That is, when the "input" key 15b of the key input unit 15 is operated, the character input process in FIG. 5 is started, the contents of various registers in the RAM 23 are cleared and initialized, and the input to the touch panel 14 is performed. -The display waits (steps S1 and S2).

In the present embodiment, it is assumed that the key input state data is initially set in the input state register 49 in the RAM 23, and the input area 14a of the touch panel 14 is shown in FIG.
As shown in (A), the keyboard K is displayed to enter the standby state. Then, when the input area 14a is touched, the mode at that time is determined, and the process shifts to the key input process in FIG. 6 (step S3 → SA).

In this key input processing, the keyboard K
When the character keys of are touch-operated and, for example, "COME" is input, each key "C""O" is input.
Character codes corresponding to "M" and "E" are sequentially stored in the input code character buffer 41 in the RAM 23 (steps A1 → A2).

Then, the character code data input by the key is sequentially transferred to the actual data memory area 46b in the output information area 36 and stored and updated, as shown in FIGS. 4B and 4C. The attribute data "code", pointer data "P1", and data length "4" are stored in the management data area 46a (steps A3, A).
4).

The attribute data indicates whether the input data is handwritten or a key code. In the case of key input, a "code" is stored. The pointer indicates the start address of the actual data memory area 46b in which "COME" is stored.

The data length stored in the management data area 46a indicates the storage length of the data. If the character code requires 8 bits per character, and the data length is managed in byte units, the data length of the management data area 46a is "C" → "O" →
Every time "M" → "E" is input, "1" → "2" →
It is updated as “3” → “4”.

Thus, when the key data "COME" is sequentially input, the output process in FIG. 7 is performed each time (step SA → SB). In this output processing, first, the display work area 50 in the RAM 23 is cleared and initialized, and the key data "COME" stored in the actual data memory area 46b of the output information area 46 is stored.
Is read according to the pointer data "P1" managed in the management data area 46a, and its attribute data is determined as "code" (step B1,
B2, B3).

Then, the key data "CO" read from the actual data memory area 46b of the output information area 46 is read.
“ME” is sequentially developed as a code character into a font pattern, written in the display work area 50, and displayed in the output area 14b of the touch panel 14 (steps B3 → B4a, B5 → S2).

In this way, when the key data "COME" is input and displayed and the "space" key 34 is operated, the key input processing in FIG. 6 is performed (steps S3 → S
A), the character code "COME" stored in the input code buffer 41 is cleared, and the word value of the total word number register 47 is incremented (+1) and set to "1" (steps A1 → A5 → A6, A7).

As a result, "COME" is fixed as one word. After that, when "TO" is entered on the keyboard K displayed in the input area 14a to display it in the output area 14b, and the "Space" key 34 is used to perform a word-by-word segmentation operation, the same as the above-described figure is displayed. 6
The character code corresponding to the key data “TO”, its attribute data “code”, pointer data “P2”, and data length “2” are stored in the output information area 46 through the key input processing in FIG. At the same time, the word value of the total word number register 47 is updated and set to "2".

When the "BS" key 32 is operated to delete the key data input and displayed by operating the keyboard K, the backspace processing in FIG. 11 is performed (steps S2 → S3 → SC). ).

In this backspace processing, when it is determined that the keyboard K is in the key input display state based on the input state data stored in the input state register 49, the writing indicating the writing position of the input code character buffer 41 is performed. Whether or not the writing is in progress is determined depending on whether or not the pointer is at the head (step C1 → C2).

If, for example, "COME"->(space)->"TO" is input and the "BS" key 32 is operated, the "space" key 34 is not used to separate word by word. Therefore, it is determined that the data is being written in the input code character buffer 41, and only the code data of the final character "O" stored in the input code character buffer 41 is deleted. Also,
At the same time, correspondingly, only the key data "TO" stored in the pointer P2 of the actual data memory area 46b in the output information area 46 is deleted only "O", and further stored in the management data area 46a. The data length “2” is also rewritten to “1” (step C2 → C).
3, C4).

Then, through the output processing (steps B1, B2, B3 → B4a, B5) in FIG. 7, the key data "COMET" is expanded in the display work area 50, and the output area 14b is expanded. "COMET" in which only the last input key data "O" is deleted is displayed (step SB → S2).

On the other hand, for example, after inputting “COME” → (space) → “TO” → (space), “B”
When the "S" key 32 is operated, it is determined that the input code character buffer 41 has been cleared and the write pointer has been returned to the head because the word is delimited by one word, and the output information area 46 is returned. The final key data “TO” stored in the pointer P2 of the actual data memory area 46b in FIG. 2 is deleted in units of one word (character string), and the attribute data “code” and pointer stored corresponding to the management data area 46a The data “P2” and the data length “2” are also deleted (step C2 → C).
5).

Along with this, the total word number register 47
The word value of (1) is rewritten to "1" (step C6). Then, through the output processing (steps B1, B2, B3 → B4a, B5) in FIG. 7, the key data “COME” is expanded in the display work area 50, and the final input character is displayed in the output area 14b. Row "T
“COME” from which “O” has been deleted is displayed (step SB → S2).

On the other hand, by touching the keyboard K and inputting "COME" .fwdarw. (Space) .fwdarw. "TO" .fwdarw. (Space) and displaying in the output area 14b,
Next, when the "switch" key 31 is operated to input the handwritten character data, the handwriting input board P is displayed in the input area 14a of the touch panel 14 as shown in FIG. The state is set (steps S3 → S4 → SB → S2).

When the input area 14a is touched, it is determined that the handwriting input board P is in the handwriting input state, and the process proceeds to the handwriting input process in FIG. 8 (step S3 → SD).

In this handwriting input process, for example, “M” is input to the handwriting input board P with a touch pen.
When handwriting inputting "y", the locus accompanying the handwriting input is sampled as coordinate data (x, y) at a constant cycle. At that time, it is constantly judged whether or not the pen is released and the input position exceeds the scroll start line L. When the input position exceeds the scroll start line L, "1" is set in the scroll flag register 44. (Step D1 → D2 → D3).

Further, the coordinate data (x, y) sampled in accordance with the handwriting input is R only for the x coordinate.
Scroll width and RAM pre-stored in OM22
Correction is made based on the number of times of scroll processing stored in the scroll number register 45 in 23 (step D4).

Incidentally, since the scroll start line L is not exceeded while the handwritten data "My" is being input,
Since the scroll flag is not set and the scroll number register 45 is set to "0", the coordinate data (x1, y1) of the input loci sequentially sampled.
) (X2, y2) ... (xn, yn) are not substantially corrected. Then, only when the input current coordinates are compared with the previous coordinates and it is determined that they are different, the newly updated coordinate data are sequentially written in the handwriting buffer 4 in the RAM 23.
It is stored in step 2 (steps D2 → D4, D5 → D
6).

Then, each coordinate data (x1, y1) (x2, y2) stored in the handwriting buffer 42 is ...
The line segment image data connecting (xn, yn) is sequentially written in the echo back display buffer 43, and the locus of "My" accompanying the handwriting input is drawn and displayed on the handwriting input board P ( Step D7 → S5).

Then, when the handwriting data "My" is handwritten and the touch pen is separated from the handwriting input board P, no input coordinate data is sampled and it is judged whether the pen has been separated last time. It is determined whether or not the scroll flag “1” is set in the scroll flag register 44 (steps D1 → D8 → D9).

In this case, since the scroll flag is not set at the time when "My" is input by handwriting, each coordinate data (x1, x1) of the handwritten data "My" is input.
Following y1) (x2, y2) ... (xn, yn), the pen release code (FF, FF) is stored in the handwriting buffer 42 (steps D9 → D12).

Further, in this handwriting input process, as in the above case, the "Official" is set for the handwriting input board P.
When "O" of "e" is input by handwriting, if it is determined that the input position exceeds the scroll start line L, "1" is set in the scroll flag register 44 (steps D1 → D2 → D3). ).

While the handwriting data "O" is being input, the scroll flag is set, but the scroll count register 45 is still set to "0". Therefore, the coordinate data of the input loci sequentially sampled. (Xn + 1, yn + 1) (xn + 2, yn + 2) ... (xm, y
m) is not subjected to substantial correction, and only newly updated coordinate data determined to be different from the previous coordinate and the current coordinate is sequentially stored in the handwriting buffer 42 in the RAM 23 (steps D2 → D3). D4, D5 → D6).

Then, each coordinate data (xn + 1, yn + 1) (xn + 2, y) stored in the handwriting buffer 42 is stored.
n + 2) ... (xm, ym) line segment image data are sequentially written in the echo back display buffer 43, and the locus of "O" accompanying the handwriting input is the handwriting input board P.
It is drawn and displayed above (step D7 → S5).

When the handwriting data "O" is handwritten and the touch pen is separated from the handwriting input board P,
The RAM is sampled when the pen separation is sampled.
Since it is determined that the scroll flag “1” is set in the scroll flag register 44 in 23, RA
The scroll number stored in the scroll number register 45 in M23 is read out, and it is determined whether or not the maximum possible number of scroll processes stored in advance in the ROM 22 is exceeded (steps D1 → D8 → D9 → D10). .

In this case, the scroll count register 4
Since the number of times of scroll processing stored in 5 is “0”,
It is determined that the maximum number of times (3 times) of the scroll processing has not exceeded, and the echo back display buffer 43
The display range of the handwritten image data written on the handwriting input board P is scrolled according to a predetermined scroll width stored in the ROM 22 in advance. At the same time, the scroll count value in the scroll count register 45 is set to (+1) and set to "1", and the scroll flag register 44 is reset to "0" (step D10 → D11).

Then, each coordinate data (xn + 1, yn + 1) (xn + 2, yn + 2) ... (xm, of the handwritten data “O”)
ym), the pen release code (FF, FF) is stored in the handwriting buffer 42 (step D12).

Next, as shown in FIG. 3C, when "ffice" is handwritten input following the handwriting data "O", the respective coordinate data and pen separation are performed according to the same handwriting input process as described above. The code is stored in the handwriting buffer 42. Then, line segment image data connecting the coordinate data is sequentially written in the echo back display buffer 43, and the handwritten input board P scroll-displayed.
Following the above handwritten data "O", "ffice" is displayed.

In this case, each coordinate data stored in the handwriting buffer 42 in correspondence with the handwritten data "ffice" after the scroll processing is the scroll number value "1" stored in the scroll number register 45 and the ROM.
Since the x-coordinate is corrected based on a predetermined scroll width stored in advance in 22, the handwriting data “ffice” after the scroll processing is compared with the drawing position of the handwriting data “My” before the scroll processing. Drawing positions do not overlap.

Thus, according to the handwriting input process (step SD) and the echo back display process (step S5), as shown in FIGS. 3B and 3C, the handwriting data "My Office" is displayed on the handwriting input board P. When the input operation is performed by handwriting and the input locus is displayed, and a delimiter operation is performed in units of one word with the "Space" key 34, the handwriting / output conversion processing in FIG. 9 is performed (step S3 → SE).

In this handwriting / output conversion process, first, the handwriting data "My stored in the handwriting buffer 42 in the RAM 23 is stored according to the handwriting input process in the handwriting input board P on the input area 14a of the touch panel 14.
Coordinate data (x1, y1) corresponding to "Office"
) (X2, y2) ... Is converted into relative coordinates corresponding to the output area 14b as shown in FIG. 10 (step E1).

That is, the coordinate data (x1, y1) (x2, y2) ... Corresponding to the handwritten data are coordinates with the upper left end of the tablet 13 as the origin, and these are respectively expressed by the following formula (1). Is converted into relative coordinates with the left end of the output area 14b as the starting point Q (0,0)
Each coordinate data of the handwritten data after the coordinate conversion is stored in the handwriting buffer 42 again.

[(X−Xmin), (y−Ymin)] Equation (1) Also, together with this, the output information area 46 in the RAM 23.
As shown in FIG. 4B, the attribute “handwriting” and the pointer “P” of the handwritten data “My Office” delimited by the word unit are stored in the management data area 46a in FIG.
3 ”and data length“ 60 ”are written (step E
2).

In this case, the handwritten data "My Of
The data length "60" of "fice" indicates that the series of coordinate data stored in the handwriting buffer 42 is written over 60 bytes.

The series of coordinate data of the handwritten data stored in the handwritten buffer 42 is shown in FIG.
As shown in (C), the contents are transferred to the actual data memory area 46b in the output information area 46, the contents of the handwriting buffer 42 are cleared, and the contents of the echo back display buffer 43 are also cleared (step E).
3).

Then, the word value stored in the total word number register 47 is incremented by (+1) and updated to "3" (step E4). Thus, the handwritten data "My Off
The relative coordinate data corresponding to “ice” is stored in the actual data memory area 46b of the output information area 46, and its attribute, pointer, and data length are written in the management data area 46a, and the whole word numerical value is updated. Then, Fig. 7
Then, the output processing in step S3 is performed (step SE → SB).

In this output processing, the display work area 50 in the RAM 23 is initialized and the output information area 4 is set.
The handwritten data “My Office” stored in the actual data memory area 46 b of the management data area 46 of FIG.
The attribute data is read according to the pointer data "P3" managed in a and its attribute data is determined as "handwriting" (steps B1, B2, B3).

Then, the handwritten data "M" read from the actual data memory area 46b of the output information area 46 is read.
The series of coordinate data constituting "y Office" is corrected to coordinate values according to the ratio of the input height a of the input area 14a and the output height b of the output area 14b according to the following formula (2), and the display work area It is developed and written in 50, and as shown in FIG. 3 (D), it is displayed in the output area 14b following the key data "COME TO" (steps B3 → B4b, B5 → S2).

(X, y) ← [{x × (b / a)}, {y × (b / a)}] Equation (2) On the other hand, the handwriting input board P is operated during the handwriting input process. Then, when the user wants to delete the handwritten data echo-displayed on the handwriting input board P, or after the word-by-word division operation by the "Space" key 34, the coordinates are converted and displayed on the output area 14b. If you want to delete the handwritten data, select "B
When the "S" key 32 is operated, the process moves to the backspace processing in FIG. 11 (steps S2 → S3 → SC).

In this backspace processing, when it is judged that the handwriting input board P is in the handwriting input display state based on the input state data stored in the input state register 49, the writing indicating the writing position of the handwriting buffer 42 is performed. It is determined whether the pointer is at the head or in the middle of writing (step C1 → C7).

Here, for example, FIG. 3 (B) and FIG.
As shown in (C), if the "BS" key 32 is operated during the handwriting input of "My Office", the space operation of the "Space" key 34 is not performed for each word. It is determined that the writing pointer of 42 is in the middle of writing, the coordinate data sampled corresponding to the handwriting input position immediately before that is deleted from the handwriting buffer 42, and the writing pointer of the handwriting buffer 42 becomes (-1 ) (Step C7
→ C8).

Then, the last line segment image data of the handwritten data echo-displayed based on the deleted coordinate data in the handwriting buffer 42 is redisplayed in a deleted state (step C9 → S
2).

On the other hand, for example, as shown in FIG. 3D, after inputting "My Office" by handwriting, the "Space" key 34 is used to perform a word-by-word division operation, and then the "BS" key 32 is touched. Then, the handwritten data is displayed in the output area 14b, the handwriting buffer 42 is cleared, and the pointer is returned to the head. Therefore, the handwritten data is stored in the pointer P3 of the actual data memory area 46b in the output information area 46. The final handwritten data "My Office" is deleted in units of the one word (character string). Then, the attribute data “handwriting”, the pointer data “P3”, and the data length “60” stored in correspondence with the management data area 46a are also deleted (steps C7 → C5).

Along with this, the total word number register 47
The word numerical value of (1) is rewritten to "2" (step C6). Then, after the output process in FIG. 7, the key data “COM
Only "E TO" is expanded, and "COME TO" in which the final input character string "My Office" is deleted is displayed in the output area 14b (step SB → S).
2).

On the other hand, as shown in FIG. 3D, the handwritten data "My Office" is displayed in the output area 14b.
When the "switch" key 31 is operated again to input the character data by the key operation in the state displayed on the screen, the keyboard K is displayed again in the input area 14a of the touch panel 14, and the key input waiting state is entered. (Steps S3 → S6).

Then, based on the input state data stored in the input state register 49 in the RAM 23, it is determined that the keyboard K is in the key input state, and the key input process in FIG. 6 is performed again (step S3). →
SA).

Up to this point, the input of key characters by the keyboard K has been described, but instead of the keyboard K, a fixed phrase menu display can be used. For example, if you add a handwritten character such as "10 o'clock" or "Shibuya" after calling this fixed phrase as "Meeting," as the fixed phrase, you can compose a message with simple effort and send it to the other party. can do.

Therefore, according to the portable information communication device equipped with the input device having the above-mentioned configuration, when the key data is input by operating the keyboard K displayed in the input area 14a of the touch panel 14, the respective character code data is obtained. The attribute, the storage pointer, and the data length are stored in the actual data memory area 46 in the output information area 46 in the RAM 23, and the management data area 46a is written with them.
When the handwriting input board P displayed in the input area 14a is operated to input handwritten data, coordinate data sampled at a constant cycle corresponding to the input locus is stored in the actual data memory area 46. At the same time, its attributes, storage pointer, and data length are written in the management data area 46a. Based on the actual data stored in this output information area 46 and its management data, the key data consisting of the character code and a set of coordinates are formed. Since the handwritten data consisting of the image data to be displayed is also displayed in the output area 14b of the touch panel 14, the code character string keyed in and the image data as it is handwritten can be input and displayed by the same processing. .

In this embodiment, the management information and the actual data are separately stored in the output information area 46, but a storage format of the continuous data of the actual data and the delimiter code may be used instead of the pointer format.

The handwritten data input on the handwriting board p is, like the key data input on the keyboard K, the actual data in the output information area 46 for each word-by-word division operation by the "space" key 34. A new pointer is set and stored in the data memory area 46b, and the stored pointer is stored in the management data area 46b.
Since it is stored and managed by a, if the "BS" key 32 is operated to instruct the deletion of data, even in the handwritten data stored as image data consisting of the set of the input coordinates, a series of word units can be used. Can be deleted as data.

As a break, the "space" key 34 may not be used, but a means for detecting that a certain time has elapsed since the pen was released may be provided, and a break may be made when it is detected that there is no input for a certain time.

The operation may be performed not only by deleting but also by moving or copying in word units. Further, in the state of handwriting input in which the handwriting input board P is displayed in the input area 14a of the touch panel 14, when the handwriting input position exceeds the scroll start line L and the pen separation is detected, the handwriting input up to that point causes Since the display range of the handwritten image data echo-displayed on the handwriting input board P is scrolled and displayed according to the predetermined scroll range stored in advance in the ROM 22, it is possible to easily input even continuous long handwritten data. You can

The scroll width and the scroll start position may be set by the user, and the scroll start position may be displayed in any other display form or may not be displayed. Furthermore, when the number of scrolls is limited, it is possible to notify by special display that scrolling is no longer possible.
