<p>PURPOSE:To adjust a distance between main feed and subfeed rollers by mounting them to a feed roller shaft formed hollow, fitting into the feed roller shaft a core shaft possible to interlock to the subfeed roller and providing an adjusting mechanism of the core shaft on the outer end of the feed roller shaft. CONSTITUTION:A plurality of main feed and subfeed rollers 14, 15 are mounted with a predetermined space to a feed roller shaft 10 formed into a hollow shape, and its inside slidably fits a core shaft 17 in a direction of the axial line, while the subfeed roller 15 is slidably fitted by connecting it to the core shaft 17 through a long hole provided in the feed roller shaft 10. While thread adjusting mechanism 20, 21, which can adjust a position of the subfeed roller 15 in its axial line direction by sliding the core shaft 17, are provided in an outer end part of the feed roller shaft 10. Thus, because a distance between the main feed and subfeed rollers 14, 15 can be arbitrarily adjusted, a paper form can adjust in its posture according to the arbitrary paper form.</p> |
