Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording device that can create storage information for input information of a plurality of different systems.

[Prior Art] First, the meaning of the term character encoding system will be clarified. In Figure 2, 1 is an example of a code table, 00-7FH
(H is a hexadecimal code).

The shaded area 11 is the control code area with codes 00 to 20H:
ff-Door FH is the control code. A white portion 12 represents a character code area. The entire combination of codes in the character code area and codes in the control code area is called one type of character code system. Conventionally, in a recording device that outputs a pattern report in response to input code information, an information processing unit for multiple types of character code system information, for example, an ASCII code and a JIS code system, is provided in the device, or a cartridge is provided. There is a recording device that can handle a plurality of types of character code information by attaching and detaching a character code system, and converts code information manually entered into a pattern according to a selected character code system and outputs the pattern.

However, even in such a recording device, not only the character code but also the control code can be used to store information in different code systems, or the character code area and control code area can intersect with each other with information in other code systems. It was not possible to deal with cases where the code system information was For example, in FIG. 3, 2 is a diagram showing a code system different from 1, 21 is a control code area, and 22 is a character code area. Here, the code area 13 corresponding to the code 0'42H'' is a character code in FIG. 2, but is a control code in FIG. 3.

There has been a desire for a recording device that can correctly receive and record information of such different code systems.

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned points. Information on multiple types of code systems including control codes is prepared in advance in the device, and it is possible to respond to manual code information. The object of the present invention is to provide a recording device that selects a code system and performs a recording operation based on manually input code information.

[Means for Solving the Problems] In order to achieve the above object, the recording apparatus of the present invention has the following configuration.

That is, a recording apparatus that manually records code information is provided with a storage means for storing a plurality of types of code system information of different code systems, and a selection means for selecting the code system information of the storage means.

[Operation] The above configuration operates so that input code information of different code systems can be input and recorded.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the drawings.

[Description of Printing Apparatus (FIG. 1)] FIG. 1 is a block diagram showing the configuration of a printing apparatus according to an embodiment of the present invention. In the figure, 31 is a host computer that transmits data to the printing apparatus, and 32 is the main body of the printing apparatus of this embodiment. 33 is a microprocessor (MPU)
) and a ROM that stores its control programs and data, etc.
This is a control unit that is configured with a RAM and the like as a work area and controls printing of the apparatus. 34 is a code system information memory for giving meaning to the code transmitted from the host computer 31 as a specific character or control command, and 35 is a switch for selecting the code system of the code transmitted from the host computer. . 36 is a table pointer register for searching the code system table in the code system information memory 34 and converting the received code into a unique internal code. 37 is a code system register for storing the number of the currently selected code system, and 38 is a character pattern storage section for converting the internal code into a character pattern during printing. A dot printer section 39 forms a visible image on paper based on pattern data.

[Explanation of code system information (Fig. 4) Fig. 4 shows the table of the code system information memory 34 and the code system register 3.
7 and a table pointer register 36. This table converts input code information into an internal code.

The code system information memory 34 includes a code conversion table 44 based on n code systems.
The start address of each conversion table 44 corresponding to n is indicated by the table pointer register 36, and the table pointer register 36 is selected in accordance with the code system number of the code system register 37. This code system number is the number selected by the dip switch 35.

The code conversion table 44 consists of a code field 45 and an internal code field 46, the input code corresponds to the number in the code field 45, and the internal code in the internal code field 46 corresponding to the code in the code field 45 corresponds to the code in the code field 45. is a code for internal processing that includes all characters and meanings of all control codes included in the corresponding code system.

25 decodes the contents of the code system register 37 with a decoder, selects the pointer corresponding to the code system number of the table pointer register 36, and selects one of the code systems 1 to n in the code system information memory 34. . On the other hand, the received code is stored in the reception code register 23.
By manually inputting the value of the table pointer register 36 selected by the code system register 37 to the adder circuit 24, the internal code corresponding to the received code is read out.

[Explanation of Operation of Control Section (FIGS. 4 and 5)] Next, the operation of the control section 33 of this embodiment will be explained with reference to the flowchart of FIG. Note that this program is executed by the RO of the control unit 33.
It is stored in M.

When the program is started by inputting a power switch or a reset signal, the program first proceeds to step S1 and reads the value of the dip switch 35. In step S2, the code system number corresponding to the dip switch 35 is selected, and its value is set in the code system register 37. This determines which code system is selected from the code system information memory 34.

In step S3, data received from the host computer 31 is awaited. When the data is received, the process advances to step S4 and the data is taken in. Next, in step S5, the data is set in the reception code register 23. Step S6
The internal code is read from the code system information memory 34, and in step S7, if it is a character code, the character pattern corresponding to the internal code is read from the character pattern storage section 38 and sent to the printer section 39. At this time, in the case of a control code, normal printing control operations such as processing corresponding to each control code are performed, and the process returns to step S3 again to wait for the next data reception.

The steps will be explained in detail with reference to FIG.
Now, for example, the code system is set by the dip switch 35.
2” is selected, code system register 3
7 is set to 2'', and the decoder 25 selects ADR2 as the address in the table pointer register 36.

As a result, the conversion table 44 of code system 2 is used for code conversion. Here, the received data is “0”.
2'' is input, this code is set in the reception code register 23, and the adder circuit 24 inputs the table pointer register 36 and the reception code register 23.
The contents of are added, and as a result, the address signal ADR2+0
2 is output, and the internal code 400 corresponding to the code "02" in the code field 45 is read out.

Note that in this embodiment, the internal code is retrieved by calculating the address by adding the start address of the code conversion table and the received code, but the address is not limited to this, and a search by a program can also be used. Of course it's a good thing. Furthermore, although it has been described that the coding system is selected by the digital switch, the coding system selection command may be sent from the host computer.

As described above, according to this embodiment, a code system can be selected by an extremely simple operation, a recording device compatible with data of multiple types of code systems can be provided, and even the control code may be different from a computer of a certain code system. Since the recording device can be shared with other computers in the code system, the equipment investment is low for the user, and even when used separately, it can be used for other purposes.

[Effects of the Invention] As described above, according to the present invention, it is possible to provide a recording device that can perform a recording operation by receiving information of multiple types of code systems including information of different code systems for control codes. .
