Compact sorter for a copy machine

A compact sorter for a copy machine comprising a rotatable transfer wheel which has a radius of gyration, an ejecting section for ejecting copies, a slot liner having first and second vertical portions connected by a middle portion which extends relative to the vertical portions toward the ejecting section in the radius of gyration of the transfer wheel, and a plurality of bin trays each capable of moving along the slot liner toward the ejecting section for receiving the copies, characterized by:

• each said bin tray having a pair of space controlling cams which comprise upper and lower space controlling arms and are symmetrically provided at both side outer ends of said bin tray for maintaining predetermined upper and lower spaces with additional upper and lower bin trays during movement for receiving copy from said ejecting section, said upper space controlling arm having a triangular shape with one side relatively longer than the other sides, said upper space controlling arm having a flap extending outward for preventing rightward and leftward movement of said bin tray, said lower space controlling arm having a lowerward protruding arm portion extending from the front end of said space controlling cam, the middle portion of the slot liner comprising a first part upwardly sloping toward the ejecting section and a second part upwardly sloping away from the ejecting section, and a plurality of bin trays each capable of moving along the slot liner toward the ejecting section for receiving the copies, and said first part of the middle portion of the slot liner comprising first and second bending parts for minimizing an interference between cams of an upward moving bin tray and a lower bin tray.
