## Background
This application claims the benefit of Taiwan application Serial No. 94137182, filed Oct. 24, 2005, the subject matter of which is incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates in general to an electronic apparatus, and more particularly to a handheld electronic apparatus.
2. Description of the Related Art
Electronic apparatus can be seen everywhere nowadays. For example, people communicate to each other by mobile phones, do high-speed calculation by computers, and store various electronic files through portable storage devices.
In terms of present mobile phones, some manufacturers provide mobile phones with support function for insertion of memory cards to extend their storage capacity. However, in the process of file reading and transmission between the mobile phones and other electronic devices, the user has to prepare a transmission line beforehand, thereby leading to inconvenience in practical applications.
Besides, the user usually needs to additionally prepare a spare battery or a battery charger for use with his/her mobile phone. If the user forgets to carry the battery or the battery charger, he/she cannot use the mobile phone when the battery runs out. Therefore, the user needs to worry about carrying a spare battery or a battery charger with him/her all the time, which causes great inconvenience.
SUMMARY OF THE INVENTION
It is therefore an object of the invention to provide a handheld electronic apparatus. The spare battery can be charged as needed for the handheld electronic apparatus to perform file transmission even the user does not carry the battery charger.
The invention achieves the above-identified object by providing a handheld electronic apparatus including a main body, at least a male connector and at least a female connector. The male connector is disposed in the main body for electrically coupling to an electronic device. The female connector is disposed in the main body for electrically coupling to another electronic device. With the male connector and female connector both disposed in the handheld electronic apparatus, the user can conveniently access files and charge battery of the electronic apparatus without the need to carry any portable storage device or battery charger.
Other objects, features, and advantages of the invention will become apparent from the following detailed description of the preferred but non-limiting embodiments. The following description is made with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, a solid view of a mobile phone according to a preferred embodiment of the invention is shown. The handheld electronic apparatus is a personal digital assistant (PDA) or mobile phone for instance. The mobile phone 100 is taken as an example for the electronic apparatus of the invention in the following description. The mobile phone 100 includes a main body 101, at least a male connector 103 and at least a female connector 105. The male connector 103 and the female connector 105 are disposed adjacently at the first side 110 of the main body 101. Of course, the male connector 103 and the female connector 105 can also be disposed on different sides of the main body 101. The second side 112 of the main body 101 includes a line-receiving button 109 and a wedge bar 107. The wedge bar 107 is connected to the male connector 103. The male connector 103 and the female connector 105 can be any type of transmission interface, such as USB transmission interfaces.
FIG. 2A is a schematic diagram of the mobile phone 100 in FIG. 1 with the male connector 103 located in the main body 101. FIG. 2B is a schematic diagram of the mobile phone 100 in FIG. 1 with the male connector 103 separated from the main body 101. Referring to FIG. 2A and FIG. 2B at the same time, a transmission line 111 is disposed in the main body 101 and is wound around a winding reel 113. In this way, the transmission line 111 can be received in the main body 101 by the winding reel 113. A twist spring is disposed on the winding reel 113 for storing an elastic force. The twist spring is connected to the line-receiving button 109.
When the user is to use the male connector 103, the user takes out the male connector 103 by pushing the wedge bar 107 along direction A and takes the male connector 103 a distance away from the main body 101 by stretching the transmission line 111. Moreover, in the stretching process, an elastic restoring force is stored in the twist spring. By using the male connector 103, the mobile phone 100 can be electrically coupled to other electronic devices. For example, functions of battery charging and signal transmission can be performed on the mobile phone 100 by connecting the male connector 103 to a USB female connector of a computer. When the user uses the mobile phone 100, he/she needs not to carry a battery charger and spare batteries, and can charge the battery of the mobile phone 100 by connecting it to any electronic device with a USB female connector.
After completing usage of the male connector 103, the user only needs to press the line-receiving button 109 along direction B as shown in FIG. 2B. The twist spring is then triggered by the line-receiving button 109 to rotate the winding reel 113 and to receive the transmission line 111 by releasing the elastic restoring force. Therefore, the male connector 103 can be automatically received into the main body 101 along with the transmission line 111, which saves the time for retrieving the male connector 103.
Referring to FIG. 2C, a schematic diagram of the mobile phone 100 in FIG. 1 inserted by another electronic device is shown. The main body 101 includes a female connector 105 in addition to the male connector 103. As shown in FIG. 2C, because the portable storage device 120 generally uses a USB transmission interface, it can be inserted into the female connector 105, which is also a USB transmission interface. Therefore, the user can conveniently transmit files and various signals between the mobile phone 100 and the portable storage device 120.
The handheld electronic apparatus disclosed by the above-mentioned embodiment of the invention can be applied to the mobile phone and personal digital assistant. Through having at least a male connector and at least a female connector both disposed in one handheld electronic apparatus, the user can use the handheld electronic apparatus as a tool for file transmission via the female connector or charging the battery and storing electrical power for the electronic apparatus by connecting its male connector to other electronic devices. Therefore, the user can use the mobile phone or personal digital assistant as a handheld electronic apparatus with multiple functions of information reception, file transmission, and battery charging without the need to carry an extra battery charger, a battery charge stand or a portable storage device.
While the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
