A dot image creation method and apparatus for selectively operating a pin of the dot print head by storing a pin operation signal of a dot unit.

A dot printer is an impact printer that can print information by tapping a print ribbon. That is, the printer is a method of printing text and picture information on a piece of paper as a set of small dots. Recently, a lot of companies are looking for dot printers with low purchase price and low maintenance cost, instead of expensive laser printers, especially for government offices and financial companies. As mentioned above, the dot printer is attracting attention because the maintenance cost of ribbon or printing paper is low and there is almost no residual failure due to the durability of the semi-permanent head. In addition, it is not only cheaper than laser printers, but also supports paper feeding methods and paper suitable for various office environments such as printing tax invoices using paper or cobalt paper.

In particular, in the case of printing predetermined information, the automated teller machine must print the information on a plurality of sheets such as a paper for providing the user, a paper for bank storage, and a paper for storing in the automated teller machine. Therefore, by using a dot printer that prints information in an impact manner, the same information can be printed on several sheets of paper at once.

In a conventional dot printer, an image is printed using a time delay. As an example, Korean Patent Application Publication No. 10-1999-7011556 relates to a dot matrix print head having a single armature assembly and a method of operating the same. A timing device is used to control a predetermined information by controlling the moment at which the ink ribbon is driven. Disclosed is a dot printer head for printing. However, when the dot image is created using the dot printer head, calculation of the operation time of each of the print wires connected to the dot printer head has to be performed.

Therefore, there is a need for a new dot image creation method and apparatus that can solve the above problems.

SUMMARY OF THE INVENTION The present invention has been made to improve the prior art as described above, and extracts pixel information corresponding to pin position information of a dot printer head from image data to be printed, and pins of a dot print head in response to the extracted pixel information. An object of the present invention is to provide a dot image generating method and apparatus for selectively operating pins of the dot print head by storing operation signals in head units.

It is also an object of the present invention to provide a dot image creation method and apparatus capable of printing information using various types of dot printer heads.

In addition, the present invention provides a method and apparatus for creating a dot image that makes it possible to easily implement the overall durability configuration of a dot print by implementing the operation for each print wire at the same time without a predetermined time difference. The purpose.

In order to achieve the above object and to solve the problems of the prior art, the dot image creation method according to the present invention comprises the steps of: maintaining the pin position information of the dot printer head, obtaining image data to be printed, the obtained image data Extracting pixel information corresponding to pin position information of the dot printer head from the data; storing pin operation signals of the dot printer head in a predetermined memory in units of heads corresponding to the pixel information; and storing the stored dots. And selectively operating the pin of the print head with reference to a pin operation signal of the print head.

Further, a dot image generating apparatus according to another aspect of the present invention includes a print head including a plurality of pins, a pin head information holding unit for holding pin position information of a dot printer head, and a print image for printing a predetermined image. A pixel information extracting unit for acquiring data and extracting pixel information corresponding to pin position information of the dot printer head from the obtained image data, and obtaining a pin operation signal of the dot printer head corresponding to the pixel information. A storage unit for storing the head unit in the memory, and a pin operation unit for selectively operating the pin of the print head with reference to the pin operation signal of the dot printer head stored above.

Hereinafter, with reference to the accompanying drawings will be described in detail a dot image creation method and apparatus according to the present invention.

1 is a diagram illustrating a flow of a dot image creation method according to an embodiment of the present invention.

First, in step 101, pin position information of the dot printer head is maintained. The dot printer head may include a plurality of pins, and each of the plurality of pins may be driven independently. In addition, the position of the pin may be different from each other according to the type of dot printer head, such as straight, cross-shaped, diamond-shaped, circular.

2 is a view showing an example of the pin position information of the dot printer head according to an embodiment of the present invention.

As shown in FIG. 2, N pins may be located in the N * N array. For example, when the type of the dot printer head is diamond type and the array of 6 * 6, six pins may be located at ①, ②, ③, ④, ⑤ and ⑥, respectively. Therefore, the pin position information of the six dot printer heads can be maintained before printing predetermined information, and the pins of the six dot printer heads can be one head unit.

In step 102, image data to be printed is obtained. The image data may be composed of a plurality of pixels. When the dot printer head is an N * N array, the image data can be acquired as much as the size of the N * N array. For example, when the dot print head is an array of 6 * 6, data of an array size of at least 6 * 6 may be obtained whenever image data is acquired once.

In step 103, pixel information corresponding to pin position information of the dot printer head is extracted from the obtained image data.

The obtained image data is the same as the head unit of the dot printer head, and thus one or more pixels corresponding to pin position information of the dot printer head of the portion to be printed from the image data and pin position information of the dot printer head of the portion to be not printed. Information can be extracted.

In step 104, the pin operation signal of the dot printer head is stored in a predetermined memory in units of heads corresponding to the pixel information.

The pin operation signal may be information indicating whether a dot printer head is pin-operated, and the head unit may be an array of pins included in the dot printer head. For example, referring back to FIG. 2, N pins included in the N * N array may be head units. That is, in the case of the arrangement of 6 * 6, the pins of six dot printer heads including ①, ②, ③, ④, ⑤ and ⑥ may be one head unit. Therefore, an operation signal is stored in a predetermined memory for each pin of six dot printer heads as one head unit, and the six dot printer heads may be operated according to the operation signal. Hereinafter, a method of extracting pixel information will be described with reference to FIGS. 3 to 4.

3 to 4 are diagrams illustrating an example of a method of extracting a pin operation signal of a dot printer head corresponding to pin position information of the dot printer head according to one embodiment of the present invention.

First, referring to FIG. 3, when the dot print head prints information while moving from side to side, the pixel information of the image data corresponding to the pin position of the dot printer head is extracted based on the first vertical line of the acquired image data. do. For example, the operation signal of the pin can be determined as "T" when the pixel to be printed is located at the pin position of the predetermined dot printer head, and "F" when the non-printing pixel is located. Therefore, the operation signal of the head unit for the image data may be "①-F, ②-F, ③-F, ④-F, ⑤-T, ⑥-F.

After acquiring the operation signal of the first head unit pin from the image data, the operation signal may be acquired based on the second vertical line of the image data. Therefore, referring to FIG. 4, the pixel information extracted based on the second vertical line may be "①-F, ②-T, ③-T, ④-T, ⑤-F, ⑥-F".

With respect to the subsequent image data, it is possible to determine the operation information of the pin of the dot printer head corresponding to the image data in one head unit in the same manner as described above.

5 is a diagram illustrating an example of a method of storing pin operation signals of a dot printer head in a unit of head in a memory according to an embodiment of the present invention.

As shown in FIG. 5, the pin operation signals of the head unit may be sequentially stored in a predetermined memory. First, the first pin action signal "X, X, X, X, O, X" is stored in the memory, and the second pin action signal "X, O, O, O, X, X "may be stored in the memory. That is, when the pin operation signal is "F", the ribbon does not print the pixel by performing the operation of the pin, and when the pin operation signal is "T", the operation of the pin is performed. You can have the ribbon on that pin print the pixel.

The memory may be a storage means such as a RAM. The pin operation signal determined as described above may be sequentially stored in a memory, and the pin may be operated according to the stored pin operation signal to print corresponding image data.

Finally, in step 105, the pin of the print head is selectively operated with reference to the pin operation signal of the stored dot printer head.

In the dot image creation method according to the present invention, unlike a conventional dot image creation method, a plurality of pins included in one head unit simultaneously prints corresponding image data without time delay using a predetermined timing device. Therefore, when the pin operation signal of the dot print head is "F" with reference to the pin operation signal of the dot print head stored in the memory, the operation of the corresponding pin is not performed so that the ribbon of the pin does not print the pixel. If the pin operation signal is “T”, the ribbon of the pin may print the pixel by performing the operation of the pin.

For example, referring back to FIG. 5, when the first pin operation signal stored in the memory is "X, X, X, X, O, X", only pin "5" of the dot print head is operated. The pins "①, ②, ③, ④, ⑥" can not be operated to print the image data. Next, refer to the second operation signal "X, X, X, X, O, X" so that only "②, ③, ④" is operated, and the remaining pins "①, ⑤, ⑥" are controlled to be inoperative. Can be.

Hereinafter, a dot image creating apparatus according to the present invention will be described with reference to FIG. 6.

The print head 601 includes a plurality of pins and prints a predetermined image. In addition, the print head 601 may include a driving unit for independently driving the plurality of pins. Therefore, the corresponding pin can be selectively operated according to the operation signal of the pin.

The pin position information holding unit 602 holds pin position information of the dot printer head. The location of the pin may be different depending on the type of dot printer head such as straight, cross-shaped, diamond-shaped, and circular.

The pixel information extracting unit 603 obtains image data to be printed and extracts pixel information corresponding to pin position information of the dot printer head from the obtained image data. The image data may be composed of a plurality of pixels. Therefore, the pixel information extracting unit 603 obtains the pin position information of the dot printer head of the portion to be printed from the image data and the dot printer head of the non-printed portion, because the acquired image data is the same as the head unit of the dot printer head. Extract one or more pixel information corresponding to the pin position information of.

The storage unit 604 stores the pin operation signal of the dot printer head in a predetermined memory in units of heads corresponding to the pixel information. The pin operation signal in units of heads may be stored in a predetermined memory in order.

The pin operation unit 605 selectively operates the pin of the print head with reference to the stored pin operation signal of the dot printer head. If the pin operation signal of the dot print head is "F", the operation of the corresponding pin is not performed. Therefore, the ribbon of the corresponding pin does not print the pixel. If the pin operation signal is "T", the operation of the corresponding pin is performed. This allows the ribbon of the pin to print the pixel.
