Description

Double-color 24-needle stylus printer

Technical Field

The utility model relates to a pin printer equipment field especially relates to a 24 pin printer of double-colored.

Background

In the dot printer, 24 dots of the printhead strike the ink ribbon and the paper to print the ink on the ink ribbon or the copy layer on the paper to the paper below, thereby forming a pattern or a font.

A stylus printer is a commonly used printer. The method is widely applied to the industries of office, finance, insurance, tax, logistics, government windows and the like. The stylus printer can print multi-layer paper and can print various papers such as single-page paper, joint-page paper, bankbook and the like, so that the stylus printer cannot be replaced by other types of printers in many industries and is still widely used.

Under the influence of the principle of the dot impact printer using the ribbon for printing, the printing resolution and other factors, the dot impact printers used in the market can only print in monochrome basically. However, with the development of industry and technology, it is desirable to realize two-color printing in addition to the single-color printing function in some fields. For example, with the application of electronic seals, some documents and stamps on documents can be printed. To satisfy the customer experience, it is desirable that the characters be printed in black and the chapters be printed in red. This requires that the stylus printer have a dual color printing function.

The double color printer on the market has been realized by switching the color tapes back and forth, and thus a complicated switching device is required. This leads to problems such as increased machine cost and reduced reliability.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, an embodiment of the present invention includes:

a24-pin dual-color printer uses a 24-pin print head in conjunction with a dual-color ribbon. The 24-pin print head used, in order to accommodate two-color printing, has been specifically defined for the arrangement of pins: the 24 needles are divided into a first needle group and a second needle group, as shown in fig. 2, each group has 12 needles, the 1-12 needles are a first needle group 21, the 13-24 needles are a second needle group 22, and a gap is left between the two groups.

As shown in fig. 1, the printer uses a two-color ribbon 13, two colors of which are arranged side by side on a ribbon base, 11 and 12, respectively, and the colors can be defined as required. The interface 14 of the two colors needs to be positioned according to the situation of cooperation with the print head.

In a 24-pin print head, the vertical spacing between adjacent pins is the same in the same pin group, i.e., all pins are vertically projected in the same pin group, the vertical spacing between the projections of adjacent pins is equal, and the vertical spacing between adjacent pins in the first pin group may also be equal to the vertical spacing between adjacent pins in the second pin group.

As shown in fig. 3: the vertical spacing between the 1 needle and the 2 needles, and between the 2 needles and the 3 needles, the … … 11 needles and the 12 needles are respectively set as spacing 1 and spacing 2 … … spacing 11, and then the vertical spacing between the 13 needles and the 14 needles, and between the 14 needles and the 15 needles, the … … 23 needles and the 24 needles are set as spacing 13 and spacing 14 … … spacing 23, so that the distances from spacing 1 to spacing 11 and from spacing 13 to spacing 23 are equal; the vertical spacing between the 12 needles and the 13 needles is a spacing 12, the spacing 12 is also the shortest spacing between the first needle group and the second needle group, and the spacing 12 is 7 times or more the vertical spacing (spacing 1, 2, etc.) of the adjacent needles.

When double-colored typewriter ribbon and printer head cooperation were used, the first kind of colour 11 of typewriter ribbon is printed to first group of needle 21 of printer head, another kind of colour 12 of typewriter ribbon is printed to another group of needle 22, two kinds of colours juncture 14 will be located the 12 needles of printer head and the intermediate position between the 13 needles, because the typewriter ribbon is in process of production, the juncture 14 of two kinds of colours has certain error, the typewriter ribbon is printing the in-process simultaneously, move forward always, in the motion process, the typewriter ribbon has certain change with the cooperation position of printer head, in addition, the setting up of double-colored typewriter ribbon and interval can also guarantee that the cooperation between double-colored typewriter ribbon and the printer head leaves the surplus, can effectually prevent the color mixing, improve printing.

In the first needle group, the odd-numbered needles and the even-numbered needles are respectively positioned at two sides, and at each side, each needle and at least one adjacent needle are arranged in a staggered manner, namely the needles at each side are not arranged into a straight line and are in an arc-shaped structure; the odd-numbered needles of the first needle group and the odd-numbered needles of the second needle group are positioned on the same side, and the even-numbered needles of the first needle group and the even-numbered needles of the second needle group are positioned on the same side. The arrangement mode can ensure that the number of the simultaneously-discharged pins is reduced to the minimum in the printing process, and the noise of the printer can be effectively reduced.

The utility model relates to a double-colored 24 needle impact printer's beneficial effect is: the color mixing of two colors can be effectively prevented in the printing process, in addition, the printer can be ensured to realize double-color printing under the condition of not making large changes, and the printing effect is improved on the premise of ensuring the printing speed.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
