An overprint stamper is provided with three print surface retainer portions positioned flush with each other in the non-depressed condition, print surface portions each comprising a thermoplastic expanded sheet fixed to each print surface retainer portion, a slider portion for supporting the print surface retainer portions rotatably by means of a resilient hinge means while being generally movable, and a guide bar for guiding the direction in which the slider portion moves. Further, in order to control the position where the slider portion stops so that each print surface portion is positioned at a predetermined printing position, three grooves are provided on the guide bar and a spring having a protrusion fitting therein is fixed to the slider portion.
