Problems solved by technology

[0003] However, the existing laser page presenters still have the following technical problems: when turning pages back and forth, two buttons are required, especially when continuous page turning is required, the buttons need to be pressed multiple times, and the user is prone to fatigue after long-term use , and the tactility of the buttons will deteriorate with the increase of the use time, and the user experience is not good

Embodiment 1

[0030] Such as Figure 1-3 Shown, a kind of laser page presenter, it comprises a pen case 1 and a main control module that is arranged in the pen case 1, the core component of main control module can be single-chip microcomputer or DSP, and main control module adopts prior art. , not shown in the figure, it also includes a rolling button module 2 that is rotatably installed on the pen case 1, and the rolling button module 2 includes a roller 3, a grating 4, a connecting rod 5, two light emitters 6 and two light receivers 7, the two light transmitters 6 and two light receivers 7 are electrically connected to the main control module, the grating 4 is coaxially fixed in the drum 3, and the connecting rod 5 passes through Pass the roller 3 and fix both ends with the pen case 1, the two light emitters 6 and the two light receivers 7 are fixed on the connecting rod 5 and are respectively located on both sides of the grating 4, the two light emitters The position of 6 corresponds to...

Embodiment 2

[0033] A page-turning detection method of a laser page-turner, the method is based on the laser page-turner in embodiment 1, and it comprises the following steps:

[0034] (1) Obtain initial signals of two optical receivers 7 by the main control module;

[0035] (2) Whether the signals of the two optical receivers 7 are detected by the main control module in real time, if so, it is judged that there is a page-turning action and enters the next step, if not, it is judged that there is no page-turning action, and then returns to step 2 to continue detection ;

[0036] (3) According to the initial signals of the two optical receivers 7 and the sequence in which the two optical receivers 7 receive the signals from the optical transmitter 6, the main control module judges whether to turn pages forward or backward.

[0037] As preferably, in said step (3), it is also judged by the main control module whether the signals received by the two light receivers 7 are periodically repeate...

Abstract

A laser page turning pen comprises a pen shell and a main control module and further comprises a rolling key module rotationally installed on the pen shell, 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 all electrically connected with the main control module, the grating is coaxially fixed in the roller, and the connecting rod is connected with 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, the positions of the two light emitters correspond to the positions of the two light receivers, and it is always guaranteed that the two light receivers asynchronously receive signals of the light emitters in the process that the grating rotates along with the roller. And when the rotation directions of the grating are different, the front and back sequences of signals received by the two light receivers from the light emitter are different. The laser page turning pen is more convenient in page turning and better in user experience. The invention further provides a page turning detection method of the laser page turning pen.

Description

technical field [0001] The invention relates to the technical field of page-turning pens, in particular to a laser page-turning pen and a page-turning detection method thereof. Background technique [0002] Laser page presenters, also known as electronic pointers, are usually used in public places such as teaching and conferences, and are used with large screens, projectors, computers, etc. In addition to the mapping function of the traditional laser pointer, it can also directly and remotely control the computer or multimedia projection equipment by pressing the forward and backward page turning buttons on the laser presenter, so as to realize free page turning and Feel free to demonstrate, more convenient to use. [0003] However, the existing laser page presenters still have the following technical problems: when turning pages back and forth, two buttons are required, especially when continuous page turning is required, the buttons need to be pressed multiple times, and ...
