To provide a component-mounting machine (1) which prevents collision of a sucked component (PA) with an optical system capturing images of an imaging reference mark (5M) and the sucked component (PA) simultaneously when a component-mounting head (52) moves to capture images while lightening the component-mounting head (52). In the component-mounting machine (1) of the present invention, a sucked-component position detection device (6) includes an imaging unit (61), which is installed on a side of a base 8 (a side of the direction indicated by arrow Z1) of the component-mounting machine (1) and has an image sensor (611) and a lens (612); and a first refraction member (62) which alters a focal position (FP1) of a first optical path OP1 that connects the image sensor (611), the lens (612) and the imaging reference mark (5M). The first refraction member (62) is installed on the side of the base (8) (a side of the direction indicated by arrow Z1) and at a position lower than a focal position (FP2) of a second optical path (OP2) that connects the image sensor (611), the lens (612) and the sucked component (PA) . |
