PURPOSE: A board contact system is provided to safely fix and remove a board when combining or separating a variety of boards from a board supporting stand. CONSTITUTION: A board(14) is fixed or removed from a supporting stand(10) as a bearing having a contact rail on the end of a contact end(16) on both ends of the board is slid in or out. The installing power generated by air pistons(24,26) moves the supporting stand in the installing direction to combine the board with the supporting stand. Also, the fixing/removing force moves the stand in the fixing/removing direction to induce the fix and removal between the board and the supporting stand. Therefore, the damage caused by workers and materials is prevented when fixing or removing the board from the supporting stand.
