This invention enables the designation of alternative nozzle along with the designation of recommended nozzle. Also, this invention enables the independent set-up and registration of the data on the control during component handling for each nozzle. When both the first and second preferred nozzles are set up as valid, and both nozzles are stored in the nozzle stocker (17), the replacement with the recommended nozzle stored in the stocker (17) is made and the CPU (20) controls the operation based on the "control data (the first preferred nozzle)". When both are set up as valid, but only the second preferred nozzle, not the first preferred nozzle, is stored in the stocker (17), the CPU (20) recognizes which nozzle is available by using the nozzle positioning data stored in RAM (22), and then the replacement with the alternative nozzle (the second preferred nozzle) is made, and the CPU (20) controls the operation according to the "control data (the second preferred nozzle)" of the alternative nozzle. <IMAGE> |
