[Problem to be solved by the invention] In the prior art,
There is no consideration given to reading characters, figures, etc. written on paper and displaying them on the electronic blackboard surface, and people have to write letters, figures, etc. on the electronic blackboard one by one, or input them using keys, so meetings are difficult. There was a problem in that it took a lot of time to write on the blackboard and input keys. To compensate for this, the user (meeting organizer) should manually write the necessary information on the electronic blackboard before the meeting, or copy the information written on paper and distribute it to the meeting participants. Alternatively, the information written on the paper may be copied onto film and enlarged and projected using a projector, etc., to explain the information to the conference participants. There is a problem in that there is a lot of wasted time in preparing the projector device, and furthermore, it leads to the consumption of a large amount of copy paper.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic whiteboard with a drawing mechanism that solves the problems of the prior art described above.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a conventional electronic blackboard device that reads, copies, and outputs information written on a blackboard surface, and provides a method for reading characters written on a paper surface, The present invention is characterized in that it includes means for electrically reading a figure, and means for drawing and displaying the read information on a blackboard surface.

Furthermore, the present invention is characterized in that it includes a means for enlarging the read information, and enlarges the characters and figures written on the paper and prints them on the blackboard surface.

[0007]

[Operation] An image scanner reads paper information, converts it into an electrical signal as image information, and stores it in a memory area determined for each printing range. The stored information is sequentially read out, enlarged if necessary, and then electrostatically recorded on the surface of the electronic blackboard, and developed by adsorbing toner. The electronic blackboard surface is controlled to move by the required amount and then stop.

[0008] In the present invention, the read page information is processed as image information, enlarged and drawn as it is, and since it is not standardized by artificial character fonts or fixed graphic patterns, the input page information is Information can be written in any way, including manual writing and machine writing (word processors, letterpress printing, etc.).

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an external view of an embodiment of an electronic whiteboard with a drawing mechanism according to the present invention, in which (a) shows a front view and (b) shows a side view. The electronic blackboard 100 with a drawing mechanism includes an electronic blackboard surface 10, a copier 11, an image scanner 12, a toner box 13, an operation panel 14, and the like. Although it is hidden and cannot be seen in FIG. 1, there is a drawing mechanism at, for example, the right end of the blackboard surface 10.

FIG. 2 shows an example of the configuration of a drawing mechanism, in which an electrostatic drawing mechanism is shown. In FIG. 2, 20 is a rotating drum of the electronic blackboard 10, 21 is an electrostatic recording head arm, and 2
2 is an electrostatic recording head that moves up and down on the arm 21; 23 is a developer arm; and 24 is a developer that moves up and down on the arm 23.

FIG. 3 is a block diagram showing a configuration related to reading, enlarging, and drawing page information among the control devices built into this electronic whiteboard with drawing mechanism. The control circuit 30 controls the operations of each section in accordance with instructions for drawing, drawing area, enlargement, etc. inputted from the operation panel 14, and reads out page information, enlarges, and draws on the electronic blackboard surface. The processing flowchart is shown in FIG.

[0012] Referring to FIG. 4, a procedure for reading page information, enlarging, and drawing on this electronic blackboard with drawing mechanism will be described below.

First, in step 41, the image scanner 12 reads characters, figures, etc. written on the paper information, converts them into electrical signals as image information, and stores them in the input buffer 31. In step 42, the image information data in the buffer 31 is stored in an area designated for each printing range in the memory 32. Here, the memory 32 corresponds to the electronic blackboard surface 10. In step 43, memory 3
Image information data is sequentially read out from the storage area for each printing range within 2. In step 44, the image information data read from the memory 32 is enlarged to a specified size by the enlarging circuit 33 and stored in the output buffer 34.

In step 45, the enlarged image information data is sequentially read out from the output buffer 34 and printed on the electronic blackboard surface 10 in the following manner. The image information data read from the output buffer 34 is sent to the electrostatic recording head 22.
will be forwarded to. The electrostatic recording bed 22 moves on the electrostatic recording head arm 21 under the control of the control circuit 30 while
The transferred image information data is electrostatically recorded on the electronic blackboard surface 10. Thereafter, under the control of the same control circuit 30,
The electrostatically recorded position on the electronic blackboard surface 10 is moved by the rotating drum 20 to below the developing device 24. The developing device 24 applies (develops) the toner in the toner box 13 while moving on the developing device arm 23 to form an image. This is repeated for one drawing range.

At step 46, when the drawing in one drawing range is completed, the electronic blackboard surface 10 is moved to the next drawing range. In step 47, it is determined whether drawing of all the image information data in the area of the memory 32 has been completed. If not, the process is repeated from step 43, but if all the drawings have been completed, The process moves to the next step 48. In step 48, a production screen is displayed and movement of the electronic blackboard surface 10 is stopped.

Note that the printed electronic blackboard surface 10 is not fixed so that it can be erased with an eraser. In addition, reading the information written on the electronic blackboard surface 10, copying it onto paper using the copying machine 11, and outputting it is the same as in the past.
Explanation will be omitted.

Although one embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to this. For example, in the embodiment, an electrostatic drawing mechanism is shown, but there is no need to limit it to this.

[0018]

As explained in detail above, according to the present invention, it is possible to eliminate the need for humans to spend time copying information such as characters and figures written on a sheet of paper onto an electronic blackboard, and to reduce the amount of information written on a sheet of paper. And it becomes possible to electrically create and display images on an electronic blackboard in a short time regardless of the written content. Further, the information written on the paper can be enlarged to the required size and drawn and displayed on the electronic blackboard, and the characters and figures written on the paper may be small.
