【従来の技術】[Prior art]

従来図2に示す構成において、試料扉1と、試料扉駆動部10と、回転試料テ ーブル2と、回転試料テーブル駆動部12と、試料扉1と回転試料テーブル駆動 部12とを制御する制御部13によって、試料扉1に試料5が衝突しないように 制御が行われていた。 Conventionally, in the configuration shown in FIG. 2, control for controlling the sample door 1, the sample door drive unit 10, the rotary sample table 2, the rotary sample table drive unit 12, the sample door 1 and the rotary sample table drive unit 12 The part 13 was controlled so that the sample 5 did not collide with the sample door 1.

【0003】 また、試料扉1は筐体8をベースに駆動しているため、調整なしに回転試料テ ーブル2を上下させることはできなかった。Further, since the sample door 1 is driven based on the housing 8, the rotating sample table 2 cannot be moved up and down without adjustment.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかし、従来の方法では試料扉駆動部10と、回転試料テーブル駆動部12と 、回転試料テーブル2と試料扉1の同期を取る制御部13を備えるが必要がある という課題がありまた、膜厚を正確に求めるために、試料5の高さ変化に応じて 回転試料テーブル2を上下させる必要があるが、そのつど試料扉1の移動範囲を 変更するための調整が必要であった。 However, the conventional method has a problem that it is necessary to include the sample door driving unit 10, the rotary sample table driving unit 12, and the control unit 13 for synchronizing the rotary sample table 2 and the sample door 1 and the film thickness. In order to accurately obtain the value, it is necessary to move the rotating sample table 2 up and down according to the change in the height of the sample 5, but it is necessary to adjust the moving range of the sample door 1 each time.

【0005】 本考案の目的は、従来のこのような課題を解決するため、試料扉を開閉するた めの専用の動力源を不要とし、制御部13の制御なしで扉と回転試料テーブル2 の同期を取り、同時に回転試料テーブル2を上下させても調整が不要である機構 を得ることである。The object of the present invention is to solve the conventional problems as described above, eliminating the need for a dedicated power source for opening and closing the sample door, and controlling the door and the rotary sample table 2 without the control of the control unit 13. It is to obtain a mechanism that requires no adjustment even if the rotary sample table 2 is moved up and down at the same time in synchronization.

【課題を解決するための手段】[Means for Solving the Problems]

上記課題を解決するために、この考案は、X線発生部と、蛍光X線検出部と、 試料交換時にX線照射を停止するためのX線シャッターと、複数の試料を設置可 能で、しかも1個以上の試料を筐体の外部に露出し、外部から試料を操作可能な 構造の回転試料テーブルと、試料交換時に開閉させる試料扉と、X線を遮蔽する ための筐体とを備える蛍光X線膜厚計において、前記回転試料テーブルの外周に 試料扉を上下動させるガイドを設け、試料テーブルの回転に連動して試料扉が上 下動することにより試料交換ができ、回転試料テーブル上に溝を設け試料扉が溝 の中まで下降することによって、確実にX線を遮蔽できる蛍光X線膜厚計である 。前記回転試料テーブルの外周に設けられたガイドは、試料測定位置において試 料扉を下降させ、回転中は、試料扉を押し上げるように形成されており、試料扉 には、回転試料テーブルのガイドに沿って上下動する機構が設けられている。 In order to solve the above problems, the present invention can install an X-ray generation unit, a fluorescent X-ray detection unit, an X-ray shutter for stopping X-ray irradiation during sample exchange, and a plurality of samples. In addition, it is equipped with a rotating sample table that exposes one or more samples to the outside of the housing so that the samples can be operated from the outside, a sample door that opens and closes during sample replacement, and a housing that shields X-rays. In the X-ray fluorescence film thickness meter, a guide for moving the sample door up and down is provided on the outer periphery of the rotating sample table, and the sample door can be moved up and down in conjunction with the rotation of the sample table, so that the sample can be replaced. It is a fluorescent X-ray film thickness meter that can reliably shield X-rays by providing a groove on the top and moving the sample door down into the groove. The guide provided on the outer circumference of the rotating sample table is configured to lower the sample door at the sample measurement position and push up the sample door during rotation, and the sample door serves as a guide for the rotating sample table. A mechanism is provided for moving up and down along.

【作用】[Action]

上記のように構成された蛍光X線膜厚計において、外周に設けられたガイドに よって回転試料テーブルの回転する力を垂直方向に分配し、試料扉を上昇させ、 自重またはばね等によって試料扉を下降させることで、他の動力源を用いずに上 下動をさせることができ、同時に回転試料テーブルと試料扉の動作の同期を取る ことができる。また、回転試料テーブルの測定位置に試料扉が収まる溝を設け測 定時に試料扉がその溝の中に収まることによって、確実にX線を遮蔽することが できる。 In the fluorescent X-ray film thickness meter configured as described above, the rotating force of the rotating sample table is vertically distributed by the guide provided on the outer periphery, and the sample door is raised, and the sample door is moved by its own weight or springs. By lowering, it is possible to move up and down without using any other power source, and at the same time, the operations of the rotating sample table and sample door can be synchronized. In addition, by providing a groove for accommodating the sample door at the measurement position on the rotating sample table, and by allowing the sample door to be accommodated in the groove during measurement, X-rays can be reliably shielded.

【0008】 また、上記構成の回転試料テーブルが上下動できる場合において、測定試料 の高さに合わせて回転試料テーブルを上下させれば、それに応じて試料扉が上下 動するため、従来技術で記述したような、機械的な調整は不要となる。Further, in the case where the rotating sample table having the above-mentioned configuration can be moved up and down, if the rotating sample table is moved up and down according to the height of the measurement sample, the sample door moves up and down accordingly. There is no need for mechanical adjustment as described above.

【実施例】【Example】

以下に、この考案の実施例を図に基づいて説明する。 図1において、筐体8の中には、試料5に照射するX線を発生するX線発生部 6と、そのX線をON・OFFするシャッター4と、試料5から発生する蛍光X 線を検出する蛍光X線検出部6が、筐体8に備えられている。筐体8には窓部が 備えられており、その窓部には試料5を載置する回転試料テーブル2が備えられ ている。 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, an X-ray generation unit 6 that generates X-rays that irradiate the sample 5, a shutter 4 that turns the X-rays ON and OFF, and fluorescent X-rays that are emitted from the sample 5 are included in the housing 8. The fluorescent X-ray detection unit 6 for detecting is provided in the housing 8. The housing 8 is provided with a window portion, and the window portion is provided with the rotating sample table 2 on which the sample 5 is placed.

【0010】 回転試料テーブル2は、回転支持体20により水平に回転可能になっており、 回転試料テーブル2の一部は、X線発生部6からのX線照射位置に達しており、 また回転試料テーブル2の他の一部は筐体8の外に位置するようになっている。 また回転試料テーブル2の外周には、立上がりツバ形状のガイド3が設けられて おり、総体として凹形状をしている。The rotary sample table 2 can be horizontally rotated by the rotary support 20, and a part of the rotary sample table 2 has reached the X-ray irradiation position from the X-ray generation unit 6 and can be rotated. The other part of the sample table 2 is located outside the housing 8. Further, a rising brim-shaped guide 3 is provided on the outer periphery of the rotary sample table 2 and has a concave shape as a whole.

【0011】 更に、ガイド3には、凹部3aが設けられている。そして、筐体8の窓部には 、試料扇1が設けられており、その試料扇1は、上下方向に自重にてスライド可 能になっている。つまり、試料扇1の下端は、常にガイド3に接触していること になる。また、ガイド3の凹部3aは、試料扇1の下端が回転試料テーブル2の 試料載置面2aに接するように、回転試料テーブル2の試料載置面2aと同一面 になるように凹みが形成されている。試料扉1が下降して試料測定を実施してい る状態を示し、回転試料テーブル2の外周に設けられたガイド3の凹部で上下動 可能な試料扉1は下降し、X線シャッター4が開いても外部にX線は漏洩しない 。Further, the guide 3 is provided with a recess 3a. A sample fan 1 is provided in the window portion of the housing 8, and the sample fan 1 can slide in the vertical direction by its own weight. That is, the lower end of the sample fan 1 is always in contact with the guide 3. Further, the concave portion 3a of the guide 3 is formed so as to be flush with the sample mounting surface 2a of the rotary sample table 2 so that the lower end of the sample fan 1 contacts the sample mounting surface 2a of the rotary sample table 2. Has been done. The state where the sample door 1 is lowered to perform the sample measurement is shown. The sample door 1 which can be moved up and down by the concave portion of the guide 3 provided on the outer periphery of the rotating sample table 2 is lowered and the X-ray shutter 4 is opened. However, X-rays do not leak outside.

【0012】 次に、X線シャッター4が閉じた後、回転試料テーブル2を回転させるとき、 試料扉1は、ガイド3に沿って上昇するため、試料5と試料扉1が衝突せずに試 料交換を行うことができる。同様に、回転試料テーブル2を上下させたとき、試 料扉1が連動して上下するため、機械的調整なしに、測定試料の高さに合わせた 測定が可能となる。Next, when the rotary sample table 2 is rotated after the X-ray shutter 4 is closed, the sample door 1 rises along the guide 3, so that the sample 5 and the sample door 1 do not collide with each other and the test is performed. You can exchange fees. Similarly, when the rotating sample table 2 is moved up and down, the sample door 1 moves up and down in conjunction with each other, so that the measurement according to the height of the measurement sample can be performed without mechanical adjustment.

【0013】 また、図3に示す、回転試料テーブル2に、試料扉18が収まる溝20を設け ることにより、測定時に試料扉1が溝の中に収まり、X線の漏洩を確実に防止す ることができる。 本考案の実施にあたり、図1のX線シャッター4が開いている状態で回転試料 テーブル2を回転させた場合、試料扉1が上昇し、試料扉1の下方からX線が漏 洩するという危険や、試料扉1が開いている状態でX線シャッター4が開くこと を防止するため、試料扉1の先端に、試料扉1と回転試料テーブル2とが接触し ていることを確認するセンサーを設け、X線遮断等の安全機構を備える必要があ る。Further, by providing the rotary sample table 2 shown in FIG. 3 with the groove 20 in which the sample door 18 is fitted, the sample door 1 is fitted in the groove at the time of measurement, and the leakage of X-rays is surely prevented. You can In carrying out the present invention, when the rotating sample table 2 is rotated with the X-ray shutter 4 shown in FIG. 1 open, the sample door 1 rises and X-rays may leak from below the sample door 1. Also, in order to prevent the X-ray shutter 4 from opening when the sample door 1 is open, a sensor that confirms that the sample door 1 and the rotating sample table 2 are in contact with the tip of the sample door 1 is installed. It is necessary to provide a safety mechanism such as X-ray blocking.

【考案の効果】[Effect of device]

この考案は、以上説明したように回転試料テーブルの回転する力とタイミング を試料扉の開閉に利用できる構造としたことにより、図2の試料扉駆動部10と 回転試料テーブル駆動部12と制御部13とが不要となり、装置構成を簡略化す ることが可能となる。また従来の技術では、試料の高さが変わるたびに必要であ った試料扉の移動範囲の変更も不要となり、測定の準備作業を簡便化するという 効果が発生する。 As described above, the present invention has a structure in which the rotating force and timing of the rotating sample table can be used to open and close the sample door, so that the sample door driving unit 10, the rotating sample table driving unit 12, and the control unit shown in FIG. 13 is unnecessary, and the device configuration can be simplified. Further, in the conventional technique, it is not necessary to change the moving range of the sample door, which is required every time the height of the sample is changed, and an effect of simplifying the preparation work for the measurement occurs.
