6. No. copy key 407 to print text images
, and a clear key 4 for clearing the data in the internal memory.
It is equipped with 08.

FIG. 4 shows a block diagram of the entire system.

Note that here, one terminal 2 is used as a representative. In addition to the above, this terminal 2 is provided with an LCD driver 204 that drives an LCD panel 201, and a digitizer 2.
An interface controller 205 for the recording pen 203 and the recording pen 203 is provided. Furthermore, the recording pen 203
is provided with an image writing on/off switch 203a and an image erasing switch 203b.

The computer 3 part is a CPU 301 that controls the whole
, a CRT controller 302 that controls the video signal,
A display i? consists of a RAM2O3 that temporarily stores character image data, an interface 304 that inputs and outputs control signals, and an LCD for the operator (moderator). 530
Contains 5. The display 305 displays the content controlled by the keyboard 4, and the content displayed on the LCD panel 201 described above is also displayed at the same time.

Now, in this electronic conference system, the main routine shown in FIG.
Writing and erasing of character images are performed.

That is, when writing, by manually inputting a character image to the digitizer 202 with the recording pen 203 of the terminal 2, the input screen is displayed on the own LCD panel 201, and also simultaneously displayed on the LCD panel 201 of another terminal. Furthermore, the video projector 7 can also display the image. Moreover, this displayed image can also be deleted.

First, for writing, press the switch 20 of the recording pen 203.
Turn off both 3a and 203b and turn off digitizer 2.
02, the writing address is detected by the digitizer 202, the address is read into the computer 3 via the interface controller 205, and the read written content (character image) is transferred to the RA.
Once stored in M2O3, the LCD driver 2
04 and is displayed on the LCD panel 201.

For erasing, turn on the image writing on/off switch 203a of the recording pen 203 while pressing the digitizer 2.
02, the image while the switch 203a is on is displayed on the panel 20 by reading the write address.
1 is displayed, and when the switch 203a is released and turned off, the contents written while the switch 203a was turned on are erased. Furthermore, if the user traces along the image already displayed on the panel 201 with the recording pen 203 while pressing the erase switch 203b, the traced portion of the image is erased by reading the erase address.

Therefore, conference participants use the digitizer 20 of their own terminal 2.
2 and the LCD panel 201 can be used as a blackboard to freely input and output characters and images to proceed with the meeting. Furthermore, by projecting the conference content using the video projector 7, people other than the participants sitting near the terminal 2 can also know the conference content.

Furthermore, the image of the content written in the above manner can be enlarged, reduced, and returned to the original size using the enlargement key 402, reduction key 403, and same-size key 404 of the keyboard 4. Therefore, it becomes easy to examine the drawing in detail or grasp the gist of the drawing.

Each processing routine in the main routine shown in the upper part of FIG. 5 has contents as shown in FIGS. 6(a) to 6(d). First, in the case of screen loading [FIG. 6(a)], the registered file of character images stored in the external storage device 5 is displayed, the ID of the desired file is entered manually, and the file is saved in the computer 3. The file image is read into the RAM 303. In this case, the load key 405 on the keyboard 4 is operated.

Therefore, at the time of a meeting, it is possible to easily present drawings prepared in advance on each person's panel, and to enlarge the main part of the drawing, or to reduce the entire size on a large screen to make it easier to see (
You can also.

In addition, in the case of screen saving - [Figure 6 (b)], the character image created as described above is displayed as it is, or after image conversion such as enlargement or reduction as described above, the registered file is displayed. File [D] is input, and if the file already exists, the input is confirmed and then stored in the external storage device 5. In this case, the save key 406 on the keyboard 4 is operated.

Therefore, all the contents decided at the current meeting can be easily stored for a later meeting or another group's meeting.

Furthermore, in the case of hard copy [Figure 6 (C)], the LCD
This can be done for the image displayed on the panel 201 or the image that has already been saved.

In this case, the hard copy key 407 on the keyboard 4 is operated.

Furthermore, the images stored in the RA '4303 are cleared by operating the clear key 408 [Figure 6 (d)] Figure 7 (a) shows the input and output of the system described above ( (display) part. 7' is, for example, CR
This is a centralized display section using T. Each person's character and drawing great person output terminal 2 exchanges data with other terminals 2, and at that time, not only the data from the other terminal is displayed on the input display section of the own terminal, but also the input is also displayed in a way that overlaps with input from other sources. This also applies to a system configured only with the terminal 2 as shown in FIG. 7(b).

In addition, in the above, the LCD panel 201 that displays character images
is provided in each terminal 2, but this may be a common one, and the terminal 2 may be provided with only character image input means such as a digitizer 202 and a recording pen 203 for inputting characters and images.

〔Effect of the invention〕

As described above, according to the present invention, since it is configured to have a character image display section and a character image input means for each person, necessary matters that were conventionally written on a blackboard can be displayed on the character image display section, and also for each person. Since characters and images can be written on the character image input means, problems associated with the use of blackboards can be eliminated, such as delays in meeting time, rewriting drawings and data, enlarged drawings, and reduced drawings. It is possible to eliminate all the difficulties in the discussion.
