11 is a perspective view illustrating a sliding type USB memory device according to the present invention, and FIG. 12 is a perspective view illustrating a sliding state of the cover 200 of FIG. 11. The present invention is described with reference to FIGS. 4 to 12. The operation and effects of the sliding type USB memory device will be described.

First, in order to use the sliding type USB memory device according to the present invention, sliding the cover 200 forward from the main body 100, the guide rail of the cover 200 along the guide groove 110 of the main body 100 As the 210 is slid, the front side portion of the cover 200 is exposed to the outside.

At this time, the guide rail 210 of the cover 200 is stopped by the stepped portion 120 formed at the tip of the guide groove 110 of the main body 100, and the cover 200 is connected to a terminal (not shown) accommodated therein. Only the part is exposed to the outside and connected to an external device such as a computer.

On the other hand, the user can easily push the cover 200 by placing a finger on the plurality of protrusions 220 formed on the outer upper surface of the cover 200.

In addition, the outer surface of the main body 100 is smoothly formed in a round shape, so that when the user attaches the USB memory device, the user can feel a sense of stability and can feel the beauty in terms of design.

When the user finishes using the USB memory device, the cover 200 is slid back to the rear side to prevent the inflow of dust into the USB memory device.

Then, the front surface of the cover 200 is in a state in which the open front surface of the main body 100 is closed, and since the main body 100 and the cover 200 have the same thickness, the six sides form a closed rectangular parallelepiped shape.

In this way, the main body 100 and the cover 200 are joined in a closed rectangular parallelepiped shape so that there is no space open to the outside, so that foreign substances such as dust during storage are connected to the terminal and the printed circuit. Since it does not flow into the board, problems such as poor connection of the connection terminal, malfunction of the printed circuit board, or poor sliding operation can be solved.

In addition, the main body 100 and the lid 200 are each formed integrally, and the lid 200 is slidable from the main body 100 due to the structure itself of the main body 100 and the lid 200, Since the cover 200 does not require a separate structure for sliding from the main body 100, it is possible to reduce the manufacturing cost of the USB memory device and improve the productivity of the product.

In addition, since the guide rail 210 is formed so that the bottom is opened integrally with the open bottom of the lid 200, as described above, to increase the storage space of the lid 200 to increase the memory capacity. In this case, the width of the guide rail 210 itself may be increased, and the inner accommodation space of the guide groove 110 of the main body 100 accommodating the guide rail 210 may be increased.

Therefore, although the size of the actual USB main body is increased, the size of the cover 200 which is exposed to the outside sliding is felt as the same as before. That is, the lid 200 has a larger width than the front portion in which the rear side portion in which the printed circuit board is accommodated is actually larger than the front side portion in which the connection terminal is accommodated.

Due to this structure, a more compact design of the USB memory device can be realized.
