Abstract:
The present invention relates to a reference point marking apparatus for marking a reference point of a pattern electrode in which a coating part and a non-coating part are repeatedly arranged in the longitudinal direction. The pattern electrode has portions which are expected to be a plurality of electrode lanes and which form a plurality of electrode lanes by being slit in the longitudinal direction in a subsequent process. The reference point marking apparatus includes: a moving marker for marking a reference point on the non-coated portion of each portion that is expected to be an electrode lane and is arranged in the width direction, while moving along the width direction of the pattern electrode; and a control unit for controlling the operation of the moving marker.
