Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention realizes a multi-window system by using a bit map display, and uses a personal computer or a workstation capable of handling Japanese data containing kana-kanji characters. The present invention relates to a word input device. [0002] In recent years, with the development of bitmap displays, a multi-window system in which a window is opened for each application program and a plurality of application programs are simultaneously operated on one physical display device has become widespread. [0003] Furthermore, regarding Japanese input, kana-kanji conversion input, in which a Japanese sentence to be input is divided into short words or phrases and reading and inputting and conversion operations are repeated, has been common. With the advancement of Kana-Kanji conversion algorithms, dictionaries, or Kana-Kanji conversion, Kana-Kanji conversion input has been realized, in which long sentence readings are input at a time and converted collectively. For this reason, when a Japanese input device is configured in a multi-window system, Japanese input to each window is required to be performed independently for each window. FIG. 6 is a conceptual diagram of a conventional Japanese input device in a conventional multi-window system, and FIG. 7 is an embodiment diagram of a conventional Japanese input device.
Is a diagram showing an example of character input in a conventional multi-window. As shown in FIG. 6, a Japanese input device in a conventional multi-window system has a kana-kanji conversion dictionary that stores kanji-mixed character strings corresponding to readings.
And a system that receives reading input from the keyboard input device 4 and extracts conversion candidates from the kana-kanji conversion dictionary 1 and displays the conversion candidates. Therefore, the Kana-Kanji conversion input device 2 performs Japanese input to a plurality of windows 3a and 3b by switching the notification destination of the Japanese input result simultaneously with switching of the window 3 for Japanese input. However, in this method, as shown in the block diagram of the embodiment according to the prior art shown in FIG. 7, an input reading buffer 6 for storing reading input from the keyboard input device 4 is provided.
0, since the kana-kanji conversion information storage unit 6 including the conversion information buffer 61 for storing the conversion start position and conversion state is common to the system, switch to another window 3b while inputting Japanese in one window 3a. Perform Japanese input,
Even if the window is switched back to the original window 3a, the conversion cannot be continued with the reading input in the original window 3a, and the conversion candidate is in a fixed state (that is, a state in which reconversion cannot be performed). . FIGS. 8 to 10 show examples of character input in a conventional multi-window system. In the figure, reference numeral 5 denotes a kana-kanji conversion dictionary 1 which receives a reading input from the keyboard input device 4 and stores the reading of the input and a conversion start position in the kana-kanji conversion information storage unit 6.
This is a kana-kanji conversion input processing unit that extracts and displays conversion candidates from. The following is an example of the character input operation in the multi-window system according to the prior art shown in FIGS. [0010] Japanese input is started in the window 3a. The input reading “Go Today” is displayed in window 3a and the input reading buffer 6
Stored in 0. A conversion operation of the input reading is performed, and the conversion result “Go to a doctor today” is displayed in the window 3a. Change the window for Japanese input to 3b. The result of the reading input in the window 3b, “makes it happy,” is stored in the input reading buffer 60. At this point, the window stored in the input read buffer 60
The reading entered in 3a “Go today” disappears. A conversion operation of the input reading is performed, and the conversion result “make the blade strong” is displayed in the window 3b. Change the window for Japanese input to 3a. Since the conversion result “Go to the doctor today” is not the intended result, we want to perform another conversion, but the input reading buffer 60 of the Kana-Kanji conversion information storage unit 6 stores the above window 3
The input result of the reading at b is stored in the input reading buffer 60, and the input reading at the window 3a entered above is entered in the input reading buffer.
Cannot be re-converted because it is not stored in. [0013] Therefore, in order to obtain another conversion candidate for the first input reading, the original reading “Kyohisa ni Iku ni Go” is input again and converted. There was a problem (fault) of fixing. In the conventional method of inputting and converting readings in units of short words as in the case of kana-kanji conversion input, it is easy to input another conversion candidate by re-inputting short readings. As described above, the method of inputting and converting long sentences at a time has a problem that a troublesome operation of re-inputting long sentences is necessary. In view of the above-mentioned conventional disadvantages, the present invention is a multi-window system, comprising: a kana-kanji conversion dictionary for storing kanji kanji character strings corresponding to readings; and a Japanese input means. In a Japanese input device that performs Japanese input independently for each window, during the conversion candidate display of Kana-Kanji conversion input, even if Japanese input is performed by switching to another window, switching to the original window, It is an object of the present invention to provide a Japanese input device capable of continuously performing a conversion operation in accordance with a reading already input in the window. FIG. 1 is a diagram illustrating the principle of the present invention. The above problem is solved by a Japanese input device configured as follows. A multi-window system, comprising: a kana-kanji conversion dictionary storing kanji kanji character strings corresponding to readings; and Japanese input means. Japanese Kana-Kanji conversion dictionary that is common to multiple windows and Kana-Kanji that stores input reading information and conversion information including conversion position and conversion status for each window where Japanese input is performed. When inputting Japanese into the window, receiving the input from the Japanese input means and storing the input reading information and conversion information in the kana-kanji conversion information storage corresponding to the window. Perform a kana-kanji conversion process using the kana-kanji conversion dictionary, and open a window for Japanese input from the window. The kana-kanji conversion input processing unit common to a plurality of windows, which performs a kana-kanji conversion process continuously based on the information of the stored kana-kanji conversion information storage unit when the window is further switched to that window. It is configured to be provided. FIG. 1 is a diagram illustrating the principle of the present invention. In the figure, 1

In the present invention, when Japanese input is started in the window 3a, the kana-kanji conversion input device 2a prepared in advance operates for the window 3a, and the reading from the keyboard input device 4 is performed. Input and conversion operations are received, conversion candidates corresponding to the reading are read from the Kana-Kanji conversion dictionary 1, the conversion result is notified, and Japanese is input to the window 3a. Similarly, when Japanese input is started in the window 3b, Japanese input is performed by the kana-kanji conversion input device 2b. Therefore, when Japanese input is performed in a plurality of windows, for example, the windows 3a and 3b, the separate kana-kanji conversion input devices 2a and 2b operate for each of the windows 3a and 3b.
If you switch to another window 3b while conversion candidates are displayed and Japanese is input, when you switch to the original window 3a, the readings you entered before switching will be the kana-kanji conversion provided for the above window 3a. Input reading buffer 60 in Kana-Kanji conversion information storage unit 6a in input device 2a
, The reading operation held in the input reading buffer 60 enables a continuous conversion operation. Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an explanatory view of the principle of the present invention, and FIG.
