A compact flat type vibrator motor is provided in which movement of the center is secured in the commutator itself, an additional eccentric member does not need to be provided, and the number of parts are reduced, so that mass production thereof is possible. Each vehicle of the plurality of vehicles may include a vehicle processor supported by the at least one vehicle and shunt relays in circuit with the at least one vehicle processor. If the initially registered contents are not changed, and an operation log is supplied, whether or not the supplied operation log is a positive history is determined. Also, data for multiple data elements is packaged contiguously in the storage unit or across the width of the bus. The workpiece and the tool are thereby numerically controlled.
