• a loading line induction putting parcels supplied by the loading line to the track;
• carriers disposed on the track and moved by operation of the track with the parcels thereon which have been put in;
• a plurality of chutes disposed along the track so that the parcels on the track are discharged by the same destination groups;
• a 5-face image processor disposed at a side of the track, reading out parcel information marked on the top and sides of parcels, and sensing the positions of parcels on the track;
• a feedback line putting parcels not read out by the 5-face image processor back to the track;
• and
• a controller determining chutes for discharging parcels using the parcel information transmitted from the 5-face image processor,
• wherein the track includes a pair of first and second tracks provided to handle parcels for a first area with a density of parcel and a second area with a density of parcel less than the first area, respectively, and
• the parcel sorting system further comprises:
• a shortcut line connecting the first and second tracks so that parcels, which are not parcels for a corresponding area and have been put in wrong, can be conveyed to a corresponding track;
