Abstract: A memory device memorizes a link between an orientation of a leaded component supported on a component support section and a type of component holding tool used for holding the leaded component of the orientation is memorized in a memory device. Also, the component support section on which multiple leaded components are scattered is imaged by an imaging device, and orientations of leaded components supported on the component support section are identified based on the captured image data. Then, the component holding tool of a type memorized as being linked to the identified orientation of leaded component is decided as the component holding tool for holding the leaded component. By this, it is possible to exchange a component holding tool according to an orientation of a leaded component, thus it is possible to hold leaded components of various orientations using component holding tools.
