Description

[Detailed Description of the Invention] [Summary] Two types of kanji pattern generators (hereinafter referred to as kanji CG, character generators) that generate kanji patterns by specifying codes are popular.

Printers are equipped with CG for each type of kanji to support this, but the number of models will increase.

The present invention provides a printer capable of replacing two sets of kanji CG, and determines the type of the kanji CG installed and converts the code by comparing it with a designated code.

[Industrial application field]

TECHNICAL FIELD The present invention relates to an improvement in a kanji control method in a kanji printer.

There are two types of serial kanji printers (hereinafter referred to as kanji printers): an image type that prints by inputting a character pattern from a host computer, and a code type that has a kanji CG installed in the printer and prints by inputting a kanji code.

The kanji patterns and kanji codes recorded in this kanji CG are based on JISC6226, but 1
The one established in 1978 (hereinafter referred to as the old JIS) and the one revised in 1983 (hereinafter referred to as the new JIS) are contradictory.

The difference between the new JIS and the old JIS mentioned above is the change in the kanji code and the change in the pattern (abbreviation method) due to the exchange of the 1st level and the 2nd level, but the old JIS.

■Printers equipped with old JIS kanji CG are being supplied to users who use the S pattern.

On the other hand, it is also necessary for the user of the printer to make the printing code sent by the host computer compatible with the printer, and some printers are emerging that convert the code into its own kanji CG on the printer side and print it.

In this way, the new JIS or old JIS kanji CG
There is a demand for printers that are equipped with kanji CG, and even those that convert codes into Kanji CG, and the number of models has increased, creating an obstacle to cost reduction.

Therefore, there is a need for a 1TJf printer that solves the above problems.

[Conventional technology]

A conventional example will be explained with reference to FIG.

Figure 3 (=1) is a block diagram of a kanji printer equipped with old JIS kanji CG and a new-old code conversion table for code conversion from new JIS to old JIS; Figure 3 (bl is a code conversion operation flowchart) It is.

In Figure 3 (al), the kanji code received by the host computer is stored in the reception buffer 3, and after receiving one line of code, the old JIS kanji CG4 is referred to.
The pattern is developed in the line buffer 8. Subsequently, the contents of the line buffer 8 are read by the printing section 7 and printed serially according to the spacing.

The above is the operation specified by the old JIS, but if the new JIS is specified before printing, when the kanji code is received, the new
The old code conversion table 5 is searched, and when a corresponding code is detected, the code is converted and stored in the reception buffer 3.

Thereafter, when the pattern is developed based on the received Haratsub 3, the old JIS pattern can be printed by specifying the new JIS code.

The above code was converted when received, but it was received as is (f
There is also a method of storing the data in the i-buffer 3 and converting the code when developing the pattern.

The same goes for printers equipped with the new JIS Kanji CG.

If there is an old JIS designation, the old JIS - new JIS
The code is converted and printed using the new JIS pattern.

[Problem that the invention seeks to solve]

As explained above, there are two types of kanji CG: the new JIS and the old JIS, and both are desired because their kanji patterns are different.

Moreover, with the revision from the old JIS to the new JIS, kanji characters were replaced between the first and second level, and as a result, the kanji code corresponding to that kanji was partially changed (more than 20 characters).

Therefore, in order to correspond to the kanji code on the host side, the new J
It would be possible to install both TS and old JIS Kanji CC, but this would be expensive, so some printers have appeared that convert the code to Kanji CG.

However, since the conversion method differs depending on the kanji CG installed,
There is also the problem that it is necessary to manufacture two models, which makes them expensive.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a kanji printer that is compatible with new JIS and old JIS kanji CG.

Means for Solving Problem C] For the above purpose, the kanji printer of the present invention has a code conversion table (10 ), a built-in means (l l) for determining the code type of its own kanji pattern generation unit, and a means (l l) for determining the code type of its own kanji pattern generation unit, which compares the commanded code type with the determined own code type, and also compares the code type transmitted based on the command. A means (12) for converting the printing code into the own code, and according to the designation of the code type, the printing code is converted into the code of the own Kanji pattern generating section and printed.

[Effect]

In other words, the type of the installed kanji CG is determined, and once the kanji CG type is specified, it is determined whether code conversion is possible or not, and the new JIS
- Determine whether the code conversion means is old JIS or old JIS=new JIS.

Therefore, if you prepare a code conversion table 2&If, you can use the same conversion control to support the old JIS and new JtS kanji CG, so you can use the new JIS.

All you need to do is replace the old JIS kanji CG, and the host does not need to be aware of kanji codes unless the printer's patterns are a problem.

〔Example〕

An embodiment of the present invention will be described with reference to FIG.

FIG. 2 (al is a block diagram of the kanji printer of the embodiment, and FIG. 2 (bl is an operation flowchart 1).

In Figure 2 fa), 13 is the new JIS or old JIS kanji CG, and 14 is the old JIS.
Old-new code conversion table for converting from IS code to new JIS code, 5 is from new JIS code to old JIS code
New → old code conversion table for converting to code, 1
5 is a setting switch for the operator to specify new/old to the printer; 16 is a code conversion unit that converts new-old and old-new codes; 17 is a new/old kanji that determines whether kanji CG 13 is old JIS or new JIS. CG discrimination unit, and the same reference numerals as in the narrow tube 3 (a) represent the same objects.

The operation will be explained below with reference to FIG. 2(b).

(11 The operator sets the host's kanji code using the setting switch 15.

(2) The old and new kanji CG determination unit 17 searches a predetermined area of the kanji CG 13 to determine whether it is new or old.

In the old JIS, the kanji code "
Since there is no pattern for "8th ward", the pattern is read by specifying "8th ward" and a predetermined "point", and if the pattern is empty, it is determined that it is the old JIS.

Also, in the old JrS, 22X2 of the 24X24 matrix
Only two areas are used, and a specific kanji character is specified and read to determine whether a pattern exists in a predetermined area.

(3) Based on the above settings and old/new discrimination, do not convert, New-old code conversion, Old → new code conversion, is commanded to the code conversion unit 16.

(4) When receiving a kanji code, if the main control unit 1 does not convert the code, it stores it in the reception buffer 3 as it is,
When there is a conversion command, the code conversion section 16 converts the code by referring to a predetermined code conversion table, and stores the converted code in the reception buffer 3.

Note that, as described above, code conversion may be performed when developing the pattern.

As described above, by simply specifying the new and old codes, a predetermined kanji pattern can be developed and printed, and by exchanging the kanji CG using a socket or the like, the new and old patterns can be easily selected.

In the embodiment, the setting switch 15 is used to designate the new or old, but the host computer may also designate the new or old.Alternatively, the determination of whether the device is new or old may be made when the power is turned on, and the type of the device may be recorded.

In addition, in the block diagram of FIG. 2 (al), the old-new code conversion table 14 and the new-old code conversion table 5 can be combined into the same table, and
6. The old and new kanji CG discrimination section 17 can be included in the main control section 1.

As a result of the above, users do not need to be aware of the new JIS and old JIS.
S only, old JIS only, new with code conversion, lrS,
Four old JIS models with code conversion can be combined into one model.

〔Effect of the invention〕

As explained above, the present invention provides a printer equipped with a means for determining the type of its own kanji CG and a means for converting the code according to the specified type, and is capable of handling new and old codes of the host. In addition to being easier, the printer can handle the new and old kanji by simply replacing the CG of the old and new kanji.
