PURPOSE:To make the accurate and rapid workpiece processing possible by making positioning by means of a positioning system using an adjusting control mechanism after the rough feed of the workpiece, in a device where the workpiece is processed along the mark thereon by adjusting the position of the mark on a position to be processed of the workpiece with the position of the processing machine. CONSTITUTION:A workpiece 10 such as a printed circuit board body is placed on a table 21, moved to the left with the aid of the rotation of a feed roller 34 by means of a motor 31, and the tip of the workpiece is allowed to make contact with a length measuring roll 41 of a feed amount detector 40, to prepare for processing. Then, the workpiece 10 is moved to the left by driving the motor 31 by an initiation command, but at that time output pulses from a feed amount detecting device 40 are counted in a counter when a mark 13 on the workpiece 10 is detected by means of a reference point detector 50, and the motor 31 is stopped to complete rough feed of the workpiece when said counted value coincides with the set value. Next, the mark 13 is detected by a mark detector 60, and an adjusting table of an adjusting mechanism 80 is displaced in the X and Y directions based on an output from said detector, allowing the processing machine 70 to be positioned with respect to the workpiece 10. |
