Claim:
A paper discharge unit used with an inkjet printer which ejects a sheet of paper, on which image printing is completed by an ink cartridge having a nozzle part, out of a printer main body including an internal wall comprising a slit, comprising: a paper discharge roller rotatably mounted in the printer main body, to feed the sheet out of the printer main body; a paper discharge guide disposed between the paper discharge roller and a paper discharge opening which is formed in one side of the printer main body; and a driving unit to move the paper discharge guide to guide a front end of the sheet upward just after the front end is ejected from the paper discharge roller so as to prevent a rear end portion of the sheet from being lifted toward the nozzle part of the ink cartridge, the driving unit comprising a protrusion received by the slit which thereby guides the protrusion, a range of movement of the driving unit being limited by the protrusion and the slit.
