Description

A kind of environment-friendly type printhead goes out faller gill row method

Technical field:

The present invention is that a kind of environment-friendly type printhead goes out faller gill row method.Its main purpose is that the assurance printhead is realized low noise, low-power consumption, long-life under specific print speed.

Background technology:

Along with the development of China's PRN device, impact printer all is widely used in every field, and its environmental protection is printed and also praised highly by each row, and the present invention is exactly the method that realizes that environmental protection is printed.

Application number: 98115516.2, at single carriage a plurality of printheads are housed, printhead have by impacting recording medium form a plurality of print needles of matrix of printed dots, selectively make a plurality of print needle drive units that the vertically displacement of each print needle drives, each print needle drive unit is contained in integratedly wherein printhead housing, is installed on the printhead housing and the guiding print needle is arranged in print needle guiding elements on the assigned position, be characterized in, make the printhead housing of each printhead form one with common member.The present invention has realized can stablizing and keeping accurately printing carriage apparatus and the printing equipment of print needle relative position.

CN99107587.0 provides a kind of great-jump-forward (sketch) printer drive method for the row dot printer, and the print needle that its printhead group is arranged by zigzag consists of.In the zigzag print needle is arranged, repeat to arrange the print needle group in the direction perpendicular to paper feed direction, it comprises L respectively at the 1st print needle that execution point is printed to the L dot printing row.During each one-stroke of printhead group, from the print needle group, specify one or more print needles in one-stroke, to drive the execution point printing by the drive circuit of row dot printer.The method can be improved printhead group characteristic, and can alleviate the drive circuit load and reduce interference level.

CN98109203.9 has the dot matrix print head of a print needle guiding parts, comprise: first row print needle pilot hole, the first round has the center of circle that is arranged in accordingly on first vertical straight line, and along described first vertical straight line each other at a distance of the fixed range of a pitch; $ second row print needle pilot hole, the second round have the center of circle that is arranged in accordingly on the second vertical straight line that is parallel to first vertical straight line, and these centers of circle along described second vertical straight line each other at a distance of the fixed range of described pitch.The center of circle of each the second round of $ is arranged on the corresponding laterally straight line, this horizontal straight line and first vertical straight line intersect with the equidistant point in two adjacent holes centers of circle of first row on.

The CN201110229351.6 impact printer, it possesses: printhead unit, it has makes print needle impact the contact history medium and the stylus head that prints and the scaffold that described stylus head is supported via ink ribbon; The path forms member, it forms the transport path of the described recording medium on the print position of described stylus head, wherein, be provided with the first butt group at described scaffold, this first butt group has that near described stylus head position and described path form the member butt and at least three contacts of location of carrying out forming with respect to described path the print needle projected direction of member.

The printhead of existing stylus printer is uniform design, yet goes out faller gill row method there are no the environment-friendly type printhead, and the peak power of using the stylus printer seal is minimum; Peak noise when using the stylus printer seal is minimum.Print needle deflection in printhead is arranged is minimum, thereby guarantees that the print needle life-span is longer.

Summary of the invention:

The present invention seeks to, propose a kind of effectively laterally (row) and vertical (row) arranged with interval method, and for the environment-friendly type printhead goes out faller gill row method, the peak power of using the stylus printer seal is minimum; Peak noise when using the stylus printer seal is minimum.Especially its row are apart from having adopted more rational computational methods with array pitch.

Technical scheme of the present invention is: a kind of environment-friendly type printhead goes out faller gill row method, these aligning method 24 pin printheads: vertically have 12 row, every row 2 pins at least, laterally have 24 rows at least, every row's 1 pin; 48 pin printheads vertically are 16 row, every row 2 to 4 pins, horizontal 24 rows, every row 2 pins.Especially its row are apart from having adopted more rational spacing with array pitch.
