Abstract

PURPOSE:To easily revise a display language of a message by revising an address table to be retrieved depending on the operation of an operator for switching display languages. CONSTITUTION:When the user depresses a language select key, a microprocessor 1 which detects the selection selects an address table to be retrieved for English from that for Japanese. When no language select key is depressed, the address table to be retrieved for Japanese is left selected. Then a data representing an address of an area in which an object message data is stored is retrieved and read depending on a kind of a message in response to the display content in the address table. Thus, the message is displayed on an LCD of a display section 4.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is applicable to copying machines, facsimile machines, vending machines, etc., when messages indicating operating procedures are displayed on a display such as a liquid crystal display (LCD). The present invention relates to a display device used.

[Conventional technology]

FIG. 8 shows a conventional example. Reference numeral 1 denotes a microprocessor that controls various parts of the microprocessor using a stored program method, 2 a ROM that stores programs for controlling the microprocessor 1 and message data for display, and 3 a RAM that is a stack memory for controlling the microprocessor 1. ,
4 is a display section for displaying the above message, and 5 is the next input/output port for sending control signals and data from the microprocessor 1 to the display section 4.

The microprocessor 1 reads data from the ROM 2 in accordance with the message to be displayed, and outputs it to the display section 5 via the input/output port 5. The display unit 4 displays a message on an LCD or the like according to the input mental data.

For example, when a user attempts to send a message using a facsimile IJ device, displays as shown in FIG. 9 are sequentially displayed.

[Problem to be solved by the invention]

With conventional devices such as those described above, even if a message is presented to a person, it is completely meaningless to someone who cannot understand the language, and especially if the message indicates operational precautions, the user may not be able to understand the content. There is also a high possibility that you will make an erroneous operation.

An object of the present invention is to provide a simple method that allows a user to select the language of a message to be displayed. a message table that stores message data according to display content for each language, an address table for each language that stores data indicating each message data storage address on the message table, a control section, and a display section,
The control section searches the address table for message storage address data corresponding to the display content, reads the message data stored in the corresponding address area on the message table and sends it to the display section, and also controls the operation of the controls. The address table used for the above search is changed accordingly.

[Effect]

Now, for example, if a device has a display function in English as well as standard Japanese, and the operator operates the language switch, the control unit detects this and first displays the language for the other language (English). The address table is accessed and data indicating the address of the area storing the message data of the corresponding content is searched. Then, access the area of the address on the message table. Since the desired message data in English is stored there, by reading it and sending it to the display section, the message display can be switched to English.

〔Example〕

An embodiment of the present invention will be described below when applied to a facsimile machine.

FIG. 1 is a block diagram showing the configuration of the device.

The same reference numerals as in FIG. 8 indicate the same or corresponding parts, but this embodiment is provided with a key manual unit 6 having a ninth key for switching the language of the displayed message, and the key operation is performed via the input/output board 5. and is input to the microprocessor 1. Friend, the ROM 2 is provided with an address table 21 as shown in FIG. 2(&) and a message table 22 as shown in FIG. 2(b).

This embodiment has a display function in English as well as Japanese, and the message data corresponding to the display of various contents in Japanese is stored in the ROM from address 201000 onwards.
From address 000000 onward, the next message data is stored corresponding to the same display using words. After address 100, data indicating the address where each message data is stored is stored. In this embodiment, the memory area of each address constituting the address table is further divided, and the upper bit side stores the Japanese message data storage address, and the lower bit side stores the English message data storage address. Of course, it is also possible to store message data storage addresses for each language at separate addresses. In this embodiment, when the Japanese address table is selected, from address 100 onward bi to J
-t bit address data is read out one after another, and when the English address table is selected, data at bit addresses below bj are read out.

Next, the operation will be explained using chart 70 in FIG.

The microprocessor 1 has a predetermined area of the ROM 2,
Loads data that determines the standard language displayed at power-on. In this embodiment, this is the Japanese language, and the Japanese table is selected as the address table (step 301).

Here, when the user presses the word # switching key, this is detected and the next microprocessor 1 (Stella 7' 302
), the address table to be searched is switched from the Japanese one to the English one (step 303). If the language switching key is not pressed, the address table for Japanese is selected and remains as it is.

Then, after being selected in this way, the message type (message No.) and the desired message are displayed on the address table according to the display contents (for example, the document should be placed in the pan, the recipient's telephone number should be entered, etc.). Search and read data indicating the address of the area where data is stored (
Step 3o4).

For example, if you want to display the message No. 1 in Japanese, use the address rloooJ, and if you want to display the message No. 3 in English, use r2040.
The address J and b are read. Therefore, next, the message data stored in the area of the above address on the message table is read and sent to the display section 4 (step 305).

In this way, a display as shown in FIG. 4 (tortoise) or Φ) is displayed on the LCD of the display unit 4, for example.

The case where Japanese is the standard has been described above, but of course English may be used as the standard. Mayu is not limited to Japanese and English, but may also be other languages, such as English and German, and the combination thereof is arbitrary. In addition to the standard language, it is also possible to provide an address table showing message data for two or more languages and their storage addresses, and to have a display function for three or more languages. In that case, it is possible to provide multiple language switching keys and switch to the language corresponding to the pressed friend key, but it is also possible to change the displayed language one by one by repeatedly pressing one key. .

In the above-described embodiment, the language is selected after the power is turned on, and
From then on, the display would be in that language, but not only immediately after the power was turned on, but at any time during subsequent operation.
It is also possible to change the display language each time a key is operated.

Next, an example will be explained using FIGS. 5 to 7.

In FIG. 5, the same reference numerals as those in FIG. Interrupts the processing operation of processor 1. That is, when the power is turned on, the microprocessor 1 reads the standard setting of the display language (corresponding to the initial value of the counter) from the selected language counter (described later) and selects the target language from the friend address table accordingly. The message data storage address data is read from the address area on the message table, and the message data is read from the corresponding address area on the message table and sent to the display section 4 (step 601).
~603).

On the other hand, when an interrupt occurs due to the pressing of the language switching key, the microprocessor 1 checks whether the built-in selected language counter can be counted up (step 701).
), and if it is possible to count up, the value is incremented by "1" (step 702). This counter indicates the currently selected language and its contents (
Count value) is an address table for each language that can be displayed and 1
It corresponds to 1:1. Therefore microprocessor 1
changes the used address table to an address table for the language corresponding to the count value after count-up (step 703), reads the target message data storage address data from the fi address table, and then changes the address table to the address table on the message table. Message data is read from the area and sent to the display section 4 (step 704).
, 705).

If the count value of the selected language counter exceeds the number of prepared address tables (number of languages) and cannot be counted up at the 57th time, reset the counter and change its contents to the default language. Return to the initial value (step 7o6). This allows you to switch the available languages in a ring.

In this manner, the user can easily select the desired language by repeatedly pressing the language switching key. Also, according to this method, when increasing the number of display languages, the ROMZ
This can be easily resolved by simply adding more tables.

In the nine embodiments described above, the selected language counter is built into one microprocessor 1, but it may also be provided using a predetermined area of the RAM 3. Further, although the count value is incremented each time the language switching key is pressed, it goes without saying that the count value may be counted down.

〔Effect of the invention〕

As described above, according to the present invention, the control section searches the address table for data indicating the next message data storage address corresponding to the display content, reads the message data from the area of the address on the message table, and displays the message data on the display screen. The display language of the message can be easily changed by changing the address table for performing the above search in accordance with the operation of the display language switching operator. This makes it possible to present messages to a wide variety of users in languages that are easy for them to understand, which has the effect of reducing the risk of erroneous operations due to lack of understanding. Furthermore, by adopting a structure in which message data is read through an address table, the number of display languages can be increased or changed very easily.
