A chosen place on a surface of the penholder is installed with a light pervious casing, and an inner wall of the penholder, corresponding to the light pervious casing, is surrounded with at least one solar power flashing LCD (Liquid Crystal Display), such that when the LCD has absorbed sufficient solar energy, commercial prints on the LCD can be flashingly displayed.

## Background
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to a pen with a storage function, and more particularly to a pen which is provided with a USB (Universal Serial Bus) flash disk and a solar power flashing LCD (Liquid Crystal Display), such that the pen can freely store digital data and can flash to display prints at any time.
(b) Description of the Prior Art
If a computer user in old days needs to carry and transfer data to the other computer for work, the data is usually stored on a diskette or a CD (Compact Disc), and is then put into the other computer for accessing. However, as a development of the computer technology, a kind of USB (Universal Serial Bus) flash disk has shown up in the market to replace the aforementioned storage method. As the USB flash disk uses a plug-and-play USB interface, it is provided with a lot of memory space, and in the mean time, its access speed is also a lot quicker than the old floppy disk drive. Therefore, the user only needs to plug a USB connector of the USB flash disk into a USB socket of the computer to access and store the data.
However, the conventional USB flash disk is only provided with a single function of storing the data, and is also provided with a small size. Therefore, if the USB flash disk is not used, another place should be found to carefully keep it; otherwise, personal data is easy to leak out, which results in a severe outcome. On the other hand, as a book desk, an office desk, or a carry bag also contains pens and other stationery, it will be messy and is not easy to arrange if the USB flash disk is added in, which results in an unnecessary lost easily. Accordingly, how to design and develop a kind of ordinary pen which combines the USB flash disk and is added with a function of flashingly displaying commercial prints to prompt the user, decrease a chance of losing the data, facilitate the arrangement of the stationery, and increase the function of that pen, is an issue which needs to be resolved by related vendors.
SUMMARY OF THE INVENTION
The primary object of present invention is to provide a pen with a storage function, wherein a USB flash disk is combined on that pen, such that the pen can freely store digital data.
Accordingly, an end surface of a penholder of the pen of present invention is concaved with a hollow holding space for emplacing a storage device. An end of the storage device is a circuit board, and the other end is a USB (Universal Serial Bus) connector which is electrically connected with the circuit board, wherein the circuit board is located in the holding space of the penholder, and the USB connector is protruded out of the penholder for connecting with an external computer. The USB connector is sheathed with a protective outer cap which can be assembled with and separated from the penholder, to cover and hide this USB connector. While in using the storage device, the outer cap is opened, the USB connector is plugged into a USB socket of a computer for storing data, and the stored data is downloaded, so as to store the digital data in the pen. Accordingly, in carrying this pen, the data stored in that pen is also carried, thereby decreasing a chance of losing the data.
Another object of the present invention is to provide a pen with a storage function, wherein a surface of the pen is provided with a solar power flashing LCD (Liquid Crystal Display), to flashingly display commercial prints.
Accordingly, a chosen place on a surface of a penholder of the pen of present invention is provided with a light pervious casing, and an inner wall of the penholder, corresponding to the light pervious casing, is surrounded with at least one solar power flashing LCD, enabling the LCD to be installed on that inner wall. In addition, a surface of the LCD is also provided with the commercial prints, such that when the LCD has absorbed sufficient solar energy, the commercial prints can be flashingly displayed through the light pervious casing, to catch eyesight and show a location of that pen, thereby decreasing a chance of losing the pen.
