Description

Mobile phone with USB interface {Mobile for having USB interface}

The present invention relates to a mobile phone equipped with a USB interface.

More specifically, the present invention relates to a mobile phone equipped with a detachable USB interface for inputting / outputting data of a memory provided in the mobile phone.

In general, a mobile phone has a voice call as a main function, and provides a short service and a wireless Internet as an additional service in addition to the voice call.

On the other hand, USB (Universal Serial Bus) is a kind of serial port, which is the same as serial port but faster and easier to connect than serial port.

The USB is a plug and play interface (PnP: Plug and Play) that connects a computer with a peripheral device such as an audio player, a joystick, a keyboard, a phone, a scanner, a printer, and the like.

The portable storage device using the USB interface and the flash memory as described above is easy to use and expands the capacity of the portable storage device, and the use of the portable storage device and the mobile phone using the USB are separated and used independently. Since there is no technology applied, development of this technology is required.

SUMMARY OF THE INVENTION The present invention has been made in view of solving the above problems, and has a first object of enabling the mobile phone to be used as a portable storage device by installing a USB interface to the mobile phone.

In addition, the USB interface has a second purpose, to be removable from the mobile phone, or to be sliding in the mobile phone from one side of the installed mobile phone to add convenience to use.

One embodiment of the present invention for realizing the above object, in a mobile phone having a memory for storing predetermined data, is installed on one side of the mobile phone, and transmits / receives data stored in the memory It provides a mobile phone equipped with a USB interface, characterized in that it comprises a USB interface for.

In particular, the USB interface, removable from the mobile phone, characterized in that the sliding movement to the groove formed in one side of the mobile phone is installed the USB interface.

These objects, features and advantages of the present invention will be more readily understood by reference to the accompanying drawings and the following detailed description. In describing the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the description thereof will be omitted.

1 and 2 are one embodiment of a mobile phone equipped with a USB interface of the present invention, Figure 3 is an embodiment of the mobile phone is applied.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The mobile phone 10 shown in FIG. 1 is a mobile phone provided with a function such as wireless internet, camera photography, etc., which is being used by users as well as supporting basic voice call function.

The mobile phone 10 includes a memory for storing an algorithm and a short message for operating the mobile phone.

For the purpose of the present invention, the memory is preferably larger than the general memory capacity.

Since the memory is a means for mobile storage, the larger the memory capacity, the less the limit on the amount of data that a user can store in the memory.

Alternatively, in addition to the memory, a memory for removable storage may be further provided in the mobile phone 10.

One side of the mobile phone 10 as described above is provided with a USB interface 20.

1 illustrates an embodiment in which the USB interface 20 is installed on the lower side of the mobile phone 10, but the USB interface 20 may be installed on the side surface in addition to the lower side of the mobile phone 10.

That is, a groove is formed in the lower side of the mobile phone 10 so that the USB interface 20 is installed, and the USB interface 20 is installed in the groove.

However, as shown in FIG. 1, when the USB interface 20 is installed at the bottom side of the mobile phone 10 and protrudes outward from the bottom side of the mobile phone 10, it may not look very good and may be inconvenient to carry.

Therefore, the USB interface 20 installed as described above is installed in the mobile phone 10 to be detachable from the mobile phone (10).

When the USB interface 20 is not used as shown in FIG. 2A, the USB interface 20 is separated from the mobile phone 10. The USB interface 20 separated from the mobile phone 10 is shown in FIG. 2B.

That is, the USB interface 20 is installed at the position of the mobile phone 10 installed so that the USB interface 20 is inserted only when the user wants to transmit / receive data through the USB interface 20.

After the USB interface 20 is installed in the mobile phone 10, the USB interface 20 is plugged into a USB port of a device having a USB port, such as a PC or a notebook, to output data stored in the memory of the mobile phone 10 as shown in FIG. .

3 illustrates an embodiment in which a mobile phone equipped with a USB interface of the present invention is plugged into a USB port of a PC 30.

As described above (PnP), when the USB interface 20 is plugged into the USB port of the PC 30, the CPU of the PC 30 recognizes this and transmits / receives data through the USB interface 20. The application is loaded and output to the monitor of the PC 30.

A user presses a corresponding letter or icon of an application output on the monitor of the PC 30 to transfer data from the memory of the PC 30 to the memory of the mobile phone 10 or from the memory of the mobile phone 10 to the memory of the PC 30. Send / receive. Power required when data is transmitted / received is not supplied via the battery of the cellular phone 10, but is supplied with USB power.

Of course, the mobile phone 10 is provided with components necessary for transmitting / receiving data in the memory through the USB interface 20 installed at one side.

In the above embodiment, the USB interface 20 is detached from the mobile phone 10, and in another embodiment. The USB interface 20 is slidably moved to a groove formed in one side of the mobile phone 10 in which the USB interface 20 is installed. The USB interface 20 can be installed.

That is, when the USB interface 20 is to be used, the USB interface 20 hidden inside the mobile phone 10 may be taken out and used.

The case where the USB interface 20 is concealed inside the mobile phone 10 is identical in appearance to that of FIG. 2A, and the USB interface 20 is inserted into the mobile phone 10 without being detached.

In this case, a protrusion may be further included to make it convenient when the user takes out the USB interface 20 hidden inside the mobile phone 10.

In addition, a cover may be further included to protect the USB interface 20 when the USB interface 20 is inside the mobile phone 10.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

As described above, the present invention has the effect that the mobile phone is equipped with a USB interface in addition to the function of the mobile phone can be used as a mobile storage device.

Accordingly, the mobile phone absorbs the demand for the portable mobile storage device, thereby increasing the mobile phone demand.
