Driver 314 is used for optionally discharging ink from printhead 12 with predetermined timing.This driver 314 receives according to the driving control program of exporting from CPU300 and produce the signal of output then among ASIC306, and drives control printhead 12.
Next, with reference to the control that transmits paper and printing by above-mentioned control device being described at the flow chart shown in Figure 21.In the control shown in Figure 21, the mode of supplying with paper P is changed into first pattern or second pattern.In first pattern, plurality of sheets of paper is opened sent to print area 210 off and on.First pattern is the preferential accurate model of printing precision.In second pattern, plurality of sheets of paper is opened sent to print area 210 continuously and sequentially.Second pattern is the preferential quick mode of print speed.
When applying electric power for multifunctional equipment 1, the control beginning.The pattern of user's pressing operation panel 30 is set the button (not shown) to select first pattern or second pattern.When the user wishes accurately to print, select first pattern.When selecting first pattern, the leading edge of the paper P that transmits by paper feed roller 7 with along that of inverse direction rotation contact wire of sending between roller 20a, the 20b 212 (referring to Fig. 5) is being aimed at, the transmission of paper P stops once under this state.Thereby even the leading edge that the leading edge that is transmitted paper P in the leading edge of paper P by paper feed roller 7, also makes paper P with respect under that situation that contact wire of sending between roller 20a, the 20b 212 is tilted with at that contact wire of sending between roller 20a, the 20b 212 is aimed at.With under that state that contact wire of sending between roller 20a, the 20b 212 is aimed at, that begins paper P is transmitted towards print area 210 to sending into roller 20a, 20b in the leading edge of paper P.Give CPU300 with this timed sending, and CPU300 is according to this timing controlled printhead 12.When first pattern of selection (accurate model), the leading edge of paper P does not transmit towards print area 210 under heeling condition, and desired pictorial pattern is printed thus in the position of the leading edge of paper P and synchronous to the control of printhead 12 on the desired position of paper P.
Control section at first detects setting pattern (S1 in Figure 21).Then this control section determine the setting pattern whether be accurate model (intermittently paper pushing mode) (S2).If the setting pattern is accurate model (S2: be), then sign switches to first pattern (S3), and transmission switching device shifter 100 is set at accurate model (S4).Specifically, the balladeur train 13 that stops at by the holding fix place shown in the Po3 among Figure 12 moves to print area 210 significantly along the arrow C direction.Therefore, first slide block 104 that is subjected to biasing spring 106a extruding moves on the arrow C direction along adjustment part 110 in inclined groove 109b inside shown in Figure 11, part 111 receptions is set and remains on this position (position 1 (Po1)) by first then and locate.Under this state, change gear 102 and intermittently paper pushing gear 113 engagements.
In case change gear 102 and intermittently paper pushing gear 113 engagements, the rotation of then sending into driven roller 20a passes to the driving shaft 14 of paper supply unit 6 by idler gear 119a, 119b, as shown in figure 13.Under this state, when inverse direction is rotated, send into driven roller 20a and rotate along inverse direction (counter clockwise direction among Figure 13) at LF motor 42.On the other hand, the gear train 50 of arm 6a inside makes paper feed roller 7 rotate along direction (counter clockwise direction among Figure 13).When direction is rotated, make the described plurality of sheets of paper that is stacked on the carton 5 open the separating member (not shown) of P against the separation inclined plane 8 at the leading edge place that is located at carton 5 at paper feed roller 7, this separating member has great friction coefficient.Then, have only the top paper P to be transmitted (S5 Figure 21) from carton 5 taking-ups and towards leading paper spare 9.At this moment, rotate along inverse direction (counter clockwise direction in Fig. 4), so the paper P that paper feed roller 7 transmits can not send into driven roller 20a and send between the driven voller 20b and pass through owing to send into roller 20a.The leading edge of paper P with at that contact wire of sending between roller 20a, the 20b 212 (referring to Fig. 5) is aimed at.Even under the situation of the leading-edge droop of the paper P that is transmitted by paper feed roller 7, the leading edge of paper P also with at that is aimed at the contact wire of sending between roller 20a, the 20b 212.
Next, as shown in figure 14, LF motor 42 turns over suitable step number along direction, sends into driven roller 20a and rotates (clockwise rotating among Figure 14) along direction, and transmit towards print area 210 at the paper P that sends into driven roller 20a and send between the driven voller 20b.After direction is rotated, paper P is transmitted preset distance in 42 beginnings of LF motor.Therefore, the leading edge of this paper P is set in the printing initiating position place of print area 210 inside.This process is called as " process of advancing ".
Paper feed roller 7 rotates along inverse direction (clockwise direction among Figure 14) during the process of advancing.But, because sending into driven roller 20a is set at bigger than the strength of paper feed roller 7 transmission paper P with the strength of sending into driven voller 20b transmission paper P, so paper P is transmitted sending into roller 20a, 20b by that, and arm 6a swings along counter clockwise direction round driving shaft 14., be used for the strength that paper is pressed on the paper feed roller 7 is died down along the time at arm 6a, when paper feed roller 7 rotates, also do not pass to paper even therefore be used to transmit the strength of paper counterclockwise around driving shaft 14 swings.Paper is thrown off with respect to paper feed roller 7 slips and from paper feed roller 7.
Subsequently, from input such as unshowned outer computer print command the time, make balladeur train 13 move, and from the nozzle of printhead 12 ink is discharged on the paper P surface simultaneously, with printing curve pattern on paper P (S6 among Figure 21) along the Y direction.When balladeur train 13 when the Y direction moves, paper feed roller 7, send into roller 20a, 20b and outlet roller 21a, 21b stop, so paper P stops.When balladeur train moves to another end from an end and finishes printing along the single path of balladeur train along the Y direction, send into roller 20a, 20b and outlet roller 21a, 21b rotate described preset distance along direction, the length that this distance equals that the single path of balladeur train prints along the print area of X-axis line.The rotation of moving and send into roller 20a, 20b and outlet roller 21a, 21b of balladeur train 13 hockets.
When send into roller 20a, 20b and outlet roller 21a, 21b during forward operation or the printing when direction is rotated, driving shaft 14 rotates along inverse direction, and upwards swing of arm 6a.Be used for the strength that paper is pressed on the paper feed roller 7 is died down, the strength that therefore is used to transmit paper does not pass to paper from paper feed roller 7.Though rotate along inverse direction sending into roller 20a, 20b and outlet roller 21a, 21b paper feed roller 7 when direction is rotated, make paper slide with respect to paper feed roller 7, and along direction transmission paper P.
In this advances process, when LF motor 42 beginning forward rotation, the leading edge of paper P with at that contact wire of sending between roller 20a, the 20b 212 is aimed at.Therefore, from that to send into roller 20a, moment elapsed time when 20b begins forward rotation is determined the position of paper P leading edge during that is to the forward rotation of sending into roller 20a, 20b.According to the operation of this timing controlled printhead 12 time, the operation of the leading edge locus of paper P and printhead 12 is synchronous, prints desired pictorial pattern thus on the desired position of paper P.
When printing an EOP (S7 among Figure 21: be), the paper P that begins to be printed sends.In the process of doing like this, LF motor 42 turns over suitable step number (S9 among Figure 21: be) along direction, and the rotation of LF motor 42 stops (S10 among Figure 21) then.Therefore, send into roller 20a, 20b and outlet roller 21a, 21b and rotate pre-determined number, stop then along the direction that transmits paper.The paper P that is printed is passed out to upper position in the carton 5.
Next, determine whether to exist the print data that is used for paper (following one page) described below.If exist or store print data (S11 among Figure 21: be), then repeat process from step S5 to S11.Like this, one of paper P is connect a ground and send print area 210 to.In this pattern, can accurately print for example colour pitcture.
Next the situation of setting second pattern is described.When the user needs flying print, set second pattern.
When determining that the setting pattern is not first pattern among the step S2 at Figure 21, sign is set at second pattern (S12 among Figure 21).Specifically, this sign with expression second pattern is stored in the presumptive area of RAM302 inside.Next, transmission switching device shifter 100 is set at second pattern (S13).In second pattern, print quality is inessential, but print speed is preferential, therefore gives print area 210 with plurality of sheets of paper with opening the P consecutive order.Therefore, send into roller 20a and send into strength that roller 20b transmits paper and be set at greater than paper feed roller 7 and transmit the strength of paper, and the peripheral speed that will send into roller 20a is set at the peripheral speed that is higher than paper feed roller 7.Be set in Figure 15 to continuous paper pushing gear 114 shown in Figure 17 and the speed reducing ratio between the idler gear 120, thereby the peripheral speed of sending into roller 20a is higher than the peripheral speed of paper feed roller 7.
For transmission switching device shifter 100 being set at second pattern (S13 among Figure 21), balladeur train 13 moves scheduled volume along the direction of arrow E, as shown in figure 12.Therefore, as shown in figure 11, divide the 13a place along E direction extruding abutment 104a in first engagement stepped-portion of balladeur train 13.When the direction that makes balladeur train 13 along arrow E moves, abutment 104a is arranged on second part 112 is set (position 2 Po2) is located.Part 112 is set (position 2 Po2) is located, even move along the arrow C direction after the balladeur train 13, also abutment 104a can be remained on second part 112 places are set by adjacent part 104a being arranged on second.Abutment 104a be arranged on second part 112 places are set during, as Figure 15 to shown in Figure 17, change gear 102 and continuously paper pushing gear 114 be meshing with each other, and transmission of power is given the driving shaft 14 of the rear end of arm 6a by an idler gear 120.
As shown in figure 15, rotate so that when beginning to send into paper P along direction, send into driven roller 20a and rotate, and paper feed roller 7 also rotates along direction along direction (clockwise direction among Figure 15) at LF motor 42.7 of paper feed rollers are isolated a paper P topmost, and this paper P are given lead paper spare 9 (S14 among Figure 21).Arrive when sending into driven roller 20a and sending into contact wire 212 between the driven voller 20b at the fore-end of paper P, owing to send into roller 20a and rotate along direction, so during the front end of paper P is pulled to and sends into driven roller 20a and send between the driven voller 20b, transmit towards print area 210 then.
Open P when a piece of paper and be maintained at that sending between roller 20a, the 20b and when contacting (referring to Figure 16) with paper feed roller 7, because that transmits the strength of the strength of paper greater than paper feed roller 7 transmission paper to sending into roller 20a, 20b, and the peripheral speed of sending into driven roller 20a is set at the peripheral speed that is higher than paper feed roller 7, so this paper P transmits towards print area 210 with the transfer rate of sending into roller 20a.This paper P slides with respect to paper feed roller 7.Because that transmits the front paper to sending into roller 20a, 20b with fast speeds, and paper feed roller 7 transmits paper subsequently with slower speed, so, current facial tissue open and subsequently paper arrive that when sending into roller 20a, 20b, paper and the space is provided between the paper subsequently in front.
In continuous paper pushing mode, after paper sensor 116 senses the leading edge of paper P, when that reaches scheduled volume to the amount of spin of sending into roller 20a, 20b, the printing (S15 in Figure 21) of beginning on paper P.After paper sensor 116 detected the leading edge of paper P, when that had rotated this scheduled volume to sending into roller 20a, 20b, that stopped operating to sending into roller 20a, 20b.At this constantly, paper is positioned at the printing initiating position place.When regulating paper at this printing initiating position place, beginning printing (S15 among Figure 21).
In printing, make balladeur train 13 move along the Y direction, ink is discharged on the surface of paper P from the nozzle of printhead 12 simultaneously, with printing curve pattern on paper P (S15 among Figure 21).When balladeur train 13 when the Y direction moves, paper feed roller 7, send into roller 20a, 20b and outlet roller 21a, 21b stop, so paper P stops.When balladeur train 13 moves to another end from an end and finishes printing along the single path of balladeur train along the Y direction, send into roller 20a, 20b and outlet roller 21a, 21b rotate described preset distance along direction, the length that this distance equals that the single path of balladeur train prints along the print area of X-axis line.The rotation of moving and send into roller 20a, 20b and outlet roller 21a, 21b of balladeur train 13 hockets.
Next, receiving expression from external equipment when having the order will be printed on the print data on one page (paper subsequently) down (S16: be), then process advances to S17.In this case, when the printing of paper P finishes in front (S17: be), determine that then current first pattern that is masked as still is second pattern (S18).(S18: in the time of second), LF motor 42 continues to rotate along direction, and sends into driven roller 20a, sends driven roller 21a and paper feed roller 7 continues to rotate (S19) along direction being masked as second pattern.Controller has appendage, and in the moment when finishing the printing of front paper, this appendage begins paper feed roller 7 and that is to sending into the continuous rotation of roller 20a, 20b.Therefore, discharge this front paper (page or leaf formerly), and paper (page or leaf subsequently) is transported to printing initiating position subsequently.After paper sensor 116 detected the leading edge of paper P subsequently, when that rotated this scheduled volume to sending into roller 20a, 20b, this paper was positioned at the printing initiating position place.After paper sensor 116 detected the leading edge of paper P, paper feed roller 7 and that rotated continuously and do not stop sending into roller 20a, 20b, up to that to till sending into roller 20a, 20b and rotating this scheduled volume.After this process, step turns back to S15, and beginning is in upward printing of one page (page or leaf subsequently) down.
Paper feed roller 7 is very fast to the printing that the rotation continuously of sending into roller is opened plurality of sheets of paper with that.But this rotates not necessarily continuously, can repeat the circulation change that makes paper feed roller 7 and send into roller 20a, 20b alternate rotation and stop continuously.In this case, when the contact position between roller and the paper during in the past the facial tissue leading edge of opening moves to the leading edge of paper subsequently through the mid portion of front paper and trailing edge, repeat this identical circulation change.When in continuous paper pushing mode, being used for the printing that plurality of sheets of paper opens, repeat paper feed roller 7 with that to sending into this identical circulation change of roller 20a, 20b.
Figure 17 illustrate discharge front paper P and subsequently paper P be transported to the state of printing initiating position.Set second pattern during, not have to suspend by sending into driven roller 20a and sending under the situation that driven voller 20b transmits paper P, continuously and the described plurality of sheets of paper of supply/discharge sequentially open P, so can carry out the flying print process.
Next, to describing carrying out during second pattern situation about when not having the print data that is used for paper subsequently, controlling.In the step S16 of Figure 21, when not receiving expression when having the order to be printed on down the print data on one page (S16: deny), promptly when no longer having the print data that is used for paper P subsequently, the paper P (paper) that is arranged on print area 210 places carries preset distance (S20) along transport direction.This preset distance is approximately three print lines.When paper has been transmitted preset distance (S20: be), then sign is switched to first pattern (S21).Under this state, carry out on the paper P in being arranged on print area 210 and print (S17).When this printing finishes (S17: be), inquire current sign (S18).
When in step S18, determining to be masked as first pattern (S18: in the time of first), carrying out processing controls (S30) on the paper subsequently.In the flow chart of Figure 22, demonstrate the details of this control.
At first, when the printing that finishes described one page of front paper P when being (S17 in Figure 21 for), determine whether paper sensor 116 is out (S31 among Figure 22).Specifically, whether the leading edge portion of definite paper P subsequently is through existing the part of paper sensor 16.(S31: not) when paper sensor 116 is the pass, promptly when the leading edge of paper P does not also arrive paper sensor 116 subsequently (referring to Figure 18), the first half ones of paper P are arranged on and lead in the paper spare 9 subsequently, and the latter half of of this paper P is arranged in the carton 5, if therefore subsequently paper P1 turn back to carton 5 and just reduced the processing time.In addition, when by print area 210 unwritten paper P being discharged, relate to paper P1 is reset at effort in the carton 5, therefore preferably making subsequently, paper P1 turns back to carton 5.
In the superincumbent situation, paper P1 turns back to carton 5 in order to make subsequently, and paper feed roller 7 rotates (S32 among Figure 22) along inverse direction.In this case, balladeur train 13 is mobile from the position of print area along the arrow E direction among Figure 12, and abutment 114a is arranged on position 1 (Po1) locates.In this position, change gear 102 and intermittently paper pushing gear 113 engagements, as shown in figure 14., send into driven roller 20a and send driven voller 21a and rotate when direction is rotated at LF motor 42, therefore transmit front paper P along transport direction along direction.On the other hand, paper feed roller 7 rotates along inverse direction.Rotate scheduled volume (S33 among Figure 22) when stopping (S34) then at paper feed roller 7 along inverse direction, paper P1 turns back to the stacked position (referring to Figure 19) in the carton 5 subsequently.
When the printing of one page front paper P is finished (when the S17 in Figure 21 when being) the moment, at paper sensor 116 (S31 among Figure 22: be) when opening, the leading edge portion of paper P1 is by existing the position of paper sensor 116 subsequently.In this case, LF motor 42 rotates along inverse direction, paper feed roller 7 forward rotation, and send into driven roller 20a and rotate (S35 among Figure 22) along inverse direction.During S35 in carrying out Figure 22, abutment 114a is arranged on position 1 (Po1) and locates and be under the connection status shown in Figure 13.Under this state, LF motor 42 rotates scheduled volumes (S36 among Figure 22), and subsequently paper P1 leading edge with aim at the contact wire 212 of sending into driven roller 20a and send between the driven voller 20b.Under this state, the rotation of LF motor 42 stops once, and the rotation of sending into roller 20a and paper feed roller 7 also stops (S37 among Figure 22).Subsequently, rotate along direction, send into driven roller 20a and send driven roller 21a and rotate to discharge paper P 1 along direction thereby make by making LF motor 42.Under this state, paper feed roller 7 rotates (referring to Figure 19) along inverse direction, therefore at paper feed roller 7 (S39) when inverse direction is rotated scheduled volume, makes the P2 of paper subsequently that follows this paper P1 be back to carton 5.
Should be noted that, as shown in figure 16, along leading paper spare 9 from being L1 to the distance of sending into driven roller 20a and sending into the contact wire 212 the driven voller 20b at the stack paper P on the carton 5 and the contact wire 214 between the paper feed roller 7, and from being L2 at stack paper P on the carton 5 and the contact wire 214 between the paper feed roller 7 to the distance the separating member that is separating the inclined plane 8.
In the situation of paper feeding operation continuously, the moment when trailing edge of paper P breaks away from contact wire 214 between paper P and paper feed roller 7 in front, paper P1 is by the rotational conveyance of paper feed roller 7 subsequently, so distance L 2 becomes along front paper P and the lap of the throughput direction of paper P1 (lap) subsequently.Difference between L2 and L1 is set at longer than predetermined value, and (it is predetermined value at least that the difference (V1-V2) between the V1＞V2) is set at the peripheral speed V2 of peripheral speed V1 that sends into roller 20a and paper feed roller 7, the trailing edge that current thus facial tissue is opened P is by when sending into driven roller 20a and sending into contact wire 212 between the driven voller 20b, and the leading edge no show of paper P1 is subsequently being sent into driven roller 20a and sent into contact wire 212 between the driven voller 20b.Specifically, when when sending into driven roller 20a and sending between the driven voller 20b, the trailing edge of paper P and can form suitable space (paper is at interval) between the leading edge of paper P1 subsequently in front.Therefore, even when supply/conveying plurality of sheets of paper is opened P continuously, also can in print area 210, print and every all print datas that paper P is corresponding fully.Specifically, in print area 210, therefore the trailing edge of front paper P and the leading edge of paper P1 is not overlapped subsequently can not print on the space between two pieces of paper are opened.In the superincumbent situation, the trailing edge of paper P breaks away from paper feed roller 7 and when just being carried sending into roller 20a, 20b by that in front, control and make and to begin the supply process of paper P1 subsequently, obtain to obtain more reliably top paper effect at interval thus by paper feed roller 7.
According to the present invention, as mentioned above, be stacked on therein on the carton 5 paper P can by 7 one of paper feed rollers connect a ground offer this paper P of leading paper spare 9 and being provided by that in the structure of sending into roller 20a, 20b and flowing to print area 210, that is made of the driven voller 20b that sends into that sends into driven roller 20a and be admitted to driven roller 20a pressurization that is driven by LF motor 42 sending into roller 20a, 20b.In addition, that is set at transmission strength greater than paper feed roller 7 to the strength of sending into roller 20a, 20b and transmitting paper, and the peripheral speed of sending into driven roller 20a is set at the peripheral speed that is higher than paper feed roller 7.And control device is arranged to following control, thereby when existence is used for the print data of paper P1 subsequently, sends into roller 20a and paper feed roller 7 and driven by rotation continuously along equidirectional.Therefore, plurality of sheets of paper is opened P can flow to print area 210 and the printing of consecutive order ground consecutive order, and therefore having realized can be to open the effect of carrying out printing on the P at plurality of sheets of paper at a high speed.
In addition, send into driven roller 20a and paper feed roller 7 and constitute, therefore realized to make the effect simple in structure that is used to supply with and provide paper according to the mode that drives by single drive motors (LF motor) 42 rotation.
In the present embodiment, because the front end of arm 6a is provided with paper feed roller 7, so the draw out operation of carton 5 does not hinder paper feed roller 7.In addition, when sending into driven roller 20a and contact with paper feed roller 7, arm 6a swing prevents that thus paper feed roller 7 from hindering that to transmit paper to sending into roller 20a, 20b at a piece of paper.
Owing to be provided with transmission switching device shifter 100, so can cut one on paper and connect a location and they are sent to the paper feeding operation at intermittence of print area 210 and send into many high speed paper feedings that cut paper with being used for consecutive order and switch between operating being used to make.Utilize the mobile execution of balladeur train 13 to be used for the operation of this switching, so do not need too much mechanism.
