Stamp and process for mounting a stamp plate

The invention relates to a stamp comprising a telescoping upper and lower part as well as a printing plate holder pivotally disposed in the lower part to accommodate the stamp plate. A retaining device for a stamp pad is associated with the printing plate holder, and in a rest position the printing plate holder is positioned in the range 80° to 135°, preferably at approximately 90° with respect to a contact area. From this rest position the stamp can be displaced into an operating position to produce a stamped imprint via guide means, whereby the printing plate holder is turned about two guide pins, wherein one guide pin is respectively disposed on a side face of the printing plate holder, and the guide pins simultaneously engage in guide slots in the upper and lower part.
