Abstract
The invention relates to an image forming method, which detects carbon powder mark pattern for colour difference emendation to emend colour difference and overlaps pattern with plural colours to form coloured pattern. The method comprises steps: at first, performing discrimination about whether the colour difference emendation has been continuously succeeded for certain times; if continuously succeeded, forming a carbon powder pattern for setting the width of emended carbon powder mark pattern to be thinner than an initial value from the beginning of next time; then storing the width of thinned pattern as the setting value to be used next time; then ending the treatment. As a result, if the colour different emendation control of next time has succeeded for certain times, much thinner pattern is formed. On the other hand, even if the colour difference emendation only fails once, the pattern width is set to be the one that is thicker than the initial value; and the emendation is carried out again to thicken the pattern width gradually until it succeeds.

Preferred forms of the present invention
Below with reference to the description of drawings embodiments of the present invention.
Fig. 1 is the generalized schematic that the coloured image of expression one embodiment of the present of invention forms the major part of device.In this figure, coloured image forms device and is made of systems control division 1, ROM 2, involatile RAM 3, LD write circuit 4, carbon dust mark (TM) sensor 5, transcription band 6 and image-forming block 10.Image-forming block for example is in-line colour imaging parts, have photoreceptor 10Y, 10C, 10M, 10K (following unify to represent) with symbol 10, be arranged on each photoreceptor periphery and figure in do not have charged elements, visualization unit, transcription unit, the cleaning unit of expression and remove electric unit etc.
The Data Detection that systems control division 1 is used to carry out about based on TM sensor 5 is handled and achromatic.ROM 2 is used for stored programme, and involatile RAM 3 is used to store data that are used for achromatic etc.LD write circuit 4 is the circuit that are used to produce the laser that shines photoreceptor 10.TM sensor 5 is the light reflection sensors that are used to detect the distance between the carbon dust indicia patterns.In the structure of Fig. 1, charged elements makes the surface charging of each photoreceptor 10, and the laser that LD write circuit 4 is not represented in the surface emitting figure of each charged photoreceptor 10 carries out light and writes, to form sub-image.Sub-image carries out the carbon dust video picture by visualization unit according to shades of colour, the carbon dust picture of video pictureization by transcription to transcription band 6, to form coloured image.
Fig. 2 is the view that the carbon dust indicia patterns after the structure of Fig. 1 carry out phenomenonization is used in expression.Here, the order of describing the carbon dust indicia patterns is yellow (Y), black (K), blue or green (C), pinkish red (M).At first, shown in Fig. 2 (1), during achromatic, describe with the predefined width that is used for the carbon dust indicia patterns of achromatic.TM sensor 5 reads the width of this setting, and systems control division 1 carries out position deviation revisal control according to the output of TM sensor 5.Position deviation revisal control itself is prior art as disclosed in the above-mentioned example, so it is not illustrated especially here.After achromatic is controlled successfully certain number of times,, shown in Fig. 2 (2), describe pattern with thin other width of level again since next time.In addition, if the achromatic control failure of carrying out with the pattern of Fig. 2 (1) shown in Fig. 2 (3), is then described pattern with thick other width of level again, and is carried out revisal control.Here said achromatic is controlled successfully certain number of times, be meant that reading the carbon dust indicia patterns carries out position deviation revisal control after, this position deviation revisal amount is not needed to have carried out revisal again during as the initial value revisal.
" first embodiment "
Fig. 3 is the process flow diagram of the processing sequence of expression first embodiment.In this embodiment, according to the success of achromatic control or the width of the change pattern shown in Figure 2 of failing.This control is carried out by systems control division 1.
In Fig. 3, handle beginning back (step 101), at first carry out achromatic whether continuously success the differentiation (step 102) of certain number of times.If success (step 102-Yes) continuously, since next time, the width setup that then forms the carbon dust indicia patterns that will be used for revisal is the carbon dust pattern (step 103) thinner than initial value, store the pattern width that subtracted carefully then using (step 104) as setting value, end process since next time.Like this, if the also successful continuously certain number of times of the achromatic of next time control then forms thin again pattern.
On the other hand, even the achromatic of step 102 is only failed once (step 102-No), also pattern width is set at than initial value also thick (step 105), and carry out revisal (step 106) once more, carry out this processing repeatedly, gradually with the pattern width overstriking, till success.
In other words, in the present embodiment, the carbon dust indicia patterns that will be used for achromatic is depicted in the transcription band, when obtaining the data that are used for revisal and carry out achromatic, the pattern width of sub scanning direction that will be used for the carbon dust indicia patterns of achromatic subtracts carefully (execution in step 102 → 103 → 104 repeatedly, and it is reduced carefully gradually) as much as possible.At this moment, if the pattern width of sub scanning direction has been controlled successfully number of times necessarily with the achromatic that width was carried out of a certain setting, then describe the pattern width (step 103) of sub scanning direction with thin other width of level again, if the pattern width of sub scanning direction is with the achromatic that width was carried out of a certain setting control failure, then describe the pattern width (step 105) of sub scanning direction with thick other width of level again.
Like this, if achromatic is controlled successfully certain number of times, the carbon dust indicia patterns that is used for achromatic will be tapered, and just can suppress to be used for to describe to be used for the carbon dust consumption of the carbon dust indicia patterns of achromatic.Therefore, by present embodiment as can be known, because can subtract the pattern width of the sub scanning direction of the carbon dust indicia patterns that carefully is used for achromatic as much as possible, so can suppress to be used for to describe to be used for the consumption of carbon dust of the carbon dust indicia patterns of achromatic.
In addition, if achromatic is controlled successfully certain number of times, because describe the pattern width of sub scanning direction, so can suppress to be used for to describe to be used for the consumption of carbon dust of the carbon dust indicia patterns of achromatic with thin other width of level again.
In addition, if achromatic control failure, because would describe the pattern width of sub scanning direction, so during revisal control failure, the pattern width overstriking can be carried out revisal control once more with thick other width of level again.
" second embodiment "
Fig. 4 is the process flow diagram of the processing sequence of expression second embodiment.In this embodiment, when obtaining the data that are used for revisal and carrying out achromatic, the number of times of a certain setting if the achromatic control that the pattern width of sub scanning direction is carried out with a certain setting width has been failed, then with the lower limit width of this pattern width as the carbon dust indicia patterns width that is used for achromatic, afterwards, just no longer describe the following carbon dust indicia patterns of this lower limit width.
In other words, in Fig. 4, beginning back (step 111) is handled in revisal, the pattern width of setting is made as L, if control failure (step 112-No) with the achromatic that pattern width L is carried out, then the frequency of failure of being carried out with pattern width L is added up (step 113), if the number of times of failure is more than or equal to the number of times of setting (step 114), then pattern width L is made as lower limit (step 115), afterwards, to just no longer carrying out revisal and end process (step 117) below the pattern width L.
Like this, the number of times of a certain setting if the achromatic control that the pattern width of sub scanning direction is carried out with a certain setting width has been failed, then with the lower limit width of this pattern width as the carbon dust indicia patterns width that is used for achromatic, afterwards, this carbon dust indicia patterns below lower limit width has not just been described, therefore, can achromatic not controlled with the higher pattern width of possibility of failure.
" the 3rd embodiment "
Fig. 5 is the process flow diagram of the processing sequence of expression the 3rd embodiment.In this embodiment, when obtaining the data that are used for revisal and carrying out achromatic, if achromatic is controlled more than the ratio of a certain setting of having failed, then with the lower limit width of this pattern width as the carbon dust indicia patterns width that is used for achromatic, afterwards, this carbon dust indicia patterns below lower limit width is not then described.
In other words, in Fig. 5, beginning back (step 121) is handled in revisal, the pattern width of setting is made as L, if control failure (step 122-No) with the achromatic that pattern width L is carried out, then after having carried out the revisal of setting more than n time, calculate the ratio (step 123) of the failure of being carried out with pattern width L, if the ratio of failure is more than or equal to the ratio of setting (step 124), then pattern width L is made as lower limit (step 125), afterwards, then do not carry out revisal (step 126) with the following width of pattern width L, and end process (step 127).
Like this, if the achromatic that the pattern width of sub scanning direction is carried out with a certain setting width is controlled more than the ratio of a certain setting of having failed, then with the lower limit width of this pattern width as the carbon dust indicia patterns width that is used for achromatic, afterwards, this carbon dust indicia patterns below lower limit width is not then described, therefore, can achromatic not controlled with the higher pattern width of possibility of failure.
" the 4th embodiment "
Fig. 6 is the process flow diagram of the processing sequence of expression the 4th embodiment.In this embodiment, when obtaining the data that are used for revisal and carrying out achromatic, when the pattern width of sub scanning direction is failed with the achromatic that width the was carried out control of a certain setting, then describe the pattern width of sub scanning direction with thick other width of level again, yet, owing to set higher limit in advance, so, even the width that causes pattern owing to the failure of achromatic is by rank chap gradually, but when reaching higher limit, also be to adopt higher limit to describe pattern width.
In other words, in Fig. 6, beginning back (step 131) is handled in revisal, the pattern width of setting is made as L, when the achromatic control of being carried out with pattern width L is failed (step 132-No), although pattern width is made as thick other M (step 133) of a level again, if M has surpassed the higher limit of setting (step 134-Yes), then pattern width is continued to be made as L (step 135), and carry out revisal control (step 136), end process (step 137) once more with L.If M does not surpass the higher limit of setting (step 134-No), then adopt pattern width M to carry out revisal control (step 137) once more, and end process (step 137).
Like this, when the pattern width of sub scanning direction is failed with the achromatic that width the was carried out control of a certain setting, then the pattern width of sub scanning direction is described with thick other width of level again, yet, owing to set higher limit in advance, so, even owing to the achromatic failure causes pattern width by rank chap gradually, but, when reaching higher limit, because be to adopt higher limit to describe pattern width, so, be used for the unrestrictedly chap of width of the pattern of achromatic control.In addition, even at this moment, because prerequisite be under the condition that can carry out the position deviation revisal, pattern width is set at thin as much as possible, so, even pattern width than initial value thick also can with its thin be constant to carrying out this point of minimum widith that the position deviation revisal handles.
" the 5th embodiment "
Fig. 7 is the process flow diagram of the processing sequence of expression the 5th embodiment.In this embodiment, although the pattern width of sub scanning direction has reached higher limit,, then stop achromatic afterwards if achromatic is failed continuously, suppress the carbon dust consumption processing or, carry out machine is set at the processing of fault.
In other words, in Fig. 7, beginning back (step 141) is handled in revisal, arrived upper limit value M (step 142) if be used for the pattern width of achromatic control, and from then on, achromatic is controlled the number of times of setting (n time) (step 143-Yes) of having failed continuously, in addition, later setting is to stop revisal control (step 144-revisal stops) if fail continuously for n time, correspondence when failing so continuously is to stop achromatic control (step 145), suppress carbon dust consumption (step 146), finish revisal and handle (step 148).On the other hand, if the correspondence when failing continuously is the setting (step 144) of mechanical disorder, then machine is set at fault (step 147) and end process (step 148).
Like this, although the pattern width of sub scanning direction has arrived higher limit, when achromatic is failed continuously, because be set or can be set at, stop achromatic afterwards, suppress the carbon dust consumption figure processing and, machine is set at fault processing both one of, so, just can suppress to describe to be used for the consumption of carbon dust of the carbon dust indicia patterns of achromatic.
" the 6th embodiment "
Fig. 8 is the key diagram of formation state of the pattern of expression the 6th embodiment.In this embodiment, when when determining initialization, being used for the initial value of width of carbon dust indicia patterns of revisal, beginning to describe the carbon dust indicia patterns from higher limit, and only pattern width is set at initial value with the tapered pattern of certain width.
In Fig. 8, when when determining initialization, being used for the initial value of carbon dust indicia patterns width of achromatic control, as shown in the figure, begin to describe tapered pattern from versicolor upper limit value M, therefrom try to achieve the pattern width that to discern, still, because the minimum widith that can discern is as initial value, the possibility of achromatic control failure is higher, so, make its tool leave some leeway.
The processing sequence of this moment is represented in the process flow diagram of Fig. 9.In this figure, this handles beginning back (step 151), during initialization when arrival, during the transcription tape swap, during the photoreceptor exchange etc. (step 152), describe to begin with the tapered carbon dust indicia patterns of certain width (step 153) pattern width (step 154) that uses TM sensor 5 to obtain then can to discern from upper limit value M.In addition, it is back as initial value (step 155) that it is suitably allowed some leeway, and this initial value is kept among the involatile RAM (step 156) end process.
Like this, when when determining initialization, being used for the initial value of carbon dust indicia patterns width of revisal, begin to describe the carbon dust indicia patterns from higher limit because adopt with the tapered pattern of certain width, with only pattern width (do not make achromatic failure width) as initial value, so, be used for the original width of the carbon dust indicia patterns width of achromatic control in the time of can determining initialization.In addition, because described initialization is to implement when arrival, during the transcription tape swap, during the photoreceptor exchange, shown in, can set the time of carrying out initialization process exactly.
In addition, when obtaining the data that are used for revisal and carry out achromatic, for the consumption of the carbon dust of the carbon dust indicia patterns that suppresses to describe to be used for achromatic, be necessary the pattern width that is used for the optimum on the sub scanning direction of carbon dust indicia patterns of achromatic is preserved as data.Because have in order to preserve the non-volatile memory of data, so can when being in power-off or under the state when energy-conservation, preserve data.
Figure 10 is the key diagram of the meaning of the revisal of expression when being used to illustrate combination and implementing the described achromatic control of first to the 6th embodiment.Here expression is the variable condition of the width of carbon dust indicia patterns.At first, determine initial set value (being expressed as " initial value " among the figure), if continuously success (being 5 times in the example among the figure) is then described pattern width with a thin rank again, if failure, then with the pattern width overstriking.If, then be set at lower limit with the achromatic that a certain pattern width was carried out the failed number of times set or certain ratio (serve as failure 4 times in the example among the figure), afterwards, even the width below this lower limit is not set in success continuously yet.
In addition and since carbon transducer through the time deterioration etc. when causing pattern width chap at any time, finally might reach higher limit, at this moment, even failure does not make its thick higher limit of crossing yet.But, if the revisal of being carried out with higher limit control failure (being 5 times in the example among the figure) continuously, then stop afterwards achromatic or, carry out the processing of mechanical disorder.
Figure 11 is the synoptic diagram of the formation state of expression carbon dust indicia patterns.In above-mentioned first to the 6th embodiment, narrate for the processing that each color is common, still, do not need to use all identical pattern for four kinds of colors yet.According to actual operating position, the width difference of the employed carbon dust indicia patterns of shades of colour.So,, in each device, also have the difference of versicolor deviation even use as initial value.Therefore, the pattern width that is used for achromatic control begins just to set with all different width of shades of colour from the stage of setting initial value as shown in figure 11, and pattern width afterwards also changes independently by shades of colour.
Like this, be to set because be used for the pattern width of sub scanning direction of the carbon dust indicia patterns of achromatic by black, yellow, pinkish red, each blue or green color, so, just can suppress to describe to be used for the carbon dust consumption of the carbon dust indicia patterns of revisal by each color.
The carbon dust indicia patterns for example is arranged on three positions of front side, central authorities, rear side mostly.Figure 12 represents that the A row, the B that are provided with front side, central authorities, rear side are listed as, the synoptic diagram of the example of the carbon dust indicia patterns of three row of C row.TM sensor 5 is arranged on A, B, C respectively lists, and is listed as and reads the carbon dust pattern by each.At this moment, certainly, the initial value of the pattern width of each pattern of above-mentioned A row, B row, C row is all inequality, and in addition, pattern width also changes independently by shades of colour, each row.
In addition, the setting that is used for the pattern width on the sub scanning direction of carbon dust indicia patterns of achromatic adopts the quantity of sweep trace to manage.This management is responsible for by systems control division 1.
Like this, after setting is used for the width of carbon dust indicia patterns of achromatic, when carrying out achromatic, although versicolor pattern width is different, but, as shown in figure 13, irrelevant with the width of pattern, from pattern describe begin till the describing of the pattern of next color, all to maintain a certain distance.Like this, just can make the time of achromatic control keep certain.
In addition, the processing sequence of the process flow diagram among first to the 7th embodiment be kept among the ROM2 or, preserve in the drawings not in the hard disk of expression, and carry out by the CPU of systems control division 1.In addition, program also can be downloaded and use via external memories such as FD, CD-ROM, card-type storage device, internet or means of communication.
The present invention is not limited to above-mentioned specific embodiment, only otherwise break away from the scope of claims, also can adopt other versions to replace, but those versions still belongs to scope involved in the present invention.
