Claim Text:
1. A workpiece conveying device for conveying a workpiece, comprising: a workpiece holding mechanism configured to operate so as to hold and release the workpiece; an actuator equipped with a movable member directly or indirectly connected to the workpiece holding mechanism in order to drive the workpiece holding mechanism over a movable range; and a stopper device having a male member and a female member, at least one of the male member and the female member having a stopper surface, the stopper surface limiting the movable range of the workpiece holding mechanism when the stopper surface contacts with the workpiece holding mechanism, wherein the male member and the female member are configured to engage with each other in at least a first arrangement and a second arrangement, wherein in the first arrangement, the stopper surface limits the movable range of the workpiece holding mechanism to a first end position such that when the workpiece holding mechanism is moved to the first end position and contacts the stopper surface, the workpiece holding mechanism is in a first predefined discontinuous holding position, and wherein in the second arrangement, the stopper surface limits the movable range of the workpiece holding mechanism to a second end position that is different from the first end position such that when the workpiece holding mechanism is moved to the second end position and contacts the stopper surface, the workpiece holding mechanism is in a second predefined discontinuous holding position.
