The following is known as such an automatic stamping device.

A marking device disclosed in Japanese Patent Application Laid-Open No. 60-183148 discloses a "marker having a marking head having a resiliently vertically moving stamping head having a mark attached thereto, which fluctuates due to a thickness variation of a body to be marked. The amount of movement is set so that the mark is located below the lowermost limit of the surface ", and even if the articles have different heights to the surface to be marked, the mark can be clearly displayed.

The printing method and apparatus disclosed in Japanese Patent Application Laid-Open Nos. 62-286786 and 62-288038 make use of an offset roll rotating in contact with a plate cylinder against a running web. By printing on the web and changing the peripheral speed of the plate cylinder and the traveling speed of the traveling web, the repeat length of the print pattern can be changed, and the repeat length can be changed without substantially changing the diameter of the plate cylinder. It can be different. Ink is applied to the plate cylinder from a pumping roll for transferring ink via a transfer roll, and the peripheral speed of the transfer roll is adjusted to adjust the amount of ink applied from the transfer roll to the stamp of the plate cylinder. .

The automatic marking device disclosed in Japanese Patent Application Laid-Open No. Hei 7-290808 has an elastic roller that rotates while applying contact with a printing plate transferred by a rotating drum to apply ink to the printing plate. An ink replenishment roller that is supported so as to be able to contact and separate from the elastic roller, rotates while contacting the elastic roller when supplying ink, and supplies ink to the elastic roller. Is prevented.

The ink roller mechanism includes a “ink applying member for applying predetermined ink to the stamping roller, a spring member for normally urging the ink applying member to be separated from the stamping roller, and a spring member. And a cam member for bringing the ink application member into contact with the stamping roller against the spring force, ''
The position accuracy of imprinting has also been significantly improved, and high-speed imprinting is possible while maintaining high imprinting quality. The ink application member comes into contact with and comes into contact with the imprint roller with the rotation of the cam member only when ink is applied.

[0011]

However, in the ink roller unit 1 of the conventional automatic stamping device, the ink roller 3 for applying ink to the seal surface 2a of the seal roller 2 is located at a predetermined position. Adjustment is not possible after fixing, and it is possible to obtain a dark imprint when the ink roller 3 is replaced, but it gradually becomes thinner as the ink roller 3 is used. Then, it becomes impossible to obtain a sufficient imprint. Further, when the seal surface 2a and the surface of the ink roller 3 on which the ink is applied are not parallel due to a change due to the mounting state or use of the ink roller 3, the ink roller 3
However, it is not possible to obtain an accurate imprint, for example, such that one side of the imprint is dark and the other is light, for example.

The same applies to a marking device, a printing method and device, an automatic marking device, and a stamping device. That is, in the case of a marking device, a mark portion having a marking head moves in accordance with the thickness of a body to be marked (thickness of paper or the like), and in the case of a printing method and device, the peripheral speed of a transfer roll is adjusted. In the case of an automatic marking device, the amount of ink applied on the transfer roll is adjusted, and the ink supply roller is supported so as to be able to contact and separate from an elastic roller (ink pat roller), but applies ink to the printing drum. The elastic roller does not move, and in the case of the stamping device, the ink applying member approaches and comes into contact with the stamping roller with the rotation of the cam member only during ink application. It is not possible to adjust the state of contact with the stamp surface to be transferred.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic stamping device which can adjust the contact state of an ink applying member to a seal surface and can always stamp an accurate stamp.

[0014]

In order to achieve the above object, an automatic stamping apparatus according to the present invention presses a seal surface of a seal roller coated with ink by an ink roller against a sheet to transfer a seal to the sheet. In the automatic stamping device, the pressing state between the ink roller and the seal surface can be adjusted.

With this automatic stamping device, it is possible to adjust the stamp surface of the stamp roller and the pressing state of the ink roller for applying ink to the stamp surface, and to maintain the positional relationship between the ink roller and the stamp surface in an appropriate state. It is possible to always imprint an accurate imprint.
