PURPOSE:To decrease a moving distance, when a workpiece is mounted and removed, and to reduce the time required for mounting and removing the workpiece, by conveying the workpiece by the cassette unit to the vicinity of a mounting and removal position so as to store the workpiece in a jig into a storage cassette while to mount the new workpiece to the jig. CONSTITUTION:A cassette 2 is fed by a cassette loader-unloader 4 to a predetermined position, and a robot moves to a cassette takeout position relocating a cassette 2, in which a finished workpiece 10 is placed, on a base 14 to the cassette loader-unloader further mounting a cassette 2, in which an unfinished workpiece 10 is placed, from the cassette loader-unloader 4 onto the base 14 of the robot. And a robot hand 9, moving to the first point where the workpiece 10 is loaded and unloaded, takes out the workpiece from a position 1a in a jig 1 to be stored in an empty cassette side. Next the unfinished workpiece is taken out from the cassette on the base 14 and mounted to the position 1a of the jig 1, further the robot moves to the second point, where the workpiece 10 is loaded and unloaded, loading and unloading the workpiece 10 in a position 1b.
