Abstract

PURPOSE:To execute a re-input of a KANJI (Chinese character) inputted once, without executing a KANA (Japanese syllabary) to KANJI conversion and a selecting operation, by providing a KANJI re-input means for fetching a corresponding registered KANJI as an input KANJI from a KANJI history list. CONSTITUTION:A registration of a selected KANJI to a KANJI history list 19 is executed at the time point when a selection operating part 17 selects a KANJI in the end in accordance with an operator's instruction. In case a KANJI registered in the list 19 is re-inputted, a prescribed key provided on a KB11 is operated, and subsequently, a history number for indicating a re-input KANJI is inputted by a key. A KB input part 12 fetches a corresponding KANJI history from the list 19, stacks it in an input stack which is not shown in the figure, and the stacked KANJI history is delivered to a CRT output part 16 from the KB12, displayed on a prescribed position of a CRT monitor 15, and also delivered to a host device.

Description

[Detailed description of the invention]

[Technical Field of the Invention] The present invention relates to a Japanese input device having a conversion function for converting reading information of kanji inputted from an input means into kanji. [Technical Background of the Invention] Generally, when inputting kanji using this type of Japanese input device, the following steps are always required: (Romaji reading information for kanji →) Kana reading information for kanji → Kana-Kanji conversion → Homophone selection operation , is very troublesome. Conventionally, the efficiency of homophone selection operations has been improved by performing frequency management such that homophones to be selected are displayed in order of frequency of use. There is also a means for increasing the efficiency of subsequent homophone selection operations by, for example, registering the kanji selected by the homophone selection operation in a provisional dictionary. Furthermore, the process of converting kanji has been simplified by a new word registration means that registers frequently used kanji in a dictionary in correspondence with, for example, a short "yomi". [Problems with the background technology] However, these methods require Kana-Kanji conversion processing and homonym selection processing using dictionary lookups, and it is difficult to say that they greatly simplify the kanji input process. Ta. [Purpose of the Invention] This invention was made in view of the above circumstances, and its purpose is to provide a Japanese input device that can easily re-enter kanji that have been input without the need for kana-kanji conversion or selection operations. It is about providing. [Summary of the Invention] The present invention is provided with a kanji history storage unit that registers kanji input and determined through kana-kanji conversion and selection operations, with an identifier attached. The kanji characters registered in the kanji history storage section are displayed together with the corresponding identifiers by the kanji history display means. - Also, in the present invention, a first specifying means for specifying a kanji input from the kanji history storage section, and a second specifying means for directly or indirectly specifying an identifier corresponding to a registered kanji to be input in the kanji history storage section. is provided. When there is a designation by the first and second designation means, the corresponding registered kanji is retrieved from the kanji history storage section as an input kanji by the □ kanji re-input means based on the identifier designated by the second designation means. [Embodiment of the Invention] FIG. 1 shows the configuration of a Japanese input device according to an embodiment of the invention. In the figure, 11 is a key as an input means? 12 is a keyboard input section (hereinafter referred to as KB) for receiving data from the KBII.
(referred to as the B input section). KBII is a specific function key (hereinafter referred to as [PF1], not shown) that specifies the input of kanji (history) from the kanji history storage unit 19, which will be described later.
(referred to as a key). Reference numeral 13 denotes a kanji conversion unit that converts kanji reading information into kanji, and 14 a Japanese dictionary that is referred to in the kanji conversion process of the kanji conversion unit 13. 15 is a CRT-E monitor, and 16 is a CRT output unit for displaying input characters on the CRT monitor 15 and other kanji conversion results. 12
18 is a selection operation section which mainly performs homophone selection processing after kana-kanji conversion, and 18 is a provisional dictionary that is referred to when displaying selections. The temporary dictionary 18 is generated by the selection operation section 17. The provisional dictionary 18 stores the usage status of the past five selected kanji. Reference numeral 19 denotes a kanji history list (kanji history storage section) that stores the kanji (words or compound words) finally selected by the selection operation section 17. The kanji history list 19 is stored, for example, in main memory (or auxiliary memory). The kanji stored in the kanji history list 19 are referred to as kanji history. In this embodiment, the KB input section 12 has a kanji (history) input function using a kanji history list 19. The CRT output section 16 also has a kanji registration function for the kanji history list 19. FIG. 2 shows the structure of the kanji history list 19. In the same figure, Noru is the oldest used (Least -
Recently Used) Indicates the identifier of the kanji history, for example, the history number, and indicates the registered entry. mru is the most recently used (MostRe
c@ntly Used) indicates the history number of the kanji history, and m indicates its registered entry. Also, Cto
p indicates the current leading history number when displaying the kanji history on the screen, and C indicates its registered entry. Further, Hl (i=o to 9) indicates an entry related to the kanji history with history number 1. The content of this entry is the next most recently used kanji history in the history number amount.ft-(NextRecently Used)
It consists of a history number nru of the kanji history and a data pointer. This data pointer is a pointer indicating the data existing area of the kanji history with history number I. Note that if the Kanji history has a fixed length, it is possible to directly store data (Kanji history data) in the corresponding entry by using a pointer structure. By the way, in this embodiment, nru of the kanji history corresponding to mru is aO''.Next, the operation of one embodiment of this invention will be explained with reference to FIGS. 3 and 4. The figure is a flowchart showing how to register kanji (history) for kanji history number 19, and Fig. 4 is a flowchart showing the kanji (history) input procedure using kanji history list 19. First, kana-kanji conversion is required. We will explain the input of so-called non-kanji characters, such as alphabetic characters that are
It is passed to the CRT output section 16. Under the control of the CRT output section 16, the input characters from the KBII are displayed on the document display line of the CRT monitor 15, and are also passed to a host device (not shown). Next, Japanese input that requires kana-kanji conversion, so-called kanji input, will be explained. In this case, input characters such as ``6 Hiragana'' from KBll are passed to Kanji conversion section 13 and CRT output section 16 via KB input section 12. Then, under the control of CRT output section 16, input characters from KBll is displayed on a predetermined display line (second line of the system) on the CRT monitor 15. This is called Hiragana/Katakana echo. On the other hand, the Kanji converter 13 converts the input characters passed from the KB input unit 12 into ( Then, by repeating the above-mentioned input, the required length of readings (kana character strings) in units of words and phrases is stored in the kanji converter 13 (until an instruction to execute the conversion is given). For example, an instruction from the KBII to execute kana-kanji conversion is then transmitted to the kanji conversion unit 13 via the KB input unit 12.The kanji conversion unit 13 follows the instruction to execute the conversion and converts the Japanese Dictionary 1
4, convert the internally stacked kana reading information to the corresponding kanji (word, compound @) (while performing a grammar check if necessary). Some of these converted kanji cannot be uniquely determined due to the existence of homophones. The kanji conversion unit 13 passes the kana-kanji conversion result including the candidate kanji to the selection operation unit 17. When the selection operation unit 17 receives the conversion result from the kanji conversion unit 13, it edits it for selection processing that can be displayed on the CRT monitor 15, and outputs the conversion result to the CR via the CRT output unit 20.
It is displayed on the T monitor 15. The mode then becomes the selection mode, and the device waits for input (instruction) from the KBII in order to request selection processing from the operator. In this selection mode 9-, the path from KBII to KB input section 12 to selection operation section 17 is used, and the path from KB large input 12 to Kanji conversion section 13 is closed. In addition, KBII by operator operation
The selection processing instruction may be given directly to the selection operation section 17 without going through the KB input section 12. Also,
The selection process may be a batch selection process instead of a sequential selection process. Here, only the selection mode is important. Instructions from the operator include secondary candidates, previous candidates, and no conversion (
(Since there is no corresponding kanji, the hiragana reading is left alone), neither the kanji nor the hiragana to be canceled is selected), or the selection (select all the kanji displayed on the CRT monitor 15). Then, inputting instructions from the operator and displaying candidate kanji are repeated until the selection is finalized. When the selection is completed, the selected kanji is displayed at a predetermined position (document display line) on the CRT monitor 15 in the section 16j5 of the CRTItl input section 16. Also, this selected kanji is C
It is passed to the sihost 10 by the control of the RT river force 16. Furthermore, this selected kanji is C
It is registered in the kanji history list 19 under the control of the RT output unit 16. This registration operation will be described in detail below. The selected kanji is registered in the kanji history list 19 when the selection operation unit 12 finally selects the kanji (word or compound word) in response to an operator instruction. That is,
When the selection operation section 17 finishes selecting the kanji, it instructs the CRT output section 16 to register the selected kanji. This allows CRT
The output unit 16 performs the registration operation shown in FIG. 3 (it is also possible for the selection operation unit 17 to perform the interview registration operation).
The design of the CRT output section 16 was also old and used (t, R

). That is, the oldest used kanji history is purged from the kanji history list 19 within the CRT output section. This is based on entry tf in Kanji History 19.
This is done by incrementing the history number indicated by ru. Next, the CRT output unit 16 secures the entire area of the kanji history to be registered (step S, ?). That is, the CRT output unit 16 sets a data pointer to the area of the kanji history to be registered in the entry related to the kanji history with the history number indicated by tru. Next, the CRT output unit 16 registers the entire designated kanji history in the above-mentioned secured area and updates the LRU'l information (step SS). ff1lchi, entry tv
The nru registered in the entry related to the kanji history with the history number indicated by ua and tru is set, and the history number indicated by tru (the history number of the newly registered kanji history) is set in the entry m. . Further, nru, which was registered in the entry related to the kanji history of the history number indicated by mru before this setting, is updated to lru. Also, nru, which was registered in the entry related to the kanji history of the history number indicated by tru before the above setting, is updated to 0''.The unit of registration mentioned above is a word or a compound word.
