It is screwed into the Z direction feed screw 17. Z direction feed screw 17
is driven by an X-direction drive motor 18 fixed to the second movable table 15 via a belt means 19. The second movable base 15 is slidably provided on a guide bar 21 arranged in the Y direction horizontal to the third movable base 20, and is parallel to the guide bar 21 and rotatably mounted on the third movable base 20. It is screwed into a supported Y-direction feed screw 22. Y direction feed screw 22
is driven by a Y-direction drive motor 23 fixed to the third moving table 20. The third moving table 20 is provided to be slidable in the horizontal X direction on the base 24, and is driven by an X direction drive motor 25 fixed to the base 24 by an X direction feed screw (

As a result, the printing plate 2 is moved in the X direction together with the first printing plate mounting body 4. Furthermore, when the Y-direction drive motor 23 is driven, the second moving table 15 is moved in the Y-direction by the Y-direction feed screw 22.
The printing plate 2 is also moved in the Y direction. Similarly, when the X-direction drive motor 25 is driven, the third moving table 20 is moved in the X-direction, and the printing plate 2 is also moved in the X-direction.
また印刷されるワーク３０が位置決め載置されるワーク

は接点棒６は接点棒１１の下降に追従して接触を保って
下降する。With the plate 1 positioned above the workpiece 30, the Z-direction drive motor 18 is driven to lower the plate table 2. The position of the plate 1 before the start of the downward movement is stored in the main control circuit 41 in advance. The operation is performed by manually operating a well-known electric chessman (not shown) by an operator to drive the Z-direction drive motor 18 one pulse at a time. When the plate 1 descends, the contact rod 6 moves the contact rod 11 downward until the plate 1 is crushed by the weight of the plate holder 4 and the members 1 to 3.5 to 8 attached to the plate holder 4. It follows and descends while maintaining contact.
その後は版台取付体４は下降しなく、 ｗＳ１移動台９

The contact rod 11 is separated from the contact rod 6, and the contact rod 6 outputs an off signal 6a. The amount of crushing of the plate 1 described above varies depending on the material of the plate 1, but is approximately 507 zm, so taking this amount into account, the position 50 gm above the detection point is set as the Z level (distance to the surface of the workpiece 30). , This allows us to understand the distance statement between version 1 and work 30.
そこで、実際の使用においては、前記検出点から約２０

。Therefore, in actual use, approximately 20
In this way, the main control circuit 41 is programmed to rapidly lower the printing plate 2 with a search level up to 0 m (approximately 150 m from the Z level) and then lower it at a slow speed. Then, the descending time can be shortened. Further, the amount by which the printing table 2 is lowered (pushing amount) is set in advance in the main control circuit 41 based on the output of the signal 6a described above.
次に印刷動作について説明する。始動ボタンを押すと、
版台２はワーク３０の上方より前記したサーチレベル（
ワーク３０より約１５．ＯＩＬｍ上方）まで急速に下降

接触を保って下降する。Next, the printing operation will be explained. When you press the start button,
The printing table 2 is moved from above the workpiece 30 to the above-mentioned search level (
Approximately 15. (above OILm), and then descends at a slow speed. Then, the contact rod 6 follows the downward movement of the contact rod 11 and descends while maintaining contact until the plate 1 comes into contact with the workpiece 30 and the plate 1 is further crushed by the weight of the members 1 to 8.
その後は版台取付体４は下降しなく、第１移動台９のみ

付けられて捺印する。After that, the printing plate mounting body 4 does not descend, only the first moving table 9 descends, the contact rod 11 separates from the contact rod 6, and the contact rod 6 outputs an off signal 6a. In response to this detection signal, the main control circuit 41 outputs a signal to lower the plate 1 by a pre-stored pushing amount. As a result, when the first moving table 9 first descends out of the gap between the stopper 12 and the plate mounting body 4,
The stop 7 pawl 12 comes into contact with the plate base mounting body 4. Therefore, when the first moving table 9 is further lowered from this position, the stopper 1
2, the plate mounting body 4 is pushed, and the plate 1 is pressed against the workpiece 30 to make a stamp.

、均一な印刷が得られる。In this way, the Z direction drive motor 18 is driven by a certain amount from the main control circuit 41 via the Z motor control circuit 42 in response to the signal 6a, so even if there is variation in the thickness of the workpiece 30, the top surface of the workpiece 30 can be Since the amount of indentation is constant, uniform printing can be obtained.

もよい。FIG. 3 shows another embodiment of the present invention. In the embodiment described above, the contact point was detected by turning on and off the contact rods 6 and 11.
In this embodiment, the contact rods 6 and 11 are simply support rods. A non-contact type sensor 26 is fixed to the first movable base 9 with a constant gap maintained relative to the contact rod 6. That is,
A contact point can be detected by a change in the distance between the sensor 26 and the contact rod 6. Note that the sensor 26 may not correspond to the contact rod 6, but may correspond to an arbitrary position on the first plate mounting body 4.
