1. A tracing device comprising:
a central processing unit (CPU) configured to
determine whether an image processing, which is executed in a production process of a board product by a board work machine, satisfies an appropriateness condition indicating reliability of a result of the image processing when the result of the image processing stays within a permissible range in which the result of the image processing is determined normal; and
record image data used in the image processing as traceability information according to a result of the determination,
wherein the image processing includes a primary image processing using the image data acquired by a first camera that images a constituent component from a first direction, the constituent component making up the board product, and a secondary image processing executed for secondary image data for the same constituent component after the primary image processing, the secondary image data being acquired by a second camera that images the constituent component from a second direction that is substantially perpendicular to the first direction.
