Description

Mobile phones having a removable USB memory drive unit

The present invention relates to a portable terminal having a removable universal serial bus (USB) memory drive device that can be mounted and detached, and more particularly, convenient data communication and data storage with an external device, and charging of the portable terminal power. Portable terminal equipped with a removable USB memory device comprising a USB terminal, a memory device and a portable terminal connection terminal, a data transmission and reception cable between the USB terminal and the portable terminal, and a transmission cable having excellent expandability. It is about.

As a portable terminal, a bar type, a flip type, a folding type, and a slide type are used. Hereinafter, a folding type portable terminal which is most widely used will be described.

The main body of the conventional foldable portable terminal is a keypad composed of a plurality of buttons for inputting information on the front, a main body casing formed to surround a circuit portion formed for communication control of the portable terminal, and can be attached to or detached from the rear of the main body casing. It comprises a battery that is charged and discharged, the antenna formed on the top of the main body casing for wireless transmission and reception, and the connection terminal 13 formed on the bottom of the main body casing to exchange data by wire.

Here, the connection terminal 13 is formed to exchange data with the device 50, such as an external personal computer (PC), one end is inserted and connected to the connection terminal at the bottom of the portable terminal The other end is formed so that data can be exchanged by inserting the both ends of the separate cable formed to be connected to the connection terminal of the external device to each connection terminal. In addition, the folder unit inputs information using a keypad, or a liquid crystal display on which message reception is displayed in numbers or letters, a folder casing formed to surround the liquid crystal screen, and a call voice is converted from an electrical signal to listen to the voice. It is provided with a hydration portion formed to be. The portable terminal has been used for wireless voice communication. However, as the portable terminal has recently diversified in its functional area along with the voice communication function, a liquid crystal screen is a display device formed on the portable terminal to cope with services such as the Internet and multimedia. It is released to be configured to watch movies using the. However, if the user wants to use multimedia information such as a movie through a portable terminal, the size of the data is very large, and the service provided can only be received by using wireless communication. There is an inconvenience of having to pay a corresponding communication fee, so there is a need to use a separate storage device or to expand the storage space of the portable terminal itself.

In addition, in the case of storing data such as an address book stored in a portable terminal in an external device and vice versa, a separate connection cable has to be provided, and a large amount of data of an external device is transmitted to the portable terminal. It is impossible to save, so you have to use a separate USB drive. In particular, when charging power of a portable terminal using an external device is required, it is necessary to provide a charging device equipped with a separate USB terminal.

The present invention is designed to solve the problems of the prior art as described above, and provides convenient data communication (Upload, Download) with an external device, especially an external storage device having a large capacity, and a large capacity of data storage and the portable terminal. An object of the present invention is to provide a portable terminal equipped with a removable USB memory drive device having excellent expandability to be used for power charging.

However, in order to significantly expand the storage space of a conventional portable terminal, which is one of the main purposes of the present invention, a stand-only auxiliary memory capable of controlling data on a USB memory drive downloaded from an external device is required. Although some supplementation of the operating system of the portable terminal to be recognized as a device is required, and to use external data in a form completely mounted on the portable terminal (FIG. 2), it is necessary to add a separate connection terminal 21 physically. If the connection terminal 21 is not added, it may be mounted and used as shown in FIG. 3C. In addition, it will be relatively easy to apply to the conventional portable terminal when limited as a function of the portable USB memory drive device and the role as a power charging device.

Finally, since the detachment and installation by the detachable type are continuously repeated, sufficient durability is required. As the thickness and weight of the portable terminal are limited, the film is appropriately provided on the outside in a thin film form to have a beautiful appearance and a compact structure in addition to the functionality. .
