Patent ID: 7178225

Claim:
A component pressing device which holds a component with a component holding tool provided at one end of a shaft member, rotates the component around an axis of the shaft member and presses the component in an axial direction of the axis, so that the component is pressed against a substrate, comprising: a first voice coil motor for generating a first thrust force in the axial direction including a first coil and a first magnet movable with respect to the first coil; a second voice coil motor for generating a second thrust force in the axial direction including a second coil and a second magnet movable with respect to the second coil; a first coupling member coupling one pair of the first coil and the second coil or the first magnet and the second magnet to each other; a second coupling member coupling the other pair of the first coil and the second coil or the first magnet and the second magnet to each other; a rotational holding portion provided between the first voice coil motor and the second voice coil motor for holding the shaft member rotationally with respect to the second coupling member; a rotation-drive mechanism fixed to the first coupling member for driving the shaft member and allowing a relative displacement of the shaft member in the axial direction with respect to the first coupling member; and a guiding device for guiding the second coupling member in the axial direction with respect to the first coupling member while restricting rotation of the second coupling member around the axis with respect to the first coupling member.
