構は以上のような問題があった。Since the conventional holding mechanism for the optical parts is constructed as described above, the adjustment accuracy depends on the processing and assembling accuracy of the screw part, and the screw part is required for precise adjustment. It was necessary to improve the processing and assembling accuracy. In addition, after adjusting the angle, the fixed part and the movable part are indirectly connected by point contact through the screw with the azimuth direction adjustment screw, the elevation direction adjustment screw, and the fulcrum. It was difficult to maintain the angle due to fluctuations. For example, due to impact, the azimuth direction adjusting screw, the elevation direction adjusting screw, and the position of contact with the fixed portion of the tip portion of the fulcrum are displaced. When the position of the tip is displaced, the screw contact surface of the fixed portion is not a perfect flat surface, so the distance between the fixed portion and the movable portion changes, and the angle of the movable portion with respect to the fixed portion is displaced. Further, the screw portions of the azimuth direction adjusting screw and the elevation adjusting screw have play, and they are pressed against one side and fixed by a spring, but the contact state changes due to vibration. When the contact state of the screw portion changes, the inclination of the screw with respect to the movable portion changes, and the angle of the movable portion with respect to the fixed portion changes. If a fixing mechanism other than the adjusting mechanism is provided, the holding state is improved, but the adjusting procedure becomes complicated. For example, there is a method in which a fixed portion near each adjustment screw is provided with a screw hole, and the movable portion is fixed to the fixed portion by fastening the fixing screw. When adjusting, it is necessary to first loosen the fixing screws near each adjustment screw, and then tighten the fixing screws again after the adjustment. In general, the optical axis adjustment is rarely performed by a single adjustment mechanism, and adjustment is often performed by combining adjustment mechanisms at several places. It is complicated to perform adjustments at several places including the operation of the fixing screw. The conventional optical component holding mechanism has the above problems.

The outer surface is held, and the optical component mounting portion to which the optical component is mounted is held on the inner surface of the adapter.

る。In the optical component holding mechanism according to the present invention, when the cylindrical surface outside the adapter is rotated along the cylindrical surface provided in the fixing portion, the central axis of the cylindrical surface inside the adapter is the center of the external cylindrical surface. Since it is inclined with respect to the axis, the central axis of the cylindrical surface inside the adapter rotates while maintaining a constant angle with respect to the central axis of the external cylindrical surface. The holding direction of the optical component can be changed by fixing the optical component mounting portion to which the optical component is mounted on the inner cylindrical surface and rotating the adapter.

The inner cylindrical surface of the adapter 4 is inclined with respect to the outer cylindrical surface, and the optical component mounting portion 5 is fitted inside the inner cylindrical surface. A mirror 6 is put in the optical component mounting portion 5, and the mirror 6 is fixed by a fixing ring 7. Since the adapter 4 can rotate within the fixed portion 3, rotating the adapter 4 can change the direction in which the mirror faces. Furthermore, since the optical component mounting portion 5 can be rotated inside the adapter 4, the direction in which the mirror faces can be changed while maintaining the vertical direction of the mirror. By rotating the adapter 4, the angle in the elevation direction can be adjusted.

である。As described above, according to the present invention, both the angle adjustment in the elevation direction and the angle adjustment in the azimuth direction can be realized while the parts are in surface contact. When the surface accuracy is improved in the surface contact, unlike the point contact, the contact position does not change or the contact state does not change due to disturbance, and the fluctuation after adjustment is small. Also, during adjustment,
Since the surfaces are slid and moved, the contact state does not change during adjustment like point contact, and high-precision adjustment is possible.

When the inclination of the outer surface and the inner surface of the adapter 4 is θ, the variable range is ± θ,
The angle change in the elevation direction per 1-degree rotation angle of the adapter is θ / 360, and minute angle adjustment is possible.
