DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a handwritten character font printing apparatus according to the first aspect of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the construction of an embodiment of a handwritten character font printing apparatus of the present invention.

The handwritten character font printer shown in FIG. 1 has a central processing unit (CPU) 11 which is a digitizing means, a document code buffer 12 which is a reading means, a normal print font storage area 13, and a handwritten character which is a storage means. The font storage area unit 14, the expansion buffer 15, the print buffer 16 as a print storage unit, and the printer 17 as a print unit connected to the print buffer 16.

Next, each of the above components will be described in detail.

The normal print font storage area section 13 is an area in which a dot pattern of a font created by a maker is stored in a raster format using a read-only memory (ROM), for example.

The handwritten character font storage area 14, which is a characteristic part of the present invention, converts the data input by the user by handwriting into, for example, stroke data to determine the width and height of each character. By a RAM area in a device equipped with means for normalizing to a value of a certain size that takes into consideration restrictions such as memory capacity and registering this in a rewritable memory (RAM), or with a device having the means described above. This is a memory area using the stored IC card memory.

The character code buffer 12 stores the content of the document to be printed in the form of JIS character code and various control codes.

When a print request for a user handwritten character font is made, the CPU 11 retrieves the stroke-recorded data from the handwritten character font storage area portion 14 according to the contents of the document code buffer 12 and takes it out. After rasterizing into a raster format similar to the above, it is set in the print buffer 16.

When the characters in one line are assembled by repeating the above process, the CPU 11 issues a print command to the printer 17. The CPU 11 repeats this process until there is no code data in the document code buffer 12.

If the stroke record data for the code specified in the document code buffer 12 is not in the handwritten character font storage area 14, the CPU 11 extracts the raster-type character font data from the normal character font storage area 13 and expands it. Directly without going through the buffer 15
Set in the print buffer 16.

FIG. 2 shows a handwritten character font storage area unit 1.
4 shows the data structure of No. 4.

As shown in FIG. 2, the data structure of the handwritten character font storage area 14 has a stroke index table 21 for searching stroke data for each character using the JIS character code as a key, and a stroke designated from the stroke index table 21. It is composed of data sections 22 and 23.

Each element of the stroke index table 21 has an index value indicating the head of the memory position of the stroke data portion of each character.

Further, in addition to the above, there is an index value indicating the beginning of the memory position of the stroke data part of each character, or an index value when the stroke data part is not yet present. Reference numeral 24 indicates the case where there is no stroke data portion of the corresponding JIS code, and reference numeral 25 indicates that the stroke data portion is 22. Stroke index table 21
By checking whether or not the value of the element is 0, it is possible to immediately determine whether or not there are stroke data sections 22 and 23 as shown in the figure.

The stroke data section 22 has a data structure as shown in FIG.

SbSize0 indicated by reference numeral 26 is S
The data amount of the first sub-stroke that constitutes one handwritten character below bSize0 is represented.

The sub-stroke corresponds to, for example, 41, 42, 43 forming the character "A" in FIG. SbS is assigned to the memory address of SbSize0 indicated by reference numeral 26.
By adding the value of size0, SbSize1 which is the head of the second substroke can be obtained.
Size1 to SbSize2, S indicated by reference numeral 31
bSize3 can be sequentially obtained. In this case, the value 0 is stored in SbSize3 indicated by reference numeral 31 to indicate that there is no subsequent substroke,
This triggers the end of the expansion process for one character.

Stroke data for one character is expanded by SbS
It consists of the expansion of an arbitrary number of substrokes divided by sizeX.

X0 (reference number 27) and Y0 (reference number 2) in the first sub-stroke of the stroke data section 22.
8) shows the coordinate value of the starting point of the sub-stroke, which corresponds to X0 and Y0 at 41 when the origin 44 is located at the upper left in FIG. 3, for example.

Δx1 (reference numeral 29) and Δy1 (reference numeral 30) are increment values of the X (horizontal direction) component and the Y (longitudinal direction) component from the immediately preceding point in the sub-stroke, and are actually obtained. The coordinate value of the second point to be power is X0 + Δx1
And Y0 + Δy1. Similarly, the coordinate values of the third point are X0 + Δx1 + Δx2 and Y0 + Δy1 + Δy2.
Can be sequentially obtained.

Next, referring to the flow chart of FIG.
The operation of the handwritten character font printer of FIG.
The processing will be mainly described.

When the print request is accepted, the process shown in the flowchart of FIG. 4 is started.

First, the print buffer 16 is cleared and the print position to be written to the print buffer 16 is reset, the document code position to be printed in the document code buffer 12 is set to N, and the total number of character codes to be printed in the document code buffer 12 is set to M.
(Step S1).

Normally, the print code position is the head of the document code buffer 12, so the document code position is 0.

Every time one character is processed, the document code position N is incremented by 1 in step S21, which will be described later, and it is determined whether or not there is no document code to be printed (step S2). 12
If there is no document code to be printed in the step S22
Proceed to.

It is checked whether or not the print buffer is empty (step S22), and if raster data to be printed remains, print processing such as output to the printer 17 is performed (step S23) and the process ends.

On the other hand, if there is a document code to be printed in step S2, the code at the next document code position is extracted (step S3), and it is checked whether the extracted code is a character code or a control code (step S3). S
4) In the case of the control code in step S4, the process for each control code is performed (step S20). On the other hand,
If it is a character code in step S4, it is determined whether or not the printing state at that time is handwritten character printing (step S5). If it is determined in step S5 that the printing state at that time is not handwritten character printing, it will be described later. The process proceeds to step S16, and if it is determined that the handwritten character is printed at step S5, the process proceeds to step S6. The control of the print state as to whether or not the handwritten character is printed is performed by, for example, defining a control code for changing the state and switching it by the control code processing of step S20.

When the process proceeds to step S16 in normal printing, the normal print font storage area section 13 is processed by the same method as the conventional method.
The raster data of the corresponding character is copied to the print position of the print buffer 16 as it is.

If handwritten characters are being printed, the stroke index table indicated by reference numeral 21 in FIG. 2 is searched to check whether the index value is 0 (step S6). In step S6, the index value is 0
In this case, since there is no stroke data section, the process proceeds to normal printing in step S16. On the other hand, if the index value is not 0 in the above step S6, there is a stroke data portion, so the process proceeds to step S7.

The start address of the stroke data portion (this is also the start address of the first substroke) is S
(Step S7), the sub-stroke end address is obtained and set to E (step S8). Here, (S ++) indicates that the address of S is incremented by one after the content of the address pointed to by S is taken out, and the content of S is SbSize indicated by reference numeral 26 in FIG.
0, that is, the amount of data of the sub-stroke, and E is the start address of the next sub-stroke. By comparing this E with S that is sequentially added, it is used to determine whether or not the substroke has ended in step S, which will be described later.
Twelve.

Subsequently, the starting point coordinates are calculated (step S
9) Next, the next coordinates of the starting point are calculated (step S1).
0). Using these two sets of coordinates, a straight line connecting the two points is raster-drawn in the expansion buffer (step S11). The two sets of coordinate data are not used as they are, but are used by multiplying by a fixed number in order to align them with the size of the normal print font. Since the stroke data in each handwritten character font is normalized and recorded in advance to the same size, it is not necessary to multiply different constants for each character.

Next, it is judged whether or not the sub-stroke is continuing (step S12), and the above step S12.
If the sub-stroke is continued, the process proceeds to step S15, which will be described later, and the coordinate value next to the starting point is used as the coordinate value of the starting point, and the next coordinate value is obtained again in step S10.

On the other hand, if the substroke is completed in step S12, it is continuously checked whether or not there is another substroke (step S13). If there is a substroke, the processing of the continued substroke is performed again. To do so, the process proceeds to step S8.

If there is no sub-stroke, raster data for one character is completed in the expansion buffer 15, so it is copied to the print buffer 16 (step S1).
4) The print position in the print buffer 16 is updated by the number of characters (step S17), and it is determined whether the print position in the print buffer 16 is within the margin (step S1).
8) If the print position of the print buffer is within the margin in step S18, since one line has not been completed yet, the document code is taken out to the document code buffer 12 again (step S21). However, if the margin is exceeded, the printing process of step S19 (this is the step S
The same as the processing of 23), one line of raster data is written to the printer 17.

With the above processing, it is possible to print handwritten characters. In addition, there are advantages of conventional information processing devices and document processing devices (easy to rewrite, etc., uniform character quality and easy to see) and advantages of handwriting each character with a pencil etc. Easy and friendly)
It is possible to have and.

FIG. 5 is a block diagram showing the configuration of an embodiment of a handwritten character font registration device according to the second invention of the present invention.

The handwritten character font registration device of FIG. 5 is a central processing unit (CPU) 51 which is a search means, a keyboard 52 for inputting commands and codes, and input means used for handwritten character input and command selection. Pen 5
3, a display device 54 as a character display means, a code information buffer 55 for storing information such as a character code and the presence or absence of handwritten character registration, a handwritten character data storage unit 56 for storing handwritten character data as a storage means, originally A normal character data storage unit 57 that stores the fonts, a character code, a character, a list display screen (window) that is a notification unit that displays whether or not handwritten characters are registered, and an area display for actually inputting handwriting. The list display screen / input screen control unit 58 is a display control unit that controls the display device 54 so as to display an input screen (window) that is a unit.

Next, referring to the flow chart of FIG.
The operation of the handwritten character font registration device in FIG. 5 will be described.

First, when a command is issued (step T1), a character list in which characters are arranged in code order is displayed (step T2). Here the letters are displayed from the very beginning of the code. Then, the code information buffer is searched for the characters displayed in the current list (step T3), and which character is already registered is checked. As a result, a mark indicating that the character is registered is registered. It is used as a guide to inform the user of the registration status by turning on the light (step T4). After performing the operations up to this point from the command issuance, the operation waits for a user (waits for an event) (step T5). If there is any action by the user, it is first determined whether the operation is key input (step T6). If the operation is key input,
The code entered is the code (JIS C as the code
When handling ODE, the input is JIS COD
Is it E, or if it is a ward code, is it a ward code? ) Is indicated (step T13), and if the input is not appropriate, the input is canceled and the state of waiting for an event is entered again (step T5).
On the other hand, if the code entered by the key input is an appropriate code, it is checked whether or not the characters of the entered code are in the list currently displayed (step T14), and if there is, the code is displayed. When it is determined that the user wants to input the handwritten character by handwriting, a handwriting input area (handwriting window) is displayed as shown in FIGS. 7 and 8 (step T8). If the character corresponding to the entered code is not in the currently displayed list, the contents of the list are displayed again in the list including the character corresponding to the code (step T15), and then , A window for handwriting is displayed (step T8).

When it is determined that the key input is not made in the determination at the step T6, it is checked whether or not the pen touch is performed in the character columns shown in FIGS. 7 and 9 (step T
7) If so, it is considered that the character for which handwritten character registration is desired has been selected by pen touch, and the handwriting window is displayed (step T8). If it is not the designation of the character column, it is judged whether it is the previous page button (area) (step T17) (see FIG. 7 and FIG. 9 for the previous page button), and if so, the list currently displayed is displayed. The contents are displayed again in the list of contents for the previous one sheet (step T16). If it is not the previous page button, it is further determined whether or not it is the next page button (step T18) (for the next page button, refer to FIG. 7 and FIG. 9). It is displayed again in the table of contents for one sheet. If it does not correspond to both the front and rear buttons, it is determined whether or not it is the end button (step T19), and if not (that is, the pen-touched place is a meaningless place), the event wait state is set. Return (step T5).

If the end button is instructed, the displayed list is erased (step T20) and the command ends (step T21).

If the character to be handwritten is selected and the handwriting window is displayed (step T8),
Next, the character to be actually registered is input into the handwritten character input area (see FIGS. 7 and 8) (step T9). The processing after the input is performed by pen-touching any one of the three buttons shown in FIGS. 7 and 8, and pen-touching other than three locations is invalid.

First, it is judged whether or not the button is a registration button (step T10). If so, the data is written in the data storage area corresponding to the character code, and the code information buffer registered flag is written (step T2).
2) Erase the handwriting window (step T2
3) Return to the state where only the list is displayed (step T
3).

If the pen-touched portion is not the registration button, it is determined whether the pen-touched portion is the cancel button (step T11), and if so, the display of the character input in the handwritten character input area is erased. Then, the handwriting input waiting state is entered (step T9). If it is not the cancel button, it is further determined whether or not it is the cancel button (step T12). If it is the cancel button, it is considered that the handwriting input is canceled and the handwriting input window is deleted (step T23), and the list is displayed. Return to the state where only is displayed. If it is not the release button, it is regarded as not a valid pen touch, and the input waiting state is set (step T3).

There is an external character registration function for registering a character created by oneself using a word processor, word processing software on a personal computer, etc., and then using that character. Explain the difference in function.

In the external character registration, when assigning a code to a character created by itself, an unused portion such as a code dedicated to an external character or a punctuation mark code is assigned. That is, if a character "bold" is newly created by the external character function, the code is not assigned to the original division code 3432 (division 34 point 32) of the character "bold". On the other hand, in the present invention, when the character "thick" is selected from the character list and the handwriting is performed by himself, the code corresponding to this character is the same as the original code of the character "thick".

[0056]
