Abstract
A pick-up head module has two vertical tubes for picking up small objects such as ICs by suction. A mechanism is provided for rotating these two tubes around their own axes. The tubes are individually supported by two separate tables, one (first) rack gear being attached to one of these tables and two (second and third) rack gears being attached to the other. These three rack gears are all vertically oriented, the first and second rack gears being in a side-by-side relationship and the third rack gear being opposite therefrom. A pinion is provided so as to be controllably slidable in the direction of its axis, thereby selectably engaging either with the first and second rack gears or with the first and third gear.
