Abstract
A component mounting apparatus and method allows for components supplied from component supplying members to be simultaneously or continuously held by component holding members without being affected by positional displacements of the component holding members relative to a head, a positional displacement of the component supplying members or the like. With a positional displacement amount (Δy) along a Y direction relative to a reference position of a nozzle taken into account, at a component supply cassette, driving a motor for moving components one by one along the Y direction to a component supply position is controlled, thereby positionally adjusting a component at the component supply position and absorbing the positional displacement amount.
