Claim Text:
1. A component-mounting machine, comprising: a component-mounting head that includes a suction nozzle which sucks a component to mount on a substrate and includes an imaging reference mark; and a sucked-component position detection device which captures images of the imaging reference mark and the sucked component sucked by the suction nozzle simultaneously to detect a position of the sucked component with respect to the imaging reference mark, wherein the sucked-component position detection device includes an imaging unit which is provided on a base side of the component-mounting machine and has an image sensor and a lens; and a first refraction member which alters a focal position of a first optical path that connects the image sensor, the lens and the imaging reference mark, the first refraction member is provided on the base side and at a position lower than a focal position of a second optical path that connects the image sensor, the lens, and the sucked component, and the imaging reference mark is higher than the sucked component in a height direction of the component-mounting head.
