An apparatus includes: a retainer moving between a shuttle and a socket; a presser holding a component; an adjuster moving the presser; a socket mark near the socket; a hand mark near the socket mark when the retainer is at a component mounting position; a first camera photographing a first image including the component and hand mark; a second camera photographing a second image including the socket mark and socket, and a third image including the socket mark and hand mark; a first calculator obtaining a first relative position between the socket mark and socket from the second image; a second calculator obtaining a second relative position between the socket mark and hand mark from the third image; and a third calculator obtaining a third relative position between the hand mark and component from the first image. The adjuster corrects the component's position based on the relative positions.
