BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable USB device, and more particularly, to a USB device having an advertisement and an additional function having a display driven by a solar cell while selectively exposing a connector only in use.

Recently, various types of portable storage media have been developed in response to the rapidly changing network environment and the need for more convenient data storage and mobility. Among these new storage media, a high-capacity storage device using flash memory is a memory type. The demand for portable storage devices is growing rapidly. The portable storage device of such a memory type is becoming larger due to the price drop due to the development of memory production technology. In recent years, the portable storage device of the memory type has been provided to consumers for accessories or bundles of products such as PCs and personal digital assistants (PDAs, PMPs, UMPCs).

In other words, the portable storage device of the memory type has been replaced by the existing floppy disk and 16GB large-capacity has been spread to tens of thousands of won not only increases the purchase of the general public, but also does not require a separate adapter simply connected to the computer Not only can it be connected to a PC or personal information terminal using a USB port, but also it can be manufactured compactly without requiring a separate power supply.

On the other hand, a memory-type portable storage device having the above advantages is based on USB interface technology, which is initially provided by Compaq, IBM, Intel, and Microsoft to provide a simple way to integrate computers and phones. It is a peripheral bus protocol developed by several companies. This protocol has evolved and has been extended to the concept of easily integrating up to 127 peripheral devices in a PC, and has been released in the USB 1.0 specification. These USB technologies provide full support for real-time data on voice and compressed video. Advances in mixed mode synchronization, development of new devices to increase PC performance and various PC configurations.

Currently, many products with the above USB interface are released, and most peripheral devices connected to a PC, such as a printer, a scanner, a keyboard, a mouse, a joystick, a gamepad, a video camera, a still image camera, Modems, ISDN adapters, and Ethernet adapters can all be connected. In addition, a connector that can be used by connecting an existing device to a USB device, for example, USB to IDE, USB to PS / 2, USB to Printer Port, USB to Serial Port Can be used like a device.

Looking at the portable storage device of the memory type according to the prior art, the USB connector is provided on one side as an input and output means of the memory, wherein the USB connector is covered by a separate protective cap by being exposed to the outside.

That is, the conventional memory type portable storage device has a protective cap that is fitted to the memory stick body to surround the USB connector, and when used, there is not only inconvenience to separate the protective cap from the memory stick body.
