A package receiving and sorting apparatus, comprising: a stage including a work area for receiving and sorting a package; the apparatus being characterized in that it comprises: a belt configured to push the package by moving breadthways across the work area; a first holder and a second holder, which are movable such that an interval between the first holder and the second holder is variable, and between which the belt is arranged; a movement path configured to guide movement of the first holder and the second holder along a peripheral edge of the work area; an actuator configured to cause the first holder and the second holder to move; and a retractor configured to retract the belt into the first holder and the second holder, wherein the peripheral edge of the work area includes a plurality of feeding sections for feeding the package to an area outside of the work area, wherein the movement path includes: a plurality of delivery sections, where each of the plurality of delivery sections is adjacent to one of the plurality of feeding sections; a pair of final positions, at which the first holder and the second holder are positioned, respectively, when feeding of the package is complete; and a pair of midway positions, at which the first holder and the second holder are positioned, respectively, in a middle of feeding of the package, wherein the pair of final positions are arranged at both sides of a selected one of the plurality of delivery sections along the movement path, wherein the pair of midway positions are located further away from each other than the pair of final positions along the movement path, wherein, when the first holder and the second holder are positioned at the pair of midway positions, the belt is arranged between the first holder and the second holder so as to cross the work area, and the package is positioned between the belt and the selected one of the plurality of delivery sections, wherein the first holder and the second holder are configured to come closer to each other when approaching the pair of final positions from the pair of midway positions, and wherein the belt is configured to pull the package in a direction of the selected one of the plurality of delivery sections by being retracted into the first holder and the second holder by the retractor. a stage including a work area for receiving and sorting a package;
