Abstract
A mounting head includes a pickup nozzle, a shaft member, a drive unit, and a position retainer. The shaft member has a cylindrical shape and moves in an axial direction to switch a pressure applied to the pickup nozzle between negative and positive pressures. First and second movement ends in the axial direction are negative and positive pressure application positions, respectively, where negative and positive pressure, respectively, is applied to the pickup nozzle. The drive unit includes a drive source that moves a movable portion in the axial direction. The movable portion contacts the shaft member when moved in the axial direction, to move the shaft member between the negative and positive pressure application positions. During a power-off period of the drive source, the position retainer holds the movable portion in a predetermined position away from the shaft member located at the negative or positive pressure application positions.
