ABSTRACT:
The connecting element inspecting method inspects a connector having a connecting surface to another connector paired with the connecting element and a plurality of terminal containing holes opening to the connecting surface for respectively containing terminals. The connecting surface is irradiated by light entering the terminal containing holes. The connecting surface is imaged obliquely from a television camera. The percentage of the area of a portion occupied by the terminal in an image region associated with the terminal containing hole to be inspected is found. It is judged whether or not the terminal is properly mounted in the terminal containing hole to be inspected on the basis of the found percentage of the area. Consequently, it is judged whether the connector is accepted or rejected.
