Zusammenfassung:	In an indexing control device for a tool storage magazine having a plurality of index positions, each of which has a specific decimal number coded by binary coded decimal elements, the tool storage magazine is divided into a plurality of regions by means of the upper figures of the decimal numbers. The index control device comprises first and second discriminating circuit means, one of which selects the rotating direction of the magazine in to index the region including the desired index position to a predetermined position in a shorter route by means of the upper figure, and the other of which selects the rotating direction to index the desired index position to the predetermined position in a shorter route by means of the subordinate figure of the decimal number after indexing of the region.
