A belt system is disclosed for transferring a data carrier between a magazine and a data reader for use in a data carrier loader of the type wherein the data reader is moved, within the loader housing, over the stationary magazine in the housing to transfer a data carrier therebetween. The belt system includes two belt assemblies, which are carried on the data reader and which are disposed for engaging opposite lateral sides of a data carrier in the magazine. A mechanical linkage is provided for moving the assemblies toward and away from the lateral sides of the data carrier, the linkage being a reciprocating linkage which can be moved in either direction by means of an internally threaded element, which engages a pivotable element of the linkage, the internally threaded element being moved by a rotating threaded rod received therein. When the belt assemblies engage the data carrier, the belt is rotated in a selected direction either to lift the data carrier from the magazine into the reader or to remove the data carrier from the reader and replace it in the magazine. <IMAGE> |
