ABSTRACT:
An apparatus for printing not only embossing braille characters but also an embossing figure on a recording medium such as paper, using a projection of a rod employed as a debossing die and a printing underlay employed as an embossing die. The printing underlay includes at least one elastic layer. The apparatus includes an element to stop a depressing depth of the projection into the printing underlay so that the depressing depth is uniform. The element to stop the depressing depth of the projection into the printing underlay may include a step formed on a part of a periphery of the printing rod, and additionally a stopping wall whereby the depressing depth of the projection into the printing underlay is stopped by the step knocking against the stepping wall. Different projections with different step positions may also be provided.
