Abstract

A paper discharging apparatus for a printer includes: a plurality of support plates for supporting the paper and rotating in a direction parallel to a paper proceeding direction; a rotation shaft of a feed roller arranged in a direction perpendicular to the paper proceeding direction, and to which a feed roller contacting the paper is coupled; a power transfer portion having a sector gear installed on the rotation shaft so that the sector gear doe not rotate when the rotation shaft rotates in a forward direction, and the sector gear does rotate when the rotation shaft rotates in a reverse direction; a crank rod having one end connected to the sector gear, and reciprocating when the sector gear rotates; and a cam shaft connected to the crank rod and rotating in correspondence to the reciprocation of the crank rod. A cam for performing interference movement relative to the support plates, and a holder engaged with the rotation of the cam shaft and having a plurality of kickers for pushing the paper toward the support plate, are also provided. When the sector gear rotates in a forward direction, the paper is supplied or printed; when the sector gear rotates in a reverse direction, the holder is engaged with the cam shaft to perform angular movement by means of the crank rod connected to the sector gear so that an end portion of the paper is pushed. The paper is supported by the support plates, and is dropped downward and stacked. Thus, by using a power transfer portion having a simple structure, cost can be reduced and printing speed can be improved. Also, by using a crank rod and a cam shaft, discharged paper can be stably stacked without being damaged so that the paper can be stably discharged from the printer.
