Abstract

PROBLEM TO BE SOLVED: To attain automatic edit/output by adopting a double structure of a piezoelectric element device and an LED display device for a board face and using a pressure caused when a character or a graphic is drawn so as to obtain position information and to input, edit and store the information. SOLUTION: A double structure of a piezoelectric element device 9 and an LED display device 102a is adopted for a board face and an information input/display means 1 allows a piezoelectric element reader 11 to collect a pressure exerted by a writing rod 8 in the case of drawing a character or a graphic. A CPU 12 analyzes the collected information to calculate position information and allows an LED driver 13 to instruct writing of an LED in response to color information designated by the user. The position information resulting from the pressure and the color information which are collected by the CPU 12 are stored in a hard memory 14 or an FD 18 in an FD driver 17, and the information is received, edited and stored so as to conduct automatic edit/output.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic blackboard for storing, editing and outputting image data of characters and figures written on a blackboard.

[0002]

2. Description of the Related Art Currently, a blackboard is used to write characters on a board surface using chalk. However, the problem with using chalk is that when writing or erasing characters, a large amount of powder comes out and it takes time to clean, and since there is no printing means, the contents written on the blackboard can be deleted. It had to be copied to a notebook or the like. Therefore, instead of using chalk, those that use a pen have come to be used. Some products have functions such as printing.

[0003]

Among the above-mentioned products, the problem with using a pen is that the pen runs out of ink during writing and the characters are blurred because a consumable pen is used. I have done it. In the case of a blackboard having a printing function, there is a problem that thin characters or fine characters are not printed during printing. Also, the content written on the blackboard,
They could only save on printed paper or save a copy. Furthermore, since the range of writing characters is limited, it is impossible to display and save a large amount of data.

An object of the present invention is to provide an electronic blackboard capable of holding a large amount of information written on a blackboard as image data and automatically editing and outputting the information.

[0005]

In order to achieve the above object, an electronic blackboard according to the present invention has a plate surface having a double structure of a piezoelectric element device and an LED display device, and reduces the pressure generated when writing characters and figures. Information input / display means having a CPU for instructing which LED should be turned on based on the position information and the color information specified by the user while obtaining the position information using the information, and information for holding a large amount of such display information in a memory Automatically edits such information if necessary, and saves mail, fax, etc.
Automatic information editing / output means capable of performing transmission according to.

[0006]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram of the present invention, FIG. 2 is a configuration diagram of the present invention, FIG. 3 is a configuration image of a plate surface of the present invention, FIG. 6 is an automatic editing image of the present invention, and FIG. 6 is a flowchart showing a flow of operation of the present invention.

The present invention, as shown in the block diagram of FIG.
Information input / display means 1 for electronically displaying characters and figures, information storage means 2 for holding a large amount of such information, and automatic editing, printing, and mailing of such information as necessary And an information editing / output unit 3 capable of performing transmission by FAX or FAX. The information input / display means 1 comprises a position information acquisition means 4 and an information display means 5, and the information storage means 2 comprises a hard disk and an F
D, the automatic information editing / outputting means includes a list creating means 6, an image enlarging / reducing means 7, a facsimile, a mail, and printing.

FIG. 2 shows a configuration diagram of the present invention. The plate surface of the present invention is composed of the piezoelectric element device 9 and the LED display device 1.
02, the information input / display means 1 collects the pressure applied by the writing rod 8 when writing characters or figures by the piezoelectric element reader 11, and the CPU 12
, And the LED driver 13 turns on the LED according to the result and the color information specified by the user. The pressure position information and the color information collected by the CPU 12 are stored in the FD in the hard memory 14 or the FD driver 17 at regular time intervals or according to a user's request.
18 is stored. The stored data is printed 16 by the print driver 15 or output to the outside as a FAX 21 or a mail 21 using a built-in modem 19 in response to a user request.

FIG. 3 shows a configuration image of the plate surface of the present invention. The plate surface of the present invention includes a mesh-shaped piezoelectric element device 22 and an LED display device 23. The piezoelectric device 22 is provided on the surface, and the LED display 23 is superposed thereafter.

FIG. 4 is an image of a plate surface according to the present invention. The color of the character or the like is determined by pressing the color selection button 24, and the color of the LED where the input has been made thereafter becomes the selected color. For erasing characters, etc., all erase 25 and partial erase 2
There are two types: When the all erase button 25 is pressed, all the LEDs on the plate are turned off. In the case of the partial erase 26, the LED of the part where the pressure is applied is turned off until the button is pressed again. By pressing the edit button 27, an operation screen for performing each editing process is displayed on the liquid crystal display.

FIG. 5 shows an automatic editing image of the present invention.
The user selects a plurality of files 29 in the memory,
An image is shown in which the screen size is automatically enlarged / reduced in accordance with the number of designated screens and displayed on the board surface as a list 30.

FIG. 6 is a flow chart showing the operation flow of the present invention. First, turn on the power of the electronic blackboard,
Input and display characters and the like. When the user wants to change the color, the user selects the color 32 and changes the color information 33. Information on the color and position coordinates of characters and the like written on the board surface is automatically saved 37 on the hard disk as needed. Further, according to the user's request, it is also possible to perform storage in the FD, transmission by FAX or mail, printing, and the like. Finally, by turning off the power, the information on the hard disk is cleared.

[0013]

According to the present invention, information input / display means for electronically inputting and displaying characters and figures, information storage means for storing such information in a memory as image data, and information written on a blackboard as required It is possible to provide an electronic blackboard having information automatic editing / output means capable of performing editing, printing, mailing, and facsimile transfer.
