And a "conversion" key 9 for starting a search operation for dictionary data corresponding to the input headword after the headword is input. The display unit 4 displays the input headword and a search result of dictionary data corresponding to the headword.

FIG. 2 is a block diagram showing a control circuit of the electronic dictionary 1 of FIG.

In FIG. 1, reference numeral 10 denotes a central processing unit (hereinafter, referred to as "CPU") for controlling the entire electronic dictionary 1. The CPU 10 includes a keyboard 3, a read only memory (hereinafter, referred to as "ROM") 11, A random access memory (hereinafter, referred to as “RAM”) 12 and a display drive unit 13 are connected. The ROM 11 stores a control program 11a and dictionary data 11b executed by the CPU 10 for controlling the operation of the entire electronic dictionary 1. The RAM 12 has a character string data storage area 12a in which character string data of a headword being displayed on the screen is stored, a work area 12b for various programs, and a temporary save area 12c. The display drive unit 13 controls the display screen of the display unit 4 based on the display control of the CPU 10. The display unit 4 is controlled by the display drive unit 13 to display characters on the screen.

FIG. 3 is a diagram showing an example of an electronic dictionary having an English-Japanese dictionary for inputting English words and translating them into Japanese, and showing a screen display state of the display unit 4 corresponding to each key operation. FIG. 5A shows a screen immediately after the power is turned on by pressing the “ON” key 6, and a cursor 14 for inputting characters is displayed on the screen. (B) is, for example, "inte
When the headword "lligence" is input by the above-mentioned alphabet key 5, the input character is echoed back on the screen as it is. Next, the conversion key 9 is changed from the state of (b). When pressed, the entry word “intel” is displayed as shown in the screen of FIG.
The search result of the dictionary data corresponding to "License" is displayed. The first line in the screen of (c) is an alphabetic character string of a headword, the second line is a phonetic symbol, and 3,4.
The line is Japanese translation information. Further, when the clear key 8 is depressed from the state (c), the screen returns to the same entry word input screen as the screen (a) described above as shown in (d).

Next, based on a control program stored in a control program memory 11a in the ROM 11, C
The control procedure executed by the PU 10 will be described with reference to the flowcharts of FIGS.

First, when the "ON" key 6 is depressed in FIG. 4, in step 401, power-on processing (wake-up processing) such as oscillation of a system clock and initial processing of each hardware is performed. .
Next, in step 402, initial processing of each work area is executed. Here, initial processing is not performed on data in the character string data storage area 12a of the RAM 12, and the current state is maintained. In the next step 403, whether or not character string data exists in the character string data storage area 12a of the RAM 12, that is, a state in which dictionary data search results are displayed on the screen when the power is turned off immediately before the power is turned on. Is determined, and if it is determined that character string data exists, the process proceeds to step 412 (a dictionary data search process) in FIG. 5 described below. If it is determined in step 403 that the character string data does not exist, the process proceeds to step 404, in which the display screen is cleared and the entry word input screen is displayed (the screen shown in FIG. 3A).

Next, the process shifts to a key input waiting process at step 405, and waits for input of a headword character string by the alphabet key 5 of the keyboard 3. Then, when the key is pressed, whether the key is the "conversion" key 9 (step 406), or whether the key is the "OFF" key 7 (step 40).
7) It is determined whether the key is the "clear" key 8 (step 408) or the alphabet key 5 (step 409). If a key other than these keys is pressed, the key input at step 405 is performed again. Return to the waiting process.

Here, for example, when the "OFF" key 7 or the "clear" key 8 is pressed, the process proceeds to step 420 (off processing: hold processing) and step 419 (clear processing) in FIG. Go forward respectively. If the alphabet key 5 is pressed in step 409, the character code of the pressed alphabet key 5 is added to the character input buffer by one character in step 414, and the character code is added to the character code in the next step 415. After performing a display process of displaying one corresponding letter of the alphabet on the display unit 4, the process returns to the step 405 to wait for a key input.

On the other hand, if the "conversion" key 9 is pressed in step 406, it is determined in step 410 whether character string data to be searched exists in the character input buffer. If it is determined that the character input buffer does not exist, the process returns to step 405 to wait for key input.
2 is block-copied to the character string data storage area 12a.

Thereafter, in step 412, the RAM
After performing dictionary data search processing based on the character string data in the character string data storage area 12a and reading information such as phonetic symbols and Japanese translation, the process proceeds to step 413.
“Screen of FIG. 3 (c)” for performing display processing on the display unit 4 for each information such as a headword and a search result. Thereafter, the process proceeds to step 416 in FIG. 5 to perform a key input waiting process. In the next step 417, it is determined whether or not the “clear” key 8 has been pressed. If it is determined that the "clear" key 8 has been pressed, the character input buffer is cleared in step 419 and the character string data storage area 12a of the RAM 12 is cleared, and then the display in step 404 in FIG. The process returns to the screen clearing process and the display process of the entry word input screen. Note that when it is determined in step 408 in FIG. 4 that the “clear” key 8 has been pressed,
Proceeding to step 419 in FIG. 5, the same processing is performed. If it is determined in step 417 in FIG. 5 that the “clear” key 8 has not been pressed, the flow advances to the next step 418 to determine whether the “OFF” key 7 has been pressed. You. When it is determined that the "OFF" key 7 has been pressed, predetermined power-off processing (halt processing), system clock stop processing, and the like are performed in step 420 in FIG. The control operation ends.

In step 407 of FIG.
If it is determined that the "F" key has been pressed, the process also proceeds to step 420 in FIG. 5, and the same processing is performed. However,
In the off process of step 420 based on the determination result of step 418 in FIG. 5, that is, the off process from the state where the search result of the headword and the dictionary data corresponding to the headword is displayed, the character string data stored in the RAM 12 is stored. The power is turned off in a state where the character string data of the headword currently being displayed on the display unit 4 exists in the area 12a. Therefore, when the “ON” key 6 is pressed again, as shown in FIG.
If the processing is started from step 401 of step S403, it is determined in step 403 that the character string data exists in the character string storage area 12a, and the processing automatically branches to step 412 to automatically store the character string data. Search and display processing are performed on the character string data in the area 12a. That is, the display returns to the screen display state immediately before the power is turned off.

On the other hand, in the OFF processing in step 420 in FIG. 5 based on the result of the determination in step 407 in FIG.
This is a state in which no character string data exists in the character string data storage area 12a of the AM 12, or a state after it has been cleared. Therefore, when the process is started from step 401 in FIG. 4 by pressing the “ON” key 6 again, it is determined in step 403 that the character string data does not exist in the character string data storage area 12a. Therefore, a normal headword input screen display process and the like (step 404 in FIG. 4) are performed.

In step 418 of FIG. 5, "O
If it is determined that the "FF" key 7 has not been pressed, the flow returns to step 416 to wait for key input.

In the above embodiment, the character string data storage area 12a for storing the character string of the headword displayed immediately before the power was turned off was provided, and the initial processing was performed when the power was turned on. After that, by automatically searching for the saved headword, even if the power is turned off by the auto power off function during the search operation, just turn on the power again, The search result of the dictionary data immediately before turning off is automatically displayed on the display unit 4. Therefore, there is no need to re-enter the headword, and a very smooth search operation without interruption can be performed.

Also, unlike a general resume function,
There is no need for an area in the VRAM for storing the display state of the display unit 4 and an area for storing the state of various work areas.

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

If the "clear" key 8 is pressed,
At 27, it is determined whether or not character string data exists in the character input buffer. If it is determined that it exists, the process proceeds to a clear process (step 729) described later. If it is determined that it does not exist, a clear process of the dictionary type data storage area 17a is performed in step 728, and then the process of FIG. Return to the dictionary selection menu screen of step 705.

If the alphabet key 5 is depressed in step 717, the character code of the alphabet key 5 depressed in step 725 is added to the character input buffer by one character. When converting to a character, the character code of the alphabet in the buffer is converted to a kana character code. Further, in step 726, only one letter of the alphabet or kana corresponding to the added character code is displayed on the display unit 4 on the screen.
Return to the state of waiting for key input.

If the conversion key 9 is pressed in step 714, it is determined in step 718 whether character string data to be searched exists in the character input buffer. If it is determined that it does not exist, the process returns to the key input waiting state in step 713. If it is determined that it does exist, in step 719, the contents of the character input buffer are block-copied to the character string data storage area 17b. Thereafter, in step 720, a search process of dictionary data is performed based on the character string data in the character string data storage area 17b, and the kana character string of the headword is
After reading the kanji information and the meaning information, etc., step 72

After the display process, the screen of FIG. 7D waits for a key input in step 722.

Next, in step 723, it is determined whether or not the "clear" key 8 has been pressed. If it is determined that the "clear" key 8 has been pressed, step 729 is performed.
After clearing the character input buffer and clearing the character string data storage area 17b, the process returns to the screen clearing and entry word input screen display processing of step 712 in FIG.

In step 723, "clear" is selected.
If it is determined that the key 8 has not been pressed, the next step 72
At 4, it is determined whether the "OFF" key 7 has been pressed.
If it is determined that the "OFF" key 7 has not been pressed, the process returns to step 722 to wait for a key input.

In step 724, "OFF" is set.
If it is determined that the key 7 has been pressed, step 73
The process proceeds to 0, a predetermined off process, a system clock stop process, etc. are performed, the power is turned off, and the present control operation is completed.

However, in the off process of step 730 based on the determination result of step 709 in FIG. 8, ie, the off process from the dictionary selection menu screen display state, the dictionary type data and the character string data in the dictionary type data storage area 17a The character string data in the storage area 17b has been cleared. For this reason, when the power is turned on again, FIG.
In step 703, it is determined that there is no stored data in the dictionary type data storage area 17a.
Displays the dictionary selection menu screen.

However, if the power is turned on again after the off process in step 730 based on the result of the determination in step 715 in FIG. 9, that is, the off process from the headword entry screen display, the process returns to step 703 in FIG. It is determined that data exists in the dictionary type data storage area 17a. Therefore, the process flow of steps 704, 711, and 712 is performed, and the dictionary type data immediately before the power is turned off is automatically selected, and the process proceeds to step 71 of FIG.
In 2, the display screen is cleared and the post-heading input screen is displayed.

In the off process of step 730 based on the determination result of step 724 in FIG. 9, that is, the off process from the state in which the search result of the headword and the dictionary data corresponding to the headword is displayed, the dictionary type data and The power is turned off in a state where the headword character string data is stored in the dictionary type data storage area 17a and the character string data storage area 17b. Accordingly, the processing is started from step 701 in FIG. 8 by pressing the “ON” key 6 again, and steps 701 to 704 and step 711 are executed. In this step 711, since it is determined that there is character string data in the character string data storage area 17b, the dictionary data search processing in step 720 in FIG. 5 and the display processing in step 721 are automatically executed. This returns to the screen display state immediately before the power was turned off.

It is to be noted that "OF" in step 709 of FIG.
If it is determined that the "F" key 7 has not been pressed, the flow returns to step 706 to wait for key input.

In an electronic dictionary having a plurality of dictionaries at the same time as in this embodiment, the storage area for dictionary type data is added to the storage area for the dictionary type data in addition to the conventional character string data storage area for headwords.
The same effect as that of the first embodiment described above can be obtained by providing on the AM 17 and simultaneously checking the dictionary type data and the character string data of the headword when the power is turned on.

(Third Embodiment) Next, a third embodiment of the present invention will be described with reference to FIG.

If it is determined that the dictionary type has not been stored, a process of displaying a menu screen for selecting a dictionary type is performed in step 806.

On the other hand, if it is determined in step 803 that character string data exists, it is determined in step 804 whether the character type of the data stored in the character string data storage area 17b is kana character data. It is determined whether the data is alphabetical character data. If the character data is alphabetic character data, the English-Japanese dictionary function process of step 811 is executed. On the other hand, in the case of kana character data, a national language dictionary function process is executed in step 805. It should be noted that the processing in step 805 corresponds to steps 711 to 730 in FIGS. 8 and 9 of the second embodiment described above.
Is the same as the processing of

In the present embodiment, when a plurality of dictionaries are English character headings and Japanese headings, a dedicated dictionary type data storage area is not provided, but is stored in the headword character string data storage area. Since the selected dictionary can be determined by checking whether the character type in the character string data is alphabetic or kana, there is an effect that a more memory-efficient system can be realized.

(Fourth Embodiment) Next, a fourth embodiment of the present invention will be described with reference to FIGS.

In the above-described first embodiment, a dedicated character string data storage area 12a is provided on the RAM 12, and the dictionary data is searched using the character string data therein. It is not limited. That is,
