better method, for example, a circle with a diameter of 10 mm is drawn on the screen of the display using predetermined software. When the stage S is rotated, if the mark at the center of rotation of the image moves so as to fall within the circle having a diameter of 10 mm, the rotation axis R3 of the stage S and the optical axis R2 of the camera 10 coincide. It is judged that

  Conversely, if the mark at the center of rotation of the image does not move so as to fall within the circle with a diameter of 10 mm, that is, if it does not move out of the circle with a diameter of 10 mm, the rotation axis R3 of the stage S and the camera 10 Is determined not to coincide with the optical axis R2.

  If the stage S is restrained so as not to move in the X-axis direction and the Y-axis direction instead of the marks such as the unevenness and scratches on the stage S as described above, it becomes a mark on the stage S, for example. A stamp may be provided, or a mark may be provided.

  As a result, even when the camera 10 is replaced, by using the X-axis adjustment screw 93a and the Y-axis adjustment screw 93b, the rotation center of the rotation column 5 and the optical axis of the camera 10 when viewed from the Y-axis direction. R2 can be easily matched. That is, the rotation axis R1 of the rotation column 5 can be easily made orthogonal to the optical axis R2 of the camera 10. Therefore, various cameras 10 can be used easily.

  Usually, the operator releases the restraint of the rotation shaft 31 by the rotation lock unlocking member 30, and observes the measuring object W, while rotating the rotation column 5 clockwise or counterclockwise several times. Tilt. In this case, a large load is applied to the rotating shaft 31.

  In the present embodiment, since the connecting portion 4 with which the rotating shaft 31 is fitted is supported from both sides by the first bearing 40 and the second bearing 41, the rotating shaft 31 is inclined from the horizontal direction. Is reliably prevented.

  Further, in the present embodiment, the cable C is inserted and restrained by the cable restraint 3d, so that even when the camera 10 to which the cable C is connected is tilted along with the tilt of the rotating support column 5. In addition, it is possible to prevent rattling at the connection portion between the camera 10 and the cable C and to prevent the cable C from being forcibly pulled due to the inclination of the camera 10. Thereby, even when the camera 10 is tilted and the measurement object W is observed, the position of the camera 10 can be stabilized.
