Therefore, when the control system (not shown in the figure) of the device simultaneously energizes the two photoelectric sensors 2, the control system can detect whether the two light paths 21 are unblocked by receiving the signals returned by the photoelectric sensors 2, thereby achieving the purpose of accurately detecting the small ball 100 passing through the target ring 1. Because the directions of the two light paths 21 are opposite and do not interfere with each other, and the two photoelectric sensors 2 are both arranged in the circular ring 1, and only the light hole 12 is communicated with the outside, the infrared interference of most of the outside is prevented, and the strong anti-interference capability is achieved.
