See also Fig. 9, Fig. 9 is the sequential chart of ink-ribbon positioning system the 6th embodiment of the present invention.The Lights section of the present invention can also be replaced by the fluorescent tube of two identical colors.Embodiment shown in Figure 9 uses identical colour band 42 with the ink-ribbon positioning system of Fig. 2, but replaces green 62 and red light source 64 with the first white fluorescent tube 112 and the second white fluorescent tube 114.When having only a white fluorescent tube to be unlocked is first illumination, is second illumination when two white fluorescent tubes all are unlocked.It is high potential that the white light of first illumination can make the sensing voltage interpretation of sensor 66 during by yellow look frame 46, but during by the blue look frame 50 of aubergine 48 and cyanogen owing to have only less energy to penetrate, the sensing voltage of sensor 66 is a low-voltage.The white light of second illumination is by yellow 46 and can to make the sensing voltage interpretation of sensor 66 during aubergine look frame 48 be high voltage, but during by the blue look frame 50 of cyanogen owing to have only less energy to penetrate, the sensing voltage of sensor 66 is a low-voltage.So but programming identification sequential is as follows:
1. open the first white fluorescent tube 112, the sensing voltage that detecting sensor 66 produces.Transmission colour band 42 is jumped to high potential by electronegative potential until the sensing voltage that sensor 66 produces, and the time is represented with t61 at this moment, captures the signal of this voltage transitions signal as the yellow look frame 46 of colour band 42 arrival, finishes initial work.
2. when colour band 42 transferred aubergine look frame 48 to by yellow look frame 46, because light is covered mostly, the sensing voltage of sensor 66 was reduced to electronegative potential.Capture this voltage transitions signal arrives aubergine look frame 48 as colour band 42 signal.The time of this moment is to be t62.
3. when the time is t63, open the second white fluorescent tube 106, allow the light intensity by colour band 42 be enough to make the sensing voltage of sensor 66 to become high potential by low-voltage.This moment, the sensing voltage of sensor 66 was a high potential.Because interpretation device 68 knows that it is that change by light source is caused but not caused by the conversion look frame of colour band that this sensing voltage changes, so interpretation device 68 can not regarded the change of this voltage as the signal that the look frame is changed by mistake.
4. when colour band 42 changed into cyanogen blueness look frame 50 by aubergine look frame 48, the sensing voltage of sensor 66 became electronegative potential by high potential once more.Capture this voltage transitions signal arrives the blue look frame 46 of cyanogen as colour band 42 signal.The time of this moment is to be t64.
5. when the time is t65, close the first white fluorescent tube 104, the sensing voltage of sensor 66 still is an electronegative potential.
6. when colour band 42 was transferred to yellow look frame 46 by the blue look frame 50 of cyanogen, sensor 66 transferred high potential to by electronegative potential again.Capture this voltage transitions signal arrives yellow look frame 46 as colour band 42 signal.The time of this moment is to be t66.
7. finish one and take turns identification work, circulation gets final product in regular turn afterwards.
Above-mentioned the 5th embodiment illustrates as an example with two white fluorescent tubes 112,114, in fact as long as each color light source that has more than two kinds of different illumination all can reach identical purpose.For example use the red light source that to adjust illumination, as long as this red light source can pass through yellow look frame 46 than low-light (level) the time, but can't pass through the blue look frame 50 of aubergine 48 and cyanogen, and when higher illuminance, can get final product but can't pass through cyanogen blueness look frame 50 by yellow 46 and aubergine look frame 48.
The present invention is in above-mentioned shown embodiment, its sensor and light source are arranged at the not homonymy of colour band, in fact sensor and light source also can be arranged at the same side of colour band, as long as install the device of speculum and so on additional at the opposite side of colour band, just can make from the light penetration of light source and cross colour band and via after the mirror reflects, produce sensing voltage by the sensor sensing, all the other are then all disclosed identical with the embodiment of the invention.Again, in the foregoing description, colour band 42 is arranged in the ribbon cartridge, however the also inessential device of ribbon cartridge, and it is the look preface printer use of directly ribbon rooler being packed into that there is other products the market.
Compared to known ink-ribbon positioning system, ink-ribbon positioning system of the present invention can only utilize one group of sensor, thereby the part of look preface printer of the present invention is reduced, and production cost is minimized.Yet need to prove, spirit of the present invention is by send the purpose that first light, second light reach frame of all kinds position on the identification colour band respectively in different time points, the people in the industry is certainly according to instruction of the present invention, adopt the sensor of a greater number to reach same purpose, state clearly hereby.
The above only is preferred embodiment of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to the covering scope of patent of the present invention.
