APPARATUS FOR SUPPORTING FEEDING ROLLER SHAFT OF INK JET PRINTER

摘要

PURPOSE: A feeding roller shaft supporting apparatus for an ink jet printer is provided to improve resolution of a printing object by preventing a printing paper from being biased due to a movement of a feeding roller shaft. CONSTITUTION: First to third fixing pieces(11,12,13) are aligned in a main chassis(10) while being spaced from each other by a predetermined distance. A feeding roller shaft(20) is rotatably inserted into the first and second fixing pieces(11,12) by interposing a first supporting member. A driving gear(22) is coupled to one side of the feeding roller shaft(20). An axial direction position correcting unit(23) is coupled to the other side of the feeding roller shaft(20) so as to correct an axial position of the feeding roller shaft(20) when the feeding roller shaft(20) is rotated. The first support member includes a first busing for supporting one end of a coupling section of the driving gear(22) and a second bushing for supporting the other end of the coupling section of the driving gear(22).
