PURPOSE:To make it possible to store many tools without their mutual interference by providing a cam groove for guiding the tools around a tool magazine and allowing the cam groove to project from the external periphery only at an exchange position. CONSTITUTION:A tool magazine 10 is provided with a fixed shaft 12, around which a tool magazine rotary part 14 is provided. On the external periphery of the annular tool magazine rotary part 14, the plural number of shaft levers 16 radially extend with an approximately equal interval, and are mounted and fixed. On the tip of the shaft lever 16 a sliding sleeve 20 slidable to the shaft lever 16 is provided, and the cam follower 26 of the sleeve 20 travels along an endless cam groove 28. When the rotary part 14 of the tool magazine is turned, only a required tool is projected at a part 28a having a small radius of curvature protruding at an exchange position. |
