Description

[Detailed Description of the Invention] [Field of Application in Business A] The present invention relates to a character output device that processes input information and outputs it as a character pattern, and particularly to a character output device that processes input information and outputs it as a character pattern. The present invention relates to a character output device equipped with a so-called dump function.

[Prior Art] In conventional character output devices of this type, all code values of input information transmitted from a data source are processed as needed when checking for troubles in the input system, output system, etc., or during periodic maintenance inspections. Solid printout is performed on recording paper in hexadecimal format.

[Problems to be Solved by the Invention] However, in such conventional devices, the encoding system for each character pattern that can be outputted is generally limited to one type, so when input information of different encoding systems is input, This has the drawback that a character pattern different from the character pattern intended by the user is output, and it is not possible to properly check input information.

For example, Figure 6 shows an example of the dump output when EBCDIC code input information is input when the device can only handle ASCII codes. , 5b, 5c, 5j
.

The input codes for 5e are different! , $, *, ), ;, but since the device is designed to display them using the ASCII code system, Z, [, ¥.

] is output, making it impossible to check the input information.

As the printer section 14, various printers such as an inkjet printer, a thermal transfer printer, and a laser beam printer can be used.

FIG. 3 shows an example of the arrangement (memory map) of the above-mentioned character pattern generator 9, where 21 is font information in which the address of where the information of each character set corresponding to the input code system starts is stored. A section 22 is a font storage section in which pattern information and the like of each font are stored.

The font storage section 22 stores the type of code system, for example, JIS.
Code (J), ASII:II code (A)
, EBCDIC code (E), etc. are provided for each of a plurality of code systems.

FIG. 4 shows an example of the internal configuration of the font storage section 22 shown in FIG. Here, 22-1 is a character set information section storing information such as the code system, character width, character height, character type, etc. of the character set corresponding to the input code, and 22-2 is the character pattern for each code. This is the character set pattern storage area where is stored.

Next, an example of the operation of the embodiment of the present invention shown in FIG. 2 will be explained with reference to the flowchart shown in FIG.

First, in the standby routine, when data is transmitted from the data source 1, this program is started and the received data is temporarily stored in the input buffer 4 (step Sl). After that, when reception from data source 1 is completed, input buffer 4
In step S2), the type of code system of the input character code is determined by referring to the code system register 8 based on the first sent code system identification code, and the input information is read out in units of input codes. The type of coding system is determined (step 53).

Next, it is determined whether or not the manual key of the dump instruction key 13 is turned on (step S4), and if there is no dump system,
Decided. Normal output processing by pattern conversion in the code system is executed (step S5).

When dump output is instructed by the dump instruction key 13, the next data is read from the input buffer 4 (step S6), and it is determined whether the read data is a control command (step S7); if it is a control command, In step S, the font information unit 21 of the character pattern generator 9 is searched for the storage address of the control pattern in the determined code system.
8), write the searched pattern address and input code to the page buffer 10 (step 510);
If the code read from the input buffer 4 is a character code other than a control command, the character pattern storage address in the determined code system is searched in the font information section 21 of the character pattern generation @9 (step S9).

The pattern address obtained is written to the page buffer 10 together with the input code, position information, character type obtained from the character set information section 22-1, etc. (step 510).
).

Next, the next data is read from the power buffer 4 (step 511), and it is determined whether or not the read code is a code indicating the data end (step 512). If the determination is negative, the process returns to step S7 described above. Step 5
The processes from 7 to S'l2 are repeated until an affirmative determination is made in step 512.

Thereafter, when the code read from the input buffer 4 reaches the data end, the contents of the page buffer 10 are converted into a character pattern by referring to the character set pattern storage section 22-2 of the character pattern generator 9, and the output image buffer 11 converts the contents of the page buffer 10 into a character pattern. Expand on top (step 513). When the expansion to image buffer 11 is completed, image buffer 1
1 outputs a print signal (video signal) in the form of a character pattern to the printer section 14 through the interface 12, and causes dump output printing to be performed on a recording medium such as paper (step 514). Then it returns to the wait routine.

For example, as shown in FIG. 6, the format of the output result from the printer 14 is such that the input code value is displayed in hexadecimal code on the left side 31, and the character pattern output represented by the manual code is displayed on the right side 32. Note that in this example, since character patterns are output according to the code system, a dumb list of character patterns that match the input code system can be obtained.

In this embodiment, a predetermined specific character pattern for the control code is used in the output display of the control code, but if further output processing such as shading is applied to the character pattern and the manual code value display, the control It becomes easier to distinguish from character data other than codes. Furthermore, the output system is not limited to printers, but can also be applied to display devices such as CRTs.

[Effects of the Invention] As explained above, according to the present invention, the type of coding system of input data is identified and the dump output of human data is performed in accordance with the type of coding system. Errors in input received data can be detected quickly, data verification work becomes easier, and other effects can be obtained.
