1 is a schematic diagram showing a laser pointing device capable of inputting / outputting data according to the present invention, wherein the laser pointer 100 constituting the transmitting unit includes a laser pointing unit 101 and a radio frequency (RF) transmitting unit 103. In addition, the laser pointing portion 101 is formed with a laser hole 105 for guiding the laser beam emitted from the laser oscillation portion by the laser pointing button 107, and page-up of the content displayed by the application for presentation. Buttons 109 and 115 for performing the down function are provided.

The wireless transmitter 103 performs a wireless transmission function by converting and modulating a mouse signal input from the buttons 109 and 115. As shown in FIG. 2, a signal is input from the buttons 109 and 115. As shown in FIG. The receiving encoder 201 and the wireless transmission module 203 are installed.

In addition, the adapter 120 has an interface that can be connected to the USB port 121 of the computer to execute page up / down or data input / output according to a wireless signal received from the laser pointer 100.

As shown in FIG. 3, the wireless reception module 205 receives and demodulates the page up / down signal and the data input / output signal transmitted from the laser pointer 100 to the microcontroller 207, and the wireless signal. A microcontroller 207 determines whether a demodulated signal is input from the receiving module 205, decodes the input demodulated signal, and transmits the decoded demodulated signal to a computer through the USB port 121, and a memory module that stores / outputs high capacity data. It consists of 206.

Laser pointing system according to the present invention is provided with a wireless transmission and reception module (203, 205) it is possible to perform an accurate operation regardless of the obstacle at a certain distance.

In this case, the laser pointer 100 converts the signals of the buttons 109 and 115 provided in the wireless transmitter 103 into serial data by the encoder 201 and transmits the serial data to the wireless transmitter module 203. Is modulated into a radio signal in the radio transmission module 203 to be transmitted to the radio reception module 205 of the adapter, and the adapter 120 receives the radio signal transmitted from the laser pointer 100 to receive the radio reception module 205. The serial data generated by demodulating the data is transmitted to the microcontroller 207, and the microcontroller 207 decodes the serial data input from the wireless reception module 205 and sends the serial data to the central processing unit of the computer.

In addition, the button information input from the radio transmitter 103 is converted into serial data by the encoder 201 and transmitted to the radio transmitter module 203, which is modulated into a radio signal by the radio transmitter module 203. And is received via the receive wireless module 205 of the adapter 120.

The received wireless signal is demodulated into serial data and transmitted to the microcontroller 207. The microcontroller 207 decodes the received serial data and transmits the received serial data to the central processing unit of the computer.

In particular, when the computer and the laser pointer 100 are connected to the USB port 121, the computer reads the data (high-capacity file to be used for the presentation) stored in the memory module, and the program for presentation on the computer. You will be able to run your presentation on.

In other words, if only the laser pointer 100, which is an essential equipment for presentation, possesses a separate mobile storage device or a device such as a laptop to store and move data.

Of course, when carrying the laser pointer 100, the presentation file is connected to the working computer through a USB port to copy and save the file.

The encoder 201 of the wireless transmitter 103 inserts a unique ID of the laser pointer 100 having a predetermined number of bits in the process of encoding data input from the buttons 109 and 115.

The microcontroller 207 of the adapter 120 checks whether the wirelessly received data is a unique ID registered in the corresponding adapter 120 and transmits the data to the computer when the unique ID is registered.

Here, the adapter 120 registers the unique ID by storing the unique ID of the laser pointer 100 that is input for the first time after the power is applied.

That is, the adapter 120 is connected to the USB port 121 of the computer and the arbitrary mouse button provided in the laser pointing unit 101 is enabled for a predetermined time to convert the unique ID of the laser pointer 100 into the adapter 120. In this case, the adapter 120 processes data including the first unique ID registered until the adapter 120 is reset.

Therefore, the user can use the laser pointer 100 according to the present invention as one set for any adapter 120, and the wireless transmitting / receiving modules 203 and 205 of the laser pointing system according to the present invention are wireless communication. In addition to the projector connection computer used by the presenter, the presenter is present within a predetermined radius for wireless communication with only one laser pointer 100 even in an environment in which the presenter is presenting to the audience through a plurality of laptop computers such as a notebook that the audience possesses. The same data can be transmitted and presented to a plurality of computers connected to the 120.

Of course, even if the memory module and USB port are added to a general portable laser pointer without the above page up / down function (only the laser oscillation is required without the transmitter and receiver), the file for presentation can be easily moved. It becomes possible.

As described above, the present invention installs a memory module capable of storing a high-capacity document file and a function of a wireless mouse in the laser pointer used in the presentation, so that the page up / down function can be executed by the laser pointer itself. It can solve the trouble of going up and down the page by going to the computer, and do not need to carry a separate notebook computer, USB drive, etc. to move the high-capacity document file (data).

In other words, if only one laser pointer is taken, up / down of the screen and loading of the presentation file are made simple, thereby making presentation work easier.
