Abstract

PURPOSE:To enable a character to be discriminated securely and easily, by converting an inputted printout code into a printout character pattern based on the content of a ROM selected by a changeover switch, and printing the printout character code. CONSTITUTION:A standard font character pattern ROM 5 stores standard character patterns for characters corresponding to printout codes 00-FF (hexadecimal notation). A special character pattern ROM 6 stores special character patterns for characters corresponding to printout codes 30, 42, 43, 44, 45, 46, 3F and standard character patterns for characters corresponding to other printout codes. The special character pattern ROM 6 stores special character patterns corresponding to standard character patterns o, B, C, D, E, F, O which might be difficult to discriminate when ink density becomes low. When the print out codes 30, 42, 43, 44, 45, 46, 4F are inputted, 0, B, C, D, E, F, O are printed if the standard font character pattern ROM 5 is selected by a changeover switch 4. If the special character pattern ROM 6 is selected, the special character patterns corresponding to the standard character patterns are printed.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a printer device, and particularly to a printer device that allows printed characters to be easily and reliably identified even when the density of the printed characters becomes low. The present invention relates to a printer device.

[Conventional technology]

When a printing code indicating a character consisting of characters is input, a conventional printer apparatus converts the input printing code into printing characters by referring to a character pattern ROM that stores character patterns corresponding to the printing code. This converted printing character pattern is then printed on printer paper. In other words, the conventional printer apparatus prints only one type of character pattern for the same input print code.

[Problem that the invention seeks to solve]

The conventional printer device described above prints one character per character.
Since it is only possible to print different types of character patterns,
It usually uses a standard character pattern that can be used in public places. Therefore, if the ink density becomes thin or the printed characters are removed from the copy machine.

When sent through a facsimile device, etc., 0 (zero) and O (oh), 8 (hachi) and B (bee), 0 (oh) and C (c), 0 (oh) and D (day), E ( There was a problem that it became difficult to distinguish between E) and F (F), etc.

The present invention solves the above-mentioned problems, and its purpose is to enable characters to be reliably and easily identified even when the ink density becomes low.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a printer device that prints a print character pattern of characters corresponding to an input print code, in which a standard character pattern of each character is stored in correspondence with the print code. a second ROM in which special character patterns for specific characters among the characters and standard character patterns for other characters are stored in correspondence with printing codes; a changeover switch for selecting either one of the second ROMs; and a changeover switch for converting the input printing code into a printing character pattern based on the memory contents of the ROM selected by the changeover switch; The apparatus is provided with a printing means for printing an output character pattern.

[For production]

Even if the same printing code is input, the first ROM is selected by the changeover switch or the second ROM is selected.
The character pattern of the printed characters differs depending on which ROM is selected. Therefore, a special character pattern that can be reliably identified even when the ink density becomes thin (for example, O (a pattern like n for (.)) is stored in the second ROM, and the switching If the second ROM is selected by a switch, even when the ink density becomes low, it becomes possible to easily and reliably identify printed characters.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of main parts of an embodiment of the present invention, including a printed code receiving section 1 that receives a printed code from an output port (not shown) on the processing device side, and a printed code receiving section 1 that receives a printed code from an output port (not shown) on the processing device side. A printing character pattern converting section 2 that converts the printing code from the . and a changeover switch 4 for selecting either one.

FIG. 2(a) and (bl are diagrams showing an example of the storage contents of the standard version character pattern ROM5 and special character pattern ROM6, respectively.The standard version character pattern ROM5 has printing codes 00 to FF (hexadecimal display) Standard character patterns of characters corresponding to are stored.Furthermore, the special character pattern ROM6 includes printing codes 30.42°43, 44.
Special character patterns of characters corresponding to 45.46.4F and standard character patterns of characters corresponding to other printing codes are stored. In this case, special character pattern ROM6
Standard character patterns O, B, C, D, E, which may be difficult to distinguish if the ink density becomes thinner.
Special character pattern building corresponding to F, O, ■, Ω,
El, E, Dan, and 100 are memorized.

The printing code from the output port on the processing device side is received by the printing code receiving section 1 and transferred to the printing character pattern converting section 2. By referring to the standard version character pattern ROM 5 or special character pattern ROM 6 selected by the changeover switch 4, the printed character pattern conversion section 2
The print code received from the print code receiving section 1 is converted into a corresponding print character pattern and sent to the print control section 3, and the print control section 3 prints the specified print character pattern on printer paper.

Therefore, printing code 30.42.43.44.45.4
When 6°4F is input, if standard version character pattern ROM5 is selected by changeover switch 4, 0,
If B, C, D, E, F, O are printed and special character pattern ROM6 is selected, then l, ■.

C, f), E, F, and O will be printed, so even if the ink density becomes thinner and it becomes difficult to identify the printed characters using the standard character pattern,
By selecting the special character pattern ROM 6 using the changeover switch 4 and printing using the special character pattern, characters can be easily and reliably identified.

Although not explained in the above embodiment, the special character pattern ROM 6 can be created by the user using a ROM writer or the like, for example.

〔Effect of the invention〕

As explained above, the present invention provides a second ROM that stores special character patterns in addition to the first ROM that stores standard character patterns, and uses a changeover switch to select the first, second, and third ROMs. Since either one of the second ROMs can be selected, the standard character pattern in the first ROM may be difficult to identify if the ink density becomes thin. By selecting the second ROM in which the special character pattern for that character is stored using a changeover switch, the printed character can be easily and reliably identified, and then the first ROM can be selected. This makes it possible to print using standard character patterns that are commonly used in public places. Therefore, it is suitable to apply the present invention to a printer device that prints software programs and the like that particularly require accuracy of characters, and prints official texts and the like.
