FIG. 3 shows the control circuit of the above-mentioned electronic display 3, which is controlled by the built-in CPU 51, which is controlled by the ROM 5.
In addition to controlling each circuit device according to the program stored in R 2, the data input from the handwriting input device 4 is
The input data stored in the RAM 53 is temporarily stored in the RAM 53, and the input data stored in the RAM 53 is decoded to drive and control the display drive circuit 54 to control the display of the electronic display 3.

The above-mentioned ROM 52 includes a JIS standard character data table 52a that associates code numbers with character data for display, and a control table 52b for controlling movement or change of display patterns and deciphering symbols. A character table 52c having predetermined display patterns such as graphics and text messages as display data is stored therein.

Assuming that the illustrated embodiment is configured as described above, a method of operating the handwriting input device 4 will be described below.

As shown in FIG. 1, after connecting the handwriting input device 4 to the electronic display 3, turn on the power switch 17 of the handwriting input device 4.
to enter the standby state where input is possible.

Next, as an input example, a case will be described in which "new release" is entered in double-width by using the JIS code on channel "6".

First, the number "6" is handwritten on the entire input surface of the input panel 15 of the handwriting input device 4 using the input pen 14, and then the edit key 19 of the operation panel 16 is pressed to input the written data into the electronic display 3. Then, CPU 5 1
+i write data R O M 5 2 1. : At the same time as storing it, based on the control table 52b of the ROM 52, it is decoded that the write data is data specifying the "6" channel, and input to the channel "6" provided in the RAM 53. Remember that it is data.

Next, press the symbol key 24 and display the input panel 15 "r times".
If you specify the double angle of the entire display content by inputting this "r times" mark with a pen touch using the input pen 14, as shown in FIG. "double" characters are displayed.

Next, after pressing the LCD clear key 23 to erase the characters on the input panel 15, write a capital letter A in the lower right corner of the input panel 15 as a control symbol to move the display content on the next screen from bottom to top, and press the English letter key. 34 is pressed to input the write data, the CPU 51 decodes it as raJ based on the control table 52b of the ROM 52, and writes the character raJ in the center of the upper surface of the display screen 9, as shown in A of FIG. indicate.

Next, press the symbol key 24 to display rJIs on the input panel 15.
After displaying the J mark and inputting this rJ I SJ mark with a pen touch using the input pen 14, each character code corresponding to "New", "R", and "Middle" is entered.
J r4 8 2 FJ r4 7 6 4J
When inputted sequentially by hand over the entire input surface of the input panel 15 using the input pen 14, the CPU 5 1 inputs the ROM 52
Based on the character data table 52 a of
Store in AM53.

At the same time, as shown in FIG. 4, if the character code 7 3F37 corresponding to, for example, "new" is input, the characters r3 F 3 7J are displayed on the display screen 9 of the electronic display 3.

In this way, input of each character code corresponding to "Shin", "Hatsu", and "Chū" is completed, and then press the Kanji key 31.
By sequentially pressing , the characters "double", raJ, and "new" are displayed on the upper half of the electronic display 3, and the characters "Dai" are displayed on the lower half of the display screen 9, as shown in C of FIG. The characters ``R Release'' and ``Sell'' are displayed.

Next, when the text end key 22 is pressed and the editing end data is input, the CPU 51 transfers the editing end data to the channel "6".
” and press the end key 21 to exit the editing screen.

The above input operations are performed in the order shown below.

End key 21 When calling up the display contents stored in the above-mentioned channel "6" on the display screen 9, the human panel 15 of the handwriting input device 4
After manually inputting the number r6J corresponding to the channel ``6'', when the display key 18 of the operation panel 16 is pressed, the display contents are displayed on the display screen 9, as shown in Fig. 4-2. Display contents are sequentially displayed according to the program of control symbol a.

In this way, just by adding the software and hardware of the handwriting input device 4 and the software of the electronic display device 3,
Display contents can be input, and input devices and their connections can be simplified.

Furthermore, since the display contents are entered using code numbers with a small number of strokes, such as 0 to 9 and A to F, the input operation is simple.Moreover, since the display device 1 can easily distinguish characters, information and advertisements can be displayed easily. It is possible to easily input complicated display contents such as the above, and one handwriting input device 4 can also be used as an input means for a large number of electronic display devices 3 . . . .

Note that the present invention is not limited to the configuration of the above-described embodiment.

For example, the input examples of the above-mentioned handwriting input device 4 are not limited to the input examples shown in the above-mentioned embodiments, but include kanji,
Display contents that are a combination of numbers, handwritten characters such as hiragana and katakana, JIS standard characters, various control symbols, double-width display, reverse display, half-screen and full-screen characters may be input.

FIG. 5 shows another installation example in which the electric display 3 is attached to the upper end of an upright support pole 36 via a plurality of brackets 37.

When inputting display contents to this electronic display 3, the handwritten input device 4 is connected to the input device connection port 11 fixed to the support pole 36.
By connecting the electronic display device 3 and inputting the necessary display data, the electronic display device 3 is installed at a high place, so the display contents are not obstructed by people, buildings, or other obstacles, and can be easily viewed by many people. It is possible to simultaneously announce the display contents to the users, and it is highly effective as a display device.
