Abstract

PURPOSE:To shorten the processing time and to reduce the burden to operation by switching display/non-display of the reretrieval function in accordance with the number of pertinent items. CONSTITUTION:The function for reretreval of pertinent items and a means which switches display/non-display of the function by judgement based on the number of retrieved pertinent items are provided. The reretrieval function is displayed when the number of pertinent items is large, but it is not displayed when the number of pertinent items is small. That is, when a retrieval word is inputted from a keyboard 15 and an objective item will be selected from pertinent items, a CPU 11 performs logical judgement or operation to determine whether the reretrieval function should be displayed or not by the number of pertinent items. When the reretrieval function is displayed, it is sufficient if a user executes reretrieval; but when it is not displayed, he finds that pertinent items are searched by scrolling more quickly than reretrieval.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic book searching apparatus for dictionaries, encyclopedias and the like, which uses a recording medium such as a compact disc in which data is stored.

[0002]

2. Description of the Related Art In a conventional electronic book search apparatus, a list of all relevant items is displayed after the search, and the user selects a desired item by using a scroll key, a previous page key, or a next page key. The item to be selected was selected.

[0003]

In the electronic book search apparatus described above, when there are a large number of corresponding items and the target item comes out many pages after the current display screen, the user can use the above-mentioned key. Had to press repeatedly.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention has a function for re-searching corresponding items and displaying / non-displaying a function based on the number of searched corresponding items. And a means for switching between.

[0005]

According to the present invention, the re-search function is displayed when the number of relevant items is large, and the re-search function is not displayed when the number of relevant items is small.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An electronic book search apparatus according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the arrangement of an electronic book search apparatus according to this embodiment. Where 11 is C
The PU makes a logical judgment or operation such as whether to display the re-search function according to the number of corresponding items shown in the flowchart of FIG. 12 is a main memory,
The storage area stores information necessary for controlling display / non-display of functions, and also stores image information of a display screen. A read-only memory (ROM) 13 has a program storage area in which a search program for electronic books such as a re-search program for the corresponding item according to the flowchart shown in FIG. 2 is stored. 1
Reference numeral 4 denotes a keyboard management unit, which acquires operator instructions and key input information input from the keyboard 15. A display memory 18 stores display data to be displayed on the display device 16. A display controller 17 displays the display data stored in the display memory 18 on the display device 16. 19
Is a CD mechanical unit including a motor for rotating a compact disc (CD) and the like, and 110 is a CD mechanical control unit that manages rotation control of the CD mechanical unit and reading of CD data. Reference numeral 111 is a data decoding unit for converting the CD data transferred from the CD mechanical unit 19 into data in a format that can be processed by the CPU 11. A bus 112 transfers data between the above devices.

The control procedure with the above configuration will be described with reference to the flowchart of FIG. When the search word is input from the keyboard 15 in step S21 and the target item is selected to display the text after the target item is searched in step S22, re-search is performed in step S23.
According to the number of applicable items, the number of applicable items is 1
If there are 24 lines or more in the display of 8 lines on the screen × 3 screens, the re-search function is displayed in step S24. If the number of relevant items is less than 24, the re-search function is not displayed in step S25. If the corresponding item of interest is not on the display screen in step s26 or is unlikely to be displayed on the next screen, for example, the English word "par" of "park"
I want to search for "k" but the spelling is "park" or "perk"
If the user does not know, in step S27, the user inputs "rk" in the backward matching search to perform the search. As a result, as shown in FIG. 3A, the corresponding item list screen displays the corresponding items sorted in the code order, and since there are 24 or more words, the re-search function is displayed. The user knows that the corresponding item of interest is a word starting with "p", and the word starting with "p" is sorted by word order.
Since it is unlikely to be displayed on the next screen, step S2
In FIG. 7, a prefix search is performed with “p” by the re-search function, and the target item can be displayed as shown in FIG. If the item of interest is in the display screen such as "dark" in FIG. 3A or on the next page of the display screen, the scroll key or the next page key which is the key in the keyboard 15 in step S28. You can find the desired item by scrolling the screen using. When the re-search function is not displayed in step S25, the corresponding item is searched only by scrolling in step S28.

[0009]

[Effect of the Invention] When the re-search function is displayed by switching the display / non-display of the re-search function according to the number of relevant items, the target relevant item is located farther forward or backward than the currently displayed item. At some point, you can let the user know that re-searching for the item is faster than moving it with the cursor, so the user only has to do the re-search, and if the re-search function is hidden, scroll it. It turns out that searching for an item is faster than searching again, and the user can reduce the processing time and the operation load on the user by searching for the corresponding item by scrolling.
