Abstract
A recording paper transportation path structure suppresses sagging of the recording paper fed from the nipping part of a pair of rollers to the platen surface of a vacuum platen, and can prevent a drop in paper feed precision. In a roll paper printer, the recording paper fed through the nipping partof a paper feed rollerand a paper pressure rolleris fed along the contact plane Pof the outside surface of the rollersandtoward the platen surfaceof the vacuum platenat a slightly lower position. An inclined surface partthat slopes along the contact plane P, an up-lifting surface partthat slopes down, and a protruding surface partare formed contiguously to the upstream side at the upstream end partof the platen surface. Because the part of the recording mediumfed from the nipping partis supported and guided by these parts, the paper is guided to the horizontal surfaceof the platen surfacewithout drooping down, and a drop in paper feed precision and paper jams caused by the recording paper sagging can be avoided.
