Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character input device used as an input device for electronic dictionaries, electronic translators, electronic word learning machines, etc., and particularly for displaying multiple digit characters at the same time. a plurality of character input keys, each of which corresponds one-to-one to each digit of the plurality of digits; A means for inputting characters as input characters for digits, a display character forwarding key,
The present invention is characterized in that it is configured to include means for changing, based on the operation of the display character forwarding key, the displayed character of a digit other than the digit for which the corresponding character input key has already been operated to the next character. The present invention provides a character input device that does the following.

Hereinafter, the present invention will be explained in detail based on Examples.

FIG. 1 is a plan view showing the external appearance of an electronic English-Japanese dictionary with a computer function embodying the present invention.

In the figure, 1 is the power on key, 2 is the power off key, 3, 4, and 5 are character input keys, 6 is the return key,
7 is the forward key, 8 is the search key, 9 is the translation key,
10 is a display section.

Note that keys other than the above-mentioned keys are keys to be operated when using this electronic dictionary as a calculator.

FIG. 2 is a diagram showing key operations and displays based on the key operations when displaying a translation of the word "BACK" using the electronic English-Japanese dictionary shown in FIG. 1.

First, if you press the forward search key (▼), three characters of "A" will be displayed. Here, if the character input key 12 provided corresponding to the second digit is pressed, "A" is input as the second input character. next,
When the feed search key is pressed, the characters displayed in the first and third digits change to "B" while the second digit remains displayed. Here, if the character input key 11 provided corresponding to the first digit is pressed, "B" is input as the first character. Furthermore, if the send key is pressed, only the third digit displayed character changes to "C". Here, if you press the character input key 13 for the third character, the third character will be "C".
is input. “BAC” is set in this way. Then, by operating the search key (search) and translation key (translation), you can output the translation of "BACK".

FIG. 3 is a block diagram showing a schematic structure of the electronic English-Japanese dictionary shown in FIG. 1.

In the figure, 11 is a microprocessor, 12
1 is a key input device; 13 is a memory for storing dictionary information (read-only memory); 14 is a display control unit; 10 is a display unit; 15 is an address bus;
16 is a data bus.

The microprocessor 11 is a key input device 12
The operated key is determined by outputting the keystroke signal KS to the key input signal KI and reading the key input signal KI. It also specifies the address of the memory 13 and reads its contents. The display control unit 14 is a type of memory that stores whether each dot on the display unit 10 is lit or not lit, and the microprocessor 11 writes information corresponding to the display pattern to the display control unit 14. to perform the desired display.

FIG. 4 is a flowchart showing the control procedure of the microprocessor. However, only the parts related to the present invention are described.

In the figure, F ₁ is a flag indicating that the first character has already been set, F ₂ is a flag indicating that the second character has already been set,
F ₃ is a flag indicating that the third character has already been set, S ₁ is a character buffer that stores the character code of the character displayed in the first digit of the display, S ₂
is a character buffer that stores the character code of the character displayed in the second digit, _S3 is a character buffer that stores the character code of the character displayed in the third digit, and B is an input buffer.

The correspondence between characters and character codes is “A←→01,
B←→02, C←→03,…, X←→24, Y←→25, Z←→
26"
It's becoming like that.

After the power is turned on, flags F ₁ , F ₂ and F ₃ are reset, and character buffers S ₁ , S ₂ and S ₃ are cleared.

The operation will be described below, taking as an example the case where the translation of the word "BACK" is displayed.

When the forward key (▼) is pressed first, character buffers S ₁ , S ₂ , and S ₃ are counted up, and the content of each buffer becomes "01". Based on this, the display shown in FIG. 21 is performed. If the second character input key 12 is pressed in this state, the code "01" of the character "A" stored in _S2 is input to the second character B2 of input buffer B, and the flag _F2
is set. Next, if the feed key is pressed,
Only the letters S ₁ and S ₃ are counted up,
The content becomes "02". Based on this, Figure 2 3
The display shown in is displayed. If the first character input key 11 is pressed in this state, the code "02" of the character "B" stored in _S1 will be input to the input buffer B.
is input to the first character B1, and the flag _F1 is set. Furthermore, when the forward key is pressed, only the character buffer _S3 is counted up, and its content becomes "03". Based on this, the second
The display shown in FIG. 5 is performed. If the third character input key 13 is pressed in this state, the code "03" of the character "C" stored in _S3 is input to the third character B3 of input buffer B, and the flag is
_F3 is set.

If the search key (search) is pressed here, the first headword starting with the input character string "BAC" is searched, and the word "BACK" is displayed (FIG. 2, 7). From now on, each time the search key is pressed, headwords starting with "BAC" will be read and displayed in sequence, and after the last headword starting with "BAC" is displayed, the first headword above will be read again. The display returns to “BACK”. When the translation key (translation) is pressed, the translated words stored in association with the headword are read out and displayed (FIG. 2, 8).

In the above case, the search operation is performed by inputting three characters, but the number of input characters or the input character position can be set arbitrarily. For example, if you enter the first and third characters,
It is also possible to search for and display headwords whose first character is the same as the input character.

As explained above, according to the present invention, it is possible to obtain an extremely effective character input device for use in input devices such as electronic dictionaries.
