Abstract There are provided a pair of concentric inner and outer annular magazines each provided with a plurality of tool pots and a blind pot which are arranged along a circle, and magazine driving device for independently rotating the outer and inner magazines to bring a tool pot containing a designated or the blind pot to predetermined tool pot indexing positions, and a tool holding pot disposed on the outside of the outer annular magazine for temporarily holding a tool taken out from one of the tool pots of the inner or outer magazine or a tool returned from a machine tool. The center of the holding pot lies on a line interconnecting the center of the inner and outer magazines and the tool pot indexing positions thereof. A saddle including a tool transfer arm with a tool gripper is moved along the line for inserting and taking out a tool into and out of a designated tool pot, and a tool exchanging mechanism is used to exchange a tool between the tool holding pot and the machine tool.
