CONSTITUTION:A memory cartridge (ROM card) 4 is provided to the main body 2 of a portable electronic dictionary 1 via connectors 3a and 3b in an attachable/detachable way. The main body 2 contains a display part 5 and a keyboard part 8 including plural character keys 6 and function keys 7. Each key 6 has description of both KANA (Japanese syllabary) and alphabet at its key top for input of both Japanese and English words. The card 4 contains plural types of dictionary contents such as the Japanese-English, Japanese- German and English-German dictionaries, etc., and stores these dictionary information in each specific address. Thus a code conversion table is designated by a selection means in accordance with the information stored in the card 4. Therefore, it is not required to designate the types of characters.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to electronic devices such as portable electronic dictionaries with removable memory cartridges.

(b) Conventional technology In electronic dictionaries, it is possible to configure multiple types of dictionaries such as English-Japanese, Japanese-English, English-German, Japanese-German, etc. by replacing the memory cartridge, which is the dictionary ROM. Normally, a single character key is used for both the Japanese character input key and the English language input character key by writing both on the top of the key or near the key.

In such equipment, conventionally,
As disclosed in No. 619, when inputting English, the character key was pressed as is, and when inputting Japanese, the kana designation key was first pressed, and then the character key was pressed. For example, vanllm, EE] Dansei ■
and press the keys.

(8) Problems to be Solved by the Invention In the conventional technology, one character key can be used for inputting two types of languages, but when inputting Japanese, the character type is The user had to use the kana specification key to specify the ``kana'', which made key operations cumbersome.

(d) Means for Solving the Problems The present invention stores information indicating the type of input language in a removable memory cartridge, reads the information, and performs the following according to the read information: The above problem is solved by providing a selection means for selecting either a code conversion table for the first language or for the second language.

(*) Effect In the present invention, either the Japanese or English code conversion table is specified by the selection means according to the information in the memory cartridge, so that the input data can be changed not only when inputting English but also when inputting Japanese. All you have to do is press the character key that corresponds to the word, and there is no need to specify the character type.

(f) Embodiment FIG. 2 is a plan view of a Votaple electronic dictionary (1) as an embodiment of the present invention, and FIG. 1 is a block diagram showing its configuration. (3b) through the memory cartridge, specifically the ROM card (4

, multiple character keys (6) and function keys (7)
) and has a keyboard section <8), and in order to enable each character key to input both Japanese and English, one kana and "alphabet" are written on the key top.

Furthermore, in the block diagram, (9) is a CPU as a processing device, (10) is a timer circuit that generates an output at a predetermined period, and (11) is a program RO that stores a program.
M, (12) is RAM, (13) is display drive circuit, (1
4) is the internal dictionary ROM, which is an English-Japanese dictionary, and (15) is the internal dictionary ROM (14>) and ROM card (4). ) is selected, the memory selection switch outputs the detection signal SW of rH, and (16) is an English version memory selection switch that stores the correspondence between the key code output from the keyboard section (8) when a character key is pressed and the alphabet character code. The code conversion table (17) is a Japanese code conversion table that stores the correspondence between key codes and kana character codes, and (18) is a code conversion table for Japanese that stores the correspondence between key codes and kana character codes. A selection circuit (19) is an interface that selects the CP
U(9) has a configuration in which an interrupt is generated by a timer output.

By the way, the ROM card (4) has multiple types of dictionary contents such as Japanese-English, Japanese-German, English-German, English-French, etc., but as shown in Figure 3, it has a common format area (20) and its specific At address X, dictionary information indicating the type of input language is stored. Specifically, in 1 byte of address X, if the input language is Japanese, such as Japanese-English or Japanese-German,
Bit rl.

If the input language is English, such as English-Japanese, English-German, etc., the 7 bits are set to "1".
), it is possible to store only the dictionary contents or to store the dictionary contents and its search program together, so if a program exists, its start address is stored in the common format area (20
) is stored at a predetermined address X+1, and when there is no program, rO'' is stored at address X+1.

The processing contents of this embodiment will be explained below with reference to the flowcharts of FIGS. 4 and 5.

When the power is turned on and the memory selection switch (15) is switched, the main processing routine reads the detection signal SW and changes the switch state of the memory selection switch (15) after initialization, as shown in the flowchart of FIG. RAM(
12), and the switch state is stored in the internal dictionary ROM<
14), the selection signal SEL is set to "L" and the selection circuit (18) selects the English code conversion table (16).
). When the switch state is on the ROM card (4) side, one byte of dictionary information at address X of the inserted ROM card is read and its sixth and seventh bits are determined. When the 6th bit is "1", the selection signal SEL is set to "rH" to select the Japanese code conversion table (17), and when the 7th bit is "rl", the English code conversion table (16) is selected. ).

In other words, when the inserted ROM card is a Japanese-English, Japanese-German, etc. input language dictionary, the Japanese code conversion table (
17) is selected, and when the input language is an English dictionary such as English-Japanese or English-German, the English code conversion table (16) is selected.

Furthermore, the program information is read from the address A jump is made to a search routine for the program ROM (11), and if a program is found, a jump is made to a search routine for a ROM card (4). In these search routines, the input key code is converted into a character code by the selected code conversion table and displayed on the display section (5), and then the execution key (7a) is
When pressed, the contents of the dictionary specified by the switch (15) are searched, and the headword and bilingual translation corresponding to the input word are displayed on the display section (5).

Incidentally, the switching of the memory selection switch (15) is detected at the time of interruption by the timer output T. That is, when the CPU (9) is interrupted by the timer output, it reads the detection signal SW and outputs R as shown in FIG.
Compare with the switch status stored in AM (12),
If there is no change, a key scan is simply performed, but if there is a change, the program is programmed to return to step 2 of the mail processing routine in FIG. Therefore, each time the memory selection switch (15) is switched, the dictionary information in the ROM card (4) is read, and an appropriate code conversion table is automatically selected in accordance with this information.

Therefore, for example, a Japanese-English dictionary R can be used as a ROM card (4).
If you insert an OM card, press the memory selection switch (15
) when switched to the internal side, English can be entered by pressing the character keys, and when switched to the ROM card side, Japanese can be input simply by pressing the character keys.

In the embodiment described above, the memory selection switch (
15), the dictionary information of the ROM card (4) was read in response to switching of this switch (15).
In a device configured to always search the dictionary in the ROM card when the card (4) is inserted, a detection circuit (6) that detects the attachment or detachment of the ROM card (4), as shown in IA, is used.
21) and input the output of this detection circuit (21) instead of the memory selection switch (15), it becomes possible to read the dictionary information when inserting the ROM card (4). A corresponding code conversion table can be automatically set according to dictionary information.

(G) Effects of the Invention According to the present invention, information indicating the type of input language is stored in the memory cartridge, and a code conversion table is automatically selected according to this information. Even if it is used for two languages, there is no need to specify the character type, just operate the character key corresponding to the input word.
You can input your desired language and key operations are greatly simplified.
