Abstract

PURPOSE:To easily attain the program searching of words by providing a means which detects the leading positions of the words positioned before and after displayed main sentence data, and moves the displayed result so that the detected words can be positioned at the head of a screen. CONSTITUTION:The heading part of the word is surrounded by a heading start code and a heading end code, and the descriptive text of the word follows it. When a previous item key 1 is pressed, the word item just previous to the top item of the items displayed at the present screen is searched by the start code, and the searched item is displayed again by using the left corner of the screen as a start point. When the next item key 2 is pressed, the word item just after the top item of the items displayed at present is displayed again in the same way. Thus, the words can be successively displayed at the head of the screen, and the list of the words of a dictionary can be easily recognized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a CD-ROM or ROM.
The present invention relates to an electronic dictionary device that searches for and displays a dictionary that is digitally stored in a storage medium such as a card.

[0002]

2. Description of the Related Art In recent years, compact and practical electronic dictionary devices have become widespread due to downsizing and cost reduction of microcomputers and memories, and market distribution of electronic dictionary software by CD-ROM.

An electronic dictionary device using a conventional CD-ROM will be described below. FIG. 7 shows a conventional electronic dictionary device, 3 is a screen previous page key, 4 is a next page key, 5 is a previous line key, 6 is a next line key, 7 is another input key, and 8 is a display device. The user can operate the 7 key group to display the result on the 8 display device and use the 3, 4, 5, 6 keys to scroll up and down. 3 scrolls up one screen and 4 scrolls down one screen. 5 functions as a one-line scroll up key, and 6 functions as a one-line scroll down key.

[0004]

However, in the above conventional device, only physical scrolling depending on the screen size is performed. That is, when the key 3 is pressed, the screen displayed at that time is scrolled up by one screen. Even if the number of lines for one screen is small, it operates in this way. Therefore, in the item where the description of one word is long, there is a problem that it is not possible to reach the items before and after unless scrolling is repeated many times. It was

An object of the present invention is to solve the above problems, and an object thereof is to provide an electronic dictionary having a good operability in which the heading position of each word can be recognized and the word can be easily located.

[0006]

In order to achieve the above object, the present invention detects the beginning of each word in body data and detects the beginning of words before and after the body data is displayed. It is provided with a means for moving the display result so that the detected word is at the beginning of the explanation.

[0007]

With the above arrangement, the present invention allows the words of the previous item and the next item to be displayed at the top of the screen by a simple operation.

[0008]

EXAMPLE An example of the present invention will be described below.

FIG. 1 is a perspective view of an electronic dictionary device according to an embodiment of the present invention, in which 1 is a previous item key, 2 is a next item key, and 3 to
8 is the same as the conventional example. 2 is a block diagram of the same,
9 is a CPU, 10 is a VRAM, 11 is a display unit, 12 is a RAM used as a work area by the CPU, 13 is a key input unit, and 14 is a ROM storing a program.
Is an instruction fetched from here. Reference numeral 15 is a memory in which dictionary data is expanded, which is referred to by the CPU.

The previous item key 1 and the next item key 2 in this embodiment will be described. FIG. 3 shows a state of a logical screen mapped to a physical screen. The logical screen has the same width as the physical screen and has the number of lines corresponding to the size of the dictionary. The physical screen can be thought of as scrolling up and down over the logical screen as the actual display window.
That is, the display window moves up and down by one line in the one-line scroll, and the number of lines in the physical screen by the page scroll. FIG. 4 shows the transition of the physical screen display when the previous item key 1 and the next item key 2 are pressed on the logical screen of FIG. When word 1 is displayed from the top of the screen and the previous item key is pressed from (a), the word x immediately preceding word 1 is cued to the top of the display on the screen.
From the state of (a), if the next item key is pressed, it moves to the word 2 (b), and if the next item is pressed further, it moves to the next word in sequence. Conversely, if you press the previous item key repeatedly (d)
From (c) to (c) and (c) to (a), it is possible to move to the previous item one after another.

Next, a method of realizing the operations of the previous item key 1 and the next item key 2 will be described with reference to FIGS. Figure 5
Shows the data structure of the dictionary text data recorded in the dictionary data memory 15, and the word heading portion in FIG. 3 is surrounded by the heading start code (e) and the heading end code (f) in this way. After that, the explanation of each word is followed. FIG. 6 is a program flow chart when the previous item key 1 and the next item key 2 are pressed. In the case of the previous item key, the item immediately preceding the item at the top of the word items displayed on the current screen is searched by the heading start code, and the found item is set as the start point in the upper left of the screen. Display again. In the case of the next item key, the item after the item at the top of the currently displayed word item is searched by the heading start code, and the found item is redisplayed with the upper left corner of the screen as the start point. To do.

As described above, according to the electronic dictionary device of the embodiment of the present invention, the cueing of an item can be quickly and easily performed by operating two keys.

[0013]

As is apparent from the above embodiments, according to the present invention, it is said that the electronic dictionary lacks the listability as compared with the dictionary of general books, but the head of items that are not books is said. Since it has the output function, words can be displayed one after another at the top of the screen, and it is possible to provide an electronic dictionary device with improved listability of what words are in the dictionary.
