Abstract
In a case where a vacant space exists on only one side in a holder area of a stocker positioned at an exchange position, a first upper tool exchange unit is first moved in the left-right direction, and located in the vicinity of the vacant space. Next, the first upper tool exchange unit is moved forward and thereafter moved to the left, so that a tool retention member of the first upper tool exchange unit is brought into contact with one side surface of a tool. Then, under the contact state, the first upper tool exchange unit is moved to the right until the other side surface of the tool abuts on a stopper.
