That is, in FIGS. 1 to 3, three tables 101, 102, and 103 are provided on the main body 100 in a horizontal direction in the figure. Although these three tables have basically the same configuration, since the control unit 104 and the number key 105 are provided on the table 101, the table 10 has an external appearance.
Only one is different.

An X-axis is provided so as to penetrate these three tables 101, 102 and 103, and a Y-axis is provided with three axes Y1, Y2 and Y3 for each table. Each axis is provided with a motor as a correction means. The X axis is controlled by a motor Mx, and the Y axis is controlled by a motor.
The axes are driven by My1, My2, and My3 to perform correction by moving the tables 101, 102, and 103 along the XY coordinates.

Further, each of the tables 101, 102, 10
In order to adjust the rotation angle within the X-Y coordinates of No. 3, rotation angle correction motors Mc1, Mc2, Mc3 are provided for each table. In order to perform a correction operation using these motors, the sensors S1, S2, and S3 are provided with a drill D for each table.
1, D2, and D3.

FIG. 2 is a plan view of the embodiment of FIG. 1, and a mechanism for aligning a printed circuit board with a punching device will be described with reference to FIG. That is, in order to make holes in the printed circuit boards A, A ′, and A ″ in each table, first, four
The guide holes of the printed circuit boards A, A ', and A "are aligned with the product positioning pins 201, 202, and 203, and are mounted.

Returning again to FIG. 1, data relating to XY coordinates prepared in advance is provided to the control unit 104 by the number key 105 or an appropriate medium. Control unit 1
04 is supplied with position data representing the positional deviation from the origin detected for each table from the sensors S1, S2, S3 of the tables 101, 102, 103. Based on both of these data, the control unit 104 forms a control signal for each table and supplies a control signal to each motor of each of the tables 101, 102, and 103.

The control signals include positioning signals related to XY coordinates for operating the X-axis motor Mx and the Y-axis motors My1, My2, My3. As a result, the positions on the X-Y coordinates of each table are accurately set, and if drilling work is performed in this state, drilling can be performed at accurate positions.

The rotation angle correcting motors Mc1, Mc
2 and Mc3, a rotation angle correction signal is also included in addition to the positioning signal for the XY coordinates. Accordingly, if there is a shift in the rotation angle of each table, the correction is also performed, and a more accurate position can be drilled.

First, regarding the XY coordinates, the table is moved along the guides 301 and 401 by the X-axis motor Mx and the Y-axis motor My. Guide 301
Although the detailed structure of 401 and 401 is not shown, the usual X

As for the angle θ, the rotation angle correction motor Mc1
Thus, the rotation mechanism 701 attached to the back surface of the table 101 is rotated to adjust the rotation angle of the table 101.

An adjustment mechanism for such XY-θ coordinates is also provided in other tables 102 and 103.
Each adjustment can be made.
