The specific embodiment
For making advantages and features of the invention clearer, the embodiment that develops simultaneously with reference to the accompanying drawings is further described the present invention.
What prior art adopted is plastics grating chi, and read head utilizes the optical transmission principle to read signal, and the present invention adopts the metal grating chi, and read head utilizes the reflection of light principle to read signal, 1 describes in detail by the following examples.
Embodiment 1, and the PRN device that a kind of output resolution ratio is adjustable, this PRN device comprise metal grating chi 21, read head 22, frame 23, lead 24, lead 27, decoder 25 and adjustable frequency divider 26.Fig. 2 is a device mounting structure schematic diagram.Among Fig. 2, a plane of metal grating chi 21 be close to frame 23 and be fixed on frame 23 above, read head 22 is positioned at the another side of the metal grating chi 21 relative with frame 23.The signal that read head 22 is read by lead 24 outputs to adjustable frequency divider 26, the signal of 26 pairs of inputs of adjustable frequency divider carries out frequency division according to the divide ratio that the user selects, output to decoder 25 by lead 27 then, the signal of 25 pairs of adjustable frequency dividers of decoder, 26 outputs is decoded and is exported.Decode pulses shower nozzle of every output is finished once and is sprayed.
Tiny scale is arranged on the metal grating chi, and the precision of metal grating chi can reach 1um, also is 25400dpi, is higher than the 200dpi of plastics grating chi far away.The emitter of read head is transmitted into the delineation face of metal grating chi to light, reflects light in the read head by the grating ruling face then.So just the detection faces at read head produces pumping signal, obtains reliable high-frequency square wave.
This mounting means makes that the location association of grating chi and read head is littler, must be in the middle of read head unlike plastics grating chi, otherwise signal will be unreliable.By Fig. 2 also as can be seen, the one side of metal grating chi 21 is close to frame 23 and is fixed in the above, and is very reliable, so read head 22 can have higher movement velocity to read signal quickly.Generally 5m/s can be reached, therefore, print speed can be improved greatly.Generally, print speed and print resolution are the indexs of a contradiction, and the technical program allows the user can obtain higher print speed when obtaining higher output resolution ratio.
Unlike the prior art be that the present invention at first carries out frequency division by frequency divider before the signal of read head output is decoded, and the divide ratio of frequency divider is adjustable, different divide ratios is set can obtains different output resolution ratios.Such as, 2 frequency divisions can obtain 12700dpi, and 3 frequency divisions can obtain 8467dpi ... 20 frequency divisions can obtain 1270dpi, and 30 frequency divisions can obtain 847dpi ... when 256 frequency divisions, the output resolution ratio that obtains is about 99dpi.Certainly bigger divide ratio can also be set, when not excessive divide ratio is bigger, resolution ratio can be lower, daily use to people does not have bigger meaning, therefore, can select maximum divide ratio is that the adjustable frequency divider of 256 frequency divisions at first carries out frequency division to the signal of read head output, sends into decoder behind the frequency division and decodes, thereby obtain needed output resolution ratio.As shown in Figure 4, corresponding relation for output print number of times behind different divide ratios and the decoder decode, among the figure, each downward arrow is represented 1 injection of shower nozzle, as seen only finish 1 injection during 256 frequency divisions, 128 frequency divisions are then finished 2 injections, and 64 frequency divisions are finished 4 injections, and 32 frequency divisions are finished 8 injections.Like this, along with divide ratio from 1 to 256 changes, output resolution ratio just can be realized from 25400dpi to 99dpi adjustable continuously.
Certainly, the divide ratio of selecting to have different adjustable intervals can be set as required, coefficient also can be discontinuous, be odd number or be even number as divide ratio, or a fixing figure blank is arranged, or the like.
Wherein, adjustable frequency divider can integrate with decoder.
On embodiment 1 basis, do further to optimize, can obtain how different resolution ratio, describe for embodiment 2.
Embodiment 2, the PRN device that a kind of output resolution ratio is adjustable, and as different from Example 1, this PRN device also comprises a frequency multiplier, is used for output again behind the signal frequency multiplication of decoder output, Clock Multiplier Factor can be 2 or 4.As when Clock Multiplier Factor is 2, still establishing employed metal grating chi precision is 1um, the pairing output resolution ratio in 100 frequency divisions decoding back is 254dpi under this precision, then through after 2 frequencys multiplication, actual output resolution ratio is 254dpi*2=508dpi, after 4 frequencys multiplication, actual output resolution ratio is 254dpi*4=1016dpi, equally, 200 frequency divisions again after 2 frequencys multiplication back output resolution ratio be 127dpi*2=254dpi, 256 frequency divisions again after 2 frequencys multiplication output resolution ratio be 99dpi*2=198dpi, so just can obtain the continuous adjustable extent of output resolution ratio from 198dpi to 50800dpi.
Same principle, when Clock Multiplier Factor is 4, but at divide ratio from 1 to 256 timing, pairing output resolution ratio adjustable extent is 400dpi to 101600dpi.
As seen,, can improve the output resolution ratio of print image greatly, also obtain bigger adjustable range simultaneously by frequency multiplication.
But, the frequency multiplication number of times is not unlimited, usually only carry out 2 frequencys multiplication or 4 frequencys multiplication, because Clock Multiplier Factor is the available accuracy of conference reduction output resolution ratio too, when Clock Multiplier Factor is too big, may make output resolution ratio can't satisfy due required precision, therefore, the Clock Multiplier Factor of suggestion frequency multiplier is made as 2 and/or 4.
In addition, the user can select a suitable output resolution ratio adjustable range according to the needs of oneself.For example, the general user may use less than the extra high resolution ratio of output resolution ratio, and such as surpassing 12700dpi, at this moment the user can select the adjustable range of 100dpi to 12700dpi, do not having frequency multiplier to carry out under the situation of frequency multiplication, its corresponding divide ratio can be set to 2 to 254.
As required, adjustable frequency divider, decoder can be integrated, perhaps with decoder and frequency multiplier integrates or adjustable frequency divider, decoder, frequency multiplier three are integrated.
More than the adjustable PRN device of a kind of output resolution ratio provided by the present invention is described in detail, used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
