A system for placing an implant in the body includes an elongated member having at least one inner lumen extending from a proximal end portion of the member to an opening in a distal end portion of the member. A reception side apparatus receives the SDI data transmitted via the coaxial cable by a reception interface device, extracts data to be transmitted from a video storage area of received SDI data and determines whether the data to be transmitted is the video stream data or the MPEG data by an SDI data extraction processing device to output it. The electrode terminal includes an inner terminal plate formed at an inner side of the cap plate and a main coupling protrusion and a first auxiliary coupling protrusion protruding from the inner terminal plate and respectively coupled to a first fastening hole and a second fastening hole of the lead tab. The rollers are arranged to rotate about axes in the conveyor direction to provide a low-friction rolling surface to articles being pushed sidewise on the belt.
