An article bagging apparatus designed to reduce impacts caused by stopping at advance and retraction terminal points. The article bagging apparatus has an upper scoop (12) and a lower scoop (14) rectilinearly movable forward and backward together. The upper and lower scoops are advanced and inserted into a bag through an opening thereof, and the upper scoop is displaced upward, thereby expanding the bag vertically. In addition, the upper and lower scoops are retracted to pull the expanded bag, thereby allowing an article placed in the path of retraction to enter the bag. The article bagging apparatus includes a coupling unit (22) that allows the upper scoop to be displaced vertically and that causes the upper and lower scoops to move together forward and backward, an upper guide rail (24) supporting the upper scoop horizontally movably, and an upper drive unit (26) vertically moving the upper guide rail.
