FIG. 2 is an explanatory diagram showing a storage state of dictionary data stored in the ROM 4. The dictionary data is
Index data 201 for search shown in FIG.
2 and the English-Japanese dictionary data 202 classified into levels 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 the spelling 201a of the found word and the address 201b of the dictionary data corresponding to the found word. Figure 2
The English-Japanese dictionary data 202 in (b) is the basic meaning data 20.
Each record is composed of 2a and detailed information 202b to be inserted at a predetermined position of the basic meaning data 202a. The detailed information 202b is a list in which the insertion position and the insertion data are alternately listed.

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

First, in step S301, an input of a search instruction including 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),
The spelling 201a of the found word that matches the spelling of the English word of the search instruction input in step S301 is determined,
Using the address 201b of the dictionary data of that record, the record in the English dictionary data 202 of FIG. 2B is determined, and the basic meaning data 202a is stored in the display buffer (described later) in the RAM 5 of FIG.

Next, in step S303, the CPU 2
Initializes a display start position (which will be described later) in the RAM 5 used for display control, and in the next step S304, the display buffer 7 stores the data in the display buffer according to the display start position.
To display. Next, in step S305, the CPU 2 determines whether the input is a scroll instruction. If the input is a scroll instruction, the process proceeds to step S306, and in step S306, the scroll direction instructed in step S305 is performed. After correcting the display start position according to the above, the process returns to step S304.

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

FIG. 4 shows step S30 of FIG. 3 described above.
FIG. 3 is a diagram for explaining a change in the display start position and the display buffer in the RAM 5 of FIG. 1 by the processing in step 3, step S306, and step S308, and a display range that changes according to the change.

The state of FIG. 3A is the state when the found word "run" is searched and the display process in step S304 of 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 displayed from the beginning of the display buffer 402, and the display buffer 402 has a 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.

In the state shown in FIG. 3B, a scroll-up instruction is input in the state shown in FIG.
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 in the data 202a according to the detailed information 202b. Further, in order to prevent the display range from being extremely changed due to the change in the display data, the character displayed in the first digit of the first line in the state of FIG. 7B is also in the first line in the state of FIG. The number of characters inserted before the display start position 401 as shown in the first digit of "2
5 ”is added to the display start position 401.

In the state of FIG. 3D, the scroll down instruction is input twice from the state of FIG. 3C, and the display start position is reduced by “16 × 2 = 32” in step S306 of FIG. It is in the state of being

The state shown in FIG. 6E is a result of further input of a scroll-down instruction from the state shown in FIG. In step S306 in FIG. 3, it is discovered that the character at the beginning of the data is included in the area displayed by scrolling down, and “16” is simply displayed as the display start position 4
Instead of subtracting from 01, the display start position 401 is adjusted so that the leading character is at the beginning of the display range. The same adjustment is performed when the character at the beginning of the line (the character immediately after the line feed) enters the display range by scrolling.

As described above, according to the electronic dictionary of this embodiment, even if the semantic data being displayed is switched to the more detailed semantic data, it is displayed in the first digit of the first line before switching. Since the characters that have been displayed are displayed at the same position even after the switching, there is an effect that it is less necessary to perform the scroll operation again after searching for the data of interest.
