[Prior art]
2. Description of the Related Art Conventionally, an information display control device called an electronic dictionary that incorporates various types of dictionary databases such as a Japanese language dictionary, an English-Japanese dictionary, and a Japanese-English dictionary is known. The dictionary database stores a large number of dictionary data in which headwords are associated with explanation information for explaining and explaining the headwords. The user can display the explanation information corresponding to the headword that matches the input character by specifying the type of dictionary and inputting the input character.
[0003]
Some electronic dictionaries have various functions such as a jump function in order to efficiently search for information desired by the user. This jump function is to display the explanation information corresponding to the headword that matches the search word, and when the word in the explanation information is specified and a predetermined instruction is input, it matches the specified word. This is a function for searching again for a headword to be displayed and displaying explanatory information corresponding to the headword.
[0004]
When jumping between a plurality of dictionaries, a dictionary to be re-searched (that is, a jump destination dictionary) can be specified as follows. (A) A method in which a user designates a desired dictionary each time jumping is performed, or (b) a jump destination dictionary is set in advance and jumps to the same dictionary at all times (for example, see Patent Document 1) It is.

[0006]
[Problems to be solved by the invention]
However, the jump function described in Patent Document 1 has the following problems. That is, (a) In the method of selecting the jump destination dictionary each time, (1) the jump key is operated, (2) the displayed cursor is moved to the position of the character to be searched again in the explanation information, and (3) Operate the translation key, (4) Select the desired dictionary from the displayed list of jumpable dictionaries, and (5) Operate the translation key again. Jump to is executed. Therefore, each time you use the jump function, you need to specify the jump destination dictionary by performing this series of steps, so it is very annoying when you frequently use the jump function or jump to the same dictionary. Met.
[0007]
Furthermore, in this method, the user cannot know a jumpable dictionary until the character to be re-searched is determined and the translation key is operated. In other words, if the dictionary you want to jump to is not included in the list of jumpable dictionaries displayed after the character you want to search again is confirmed, or if you want to cancel the jump execution, for example, operate the return key It was necessary to cancel the confirmation of the character to be searched again, which was also inconvenient.
[0008]
In addition, (b) the method of presetting the jump destination dictionary is a convenient method for always jumping to the same dictionary. It was necessary to perform the procedure each time and specify the jump destination, which was also troublesome.
[0009]
In view of the above problems, an object of the present invention is to simplify an operation procedure in the jump function and to easily know a jumpable dictionary.
[0010]

The symbol “*” in the figure indicates that there is no data (no previous jump destination dictionary).
[0073]
[Operation]
Next, the operation will be described.
FIG. 13 and FIG. 14 are flowcharts for explaining the operation of the portable electronic dictionary 1 according to the dictionary search processing in the present embodiment. This dictionary search process is a process realized when the portable electronic dictionary 1 is turned on and the CPU 10 reads and executes the dictionary search program 54 in the ROM 40.
[0074]
According to FIG. 13, the CPU 10 first clears the jump history table 70 as an initial setting (step S11).
[0075]
When the type of dictionary is designated by the user (step S12), the CPU 10 causes the display unit 30 to display a character input screen for inputting the search word input characters for the designated dictionary. In this character input screen, the user operates the character key 5a to input an input character.
[0076]
When an input character is input, the CPU 10 searches the dictionary DB of the designated dictionary for candidate words that match the input character and displays a list. Then, the retrieval information corresponding to the headword (selected headword) selected by the user from among these is read from the dictionary DB of the designated dictionary, and the retrieval including the read explanation information and information including the selected headword is displayed. A result screen is displayed on the display unit 30 (step S13).
[0077]
Next, when the jump key 5d is operated on the search result screen (step S14: YES), the CPU 10 displays a cursor 150 for designating the search target character at the position of the first character of the selected entry word on the screen. (Step S15).
[0078]
Subsequently, the CPU 10 determines the character type of the character (search target character) pointed to by the cursor (step S16). Then, the jump destination candidate dictionary is determined with reference to the jump destination candidate dictionary table 51. Specifically, the dictionary associated with the character type of the search target character in the jump destination candidate dictionary table 51 is determined as the jump destination candidate dictionary (step S17).
[0079]
Thereafter, the CPU 10 refers to the jump history table 70 to determine whether or not there is a previous jump destination dictionary. Specifically, the presence / absence of the previous jump destination dictionary stored in association with the character type of the search target character in the jump history table 70 is determined (step S18).
[0080]
As a result, when it is determined that there is a previous jump destination dictionary (step S18: YES), the CPU 10 provisionally sets the previous jump destination dictionary corresponding to the character type of the search target character as the jump destination dictionary (step S19). ). On the other hand, if it is determined that there is no previous jump destination dictionary (step S18: NO), it is subsequently determined whether or not the search target character is a selected headword (step S20).
[0081]
As a result, when it is determined that the search target character is the selected headword (step S20: YES), the CPU 10 refers to the selected headword dictionary table 53 and determines a temporary setting jump destination dictionary. . Specifically, a recommended jump destination dictionary associated with the character type of the search target character in the selected headword dictionary table 53 is temporarily set as a jump destination dictionary. (Step S21)
[0082]
On the other hand, when it is determined that the search target character is not the selected headword (step S20: NO), the CPU 10 refers to the recommended jump destination dictionary table 52 and determines a temporary setting jump destination dictionary. Specifically, in the recommended jump destination dictionary table 52 corresponding to the designated dictionary, a recommended jump destination dictionary associated with the character type of the search target character is provisionally set as a jump destination dictionary (step S22).
[0083]
Thus, when the jump destination candidate dictionary and the temporary setting jump destination dictionary are determined, the CPU 10 displays the jump destination candidate dictionary list 170 based on the jump destination candidate dictionary and the temporary setting jump destination dictionary at a predetermined position on the search result screen. (Step S23). At this time, as described with reference to FIG. 2, the type of the jump destination candidate dictionary is displayed at a position corresponding to the arrangement position of the dictionary keys 6a to 6e, and the type of the temporarily set jump destination dictionary is shaded. indicate.
[0084]
When the cursor key 5b is operated on the search result screen displaying the jump destination candidate dictionary list 170 (step S24: YES), the CPU 10 changes the display position of the cursor 150 in accordance with the operation of the cursor key 5b. (Step S25), the process proceeds to step S16, and the same process is executed again.
[0085]
Further, when the enter key 5c is operated on the search result screen displaying the jump destination candidate dictionary list 170 (steps S24: NO to S26: YES), the CPU 10 selects the temporarily set jump destination dictionary as the search target character. Is stored in the jump history table 70 as the previous jump destination dictionary corresponding to the character type (step S27).
[0086]
Then, the search jumps to the temporary setting jump destination dictionary and executes a search using the search target character as a search word. That is, from the dictionary DB of the temporary setting jump destination dictionary, the candidate words matching the search target character are searched and displayed as a list, and the candidate word selected by the user from these candidate word candidates is displayed. Corresponding explanation information is read from the dictionary DB of the temporary setting jump destination dictionary and displayed together with the selected headword (step S28).
[0087]
When the dictionary key 6 is operated on the search result screen displaying the jump destination candidate dictionary list 170 (steps S26: NO to S29: YES), the CPU 10 is designated by the operation of the dictionary key 6. The dictionary is stored in the jump history table 70 as the previous jump destination dictionary corresponding to the character type of the search target character (step S30).
[0088]
Then, it jumps to the designated dictionary and executes a search using the search target character as a search word. That is, from the dictionary DB of the specified dictionary, search for candidate words that match the search target character and display a list, corresponding to the entry word selected by the user from among these candidate word words The explanation information to be read is read from the dictionary DB of the designated dictionary and displayed together with the selected headword (step S31).
[0089]
Thereafter, if the end of this process is not instructed (step S32: NO), the CPU 10 proceeds to step S12 and executes the same process. When the end of the process is instructed (step S32: YES), the dictionary search process is ended.
[0090]
Three operation examples in the portable electronic dictionary 1 configured as described above will be described below in order.
[0091]

The present invention can be applied to electronic devices such as watches and PDAs (Personal Digital Assistants).
[0143]
(2) Electronic dictionary system
In the above-described embodiment, the portable electronic dictionary 1 has been described as a so-called stand-alone device that operates alone. However, the apparatus to which the present invention is applicable is not limited to this. Specifically, the communication apparatus can be built-in or connectable, and the apparatus according to the present invention can be realized by communicating with a server. This will be specifically described with reference to the drawings.
[0144]
FIG. 21 is a diagram showing a schematic configuration of an electronic dictionary system in which an electronic dictionary terminal 1000 having a built-in communication device and a server 2000 are connected via a communication line N so as to communicate with each other. The server 2000 is composed of, for example, a general-purpose workstation or server computer, and the electronic dictionary terminal 1000 is composed of a mobile phone, a personal computer with a built-in communication device, a portable electronic dictionary with a built-in communication device, or the like. It is what is done. The communication line N is a wired / wireless telephone network or the Internet network.
[0145]
In FIG. 21, the function part which has the main functions of the portable electronic dictionary 1 in embodiment mentioned above was shown with the thick line. The dictionary search process executed by the CPU 10 of the portable electronic dictionary 1 is executed by the CPU 2010 of the server 2000. Data (various dictionary DBs, tables, etc.), programs (dictionary search program 54), etc. stored in the ROM 40 of the portable electronic dictionary 1 are stored in the storage unit 2060 of the server 2000 including a hard disk. Further, the RAM 2050 of the server 2000 stores data associated with the execution of the dictionary search process.
[0146]
On the other hand, the input unit 20 and the display unit 30 of the portable electronic dictionary 1 correspond to the input unit 1020 and the display unit 1030 of the electronic dictionary terminal 1000, respectively.
[0147]
That is, the server 2000 forms a host (or server), and the electronic dictionary terminal 1000 forms a host / terminal system (or server / client system) corresponding to a terminal (or client). Then, input characters and the like input from the input unit 1020 of the electronic dictionary terminal 1000 are transmitted to the server 2000 via the communication unit 1060, and the CPU 2010 of the server 2000 uses the dictionary according to various data and various programs stored in the storage unit 2060. The search process is executed, and the processing result is transmitted to the electronic dictionary terminal 1000 via the communication unit 2070 and displayed on the display unit 1030. As described above, the present invention can be realized by a system including the server 2000 and the electronic dictionary terminal 1000. In this case, the electronic dictionary terminal 1000 does not need to store data such as various dictionary DBs and tables, the dictionary search program 54, and the like, and does not need to execute dictionary search processing or the like. Therefore, the electronic dictionary terminal 1000 may be an electronic dictionary terminal 1000 such as a mobile phone having the CPU 10 having a relatively low arithmetic processing capability and the ROM 1040 having a relatively small storage capacity.
[0148]
【The invention's effect】
According to the present invention, in the execution of the jump function, in response to the search target character being specified, the type of set information corresponding to the specified character type is displayed as a jump destination candidate list, Corresponds to the character type The type of the aggregate report that is the jump destination in the previous execution of the jump function is identified and displayed from among the types of aggregate information displayed in the list and temporarily set. And The Enter key is operated In this case, the headword that matches the search target character and the explanation information corresponding to the headword can be read out from the temporarily set set information and displayed.
