Embodiment
Followingly specific embodiments of the invention are elaborated with reference to accompanying drawing.
First embodiment
Fig. 1 is the integrally-built synoptic diagram that shows an embodiment 1 that can use image processing system of the present invention.
The step of the transmission paper operation of the image processing system 1 that shows of key diagram 1 at first.
In image processing system 1, when paper-feed roll 3 when main body paper feed tray 2 outwards rotates, open from a stacker by the separating components (not being shown among the figure) in the main body paper feed tray 2 that isolated a piece of paper at first is transferred into registration roller 4 S.
Here, be main body paper feed tray 2 though Fig. 1 display image forms the paper feed unit of device 1, also the main body paper feeding cassette can be set in addition in the image processing system 1, the 2nd paper feeding cassette, hand difference formula paper feeding cassette.In this case, these when paper-feed roll 3 when these paper feeding cassettes outwards rotate, be transferred into registration roller 4 by the isolated a piece of paper of separating component separately.
When transmitting paper, if surpass certain predetermined value from the time that paper-feed roll 3 begins to turn to alignment sensor 4a energized, general judge not paper supply paperboard has taken place, this is that device is in not paper supply paperboard error condition.
Positioning clutch (not being shown among the figure) is installed in the registration roller 4, if paper-feed roll 3 is normally sent paper, when transmitting paper to registration roller 4, positioning clutch is closed in advance, make registration roller 4 be in not rotation status, therefore, when top of form is run into registration roller 4, when to a certain degree crooked occurring, promptly stop paper-feed roll 3.(make top of form run into registration roller 4, form crooked) like this, can to a certain degree revise the crooked of top of form.
Then, registration roller 4 and paper-feed roll 3 are rotated, restart to transmit paper to imaging portion.When transmitting paper, the position of top of form and imaging time are coincide, this can guarantee the precision of top of form print position.
The operating process of image processing system 1 when carrying out single face printing and duplex printing of present embodiment below is described respectively.
Usually, when single face was printed, the passage from each paper feeding cassette along direction of transfer D1 (transmission road) transmitted paper, or discharged paper.
When printing on the two sides, equally, passage (transmission road) along direction of transfer D1 transmits paper, and temporarily the fore-end of paper is delivered to the outside top (rather than all sending and discharge paper) of image processing system 1, rear end part is clamped by exit roller 18, in this state, paper is stopped, allow exit roller 18 backward rotation then, when printing reverse side along the channel transfer paper of direction of transfer D2 to the location division (be the parts of center formation with registration roller 4).Then, identical with the single face printing, discharge paper along the passage of direction of transfer D1.
By above operation, image processing system 1 can be realized the two sides printing.
The below operating process of image processing system 1 when printing continuously of explanation present embodiment.
When printing continuously, carry out secondary transfer roll 16 simultaneously and will be formed on the operation that image on the transfer belt 5 is transferred to operation and the image of one page under forming on the transfer belt 5 on the paper.
Afterwards, the image of each page forms (below be referred to as page or leaf at interval) at regular intervals.Since can not stop imaging portion, transfer belt 5, and the running of the imaging portion of secondary transfer roll 16 etc. be necessary that finishing paper in the page or leaf interval supplies with, and the front position of control paper overlaps with the picture position.
Yet, when beginning from paper feeding to change, might can't finish the paper feeding of a piece of paper down in page or leaf at interval and operate to the time interval that paper feeding is over.Therefore, carry out imaging earlier, in imaging page or leaf interval, finish paper feeding for needs, make the incompatible system that carries out transfer printing of paper and time kissing, change, surpass the imaging page or leaf be predetermined during interval time when the paper supply time, if be not expanded into as a page interval time, just can not realize continuous printing.

The below continuous paper supply operation of explanation present embodiment.
Fig. 3 is the process flow diagram that the paper supply of the image processing system 1 of demonstration present embodiment is operated.
As shown in Figure 3, in step S301, the CPU 101 of control image processing system 1 integrated operation determines that according to Fig. 4 the paper supply paperboard is not judged clocking value.This not the paper supply paperboard judge that the clocking value note makes B.
In step S302, CPU 101 determines the imaging page or leaf at interval according to Fig. 4.This imaging page or leaf length note is at interval made X.
In step S303, CPU 101 removes the value that paper-feed roll drives timer.This paper-feed roll drives the value note of timer and makes A.
In step S304, the paper-feed roll driving motor begins to rotate.
In step S305, paper-feed roll clutch coupling energized (ON).
In step S306, paper-feed roll drives timer and is activated.
In step S307, CPU 101 judges whether alignment sensor 4a (with reference to Fig. 1) is switched on power supply.
If the access failure power supply then enters step S308.If the on power supply then enters step S309.
In step S308, CPU 101 more not paper supply paperboard judges that clocking value B and paper-feed roll drive the size of the value A of timer.If A greater than B, then judges not paper supply paperboard has taken place, so stop paper supply.If A is not more than B, then return step S307.
In step S309, it is crooked to form the location.
In step S310, close the power supply (OFF) of paper-feed roll clutch coupling.
In step S311, the value that paper-feed roll is driven timer is added to the paper-feed roll accumulation driving count value of storing among the NVRAM 104 (Fig. 2).
In step S312, remove the value (A) that paper-feed roll drives timer.
In step S313, the paper-feed roll driving motor stops operating.
Has CPU101 judged whether that with registration roller 4 be the location division that constitutes, center time of paper feeding once more in step S314? if arrived the time of paper feeding once more, then entered step S315.
In step S315, the paper-feed roll driving motor begins to rotate.
In step S316, connect the power supply (ON) of paper-feed roll clutch coupling.
In step S317, connect the power supply (ON) of registration roller clutch coupling.
In step S318, start paper-feed roll and drive timer.
In step S319, after judging the paper rear end and following a piece of paper separates, CPU101 whether passed through certain hour α (this time, α was different because of device).If do not pass through this section period α as yet, then wait for, up to reaching time α always.If passed through time α, then enter step S320.
In step S320, close the power supply (OFF) of paper-feed roll clutch coupling.
In step S321, the value that paper-feed roll is driven timer is added to the paper-feed roll accumulation driving count value of storing among the NVRAM 104.
In step S322, remove the value (A) that paper-feed roll drives timer.
In step S323, CPU101 judges whether to transmit the request of a piece of paper down.If no, then finish the paper feeding operation, if α is arranged, then return step S304, repeat above operation.
The below above explanation of arrangement.Usually, driving paper-feed roll 3 does the time of paper feeding operation and can set through optimization in advance.Each paper feeding operation the accumulated value of driving time leave among the NVRAM104 (involatile RAM).
The unit of driving time can be second.If use the second counter of 4 bytes, i.e. count enable is much larger than the value of time device lifetime.
Behind the power supply (ON) of connecting the paper-feed roll clutch coupling, alignment sensor is energized also, then, temporarily stops earlier after forming bending.Measure the time so far, and (second, value once can round up) deposits NVRAM 104 in to be unit with the second.Afterwards, adjust and meet, when restarting, also can drive paper-feed roll with image front end time of imaging portion.
Begin Measuring Time from this image front end time, usually, drive paper-feed roll in the time of the length+α of the paper of setting (α is different because of device).This time also is added to NVRAM 104.Like this, driving time that paper-feed roll rotates is upgraded at any time and is deposited in NVRAM 104.
In addition, when paper-feed roll carries out paper feeding when operation, usually because surface abrasion or adhere to the paper powder, the ability of the transmission paper of paper-feed roll can fail gradually, and therefore, the paper feeding failure can take place easily.
Fig. 4 shows the paper-feed roll accumulation driving time of present embodiment, and the paper supply paperboard is judged clocking value, and an example of the relation at page or leaf interval (the imaging page or leaf at interval).
As shown in Figure 4, the life-span of supposing paper-feed roll is 960Ksec, and till this life-span, every 120Ksec is divided into an interval, each interval is provided with not paper supply paperboard judgement clocking value, and the not paper supply paperboard in each interval judges that clocking value increases with the increase of accumulation driving time.
When beginning paper feeding at every turn, confirm earlier present accumulation driving time is in which interval among Fig. 4, set not paper supply paperboard judgement clocking value according to this result, and be used for judging the not generation of paper supply paperboard.
Utilize above structure, can suppress to take place the not probability of paper supply paperboard.
Further, when the paper supply paperboard does not judge that clocking value is established to such an extent that increase gradually, if the imaging page or leaf does not correspondingly strengthen at interval, the phenomenon of paper supply operation will take place can't finish in the imaging page or leaf interval.Therefore, as shown in Figure 4, the imaging page or leaf is set corresponding to life-span of paper-feed roll at interval.The imaging control part is with reference to the imaging page or leaf spacing distance X of above setting, and it is controlled a page or leaf interval at interval as the minimum imaging page or leaf corresponding to life-span of paper-feed roll.
More than the imaging page or leaf spacing distance of Que Dinging should be the page or leaf spacing distance that can guarantee the image front position, even operating near paper supply not under the paper supply jam detection situation that paper feeding is normally finished before the time.Here, not the paper supply jam detection time never the paper supply paperboard judge that clocking value judges, and the paper supply paperboard does not judge that clocking value is corresponding to the lifetime settings of paper-feed roll.
