Paper discharging apparatus for printer

A paper discharging apparatus for a printer, comprising:

• a plurality of support plates for supporting the paper, said support plates being installed on both sides of a paper proceeding direction on a base frame and rotating in a direction parallel to the paper proceeding direction;
• a rotation shaft of a feed roller disposed in a direction perpendicular to the paper proceeding direction, said feed roller contacting the paper and being coupled to said rotation shaft;
• a power transfer portion having a sector gear installed on the rotation shaft so that the sector gear does not rotate when the rotation shaft rotates in a forward direction and rotates when the rotation shaft rotates in a reverse direction;
• a crank rod having an end connected to the sector gear and reciprocating when the sector gear rotates;
• a cam shaft connected to the crank rod and rotating in correspondence to the reciprocation of the crank rod, and connected to a cam for performing interference movement relative to the support plates;
• and
• a holder rotatably engaged with the cam shaft and having a plurality of kickers for pushing the paper toward the support plates;
• wherein the power transfer portion further comprises:
• a discharge gear coupled to the rotation shaft of the feed roller;
• a plurality of idle gears rotating by being engaged with the discharge gear;
• and
• a toggle plate to which the idle gears are installed, and having a through hole formed therein and through which the rotation shaft of the feed roller passes.
