Abstract

PURPOSE:To simplify the operation of a key, by starting the retrieval after detecting that characters of prescribed number are inputted, and then delivering the first headword starting at an input character or the input character train. CONSTITUTION:A microprocessor 12 delivers a key strobe signal KS to a key input device 13 and then read in a key input signal KI to discriminate the operated key. At the same time, the processor 12 designates the address of a memory 14 and reads in the contents of the memory. A display control part 15 serves as a memory that stores the lighting and non-lighting in accordance with each dot of a display part 7. The processor 12 performs a desired display by writing the information corresponding to a display pattern to the part 15.

Description

[Detailed Description of the Invention] The present invention applies to information retrieval devices such as electronic dictionaries and encyclopedias, and in particular, starts a search when it is detected that a preset number of characters have been input. This invention provides an information retrieval device characterized in that it outputs the first headword starting with an input character or an input character string.

Hereinafter, the present invention will be described in detail based on embodiments. FIG. 1 is a plan view showing the appearance of an electronic English-Japanese dictionary with a computer function, which is an embodiment of the present invention.

In the figure, l is the power on/clear key, 2 is the power off key, 3 is the return search key, 4 is the forward 9 search key, 5 is the character input key, 16 is the translation key, and 7 is the display of the first input character. ,! '['#-Crane is displayed.

Note that keys other than the above-mentioned keys are keys that are operated when this embodiment is used as a computer.

FIG. 2 is a diagram showing key operations and a display based on the key operations when outputting the translation of the word 'BOATI'.

First, when the feed search key 4 is operated, a dot indicating the above-mentioned 5-bit character is displayed below the character ``1 person'', and the specified character is 1AI, and the topmost character of the display section 7 is displayed. 1A' is displayed in the digit.Subsequently, by operating the feed search key 4, the display of the above dot moves below the character 1B#, and the display of the most significant digit also changes to 1B''. Here, by operating character input key 5, character 1B
N is input and the cursor is displayed at the second digit. .

Next, by operating the return search key 8, the display of the above dot returns to below the character 1A', and the second digit is Sa#dE.
If you operate the return search key 3 following the displayed 'of, the above dot display will move below the character 1Z" and the second digit display character will also change to i#. In this way, the return search key 8 Continue to operate, and the above dot will change to the character %0.
Move below 1 and when the second digit character display becomes ant o#, if you operate the character input key-5, the character %□l will be entered in the input area and the first input character string starting with 1B01 will be entered. A search for the Qi word is performed and the word ``BOARD'' is displayed.

Next, by operating the feed search key 4, the word 1BOAT next to 'BOARD' in alphabetical order is
' is displayed. If the translation key 6 is operated here, the translated word "boat, kopune" will be displayed.

FIG. 8 is a block diagram showing a schematic configuration.

In the figure, +2 is a microprocessor, 113 is a key input device, and 14 is a memo log port for storing dictionary information.
The processor 12 outputs a key strobe signal KS to the key manual input device +3, and determines the operated key by reading the key manual input signal Kl. It also specifies the address of the memory 14 and reads its contents. The display control section 15 is a type of memory that stores whether each dot on the display section 7 is turned on or off, and is a microprocessor.

Sir+2. The desired display is performed by writing information corresponding to the display pattern into the display control section 5. Note that 16 is an address bus, and 17 is a data bus.

FIG. 4 is a diagram showing two parts of the contents stored in the memory 14.

English words and their translation Q pairs are arranged in alphabetical order of English words.

FIG. 5 is a flowchart showing the control procedure of the microprocessor 12. However, only the parts related to the present invention are described.

In the figure, Fl is a flag indicating that the forward search key (-) or return search key (4) has already been operated, and F2 is a flag that indicates that the character entry key (IN) has been operated. The flag indicating F3 is the second character entry key.
A flag indicating that the operation has been performed and the polar search for the first word has already been completed, SC is the character number buffer, [SC]
HANO (The character corresponding to the character number a in consideration of Tsufa SC, B is the buffer 0. The correspondence between characters and character numbers is rA4->1.B Saki, C09, -:,,) (+24, Y++25,
Z4+ji! 5J 0 Below, we will explain the operation using an example where the translation of the word 'BOAT' is displayed. 0 After the power is turned on, flags Fl, F2, and F9 are reset.)
It will be displayed. Here, if you operate the feed search key, "1" is input to the character number buffer SC, and the flag Fl
is set. Based on the input of "1" to SC, the display shown in FIG. 2 (1) is performed.

If the feed search key is subsequently operated, since Fl is set this time, the SC is counted up.

If you operate the character input key here, flag F2 will be set and the character corresponding to the contents of SC, ie %BI
is input to buffer B: ``Do [Figure 2 (3)].

Next, if you operate the return search key, the S and C forces will count down and the content will become "1". Based on this, the second
The display shown in Figure (4) is displayed. If the user continues to operate the return search key, the contents of sc will become rQJ due to the countdown, so "26" will be input to the ESC. Based on this, by continuing to operate the return search key after 0, when the display shown in Figure 2 (5) is displayed, the SC will count down in sequence.When the content reaches "15", the display will change to The result is shown in Figure 2 (6).

Here, if you operate the character input key, the characters corresponding to the contents of SC, i.e. %□l, are input into I+ZFAB, and then the first Qi word starting with the input character string 'BO' is input. A search is performed and %BOARD' is read. After that, flag F3 is set.
) will be displayed.

Next, if you operate the feed search key, flag F3 is set this time, so the next word, ゝゝB
OAT'' is read out and the display shown in FIG. 2 (8) is performed.

Once the desired word has been read out, operate the translation key.
The corresponding stored translation word is read out and the flag F
After I* E2s F3 is reset, its display is performed. [Figure 2 (9)].

FIG. 6 shows that when it is detected that the forward search key (return) or return search key (4) has been suppressed for a predetermined period of time,
From then on, as long as the above key is pressed, the flowchart will be shown in which the specified character or headword is forwarded or returned at regular intervals. C is a counter, and Cm is a set value corresponding to the predetermined time.

As explained in detail above, the information retrieval device of the present invention includes:
The present invention is characterized in that when a preset number of characters are input, the first headword starting with the input character or input character string is output.According to the present invention, key operations are simplified. This has the effect of
