Abstract: PURPOSE: A metal body detection method is provided to prevent mis-detection of the metal body mixed in powder and to improve detecting performance. CONSTITUTION: Signals input from a detecting coil for metal body detection are detected at a specific interval for specific hours by a CPU(central processing unit). An algorithm for generating a detecting signal simply when the signal over a predetermined level is input is set up. Herein, the electronic noise transmitted via a coil is removed, and the mis-operation during detection is avoided. Thereby, the metal body detection method is easily applied to a place of defective surrounding or where high frequency is generated. According to the prevention of mis-operation due to the position and the shape of the metal body in the powder, stable working is possible.
