FIG. 2 is an explanatory diagram showing the storage state of dictionary data stored in the ROM 4. The dictionary data is
Index data 201 for search shown in FIG.
And English-Japanese dictionary data 202 classified according to the level of detail of the data shown in FIG. 2B.
In the search index 201 of FIG. 2A, each record is composed of a spelling 201a of the entry word and an address 201b of the dictionary data corresponding to the entry after the entry. FIG.
The English-Japanese dictionary data 202 shown in FIG.
Each record is composed of 2a and detailed information 202b to be inserted at a predetermined position in the basic meaning data 202a. The detailed information 202b is obtained by alternately listing insertion positions and insertion data.

Next, the operation of the electronic dictionary 1 according to the present embodiment will be described with reference to the flowchart of FIG.

First, in step S301, a search instruction including a spelling of an English word to be searched and a search start instruction is received. Next, in step S302, the CPU 2 of FIG.
Scan the search index data 201 of (a),
In step S301, the spelling 201a of the headword that matches the spelling of the English word of the search instruction input is determined,
Using the dictionary data address 201b of the record, the record in the English dictionary data 202 in FIG. 2B is determined, and the basic meaning data 202a is stored in a display buffer (described later) in the RAM 5 in FIG.

Next, the process proceeds to step S303, where the CPU 2
Initializes a display start position (described later) in the RAM 5 used for display control, and in the next step S304, stores data in the display buffer according to the display start position in the display unit 7 of FIG.
To be displayed. Next, in step S305, the CPU 2 determines whether or not the input is a scroll instruction. If the input is a scroll instruction, the process proceeds to step S306. In step S306, the scroll direction specified in step S305 is used. After the display start position is corrected according to the above, the process returns to step S304.

On the other hand, if the input is not a scroll instruction in step S305, the process proceeds to step S307, and the CPU 2 determines whether the input is a display switching instruction. If the input is a display switching instruction, the process proceeds to step S308, and the CPU 2 proceeds to step S3.
The data in the display buffer is processed with reference to the detailed information 202b of the record of the dictionary data 202 determined in step 02, and the display start position is corrected according to the processing, and then the process returns to step S304. If the input is not a display switching instruction in step S307, the process returns to step S301.

FIG. 4 is a flowchart showing the operation of step S30 in FIG.
3 is a diagram for explaining changes in the display start position and the display buffer in the RAM 5 in FIG. 1 due to the processing in steps S306 and S308, and a display range that changes according to the changes.

The state shown in FIG. 3A is a state when the entry word "run" is searched and the display processing in step S304 in FIG. 3 is performed for the first time. The display start position 401 in this state has a value of “0” indicating that data is to be displayed from the beginning of the display buffer 402, and the display buffer 402 has the basic meaning data 2 of “run”.
02a (see FIG. 2) is stored as it is. The display range in this state is as shown in the figure because the number of displayable characters is 16 characters.

In the state shown in FIG. 3B, a scroll-up instruction is input in the state shown in FIG. 3A, and the scroll-up for one page is executed.
6, the display start position 401 is increased by the number of displayable characters “16”.

In the state of FIG. 3C, the display switching instruction is input in the state of FIG. 3B, and in order to display more detailed data, in step S308 of FIG. In this state, data is inserted into the data 202a according to the detailed information 202b. Also, in order to prevent the display range from changing extremely due to the change in the display data, the character displayed in the first digit of the first line in the state of FIG. , The number of characters “2” inserted in front of the display start position 401 so as to be displayed in the first digit of
"5" is added to the display start position 401.

In the state shown in FIG. 3D, an instruction to scroll down twice is input from the state shown in FIG. 3C, and the display start position is reduced by "16 × 2 = 32" in step S306 in FIG. It has been done.

The state shown in FIG. 3E is a result of further inputting a scroll-down instruction from the state shown in FIG. In step S306 in FIG. 3, it is found that the character displayed at the beginning of the data is included in the area displayed by scrolling down, and the display start position 4 is simply displayed as "16".
Instead of subtracting from 01, the display start position 401 is adjusted so that the first character is at the top of the display range. The same adjustment is performed when the character at the head of the line (the character immediately after the line feed) enters the display range by scrolling.

As described above, according to the electronic dictionary according to the present embodiment, even if the semantic data being displayed is switched to more detailed semantic data, the semantic data is displayed in the first digit of the first line before switching. The displayed character is displayed at the same position even after switching, so that there is an effect that after switching, it is less necessary to perform a scroll operation again in order to search for data of interest.

[Second Embodiment] Next, a second embodiment of the present invention will be described with reference to FIGS.

FIG. 5 is a block diagram showing the structure of an electronic dictionary which is an electronic device according to a second embodiment of the present invention. In FIG. 5, the same parts as those in FIG. The same reference numerals are given. In FIG.
