この考案は、分光光度計等の光学素子として用いられる
ミラーの保持機構に関し、特に水平面内び鉛直面内にお
けるミラーの位置調整を容易に行えるその保持機構に関
する。The present invention relates to a holding mechanism for a mirror used as an optical element such as a spectrophotometer, and more particularly to a holding mechanism for easily adjusting the position of the mirror within a horizontal plane and a vertical plane.

傾き（Ｚ方向）の調整を行っている。In the conventional mirror holding mechanism, as shown in FIGS. 2A and 2B, the mirror 1 is held by two members 8 and 9 with respect to a base (not shown). That is, the positioning plate 9 is fixed to the base, and then the holder 8 to which the mirror is attached is attached to the plate 9. The position of the mirror is adjusted in the XY direction in the horizontal plane within the range of the degree of freedom between the fixing screw 10 and the screw hole for fixing the positioning plate 9 to the base, and then the holder 8 is adjusted. Is fixed to the plate 9. At this time, similarly, the position adjustment in the XY direction is performed within the range of the degree of freedom between the fixing screws 11 and 12 and their screw holes, and 2
The inclination (Z direction) in the vertical plane is adjusted by the tightening condition of the one fixing screw 12.

することを目的とする。In the conventional mirror holding mechanism, it is composed of two members, the number of parts is large in combination with the number of fixing screws used, the assembly is troublesome, and the degree of freedom of position adjustment is unnecessarily high. There was a problem that adjustment was not easy. It is an object of the present invention to provide a mirror holding mechanism which has a small number of parts and which can be easily adjusted without useless play (degree of freedom).

うに必要に応じて長穴とすることが効果的である。In order to achieve the above object, in the mirror holding mechanism of the present invention, the mirror is fixed to one L-shaped holder,
A hemispherical projection is formed on the lower surface of the mounting part of the holder to the base, and a fixing screw hole having a degree of freedom with respect to the fixing screw is formed in the mounting part, and a part of the hemispherical projection is fitted. A pin hole to be inserted is formed in the base. It is effective that the screw holes and the pin holes formed in the base are elongated holes as needed, as described later.

向）に傾く。The hemispherical projection formed on the lower surface of the mounting portion of the L-shaped holder of the mirror holding mechanism configured as described above is used as a pin, and the mirror is positioned by fitting with a pin hole formed in the base. At this time, position adjustment is performed in a horizontal plane centered on the pin by the degree of freedom between the fixing screw and the screw hole. Here, the accuracy of the position adjustment of the mirror is usually much coarser than the processing accuracy, and therefore positioning by pins or the like does not cause any problem. In particular, when severe focus is required, the screw hole and pin hole are formed as long holes so that they can move in the front-back direction with respect to the optical axis, and the degree of freedom between the screw hole and the fixing screw is combined. By adjusting them, it is possible to adjust the position delicately. After adjusting the position in the horizontal plane, tighten the fixing screw,
The degree of tightening adjusts the tilt of the mirror in the vertical plane and fixes it at a good position. If you tighten it too tightly, the mounting part of the holder will be distorted and the mirror part will tilt forward (to the left in the figure).

In the figure, L with the mirror 1 attached by appropriate means
A hemispherical projection 4 is formed on the lower surface of the attachment 2 ′ of the character-shaped holder 2 to the base 3 by pressing or the like, and a pin hole 7 into which a part of the projection 4 is fitted is formed in the base 3. Pin hole 7
Is a long hole shape in the optical axis direction (left and right direction in the figure). On the other hand, the holder mounting portion 2'is provided with an elongated hole-shaped fixing screw hole 6 having a degree of freedom with respect to the fixing screw 5. The fixing screw 5 uses a so-called double nut of a set screw and a nut in order to adjust and fix the degree of tightening of the holder 2 to the base 3.
この考案は、以上説明したように構成されているので、

The reduction in the number of parts leads to cost reduction and easy mirror position adjustment.
