ABSTRACT:
A wire bonder50in which light rays66that leave an object on a carrying stand60pass through a light path80that passes through a parallel flat plate and reach an imaging camera70as light rays68. The light path80that passes through a parallel flat plate includes a half-mirror82disposed in the light path, a parallel flat plate86, and a reflective mirror88which is disposed perpendicular to the optical axis of the light rays96that have passed through the parallel flat plate86and which performs a mirror reflection operation, in a plane perpendicular to the optical axis, on the light rays96, so that the light rays again return to the parallel flat plate86as reflected light98.
