This input display control circuit 31 scans each of the X electrodes 25 and Y electrodes 26 of the transparent touch panel 22 of the display board 2 to detect a specified coordinate position, and sends a detection result of the specified coordinate position and a state signal of the erase detection switch 27. Based on this, writing and erasing control is performed to put the display dots of the liquid crystal display panel 21 corresponding to the designated coordinate positions into a display state or a non-display state.

Further, this input display control circuit 31 is connected to the personal computer 15. Process input information from the card reader 1 and floppy disk device 17.

The captured image information is written into the display memory 33 as display data and displayed on the liquid crystal display panel 21.

Furthermore, this input display control circuit 31 has one display memory 33.
The display data written on the display board 2 is read out and output to the printer 11, and the content displayed on the display board 2 is controlled to be printed out.

Next, the operation of this embodiment configured as described above will be explained with reference to FIG. 5 and subsequent figures.

First, the write/erase control executed by the input display control circuit 31 will be explained with reference to FIG.

In this write/erase control process, first, the X electrode 25 and the Y electrode 2 attached to the transparent touch panel 22 of the display board 2 are
6 are sequentially scanned to determine whether there is an input (coordinate position where the X electrode 25 and Y electrode 26 are in contact).

If there is an input, the state of the erase detection switch 27 is checked to determine whether it is a write mode or an erase mode.

At this time, if the erase detection switch 27 is in the ON state and the writing mode is set, it is determined whether the size of the area (f writing area) that is pressurized at the same time is the size of a predetermined setting area. This determination process is a process for invalidating the writing input when the user accidentally presses the display board 2 with his/her hand or the like.

Therefore, if the size of the writing area is less than the size of the setting area, it is determined that the writing is normal and the transparent touch panel 2
Display data is written to the address of the display memory 33 corresponding to the input coordinate position of 2, and the corresponding display dot of the liquid crystal display panel 21 corresponding to the input coordinate position of the transparent touch panel 22 is brought into a display state.

On the other hand, if the erase detection switch 27 is in the erase mode with the OFF state, the hidden data is written to the address of the display memory 33 corresponding to the input coordinate position of the transparent touch panel 22, and the hidden data is written to the address of the display memory 33 corresponding to the input coordinate position of the transparent touch panel 22. The corresponding display dots of the liquid crystal display panel 21 corresponding to the dots are made to be in a non-display state.

Therefore, by writing while pressing the eraser 7 on the transparent touch panel 22 of the display board 2 with the pen S while placing the eraser 7 on the eraser receiving part 8, the written (pressed) coordinate position is input to the display control circuit. 32, the writing mode is determined, and the portion of the liquid crystal display panel 21 corresponding to the portion written with the pen 9 becomes a display state, and the written content is displayed on the display board 2.

On the other hand, at this time, the eraser 7 is
By lifting up the transparent touch panel 22 of the display board 2 with the eraser 7, the coordinate position of the pressed part is taken into the input display control circuit 31, and the erase mode is determined and the liquid crystal display panel The part corresponding to the part pressed by the eraser 7 of 21 becomes a non-display state, and the part pressed by the eraser 7 of the contents displayed on the display board 2 is erased.

In this way, it is possible to write by hand on the display board 2, and also to erase a part of the display content already displayed on the display board 2 using the eraser 7.

In this case, the writing mode is automatically switched to the erasing mode by lifting the eraser 7 from the eraser receiving part 8, so the writing mode and the erasing mode can be switched without operating the -- switch etc. In addition to improved performance, erasing can be done in the same way as using a conventional blackboard eraser, and since it is cordless, there is even less resistance for the user when erasing.

Next, a key manual check process for checking the state of the keys on the operation panel 6 executed by the input display control circuit 31 will be described with reference to FIG. 6.

In this key manual check process, the state of each key provided on the operation panel 6 is checked, and a process corresponding to the pressed key is performed.

That is, when the format key F1 is pressed, the format data of the minutes is read from the floppy disk 13 loaded in the floppy disk device 17 including a floppy disk drive (FDD), a floppy disk controller (FDC), etc. For example, as shown in FIG. 7, formats 1 to 1 of the minutes are displayed.

Also, when the format key F2 is pressed,
Format data of vertical writing lines is read from the floppy disk 13 loaded in the floppy disk device 17, and the format of the vertical writing lines is displayed, for example, as shown in FIG.

Further, when the format key F3 is pressed down, the format data of the horizontal writing line is read from the floppy disk 13 loaded in the floppy disk device 17, and the horizontal writing line format data is read, for example, as shown in FIG. Show format.

Furthermore, when the format 1 key F4 is pressed, the grid format data is read from the floppy disk 13 loaded in the floppy disk device 17 and the format of the grid is displayed as shown in FIG. 10, for example. do.

Regarding each of these formats, for example, formats 1 to 1 for minutes are available in different formats depending on the type of meeting, etc., and for vertical writing, horizontal writing, and grids, different spacings are available. In addition to preparing a plurality of formats, it is also possible to provide a format update key so that when the format update key is pressed, the formats next to the currently displayed format 1- are sequentially updated and displayed.

In this way, you can select and display more formats without increasing the number of keys.

It becomes even easier to use.

When the scanner key is pressed, the image scanner 4 is driven and controlled to scan the display board 2, the read information read by the image scanner 4 is read and written to the display memory 33, and the read information is transferred to the liquid crystal display panel. 21.

In this case, the information displayed on the display board 2 is displayed in a superimposed manner. However, it is also possible to provide a mode in which information already displayed on the display board 2 is erased and only read information is displayed.

In this case, when displaying the information read by the image scanner 4 on the display board 2, it may be displayed at the same size, reduced or enlarged, or it may be displayed at the same size and then displayed on the personal computer. Reduce or enlarge using 15 editing keys etc.

It may also be possible to move or partially delete it.

Additionally, when the print key is pressed.

The display data stored in the display memory 33 is read out, and the printer 11 is controlled to print out the contents of the display memory 33.

The contents of the display memory 33 at this time are a combination of information input from the outside and information input by hand, so
You can save your handwritten notes as well.

Furthermore, when the full screen erase key is pressed, 1
All the contents of the display memory 33 are cleared to bring the entire screen of the liquid crystal display panel 21 into a clear state.

The input display control circuit 31 also stores the contents of the display memory 33 in the floppy disk 13 of the floppy disk device 17 when the end of editing is instructed by a predetermined key of the personal computer 15 in a process not shown. This allows the content of meetings and the like to be stored in a paperless manner.

Further, the input display control circuit 31 reads document information stored in the floppy disk 13 of the floppy disk device 17 specified by the personal computer 15 in a process not shown, and displays it on the display board 2.

In this way, this information board has a small display board with a transparent touch panel attached to the front of the flat display panel, so it is possible to input by hand, and it is also possible to display documents that have already been created. For example, in a meeting or the like, there is no need to prepare a transparent film sheet or the like in advance as in the case of an overhead projector, and the time required for preparation can be reduced.

Moreover, this information board has an eraser used to erase the display on one display board.

It detects whether the eraser is in use or not, and switches between the penetrating mode and the erasing mode depending on the detection result, so it can be used in the same way as a normal blackboard.

In the above embodiments, an example in which a liquid crystal display panel was used as a flat display panel was described, but in addition, for example, an electroluminescent (EL) display panel, an electrochromic display (
ECD) panels etc. can also be used.

Furthermore, in the above embodiments, an example was described in which a conductor type transparent touch panel was used, but in addition, for example, a photoelectric type transparent touch panel can also be used.

Furthermore, if you have a stationary image scanner, for example,
The original can be displayed without pasting it on the display board.

Sarashiji again. In the above embodiment, an example was described in which the display board was a stationary type, but it can also be made into a handy type so that the user can carry it.

Further, by using a flat display panel capable of color display, monochrome or full color display can be achieved.

As explained above, according to the present invention, the information board can be made multi-functional and the ease of use can be improved.
