In an embodiment of the present invention, the brush fingerprint reading device may further comprise a protective cover that may be used to protect the soft or rigid contact surface of the groove that exposes the cover. 8A and 8B are diagrams schematically showing the use of the protective cover 27 in accordance with an embodiment of the present invention; and FIG. 9 is a schematic view showing the present invention. A schematic view of the use of the protective cover 27' of another embodiment. In Figures 8A, 8B, and 9, the protective cover is movably coupled to the cover to protect the soft or rigid contact surface from which the groove is exposed.

For example, in the embodiment of Figures 8A and 8B, the protective cover 27 is coupled to the cover 11' by a pivot 29 for rotation relative to the cover 11', for example, in the direction of the arrow shown in Figure 8B. Make a turn. In the embodiment of Fig. 9, the protective cover 27' is coupled to the cover 11" by the rail 31 to slide relative to the cover 11", for example, in the direction of the arrow shown in FIG.

Since the brush type fingerprint reading device often has a short fingerprint brushing slide because of its small volume, when the user uses the brush type fingerprint reading device, the force may be uneven or the finger size thereof may be different. The large size causes the brush-finished fingerprint reading device to fail to read its fingerprint correctly. In one embodiment of the present invention, as shown in Figures 8B and 9, the protective cover (27, 27') can extend the length of the fingerprint swipe slide 33" when opened to increase the reliability of fingerprint reading.

Although the present invention has been described with reference to the preferred embodiments and drawings, those skilled in the art can understand that various modifications, changes and equivalent alternatives can be made without departing from the spirit and scope of the present invention. These modifications, variations, and equivalent alternative designs are still within the scope of this patent application.
