Specific implementation mode
Such as Fig. 4, it is 6 groups of 24 needle that print head, which goes out needle arrangement mode, specially：It is 1,2,3 ... 24 that 24 needles, which are sequentially numbered,
Distribution mode is：24 rows laterally are accounted for, often row has a needle, and the spacing between adjacent needles is all 1P, i.e., between 1 and 2, between 2 and 3
Spacing be 1P, 1 and 24 23 P of spacing, if 1P be 1/180 inch；Longitudinal direction accounts for 6 row, and first row includes two needles, secondary series packet
Four needles are included, third row include six needles, and the 4th row include six needles, and the 5th row include four needles, and the 6th row include two needles, and each row are at one
Group, first row i.e. first group.
As in Figures 3 and 4,11,13 be one group, 7,9,15,17 be one group, 1,3,5,19,21,23 be one group, 2,4,6,20,
22,24 be one group, and 8,10,16,18 be one group, and 12,14 be one group, amounts to 6 groups of needles, and same group of needle is on same vertical line,
I.e. same group of needle is same row.
Such as Fig. 3, on horizontal direction, on the basis of first group, second group of spacing to the 6th group of first group of distance is respectively
The spacing of L21, L22, L23, L24, L25, the second Ariadne of the first row distance are L26.
Every group of needle is as follows relative to the spacing of first group of needle：L21=(1+6/8) P, L22=(5+4/8) P, L23=(12+5/
8) P, L24=(16+3/8) P, L25=(18+1/8) P, L26=1P*23.
To go out the needle period constant for 24 needle, 6 row print head with respect to the background art for print head of the present invention, is arranged based on above-mentioned needle
The print head of row mode, when carrying out 180dpi resolution ratio letterings, the spacing and 1/ that is arranged to the 6th column distance the 1st due to secondary series
180 inches be not integral multiple relationship, go out the needle period it is constant under the premise of, need to secondary series to the 6th row needle into line delay
Go out needle, ensures that print needle goes out needle without lettering dislocation occurs going out pin position.Assuming that it is T to go out the needle period, the needle that goes out of 6 row needles prolongs
When the time it is as follows：First row is no-delay；Secondary series delay 2T/8；Third row delay 4T/8；4th row delay 3T/8；5th row prolong
When 5T/8；6th row delay 7T/8.
By taking Fig. 4 as an example, when print head moves from left to right lettering, and first row is in out pin position, it can calculate
Go out secondary series to the 6th column distance it is next go out pin position distance be respectively (2/8) P, (4/8) P, (3/8) P, (5/8) P, (7/
8)P.Known one goes out needle cycle T, and print head moves the distance of 1P.It, only need to be by secondary series to the so when originally going out the needle period
Six row needles are delayed 2T/8,4T/8,3T/8,5T/8,7T/8 respectively, you can so that this 5 groups of needles go out needle going out pin position, without sending out
Raw lettering dislocation.Due to the processing of delay, 6 row needles can only point out needle in same period different time so that 6 row needles are staggered alternating
Go out needle, avoid multiple row needle while going out needle, to reduce the peak noise of print needle operation.
If Fig. 5 is when 7,9,15,17 are in out pin position for one group of print needle, remaining 5 groups of needles are not going out needle position
It sets, is respectively at the position for separating out pin position (6/8) P, (2/8) P, (1/8) P, (3/8) P, (5/8) P, you can be interpreted as 7,
9,15,17 for one group of needle when going out needle, and the possibility that synchronization goes out needle is all not present in other 5 groups of needles.And so on, when each
A group when be respectively at out pin position, other five groups are not located in out pin position.Which can be interpreted as regardless of group needle
When going out needle, the possibility that synchronization goes out needle is all not present in other 5 groups of needles.So the print head of the arrangement mode can be with
Accomplish that every group of needle is staggered and alternately go out needle, the case where avoiding the occurrence of multigroup needle while going out needle, it is more evenly dispersed to go out needle, to reduce
The noise of print head operation.
Embodiment is merely illustrative of the invention's technical idea, and cannot limit protection scope of the present invention with this, it is every according to
Technological thought proposed by the present invention, any change done on the basis of technical solution, each falls within the scope of the present invention.
