Disclosed are an apparatus and a method for transmitting a broadcasting service capable of signaling non-real-time 3D broadcasting content. The caliper jaws and cam profile combine to create an automatic closing action to close the release, whereby rearward pulling or squeezing movement of the trigger engages the caliper jaws to an open bow string or string loop apparatus receiving condition, and relaxing or releasing movement of the trigger closes the caliper jaws into a string retaining position. In the antenna device, since the antenna pattern is connected to a main board of the portable terminal by means of the flexible printed circuit, the stable connection of the antenna pattern and the main board can be kept.
