It is possible to block the influence of light rays in a large range (along the depth direction of the hole). In addition, the signal of the transmission head 550 is prevented from entering the receiving head 560 after propagating through the surface of the sealing pad 520 to the avoidance hole 523 corresponding to the receiving head 560. This greatly reduces the possibility of receiving a wrong signal and improves the detection accuracy of the detection device 500.
