The specific embodiment
When on paper, writing data in order to solve general thermal printer, influence the print phenomenon of quality of thermal printer because hot write head heating is uneven, the present invention discloses a kind of hot write head heating means that are applied to thermal printer.In the method; The mode of heating of hot write head be not like prior art said as in a continuous manner to hot write head heating heat of cooling write head in a continuous manner again; But hot write head is heated and cooling with minute mode of multistage time; And in the process that writes the single file data, to the heating of hot write head be enough to total time make it reach a target color range.Thus, hot write head can continue to maintain more than the specific degrees (a for example specified temp) to the heating of paper, and can not make hot write head write the uneven phenomenon of being heated in the process of single file data.
See also Fig. 1, its for to the hot write head heating of thermal printer when carrying out write operation, the lasting mode of heating of implementing prior art and the present invention compare sketch map with the sequential of the hot write head heating means that the segmentation mode of heating is implemented.As shown in Figure 1; The write color range value range of case hot sublimation printer is 0 to 256; And the predetermined at present target color range that writes is 128; Then when hot write head being heated, make when hot write head carries out write operation to a certain row on the paper with the continuous mode of heating shown in the prior art; Hot write head can be continued heating TH128 one period heat time heating time earlier, and continued to stop to heat one section cool time TC128, and accomplish the single file write operation; The write time that wherein heat time heating time TH128 and cool time, TC128 added stack up is T, and write time T needed time when promptly representing color range with hot write head to be heated to 256 (that is the highest color ranges) and to be accomplished the single file write operation by 0 (that is a minimum color range).And in the disclosed hot write head heating means of implementing with segmented mode of the present invention; Be with heat time heating time TH128 be divided into eight sections isometric or non-fully isometric Band1 heat time heating time, Band2, Band3, Band4, Band5, Band6, Band7, Band8; And assign not to hot write head heating eight sections corresponding cool time of BC1, BC2, BC3, BC4, BC5, BC6, BC7, BC8 after the Band1-Band8 separately in these heat time heating times, wherein cool time BC1-BC8 the totalling time span equal the time span of TC128 cool time.Thus; What hot write head can repeat reaches 128 target color range value to be heated the mode that and then is not heated one period cool time after one period heat time heating time (that is with minute multistage time heating and divide the mode of multistage time cooling), makes paper when hot write head can not take place like continuous heating be heated too to concentrate and the print situation of quality of influence.
As stated; Time span between the heat time heating time Band1-Band8 can be incomplete same; And can be in a preferred embodiment of the present invention according to least unit heat time heating time, and the thermal printer target color range desiring to write and the color range difference between its writeable minimum color range time span that decides Band1-Band8 heat time heating time, its deciding means is narrated as follows.In this diagram and the data of giving an example of continuing to use Fig. 1, at first least unit S heat time heating time can determine as follows:
Wherein K is that color range between the writeable the highest color range of thermal printer and the minimum color range is poor, and when this value of high color range be 256, the value of this minimum color range is 0 o'clock, the value of K is 256.Then, decide the time span of Band1-Band8 heat time heating time with formula (2), (3), (4), formula (2), (3), (4) are represented as follows:
C％N＝R，0≤R＜N (3)；
Band
i＝S*(Q+r)，1≤i≤N (4)；
C represents the color range between target color range and the minimum color range (for example being 0) poor.N is the number of Band1-Band8 heat time heating time, is 8 in this its value, however the value of N can set arbitrarily according to different needs in other embodiments of the invention, and be not restricted to shown in Figure 1.Q is the quotient that color range difference C obtains divided by number N, and R is the remainder that color range difference C obtains divided by number N.R is a parameter, and its value can be 0 or 1.
Data according to above hypothesis; And the predetermined color range value of hypothesis is 134; Then the value of C is 134, and the value of Q is 134%8=6 for the value of
R.At this moment; According to a preferred embodiment of the invention; For make Band1-Band8 heat time heating time length each other as much as possible mean deviation reach the purpose that is heated to predetermined color range value 134 simultaneously; Can find out six heat time heating times (that is value of remainder R) the Band1-Band8 arbitrarily from heat time heating time, and the parameter r of these six heat time heating times is set at 1, the parameter r of all the other two heat time heating times is set at 0; Thus, the time span that has six heat time heating times heat time heating time among the Band1-Band8 is S* (Q+r)=S* (Q+1)=S* (16+1)=17S, and the time span of two other heat time heating time is S* (Q+r)=S* (Q+0)=S* (16+0)=16S.In addition, when the value of color range difference C just in time divided exactly the value in number N, the value of remainder R was 0, and then the value with the parameter r that decides Band1-Band8 heat time heating time is all 0, that is heat time heating time Band1-Band8 length all equal.
Observing above-mentioned example can know; Though the time span between the heat time heating time Band1-Band8 can be non-equal fully; But maximum disparity length is merely least unit S heat time heating time, therefore still can be issued to the purpose of even heating in the certain condition that is heated to predetermined color range of hot write head.
The present invention discloses a kind of hot write head heating means of thermal printer; Through with the heating of minute multistage time and divide the mode of multistage time cooling that hot write head heat, to avoid taking place general thermal printer to have influence on the situation that writes quality continuously to hot write head heating and when cooling off.
The above is merely the preferred embodiments of the present invention, and all equalizations of doing according to claims of the present invention change and modify, and all should belong to covering scope of the present invention.
