Failure to respond, or accidentally dropping on a desk while being placed on a desk, pulling the USB cable together, damaging the connected port and cable, and dropping the connected device Become.

When a mobile phone is connected to a personal computer via a USB cable or the like for a long time, the battery of the mobile phone is used more than in a normal standby state, and the mobile phone is continuously used for many hours. I couldn't use the phone.

Further, when the portable telephone is placed on the charger,
The communication port of the mobile phone was hidden by the charger, and it was not possible to exchange data with an external device such as a personal computer while charging the mobile phone.

[0009]

Therefore, in order to solve the above-mentioned problems, a battery charger according to the first aspect of the present invention is a battery charger which can charge a portable telephone and can be connected to an external device. A first coupling unit for coupling, a second coupling unit for coupling with the external device, and a transmission unit for transmitting a data signal between the first coupling unit and the second coupling unit; The means, the second coupling means, and the transmission means are constituted by a USB system.

In the battery charger according to the second aspect, the charger can charge a mobile phone and can be connected to an external device, wherein the first connecting means is connected to the mobile phone, and the second connecting means is connected to the external device. Coupling means, and transmission means for transmitting a data signal between the first coupling means and the second coupling means, wherein the second coupling means comprises a device coupling means connected for device control and a host control And a host device connecting means connected for use.

Further, the charger according to claim 3 is provided with switching means for switching to one of the second coupling means constituted by the device coupling means and the host coupling means. It is characterized by.

Further, the charger according to a fourth aspect of the present invention further comprises a power supply unit for supplying power to the charger, and supplies the power from the power supply unit to the portable unit via the first coupling unit. It is characterized in that it is supplied to a telephone.
