Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic dictionary in which applications can be expanded by installing an IC card, and in particular information related to headwords in the main body can be expanded.

[Conventional technology]

Conventionally, when storing related information (opposite words, synonyms, meanings, etc.) on an extended IC card, the data structure on the card side usually has a heading section and a related information section as a pair. A method of searching for related information by looking at a match between part data, or a method of having address information as a position pointer on the IC card side in the main body in advance, etc., were used.

In addition, as a method for searching data on the IC card side, count the number of the heading that the desired data is from a certain point in the heading on the main body side, and search the data from the corresponding point on the IC card by that count number. A method has also been proposed in which related information in the IC card corresponding to the heading on the main body side is retrieved by sequentially forwarding the information.

[Problem that the invention is trying to solve] However,
When the IC card contains index information, it overlaps with the index data in the main body, which has the disadvantage of increasing the memory size of the IC card.Also,
If the IC card address information is stored in the main body in advance, the data structure on the IC card side will be limited, and card applications will be added one after another (in some cases,
The drawback was that there were restrictions on the card specifications.

In addition, in the method using the count number described above, the related information on the IC card side must completely match the heading information on the main body side in terms of arrangement and data number, and the data structure is limited to some extent. There was also a drawback that there were restrictions on expansion.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the electronic dictionary of the present invention includes a keyword storage means for storing keywords, and an index storage for storing addresses of reference locations of the keyword storage means. and for each keyword stored in the keyword storage means, either information related to each keyword or dummy data is stored in the same arrangement as the keyword stored in the keyword storage means. a related information storage unit for storing the address of a location corresponding to the reference location on the related information storage unit; a ranking storage unit for storing a rank for a word based on the reference location; and the related information The information stored on the storage unit is set to an address of an arbitrary location in the related information storage unit,
and a search means for searching according to the ranking from the relevant location.

[Effect]

According to the present invention, for each keyword stored in the keyword storage means, in the related information storage section of the external storage means,
If necessary, related information is stored, dummy data is stored for other items, the ranking of the desired keyword from the reference position in the keyword storage means is stored in the ranking storage means, and the related information storage is performed. The information stored in the section is searched according to the address of the location corresponding to the reference location stored in the index storage section and the ranking.

〔Example〕

Hereinafter, embodiments will be described with reference to the drawings, taking as an example an application that allows searching for semantic information for headwords using an IC card.

FIG. 1 shows the outside of the main body of an electronic dictionary which is an embodiment of the present invention. In the figure, 1 is an alphabet key, which is used to input a headword by inputting Roman characters. Reference numeral 2 denotes a display device, which displays the entered headword, kanji information as a search result, and meaning as related information. Reference numeral 3 is a conversion key, and by pressing this key after entering the headword, a search operation is performed and kanji information is displayed.

5 is a left search key, and by pressing this key, the searched headword can be searched in reverse order in the dictionary order.

6 is a right search key, which allows similar searches. Reference numeral 7 denotes an IC card insertion slot, and by inserting a dedicated IC card, an IC card application can be used on the main body side.

Next, FIG. 2 shows a schematic block diagram of the configuration of this embodiment. In the figure, 21 is a CPU that controls the entire device. 22 is a ROMI that stores a control program for processing the apparatus, heading information, and a dictionary that stores kanji information. In this ROMI, 22a is a control program memory that stores a control program, and 22b is a dictionary memory that stores a dictionary. Further, 23 is a ROM 2 on the IC card side connected to the main body, and includes a related information memory 23b for expansion of a card application control program memory 23a1 for controlling the card application.

24 is a work area 24a for various programs, ROMI
This RAM has an order information storage area 24b1 and a time save area 24c for temporarily storing order information of headings generated when searching the dictionary memory 22b.

25 is a keyboard section equipped with alphabet keys 1 and the like for inputting headings and performing various controls; 26 is a display drive section that controls the display screen of the display section 27, which will be described later, based on the display control of the CPU. .

Reference numeral 27 denotes a display section that displays characters according to the display drive of the display drive section 26.

Next, FIG. 3 shows the storage state of each data in the ROMI and ROM2. In the figure, reference numeral 31 denotes an index section on the main body side, which is divided into rows A to W, and is stored in pairs with address information corresponding to the data at the beginning of each row in the data section 32. 32a stores the data length of each data in the data section of the main body, 32b stores heading reading information, and 32c stores Kanji information in a coded manner. Reference numeral 33 denotes an index section on the IC card side, which has the same configuration as 31, and the address information is the start address of each row of the IC card side data section 34, which will be described later.

34a is the data length of each data in the IC card side data section, and 34b stores semantic data corresponding to the heading on the main body side. 34c is dummy data when there is no semantic data, and here the data length (=0)
are using.

Next, the operation of the present invention will be explained according to the flowchart shown in FIG. First, when a heading is input and a conversion operation is performed in step S1, in step S2, the main body index unit 31 determines in which part of the row to w row the first character of the input characters is included. demand. Next, in step S3, the start address of the data section is set from the index. Next, since this is the starting position of each block of the data section (divided by rows A to B), O, which is the initial value of the order information, is set in the order information storage area 24b (step S4). Next, in step S5, the reading data of the heading in the data section is compared with the input characters, and if they do not match in step S6, the data length is added, and the next heading address is updated ( At step S7), the order information is also counted up at the same time (step 38), and then comparison with the read data is performed in the same manner. Steps 85 to S8 are repeated for matching in step S6, and if the data match in step S6, kanji data corresponding to the heading is searched for and displayed in kanji in step S9.

If the related key is pressed in step 510, the start address of each block of related information (semantic data) is set from the index section of the IC card in step Sll using the same procedure as step S2 (step 512). The data of the address pointer set in step S13 is checked, and if it is not dummy data, then in step S17, the order information storage area 2
Check whether the count number stored in 4b has become 0, and if the counter has finished, step S19
The semantic data is displayed by If the counter has not finished counting in step S17, the pointer is advanced to the beginning position of the next data in step S18, and step 31
6, the counter value of the order information storage area 24b is set to 1.
is updated and the process returns to the data check in step S13.

If the data is dummy data (here 0) in step S13, it is checked in step S14 whether or not the counter has finished as in step S17. The address pointer is increased by one step, and the sequence information storage area 2 is moved up in step Sl.
The counter value of 4b is updated and the process returns to step S13.

Next, FIG. 5 shows the flow of searching for data stored in ROMI and ROM2. First, when "Shinrabanyo" is input as a heading, a character string is stored in the temporary save area 24c of the RAM 24. Next, if you search for the first character "shi°" using the index in the index section 31 on the main body side, you will get 3000, which is the first address of the data section, since it is a "sa" line.Next, look at the data at address pointer 3000. and "Resume (Saikai)", and when comparing the reading data "Saikai" and the input characters "Shinrabanjo", they do not match, so skip to the next heading "Disaster".This is repeated to find the first matching heading. “
The number of times 5 skipped until obtaining "Shinranbansho" is stored in the order information storage area 24b.Next, when the related key is pressed, the first address 2000 of the semantic data in the next row is read from the index section on the IC card side. is obtained. Therefore, if the headings are skipped five times according to the order information 5 stored earlier, the meaning data for "Shinranbansho" is obtained. At the time of the third skip, a dummy is created at the address 20180. Since data exists, instead of skipping data, the address is advanced by one point (to 20182) and the counter value is updated to 4.

[Other Examples]

In the above embodiment, an example was given in which semantic data is searched as related information, but the present invention is not limited to this. A system that performs translation operations between two languages using an IC card application is also conceivable. Figure 6 shows the storage state of data for English translation. 34a is the data length of each data in the data section on the IC card side;
4b stores English translation data corresponding to the headings on the main body side.

As a result, after obtaining the start address of the data with index 3, the data in the data section is skipped according to the order information, and the desired English translation is searched and displayed.

〔Effect of the invention〕

As explained above, according to the present invention, by using order information in the arrangement of headings in the main body, searching for related information in an IC card can be performed without increasing the memory of the IC card (and without increasing the memory capacity of the IC card). As long as the arrangement order of the data is the same as that of the main body, the data structure of the application is not limited (it can be freely configured), which is a great effect.
