The electrical treatment device according to this design consists of a main unit and a cord connecting it to an electrical signal output unit, with the cord omitted in the diagram. The cord is connected to the black part that appears on the far right in the front view (the small circular black part that appears at the bottom of the right side view). In the front view, the five bullet-shaped tips extending upward from the top of the main unit are the connection terminals. When in use, the curved contact surfaces of the contact terminals are brought into contact with the area of ​​the person receiving treatment (for example, the face). Of the five connection terminals shown in the front view, the terminals located at both the left and right ends are not movable (non-movable connection terminals). In the front view, the three connection terminals located in the middle are each independently movable (movable connection terminals), and are constantly subjected to an upward biasing force from the main unit by a spring built into the main unit. When subjected to a force toward the main unit, they retract into the main unit against the biasing force of the spring. When subjected to a force directed toward the main body and fully immersed within it, the height of the tip contact surfaces of the three central contact terminals (possible connection terminals) is the same as the height of the tip contact surfaces of the contact terminals (non-movable connection terminals) at both ends of the main body (see reference diagram showing the state of use). On the other hand, when not subjected to a force directed toward the main body, the height of the tip contact surfaces of the three movable contact terminals is formed to be higher than the height of the tip contact surfaces of the contact terminals (non-movable connection terminals) at both ends of the main body, as shown in the front view, rear view, left side view, and right side view. When performing treatment using an electric treatment device according to this design, the electric treatment device is held by gripping it from the bottom side, and the curved tip contact surfaces of the contact terminals are brought into contact with the area of ​​the person receiving treatment. For example, when treating the face, the electric treatment device is held by gripping it from the bottom side, and the tip contact surfaces of the non-movable contact terminals are brought into contact with the face line area of ​​the person receiving treatment, so that the five contact terminals intersect with the face line area extending from below the chin towards the top of the head. From this position, with the tip of the central movable contact terminal still in contact with the face, the electrical treatment device is tilted so that the tip of the non-movable contact terminals on both the left and right sides of the main unit are in contact with the face, and then the treatment is performed. Next, with the tip of the central movable contact terminal still in contact with the face, the contact between the tip of the non-movable contact terminal on the main unit and the face is released, and the electrical treatment device is tilted so that the tip of the non-movable contact terminal on the upper side of the other side of the main unit is in contact with the face, and the treatment is performed.This procedure is performed by sequentially repeating the movements along the jawline, which extends from below the chin towards the top of the head. The same movements can be used to perform the treatment on other parts of the body of the person receiving the treatment using the electrical treatment device related to this design.
