[Problems to be Solved by the Invention]

(1) The conventional device is a batch processing system that draws on the tablet 1 and at the same time confirms that there is no erroneous input information such as characters and figures displayed on its own display unit, and then sends it to the other party. It was not intended to be transmitted and displayed in real time to the other party. Therefore, the operation of the device is troublesome, and it is not suitable for the general public who cannot be a computer or the deaf person.

(2) Since some of the characters / figures drawn on the stylus pen 1a cannot be erased, if an error is made during the input of information, the input must be made again from the beginning, which makes the input work difficult. It was (3) After displaying characters / figures, it is normal to point to one of them and have a conversation or writing. At this time, do not write the position of the stylus pen, but use a temporary pointer mark (○, ×, ←). Etc.) is often desired to be displayed at the point of the stylus pen, but the conventional one was inconvenient because it did not have this function.

(4) In order to input a complicated graphic for displaying and to record the character / graphic information displayed on the display unit 2, it is necessary to write or copy by hand, which is inconvenient. As described above, the conventional device has a problem that it is not easy to use. On the other hand, a facsimile is used for transmitting character / graphic information, but this is, for example, batch processing for each page, and drawing on the graphic is transmitted to the other party in real time.
It is the same as the above-mentioned conventional device that it cannot be displayed or erased.

An object of the present invention is to enable input information such as characters / figures to be displayed in real time not only on a batch basis but on the other party as well as on the other side, and a part of the characters / figures already entered can be deleted. It's easy.In the instruction mode, the position of the stylus pen is not displayed, but a predetermined pointer mark can be temporarily displayed at that point, and when necessary, the characters / figures are read into the display or the display is printed on paper. It intends to provide an instant character / graphics interactive device which can also be used.

[0012]

FIG. 1 shows an embodiment of the present invention. In FIG. 1, parts corresponding to those in FIG. 3 are denoted by the same reference numerals. The device of the present invention uses the stylus pen 1a so that characters and pictures are drawn on paper.
It is displayed on the liquid crystal display part 2 of the user's own body while moving, and is also displayed to the other party at the same time. If you make a mistake in drawing and enter the erase mode, you can trace the wrong line or character with the stylus pen 1a so that the erased part erases it from the display of your own and the other party.
Therefore, it can be used by an ordinary person, a deaf person, etc. with an extremely natural motion.

As shown in FIG. 1, a transparent tablet 1 is superposed on a liquid crystal display section 2. When the tablet 1 is touched with the stylus pen 1a, the coordinate reading circuit 7 detects the X and Y coordinate positions of the stylus pen 1a on the tablet 1 from the sensor information of the pen obtained from the stylus pen 1a at that time, and the detection output thereof. Is a microcomputer 8
Entered in. The microcomputer 8 writes this position data in the screen memory 9 as 1-bit data and transfers it to the transmission control unit 10. The transferred position data is written from the transmission control unit 10 to the screen memory of the partner device via the modem 11 and the telephone line 12 in order. The position data written in the screen memories 9 of the self and the other party are read out under the control of the respective microcomputers 8 and displayed on the same X and Y coordinate positions of the liquid crystal display unit 2 through the display circuit 12.
In this way, the characters / graphics drawn on the tablet 1 by the stylus pen 1a are displayed on the liquid crystal display unit 2 of the self and the partner device in real time.

In order to further improve the usability of this device, writing, erasing or indicating mode keys 14a, 14b, 14c on the tablet 1 (the mode selecting key 14 as a whole)
Is provided and the stylus pen 1a selectively touches any one of them to enable the subsequent operation mode to be input to the microcomputer 8 according to the pen position data at that time. In addition, functions such as local enlargement and reduction can be provided. The microcomputer 8 temporarily stores the mode selection information and transfers it to the microcomputer of the partner device through the transmission controller 10.

When the writing mode is selected, the locus is written in the screen memory 9 while the stylus pen 1a moves as described above, and is displayed in real time on the display section of the self or the other party. If you make a mistake in drawing, enter the erase mode and trace with the stylus pen 1a on the part you want to erase with the stylus pen 1a (line segment, letter or part of letter, part of figure, etc.). The erased previous graphic can be erased from the display unit 2 and the screen memory 9 of itself and the other party, just like the eraser erases that portion.

After displaying a character / figure on the display unit, if one wants to point to that point and proceed with conversation or writing, if the locus of the stylus pen 1a instructed remains displayed for a long time, the displayed figure becomes difficult to see. In such a case, if the pointing mode is selected and the point to be pointed with the stylus pen 1a is touched, the locus of the stylus pen 1a is not displayed, and the touched point is used as a pointer mark, for example. The center of the ○ and × marks and the tip of the ← mark are aligned and displayed temporarily. The pointer mark pattern data is written in the pointer mark memory 17 in advance, is controlled by the microcomputer 8, and is read and displayed. That is, it is realized by superimposing the image signal obtained by scanning the pointer mark on the main scanning image signal before and after the scanning raster of the display screen corresponding to the position of the stylus pen 1a and the position on each raster. However, this pointer mark is for display only and is not written in the screen memory 9.

The transmission controller 10 includes a microcomputer 8 and a modem 1.
1, various transmission / reception control including conversion of parallel type signals on the microcomputer side and serial type signals on the modem side, error control of data signals, and input / output control with the microcomputer (input / output unit) Known control is performed.
The modem 11 converts (modulates) a digital-format data signal into an analog signal suitable for the transmission path, and performs inverse conversion (demodulation) thereof.

In this example, the telephone section 6 is further connected to the modem so that telephone transmission and character / graphic transmission (data transmission) can be switched by time. When the device is used by the general public, not the deaf, data transmission and reception is heard, during which the parties interrupt the conversation. Alternatively, the transmission control unit 10 may control the modem 11 at the time of data transmission to cut off the voice from the telephone unit, or the transmission control unit 10 temporarily stores the data during the call and the voice is cut off. You can also send and receive data.

The voice transmission and the data transmission can be simultaneously performed in parallel as seen from a human sense. There are various methods for that purpose, one of which is, as shown in FIG. 2, a transmission voice signal input from a transmitter (microphone) in the transmission control unit 10 is converted into a digital signal through the A / D converter 21. After the conversion, if necessary, the information compressor 22
To the time-division mixer 23. In addition, the transmission data SD input from the microcomputer 8 is input to the time division mixer 23 through the information compressor 24 as needed, and mixed with the transmission voice signal component, for example, a medium speed modem of 1.6 to 14.4 kbps. 11 to the telephone line 12.

On the other hand, the received data obtained from the modem 11 is separated into a voice component and a data component by the time separator 26, and the voice data is passed through the information expander 27 as necessary, and then the D / A converter 28. Is converted into an analog signal and supplied to the receiver (speaker). Further, the time-separated data signal is converted into reception data RD through the information expander 29 as necessary and supplied to the microcomputer 8. Although a clock is supplied to each of these functional blocks from a clock circuit, they are not shown.

As shown by the dotted line in FIG.
The transmission figure reading section 31 and / or the recording section 32 of the AX are connected to read a complicated figure / sentence or the like to be transmitted, and the read figure data is written in the screen memory 9 and displayed on the liquid crystal display section 2. You can give instructions on the displayed screen,
It is possible to interact by adding or deleting. The display graphic thus obtained is printed on paper by the recording unit 32 as necessary.

The portion indicated by the reference numeral 20 in FIG. 1 constitutes a transmission / display control unit, and performs transmission control, display control, etc., as can be understood from the above description.

[0023]

As described above, according to the present invention,
Input information such as characters and figures can be displayed in real time not only to the user but also to the other party. When the erasing mode is selected as the tablet input information, it is possible to erase the designated portion of the characters / graphics already stored and displayed. By providing the instruction mode as the tablet input information, it is possible to temporarily display a predetermined pointer mark at the point pointed by the stylus pen 1a without storing the point. When the device of the present invention is provided with a conventional telephone function, it becomes possible for a general person to use a convenient conversation by voice and characters / graphics. F
When the reading unit 31 and the recording unit 32 of the AX are provided together, a complicated figure / sentence, etc. is displayed, and an instruction is given on the display screen, and additional writing or erasing is performed for dialogue, and if necessary, on a sheet of paper. It can also be printed.

As described above, according to the present invention, the usability of the character / graphics transmission device can be greatly improved as compared with the prior art. It can also be used for writing deaf people.
