PURPOSE: A control method for a placard and an electronic display posting stand is provided to control a stop location of a placard on a frame by measuring wind speed. CONSTITUTION: The location of a placard is converted by moving a folding type posting stand(120). The unfolded state of the folding type placard is determined in order to stop the posting stand. The moving member of the opened folding type placard or the location of an additional apparatus connected to the folding type posting stand is sensed. The number of passages for the additional apparatus or the mobile member is sensed. The folding type placard is controlled by wind pressure and wind speed. [Reference numerals] (AA) Banner
