ための図示および説明は省略する。Such a positioning mechanism 1 includes a drive mechanism 8 as shown in FIG. That is, the drive mechanism 8 is connected to the guide rail 3
Threaded shafts loa and 10b interposed between support members 9a and 9b at both ends of support base 2 so as to be oriented in the same direction as the axial direction of a and 3b, and a female threaded member that moves forward and backward on the threaded shafts 10a and fob. 11a, llb, and drive motors 12a, 12b attached to one end of the screw shafts 10a, 10b. The female thread member 11
a and llb are respectively attached to the first sliding member 4a and the second sliding member 4b. That is, as shown in FIG. 3, among the female threaded members 11a and llb, the female threaded member 11b is placed below the second sliding member 4b, which is placed between the guide rails 3a and 3b so as to pass the hook. It is built into the protruding part. Note that since the female threaded member 11a is similarly attached to the first sliding member 4a, illustration and explanation thereof will be omitted.
かかる構成のテーブルの位置決め機構１の動作は以下の
通りである。The operation of the table positioning mechanism 1 having such a configuration is as follows.
駆動用モータ１２ａ、１２ｂが駆動することにより、ね

の場合、前記ねじシャフトｌｏａ、１０ｂは同一方向に
回転することにより、第１摺動部材４ａおよび第２摺動
部材４ｂは、同一距離だけ、ガイドレール３ａ、３ｂ上
（Ｘ軸）を摺動し、テーブル７を所望の位置に移動保持
することができる（第４図参照）。By driving the drive motors 12a and 12b, the threaded shafts loa and IOb rotate, and the female threaded member 11a
, llb move forward and backward on the screw shafts loa and 10b together with the first sliding member 4a and the second sliding member 4b. In this case, the screw shafts loa and 10b rotate in the same direction, so that the first sliding member 4a and the second sliding member 4b slide on the guide rails 3a and 3b (X axis) by the same distance. The table 7 can be moved and held at a desired position (see FIG. 4).
また、駆動用モータ１２ａ、１２ｂのいずれか一方のみ

方向である上下方向（Ｚ軸）にテーブル７を昇降調節し
、移動保持させることが出来る（第５図参照）。Further, by driving only one of the drive motors 12a and 12b and changing the relative position between the first sliding member 4a and the second sliding member 4b, the parallel link 5 and the link 6 are displaced, The table 7 can be adjusted up and down in the vertical direction (Z-axis), which is perpendicular to the axial direction of the guide rails 3a and 3b, and can be kept moving (see FIG. 5).
なお、平行リンク５およびリンク６を第６図に示すよう
に、第１摺動部材４ａおよび第２摺動部材４ｂの上面と
、テーブル７のガイドレール３ａ、３ｂに対向する面に
取り付けるようにすれば、テーブル７を水平方向（Ｙ軸
）に移動調節することが出来る。Note that, as shown in FIG. 6, the parallel links 5 and 6 are attached to the upper surfaces of the first sliding member 4a and the second sliding member 4b, and to the surface of the table 7 facing the guide rails 3a and 3b. Then, the table 7 can be moved and adjusted in the horizontal direction (Y-axis).
このように、本発明によれば、ガイドレール３ａ、３ｂ
の軸方向に第１摺動部材４ａおよび第２摺動部材４ｂを
移動して、位置を制御することにより、２軸方向の位置
決めが可能となる。Thus, according to the present invention, the guide rails 3a, 3b
By moving the first sliding member 4a and the second sliding member 4b in the axial direction and controlling their positions, positioning in two axial directions becomes possible.
また、ガイドレール３ａ、３ｂの軸方向を位置決めすべ

定まるので、その分、位置決め機構１の占有スペースは
小さくてすむ。Furthermore, by aligning the axial direction of the guide rails 3a, 3b with one axis (X-axis) of the two axes for positioning, the driving motors 12a, 12b can be installed in one location. Therefore, the space occupied by the positioning mechanism 1 is small.
さらに、２軸方向のうちの他軸（Ｙ軸またはＺ軸）へは

他軸方向への駆動機構および特別な伝達機構は不要で構
成が簡略化されたものとなる。Furthermore, since the configuration is such that the table 7 is moved in the same direction as the other one of the two axes (Y axis or Z axis) by indirect movement of the parallel links 5 and links 6,
A drive mechanism in the other axis direction and a special transmission mechanism are unnecessary, and the configuration is simplified.
以上、本発明にかかるテーブルの位置決め機構について

。The table positioning mechanism according to the present invention has been described above with reference to one embodiment, but a linear motor can also be applied to the drive mechanism. If such a linear motor is applied, the space for the drive motors 12a, 12b becomes unnecessary, and the space of the positioning mechanism can be saved.
