Abstract

PURPOSE:To automatically transcribe a document written previously onto the surface of a blackboard and to automatically erase the image information written on the blackboard by preparing a drawing part which draws the image information inputted from an input part on the blackboard and an erasing part which erases the written image information. CONSTITUTION:The image information on a written drawing, etc., is inputted through an input part 2 and read by an image reader at a drawing part 3. Then the image information is automatically written onto a blackboard 1 by an ink jet printer. While the image information written onto the blackboard 1 is automatically read and printed on a sheet. The printed image information is outputted through an output part 5. When the image information is erased out of the blackboard 1, an erasing part 4 is actuated and the image information is automatically scraped off by a frictional eraser. Thus, it is possible to elimi nate the manual transcribing errors and shorten the transcribing time of the image information. At the same time, and manual erasing time and labor can be omitted for the image information.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic blackboard, and more particularly to an electronic blackboard equipped with image information input means, automatic drawing means, and erasing means.

[Conventional technology]

Conventionally, electronic blackboards have been used in meetings and the like, and when people write on the blackboard with a special writing instrument, the image information written on the blackboard is automatically read and printed on paper. This eliminates the need for meeting participants to transcribe image information from the blackboard, allowing the meeting to proceed more efficiently.

[Problem to be solved by the invention]

The conventional electronic blackboard mentioned above can output the image information written on the blackboard surface, but it is not possible to automatically transcribe documents with errors or omissions on the blackboard surface, so they must be retranscribed manually. However, there is a problem that there is a possibility that the information may be entered incorrectly during transcription.

Furthermore, when erasing image information written on the blackboard surface, there is a problem in that the image information must be erased manually.

An object of the present invention is to provide an electronic blackboard that can automatically transcribe documents that have not been previously written on the blackboard surface, and can automatically erase image information that has not been written on the blackboard.

[Means to solve the problem]

In the electronic blackboard of the present invention, when a user writes on the blackboard surface using a writing utensil, the image information of the written blackboard surface is automatically read and printed on paper. an input section for inputting image information such as, a drawing section for automatically drawing the input image information on the blackboard surface, and an erasing section for automatically erasing the image information on the blackboard surface. ing.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram of an embodiment of the present invention.

The electronic blackboard shown in Figure 1 is blackboard surface 1 on which image information is written.
, an input section 2 for inputting image information such as a drawing that has already been drawn, a drawing section 3 for automatically drawing the input image information on the blackboard surface 1, and an automatic reading of the image information on the blackboard surface 1. , an output section 5 for printing on paper and outputting it, and an erasing section 4 for automatically erasing image information on the blackboard surface 1.

Next, the operation will be explained.

Image information such as already drawn drawings is input from the input unit 2. The input image information is read by an image reader in the drawing section 3 and automatically written on the blackboard surface 1 by an inkjet printer. Furthermore, it is possible to freely add notes to drawings or the like that are not written on the blackboard surface 1 using a special writing instrument. When outputting the image information written on the blackboard surface 1 in this manner, the image information is automatically read, printed on paper, and outputted from the output section 5 as in the conventional technique.

Further, when erasing the image information on the blackboard surface 1, the erasing section 4 is activated, and the image information drawn with the quick-drying ink on the blackboard surface 1 is rubbed off by the friction eraser and automatically erased.

〔Effect of the invention〕

As explained above, the present invention makes it possible to automatically transcribe drawings and the like that have already been drawn onto the blackboard, thereby eliminating manual transcription errors and saving time. have an effect.

Furthermore, by automatically erasing the image information written on the blackboard, it is possible to save the effort of manually erasing it.

Claims (1)

[Claims] When you write on the blackboard surface using a writing utensil, the image information on the blackboard surface is automatically read, and the image information such as a drawing that has already been written is input to the electronic blackboard, which is printed and output on paper. An electronic blackboard comprising: an input section; a drawing section that automatically draws input image information on the blackboard surface; and an erasing section that automatically erases the image information on the blackboard surface.
