<p>For determining the types of component holding members equipped to a plurality of holding-member equipping sections, a detection sensor having a detection optical axis in a direction intersecting with the arrayed direction of the respective holding-member equipping sections is used, and the respective holding-member equipping sections have a first detection position where interrupting of the detection optical axis is detectable only when a second component holding member is equipped and a second detection position where interrupting of the detection optical axis is detectable when the component holding member of any type is equipped. Consequently, by sequentially positioning the detection optical axis at the respective detection positions and detecting the presence of interrupting, the type of the equipped component holding member is determined only by the detection sensor.</p> |
