PROBLEM TO BE SOLVED: To obtain component height measuring method and apparatus in light weight and low price component mounting apparatus which uses a component suction nozzle for actually sucking components to measure height of components with higher accuracy including fluctuation of the component suction nozzle itself. SOLUTION: The component height measuring apparatus 1 in the component mounting apparatus comprise a vacuum/positive pressure supply source which also operates as a component suction nozzle 2, a vacuum/positive pressure switching electromagnetic valve provided between the vacuum/positive pressure supply source and component suction nozzle, an air-pressure or air-flow detecting means provided between the vacuum/positive pressure switching electromagnetic valve and component suction nozzle and a calculating means for calculating height of component based on the result of detection by the air-pressure or air-flow detecting means. |
