ABSTRACT:
There is provided a mounting head for an electronic component-mounting apparatus. A nozzle holder has a plurality of suction nozzles arranged circumferentially about a vertical axis thereof in a manner such that each suction nozzle is capable of projecting from the nozzle holder and retracting in the nozzle holder. A holder support member supports the nozzle holder in a manner such that the nozzle holder can rotate about the vertical axis thereof. Rotation drive means drives the nozzle holder for rotation in normal and reverse directions. The nozzle holder is driven for rotation by the rotation drive means to bring one of the suction nozzles selected for use to a projecting position. The selected one is caused to project from a lower end face of the nozzle holder at the projecting position. A plurality of cam followers are mounted at respective upper portions of the suction nozzles. The cam followers are in contact with an annular end cam in a manner such that the cam flower can move on the annular end cam. The annular end cam is formed with a nozzle-projecting surface for causing one of the suction nozzles corresponding in position thereto to project from the nozzle holder.
