The light exiting portion 623 is emitted onto the color sensor 41; the color sensor 41 receives the diffusely reflected light and outputs a color signal to the controller 43, and the controller 43 passes the wireless transmission module 45 The color signal is transmitted to a peripheral device such as a mobile phone or an ipad, and the processor of the peripheral device receives the color signal and adds the color, which is convenient and flexible.

Please refer to FIG. 13. FIG. 13 is a schematic structural diagram of a color picking pen in a fourth embodiment of the present application. The structure of the fourth embodiment of the color pick-up pen of the present invention is similar to that of the second embodiment, except that the light-emitting portion 623 of the first light-guiding member 62c in the fourth embodiment has a receiving port 6237, a color sensor. 41 is soldered to the control circuit board 40 and received in the receiving port 6237 to increase the light capturing rate of the first light guiding member 62c; the light incident portion 641 of the second light guiding member 62c defines a receiving port 6417. The light source 42 is soldered to the control circuit board 40 and received in the receiving port 6417 to increase the light capturing rate of the second light guiding member 62c. In the present embodiment, the receiving

openings

6237 and 6417 are recessed from the light emitting surface of the light exiting portion 623 and the light incident surface of the light incident portion 641, respectively.

Please refer to FIG. 14. FIG. 14 is a schematic structural diagram of a color picking pen in a fifth embodiment of the present application. The structure of the fifth embodiment of the color picking pen of the present invention is similar to that of the second embodiment, except that the light incident surface 6212 of the light incident portion 621 of the first light guiding member 62d in the fifth embodiment is inclined. The surface of the light-incident surface 6212 is increased to allow more diffuse light to enter the first light guide 62d; the light-emitting surface 6432 of the light-emitting portion 643 of the second light guide 64d is inclined. The surface increases the area of the light-emitting surface 6432, so that more light can be emitted from the light-emitting surface 6432. The inclined surface of the light incident surface 6212 extends rearward from the top surface of the pen head 22 and obliquely outward. In use, the diffuse reflection light passing through the object surface 300 passes through the refracted surface of the light incident surface 6212 and enters. The first light guide 62d increases the amount of light entering the first light guide 62d. The inclined surface of the light-emitting surface 6432 extends rearward from the top surface of the pen head 22 and obliquely outwardly. The light generated by the light source 42 is outwardly expanded by the refracting of the inclined surface of the light-emitting surface 6432, thereby increasing The area of the surface 300 of the object is illuminated to reflect more light onto the light incident surface 6212.

The above is a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It is the scope of protection of the present invention.
