ABSTRACT:
A pusher of an IC chip handler has a pusher frame which is attached to a pusher main body to be driven by the IC chip handler and a plurality of pusher heads attached to the pusher frame. Each of the pusher heads comprises a holder which is held by the pusher frame. At least one spring post is freely protruded outward from the inside of the holder, and a compression spring has one end arranged under pressure to a spring receiving portion of the spring post. A spring push plate arranges the compression spring to the spring receiving portion of the spring post under pressure, and an adjusting member adjusts a compression force of the compression spring. A device holding unit is attached to an end of the spring post protruded outside of the holder.
