However, in the case of the above-mentioned conventional technique, the brake pad is slidably brought into contact with the side surface of the drive gear to brake the drive gear, thereby stopping the fixed position at the standby position. There is a problem in that the stop position is likely to vary due to the inertia of various movable members such as. Such a variation in the stop position of the needle causes a variation in the tension of the binding cord portion extending from the needle to the knotting portion or the binding cord portion extending from the cord storage roll to the needle, so that the binding force by the binding cord is almost constant. It becomes impossible to exert the binding effect. Especially,
When using a rubber cord as a binding cord, the amount of elastic deformation (expansion) of the rubber cord varies for each binding, and the force applied to various movable members such as the needle is likely to change. There was a risk that the needle would stop at a position that hinders the transfer of objects.
