A slider is associated with a carrier for transferring a vehicle body through a magnet and an air cylinder. An amount or a distance of movement of the slider transferred together with movement of the carrier is detected with a rotary encoder and it is computed as an amount or a distance of movement of the carrier. When the carrier is transferred in a predetermined amount or distance, an image of the vehicle body is fetched by an investigating robot. The fetching does not undergo any adverse influence due to a deviation of the position of the investigating robot relative to the position of the carrier.
