Abstract
A component mounting device includes multiple selector valves corresponding individually to multiple holders disposed on a rotary head and switching between making and breaking communication between a corresponding holder flow path and a negative pressure source, and valve driving devices driving selector valves corresponding to holders, among the multiple holders, located in predetermined revolving positions. The component mounting device executes a negative pressure recovery operation when a suction error has occurred in which the component is not held by suction to the nozzle after suction operation. When a suction error occurs at the nozzle held by the holder, the component mounting device performs the negative pressure recovery operation by waiting for the holder to be rotated to a predetermined revolving position and drives the selector valve corresponding to the holder using the valve driving device to cut off communication between the holder flow path and the negative pressure source.
