Stamp with inking pad - prints set of axes with scale markings for educational use

摘要

The stamp with inking pad is designed to print part of a set of axes with scale markings. The axes can be in a cruciform or L-shaped pattern, and the stamp can have positioning devices in the form of pointed needles protruding from the working face and pressed into it by finger pressure. The needles can be spring-loaded, and extended and retracted by a press-button and locking mechanism. The inking pad (6) can be of shape corresponding to that of the stamp (1).
