Abstract:
1. A method, for a component mounting head having holding-member equipping sections which are arrayed in a line and to each of which a first component holding member or a second component holding member having a shape different from that of the first component holding member can be replaceably and selectively equipped so as to hold a component and mount the component on a circuit board, for determining a presence of equipped first or second component holding members equipped to corresponding holding-member equipping sections, the method comprising: determining whether an interruption of a detection optical axis of a detection sensor exists with respect to a corresponding holding-member equipping section, the interruption being caused by one of the first and second component holding members being equipped to the corresponding holding-member equipping section, by (i) positioning the component mounting head such that the corresponding holding-member equipping section is arranged at a first detecting position, or by (ii) positioning the component mounting head such that the corresponding holding-member equipping section is arranged at the first detecting position and then positioning the component mounting head such that the corresponding holding-member equipping section is arranged at a second detecting position, wherein the detection sensor is arranged such that the detection optical axis is disposed in a direction that is transverse with respect to a direction in which the holding-member equipping sections are arrayed, wherein the first detecting position is a position at which an equipped first component holding member will not interrupt the detection optical axis and at which an equipped second component holding member will interrupt the detection optical axis, and wherein the second detecting position is a position at which either an equipped first component holding member or an equipped second component holding member will interrupt the detection optical axis; and determining whether a first or second component holding member is equipped to the corresponding holding-member equipping section based on a detection result obtained from said determining of whether an interruption of the optical axis exists with respect to the corresponding holding-member equipping section.
