2. Description of the Related Art In recent years, portable devices such as smart phones, mobile phones, Portable Multimedia Players (PMPs), MP3 players, digital cameras, notebooks, and tablet PCs have been widely used to meet user's demands for mobility and portability. Generally, portable devices have a built-in battery and recharge the battery when the battery is discharged. Here, a technique for wirelessly charging a battery to maximize the convenience of charging the battery is being developed. However, since wireless charging technology transfers electromagnetic waves (or electromagnetic waves) to the air to charge the battery, the human body may be exposed to electromagnetic waves.

The wireless charging system can be broadly divided into a magnetic induction system, a magnetic resonance system, and an electromagnetic wave system. In this case, a plurality of wireless charging devices must be provided according to the wireless charging scheme applied to the portable device. For example, when wireless charging methods of portable devices used by family members are different at home, wireless charging devices corresponding to wireless charging methods of respective portable devices must be provided.

When charging the portable device wirelessly, whether or not the wireless charging device determines whether or not the portable device is located within a predetermined range is determined. Since recent types of portable devices have various types and sizes, The distance from the wireless charging device to the mobile device will vary depending on the type and size of the mobile device. On the other hand, in the conventional wireless charging device, since the charging module is fixed at a specific position to charge the portable device, the portable device may not be properly charged depending on the type and size of the portable device. Further, there is a problem in that when the portable device is not in a fixed position during wireless charging, the portable device is out of position when an external shock or shaking occurs.
