The memory means 11 memorizes an unloaded dolly weight of each of dollies 5 and each unit component-weight of components 4 to be loaded on the dolly 5. The weight information acquisition means 12 acquires caster's weight information transmitted from each of weight-sensor mounting casters 7 of the dolly 5. The weight calculation means 13 calculates a loaded dolly weight by summing up the acquired caster's weight information. The counting means 14 calculates a component-loaded weight by subtracting the unloaded dolly weight stored in the memory means 11 from the calculated loaded dolly weight, and also calculates the number of components loaded on the dolly 5 by dividing the component-loaded weight by the unit component weight stored in the memory means 11.SELECTED DRAWING: Figure 1
