Abstract: There is provided a pitch changing apparatus which can change a pitch of DUTs when the DUTs are transferred between trays by a shuttle revolving system. The pitch changing apparatus, which changes the pitch of DUTs, includes a plurality of shuttles which hold DUTs, a first guide rail which guides the plurality of shuttles, a second feeder which feeds the shuttles along the first guide rail at a first pitch, a third feeder which includes a plurality of pins receiving the shuttles from the second feeder and moves the pins along the first guide rail at a second pitch, and a controller which controls a feed rate of the second feeder and a receiving rate of the third feeder.
