description A laser page turning pen comprises a pen shell and a main control module arranged in the pen shell, and is characterized by further comprising a rolling key module rotationally mounted on the pen shell, and the rolling key module comprises a roller, a grating, a connecting rod, two light emitters and two light receivers. The two light emitters and the two light receivers are electrically connected with the main control module, the grating is coaxially fixed in the roller, the connecting rod penetrates through the roller, the two ends of the connecting rod are fixed to the pen shell, the two light emitters and the two light receivers are fixed to the connecting rod and located on the two sides of the grating respectively, and the positions of the two light emitters correspond to the positions of the two light receivers. When the grating rotates along with the roller, it is always guaranteed that the two light receivers asynchronously receive signals of the light emitter, and when the rotation directions of the
