摘要： There is provided a mounting head for an electronic component-mounting apparatus. A nozzle holder has a plurality of vacuum nozzles arranged circumferentially about an axis thereof in a manner such that each vacuum 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 axis thereof. A nozzle-rotating motor drives the nozzle holder about the axis thereof for rotation in normal and reverse directions. The nozzle holder is driven for rotation by the nozzle-rotating motor to bring one of the vacuum 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 vacuum nozzles. The cam followers are in contact with an annular end cam in a manner such that the cam flowers can move on the annular end cam. The annular end cam is formed with a nozzle-projecting surface for causing the selected one of the vacuum nozzles to project from the nozzle holder when the selected one of the vacuum nozzles is at the projecting position. A cam-rotating motor drives the end cam for rotation about an axis of the end cam in normal and reverse directions.
