The electronic apparatus includes a housing including a surface having a hole and a portion, a power cord having a first end passing through the hole for electrically connecting to an interior of the electronic apparatus, and a cover connected with the surface for covering the portion, thereby allowing a remaining portion of the power cord to be wound around the portion and received the power cord in the cover.

## Background
FIELD OF THE INVENTION
The present invention relates to an electronic apparatus having a function of receiving a power cord, and more particularly to an adapter, a power supply or a charger having a function of receiving a power cord.
BACKGROUND OF THE INVENTION
Adapter, power supply or charger is a popular electronic apparatus used in our daily life. The adapter, power supply or charger is generally employed to rectify and convert commercially available AC power into DC power, so as to supply the required power to operate or charge the power-receiving devices, such as printer, notebook or cellular phone.
Please refer to FIG. 1 which is a diagram illustrating a structure of a conventional adapter. As shown in FIG. 1, the conventional adapter includes a housing 11 and a power cord 13. The housing 11 has a surface 12 having a hole for passing the power cord 13 therethrough. The power cord 13 is electrically connected to an internal printed circuit board (not shown in FIG. 1) of the adapter and used as an outlet of the adapter for providing the required DC power to the power-receiving devices.
Since the power cord 13 has a length of from about 1 to 10 meters, a special consideration should be given to secure the power cord 13. A strap 14 is widely used to secure a bundled power cord 13 for storage. When the adapter is employed, the strap 14 has to be unfastened in advance and the power cord 13 can be stretched out to connect with a power-receiving device.
However, there still exist some disadvantages in practice by using the above-mentioned strap 14 to receive and secure the power cord 13 of the adapter.
1. The bundling strap 14 is readily lost, because the strap 14 is separable from the housing 11 of the adapter.
2. After the power cord 13 is bound by the strap 14, the bundled power cord 13 not only occupies a lot of space for storing but also gets entangled with other power cords or wires easily.
3. If the power cord 13 is separable from the adapter, it is easily lost when it is put away in the different place.
Therefore, there is a need to provide an electronic apparatus having a function of receiving a power cord so as to overcome the above situations encountered in the prior art.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an electronic apparatus having a function of receiving a power cord for efficiently receiving the power cord and conveniently putting the electronic apparatus away.
For the purpose of attaining the foregoing objective, the present invention is achieved by providing an electronic apparatus having a function of receiving a power cord. The electronic apparatus includes a housing including a surface having a hole and a portion, a power cord having a first end passing through the hole for electrically connecting to an interior of the electronic apparatus, and a cover connected with the surface for covering the portion, thereby allowing a remaining portion of the power cord to be wound around the portion and received the power cord in the cover.
