Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a text display device that allows storage space to be used without wasting even if languages are different.

[Conventional technology]

As a conventional text display device, for example, a plurality of text storage areas such as 40 characters, 60 characters, 80 characters, etc. are set based on the maximum number of characters in sentences with the same content in each language of each country. Some devices store sentences by selecting a sentence storage area according to the maximum number of characters in the sentence. In this case, each of the sentences has a data section containing the text number and address at the beginning, and the text number of the data section is compared with the text number to be read, and the address is calculated from the number of characters stored at the beginning address.

When setting the text storage area, for example, if a sentence in English consists of 38 characters and a sentence in German with the same content is 41 characters, the corresponding sentence will have 41 characters stored in all languages. Select a 60-character text area that is possible.

[Problem that the invention seeks to solve]

However, in conventional text display devices, the storage area is divided into steps of, for example, 20 characters, so if only 38 characters are stored in a 60-character text storage area, 6O-38=2
1 (character) worth of memory is wasted. For this reason, there have been cases where operability has deteriorated when used in countries with languages where the total number of sentences is limited or where measures such as forcibly shortening the sentences have to be taken.

[Means and effects for solving the problem] The present invention has been made in view of the above problems, and in order to efficiently utilize the storage area, it is possible to add text to each text with an arbitrary data length. The storage section is provided with a text area where numbers and end codes are attached and stored consecutively, and a management area where text groups are divided into multiple parts and the text number and address at the beginning of each segment are registered. The present invention provides a text display device that searches and reads from the top address of the section containing the text.

〔Example〕

Hereinafter, the text display device according to the present invention will be explained in detail.

FIG. 1 shows an embodiment of the present invention, in which a text display device includes a copying machine control section 1 that controls each part of the copying machine by inputting signals from various sensors and an operation panel of the copying machine, and the control section 1. It has a text display control section 2 that manually inputs a signal and outputs a display signal corresponding to the signal, and a display 3 that displays a text corresponding to the display signal when the display signal is input. Text display control section 2
is a CPU (signal processing unit) 4 that performs arithmetic processing on input signals.
and an input interface 5 which accepts signals output from the output port 14 of the copying machine control unit 1, and which inspects the signals read from the interface 5 and determines the text to be output when no abnormality is found. A soft cassette 6 in which character code strings of a plurality of predetermined different display texts are stored, and a character code string read from the soft cassette 6 based on the determined text number information is stored and edited. The display timing is controlled by timing signals from a single sentence code editing RAM 7, a character generator 8 that generates a character dot pattern based on the memory contents of the RAM 7, and a timing counter circuit 13, and the display timing is controlled according to the pattern signal from the character generator 8. A shift register 9 that outputs a drive signal, an X-driver 10 that is driven by the drive signal and outputs a lighting signal that lights up dots on the display 3 according to the character pattern, and an X-driver 10 that develops a timing signal and outputs a lighting signal that lights up dots in accordance with the character pattern. Decoder 11 that outputs a drive signal
and a Y-driver 12 that is driven by a drive signal to dynamically display a character pattern based on the lighting signal. As the display 3, a liquid crystal or a fluorescent display tube is used.

As shown in FIG. 2, the soft cassette 6 stores an area where a control program is stored, a text area where sentences are stored, and the text number and address of each text stored in the text area. It has a management area. The text area is divided into sections that fit within the maximum text search and readout time allowed for memory formation (the maximum time is for the search and readout of the text stored at the end of each section). The text number and address of the first text in each section are stored in the management area. Further, each sentence has a different length and is assigned a sentence number, and a code indicating the end of the sentence is attached at the end of the sentence. Then, the memorization is done in the order of sentence numbers.

Based on the above configuration, text display operations will first be explained.

For example, when the user temperature of the fixing section of a copying machine reaches a predetermined value, the copying machine control section 1, which manually inputs a temperature signal, outputs a control signal corresponding to "Copy ready". This control signal is composed of several to several tens of data per transfer data, is controlled by a transfer synchronization signal generated by the copying machine control section 1, and is input to the text display control section 2. In the text display control section 2, the control signal is decoded by the CPU 4 (according to the programs of SoftBank Cards I to 6) and the corresponding text number is determined. When an address in the soft cassette 6 corresponding to the determined text number is designated, the corresponding character code string is transferred to the RAM 7. This character code string is used as a part of the address for the character font (font) 9 stored in the soft cassette 6, and is written into the RAM 7 while being access-controlled by the signal from the timing counter I3. A character generator 8 generates a character pattern based on the contents stored in the RAM 7, and this display pattern is read out and taken into a shift register 9. When the shift register 9 drives the X-driver 10 and outputs a lighting signal, the Y-driver 12 sequentially scans the display 3 using the dynamic lighting control signal and displays "Copy ready".

Next, the formation of text memory in the soft cassette 6, and methods for searching and reading the text will be explained. As mentioned above, the text storage area of the soft cassette 6 is divided into a management area and a text storage area, and the text storage area stores sentences of various lengths, each with an end code at the end. , a predetermined search index table suitable for the speed required for text search and reading is provided in the management section.

Here, as an example, a case will be described in which a text with text number 85 is searched for and read out.

When the signal from the copying machine control unit 1 is received, its inspection (for synchronization signal errors, etc.) is completed, and document number 85 is determined based on the document number determination sequence, 3 in the search index table in the management area is records (1, 83, 1
21), the first information (the second information is the address)
The number to search from the text number that is (85 in this example)
, and the number closest to the search target number (85) is selected. In this example, the document number to be searched is 85, so 83, which is closest to this number, is selected and its address information full2013 is obtained. A dummy read is performed from this address value 2013 until two end records are read (that is, the difference from 85 is 2),
All processing ends when there is text data that corresponds to the next data, and when it is read up to the end record. Note that the average search speed can be adjusted by the number of records in the search index table in the management area.

〔Effect of the invention〕

As explained above, according to the text display device of the present invention, a text number close to the text number to be read is searched, and the text of the target text number is read by sequentially skipping the address of the number difference from the address of the number. Because I did it like this,
Each sentence can be stored consecutively, eliminating blank spaces in the memory and making effective use of the memory possible.
