In this invention, a component mounting machine is equipped with an image recognition device (38) for performing image recognition on a component picked up by the pickup nozzle (19), and, based on the recognition result from this image recognition device (38), the component mounting machine corrects the pickup position offset of the component picked up by the pickup nozzle (19) and mounts the component on a printed circuit board. Then, the component mounting machine assesses the state of variation in a plurality of recognition results from the image recognition device (38) (the state of variation in the amounts of component pickup position offset), and based on the assessed state of variation in the plurality of recognition results, assesses whether or not the feeder (36) and/or the pickup nozzle (19) needs maintenance. As a result, if it has been assessed that maintenance for the feeder (36) and/or the pickup nozzle (19) is necessary, an operator is notified of this through display and/or audio. |
