Authors have been promoting development of the automatic carrier to which a linear induction motor is applied for the past several years. A new method for stopping a chassis at designated position has been proposed by authors so far. The strong point of this stop method is to be able to stop automatically a chassis by non-contact and no vibration. In this paper, we describe an automatic operation system of this carrier : we show a design of a control unit of a sequence method ,its product, and experimental results of an automatic run and automatic stop of a chassis by the control unit.
