Abstract
A contact state detection apparatus which can accurately detect the pressed state of a contact body such as a probe against an object without damaging the contact body or the object includes a contact body approach section, a probe light source, an imaging device, and a computer unit. The contact body approach section holds a contact body in an inclined attitude with respect to a target contact surface of an object, and displaces the contact body toward the object. The probe light source irradiates light toward the contact body which is being displaced toward the object. The imaging device captures an image of the illuminated contact body and outputs contact body captured image information to the computer unit. The computer unit detects the state of the contact body being pressed against the object based on a change in the contact body captured image information.
