PURPOSE:To facilitate positioning to a tool conveyor truck, by enabling the adjustment of the position of a sprocket near a tool exchange position. CONSTITUTION:Since the position of a support shaft 19 for a sprocket 11 near the tool exchange position A of a chain-type tool magazine 8 is adjustable upward, downward, rightward and leftward, the tool exchange position can be adjusted to a workpiece conveyor truck 29 without alterating the setting of a machine tool 1. The change in the tension of a chain which results from the displacement of the sprocket 11 can be compensated by a chain tightener 14. |
