Abstract:
A method of causing a wound-on belt to contact a printed wiring board and conveying the printed wiring board by utilizing a frictional force produced between the wound-on belt and the printed wiring board, the method comprising the steps of:providing two conveying units each of which includes a wound-on belt and two rotatable wheels on which the wound-on belt is wound to have a straightly extending portion which straightly extends between the two rotatable wheels, such that the two conveying units are spaced from each other in a direction parallel to a printed wiring board, and such that the respective straightly extending portions of the two wound-on belts of the two conveying units cooperate with each other to engage opposite side surfaces of the printed wiring board, respectively, and sandwich the printed wiring board in a direction substantially parallel to the printed wiring board, and conveying the printed wiring board by rotating the rotatable wheels of the two conveying units, and thereby moving the two wound-on belts, while utilizing a frictional force produced between each of the two wound-on belts and the printed wiring board.
