Paper discharge device

Provided is a paper discharge device (1) capable of securing. the sufficient length of the waiting path while achieving downsizing of the entire device, and of allowing the paper in the waiting state to wait without being brought into contact with the collected paper until the processings such as printing are ended. The paper discharge device (1) includes: a waiting path (43), one side of which is connected to the input port (40) and another side of which is connected to the discharge port (41); a collection path (44), one side of which is connected to the waiting path through a merged portion (48) and another side of which is connected to the collection chamber (47); and conveyance mechanisms (45) for conveying the paper which was conveyed through the input port until the discharge port in a forward direction, and for conveying, after lapse of a given period of time after the conveyance of the paper, the paper in a reverse direction through the merged portion to feed into the collection path, in which the waiting path is formed into a curve so that the interval between the merged portion and the discharge port is swelled downward.
