Description

[Detailed description of the invention]

[Technical Field] The present invention relates to a character processing method that can perform display control to switch and display homophones one by one in a character string containing mixed kana and kanji characters based on an operation of a display instruction. [Prior Art] Conventionally, regarding this type of character processing device,
Various studies have been conducted, but when converting reading information into a character string containing mixed kana/kanji, there are often cases in which there are multiple homophones for the input reading information, and it is not possible to uniquely determine the reading information. Even if the desired homophone is uniquely determined, the user must then perform an operation to determine the desired homophone again. For this reason, it has been proposed to use a timer to switch and display homophones each time reading information is input, that is, only at the end of a sentence, and perform the above determination process (for example, Japanese Patent Publication No. 50-28299 ). However, in this case, the operator could not concentrate on inputting data, resulting in poor operability, and when considering the overall efficiency of the character processing method, there was still room for improvement. On the other hand, a method has been proposed that only displays a list of multiple candidates and allows the operator to select one desired candidate by simply inputting a numerical value, etc. (for example, 53-7131, JP-A-53-7132, etc.). However, it may be possible to display a list of homophones as a function of character processing, but as in the present application, based on the operation of display instructions, at a specified location in a character string containing mixed kana/kanji, This does not suggest a technique for controlling the display so that homophones can be switched and displayed one by one. In addition, various proposals have been made as prior art,
Although improvements have been made, there is nothing that suggests the features of the present invention related to character processing, and the technology of the present invention does not exist, even though there are various prior arts that are similar to the individual requirements of the present invention. Even if we consider all possible combinations of these, there is a problem that unless we are strongly aware of the problem that needs to be solved and desire it, it will never occur. [Purpose] In view of the above points, an object of the present invention is to control the display so that homophones are switched and displayed one by one in a character string containing mixed kana/kanji based on the operation of display instructions. The objective is to provide a character processing method. [Example] In the detailed description of the present invention described below, the predetermined number n is assumed to be two. In addition, the first character referred to in the present invention is hiragana,
It includes katakana, the Roman alphabet which is a combination of alphabetic characters, and other languages such as BOOK, and the second characters include the above-mentioned kana, homophone characters such as kanji corresponding to the Roman characters, and the above-mentioned.
It also includes synonymous characters such as "book,""book," and "book," which correspond to BOOK. An embodiment of the present invention will be described below with reference to the drawings. First, an outline of an embodiment according to the present invention will be described.
For example, when inputting the contents of a document as shown in FIG.
Notifies the device of the start of input. Next, the reading of the manuscript is input by operating, for example, a hiragana key. At that time, for the part of the reading input in hiragana that you want to convert into kanji and input, operate the kanji shift key at the beginning and end of the reading to inform the device of the part to be converted to kanji. Figure 2 is the first
This figure shows the key operation procedure for inputting the contents of the manuscript into the device, and the symbol “ ” indicates the operation of the kanji shift key. The contents of the manuscript inputted as described above are processed within the apparatus and displayed, for example, as a mixture of kanji and kana, as shown in FIG. In the above process, if there are multiple sets of kanji with the same sound, the kanji selected based on the frequency of appearance appears on the display. For example, when there are two sets of homophone kanji, the kanji with the second appearance frequency is “〔”“〕” as shown in Figure 3.
Displayed with. (Example: On the way home [project]) Furthermore, when there are three or more sets of homophone kanji, the homophone kanji with the third appearance frequency or later are represented, for example, by the symbol * as shown in the figure. If multiple homophone kanji exist for the reading of the input manuscript, the necessary kanji are selected by the following means. For example, the cursor symbol CC is moved to the "beyond" position in the "beyond" display in FIG. Such movement is performed by key operation. Since the kanji you want to select now is "transition", the NO key is operated to call up the kanji that is not displayed. Then, “hereafter” disappears from the display screen and “majesty” is displayed in the place after it, and the kanji for “intention” and * are displayed in “〔” “〕”.
A symbol is displayed. When the NO key is further operated, the display procedure described above is performed as shown in Table 1, and when the "transition" required for the time is outside of "[",
When the YES key is operated, “Migration” is selected and
The device moves the cursor symbol CC to the “return” of the next “return”
, and informs the operator of the next selection target position.

【table】

[Table] There is no * symbol for the next selection target, so selecting either one will complete the selection process. At this time, if you want to select "Intention" (here we select this based on the manuscript), simply select NO.
When the key is operated, the selection operation is completed and the cursor symbol CC moves to the next "year". If the same key operations as described above are performed, the selection is completed. Next, when the print key is operated, the entered text is printed out. Next, one embodiment of the present invention described above will be described in further detail. FIG. 4 is a block diagram of one embodiment of the present invention. In the same figure, KB1 is the first button on the keyboard.
The kana key HR is used to input the pronunciation of the text of the manuscript using kana input as shown in the figure, and the input kana information (hereinafter referred to as the first character string) is converted into kanji information (hereinafter referred to as the second character string). Kanji key KK to convert
and symbol keys such as interval keys SK. Such a keyboard KB includes an encoder for generating character codes corresponding to operation keys, and the character codes have a length of 14 bits. Note that the interval key SK and the kanji key KK may be the same key. At this time, it is distinguished by the number of key operations. KB2 is a keyboard with keys for requesting the device to execute various functions, namely, initialize key INTK, cursor key CK, print key PK,
It is equipped with YES key YESK, NO key NOK, cursor shift key CSK, etc. Initialize key INTK sets the initial state of the device. The cursor key CSK is a key for displaying a cursor symbol CC on the display surface of the display means. The print key PK is a key for printing the information of the first character string and the second character string stored in the device onto recording paper. YES key YESK converts the first character string into a second character string, and selects one of the second character strings when a plurality of them exist. NO key NOK is a key that converts a first character string into a second character string and displays the second character string that is not displayed when a plurality of second character strings exist. The cursor shift key CSK is a key for shifting the displayed cursor symbol CC one character at a time. Other functions of each of the keys mentioned above will be discussed in further detail below. Further, each key of the keyboard KB2 described above can request an interrupt to the processing section, and the processing section can determine which key has been operated. The CPU is a processing unit that performs, for example, 16-bit processing.
The processing unit CPU has functions such as data transfer, addition and comparison, and also processes interrupts.
For example, Texas Instruments
TMS9900, National Semiconductor's PACE,
It consists of Panahuacom's PFL16A, NEC μPD16, etc. ROM is control memory, keyboard KB1,
This is a read-only memory that stores control procedures, control data, etc. that determine input instructions from the KB2 and perform processing accordingly. IB is an input buffer that temporarily stores character codes input from keyboard KB1, for example.
It has a storage capacity of 9WORD (1WORD=16bit). PM is a page memory, which has a character capacity of, for example, 16 (characters) x 12 (lines) per manuscript page, as shown in Figure 6.
It has a capacity of 192WORD. Further, the contents of the page memory PM are displayed on a CRT (described later) and outputted to an output device such as a printer, a magnetic disk, etc. In addition, the 14th bit of each WORD of page memory PM,
The following information is stored in the 15th bit. When bit15=0 and bit14=0, the character code is entered in bit13 to bit0. bit15=0, bit14=1 The address of the homophone memory comes from bit7 to bit0. bit15=1, bit14=0 A cursor symbol is displayed along with the contents of bit13 to bit0. bit15=1, bit14=1 means love out code. WF is a word file, and as shown in Figure 7, the pronunciation of words (kanji) serves as a keyboard, and stores the character code of the word, the number of homophones, the number of translated characters, etc. for the pronunciation of the word. In this example, a storage capacity of 16WORED is prepared for one word, and the breakdown is 9WORD for the pronunciation (keyword) of the word, and 9WORD for the number of homophones.
1WORD, 1WORD for the number of characters of the word corresponding to the reading,
Consists of 5WORD allocation to word character code. Note that if there are a plurality of second character strings corresponding to one keyword, those words are arranged in descending order of frequency of use. For example, five types of words for "Iko" shown in FIG. 7 are stored in the word file WF, and in order to arrange them in order of frequency of use, they are arranged from the smallest address value to the largest address value. Therefore, the entered keyword is in the word file.
The reading of WF is compared with the processing unit CPU, and the corresponding character code is stored in the page memory PM. Note that when a plurality of words correspond to one keyword, the number of characters of the plurality of words are all configured to have the same length. for example,
Assuming that there are two words that correspond to "toshi", "year" and "city", the year is assumed to be year b. b means a blank code or a love-out code. DWM is a homophone memory, with a storage capacity of 256WORDs. This memory is an auxiliary memory used when converting the first character string to the second character string. When converting a first character string into a second character string, there are often multiple second character strings. In such a situation, the second character string that is used most frequently is displayed, and the second character string that is used the second time is displayed as “[”
It is displayed with "]", and if a third second character string exists, an * symbol is further displayed between "[" and "]". Therefore, as shown in Figure 8, the homophone memory DWM
Bit15 and bit14 store information with the following meanings. bit15=x, bit14=1 Indicates the end of one second character string group. bit15=1, bit14=1 This means that all sets of the second character string group have been completed. PNT is a pinta memory and has a storage capacity of 8 bits. This memory serves as an address register for specifying the position of the cursor symbol CC displayed on the display surface of the display means. DCOT is a display control circuit that has the function of displaying information such as the first character string and second character string stored in the page memory PM in a display format, and displays a cursor symbol at the position specified by the pointer PNT. It is something. Such a display control circuit DCOT has a character generator CG, and generates a pattern of the character by inputting a character code to the CG,
Displays the character code in page memory PM. In addition, the display control circuit DCOT is bit 15 of 1WORD.
The following control is performed using the information in bit 14. When bit15=1 and bit14=0, the character code stored in bit13-0 is displayed. When bit15=0, bit14=0 Same as above When bit15=0, bit14=1 Display * symbol. When bit15=1 and bit14=1, b is displayed (nothing appears on the display). The display control circuit DCOT controls the display to display 13 lines vertically and 16 characters horizontally. Therefore, if the page memory PM does not include a carriage return code or a line feed code, there is a counter in the display control circuit to count the number of characters to display 16 characters per line, and a counter to count the number of characters to display 16 characters per line. is equipped with a counter. In addition, when the processing unit CPU controls the page memory PM and pointer PNT, the display control control is
DCOT is performed during the transition from one line display to the next line display. A CRT is a display unit that consists of a cathode, a ray, and a tube. Such a display CRT is a display control circuit.
Display information under the control of DCOT. OU is an output device that prints the characters displayed on the display unit CRT. For example, it is composed of wire dots, ink jets, thermal printers, etc. Also, connect a magnetic disk etc. as an output device,
The storage capacity may also be increased. RAM is a memory that is provided to control the transfer of data processed by the processing unit CPU. For example, as shown in FIG. 9, there is a page memory register PMreg for storing character codes in the page memory PM, address data for reading, and addresses for writing to the homophone memory and reading data from the homophone memory. Homophone memory register to store data
DMreg, input buffer register IBreg that stores address data for writing to and reading from input buffer IB, and registers Jreg, Kreg, Lreg, Mreg, as temporary storage.
Nreg, Preg, Qreg, Rreg, Sreg and Dreg,
It has RR1 to RRN. AB, DB, and CB are address bus, data bus, and control bus, respectively. Figure 10 shows the operation of the embodiment constructed as described above.
This will be explained with reference to the control procedure shown in FIG.
Further, the contents of each step shown in FIGS. 10 to 18 are shown in Tables 2 to 10.

[Table] When power starts to be supplied to the device, the initial state of each part within the device is first set. The processing unit CPU uses the control procedure stored in the control memory ROM.
For example, input buffer register in memory RAM
IBreg, page memory register PMreg, homophone memory register DWMreg, etc., then write 0 to input buffer IB and write a blank code to page memory PM. The blank code is written in the page memory because the contents of this memory are displayed on the display CRT. A blank code also appears when the interval key SK is operated. Next, it is determined whether or not any key on the keyboard KB1 has been operated, and if no key has been operated, interrupt control is not performed, and it is determined whether each key on the next keyboard KB1 has been operated. keyboard mentioned above
If the keys KB1 and KB2 are not operated, the device continues in the above state until the keys are operated. Now, when the hiragana key is operated, step S5
The processing CPU determines whether it is a kanji shift key or not.
In this case, the answer is NO, so the character code corresponding to the input hiragana key is stored in the page memory register.
Paged memory directed by the contents of PMreg
Write to PM position. After that, increment the contents of page memory register PMreg by 1 and proceed to the next step.
In S8, the processing unit CPU determines whether the contents of the page memory register PMreg are 192 or more, and if it is not 192 or more, the process returns to key input control. If the text of the manuscript shown in FIG. 1 is to be input, the kanji shift key is first operated. step
In S5, the processing unit CPU detects that the kanji shift key has been pressed, and moves to key input control in step S10. When the hiragana key of the keyboard KB1 is operated in such input control, the character code of the operated hiragana key is stored in the storage location of the input buffer IB specified by the contents of the input buffer register IBreg, as shown in step S12. Input buffer register IBreg every time a character code is memorized
The content of is increased by +1. Therefore, after the kanji shift key is operated, the hiragana key changes to ``ko'', ``n'', ``ka'', and ``i''.
When operated, each character code is stored in the input buffer IB in order. When the kanji shift key is operated again after that, the process advances from step S11 to step S13, and the first character string of "konkai" stored in the input buffer IB is transferred to the word file WF.
The keywords are compared with the processing unit CPU. The contents of the word file WF are compared with the buffer IB, and if there is a match, they are sequentially stored in registers RR1 to RRN of the memory RAM. After the above comparison is completed, the processing unit CPU determines whether the number of homophones is one, and if it is one, the two character codes of "this time" of the second character string are written to the page memory PM, The process returns to step S3 for key input control. If the kanji shift key or hiragana key is operated to input the character "transition", the following control is performed. Since the number of homophones is not one in step S14, the process moves to step S16. In step S16, the processing unit CPU reads registers RR1-- of the memory RAM.
Among the homophone character codes written in the RRN, the characters after the first appearance frequency are first written into a predetermined position of the page memory PM (the position specified by the page memory register PM). When writing again,
The first memory location where the character code for “or” is stored.
"1" is stored in the 15th bit and "0" is stored in the 14th bit, and the contents of the page memory register PMreg are incremented by 1 each time one character code is stored. Next, it is determined whether the contents of the page memory PM have overflowed, and if not, control is performed in step S18. The processing unit CPU writes "[", that is, the left cutout, to the page memory PM. Next, the page memory register PMreg is incremented by 1 in order to move the writing position to the page memory PM. Next, the process moves to step S20, and the page memory register registers whether or not the page memory PM has overflowed.
Determine whether the contents of PMreg are 192 or higher. If the number is not 192 or more, the processing unit CPU performs control in step S21. In other words, the second frequency of appearance "majesty" is written to the page memory PM and the page memory register
Increase the contents of PMreg. Next, in step S22, the page memory register is reset again.
It is determined whether the content of PMreg is 192 or more, and if it is not 192 or more, the process moves to the next step S23. In step S23, it is determined whether the number of homophones is two. If there are two, write the right bracket "]" into the page memory PM as shown in step S24, and write the page memory register PMreg as shown in step S25.
Increase the content of the key input step S3 again
Return to If the number of homophones is not two in step S23, the process moves to step S26. “Majesty” at step S26
After the character, write "," to the page memory PM, and add 1 to the contents of the page memory register PMreg.
let Next, the contents of page memory register PMreg are 192
It is determined if the above is the case, and if YES, the process goes to step S9. If NO, write the contents of the homophone memory register DWMreg to the predetermined position of the page memory PM specified by the page memory register PMreg, and set “0” to the 15th bit and “1” to the 14th bit.
Write. The display control circuit DCOT displays, for example, * on the display CRT based on this information. After completing this write, page memory register
Increase the contents of PMreg and check whether the contents of page memory register PMreg have become 192 or higher.
If yes, go to step S9, if no,
Proceed to step S32. In step S32, the right corner, ie, "]" is written into the page memory PM.
When “]” is written to the page memory PM by the processing unit CPU, the processing unit CPU increments the contents of the page memory register PMreg by 1, then checks whether the contents of the page memory register PMreg is 192 or more, and
If YES, go to step S3; if NO, go to step S35, and store the remaining homophones in the homophone memory.
Write to DWM. Every time a character code is written to the homophone memory DWM, the homophone memory register
Increase the contents of DWMreg by +1. Therefore, each of the second character strings "intention", "transition", and "transition term" is stored in a predetermined position of the homophone memory DWM indicated by the homophone memory register DWMreg. At the time of such writing, "1" is written in the 15th bit of WORD and "1" is written in the 14th bit of WORD where the character code of the "transfer item" item is stored.
to remember. In addition, the 15th bit where the last character code of each homophone is stored is “0”, and the
Write “1” to 14 bits as shown in Figure 8. When the above writing is finished, step again.
Waiting for the next key input to control S3's key input. As mentioned above, the text of the manuscript shown in Figure 1 is
As shown in the figure, it is input into the page memory PM of the device using the kanji shift key and the hiragana key, and is displayed as shown in FIG. Next, when the cursor key is operated to check the reading converted from the first character string to the second character string that is not defined in the second character string, in the interrupt control of step S2, Determine which key was operated. At step IS5, it is determined that the cursor key has been operated, and the first
Cursor control is performed, details of which are shown in Figure 3. At step CS1, the processing unit CPU clears the contents of the page memory register PMreg. Next, read the page memory PM position determined by the contents of the page memory register PMreg, and read the 15th bit =
Check whether it is 1. If NO, step
Proceed to CS4, increment the contents of the page memory register PMreg by 1, and check whether the contents of the page memory register PMreg are 192 or more. In this case, the CPU has not reached the next location of the page memory PM.
Repeat the process of reading WORD and determining the state of the 15th bit until it appears. The above operation is repeated, and if the 15th bit = 1 when the 15th bit is 1, the processing unit CPU points to the contents of the page memory register PMreg. Transfer to memory PNT and step S3 shown in Fig. 10.
Performs key holding control. If step CS5 returns yes, the pointer memory is cleared and the process proceeds to wait for a key. The display control circuit DCOT displays a cursor symbol under "Following" in Figure 3 according to the contents of the pointer memory PNT.
Show CC. By configuring as described above, the cursor symbol is brought to the second character string where the second character string should be determined as one in the input sentence. The operator knows where to select by looking at the cursor symbol. The operator then operates the NO key because there is no word that is needed for the time being. When the NO key is operated, a step in interrupt control is activated.
The NO key is determined in IS8, and Figure 16, 1
The control shown in FIG. 7 is performed, and the key wait control is resumed. When the NO key is operated, the register Qreg is cleared by the processing unit CPU at step NS1, and the processing unit CPU clears the registers Kreg, Lreg, Mreg,
Set blank codes to Nreg and Preg. Next, in steps NS2 and NS3, the contents of the pointer memory PNT are transferred to the page memory register PMreg register.
Set to Jreg. Next, control is performed to check how many characters the second character string, which is not determined to be one, consists of. First, check whether the contents of page memory register PMreg are 191. Next, the contents of register Qreg are incremented by 1, and the contents of page memory register PMreg are incremented by 1.
Processing unit CPU has +1 page memory register
Read the character code determined by PMreg (in this case, “fall”) from page memory PM. Then, it is determined whether the read content is a left cutoff, that is, "[". The above control is repeated until "[" is found.
In this case, when the contents of the register Qreg become "2", "[" is found, and the process moves to the next control.
That is, the control is to save the two character strings in "[""]" in order to move the second character string in "[""]" out of "[". First, in step NS9, the contents of the page memory PM are increased by 1 to dress it as "power". Therefore, the processing unit CPU reads the contents of the page memory PM specified in the page memory register PMreg, and in the next step NS11, the processing unit CPU stores the read contents in the register Kreg. Next, in order to check whether the number of character codes to be saved has been reached, the processing unit CPU checks the contents of the register Qreg in step NS12. Since Q is not 1, after checking the contents of page memory register PMreg,
Increase the contents of page memory register PMreg by 1. Then, page memory is set in steps NS15 and NS16.
Transfer the contents of PM (light) to register L. As described above, the "prestige" in "[" and "]" is saved to the registers Kreg and Lreg. In the current example, the second character string consists of two character codes, but in this embodiment, it is possible to handle up to a second character string with five character codes, and by repeating the same control as described above, Register the character code Mreg,
Transfer to Nreg, Preg. At step NS17 in the case of “majesty”, Q=2yes and the control goes to step NS17.
Proceed to NS18. Page memory register after step NS18
Check the contents of PMreg and page memory register
The contents of PMreg are incremented by 1, and it is determined whether the contents of the page memory register PMreg are right-clicked, that is, "]". If there are two second character strings, then yes, in this case there are five second character strings that correspond to "Let's go", so step NS21 is NO.
Check the contents of the page memory register in step NS22, and the contents read in step NS20 are “,”
Check if it is. If it is not ",", an error is notified by means not shown. If it is ",", the contents of the page memory register PMreg are increased by 2. At step NS25, the processing unit CPU reads the contents of the page memory PM and stores it in the register Rreg. Also, set the 15th bit and 14th bit of register Rreg to 0. Homophone memory DWM with such steps NS25, NS26
This means that the address has been entered into register Rreg. Next, in step NS27, the page memory register is
Increase the contents of PMreg. Step NS21
If yes, step NS28 register Rreg
Enter 7FFF (hexadecimal display). Next, proceed to step NS29, in which the contents of the page memory register PMreg are registered.
Stored in Sreg. This data transfer is to save the contents of the page memory register. Next, in step NS30, the contents of register Jreg are transferred to page memory register PMreg. From this step, writing of the saved second character string to the page memory begins. First step NS31
Check whether the contents of register Rreg is 7FFF. If yes, step NS32 registers
The 15th and 14th bits of Kreg are set to 0. In this case, the answer is NO, so at step NS33, the 15th and 14th bits of register K are set to “1” and “0”, respectively.
is set to Next, the contents of the register Kreg are written into the page memory PM at the location where the character string "below" is located. Next, it is determined whether the register Qreg is 1 or not. Now, the contents of register Qreg is “[”, so in step NS36, page memory register
The contents of PMreg are increased by +1. Then register Lreg
The 15th and 14th bits of the register Lreg are set to 0, respectively, and the contents of the register Lreg are written to the page memory PM. Page memory register in next step NS39
Determine whether the contents of PMreg are larger than the contents of register Sreg. If yes, NO key control ends and the process advances to step S3, key wait control. In this case, the answer is NO, and the process advances to the next step NS40, where it is determined whether the contents of the register Qreg are "2".
Since the answer is yes, proceed to the next step NS41. if
If NO, it means that the character code of the second character string is stored in the registers Mreg, Nreg, and Preg, and the contents of the respective registers are written to the page memory using the control procedure described above. Step NS41 is to determine whether the contents of register R are 7FFF.If there are two second character strings when converting the first character string to the second character string, register R
is set to 7FFF as described above. Therefore, if register Rreg = 7FFF, the kanji in the bracket is the character that is needed for the time being, so the step
Perform the control shown after NS42 to end the NO key control. First, it is determined whether the contents of page memory register PMreg are larger than the contents of register Sreg. NO.
If so, the contents of the page memory register PMreg are incremented by 1, and the page memory PM loveout code 7FFF determined by the page memory register PMreg is written. The above-mentioned NS42, NS43, and NS44 are continued until the conditions of step NS42 are satisfied. By the above control, for example, when there are only two second character strings, ie, on the way home [project] is displayed, and when the NO key is operated to select a project, the display first becomes project [plan], and then the above-mentioned character string is displayed.
Planned by NS42~NS44
becomes. "" means blank display. If yes in step NS42, control is performed to move the cursor symbol CC to the next second character string that has not yet been defined as one character string. First, in step NS45, page memory register
Determine whether the contents of PMreg have reached 191.
If NO, the contents of the page memory register PMreg are incremented by 1, and then the contents of the page memory PM are read out. At step NS48, it is determined whether the 15th bit and 14th bit of the read content are "1" or "0", respectively. Steps NS45-NS48 mentioned above
is repeated, and when the condition of step NS47 is satisfied, the contents of page memory register PMreg are transferred to pointer memory PNT. display control circuit
The DCOT reads the contents of the pointer memory PNT and displays a cursor symbol CC at a predetermined position on the display CRT. When the above-mentioned control is completed, the processing by the NO key is completed. Returning to step NS41, if you select "Let's go" now, 7FFF is not set in register Rreg, so proceed to step NS51. Step NS51
Then, the page memory register PMreg is incremented by 1.
At step NS52, “[” is written to page memory PM. Next, proceed to step NS53, where the processing section
The CPU determines whether the contents of the page memory register PMreg are larger than the contents of the register Sreg, and if yes, the control by the NO key ends, and if no, the process proceeds to step NS54. In this step, the contents of the page memory register PMreg are incremented by 1.
Next, in step NS26, the contents of the homophone memory DWM correspond to the contents of the register Rreg to which the homophone address data was transferred, in this case, the “intention” of “intention”.
is read out, its 15th and 14th bits are set to 0, and a character code of "I" is written into the page memory PM indicated by the page memory register PMreg. Next, in step NS58, the page memory register is
Determine whether the contents of PMreg are greater than the contents of register Sreg, and if NO, homophone memory DWM
Contains the character code for “meaning” read from
Determine whether 1 is set in the 14th bit of WORD. If "1" is not set, the contents of register Rreg are incremented by 1, and steps NS54 to NS59 described above are repeated. When the last character code of one second character string is called from the homophone memory DWM, step NS59 is executed. Proceed to NS60. With step NS60
If yes, it means that the last second character string of the plurality of second character strings has been read out, and in this example of "Let's go", it is a "transition term". However, in this case, it is "toward", so proceed to step NS61.
At step NS61, the contents of register Rreg are incremented by 1. Next, the processing unit CPU
Write “1” and “0” to the 15th bit and the 14th bit, and increase the contents of the page memory register PMreg by 1.
From the contents of the page memory PMreg, "," is written to the page memory PM. next step
NS65 again determines whether the contents of page memory register PMreg are larger than register Sreg. If yes, perform the same processing as above. If NO, the contents of page memory register PMreg are incremented by 1,
At step NS67, the contents of register Rreg are written to page memory PM. In this example, the address of "migration" of "migration" is written. Next, the process advances to step NS68, where the processing unit CPU transfers the contents of page memory register PMreg to register Sreg.
If it is yes, it is processed in the same manner as in step NS65, and if it is no, it proceeds to step NS69. In this step, the contents of the page memory register PMreg are
1 and writes “]” to the page memory register PMreg. After the above control is completed, the contents of the page memory PM change from [Prestige, *] to Prestige [Intention, *]. Page memory register in next step NS71
The contents of PMreg are greater than register Sreg and NO
After completing the process using the key, the process waits for the key in step S3. When the above processing with the NO key is completed, the display will disappear from the display as described above, and the message will be "Prestige [intention, *]." The desired "transfer" has not yet appeared outside of "[". Therefore, when the NO key is pressed twice more, the contents of the page memory PM become "transition", and when the YES key, which will be described later, is operated, the selection of "Let's go" is completed. Here the above
The control when the NO key is pressed three times will be explained. When the "term" of the "transfer term" is read out from the homophone memory DWM, the result is yes in step NS60, and the process proceeds to step NS69. Since there is no second character string corresponding to "Ikou" in the homophone memory DWM, "]" is written in the position where "*" has been displayed up until now. Therefore, in order to write new data to the position where "]" has been written so far, the step
Controls NS71, NS72, and NS73 and writes love out code 7FFF to page memory PM. Such a love-out code does not appear on a display CRT in the same way as a blank code. When the above-mentioned control is completed, the process waits for a key at step S3. As described above, when the NO key is pressed and "transfer" is out of "[", when the YES key is pressed, the control shown in FIG. 15 is performed. First step S2
determines which interrupt key was pressed,
Proceed to steps IS6 and IS7. YES key is pressed,
When that key is determined, the contents of pointer memory PNT are transferred to the page memory register in step YS1.
Transferred to PMreg. This data transfer brings the contents of the page memory register PMreg to the "transfer" address. Next, to set the contents of page memory register PMreg to the address “[”,
Increase the contents of page memory register PMreg by 1,
Control is repeatedly performed to read the contents of the page memory PM and determine whether the contents are "[".
If yes in step YS5, the contents of page memory register PMreg are the address of "[", and steps YS6 to YS11 control to change unnecessary data from "[" to "]" to loveout code 7FFF.
It will be carried out in When such control is completed, the transition [transfer term] “ ”→transfer term “ ” “ ” “ ” “ ” “ ”
becomes. Next, in step YS12, it is determined whether the contents of the page memory register PMreg have become 191.
If NO, the contents of the page memory register PMreg are incremented by 1, the contents of the page memory PM are read, and the 15th bit of the read WORD is “1”.
Control steps YS12-YS15 to determine whether
is repeated to find the next position of the second character string that cannot be determined yet. In the display example shown in Figure 3, the same process is repeated until the address of "return" is found, and when it is found, the page memory register
The contents of PMreg are transferred to the pointer memory PNT, and the cursor symbol CC is displayed at the "return" position of "return". With the processing of the pointer memory PNT, all YES key processing is completed, and the process moves to key wait control in step S3. Note that if the answer is yes at steps YS2, YS7, and YS12, the pointer memory PNT is cleared and control proceeds to step S3. As described above, the print key is operated after the undefined second character string is determined to be one using the YES key and the NO key. The operation of the print key is determined at step IS5 of interrupt control, and the control shown in detail in FIG. 14 is performed. First, in step PS1, the contents of page memory register PMreg are cleared. then memory
Register Dreg in RAM is cleared. Next, in step PS3, it is determined whether the contents of the page memory register PMreg are 192 or not. Since it is now 0, read the contents of page memory PM in step PS4,
Increase the contents of page memory register PMreg by 1. Next, it is checked whether the read data is a love-out code, and if yes, steps PS3 to PS5 are repeated to read the contents of the next page memory.
In the case of a blank code, a blank is printed. If NO is returned in step PS6, the page memory
The contents of PM are sent to the output device OU via the processing unit CPU, and are printed, for example. In the next step PS8, the contents of register Dreg are +
Make it 1. It is determined in the next step PS9 whether the contents of the register Dreg has become “32” and NO
If so, return to step PS3 to retrieve the next print data. If step PS9 is yes, the carriage turn is
Output the line feed command to the output device OU.
The above control is continued until the contents of the page memory register PMreg reach 192, at which point the print key processing is completed and the process moves to key wait control in step S3. When the above key operations are completed, the page memory
In order to input the text of the next manuscript into the PM, the initialize key is operated to initialize the state of each part within the device. When such an initialize key is operated, it is determined in step IS1 of interrupt control in step S2, and control as shown in FIG. 12 is performed. First, the input buffer IB is cleared in step IS1. Page memory register at step IS2
PMreg is cleared. Pointer memory PNT is cleared at step IS3. In step IS4, the homophone memory register DWMreg is cleared, and in step IS5, the contents of the page memory PM are filled with a blank code. At this time, the number of each word is
The 15th bit and the 14th bit are 0. Note that it is better to clear the areas where writing and reading are performed to prevent malfunctions. When the above control is completed, the text input operation is performed again using the hiragana key and the kanji shift key as described above. In addition, in the above explanation, the cursor symbol CC was explained to be moved to the second character string, but
When the cursor shift key is operated, the following controls are performed. At step CS1, the contents of pointer memory PNT are
191, and if it is 191, the step
Clear the contents of pointer memory PNT with CS2,
The control is ended by moving the cursor symbol CC to the writing start position. If the answer is NO at step CS1, the pointer memory PNT is incremented by 1 and the process proceeds to step CS4. In such step CS4, the page memory register PMreg of the contents of pointer memory PNT is
The cursor shift control is terminated and the process proceeds to step S3, key wait control. In the above embodiment, one second
Although we have displayed a character string, it can be easily displayed as shown below. Examples From now on, [prestige, intention, *] Also, in the above example, "[""]" was displayed, but the display can also be suppressed. Example: From here on, majesty* You can also display only one character string. Examples:* You may also invert the display brightness and negative/positive. The second character string of the first occurrence is made different from the others. It is also possible to display "[""]" for the second character string with a high second appearance brightness, and to display only the first character string when the second appearance brightness is low. At this time, it may be possible to realize this by inputting the data of the appearance brightness into the word file and checking whether the ratio of the first brightness to the second brightness is a certain ratio. As described above, the character processing device according to the present invention has 1
After setting the second character that is not determined as one, the display symbol of the selection target is shifted to the display position of the second character that is not determined as one of the next selection targets, so the input text The work of calibrating can be done extremely easily. As is clear from the description of the embodiments, it goes without saying that the display control of the present invention can also be applied to cases where the display control of the present invention can be realized by supplying a program for performing the control to equipment or devices. [Effects] As described in detail above, according to the present invention, it is possible to control the display so that homophones are switched and displayed one by one in a character string containing mixed kana/kanji based on the operation of display instructions. It has become possible to provide a character processing method.
