Description

[Detailed explanation of the idea]

[Industrial Application Field] The present invention relates to a text display device for copying machines, facsimile machines, printers, etc., which can display texts in multiple languages simultaneously or alternately. [Prior Art] As a text display device, there is one shown in FIG. 3, for example. This text display device is patent application No. 58-213665.
It is composed of a text control section 20, a display control section 21, and a display section 22 using an LED, LC, CRT, etc., and is adapted to be applied to, for example, a copying machine. The text control unit 20 has text ROMs 1a, 1b, and 1c in which display texts in English, French, and Japanese with the same meaning and content are stored in the same address, respectively;
Based on the language selection signal and status signal sent from the main body control unit, the text control ROM 2 stores a program for selecting and reading the text ROM and display text of the language concerned, and the intermediate results of processing by the CPU 8 are temporarily stored. RAM3 and ROM
a decoder 4 that selects one of 1a, 1b, 2 and RAM 3 according to a parallel binary code given from the main body control unit; and a text ROM 1a or 1b.
Gate circuits 5a and 5b select chips based on the AND of the decoder 4 and the language selection signal 7.
, the language selection signal 7 is inverted and the gate circuit 5
Inverter 6 that outputs to a and text control ROM
an arithmetic control unit (CPU) 8 that processes input data based on a program stored in the main unit 2; and an input interface 9 that internally receives a command signal (binary code) supplied from a main body control unit (not shown).
, an input port 10 having a function of exchanging information sent and received within the display control unit 20, and a control bus 11 that connects the port 10 with each ROM, RAM, and CPU 8 to transmit information.
a, an address bus 11b, and a data bus 11c. The display control unit 21 includes a refresh ram 12 that temporarily stores character code strings of display text sent from the text control unit 20 and commands related to display;
a character generator 13 that generates a character pattern based on the character code string; and a display section 2.
2, a timing counter 15 that controls the cooperative operation of each of these elements, an address selector 16 and a power supply 17 that assist this. An overview of the above configuration is as follows:
When the user operates the language selection switch on the console and selects either English or French, the language selection signal is input to the control unit of the main unit of the copier (hereinafter referred to as the main unit control unit), and then displayed from the main unit control unit. It is output as a command signal to the device. Further, the main body control section outputs a signal representing the internal state of the copying machine or the like (hereinafter referred to as a state signal; for example, a signal representing "toner shortage", etc.) to the text display device as necessary.
The text control unit 20 receiving this signal selects a display text corresponding to the text ROM and internal state of the language based on the text selection signal 7 and status signal sent from the main body control unit, and selects the display text corresponding to the text ROM and internal state of the language, and selects the display text corresponding to the text ROM and internal state of the language. It is read out as a character code string and output to the display control section 21. Then, the display control section 21 converts this character code string into a character pattern, and scans and drives the display section 22 to display the displayed text in the selected language. Next, among the above configurations, the functions of the decoder 4 will first be explained based on FIG. 4 A, B, and C. Now, the state in which there is input to the terminal is indicated by H, and the state in which there is no input is indicated by L. H and L may be considered to have the same meaning as 1 and 0, respectively. Now, if the inputs of the input side and terminal of the decoder 4 are both L, the output of the output side terminal is L, as shown in Fig. 4A.
, the outputs of the terminals both become H, and the sentence selection
A chip selection signal L is input to the CS terminal of the ROM 2, and this element is selected. In addition, when H is input to the input side terminal of the decoder and L is input to the terminal, the output of the same output side terminal becomes L, and the output of the same terminal becomes H. Therefore, the gate circuits 5a and 5b L is input, and in this case, one of the text ROMs 1a and 1b is selected as will be described later. Similarly, when the input side and terminal inputs of the decoder are H and L, respectively, RAM3 is selected. Here, among the memories 1a, 1b, 2, and 3, the one selected by the decoder 4 functions effectively, and the others temporarily lose their functions. Next, when the user selects English by operating a language selection switch (not shown) on the console, etc., the language selection signal is H, and this signal is for French sentences.
ROM1b contains the English text ROM as is.
In order to pass through the inverter 6, the signal is inverted and input to 1a as L. Therefore, the gate circuit 5a
The input signals are L and L, and the gate circuit 5a opens and outputs L, which is input as a chip selection signal to the CS terminal of the English sentence ROM 1a, and the English sentence is output.
ROM1a is selected. On the other hand, since the inputs to the gate circuit 5b are L and H, and the gate circuit 5b outputs H, the French text ROM1b is not selected. Here, suppose that, for example, a "toner shortage" situation occurs in the main body of a copying machine or the like, and a status signal indicating "toner shortage" is output from the main body control section to the text control section 20 of the text display device. do. This status signal is taken internally by the input interface 9, and is sent to the input port 10 and the data bus 11.
Input to CPU8 through c. Based on the program stored in the text control ROM 2, the CPU 8 selects the display text "PLEASE ADD TONER" with text number 2 corresponding to the state. Each sentence ROM1a of the sentence
If the addresses in 1b and 1b are both 00000010, this address signal is sent from the CPU 8 to the input port 9 via the data bus 11c, and then to each memory 1a, 1b via the address bus 11b.
Input to 1b, 2, and 3. Next, a read command is input to each of the above-mentioned memories through the control bus 11a, but in this case, the text ROM switching circuit (decoder 4, gate circuit 5) functions effectively.
English sentence ROM1a selected by the circuit section consisting of a, 5b and inverter 6)
The display text “PLEASE
ADD TONER (please replenish toner)" is read out as a character code string, and data bus 1
1c to the refresh ram 12 of the display control section 21 and stored there. In the display control unit 21, a character generator 13 generates a character pattern (video signal) based on the character code string stored in the refresh ram 12.
The x driver 14a and the y driver 14b scan and drive the display section 22 to display the character pattern on the display section 22. Even if the user selects French and the language selection signal is H, the French text ROM1b can be retrieved by the same operation.
is selected, a display sentence with the same meaning and content is read out as a French character code string, and displayed on the display section 22. Above, we have explained the case where the display languages are two languages, but if the display languages are three or more languages, the language selection switch and text ROM gate circuit can be added according to the number of languages to expand the functions of the coder. This can be dealt with by: [Problems to be solved by the invention] However, in the case of the text display device described above,
Since this selection is made only for languages that require multiple text ROMs, this selection not only means that only those who can understand the displayed language will be able to understand the content, but will also be unable to perform operations corresponding to the displayed content. There is an inconvenience that this cannot be done. [Means and effects for solving the problem] The present invention was made in view of the above, and in order to display multiple frequently used languages, it is possible to display multiple text ROMs in different languages. To provide a text display device that allows text ROMs in a plurality of required languages to be selected simultaneously or sequentially. [Example] Hereinafter, a text display device according to the present invention will be described in detail. FIG. 1 shows an embodiment of the present invention, which includes text ROMs 1a, 1b, and 1c in three languages: English, French, and Japanese. In this embodiment, the same reference numerals are used for the same parts as in FIG. NOR gates 18a, 18b, 18
Each of the text ROMs 1a, 1b, and 1c is selected by each of the text ROMs 1a, 1b, and 1c. One input terminal of each of NOR gates 18a-18c is connected to a terminal of decoder 4, and the other input terminal is connected to a respective line of language selection input signals _S1 , _S2 , _S3 . In addition, NOR gates 18a to 18c
Each output terminal is connected to the chip select ( ) terminal of each of the text ROMs 1a to 1c. The language selection input signals S ₁ to _{S 3} are given H level and L level signals in six modes as shown in the table below to specify a single language or a plurality of languages.
