The transition portion 4422 and the light-gathering portion 4424 of the present embodiment are smoothly transitioned through a curved surface or an arc surface.
Further, it is preferable that the light supplementing and transmitting member 44 of the present embodiment is an integrally formed white translucent plastic member. The light supplementing transparent member 44 may be integrally formed by injection molding.
Further, the light-transmitting body 442 of the present embodiment is an irregular curved surface or arc surface with equal wall thickness having a curved or arc-shaped arch or protrusion structure.
In order to save space and material and reduce waste, the light supplementing transparent member 44 of the present embodiment is provided as an elongated strip member. The length of the light-supplementing transparent member 44 is set to be adapted to the size of the scanning window 222 so as to supplement light without dead angles.
To better optically refract and diffusely reflect light to better supplement the light at the scanning window 222, the surface of the light-supplementing light-transmitting member 44 or the light-transmitting body portion 442 is blurred or embossed.
