Summary of the invention
In Japanese Patent Application Laid-Open No.2001-301998, utilize the described schedule time so that form described suitable space.Control program depends on elapsed time after paper sensor detects the leading edge of front paper.
In Japanese Patent Application Laid-Open No.2001-301998, there is a problem, promptly must regulate the described schedule time according to antiquarian.For example, when from the long paper of carton supply, must adopt the long schedule time, and when from the short paper of carton supply, the schedule time that must adopt weak point.The control program of paper-feeding mechanism must depend on antiquarian and change.When known to antiquarian is not chopping machine, can not select the suitable schedule time.
In addition, in the disclosed technology of Japanese Patent Application Laid-Open No.2001-301998, control program depends on elapsed time after paper sensor detects the leading edge of front paper.That is, control program depends on the position of the paper that paper-feeding mechanism transmits and changes.This makes control program very complicated.Paper feeding speed also depends on the position of paper and slows down.
The present invention will solve these traditional problems.
The antiquarian variation an object of the present invention is to provide a kind of technology, even wherein also can be adopted identical control program.
Another object of the present invention provides a kind of technology, even wherein antiquarian is not a yet paper and form described suitable space subsequently between the paper in front known to the chopping machine.
Of the present invention also have a purpose to provide a kind of control program, and this control program does not rely on the position of the paper that paper-feeding mechanism transmits.This control program does not depend on the position of the paper that paper-feeding mechanism transmits and changes.
Chopping machine of the present invention comprises: paper feed roller, take out a piece of paper and open, and this paper sent to lead paper spare its plurality of sheets of paper in being stacked on carton is opened; And a pair of roller of sending into, they receive paper feed roller and send that paper of leading paper spare to, and send this paper to print area.
Here, that is to sending in the roller one by rotations such as motors, and these another modes according to the rotation of sending into roller of following the former of sending in the roller are rotated.Specifically, that constitutes by sending into driven roller and sending into driven voller sending into roller.In addition, the circumferential velocity (transfer rate) of sending into driven roller is faster than the circumferential velocity (transfer rate) of paper feed roller.And that is set at bigger than the strength (conveying capacity of paper feed roller) of paper feed roller transmission paper to the strength (that is to sending into the conveying capacity of roller) of sending into roller transmission paper.
Chopping machine of the present invention comprises control setup, and this control setup is used for according to programming control paper feed roller and that sending into the rotation of roller, and this program does not rely on paper feed roller and that position to the paper sending into roller and transmit.That is, this program do not depend on the position of the paper that roller transmits and changes, no matter and the contact position between roller and paper that moves to trailing edge from the leading edge of paper how, controller is the rotation of control roll equably all.According to control program of the present invention, no matter contact position how, paper feed roller and that all rotate in an identical manner to sending into roller.
Paper feed roller refers to along take out a piece of paper from carton along the rotation of direction to be opened and sends it the rotation of the direction of leading paper spare to.When inverse direction was rotated, the paper of leading on the paper spare turned back in the carton at paper feed roller.That refers to along making from leading the rotation that paper that paper spare sends is sent to the direction of print area along the rotation of direction sending into roller., can not enter into and send into driven roller and send between the driven voller sending into roller when inverse direction is rotated at that from leading paper that paper spare sends.From lead paper spare with paper send to rotate along inverse direction that when sending into roller, the leading edge of paper is sent into driven roller and is sent into the contacted contact wire of driven voller and aim at making.That that rotates along inverse direction is positioned at function on the fixed position to sending into the roller performance with paper front edge.

As shown in figure 10, the first biasing spring 106a is provided with round main shaft 103.The first biasing spring 106a pushes second slide block 105 along the direction of arrow C.The second biasing spring 106b is provided with round main shaft 103.The second biasing spring 106b is along the direction extruding change gear 102 of arrow E.The biasing force of the first biasing spring 106a is greater than the biasing force of the second biasing spring 106b.
As shown in figure 11, being formed with first engagement stepped-portion in balladeur train 13 divides the 13a and second engagement stepped-portion to divide 13b.When the arrow E direction moved, the abutment 104a of first slide block 104 divided the 13a or second engagement stepped-portion to divide 13b to engage with first engagement stepped-portion at balladeur train 13.
As shown in Figure 8, guide block 107 is fixed on the framework 39.In guide block 107, be formed with guide groove 109, and the abutment 104a of first slide block 104 is embedded in the guide groove 109.As shown in figure 11, guide groove 109 comprises along horizontal channel part 109a that is extended by the direction of arrow C and E (Y-axis line) expression and the inclined groove part 109b that is communicated with the left end portion of horizontal channel part 109a.The adjustment part 110 that extends downwards from the top of guide block 107 is inserted in the middle body of inclined groove part 109b.This adjustment part 110 is along extending with the direction shown in arrow C and the E.Inclined groove part 109b is provided with stair shape first and part 111 and second is set part 112 is set.On inclined groove part 109b, be formed with and be provided with first second wall 218 that part 111 and second is provided with the first wall 216 of part 112 and extends to opposition side is set.First is provided with part 111 and second is provided with part 112 and is formed on the first wall 216, and does not form any part that is provided with on second wall 218.
As shown in figure 11, when balladeur train 13 was arranged in position facing to paper P, balladeur train 13 was away from maintenance mechanism 36 and not along the direction extruding abutment 104a of arrow E.Under this state, the first biasing spring 106a makes second slide block 105, first slide block 104 and change gear 102 slide along main shaft 103 on the direction of arrow C.Abutment 104a is arranged on first part 111 places is set.This position is called as " position 1 " (Po1).At this moment, change gear 102 and intermittently paper pushing gear 113 engagements.
When the direction of arrow E moved, first engagement stepped-portion of balladeur train 13 was divided 13a direction extruding abutment 104a along arrow E at balladeur train 13.Therefore, make change gear 102, first slide block 104 and second slide block 105 on the direction of arrow E, slide along main shaft 103.Because first slide block 104 is subjected to second slide block 105 from the right side extruding, so abutment 104a is pressed against on the lower wall (first wall 216) of inclined groove 109b.At balladeur train 13 abutment 104a is pushed when with second part 112 cooresponding positions being set, abutment 104a moves downward to enter second part 112 is set.Abutment 104a enters second position that part 112 is set and is called as " position 2 " (Po2).In the situation of this position 2, change gear 102 and paper pushing gear 114 engagements continuously.In Figure 10, demonstrate this state.
Further when the direction of arrow E moves, first engagement stepped-portion of balladeur train 13 is divided 13a direction extruding abutment 104a along arrow E at balladeur train 13.Pressurized abutment 104a advances to horizontal channel part 109a from inclined groove part 109b.In case abutment 104a enters horizontal channel part 109a, then second engagement stepped-portion of balladeur train 13 is divided 13b extruding abutment 104a.When abutment 104a is in position after and then entering horizontal channel part 109a when (this position is called as " position 3 " (Po3)), change gear 102 with safeguard gear 115 engagements.
With top opposite states, when 4 (Po4) were mobile from the position along the direction of arrow C, abutment 104a moved to inclined groove part 109b from horizontal channel part 109a in sledge position 13.At this moment, abutment 104a is by dividing the 13a and second engagement stepped-portion to divide the ladder between the 13b to receive in first engagement stepped-portion of balladeur train 13, so abutment 104a moves above the adjustment part 110 of Figure 11 along the direction of arrow C.Be resisted against when abutment 104a slides on adjustment part 110 on the left-leaning inclined-plane of inclined groove part 109b shown in Figure 11, (second wall 218) moves afterwards along left-leaning inclined-plane, part 111 is set engages with first then.On the upper wall (second wall 218) of guide groove 109, do not exist part is set, so abutment 104a 4 moves to position 1 from the position.
Move to right-hand member then after the C direction moves at balladeur train 13 along the E direction, abutment 104a 1 moves to position 2 from the position, and 2 move to position 3 from the position, and 3 move to position 4 from the position, and 4 moves to position 1 from the position.Balladeur train 13 repeats to move to right-hand member then along moving that the C direction moves along the E direction, and abutment 104a repeats from the position 1 → 2 → 3 → 4 → 1 motion cycle simultaneously.Move to position 1 then when the C direction moves at balladeur train 13 along the E direction, change gear 102 remains on 1 place, position.Move to position 2 then when the C direction moves in sledge position 13 along the E direction, change gear 102 remains in the position 2.
Position 3 (Po3) be holding fix also be maintenance position.Do not applying under the state of electric power to multifunctional equipment 1, balladeur train 13 stops at the upper position place of maintenance mechanism 36, and transmission shifter 100 is in 3 places, position.When switchover apparatus 100 is in 3 places, position, safeguard gear 115 by change gear 102 with send into driven roller 20a and be in transmission connection.When LF motor 42 rotated under this state, the cap portion 36a of maintenance mechanism 36 rose, and covered the nozzle surface of printhead 12 from the below.Therefore, prevent that ink is dry in the nozzle of printhead 12.And, maintenance mechanism 36 is provided with the aspirating pump (not shown), and when LF motor 42 transmission shifter 100 be in rotate under the state of position 3 and safeguard gear 115 by change gear 102 when sending into driven roller 20a and be in transmission connection, LF motor 42 starts aspirating pump.When starting the aspirating pump of maintenance mechanism 36,, therefore safeguard the ability of discharging ink from nozzle with the bubble removal that is blended in the buffer container that is located on the printhead 12.
As shown in Figure 5, between printhead 12 and outlet roller 21a, 21b, be provided with roller 50.This roller 50 is pressed in paper P on the platen 11.Owing to be provided with roller 50,, therefore prevent that paper P is contaminated so can not make the nozzle surface moving contact of paper P and printhead 12.
In addition, on the upstream side of sending into roller 20a, 20b, be provided with the paper sensor 116 of the existence that is used for sensing paper P.The moment that the trailing edge that the leading edge that paper sensor 116 detects paper P arrives moment of paper sensor 116 and paper P and paper sensor 116 separate.
Below with reference to Figure 20 the control part (control setup) of multifunctional equipment 1 is described.This control part is used to control the whole operation of multifunctional equipment 1.
Control part is configured to computing machine, and it mainly comprises CPU300, ROM301, RAM302 and EEPROM303, and is connected with application-specific IC (ASIC) 306 by bus 305.
ROM301 stores the program of the various operations that are used to control multifunctional equipment 1 etc. therein, and RAM302 is as the storage area of the employed various data item of temporary transient storage when CPU300 carries out these programs.
NCU (network control unit) 317 is connected with ASIC306, and the signal of communication of importing from public circuit by NCU317 inputs to ASIC306 then by the MODEM318 demodulation.In addition, ASIC306 by facsimile transmission etc. with image data transmission when outside, this view data is exported to public line by NCU317 then by the MODEM318 modulation.
ASIC306 is according to produce the phase excitation signal of communicating by letter with for example LF motor 42 etc. from the order of CPU300.These signals offer the driving circuit 311 of LF motor 42 or the driving circuit 312 of CR motor 24, and by driving circuit 311 or driving circuit 312 drive signal is communicated by letter to LF motor 42 or CR motor 24, with the forward and the reverse operating of control LF motor 42 and CR motor 24, stop etc.
In addition, be used to read in image on the manuscript or character scanner device 33 (for example CIS), be used for the keyboard 30a of guidance panel 30 and Liquid Crystal Display (LCD) (LCD) 31 carry out the signal transmission panel interface 313, be used for external device for example Personal Computer parallel interface 315, USB interface 316 etc. of carrying out data transmission by parallel cable or USB cable be connected with ASIC306.
And, be used to detect maintenance mechanism 36 the cam (not shown) turned position switch 118, be used for by lead paper spare 9 detect when supplying with paper P near the mode of print area 210 leading edge locus of paper P and posterior border position paper sensor 116, be used to detect the amount of spin of sending into roller 20a rotary encoder 44, be used to detect balladeur train 13 and be connected with ASIC306 along the linear encoder 37 of the position (current location) of Y direction etc.
Next, with reference to the control that transmits paper and printing by above-mentioned control setup being described at the diagram of circuit 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 mode initialization button (not shown) of user's pressing operation panel 30 is 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 transmits paper P in the leading edge of paper P by paper feed roller 7 with respect at that to sending under the contact wire 212 bevelled situations between roller 20a, the 20b, the leading edge that also makes paper P 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 fixed-time control 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 part at first detects setting pattern (S1 in Figure 21).Then this control part 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 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 axle drive shaft 14 of paper supply unit 6 by intermediate 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 (anticlockwise direction among Figure 13) at LF motor 42.On the other hand, arm 6a in-to-in train of gears 50 makes paper feed roller 7 rotate along direction (anticlockwise 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 dip 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 (anticlockwise 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 print area 210 in-to-in printing initiating position places.This process is called as " process of advancing ".
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, axle drive 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 forwards to 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 fixed-time control 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 customer requirement 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 RAM302 in-to-in presumptive area.Next, transmission 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 circumferential velocity that will send into roller 20a is set at the circumferential velocity 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 reduction ratio between the intermediate gear 120, thereby the circumferential velocity of sending into roller 20a is higher than the circumferential velocity of paper feed roller 7.
For transmission 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 axle drive shaft 14 of the rear end of arm 6a by an intermediate 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 circumferential velocity of sending into driven roller 20a is set at the circumferential velocity 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 seeing that 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 device 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 did not stop sending into roller 20a, 20b continuous rotation, 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.
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 diagram of circuit 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 coupled condition 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 P1 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 turn 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 dip 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 circumferential velocity V2 of circumferential velocity 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 cooresponding all print datas of paper P 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 circumferential velocity of sending into driven roller 20a is set at the circumferential velocity that is higher than paper feed roller 7.And control setup 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, has therefore realized and can open the effect of carrying out printing on the P at plurality of sheets of paper by at 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 motor (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 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.
