In the related art, a lighting device is arranged in the scanning pen, and the lighting device is turned on when the scanning pen is used. In this way, the illumination device is always in the on illumination state, which not only causes waste but also may cause unclear captured images due to too high brightness of the scanning medium surface 100 in the case that the brightness of the scanning medium surface 100 is sufficient.

In the embodiment of the present disclosure, the light sensing device 15 senses the luminance of the scanning medium surface 100, and the light supplementing signal is generated when the light sensing device 15 senses that the luminance of the scanning medium surface 100 is lower than a preset luminance value, so that the light supplementing device is turned on to supplement light to the scanning medium surface 100. In this way, the light supplement device is not turned on to supplement light when the luminance brightness of the scanned medium surface 100 is sufficiently large, that is, greater than or equal to the preset luminance value, and is turned on to supplement light only when the luminance brightness of the scanned medium surface 100 is lower than the preset luminance value. Therefore, the light supplementing device can be prevented from being started under the condition of no need, the power consumption of the scanning pen is reduced, the brightness of the scanning medium surface 100 can be guaranteed to be kept at proper brightness all the time, the image under the proper brightness can be collected, the definition of the collected image is guaranteed, and the user satisfaction is improved.

The photosensitive device 15 is located on a side of the plate-like body 31 facing away from the light receiving portion 32. With this structure, the light reflected by the scanning medium surface 100 can enter the light-transmitting member 30 through the light-receiving portion 32, and is transmitted in the light-transmitting member 30 to exit from the side of the plate-like body 31 facing the light-sensing device 15, and the light-sensing device 15 can sense the exiting light to detect the brightness of the scanning medium surface 100.

In addition, the position of the light-transmitting hole 101 may be set as needed. Illustratively, the light transmissive holes 101 may be proximate the head 11 of the housing 10 such that the light transmissive holes 101 are closer to the scan media face 100.

Illustratively, the transparent member 19 may be glass, and the transparent member 19 may be subjected to a double-sided antireflection treatment to improve the light transmittance of the transparent member 19. The light transmittance of the transparent member 19 is greater than 98%.

In one embodiment, the light incident surface of the light conducting element 30 may be disposed on the transparent member 19. The transparent member 19 is disposed at the scanning window 102, and the transparent member 19 is closer to the medium scanning surface 100, so that the light incident surface of the light conducting element 30 is disposed on the transparent member 19, the light conducting element 30 can better collect the brightness of the medium scanning surface 100, and the detection accuracy of the photosensitive device 15 is further improved.

In one embodiment, the light-conducting element 30 may be elongated, with the light-receiving surface of the light-conducting element 30 located at the scanning window 102 and facing the scan media face 100. The light-transmitting member 30 with such an arrangement not only can better receive the light scanned from the medium surface 100 and transmit the light to the photosensitive device 15, but also the light-transmitting member 30 with a long strip shape can be more flexibly arranged in the housing 10, thereby providing convenience for the position arrangement of the photosensitive device 15.
