This completes the description of the configuration according to.

Next, the operation of the pen-type dictionary 1 will be described mainly with reference to FIGS. FIG. 5 shows a pen-type dictionary 1.
6 is a flowchart for explaining the main operation of FIG. 6, FIG. 6 is a flowchart for explaining the stroke reading process in FIG. 5 in detail, and FIG. 7 is a flowchart following FIG. 8 is an operation image diagram when the input key 6 is pressed, FIG. 9 is a diagram for explaining the constants A and B shown in FIG. 6, and FIG. 10 is a configuration diagram of the stroke buffer shown in FIG. is there. 11 is an operation image diagram when the conversion key 7 or the previous conversion key 9 is pressed, and FIG. 12 is an operation image diagram when the clear key 8 is pressed.

In these figures, first, when the user pushes the power switch 10, the control section 16 starts the control operation. The control unit 16 initializes hardware and variables (see S1 in FIG. 5). That is, the control unit 16 controls the variable h_
Set idx (the number of kana saved) to zero and set the variable c
Set onv_f (flag indicating that conversion is in progress) to zero.

Next, the control unit 16 enters a state of waiting for input of the keys 6, 7, 8 and 9 (see S2).

The control unit 16 determines whether or not the input key 6 has been pressed (see S3). If the user is pressing the input key 6, the control unit 16 affirms S3.

Next, the control unit 16 sets the variable conv_f to zero (see S4). Then, the control unit 16 determines whether or not the variable h_idx (the number of input kana) is a predetermined number or more (see S5).

If the number is equal to or larger than the predetermined number, the control unit 16 sets S
Return to just before 2. If it is less than the predetermined number (see S5), the control unit 16 calls the stroke data capturing function (see S6).

That is, as shown in FIG. 6, the control unit 16 clears the variable T (this is a variable for counting the time during which the pen tip 12 is away from the pressed body) according to the stroke data taking function. (T = 0, see S7).

Next, the control unit 16 sets the pointer 32 indicating the stroke data writing process at the head of the stroke buffer (see S8 in FIG. 6 and FIG. 10).

At this time, as shown in FIG. 8A, it is assumed that the user writes the pen tip 12 on the pressed body 32 by handwriting with a single stroke 33.

Thus, the processing function according to the control unit 16 is
The pressure sensor 13 is turned on, that is, the pen tip 12 is the pressed body 33.
Wait for the button to be pressed, and when it detects that it has been pressed,
The movement amount reading module 15 is instructed to start reading the movement amount (see S9).

At this time, the light from the light emitting portion 17 is emitted from the moving body 12
The light radiated to and reflected by is received by the light receiving unit 18. The movement amount reading module 15 processes the received image data with a DSP or the like, and starts conversion processing into a vertical movement amount and a horizontal movement amount. The processing function according to the control unit 16 is such that the movement amount reading module 15
The vertical movement amount and the horizontal movement amount (movement amount and direction) are acquired, and on / off information is acquired from the pressure sensor 13 (S
10).

Next, the control section 16 determines whether or not the pressure sensor 13 has output the ON information (see S11). Since the pen tip 12 has already been pressed, the control unit 16 affirms the determination in S11.

Then, the control unit 16 controls the variable T (moving body 1
The variable 2 for counting the time when 2 is away from the pressed body 33 is cleared (see S12).

Next, the control unit 16 calculates relative (X, Y) coordinate data based on the vertical and horizontal movement amounts (for example, the writing start position of one stroke is set to (0, 0)). (See S13). Then, the (X, Y) coordinates of that point are written in the stroke buffer from the position indicated by the pointer 32 (S1).
4 and FIG. 10).

Next, the control unit 16 returns immediately before S10,
The operations of S10 to S14 are repeated.

Next, it is assumed that the user pulls up the pen tip 12 from the pressed body 33 in order to write the next handwritten stroke 36, for example (see FIGS. 8A and 8B). .

At this time, the control section 16 negates S11. Then, the control unit 16 causes the pen tip 12 to press the pressed body 33.
The variable T for counting the time that is separated from is incremented (see S15).

Then, the control unit 16 determines whether the variable T is smaller than the first constant A (constant corresponding to the first predetermined time) (see S16). If the variable T is the first variable A
When it is smaller than, the control unit 16 affirms S16. At this time, the control unit 16 determines that chattering occurs, and S
Go back to just before 10.

Next, the control unit 16 determines that the variable T is the first variable A.
It is determined whether it is the above and is smaller than the second variable B (a constant corresponding to the second predetermined time, see FIG. 9) (see S17).

If the variable T is equal to or larger than the first variable A and smaller than the second variable B, the control section 16 affirms the determination in S17 and inputs one stroke (for example, as shown in FIG. 8A). It is determined that the handwriting input of one stroke 34) is completed.

Then, the control unit 16 controls the pointer 32 indicating the stroke data writing position in the stroke buffer.
(See FIG. 10) is advanced to the next position (see S18).
At this time, a plurality of (X, Y) coordinates indicating one stroke from the position of the first pointer 32 are stored as stroke data 35 in the stroke buffer. The stroke data 35 is
This corresponds to the handwritten one-stroke 33 (see FIG. 8A).

Next, the control section 16 repeats the operations of S10 to S14. As a result, the control unit 16 advances the pointer indicating the stroke data writing position in the stroke buffer to a further next position (see S18).

At this time, a plurality of (X, Y) coordinates indicating one stroke are stored in the stroke buffer as stroke data 37 from the second position of the pointer 32. The stroke data 37 corresponds to the handwritten stroke 36.

Next, the control unit 16 advances the pointer 32 to a further next position (see S18).

At this time, a plurality of (X, Y) coordinates indicating one stroke are stored in the stroke buffer as stroke data 38 from the third position related to the pointer 32. The stroke data 38 corresponds to one handwritten stroke 39.

In this way, the user writes the handwritten character “A” on the pressed body 33 with the pen tip 12,
It is assumed that the pen tip 12 is lifted for a while to write the next character.

At this time, the control unit 16 negates S11,
15 is executed, S16 is denied, and S17 is denied. The reason is that the variable T (variable for counting the time during which the pen tip 12 is separated from the pressed body 33) is the second variable B (second
This is because it is larger than the variable corresponding to the predetermined time) (see FIG. 9).

Next, the control section 16 stops the reading operation (see FIG. 19). That is, the control unit 16 issues an instruction to the movement amount reading module 15 to stop the movement amount reading, and returns to the program that called the stroke data reading processing function. At this time, a plurality of stroke data 35, 37, 38 indicating the handwritten character "A" are stored in the stroke buffer.

Then, as shown in FIG.
The stroke data is converted into hiragana (see S20). That is, the stroke data 40 (see FIG. 10) of one character sentence read in the stroke buffer is converted into hiragana by the stroke data analysis unit 28 according to the hiragana stroke data dictionary 29.

Next, the control section 16 determines whether or not there is a conversion error (see S21). If there is no conversion error, the control unit 16 negates S21.

Then, the control section 16 causes the buffer forming the storage section 22 to store the above-mentioned hiragana "a". The control unit 16 increments the variable h_idx (the number of saved kana) (see S22).

Next, the control unit 16 causes the display unit 4 to display the converted hiragana "a" through the display control program 24 (see S24 and FIG. 8D).

In this way, when the user inputs the handwritten character "A" on the pressed body 33, the pen-type dictionary 1 is the kana "A" converted from the handwritten character "A". Is input and stored. Then, the display unit 4
The converted kana "a" is displayed.

Further, when the user inputs "i" by handwritten characters on the pressed body 33, the control section 16 causes the control units S1, S2, S3, S4, S5, S6 shown in FIG. S2
0, S21, S22, S23 are performed.

At this time, the control section 16 increments the variable h_idx to be h_idx = 2. Then, the pen-type dictionary 1 has the handwritten character “i” (FIG. 8 (e)).
And (see FIG. 8 (f)), the kana “i” converted is input and stored. Then, the display unit 4 displays the converted kana "ai" (see FIG. 8G).

In this way, the pen tip 12 makes the pressed body 33
The locus moved while being pressed by (Fig. 8 (a), (b),
The handwritten character "ai" is obtained from (c), (e), and (f).

After the above operation, the control section 16 enters a key input waiting state (see S2 in FIG. 5). Then, the control unit 16
Determines whether the input key 6 has been pressed (see S3).

If the user wants to know the kanji corresponding to the hiragana "ai", it is assumed that the conversion key 7 is pressed. At this time, the control unit 16 negates S3 and affirms S24.

Next, the control section 16 determines whether or not the variable h_idx is zero (see S25). In the above example, the variable is 2, so the control unit 16 negates S25.

Then, the control section 16 determines whether or not the variable conv_f is 1 (see S26). In the above example, the variable is zero because we are not currently in conversion mode,
The control unit 16 negates S26.

Next, the control section 16 performs a kana-kanji conversion process (see S27). That is, the control unit 16 passes the converted kana-character string “ai” to the kana-kanji conversion engine 30 to perform the first kana-kanji conversion.

Then, the control section 16 controls the variable conv_f.
(Flag indicating the conversion mode is in progress) is set to 1 (see S28).

Next, the control unit 16 acquires the kanji character candidates that have undergone the kana-kanji conversion (see S29). The control unit 16 causes the display unit 4 to display the Chinese character candidate “meet, love, indigo” (see S30 and FIG. 11B), and enters a key input waiting state (see S2).

For example, the user may input "ai" by handwriting.
If the kanji that I am looking for is not found, it is assumed that the conversion key 7 is pressed again.

At this time, the control unit 16 negates S3 and sets S2
Affirm 4 and deny S25. At this time, since the conversion mode is already in progress, the control unit 16 affirms S26 and proceeds to B in FIG.

Next, the control unit 16 acquires the next Chinese character candidate (see S31). Then, the control unit 16 causes the display unit 4 to display the next Chinese character candidate “meet, encounter, accident” (S32 and refer to FIG. 11C) and enter a key input waiting state (FIG. 5). See S2).

If the user displays the above display (FIG. 11C).
If the kanji you are looking for is not found in (See), it is assumed that the previous conversion key 9 was pressed.

At this time, the control section 16 negates S3,
Negative to 24 and proceed to c shown in FIG. The control unit 16
An affirmative determination is made as to whether or not the previous conversion key 9 has been pressed (FIG. 7).
See S33).

In the above example, since the conversion mode is already in progress, the control section 16 makes an affirmative decision as to whether or not the variable conv_f is 1 (see S34). It should be noted that the control unit 16 uses S34.
When is denied, a key input waiting state is entered (see S2).

Next, the control unit 16 acquires the previous Kanji candidate (see S35). Then, the control unit 16 controls the display unit 4
On the other hand, the above-mentioned Kanji candidate "Meet, love, indigo" is displayed (see S36 and FIG. 11B), and the key input waiting state is set (see S2).

If the user mistakenly inputs "ai" in the handwritten character and inputs "ai,"
Displayed as 2 (a). Therefore, the user is "u"
It is assumed that the clear key 8 is pressed in order to erase.

At this time, the control section 16 negates S3,
Negative to 24 and proceed to c shown in FIG. Then, the control unit 16 negates S33 and affirms S37.

Then, the control section 16 controls the variable conv_f.
Is determined to be zero (see S38). In the above example,
Since the conversion mode is not currently in progress, the control unit 16 advances to S38.
Affirm

Then, the control section 16 determines whether or not the variable h_idx is larger than zero (see S39). In the above example, since h_idx = 3, the control unit 16 sets S
Affirm the judgment of 39.

Next, the control section 16 decrements the variable h_idx (see S40). Then, the control unit 16 causes the display unit 4 to erase the last one character “U” of the kana currently displayed (see S41 and FIG. 12B).
(See S2) and the key input waiting state is entered (see S2).

The control section 16 enters a key input waiting state when S37 is denied, when S38 is denied, and when S39 is denied (see S2).

As described above, the kana "ai" is converted into the kanji "meeting, love, indigo" etc., and the display unit 4 displays the kanji. That is, when the operation unit 5 is operated (for example, the conversion key 7 is pressed), the kana “ai” changes to the kanji “meeting,
It is converted to "Love, Ai" and displayed.
