Abstract
A presser foot has a rod pin and is received by an engagement groove provided with a presser holder. By measuring the resistance value of the rod pin, the rod pin is identified. Terminals are provided with the engagement groove, which contact the rod pin for measuring the resistance. The terminals are connected to a circuit that connects to a circuit of a presser bar. A receiving groove is formed at the presser holder, an inserting part is formed at the lower end of the presser bar, and the presser holder is connected to the presser bar by setting the inserting part in the receiving groove and fixing it. The terminals and the circuit are provided with the inserting part connecting to the electrical resistance measuring apparatus where the resistance of the rod pin is measured, then determination apparatus identifies the rod pin and a display informs the result.
