Abstract
A bonding apparatus with an optical detecting device that detects any positional discrepancy between first and second parts which are to be bonded together, the optical detecting device including an optical probe that comprises: first and second image acquisition prisms which respectively reflect, in different directions, first and second images of the first and second parts respectively; a first optical system introduction prism (or mirrors) which causes the first image of the first part that passes through the first image acquisition prism to be reflected an even number of times and then sends this first image to a first image pick-up device through a first focusing device; and a second optical system introduction prism which causes the second image of the second part that passes through the second image acquisition prism to be reflected an odd number of times and then sends this second image to a second image pick-up device through a second focusing device.
