consists of kanaki.

Next, the configuration of the electronic circuit inside the notebook-type main body case 11 will be explained using FIG. 2.

In the figure, the key operation signal generated by the operation of the key human power section 14 is CP.
Sent to U 31. This CP LJ 31 performs the l111 control operation of each other circuit, and contains a bank pointer (represented as rBPJ in the figure) 31a that controls the points of the memory section 32, which will be described later, and a point of the character buffer 34, which will also be described later. It is provided with a character pointer (represented as rCPJ in the figure) 31b for controlling and an image pointer (represented as rlPJ in the figure) 31c for controlling the point of the image buffer 35, and performs reading/writing of various data from the memory section 32. In addition, it sends control signals to the tablet control unit 33, inputs and outputs character data to and from the character buffer 34, inputs and outputs image data to and from the image buffer 35, and further inputs and outputs image data to and from the character buffer 34 and image buffer 35. Sends control data instructing data reading. The character buffer 34 holds character data to be displayed on the display section 13, and stores 8 bits per character for 128 characters, that is, Bx12
It has an 8-bit storage section a, and after holding and storing input character data, it transfers it to the data sending section 36 in 8-bit units according to control data from the CPU 31. The image buffer 35 is almost the same, and has a storage capacity for 96 x 64 bits of image data to be displayed, and after storing the input image data, the same CP
According to the control data from U 31, it is transferred to the data sending section 36 in 8-bit units. The data sending section 36 includes an internal buffer memory 36a, and a character buffer 34a.
, character data and image data transferred from the image buffer 35 are temporarily held after logical operations and sent to the display buffer 37. Then, the display unit 13 is driven to display according to the data held in the display buffer 37, and character data and image data are displayed. This display section 13 is composed of a dot matrix of 96 horizontal dots x 64 vertical dots using, for example, a liquid crystal display element, and when displaying character data, one character is 6 dots horizontal x 8 dots vertical, which is 16 characters x 8. It shall be possible to display lines.

On the other hand, the tablet input section 12, which is integrally provided on the display section 13, is connected to the tablet input section 12 by a transparent member via a spacer.
A control voltage is applied from a tablet control unit 33, which is composed of two transparent electrode plates and operates according to control signals from a CPU 31, and when writing pressure is applied to this tablet input unit 12, the pressure position changes. The X coordinate data and Y coordinate data are each sent to the A/D converter 38 as analog voltage signals. The A/D converter 38 is
The input voltage signal is converted into a digital value with a resolution of approximately 384 dots in the X coordinate direction and 256 dots in the Y coordinate direction,
The data is sent to the CPU 31 mentioned above.

The operation of the above embodiment will be explained below.

Here, in the schedule mode, the date, time, and location are input as character data, and then a simple map is input as image data using the tablet input unit 12, and these data are input using the rscHEJ key 1.
As an example, we will use an example of an operation in which data is once stored in the memory unit 32 by the operation 7, and then read from the memory as necessary and displayed on the display unit 13.

First, set the input state using the r110J key 22, and then, as shown in FIG.
0'' are entered using the numeric key 20 while separating them using the date key 27.

Then, after operating the "→" key of the cursor keys 23 to input data indicating the schedule contents corresponding to the date, "10:00 Tokyo Station" indicating the time and location is inputted. 10” and “00”, respectively, using the time key 28 and pressing the numeric key 20.
Enter the number with , and then use the keypad 14d to operate ``TOKYO EKI''.

When these manual key operation signals are sent to the CPU 31, the CPtj 31 determines the input data, adds an end code to the R end position, and writes 1 into the character buffer 34. When this character data is sent to the buffer memory 36a of the data sending section 36, held, and outputted to the display buffer 37, as shown in FIG.
The data input to the display section 13 is displayed as shown in FIG.

Next, as shown in FIG. 3(2), a map of the own army is input as image data into the tablet input section 12 integrally provided on the display section 13 using a dedicated pen-shaped writing instrument 39 or the like. The tablet input unit 12 sends each of the X-coordinate data and Y-coordinate data of the pressed position to the A/D conversion unit 38 as analog voltage signals. A/D converter 3
8 converts this into digital value image data and CP
When sent to U 31 , CPU 31 processes this image data as image data to be displayed on display unit 13 and sends the data to image buffer 35 . This image data is sent to the buffer 7 memory 36a of the data sending section 36, held there, and outputted to the display buffer 37, resulting in a written input to the display section 13 as shown in FIG. 3(2). Image data will be displayed in real time.

Next, in order to store and set the character data and image data input above as schedule data, see Figure 3 (3).
), when the rscHEJ key 17 is operated, the CPU 31
executes the input process as shown in FIG. 4, and stores the schedule data in the memory section 32 as shown in FIG.

In FIG. 4, the character pointer 31b is first cleared to "0" in step A01.

Next, in step AO2, the contents of the bank pointer 31a are transferred to the specified file in the memory section 32, in this case the schedule file. Set to . Here, it is assumed that no schedule data has been set in the schedule file in the memory unit 32 yet, and therefore data is stored from the address position immediately after the code rscHEJ indicating the start position of the schedule file in the memory unit 32. shall be.

In the following step AO3, the code rltTJ indicating the beginning of this schedule data is transferred to the address position indicated by the bank pointer 31a of the memory section 32. Next, proceed to step AO4, and change the value of the bank pointer 31a to "+".
1" update setting, the process proceeds to step AO5. In step AO5, it is determined whether the content of the character pointer 31b is greater than its maximum value rl 28J. Since it is still "0" here, the determination result is NO, and the process then proceeds to step AO6. Then, in step AO6, the CPU
31 reads character data "1" from address "0" of the character buffer (CB) 34 according to the value rOJ of the character pointer 31b. In the following step AO7, it is determined whether or not reading of the character data has been completed based on whether or not the read character data is an end code added to the end of the last bale of character data held in the character buffer 34. Here, the judgment result is No, and in the next step AO8, the CPU
The character data “1” read in 31 is stored in memory section 3.
The data is written to the address position indicated by the bank pointer 31a of the schedule file No. 2. Then step A
At O9, the bank pointer 31a is updated and set to "+1". In the following step A10, the character pointer 31
After b is updated by "+1" and set to "1", the process returns to step AO5.

By repeating steps A05 to A10 in this manner, the character data held in the character buffer 34 is stored and set in the memory section 32. When all of the character data held in the character buffer 34 has been stored and set in the memory section 32, this is determined in step AO7, and the process then proceeds to step A11 to perform storage setting in the form of an image.

In step A11, the code r1mTJ indicating the beginning of the image data is set to 1 at the address indicated by the bank pointer 31a of the memory section 32. Next, the process proceeds to step A12, where the value of the bank pointer 31a is updated by "+1", and then the process proceeds to step A13.

In step A13, the image pointer 31C is cleared and set to rOJ, and then step A14 is reached.

In step A14, it is determined whether the contents of the image pointer 31G are larger than its maximum value r768J. Since it is still rOJ here, the determination result is NO, and the process then proceeds to step A15. Then, in step A15, CP
U 31 reads the first 8 bits of image data from address "0" of image buffer (I B ) 35 according to 11 rOJ of image pointer 31C. In the following step A16, the image data read by the CPU 31 is written to the address position indicated by the bank pointer 31a of the schedule file in the memory section 32. Next, in step A17, the bank pointer 31a becomes “+”.
Similarly, in step A18, the character pointer 31b is updated by "+1" and set to "1", and then the process returns to step A14.

In this way, by repeating the processes of steps A14 to A18, the image data held in the image buffer 35 is stored and set in the memory section 32.

Then, when all the character data held in the image buffer 35 is stored and set in the memory section 32 and the value of the image pointer 31c becomes r769J, this is determined in step A14, and the process then proceeds to step A19. In step A19, end data (represented as "ED" in the figure) indicating that the schedule data input settings have been completed is stored in the address position indicated by the bank pointer 31a of the memory unit 32, and this process is thus completed. do.

At this point, the schedule file in the memory unit 32 has the following information:
As shown in Figure 5, the start code of the schedule file rscHEJ, the start code of this schedule data rltTJ, year data "1986", year data delimiter code rYJ, month data "8", month data delimiter load rMJ, day data ``10'', day data delimiter code ``D'', schedule content ``10:00 TOKYO EKI'', code r1mTJ indicating the end of character data and the beginning position of image data, image data 8 dots x 768 minutes, and end code rEDJ. will be stored continuously.

Next, the operation when displaying the data stored in the memory section 32 as described above on the display section 13 will be explained.

After setting the data output state with the rI10J key 22, when the rSCHEJ key 17 is operated, the process shown in FIG. 6 is performed, and the schedule data stored in the memory section 32 is read out and displayed on the display section 13. Ru. The processing will be described below.

In FIG. 6, first, as shown in step BO1, the contents of the bank pointer 31a are set immediately after the first code rscHEJ of the schedule file. Then step BO
At step 2, the CPtJ 31 reads data from the memory section 32 according to the contents of the bank pointer 31a. In the following step BO3, the value of the bank pointer 31a is updated by "+1", and then in step BO4, the above step BO
It is determined whether the data read in step 2 is the code rltTJ. In this case, since the data is the code rltTJ, the determination result is YES, and the process then proceeds to step BO5.

Also, if the judgment result is No, step B again.
The process advances to O2, and the processes of steps BO2 to BO4 are repeated until it is determined that the code is rltTJ.

Now, in step 805, the character pointer 31b
is cleared and set to rOJ. CP according to the contents of the bank pointer 31a updated in the next step BO6.
U 31 receives character data “1” from memory section 32
Read out. After that, in step 307, the bank pointer 3
1a is updated by "+1", and if it is determined in the subsequent step BO8 that the read character data "1" is not the code r1mTJ, the process proceeds to step BO9. and,
At step BO9, this character data "1" is transferred to the address position "0" indicated by the character pointer 31b of the character buffer 34. Thereafter, in step B10, the value of the character pointer 31b is updated by "+1", and then the process returns to step BO6.

By repeating the processes of steps BO6 to BO310 in this way, the character data stored in the memory section 32 is sequentially transferred to the character buffer 34.

Then, all the character data stored in the memory section 32 is transferred to the character buffer 34, and step B
When the code r1mTJ indicating the beginning of the image data following the character data is detected in O8, the process proceeds to step 3.
It reaches 11.

In step B11, the image pointer 31G is cleared to rOJ. In the next step 812, the CPU 31 transfers data to the memory section 32 according to the contents of the bank pointer 31a.
Read the image data starting from. After that, in step B13, the bank pointer 31a is updated by "+1",
In the following step B14, it is determined whether the read image data is the end code rEDJ. If it is determined that the end code is not rEDJ, then step B
15, this image data is transferred to the address specified by the image pointer 31c of the image buffer 35 [rOJ
Transfer to.

Thereafter, in step 316, the value of the image pointer 31G is updated by "+1", and then the process returns to step B12.

By repeating the processes from steps 812 to B16 in this manner, the image data stored in the memory section 32 is sequentially transferred to the image buffer 35. Then, all the image data stored in the memory section 32 is transferred to the image buffer 35, and when the end code rEDJ following the image data is detected in step 814, the process proceeds to step B17.

In step B17, the display buffer 37 is once cleared in preparation for displaying the schedule data. Thereafter, in step 818, the image data held in the image buffer 35 is transferred to the buffer memory 36a of the data sending section 36. Next, in step 319, this buffer memory 3
The image data 6a is further transferred to the display buffer 37. In the following step B20, the character data held in the character buffer 34 is transferred to the buffer memory 36a of the data sending section 36. and,
In the next step 821, the character data in the buffer memory 36a is sent to the display buffer 37, and the character data in the buffer memory 36a is sent to the display buffer 37.
Character data is superimposed (OR-added) on the image data held in 7. Finally, in step 822, the display unit 13 is driven to display according to the schedule data obtained by ff1ff of the character data and image data held in the display buffer 37, and this process is thus completed.
