Disclosed is a laser wireless lantern slide page turner with USB charge and automatic page turning, which belongs to the computer technique field, and consists of a transmitting part and a receiving part, wherein, the transmitting part is composed of a command coding module, a laser transmitting module, a charging module and a transmitting module, the command coding module transmits codes to the transmitting module, and the laser transmitting module receives a transmitting laser command of the command coding module to make a laser module group transmit laser; the transmitting module implements the radio-frequency transmission to the codes sent from the command coding module; the charging module is connected on a jack of a USB module of the receiving part, and the receiving part is composed of a receipt decoding module, a main control module and the USB module, and the receipt decoding module receives signal information of the transmitting module in the transmitting part; the main control module parses a coded command sent from the receipt decoding module and drives the USB module to execute the command; and the USB module is connected with a computer. The invention has the advantages that the page turner can be charged at USB ports of the computer, so the lantern slide can realize the automatic page turning at regular time.
Description
technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a laser wireless slide page turner which is used in slide teaching and can automatically turn pages through USB charging. Background technique [0002] At present, there are many page-turning laser pointers on the market, which are composed of a transmitter and a receiver. However, the disadvantage of these laser pointers is that the transmitter is powered by a button battery or a dry battery. Since a large current is used to generate laser light, the use time is short, which brings great trouble to the user, and the battery needs to be replaced frequently. In addition, the page-turning laser pointers on the market only have the page-turning function forward and backward and do not have the automatic page-turning function of the slideshow according to the adjustable set time. Contents of the invention [0003] In order to overcome the short service time of the ex...
