Abstract

PURPOSE:To decrease the frequency of key operation and improve the operability by extracting main text data which is being retrieved from dictionary information while referring to menu items of the lowest level when retrieval in menu form having hierarchical structure is performed. CONSTITUTION:A ROM 23 stores a control program and a retrieval program and a CPU 21 makes logical judgement and performs logical operations. When the retrieval in menu form having hierarchical structure is performed, address information of a menu of lower level below an item where a cursor is currently present is taken out with a lowest-order level key, and it is judged whether or not the next layer is a menu or a main text. When the next layer is the menu, menu data at the head of the level is taken out and tracing-back operation is performed one after another until the main text is reached; when the main text is reached, a menu item list screen of the lowest level is displayed on a display device 26. Then while the menu items of the lowest level are referred to, the main text data being retrieved are extracted from the electronic dictionary information.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention searches for data in an electronic dictionary using a compact disk as a dictionary medium and displays the contents of the text of the dictionary as a search result on a display device. It's about the player.

[0002]

2. Description of the Related Art Generally, in a dictionary format stored in a compact disc, as shown in FIG. 9, the contents of a document file 31 called an electronic book using a compact disc as a dictionary medium are the contents of the dictionary. In addition to the data 33, a document management block 32 that manages the entire document file 31, various indexes 34 for searching by keywords input by the user, menu data 35 for searching according to predetermined classification contents, and a plurality of searches. It is composed of a viewpoint management block 36 defining conditions and an external character font 37 for specific character data used in the literature.

In the conventional data retrieval apparatus for retrieving such an electronic book, any one of the indexes 34, the menu data 35, and the viewpoint management block 36 has a predetermined retrieval order, a retrieval word inputted by the user, and a selection. According to the above, the character data in the body data 33 that is uniquely determined is displayed on the display device.

In the conventional electronic book player as described above, when performing a menu type search having a hierarchical structure, the menu items at the lowest level are searched by following the hierarchical structure while selecting an appropriate menu item. Will be reached. FIG. 5 to FIG. 8 show the order and the situation in the case of performing a menu-type search using the electronic book of the Britannica subitem encyclopedia. That is, in FIG. 5, by pressing the key 41 again and then the literature key 42, the menu shown in FIG. 5 appears on the screen of the display device. Therefore, the cursor is set to one modern term and the enter key 16 is pressed. 6 becomes the screen shown in FIG. 6, and when the cursor is set to 1 Consider the global environment and the decision key 16 is pressed, the screen shown in FIG. 7 is displayed.
Here, similarly, one universe is selected and the decision key 16 is pressed to find one dark nebula in FIG. 8 and the decision key 16 is pressed to display the text of the dark nebula shown in FIG. 10 on the screen of the display device 26. Further, the display screen and each key shown in these drawings correspond to the display screen of the display device 26 and the keyboard 25.
Each of the above keys is represented.

By the way, at this time, the data about the lowest-level menu item finally reached is shown in FIG. 8, but the operator selects from among the menu items of each hierarchy,
A specific item is designated by using the cursor, and then the enter key 16 is pressed to obtain a menu item list of the next layer. Here, the above operation is repeated in the order of FIGS. 5 to 6 to 7 to select the first item in each menu hierarchy. In each layer, the display screen is switched, and if there is no target item, the previous page key 12 or the next page key 13 is used to switch the displayed screen to search for a screen displaying the target. When the operator wants to see the data related to other items, he or she wants to press the return key 15 to return to the upper layer and select the item again, or to see the cursor movement key if it is the same layer. Press and hold until the item data is displayed.

[0006]

Therefore, in the conventional electronic book player, when the user arrives at the menu item at the lowest level and looks at the item, if there is not the desired menu item, the above-mentioned items are obtained. The target item is searched for while returning to the upper hierarchy, but this task becomes complicated when the hierarchy level of the menu is deep or the number of menu items in the same hierarchy is large. In view of this point, the present invention has an object to provide an electronic book player having excellent operability.

[0007]

In order to solve the above problems, the present invention provides an English-Japanese dictionary in a compact disc,
A higher-level menu when performing a menu-type search with a hierarchical structure in a portable e-book player that searches and displays an electronic dictionary that stores dictionary information that is composed of text data of dictionaries represented by kanji dictionaries. Select the menu item of, and sequentially display the lowest level of all the lower levels connected to this selected higher level menu item, and search directly while referring to those lowest level menu items. It is an electronic book player capable of extracting electronic dictionary information from the body text data.

That is, the menu item at the lowest level can be referred to directly from the menu item at each level. Specifically, if modern terms are selected in FIG. 4,
It is an ebook player that sequentially displays all the lowest level menus connected to this selected modern term on the display screen and asks for the menu under search from them, which is the text from the lowest level menu item. This is because the contents of can be understood and the menu items that can be displayed are more than those displayed in the main text.

[0009]

With this configuration, even when the menu hierarchy is shallow, it is possible to check what kind of item there is at the destination of the menu, and the menu was traced many times to reach the bottom layer. It is possible to avoid a complicated operation such as searching again when the desired item is not found.
