PURPOSE:To precisely read an inked line without any influence of dust and temperature by using a material having magnetic force to draw the inked line that indicates a position to be processed marked on a workpiece. CONSTITUTION:An inked line 17 having magnetic force marked on a wood material 16 is detected by a magnetic transducer 12 attached on an inked line sensor 9. Hereby, an inked line can be precisely detected without any trouble in the inked line detection due to powdered chips, etc., as in the case of an optical sensor. |
