くの時間を要した。This conventional adjustment device, as shown in Fig. 1a and b,
In order to adjust the height of the sub-reflector 1, that is, the position and inclination in the h direction, a support member 2 fixed to the sub-reflector fixing surface 5,
Adjustment is made by increasing or decreasing the number of adjustment pieces 4 inserted between the adjustment fitting 3 bolted to the flange 6a of the sub-reflector support cylinder 6. This adjustment is a stepwise adjustment, and the thickness Adjustment required a lot of time because different adjustment pieces were used in selected combinations.
また横方向位置の調整は、フランジ６ａと補強金具３と
を結合するボルト穴は互いに交差する長円形の穴として
、ボルト７をゆるめて互いに横方向に滑らせて行うので
あるが、手加減により移動させるので、円滑な調整はで
きなかった。Further, adjustment of the lateral position is performed by making the bolt holes that connect the flange 6a and the reinforcing metal fitting 3 into oval holes that intersect with each other, and by loosening the bolts 7 and sliding them in the lateral direction. Therefore, smooth adjustment was not possible.
本考案はこのような従来の欠点を改良して、副反射鏡の

る。In FIGS. 2a and 2b, 11 is a support member with an elongated hole 23, 12 is an adjustment fitting having a screw hole and an elongated hole of the same pitch as the length of the support member 11, and 13 and 14 are the support member 11.
A connecting bolt and a connecting nut for connecting the adjustment fitting 12, 1
5 has a proximal end 16 on one side, the proximal end 16 is rotatably attached to the rear surface member lea of the sub-reflector 10, and the screw part 17 screwed into the screw hole of the adjustment fitting 12 and the knob part 1 on the other side.
8 is an adjustment rod, 19 is a fixing nut that fixes the adjustment metal fitting 12 and the adjustment rod 15, and 21 is screwed into a screw hole of a protruding piece 22 of the adjustment metal fitting 12, and the tip abuts the support member 11, and the adjustment metal fitting 12 is fixed. This is a push bolt for horizontal movement.

傾きを所定の位置に調整し、次に固定ナツト１９により
調整棒１５を調整金具１２に固定する。In the sub-reflector adjusting device having such a configuration, when adjusting the position of the sub-reflector 10, first tighten the fixing nut 19.
Loosen the knob 18 of the adjustment rod 15 with a spanner or the like, rotate the adjustment rod 15 to adjust the height and inclination of the sub-reflector 10 to the predetermined position, and then tighten the fixing nut 19 to tighten the adjustment rod 15. is fixed to the adjustment fitting 12.

に調整金具１２を固定する。Furthermore, in order to adjust the lateral position of the sub-reflector, loosen the coupling nut 14 and use the push bolt 21 to adjust the adjustment fitting 12.
After adjusting the support member 11 to a predetermined lateral position by sliding it relative to the support member 11, tighten the coupling nut 14.
Fix the adjustment fitting 12 to.
以上説明したように、本考案は副反射鏡の高さおよび傾
