However, since the conventional electronic blackboard device has only the function of printing the image drawn on the board on the paper, the paper consumption is extremely large and the paper is reused as digital data. Had a problem that it was necessary to prepare a special device.

Therefore, the present invention provides an electronic blackboard device which can reduce paper consumption and can transfer digital image data to other devices such as a portable terminal and a personal computer as digital data as they are for reuse. The purpose is to

[0007]

To this end, the present invention provides a main control unit for controlling the entire electronic blackboard device, and an image moving unit for changing the position of the image of the board with respect to the scanner controlled by the main control unit. An electronic blackboard device is composed of a scanner that is controlled by the main control unit and converts an image into a digital image signal, and a transmission control unit that is controlled by the main control unit and that controls the data conversion unit and the infrared transmitter. Controlled by the control unit, it has the function of outputting digital image data output from the scanner, and the infrared transmitter has the function of outputting the data output from the data conversion unit to the outside by modulating the infrared emission. It is a thing.

[0008]

According to the present invention, with the above-described configuration, the image drawn on the board can be captured as digital data in a portable terminal or a personal computer without being output on paper. Further, since the infrared interface is used, there is no need to connect with a cable or the like, and data can be transferred very easily.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an electronic blackboard device according to an embodiment of the present invention. In FIG. 1, 11 is a main control unit for controlling the entire electronic blackboard, 12 is a switch electrically connected to the main control unit 11, 13 is a board 1 connected to the main control unit 11.
An image moving unit that mechanically moves 4; 14 is a board on which an image is drawn by a pen; 15 is a scanner that is connected to the main control unit 11 and is installed so as to optically read the image drawn on the board 14; A printer 16 is connected to the main controller 11 and to the scanner 15. Reference numeral 17 is a transmission control unit connected to the main control unit 11 and connected to the data conversion unit 18 and the infrared transmitter 19. The data converter 18 is connected to the signal line output from the scanner 15,
Further, it is connected to the infrared transmitter 19. Infrared transmitter 19
Is installed at a position where infrared communication with the outside such as the front surface of the electronic blackboard device can be performed.

FIG. 2 is a flowchart of the operation of the electronic blackboard device of one embodiment of the present invention, and the operation will be described next. In step 11, the switch 12 gives an instruction to print an image or output by infrared rays. In step 12, the main control unit 11 outputs a signal to the image moving unit 13 to move the image, and at the same time, outputs a signal for instructing the scanner 15 to optically read the image on the board 14 and convert it into a digital signal. Output. When the instruction in step 11 is printing by the printer 16 in step 13, the process proceeds to step 14 and the image read by the scanner 15 is printed by the printer as in the conventional electronic blackboard apparatus. If the infrared output is instructed in step 13, the process proceeds to step 15, and the transmission control unit 17 is instructed to output the data, and the process ends.

Here, the operation of the transmission control section 17 will be further described. FIG. 3 is a flowchart of the operation of the transmission control unit of the electronic blackboard device of one embodiment of the present invention. Step 21
At, the main control unit 11 instructs the transmission control unit 17 to output infrared rays. In step 22, the transmission control unit 17 instructs the data conversion unit 18 to convert the data. The data conversion unit 18 divides the digital data output from the scanner 15 into 8-bit units, and divides them into infrared transmitters 19.
Output the data to. In step 23, the transmission control unit 17
Outputs an infrared transmission instruction to the infrared transmitter 19,
The 8-bit data output from the data conversion unit 18 is modulated into infrared rays and output to the outside.

[0013]

As described above, according to the present invention, by outputting the digital image data output from the scanner inside the electronic blackboard device to the outside, the number of paper documents can be prevented from increasing unnecessarily. It can be reused as it can be transferred as digital data to mobile terminals and personal computers. Further, since data transfer is performed using an infrared communication device, there is no need to connect with a cable or the like, and data can be easily transferred to other devices.
