示す図である。 A fine movement device for a rotating screen used in a conventional projection inspection device will be explained with reference to FIGS. 1 and 2.
In FIG. 1, a rotating frame 2 holds a rotating screen 3, and is rotatably supported by a fixed frame 1 by known means such as a ball bearing (not shown). The rotation angle of the rotating frame 2 can be read by an angle scale 2a carved on the rotating frame 2 and a vernier scale 4a of a vernier scale 4 fixed to the fixed frame 1. Rotation of the handle 5 causes the rotating frame 2 to move slightly. The clamp screw 6 fixes a rotating shaft (not shown) of the handle 5. FIG. 2 is a cross-sectional view taken along the line A-A' in FIG. 1, mainly showing the cross-section of the fine adjustment handle.

角回転が困難となる。 Fine movement handle support 1 provided on fixed frame 1
A and 1b rotatably support a rotating shaft 7 having a handle 5 fixed to its upper end, and a friction wheel 8 fixed to its lower end. The rotation of the friction wheel 8 can be clamped by pressing the rotary shaft 7 with a clamp screw 6 screwed into the fixed frame 1. An elastic material such as rubber is used for the friction wheel 8 in order to increase the coefficient of friction with the rotating frame 2. However, if such elastic material is left unused for a long time, it may permanently deteriorate due to contact pressure. This causes deformation, and as it rotates, wobbling occurs in the vicinity, making small angle rotation difficult.
本考案は、このような従来の欠点を解決し、摩
擦車の変形を防止した微動装置の提供を目的とす
る。 The object of the present invention is to provide a fine movement device that solves the above-mentioned conventional drawbacks and prevents deformation of the friction wheel.
以下、実施例に基づいて本考案を説明する。第

The figure shows a state where the friction wheel 8 is in contact with the side surface of the rotating frame 2 and the fine movement device is set, and FIG.
This shows the state in which the fine adjustment device has been reset by detaching from the side of the device. In addition, Fig. 5 shows B- in Fig. 3.

図に示した如く、摩擦車８が回転枠２の側面にば
ね１２の力によつて押圧されることになる。この
状態でハンドル５を回転すれば、摩擦車８が回転
しそれによつて回転枠２も回転する。 The clamp screw 6' of the rotating frame 2 and the rotating shaft 7 of the friction wheel 8 are connected by a connecting arm 10. The connecting arm 10 is formed with a through hole through which the rotating shaft 7 is rotatably passed, and a female thread into which the male thread of the clamp screw 6' is screwed. The connecting arm 10 is
It is rotatably supported by a pin 1' fixed to the main body 1 in the plane of the paper in FIG. be done. Therefore, in the operating state, the third
As shown in the figure, the friction wheel 8 is pressed against the side surface of the rotating frame 2 by the force of the spring 12. If the handle 5 is rotated in this state, the friction wheel 8 will rotate, and the rotating frame 2 will also rotate accordingly.
次に、クランプねじ６′を右回転すると、クラ

じ６′は回転枠２をしつかりとクランプする。従
つて、この状態（不作動状態）にて長時間放置し
ても摩擦車８には力が働らかないので、摩擦車の
変形の問題は生じない。 Next, when the clamp screw 6' is rotated clockwise, the tip of the clamp screw 6' gradually protrudes from the connecting arm 10 toward the side surface of the rotating frame 2, and finally comes into contact with the side surface. When the clamp screw 6' is further rotated clockwise, the reaction force causes the connecting arm 10 to rotate in a direction away from the side surface of the rotating frame 2 against the pressing force of the spring 12. As a result, as shown in FIG.
is separated from the side of the rotating frame 2. Of course, the clamp screw 6' firmly clamps the rotating frame 2. Therefore, even if the friction wheel 8 is left in this state (non-operating state) for a long time, no force is applied to the friction wheel 8, so that the problem of deformation of the friction wheel does not occur.
なお、以上の例では、摩擦車によつて移動部材
（上記例では回転枠）が回転移動する例をあげた
が、移動部材は第６図の６０の如き直線移動する
ものでも良いことは勿論である。 In the above example, the movable member (rotating frame in the above example) is rotated by a friction wheel, but it goes without saying that the movable member may be one that moves linearly, such as 60 in Fig. 6. It is.
また、以上の例では、連結枠が回転可能に本体
に軸支されていたが、連結腕は移動部材の方向に
のみ案内されれば良いのであつて、例えば、第６

れによつて、連結腕は回転することなく移動す
る。 Further, in the above example, the connecting frame is rotatably supported by the main body, but the connecting arm only needs to be guided in the direction of the moving member.
As shown in the figure, left and right guide members 61 and 62 for guiding both ends of the connecting arm may be provided. Thereby, the connecting arm moves without rotating.
以上述べた如く本考案の微動装置はクランプね
じによる移動部材のクランプに連動して摩擦車を
移動部材から離脱せしめる如き構成であるから、
長時間不使用の場合は摩擦車を自由な状態にして
おくことができ、従つて、摩擦車の変形を防止す
ることができる。 As described above, the fine movement device of the present invention is configured such that the friction wheel is separated from the moving member in conjunction with the clamping of the moving member by the clamp screw.
If the friction wheel is not used for a long period of time, the friction wheel can be left in a free state, and therefore deformation of the friction wheel can be prevented.
