A transfer wheel of a sorter for transferring bin trays, each have a pair of pin trays, sequentially, comprises a transfer wheel body having three slots arranged at 120 degree angles around a central rotating shaft hole of the transfer wheel, and having a guide portion for guiding the pin trays of the bin tray. The transfer wheel also includes three pairs of insert wheels, each pair comprising two types of insert wheels mounted adjacent each other, between the slots in order to alternatively lift and push the pin tray to move the slot liner of a side plate. Further included is a mounting arrangement for mounting the insert wheels on the wheel body, and driving arrangement for rotating the wheel body. The invention provides a quiet transfer wheel which separates copies at every one-third rotation of the wheel, which causes an upper and a lower waiting pin tray to be positioned within the radius of rotation of the wheel. The invention uses either a rack style, a wire style, or a spring style device to support the bin tray.
