According to the second aspect of the present invention, the position adjusting mechanism adjusts the installation position of the first cutting mechanism substantially along the width direction of the terminal chain, so that the separation portions to be cut are separated from each other. It is possible to handle a plurality of types of terminal chain bodies having different intervals.

According to the third aspect of the invention, the distance between the first cutting mechanism and the second cutting mechanism of the applicator along the width direction of the terminal continuum is set so that the crimp terminals are separated from each other. When an operation input for setting a value corresponding to the interval between the parts is input to the input reception means, the control means responds to the operation input and drives the motor while referring to the detection result of the position detection means. Then, the distance between the first cutting mechanism and the second cutting mechanism of the applicator along the width direction is automatically set to a value corresponding to the distance between the two separating portions of each crimp terminal. Thus, the operator does not need to purposely adjust the distance between the first cutting mechanism and the second cutting mechanism of the applicator along the width direction, and the working efficiency is good.
