Abstract
A component recognizing method, and an apparatus for executing the method, for applying light to leads on a mounting surface of an electronic component and executing positional detection of the leads by a height detecting section, comprising a 3-D sensor, on the basis of light reflected from the leads. The method includes limiting a region to be measured by the height detection section so that light reflected from objects behind or near the leads is excluded from the region and processing light reflected from the region, thereby removing the reflected light from objects behind or near the lead.
