In addition, the same code | symbol is attached | subjected and demonstrated about a part equivalent or equivalent to the prior art example of FIG.
In FIG. 1, reference numeral 1 denotes a fixed substrate fixed in the space stabilizer 1 </ b> A of FIG. 9 described above. A first movable substrate 7 is connected to a tongue piece 4 of the fixed substrate 1 via a bolt 5. Thus, it is configured to be able to rotate at a required angle along the elevation direction indicated by the arrow B around the shaft support portion 30 for the elevation direction rotation center.

A pair of first stopper bolts 31 and 32 are provided at the end portion 7A of the first movable substrate 7, and a stainless steel having a predetermined thickness is formed between the end portion 7A and the inner surface 1a of the fixed substrate 1. An elevating direction spacer 33 is provided, and each of the first stopper bolts 31 and 32 passes through a hole (not shown) formed in the elevating direction spacer 33 in advance, and the screw hole ( (Not shown).
Therefore, the by fixing by tightening the respective first stopper bolt 31, the first movable substrate 7 along the elevation angle amount corresponding arrow B corresponding to the plate thickness T ₁ of the said elevation direction spacers 33 of elevation It is comprised so that it may be fixed in the state.

The first movable substrate 7 is pivoted at a required angle in a turning direction indicated by an arrow C about a turning direction rotation center shaft support portion 30A made of a bolt screwed to the first movable substrate 7. A second movable substrate 34 that can be provided is provided.
The first protrusion 35 provided at the end 34A of the second movable substrate 34 and the second protrusion 36 formed at the end 7A of the first movable substrate 7 correspond to the vertical direction in the drawing. located Te, the turning direction spacers 37 having a predetermined thickness T ₂ made of stainless or the like between the projections 35 and 36 are provided, said projections 35, 36 inserted through the second projection 36 The second stopper bolt 40 is fixed by a second stopper bolt 40 that passes through a hole (not shown) of the turning direction spacer 37 and is screwed into a screw hole (not shown) of the first protrusion 35.
Therefore, by changing the thickness T ₂ of the said turning direction spacers 37, the second movable board 34 is configured to pivot along only the plate thickness T ₂ minutes arrow C depending on the thickness T ₂ ing.

A box-shaped imaging device 10 provided with a camera, an infrared camera, a laser device, and the like is fixed to one surface of the second movable substrate 34 via bolts 11.
Therefore, in the above-described configuration, when the imaging device 10 shown in FIG. 1 is mounted inside a space stabilizer (not shown), a predetermined mounting in the space stabilizer using the plurality of mounting holes 1A of the fixed substrate 1 is performed. It can be fixed to a member (not shown). Further, when adjusting the optical axis of the imaging device 10, after removing the first stopper bolts 31 and 32 from the end portion 7 </ b> A of the first movable substrate 7, a plate thickness T ₁ required for optical axis alignment in advance. The first movable substrate 7 is rotated and set to a predetermined elevation angle by exchanging the spacer 33 for the elevation direction and tightening the first stopper bolts 31 and 32 again.

The first movable substrate 7 is actually divided into two bodies as shown in FIGS. 2 and 7, and the rotation pin 60 is the center of rotation on the end 7 </ b> A side of the first movable substrate 7. As described above, the auxiliary substrate 7B is configured to rotate and bend along the elevation direction B.
The first stopper bolts 31 and 32 are provided on the auxiliary board 7B, the rotary pin 60 employs a known rotary pin link structure as shown in FIG. 4, and the auxiliary board 7B is as shown in FIG. Even if it is bent in the direction, the rotation pin 60 can move outward in the elongated hole 60a (that is, the auxiliary substrate 7B can also move outward), so that the auxiliary pin 7 and the inner surface 1a of the first fixed substrate 1 can be auxiliary. The auxiliary substrate 7B is configured such that it can be held in a parallel relationship with the inner surface 7Ba of the substrate 7B. . Therefore, by tightening the first stopper bolt 31 in the above-described state, the first movable substrate 7 can be held at an elevation angle corresponding to the thickness of the elevation-direction spacer 33.

When it is bent, that is, rotated by an angle that can be understood by visual inspection), as shown in (B), the spacer 33 for the elevation direction is crushed and deformed into a trapezoidal shape, and the state of the deformation is likely to change over time. In this case, the optical axis 10a of the imaging device 10 is also to be changed. That is, it is difficult to maintain the set optical axis 10a for a long period of time.

  Therefore, as shown in FIG. 7, each inner surface is bent by turning the auxiliary substrate 7B of the first movable substrate 7 in contact with the spacer 33 for the elevation direction by rotating the auxiliary substrate 7B with the rotation pin 60 with respect to the first movable substrate 7. By making 1a and 7Ba parallel to each other, the elevation direction spacer 33 does not abut against the elevation direction spacer 33 as shown in FIG. In addition, the optical axis 10a of the imaging device 10 can be stably maintained for a long time.

Then, when adjusting the swivel angle is replaced with the second turning direction spacers 37 having a thickness T ₂ of the stopper bolt 40 is removed and requires the pre-centration of the turning direction spacers 37 When the second stopper bolt 40 is tightened again, the second movable substrate 34 is set to rotate to a predetermined elevation angle.
