Abstract: A displacement amount calculation part in a base material processing apparatus calculates the degree of matching between an upstream data section and a downstream data section included in a first and a second detection results, which indicate time-varying changes in the positions of an edge of a base material in the width direction at an upstream and a downstream detection positions. This calculation uses calculation results obtained by sequentially calculating the degrees of matching between sub-data sections in the upstream data section and downstream sub-data sections in the downstream data section. This reduces the amount of computation and enables highly accurate detection of the amount of displacement of the base material in the transport direction on the basis of an identification result of the downstream data section that is highly matched with the upstream data section.
