A board positioning method includes the steps of selecting one of a plurality of positioning sections or stations for positioning a particular type of board located in a specified position. The method allows positioning different types of boards in specified positional relationships by locating only a positioning section corresponding to the board to be positioned, so that the positioning section faces the board located in the specified position. The positioning section is moved into the specified location by means of a support member. Thereby, positioning various types of the boards in a specified common position is possible without the need to make adjustments to a single positioning station.
