<p>An environmentally insensitive device is described. The device uses a passive paper guide to direct an output paper stream from a paper source (56) contained within the unit (10) to an output aperture (14). The passive paper guide uses two opposing surfaces (36,38) to define a radius (R) of curvature through which the paper strip (30) is guided. Use of longitudinal ridges (40,68) along one or both of the surfaces reduces friction along the guide. By providing a rotatable output cover (16) over the aperture (14) and using a unit cover (12), a printed output can be achieved while maintaining the shielding of the unit from environmental effects. <IMAGE></p> |
