板の切断溝加工装置。 A pair of eccentric rollers that sandwich a printed circuit board from both sides are each fixed to a rotating shaft, and the eccentric rollers are made to face each other so that the rotation center positions of the pair of eccentric rollers are line symmetrical, and the rotating shaft is The printing apparatus is connected by a rotation transmission means that rotates the eccentric rollers by the same amount of rotation in opposite directions, and the rotation shaft is provided with means for applying a rotational force that rotates the outer circumferences of the eccentric rollers in a direction in which the outer circumferences of the eccentric rollers approach each other. 1. A cutting groove machining device for a printed circuit board, characterized in that the circuit board is held between the substrates and the center position of a cutting cutter is provided from the upper and lower surfaces of the printed circuit board so that the center position thereof coincides with the center position of the eccentric roller.
