Patent ID: 6876761

Claim:
A calibration jig for a component recognition device to be used in making a coordinate system within a view field of the component recognition device provided for confirming an attitude of a component before the component is mounted to a to-be-mounted object; and agreement with a coordinate system of a component holding device for holding and mounting the component to the object, said calibration jig comprising: a plate having a flat face for reflecting light to be received by the component recognition device, and a recognition part for obtaining a point on the flat face, said recognition part being located at the flat face, and the point being necessary for confirming the agreement of the coordinate systems, said recognition part being arranged within a periphery of the flat face, and having a light reflectance that is different from that of the flat face; and a reinforcing member for reinforcing said plate, said reinforcing member being disposed at an opposite face of said plate relative to the flat face, said recognition part comprising an opening formed in the flat face, wherein said reinforcing member has a recessed part that is formed so as to correspond to the opening; the recessed part permitting the component recognition device to recognize a clear outline of the opening, and wherein the recessed part of the reinforcing member has an inner face that is dark or colored black in order to suppress the reflection of light.
