PURPOSE:To fix a printed board without a warp and improve the accuracy in mounting of a part by pulling the printed board in width direction in the condition that one board clamp is driven in the direction of widening the interval with the other clamp board by a drive motor. CONSTITUTION:A pair of board clamping means 3 and 3 and a motor as a driving means 4 for this are arranged at the section where a part mounter is arranged. The board clamp means 3 comprises a cylinder 7, an operation lever equipped with a bulkhead member for partitioning the cylinder chamber of a cylinder 7 into two subchambers, and a holding block 10 fixed to this top. And, they are counterposed with a carry means 1 between. A step 11 a for positioning is formed at the side end of the board mounting face 11 made on the topside of the cylinder 7, and the holding block 10 is driven up and down in the directions of arrows B and C by sending in air from either of each subchambers of the cylinder 7. This way, the side margins of a printed board are caught and fixed by the holding block 10 and the board mounting faces 11 of the cylinder 7. |
