ABSTRACT:
There is here disclosed a printed board positioning method in which various types of printed boards different in rigidity are positioned horizontally with a good operation efficiency. Relative to a printed board laid on a first guide portion and a second guide portion, a movable clamp is advanced. The printed board is clamped from opposite sides by the movable clamp and a fixed clamp. Subsequently, after a first vertically movable clamp is lowered to press one end of the printed board onto the second guide portion, the movable clamp is retreated to release the opposite side clamping condition. Thereby, the deflection of the printed board is eliminated and the printed board is placed in a horizontal attitude. Subsequently, a second vertically movable clamp is lowered to press the other end of the printed board onto the first guide portion.
