  • Patent number: 5876128
    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.

  • Patent number: 5456632
    Abstract: An external memory apparatus for an information recording and play-back device, with the external memory apparatus having an improved cooling arrangement. In particular, a cooling fan is disposed inside of the housing, at a location spaced from a wall of the housing, with an exhaust outlet provided having a smaller area than that of the cooling fan. The exhaust outlet is preferably connected to the cooling fan by a duct, with the cooling system allowing the overall size of the external memory apparatus to be minimized.
