ABSTRACT:
The present invention provides a device and a method for determining whether or not a component holder is good, which enable detecting component holders that are to affect correct component recognition and further enable preventing interferences between constituent devices, a component mounting apparatus with the determining device, and a component mounting method. The determining device has an illuminating device, a CCD camera and a controller to determine whether or not a suction nozzle is good based on luminance at a component hold face of the suction nozzle. The suction nozzle having light reflectance of the component hold face increased to a level whereat a correct recognition of an electronic component held by the suction nozzle is affected, can be detected accordingly. An interference preventing device is also provided, so that interference between the CCD camera and the suction nozzle can be prevented.
