Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is an improvement to stamps that are used by pre-penetrating and impregnating ink into a porous stamp material. Regarding creation.

0002

[Conventional technology]

This type of stamp does not require refilling the ink each time, but due to its nature, the stamp material is soft. If the stamping pressure is too strong, the stamp material will be crushed and excess ink will flow out, making the stamp impression unclear. There was a risk that it would become obvious. Therefore, in this type of stamp, there is a slide that slides around the stamp material and against the stamp body. An auxiliary force that fits around the cylinder and that should always protrude downward from the stamp surface of the stamp material against this slide cylinder. The system adopts a structure that gives subtle feedback to the stamper and controls the stamping force. was used.

0003 However, the thickness of the stamp material for this type of stamp often varies, and as a result, The protrusion limit position of the slide tube from the stamp surface is not constant, and there are some issues that should be given to the stamper. There was a problem in that the response to the product differed depending on the product.

0004 Therefore, the method described in Utility Model Application Publication No. 63-139963 and Utility Model Application No. 63-139963 The conventional method is to finely adjust the protrusion limit position of the slide tube using an adjusting member. It had been proposed in the past.
