The operation of this embodiment will be described with reference to the flowchart of FIG.

First, when the user selects the "Japanese dictionary" key 501 or the "ON" key (power-on key) 502 which is a mode setting key of the information input keys of the electronic information device body 1, the use mode of the Japanese dictionary is selected. Then, the processing of the application software for the Japanese dictionary is started (step S1). The pointer and the display mode are initialized (the initial state of the mode is the 16-dot display mode) (step S2), and FIG.
The initial screen of (a) appears (step S3). If any key is input in this state, the input key is read (step S4). Then, it is tested whether the "forward search" key 503 has been pressed (step S5).
If the entered key is not the "forward search" key, the process corresponding to each key is performed (step S7). When the entered key is the “forward search” key, the process of searching the top data of the dictionary is started, and the heading data 132 and the meaning data 133 indicated by the pointer 143 are read from the data section 131 in the ROM 13.
Are read into the buffer 144 (step S6). Next, the headline data is read into the first display buffer 111 (step S8). In the 16-dot display mode, the number of characters that can be displayed within the display range of the meaning data is read from the number-of-characters section 134 of the ROM to the register section 141 of the RAM, compared with the number of meaning data in the buffer, and it is determined whether the number is within the meaning display range. (Step S9) If the number of meaning data is smaller, it means that the meaning is within the display range. Therefore, the display mode is set to the initial 16-dot display mode. On the contrary, if the number of meaning data is larger, it means that the number of meaning data does not fit within the display range, so the 12-dot display mode is selected. In this example, the display mode is the 12-dot display mode, assuming that the display has not been suppressed (step S1).
0). Then, according to the display mode, the data for the number of digits that can be displayed from the address indicated by the meaning address pointer is set from the buffer 144 to the second display buffer 112 (step S11), and the process proceeds to step S12. In step S9, if the meaning data falls within the display range, the buffer 144 stores as much meaning data as the number of digits that can be displayed in 16 dots from the address indicated by the meaning address pointer.
To the second display buffer 112 (step S13). Since the corresponding data is set in the first and second display buffers 111 and 112 in step S11 or step S13, the first and second display areas 121,
Each display is expanded on 122 (step S12), LCD
It is displayed at 120. As shown in FIG. 6B, the headline data is displayed on the upper stage of the LCD, and the meaning data is displayed on the lower stage of the LCD, so that one screen is displayed. In this case 1
If it is in the 6-dot display mode, as shown in FIG. 6C, the screen will not fit on one screen (step S14).

Next, the display of the meaning data is switched from the 12-dot display to the 16-dot display. The input key is read (step S15). "12 dot switching"
It is tested whether a key has been input (step S16).
When the "12 dot switching" key is pressed, step S
Fly to 10. It is tested whether or not the "16 dot switch" key is pressed (step S17). If the "16 dot switch" key is not pressed, the process jumps to step S5. When the "16 dot switch" key 401 is pressed, the meaning data display mode is set to the 16 dot mode, and the process jumps to step S13 (step S18).

As described above, the display switching operation can be performed as described above, and it is possible to easily and effectively display the list.

The data retrieval is shown as an example of the head data retrieval process, but this method can be similarly used in the direct retrieval and the sequential retrieval.

Further, the display switching method for each character group has been described above, but the same method can be used for switching for each display area.

In the information display device of this embodiment, the display character type is switched (reduction or enlargement) for each group of display data.
Since it is possible to do, it is not necessary to reduce the data of the group that is stored in the screen to make it difficult to see, just by switching the character type only for the data of the group that protrudes outside the screen,
You can increase the amount of data that can be displayed within the screen range,
The list is improved and can be displayed efficiently.
On the other hand, if the display character type is small and difficult to see (without turning off the current application), you can switch the display within the same application to see it as an enlarged character type, and you do not need to start another application to view it. Excellent operability is also improved.
