Paper feeder

Technical field

The present invention relates to a kind of paper feeder, and the plurality of sheets of paper that this paper feeder should offer the processing equipment that paper is handled is opened and is housed in accepting unit, and has the transfer path that paper is sent to processing equipment from accepting unit.

Background technology

The processing equipment that the paper that transmits from paper feeder etc. is handled for example comprises image processing system.In recent years since, image processing system is being obtained progress aspect multifunction and the print out rate processing high speed.Developed for example have the duplicator pattern, a plurality of tupes such as printer mode, FAX pattern, the image processing system of printing treatment speed per second more than 1.This high speed image forms in the device, needs to provide the paper feeder of a large amount of paper.This essentiality especially significantly shows near the device that also will print when users such as printer mode and FAX pattern are not image processing system.

Particularly in the FAX pattern, must have high-capacity paper feeder.This is because for the bulk information that arrives under the situation about being absent from the scene users such as nights, do not carry out printing and when being stored in the memory device in the image processing system in order to prevent that paper from using up, not only need high-capacity memory device, and will be stored in the memory device information after the printing can cause time waste.

But even high-capacity paper feeder, the number of accommodating of its paper also is limited, probably is controlled at 2000-4000.Because along with paper is accommodated the increase of number, it is big that the load of lift system becomes, and accommodates number when superfluous when paper, need make lift system is strong design, maximization, expensiveization that therefore can cause device, and it is difficult that the precise adjustment of paper height also becomes.In addition, the height and position that leans on last paper most that lift system is opened for the plurality of sheets of paper that lamination is accommodated keeps within the limits prescribed, can promote at any time.

Therefore, compare, developed high capacity paper feeder with the adjacent setting of image processing system with paper feed unit is set in image processing system.For example, the spy opens flat 5-193766 communique and discloses and a kind ofly to accommodate number of pages and have a plurality of paper accepting units in order to increase, with the stacked paper feeder of the vertical multilayer of each accepting unit.The paper feeding mouth that the paper that paper feeder provides is communicated with image processing system receives.The paper feeding mouth of image processing system is arranged on preposition in order to be communicated with paper transport path.

But, the paper feeding mouth of image processing system is in order to be communicated with paper transport path and to be arranged on the preposition, in existing paper feeder, form curve the transfer path in the paper feeder till from accepting unit to the paper feeding mouth, wherein the height of above-mentioned accepting unit is provided with differently with the paper feeding mouth of image processing system.Therefore, in paper feeder, chance that the paper in the transmission bends increases, and paper is easy to bending, thereby causes the generation of stopping up and the decline of printing quality.

The object of the present invention is to provide a kind ofly can provide a large amount of paper, and the paper feeder that paper bending and can preventing when transmitting is stopped up when paper from transmitting.

Summary of the invention

Paper guide 8B and 9B as guide member of the present invention are arranged on output unit 7B.Paper guide 8B and 9B are respectively along the folded state of paper feeder 1B side and supported free to rotately between the running condition of upper support in the horizontal direction.Paper guide 8B and 9B are in running condition, and the regulation paper is from the direction of output unit 7B output.

Upstream one side of transfer path RB is provided with receiving element 10B.Receiving element 10B is provided with on the side of an opposite side of the side of the paper feeder 1B that is provided with output unit 7B, has the height roughly the same with output unit 7B.Receiving element 10B opens to the outside of paper feeder 1B, and the paper that will provide from paper feeder 1B outside receives the inside of paper feeder 1B.Receiving element 10B is the shape that can be communicated with the output unit 7B of the paper feeder of the same structure that is configured in direction of transfer upstream one side.

Fig. 2 is along the paper feeding direction of the paper constitution diagram that disposes arranged side by side with three paper feeder 1A, 1B, 1C.Paper feeder 1A, 1C have identical structure with paper feeder 1B respectively.For paper feeder 1B, the paper feeder 1C that is positioned at direction of transfer upstream one side is equivalent to of the present invention first other paper feeders, and the paper feeder 1A that is positioned at direction of transfer downstream one side is equivalent to of the present invention second other paper feeders.

And paper feeder 1B then is of the present invention first other paper feeders with respect to paper feeder 1A, is of the present invention second other paper feeders with respect to paper feeder 1C.

In addition, the right side of paper from Fig. 2 begins to transmit to the left.Below the relation of paper feeder 1A and paper feeder 1B is described, the relation of paper feeder 1B and paper feeder 1C also is the same.

Paper feeder 1A, 1B be configuration side by side laterally, so that the receiving element 10A of the paper feeder 1A of paper conveyance direction middle and lower reaches one side is relative with the output unit 7B of the paper feeder 1B of upstream one side.Except with paper feeder 1A as image processing system 100 disposed adjacent of processing equipment, the paper guide 8B of each paper feeder 1B, 1C, 8C, 9B, 9C are set to running condition, are inserted into receiving element 10A, the 10B of paper feeder 1A, the 1B adjacent with downstream one side respectively.

The size of the paper guide 9B of the paper feeder 1B relative with the back side of paper is: when being inserted into the paper feeder 1A adjacent with downstream one side, the paper SB in transmitting can be directed to plurality of sheets of paper on the placing plate 2A that is placed on paper feeder 1A open in by the surface of last paper SA.By with the paper guide 8B of paper feeder 1B, the receiving element 10A that 9B is inserted into paper feeder 1A, the transfer path RA of the paper feeder 1A of the transfer path RB of paper feeder 1B and downstream one side is communicated with.

The configuration of pick-up roller 3A and transfer roller 6B is: before the allocation position of the rear end of the paper SB in the transmission by the transfer roller 6B of paper feeder 1B, the front end of the paper in the transmission arrives the allocation position of the pick-up roller 3A of paper feeder 1A.That is, the distance L 1 between the transfer roller 6B of the paper feeder 1B of the pick-up roller 3A of paper feeder 1A and upstream one side is set shortlyer than the size L2 of the direction of transfer of the paper SB that transmits.

Particularly, pick-up roller 3A is configured to: the top ends of the paper from the placing plate 2 begins the position of 50mm-60mm and transmits paper.Therefore, paper SB also transmits by the pick-up roller 3A clamping of paper feeder 1A and by pick-up roller 3A by the transfer roller 6B clamping of paper feeder 1B and in during by transfer roller 6B transmission.Therefore, when transmitting paper SB, can not interrupt yet, can suppress to transmit and stop up the conveying capacity of paper SB through a plurality of paper feeder 1A, 1B.

By paper feeder 1B provide and by the paper SB that receiving element 10A receives be directed and be sent on the placing plate 2A by the surface of last paper SA.That is, the surface of paper SA constitutes the part of transfer path RA.

The propulsive effort of transfer roller 6B by paper feeder 1B, the paper SB that transmit on the surface of paper SA in paper feeder 1A during by the transfer roller 6B clamping of paper feeder 1B in, pick-up roller 3A clamping top ends by the paper feeder 1A that descends with predetermined sequential, and the pick-up roller 3A by paper feeder 1A transmits, and further the transfer roller 6A by paper feeder 1A continues to be sent to downstream one side.

As mentioned above, the paper that is housed in paper feeder 1B is through the transfer path RB of paper feeder 1B and be configured in the transfer path RA of the paper feeding dress 1A of paper feeder 1B downstream one side, is sent to image processing system 100.That is, be housed in the transmission of paper of paper feeder 1A and the transfer path RA that paper feeder 1A is used in the transmission that is housed in the paper of paper feeder 1B, 1C jointly.

As shown in Figure 3, paper feeder 1A, 1B, 1C are configured in the side of image processing system 100 side by side.Paper feeder 1A, 1B, 1C can increase and decrease its number according to the number of pages of paper in the image processing system 100.And paper feeder 1A, 1B, 1C are mutually identical structures, so configuration sequence is unrestricted.

Image processing system 100 in the present embodiment is implemented image by the image forming course of electrofax mode to paper and is formed processing.Image processing system 100 has paper feeding box 102,103 in the bottom, have row's paper disc 104 on top.

Between paper feeding box 102,103 and the row's paper disc 104, be provided with paper transport path F1.Near paper transport path F1, dispose photosensitive drums 105.Be provided with around the photosensitive drums 105: Charging system 106, light scanning unit 107, developing cell 108, transfer device 109, cleaning unit 110, and not shown neutralizer.

Upstream one side leaning on the paper conveyance direction than photosensitive drums 105 is provided with the resistance roller 111 that the transfer position of adjustment between photosensitive drums 105 and transfer device 109 provides the sequential of paper, leaning on downstream one side than photosensitive drums 105, is provided with fixing device 112.

Charging system 106 makes the periphery of photosensitive drums 105 wear predetermined potential.Light scanning unit 107 forms electrostatic latent image according to the view data from the outside input at the outer peripheral face of photosensitive drums 105.Developing cell 108 provides toner on the outer peripheral face of photosensitive drums 105, make electrostatic latent image visual, thereby forms toner image.

The toner image that is formed on the photosensitive drums 105 is transferred on the paper by transfer device 109, and passes through fixing device 112 photographic fixing on paper.Photographic fixing paper and then the row's of being output to paper disc 104 of toner image.After toner image was transferred to paper, residual toner to the outer peripheral face of photosensitive drums 105 was recovered by cleaning unit 110, and the electric charge of photosensitive drums 105 outer peripheral faces is removed by neutralizer.

And image processing system 100 has surperficial back side counter-rotating that makes paper and the counter-rotating transfer path F2 that is sent to transfer position for the back side of the paper that formed image on a face forms image.

Further, image processing system 100 has the paper transport path F3 that collaborates with paper transport path F1 between paper feeding box 102,103 and transfer position.The roughly horizontal setting of paper transport path F3.Paper transport path F3 and be arranged on image processing system 100 sides manual pallet 113, and the paper receiving unit 114 that the paper that provides from external device (ED) is provided be communicated with, will be sent to transfer position from the paper that manual pallet 113 or paper receiving unit 114 provide.

Paper feeder 1A and image processing system 100 adjacent settings make the paper receiving unit 114 of output unit 7A and image processing system 100 relative.The paper that is housed in paper feeder 1A, 1B, 1C is provided to paper transport path F3 from the paper receiving unit 114 of image processing system 100, further is sent to transfer position.For example, the paper that is housed in paper feeder 1C passes through the transfer path RB of transfer path RC, the paper feeder 1B of paper device 1C, reaches the transfer path RA of paper feeder 1A, be provided in the image processing system 100 from the paper receiving unit 114 of image processing system 100, and be sent to transfer position.

Because paper feeder 1A, 1B, 1C are configured in the side of image processing system 100 side by side, so paper transport path RA, RB, RC roughly are the shape of straight line.Therefore can compare by more transfer path with the bending machine that is arranged on the paper feeder of prior art, be difficult to bending occur, thereby can suppress to transmit the generation of obstruction along transfer path RA, the RB of paper feeder 1A, 1B, 1C, the paper that RC transmits.And because paper can not bend, the paper that transmits in the inside of transfer path RA, RB, RC and image processing system 100 can not deform yet, and can prevent that therefore the quality that forms image from descending.

Further, in paper feeder 1A, 1B, 1C, be positioned at placing plate 2A, 2B and constituted the part of transfer path RA, RB by the surface of last paper SA, SB, so needn't form transfer path separately, can realize the miniaturization of paper feeder 1A, 1B, 1C.

And the configuration sequence of paper feeder 1A, 1B, 1C is unrestricted, therefore can improve the efficiency of operation that is provided with of paper feeder 1A, 1B, 1C.

As shown in Figure 4, paper guide 8C, 9C are set to insert, so that the end of upstream one side of the paper of being placed on the placing plate 2B of the allocation position of the end of downstream one side than the paper feeder 1B adjacent with downstream one side is near downstream one side.Paper guide 8B, the 9B of paper feeder 1B are too.

Therefore, when paper guide 8B, 8C, the 9B of paper feeder 1B, 1C, 9C is inserted into paper feeder 1A, the 1B adjacent with downstream one side, paper in transmitting can be directed in the paper of the placing plate 2A, the 2B that are placed on paper feeder 1A, 1B by the surface of last paper, rather than the end of upstream one side of this paper.

So, can prevent to abut to the paper of the placing plate 2A, the 2B that are placed on paper feeder 1A, the 1B adjacent end by upstream one side of last paper with downstream one side from the paper that paper feeder 1B, 1C provide.Thereby the paper in transmitting can not tilt to transmit, and can successfully carry out the transmission of paper.This transmission distance for the paper among paper feeder 1A, 1B, the 1C is unusual actv. when longer.

When transmission is placed on paper on the placing plate 2C of paper feeder 1C, at first under the state that stops each roller 3C-6C rotation shown in Fig. 5 A, utilize not shown actuating device shown in Fig. 5 B, to drive pick-up roller 3C rotation, it is moved down, abut to the plurality of sheets of paper that is placed on the placing plate 2C open in by the surface of last paper SC.And, carry out to the actuating device of the mobile utilization driving pick-up roller 3C of pick-up roller 9C below rotation.

And, rotation by pick-up roller 3C, intake roller 4C begins rotation by endless belt 20C, utilizes with the different not shown actuating device of actuating device that drives pick-up roller 3C and makes reverse roll 5C rotation, and its rotation is with opposite with the hand of rotation of the holding part of intake roller 4C.

The paper SC that abuts to pick-up roller 3C passes out to intake roller 4C and reverse roll 5C shown in Fig. 5 C.

Paper SC is during by the holding part between reverse roll 5C and the intake roller 4C, as shown in Figure 6A, by the rotation of intake roller 4C, when plurality of sheets of paper is opened overlapping transmission, be provided to transfer roller 6C by last paper SC in only plurality of sheets of paper being opened, other paper turn back to placing plate 2C by the rotation of reverse roll 5C.

After the separation of paper SC finishes, in order to improve the conveying capacity of the paper SC that delivers to transfer roller 6C, shown in Fig. 6 B, make reverse roll 5C with the holding part of intake roller 4C in rotate in the same direction with intake roller 4C.

At this moment, because not rotation of transfer roller 6C, the end of downstream one side of paper SC abuts to transfer roller 6C, and under near the state crooked end of the downstream of paper SC one side, end integral body abuts to transfer roller 6C.

Afterwards, shown in Fig. 6 C, begin to stop the rotation of pick-up roller 3C, make it to leave on the placing plate 2C by last paper to through behind the specific time from rotation.Along with stopping of the rotation of pick-up roller 3C, also stop the rotation of intake roller 4C, and stop the rotation of reverse roll 5C.Afterwards, the rotation of beginning transfer roller 6C begins the transmission of paper SC once more.

Why paper SC temporarily being abutted to transfer roller 6C at this, is to transmit for the inclination of correcting paper SC.For example, when paper SC tilted to be sent to transfer roller 6C, at first, the part of the end of downstream one side of paper SC abutted to transfer roller 6C.Afterwards, further send paper SC by pick-up roller 9C etc., therefore in the top ends of the direction of transfer of paper SC, near the beginning bending part of initial and transfer roller 6C butt, and other parts begin to abut to transfer roller 6C.Afterwards, the end of downstream one side of paper SC all finally abuts to transfer roller 6C.

By rotation transfer roller 6C, the end of downstream one side of paper SC all is transmitted by the holding part of transfer roller 6C simultaneously under the state shown in Fig. 6 A, 6B, the 6C.At this moment, the end of upstream one side of paper SC is by after the transfer roller 6C, and for the inclination of correcting the paper SC that the next one should transmit transmits, the rotation that stops transfer roller 6C makes it standby.

Under the situation that has the next paper SC that should transmit, when detecting the end of downstream one side of the paper SC that is now transmitting by being arranged on sensor 120 on the transfer path F1, begin the rotation of pick-up roller 3C of stopping the rotation etc. once more, begin the transmission of next paper SC.

Sensor 120 is configured in the position of transmitting beginning, so that the next paper SC that should transmit is corresponding with the transfer printing sequential of toner image to the transmission of resistance roller 111.In addition, faster than forming electrostatic latent image, toner image in photosensitive drums 105 and being transferred to time of the image forming course on the paper SC from beginning to transmit paper SC to the delivery time that arrives till the resistance roller 111, so the transmission of paper SC can not be later than the transfer printing sequential of the toner image under the transfer position.

And, delivery time from paper feeder 1A to resistance roller 111 weak point of comparing for example with from paper feeder 1C to the delivery time of resistance roller 111, even it is faster than the sequential that is sent to transfer position that paper is sent to the sequential of resistance roller 111, owing in resistance roller 111, can suitably adjust to the transmission sequential of transfer position, so can not have problems.

By carrying out above-mentioned action repeatedly, when the paper SC that is placed on the placing plate 2C of paper feeder 1C is sent to image processing system 100 continuously, can keep the paper of appropriateness to transmit at interval by simple structure, can carry out stable paper and transmit.

And pick-up roller 3A, 3B, 3C begin rotation and through behind the specified time, rotate transfer roller 6A, 6B, 6C, and will be sent to image processing system 100 by the paper that pick-up roller 3A, 3B, 3C send, thereby the inclination that can correct paper transmits.

And the above-mentioned schedule time is meant, begins the transmission of paper SC from pick-up roller 3C, the time till the state that all abuts to transfer roller 6C on the top of paper SC direction of transfer.

So, paper feeder 1A, 1B, 1C are configured to side by side under the structure of side of image processing system 100, also can therefore can stably carry out paper and transmit in tilt when transfer roller 6A, the 6B by each paper feeder 1A, 1B, 1C, the 6C correction of transmission of paper at every turn.

Then, utilize Fig. 7 and Fig. 8 that the action as the lift system 15B of the above-mentioned paper feeder 1B of lifting mechanism of the present invention is described.Image processing system 100 when mono-paper feeder 1B transmits paper, shown in Fig. 7 A, is utilized lift system 15B lifting placing plate 2B, make in the paper that is housed in placing plate 2B height and position move to position α by last paper SB surface.

Afterwards, pick-up roller 3B is descended, by the transmission of rotation beginning paper SB.

Position alpha is: the upper point of the paper SB straight-line pass guide member 11B that will provide by pick-up roller 3B, and can be sent to the upper limit height and position of intake roller 4B and reverse roll 5B smoothly.

Afterwards, carry out paper feeding continuously after, among the placing plate 2B the height and position by last paper SB slowly descend.When this height and position arrives position β shown in Fig. 7 B, arrived by not shown sensor.Lift system 15B rises placing plate 2B according to the detection signal of sensor, makes and leans on the height and position of last paper SB to move to position α most.

Position β is: the rate of curving that effectively utilizes guide member 11B will can be sent to the lower limit height and position of intake roller 4B and reverse roll 5B smoothly by the paper SB of pick-up roller 3B paper feeding.

Therefore, be the scope that can transmit paper SB between position alpha and the position β, be predetermined transmission scope A of the present invention.The difference of the height and position of position alpha and position β generally is set at 30-50 and opens paper thickness.When the height of position β reduced, the paper transfer capability of the pick-up roller 3B of position β descended, and the paper transfer rate takes place postpone, and therefore can stop up owing to time lag causes to transmit.

In structure shown in Figure 3, even image processing system 100 do not carry out that image forms and during standby, and carry out image and form also not under the situation of paper feeder 1A, 1B, paper feeder 1A, 1B, 1C standby such as when 1C transmits paper, shown in Fig. 8 A, lean on the height and position on the surface of last paper SA, SB, SC to be positioned at position alpha among placing plate 2A, the 2B of each paper feeder 1A, 1B, 1C, the 2C most.

When for example transmitting paper SC to image processing system 100, to the same shown in Fig. 8 B, utilize lift system 15B to make the height and position on the surface of the paper SB among the paper feeder 1B drop to position β from the state shown in Fig. 8 A from paper feeder 1C.And the height and position on the paper SA surface among the paper feeder 1A also utilizes lift system 15A to drop to position β.

Afterwards, descend and rotation pick-up roller 3C begins to send by last paper SC being placed in the paper of placing plate 2 of paper feeder 1C.At this moment, make and to clamp with the pick-up roller 3B of predetermined sequential decline paper feeder 1B and the paper SC that sends.

Then, utilize lift system 15B that the placing plate 2B of paper feeder 1B is risen, make the height and position of the paper SC of transmission rise to position alpha.Afterwards, begin to rotate pick-up roller 3B etc., and begin paper SC is sent paper SC from paper feeder 1A.At this moment, make clamp with the pick-up roller 3A of predetermined sequential decline paper feeder 1A and the paper SC that sends after, begin rotation immediately, paper SC is sent to transfer path F3.

At this moment, in paper feeder 1A, also can make the height and position of the paper SC that sends rise to position alpha.Even do not make height and position rise to position alpha, paper SC also is sent to the transfer path F3 of image processing system from paper feeder 1A.And,, also in transfer path F3, be directed even paper SC tilts to transmit a little.Therefore, obstruction etc. can not take place to transmit.

As mentioned above, during from paper feeder 1C transmission paper SC, by the height and position that is lower than the surface of paper SC on the placing plate 2A, the 2B that make the paper feeder 1A, the 1B that are positioned at downstream one side, can prevent that paper SC that sends from paper feeder 1C and the paper that is housed in paper feeder 1A, 1B from clashing by the height and position on the surface of last paper SA, SB.So, the generation of obstruction can be prevented to transmit, thereby paper SC can be transmitted effectively.

In addition, during from paper feeder 1B transmission paper SB, by the height and position that is lower than the surface of paper SB on the placing plate 2A that makes the paper feeder 1A that is positioned at downstream one side, can prevent that paper SB that sends from paper feeder 1B and the paper that is housed in paper feeder 1A from clashing by the height and position on the surface of last paper SA.So, the generation of obstruction can be prevented to transmit, thereby paper SB can be transmitted effectively.

And, because and image processing system 100 is on paper conveyance direction side by side among each paper feeder 1A of configuration, 1B, the 1C, the height and position by the surface of last paper SA, SB, SC can suitably be shifted, the height and position that therefore need not to make paper SA, SB, SC along with near image processing system 100 and fixed order on lower position.So, paper feeder 1A, 1B, 1C can be mutual identical structures.

And, make the mechanism of surface elevation displacement of paper SA, the SB of each paper feeder 1A, 1B when transmitting as paper SB, SC, used according to the amount of accommodating of paper and lift system 15A, the 15B of lifting placing plate 2A, 2B, therefore need not to add new mechanism, thereby can suppress Cost Growth.

Further, when paper SB, SC transmit, height and position by the paper SB among the paper feeder 1B, the 1C that make upstream one side, SC surface be the transmission scope upper limit position α, to make the height and position on paper SA, SB surface among paper feeder 1A, the 1B of downstream one side be the lower position β of transmission scope, can paper SB, SC be sent to image processing system 100 effectively by the simplest control.

And because the height and position between paper guide 8B, 8C and 9B, the 9C is substantially equal to position alpha, so the straight ahead of paper SB, SC is improved, and can transmit paper SB, SC effectively.

But, when the height and position on paper SB, SC surface among paper feeder 1B, the 1C of upstream one side, and paper feeder 1A, the 1B of downstream one side between the height and position on paper SA, SB surface, formed under the condition of sufficient difference of height, also can make these height and positions is position alpha and position β position in addition.

And the paper that paper feeder 1A, 1B, 1C offer image processing system 100 is not limited only to paper, also can be OHP film etc.

Further, paper feeder 1A, 1B, 1C provide the processing equipment of paper to be not limited only to image processing system 100, also can be suitable for paper feeder 1A, 1B, 1C to the processing equipment that carries out paper process.

Fig. 9 is paper feeder 1001A, 1001B, the 1001C that second embodiment of the present invention relates to.Paper feeder 1001A, 1001B, 1001C are identical structure, therefore at this paper feeder 1001C are described.Paper guide 1008C, the 1009C of paper feeder 1001C are identical in the length of paper SC direction of transfer.

During the receiving element 1010B of paper guide 1008C, 1009C the is inserted into paper feeder 1001B adjacent with the downstream of paper feeder 1001C, the top ends of downstream one side be configured in than in the paper on the placing plate 1002B that is placed on paper feeder 1001B by the surface of last paper SB by last and than position, the end of upstream one side of paper SB near downstream one side.

So, the paper SC that sends from paper feeder 1001C can not conflict with the paper that is housed in other the paper feeder 1001Bs adjacent with the downstream, can successfully be sent to the surface of the paper SB that is housed in paper feed unit 1001B.

Other structures among paper feeder 1001A, 1001B, the 1001C are the same with paper feeder 1A, 1B, 1C in first embodiment.

Shown in Figure 10 A, among paper guide 1008C, the 1009C, the part of upstream one side of paper SC direction of transfer is formed flatly in the transmission width M of paper SC at least, and crooked on the direction that can not intersect vertically at direction of transfer with paper SC.

Shown in Figure 10 B, among paper guide 1008C, the 1009C, the part of downstream one side of the direction of transfer of paper SC, on the direction that the direction of transfer with paper SC intersects vertically, central portion forms crooked shape to lower process.

Shown in Figure 10 B, 10C and the bending on the direction that intersects vertically of the direction of transfer of the paper SC of paper guide 1008C, 1009C be: the closer to the downstream one lateral bending Qu Yueda of the direction of transfer of paper SC, one lateral bending Qu Yuexiao the closer to the upstream.

Shown in Figure 11 A, among paper guide 1008C, the 1009C, in the part of the upstream of paper SC direction of transfer one side, paper SC can be crooked on the direction that intersects vertically with direction of transfer, and be transmitted with smooth state.And, shown in Figure 11 B, though paper guide 1008C, 1009C are slightly crooked, between paper guide 1008C and the paper guide 1009C because interval with regulation, so paper SC is crooked hardly.

Shown in Figure 11 C, among paper guide 1008C, the 1009C, in the part of the downstream of direction of transfer one side, paper SC is along the shape of paper guide 1008C, 1009C, and the state with bending on the direction that intersects vertically with direction of transfer transmits.And, shown in Figure 11 D, the leading section that rearward end is positioned at the paper SC under the state of paper guide 1008C, 1009C is owing to waist appears in the bending of rearward end, is transmitted under the state of lower process bending at the central portion that intersects vertically on the direction with direction of transfer.

Therefore, shown in Figure 12 A, the leading section that has passed through the paper SC of paper guide 1008C, 1009C is transmitting under the following state: have only the central portion on the direction that intersects vertically with direction of transfer, touch the surface of the paper SC on the placing plate 1002B that is housed in the paper feeder 1001B adjacent with downstream one side.

In addition, shown in Figure 12 B, in the leading section of paper SC with the pick-up roller 1003B butt of paper feeder 1001B, and the central portion of the direction that intersects vertically of direction of transfer near, on the position of the pick-up roller 1003B butt of paper feeder 1001B, on the direction that intersects vertically with direction of transfer, be smooth state.

The leading section that has passed through the paper SC of paper guide 1008C, 1009C can not touch the surface of the paper SB that is housed among the paper feed unit 1001B at once, and paper SC is crooked on the direction that intersects vertically with direction of transfer, is transmitted under the surperficial state of contact of central portion on the direction and paper SB having only to intersect vertically with direction of transfer.Consequently, the friction drag the when surface of the paper SB under paper SC and the state of accommodating contacts diminishes, and can prevent that the inclination of paper SC from transmitting and transmitting the generation of stopping up.

And and the bending on the direction that intersects vertically of the direction of transfer of paper guide 1008C, 1009C is more little by upstream one side more because its downstream one side the closer to direction of transfer is big more, so can make paper SC successfully crooked.

Further, the part of upstream one side of direction of transfer is formed flatly on the direction that intersects vertically with direction of transfer among paper guide 1008C, the 1009C, can prevent that therefore the transmission that begins the paper SC the transfer path RC till paper guide 1008C, the 1009C from placing plate 1002C from stopping up.

And paper guide 1008A, the 1009A of the paper feeder 1001A adjacent with image processing system 100 also can use under folding state.In this case, paper guide 1008B, 1009B, 1008C, the 1009C of paper guide 100SA, 1009A and other paper feeders 1001B, 1001C are the same, its formation can be crooked on the direction that intersects vertically with paper conveyance direction, also can be and each paper feeder 1001A, 1001B, the identical structure of 1001C.

Figure 14 is the diagram of circuit that the image of the placing plate 2002B that had of the related paper feeder 2001B of the 3rd embodiment of the present invention shown in Figure 13 forms the mobile step outside the action.And therefore paper feeder 2001B shown in Figure 13 omits its explanation because it has identical structure with paper feeder 1B shown in Figure 1.In the action beyond image forms action, judge at first whether paper is placed into (S1) among the placing plate 2002B.For example, use known optical sensor to have or not paper by the light quantity detection with illumination part and light accepting part as sheet detecting apparatus of the present invention.

In S1 when judging when having placed paper, judge to lean on the height and position of last paper SB whether to be within the predetermined transmission scope A (S2) in the paper of placing most, and carry out the processing (S3) of mobile placing plate 2002B repeatedly, in the transmission scope A that the height and position arrival of paper SB is stipulated.Afterwards, in S2, when judging that it is in the predetermined transmission scope A, turn back to the processing of S1.Predetermined transmission scope A is the scope between above-mentioned upper limit position α and the lower position β.

On the other hand, judge in S1 when not placing paper whether that judges placing plate 2002B toply is positioned at predetermined supplementary view B (S4).When being positioned at predetermined supplementary view B above the judgement placing plate 2002B, for example in the read out instrument that paper feeder 2001B is had, urge the demonstration (S5) that replenishes paper.Then, use optical sensor to judge and have or not paper to replenish (S6), till replenishing paper, carry out the processing of S5 repeatedly.

And, when in S4, above judging placing plate 2002B, not being positioned at predetermined supplementary view B,, arrive the supplementary view B that is scheduled to up to it to placing plate 2002B processings (S7) that descend.So, when paper was not placed on the placing plate, the top of placing plate 2002B was positioned at predetermined supplementary view B in advance, so can place paper immediately, and the user need not to wait for that placing plate 2002B moves to predetermined supplementary view B.

On the other hand, in S6, judge when having replenished paper, carry out the processing of S2.And above-mentioned control is carried out with control unit by the not shown paper feeder that paper feeder 2001B has.Paper feeder is controlled all actions of paper feeder 2001B with control unit.And, but paper feeder is connected with the control unit free communication ground of image processing system with control unit.In addition, also the paper feeder control unit can be set, and in the control unit of image processing system 100, paper feeder 1 be carried out integrated control by communication agencies such as networks.The action that control unit control setup that image processing system 100 is had 100 is all.

Figure 16 and Figure 17 are the diagram of circuits with image processing system 100 paper feeding treatment step when image forms action of three paper feeder 2001A, 2001B shown in Figure 15,2001C.At first, by receiving image from the user when forming request with image processing system 100 bonded assembly networks etc., according to forming the number of request reception simultaneously, the information of view data etc., any one (S11) among the paper feeding box 102,103 of setting request paper feeding, paper feeder 2001A, 2001B, the 2001C with image.

That then, judge that the paper feeding request sets is which (S12) among paper feeder 2001A, 2001B, the 2001C.When in having judged paper feeder 2001A, 2001B, 2001C which set the paper feeding request, advance to the processing of S21.

And, setting when judgement paper feeding request among the S12 is not paper feeder 2001A, 2001B, 2001C, and when being arranged on paper feeding box 102 grades in the image processing system 100, when for example judging, judge whether accommodated paper (S13) in the paper feeding box 102 from 102 paper feedings of paper feeding box.

In S13, judge when paper has been housed in paper feeding box 102 that the beginning image forms handles (S14), from 102 paper feedings of paper feeding box.

Afterwards, further judge whether paper S is carried out image formation place (S15), continue to carry out turning back to when image forms processing S13 to new paper when judging.And, in S15, do not continue when new paper carries out image formation processing, to finish image and form action when judging.

On the other hand, in S13, when in judging paper feeding box 102, not accommodating paper, in the display unit that image processing system 100 has, urge the paper that replenishes paper to replenish and handle (S16).Then judge whether and to substitute and carry out image and form (S17) with being housed in paper in other paper feeding boxes 103,, set paper feeding box 103 grades (S18) of asking paper feeding, and turn back to S13 when being judged as to substitute the time.

On the other hand, in S17, judge and to judge whether and to substitute (S19) with the paper that is housed in paper feeder 2001A, 2001B, 2001C with being housed in paper in other paper feeding boxes 103 when substituting.When being judged as can substitute the time, set 2001A, 2001B, the 2001C (S20) of request paper feeding, carry out the processing of S21.

And in S19, when judgement can't substitute with the paper that is housed in paper feeder 2001A, 2001B, 2001C, turn back to the processing of S13.

Then, as shown in figure 17 in S21, output contains the paper feeding request signal of customizing messages, and above-mentioned customizing messages is which of paper feeder 2001A, 2001B, 2001C of all paper feeder 2001A, 2001B of configuration, 2001C being determined the request paper feeding.This is because all paper feeder 2001A, 2001B, 2001C have been begun to be used for the processing of paper feeding according to the paper feeding request signal that receives.

For example, when the paper feeding request is carried out at paper feeder 2001B, judge among the paper feeder 2001B that sets whether accommodated paper (S22), when paper has been accommodated in judgement, judge whether to have formed transfer path RA, RB, RC (823).

Why judge whether to have formed transfer path RA, RB, RC at this, be because transfer path RA, RB, RC be by in the paper that is placed on placing plate 2002A, 2002B, 2002C by the surface of last paper SA, SB, SC or do not place placing plate 2002A, the 2002B of paper, the surface of 2002C forms.

Promptly, during from paper feeder 2001C transmission paper SC, through in the paper of placing plate 2002B that being placed on paper feeder 2001B by last paper SB surface or do not place paper placing plate 2002B the surface and be placed in the paper of placing plate 2002A of paper feeder 2001A by last paper SA surface or the surface of not placing the placing plate 2002A of paper, and be sent to image processing system 100.And, when paper feeder 2001B transmits paper SB, through in the paper of the placing plate 2002A that being placed on paper feeder 2001A by last paper SA surface or do not place paper placing plate 2002A the surface and be sent to image processing system 100.

In S23, the judgement that whether forms transfer path RA, RB, RC is for example undertaken by receiving the signal that is ready to complete from paper feeder 2001A, 2001B, the paper of 2001C output.

When judgement has formed transfer path RA, RB, RC, begin image and form processing (S24) in S23, this image forms processing and comprises that the paper feeding that will begin paper feeding begins request signal and sends to paper feeder 2001B etc.Afterwards, judge whether to continue to carry out image and form processing (S25), when image formation is proceeded in judgement, turn back to the processing of S22 to new paper.And, when judging that in S25 not proceeding image forms, form end signal to each paper feeder 2001A, 2001B, 2001C output image, finish image and form action.

On the other hand, in S23, when judgement does not form transfer path RA, RB, RC, the processing (S27) of till forming, exporting the paper feeding request signal repeatedly.

And, in S22, when in judging the paper feeder 2001B that sets, not accommodating paper, judge whether and can substitute (S28) with being housed in the paper of accommodating among other paper feeders 2001A, the 2001C.When judgement can substitute with the paper of other paper feeders 2001A, 2001C, make this paper feeder 2001A, 2001C be set at paper feeding and use (S29), and return the processing of S21.

On the other hand, when judgement cannot substitute with the paper of other paper feeders 2001A, 2001C, can judgement substitute (S30) with the paper of being accommodated in paper feeding box 102 grades that are configured in image processing system 100.

In S30, can be with being configured in the paper of being accommodated in paper feeding box 102 grades when substituting when judging, the signal (S32) that the paper feeding among the output paper feeder 2001B finishes is set at paper feeding with (S33) with these paper feeding box 102 grades, and turns back to the processing of S13.

And, in S30, can't be with being configured in the paper of being accommodated in paper feeding box 102 grades when substituting when judging, form the signal (S31) of action to the paper feeder 2001B output interrupt images of setting, turn back to S21.Therefore, till replenishing paper, processing is interrupted.

Figure 18 and Figure 19 are the diagram of circuits of the paper feeding step of paper feeder 2001B when receiving the paper feeding request signal.When paper feeder 2001B receives the paper feeding request signal from image processing system 100, that at first judge paper feeding is oneself paper feeder 2001B or other paper feeders 2001A, 2001C (S40), when judgement is the paper feeding of paper feeder 2001B of oneself, use optical sensor to judge whether placed paper (S41) among the placing plate 2002B.

When in S41, judging placing plate 2002B, having placed paper, the signal output that has paper to image processing system 100 (S42), is turned back to the processing of S51.And when judgement was not placed paper in placing plate S2, there was not the signal (S44) of paper in output in S41.

Afterwards, in S45, judge from image processing system 100 whether receive the signal that interrupt images forms, when judgement has received, placing plate 2002B is dropped to predetermined supplementary view B (S46).And, urge additional demonstration (S47) by the read out instrument that is configured on the paper feeder 2001B.

Then, judge whether paper has been placed into placing plate 2002B and has gone up (S48), and keep standby until having placed paper.In S48, judge when on placing plate 2002B, having placed paper, advance to the processing of S42.

On the other hand, when in S45, judging the signal that does not receive interrupt images formation, judged whether to receive new paper feeding request signal (S49).This is to substitute with the paper of being accommodated among other paper feeders 2001A, the 2001C because judge whether.When judgement has received the paper feeding request signal, begin to be housed in the transmission of the paper among other paper feeders 2001A, the 2001C, and return the processing of S40.

And, in S49, judge whether to have received paper feeding end signal (S50) when not receiving the paper feeding request signal when judging, when being judged as when having received, finish the paper feeding action.And, in S50,, carry out S45,49,50 processing repeatedly, up to receiving any one signal when judging when not receiving the paper feeding end signal.

In S51, whether the last paper SB that leans on most that judges the paper that is placed on the placing plate 2002B is in the predetermined transmission scope A, when judgement is not in the predetermined delivering position A, make placing plate 2002B lifting (S52), move in the predetermined transmission scope A up to it.

On the other hand, in S51, when judgement be placed on paper among the placing plate 2002B be in the predetermined transmission scope A by the height and position of last paper SB the time, prepare the content (S53) that finishes to image processing system output paper feeding.

Then, judge whether to receive paper feeding and begin request signal (S54), when judgement does not receive, carry out the processing of S54 repeatedly, till receiving signal.And when judgement has received paper feeding when beginning request signal, (S55) handled in the paper feeding that begins to rotate pick-up roller 2003B etc.

Afterwards, judged whether to receive and continued new paper feeding and begin request signal (S56),, carried out the paper feeding of S55 repeatedly and handle when being judged as when having received, when not asking till.And, in S56, when judging that not receiving paper feeding begins request signal, finish the paper feeding action.

On the other hand, in S40, judge whether to carry out from being configured in the paper feeder 200C paper feeding (S57) of upstream one side when being paper feeding from other paper feeders 2001A, 200C when judging.When being judged as when being configured in the paper feeder 200C paper feeding of upstream one side, judge in the paper that is placed on placing plate 2002B by the height and position on last paper SB surface or when not placing paper in the placing plate 2002B height and position on placing plate 2002B surface whether be in predetermined transmission scope A with interior (S58).That is, judge whether to have formed transfer path RA, the RB that is used to transmit paper, the part of RC.

And, in S57,, finish the paper feeding action when being judged as when being configured in the paper feeder 2001A paper feeding of downstream one side.

In S58, when the height and position on the height and position of judging paper SB surface or placing plate 2002B surface is not in the predetermined transmission scope A, carry out the processing (S59) of mobile placing plate 2002B repeatedly, arrive in the transmission scope A of regulation up to it.And, in S58, when the height and position on the height and position of judging paper SB surface or placing plate 2002B surface is in the predetermined transmission scope A, prepare the signal (S60) of end to image processing system 100 output paper feedings.

Then, judge that in S61 image forms action and whether finishes.This judgement is for example undertaken by the signal that whether has received new request paper feeding.Only do not carry out the processing of S61 repeatedly up to receiving.That is, till forming release, image keeps present situation.

As mentioned above, transmit from the paper feeder 2001C that is configured in paper feeder 2001B upstream one side paper during in, the surface elevation position of placing plate 2002B is in the predetermined transmission scope A when leaning on most the surface elevation position of last paper SB in the paper that is placed on placing plate 2002B or not placing paper by making, when even paper is not placed into placing plate 2002B, the transmission that also can prevent the paper that sends from other paper feeders 2001C that is configured in upstream one side is stopped up, and can transmit paper rightly.And, in paper feeder 2001A, when paper feeder 2001B, the 2001C that is configured in upstream one side transmits paper too.

And, in time beyond during the formation transfer path RB, because make the height and position that leans on the height and position of last paper SB in the paper that is placed on the placing plate 2002B most or do not place the surface of the placing plate 2002B under the paper state move to predetermined supplementary view B, therefore the user can be placed into paper on the placing plate immediately when paper replenishes.

Therefore, can when making paper be easy to place, guarantee the paper conveying function of other paper feeders 2001A, 2001B, 2001C.

In addition, in embodiments of the present invention, as an example, only during paper feeder 2001C transmission paper, the height and position that leans on most the height and position of last paper SB in the paper that is placed on the placing plate 2002B or do not place the surface of the placing plate 2002B under the paper state is in the predetermined transmission scope A, but is not limited in this.For example also can be receive from user's image form till beginning after the request to form action and finish fully to image during.

And, in during beyond when paper replenishes, the height and position that leans on the height and position of last paper SB in the paper that is placed on the placing plate 2002B most or do not place the surface of the placing plate 2002B under the paper state always is in the predetermined transmission scope A.So, need not to wait for to move to predetermined delivering position A that can begin paper immediately and transmit, the image that therefore also can begin immediately in the image processing system 100 forms processing.

Further, only transmit from the paper feeder 2001C that is configured in upstream one side paper during in, the height and position that leans on most the height and position of last paper SB in the paper that is placed on the placing plate 2002B or do not place the surface of the placing plate 2002B under the paper state is in the predetermined transmission scope A, therefore the part of formation transfer path RB in can be only during needs, thus the travel frequency of placing plate 2002B and paper SB can be suppressed as much as possible.

So, the power consumption of the lift system of lifting placing plate 2002B can be suppressed to drive, and the load that caused along with mobile placing plate 2002B and paper SB can be suppressed lift system.

And, when paper is not placed into placing plate 2002B, use read out instrument to urge the user to carry out replenishing of paper, therefore can suppress not place the continuity of the state of paper, and can suppress the travel frequency of placing plate 2002B.

Followingly the paper feeder 3001 that the 4th embodiment of the present invention relates to is described with reference to accompanying drawing.As shown in figure 20, paper feeder 3001 has a plurality of (being three in the present embodiment) paper feed unit 3001A, 3001B, 3001C.The direction of transfer of paper feed unit 3001A, 3001B, 3001C and paper is configured in side by side as paper being carried out the side that image forms the image processing system 100 of the processing equipment of handling.

Paper feed unit 3001A, 3001B have identical structure with paper feed unit 3001C except height.Paper feed unit 3001B forms: the height of the receiving element 10 of paper feed unit 3001B is identical with the height of the output unit 3007C of paper feed unit 3001C.Paper feed unit 3001A forms: the height of the receiving element 3010A of paper feed unit 3001A is identical with the height of the output unit 3007B of paper feed unit 3001B.

And, paper feed unit 3001A, 3001B, 3001C mounting table 3002A, 3002B, 3002C separately is configured to: the surface of the paper SC that leans on most in more away from the paper on the mounting table 3002C of the paper feed unit 3001C of image processing system 100 is high more, and the surface of the paper SA that leans on most in the paper on the mounting table 3002A of the paper feeding box 3001A of image processing system 100 is low more.And the paper guide 3008A of the paper feed unit 3001A adjacent, the paper receiving unit 114 that 3009A is inserted into image processing system 100 with image processing system 100.

Paper feed unit 3001A, the 3001B of above-mentioned formation, 3001C are configured in the side of image processing system 100 side by side.Paper feed unit 3001A forms than manually dish 113 is low, thus not interfering picture form device 100 manual dish 113 and directly to paper receiving unit 114 paper supplies of image processing system 100.In addition, below mainly the relation of paper feed unit 3001B and paper feed unit 3001C is described, the relation of paper feed unit 3001A and paper feed unit 3001B also is the same.Paper is direction transmission left in Figure 21.

Paper feed unit 3001B, 3001C be configuration laterally side by side, so that it is relative with the output unit 3007C of the paper feed unit 3001C that is configured in upstream one side to be configured in the receiving element 3010B of paper feed unit 3001B of paper conveyance direction middle and lower reaches one side.The receiving element 3010A of the paper guide 3008B of paper feed unit 3001B, 3009B the is inserted into paper feed unit 3001A adjacent with downstream one side.The receiving element 3010B of the paper guide 3008C of paper feed unit 3001C, 3009C the is inserted into paper feed unit 3001B adjacent with downstream one side.So, be communicated with paper feed unit 3001A, transfer path RA, the RB of 3001B, 3001C, RC.

Figure 22 is the partial enlarged drawing of paper feeder 3001.During receiving element 3010B that the paper guide 3008C of paper feed unit 3001C, 3009C are inserted into paper feed unit 3001B, downstream one side top ends P be configured in than in the paper on the placing plate 3002B that is placed on paper feed unit 3001B by the surface of last paper SB by last and than the end Q of upstream one side of paper SB position near downstream one side.So, the paper SC that sends from paper feeder 3001C not can with the paper conflict that is housed in paper feed unit 3001B, can successfully be sent to surface by last paper SB.

As shown in figure 20, the distance L 1 between the transfer roller 3006C of the pick-up roller 3003B of paper feed unit 3001B and paper feed unit 3001C is set shortlyer than the size L2 of the direction of transfer of the paper that transmits.For example, pick-up roller 3003C is arranged on apart from the position that is configured in leading section 50mm-60mm and surperficial butt paper SC that depends on last paper SC most on the placing plate 3002C.So, the transfer roller 3006C of paper SC by paper feed unit 3001C be transmitted during in, the pick-up roller 3003B by paper feed unit 3001B is transmitted.Therefore, when transmitting paper, can not interrupt, suppress to transmit and stopped up the conveying capacity of paper through paper feed unit 3001B, 3001C.

The paper SC that is sent to paper feed unit 3001B from paper feed unit 3001C is directed and is sent to the surface of depending on last paper SB in the paper feed unit 3001B most.That is, the surface of paper SB constitutes the part of transfer path RB.In addition, when not having paper on the placing plate 3002, the paper SC in the transmission is directed and is sent to the surface of placing plate 3002B.At this moment, the surface of placing plate 3002 constitutes the part of transfer path RB.

The propulsive effort of transfer roller 3006C by paper feed unit 3001C, the paper SC that transmits on the surface of the paper SB that leans on most in the paper on being placed on the placing plate 3002B of paper feed unit 3001B during by the transfer roller 3006C clamping of paper feed unit 3001C in, pick-up roller 3003B by the paper feed unit 3001B that descends with scheduled timing is transmitted, and further the transfer roller 3006B by paper feed unit 3001B is sent to downstream one side.

As mentioned above, in the paper feeder 3001 that the present invention relates to, be housed in paper among the paper feed unit 3001C successively through the transfer path RC of paper feed unit 3001C and be configured in transfer path RB, the RA of paper feed unit 3001B, the 1A of paper feed unit 3001C downstream one side, be sent to image processing system 100.That is, be housed in paper feed unit 3001A, 3001B paper transmission and be configured in the transfer path RA that uses paper feed unit 3001A, 3001B than the transmission of the paper of being accommodated among paper feed unit 3001A, 3001B paper feed unit 3001B, the 3001C jointly near upstream one side.

Paper feeder 3001 set, the paper of the closer to the paper feed unit 3001A that be configured in downstream one side in being accommodated the highest more the lowest more of the paper of being accommodated in the paper feed unit 3001C of upstream one side that is configured in paper conveyance direction by upper surface by upper surface, therefore the conflict of paper can not take place, the paper that then paper feed unit 3001C sends from the upstream be sent to the paper feed unit 3001B that is housed in downstream one side by the upper surface of last paper SB, afterwards, while the surface by paper SB is directed successfully being sent to downstream one side.

And according to paper feeder 3001, paper can be not crooked on direction of transfer, do not have the N/R bending in the paper that sends, and the inclination that therefore can suppress paper transmits and transmits and stop up.And, constituted the part of transfer path RA, RB by the surface of last paper SA, SB, therefore need not be in prior art the individual settings transfer path, can make paper feeder 3001 miniaturizations.

Further, owing to output unit 3007B, 3007C are communicated with receiving element 3010A, 3010B respectively, thereby can connect each transfer path RA, RB, the RC of a plurality of paper feed unit 3001A, 3001B, 3001C.

And, owing among output unit 3007B, the 3007C paper guide 3008B, 3009B, 3008C, 3009C are set, therefore the paper from output unit 3007B, 3007C output can be directed to transfer path RA, RB smoothly, and further suppress to transmit to stop up.

Further, paper be transmitted roller 3006B, 3006C clamping during in picked roller 3003A, 3003B clamping, so the paper conveying capacity can not interrupt, and can suppress to transmit and stop up.

And when the paper that should be provided to image processing system 100 took place to transmit obstruction, in the transfer printing unit of image processing system 100, toner was attached in the transfer device 109, in subsequent processing the bad problem of transfer printing can take place.And, reclaim though be transferred to the cleaning unit 110 that the not photographic fixing toner of paper is not configured in around the photosensitive drums 105, when the amount of toner was big, the load of cleaning unit 110 became greatly.Further, also become the not photographic fixing toner that is not transferred to paper reason in the device interior diffusion.As mentioned above, transmit when stopping up when paper takes place, the transfer printing load bad, cleaning unit 110 that can produce image processing system 100 increases, toner is in a lot of problems such as device interior expansions, and the required cost of one page paper printing increases.Relative with it, according to paper feeder 3001, transmit obstruction owing to can suppress paper, therefore can suppress the generation of the problems referred to above, reduction a piece of paper is opened the printshop needs cost.

And, in the above-described embodiment, the top ends P of downstream one side of paper guide 3008C, 3009C be configured in than in the paper on the placing plate 3002B that is placed on paper feed unit 3001B by the surface of last paper SB by on last and the position of end Q near downstream one side than upstream one side of paper SB, but be not limited thereto.

For example as shown in figure 23, the top ends P of downstream one side of paper guide 3008C, 3009C also can be configured in than the surface of the paper SB that is placed on paper feed unit 3001B by on last preliminary dimension M and the position of end Q near the preliminary dimension N of downstream one side than upstream one side of paper SB.

The size M of this moment and size N wait to determine according to paper thickness, size and aqueous ingredients, in most cases size M and size N are about equally, when the top ends of the paper SC that transmits by paper guide 3008C, 3009C is bent downwardly, also can be sent to the upper surface of paper SB.Size M and size N are set at the arbitrary dimension between several mm of several mm-10.

And size M and size N are more little, and the difference of height of each paper feed unit 3001A-3001C is more little.Therefore, as shown in figure 22, the top ends P of downstream one side of paper guide 3008C, 3009C be configured in than the surface of the paper SB that is housed in the paper feed unit 3001B adjacent with downstream one side by last and than the end Q of upstream one side of paper SB near on the position of downstream one side the time, the difference of height that can make each paper feed unit 3001A-3001C suppresses the transmission of paper for minimum the time and stops up.

The paper feeder 4001 that the 5th embodiment of the present invention relates to is connected to the side of image processing system 100 as shown in figure 24 as an example of processing equipment.Image processing system 100 is identical with device shown in Figure 3.

The paper that provides unit 4001B to provide, received by receiving element 4010 by the paper of upstream one side is directed and is sent on the placing plate 4002A the surface by last paper SA.That is, being placed in the paper on the placing plate 4002A surface by last paper SA constitutes and connects the part that image processing system 100 and each paper provide the transfer path between unit 4001A, 4001B, the 4001C.

The propulsive effort of the transfer roller 4006B of unit 4001B is provided by paper, along be placed on paper provide in the paper on the placing plate 4002A of unit 4001A the paper SB that transmits by the surface of last paper SA be transmitted roller 4006B clamping during in, be held by its top ends of pick-up roller 4003A that descends with predetermined sequential, and be transmitted by pick-up roller 4003A.Further, paper SB provides the transfer roller 4006A of unit 4001A further to be sent to downstream one side by paper.

As mentioned above, in the paper feeder 4001 that the present invention relates to, be housed in paper that paper provides unit 4001B through paper provide unit 4001B transfer path RB, and paper the transfer path RA of unit 4001A is provided, be sent to image processing system 100.That is, the paper of downstream one side provides the transfer path RA of unit 4001A to be respectively applied for to transmit and is housed in paper when the paper of unit 4001A is provided, and transmits and be housed in paper when the paper of unit 4001B, 4001C is provided.

Paper provides unit 4001A and image processing system 100 disposed adjacent, makes that the paper receiving unit 114 of output unit 4007A and image processing system 100 is relative.Be housed in paper that paper provides unit 4001A, 4001B, 4001C and be sent to transfer position by paper transport path F3 from the paper receiving unit 114 of image processing system 100.For example, be housed in paper that paper provides unit 4001C through paper provide transfer path RB that transfer path RC, the paper of unit 4001C provide unit 4001B, and paper the transfer path RA of unit 4001A is provided, and paper receiving unit 114, the paper transport path F3 of process image processing system 100, be sent to transfer position.

According to paper feeder 4001, when image processing system 100 is provided with a plurality of paper unit 4001A, 4001B, 4001C are provided, can distinguish in the horizontal direction configuration side by side, so transfer path RA, the RB of paper, RC can be roughly the straight line shape.Therefore, the paper that transmits on transfer path RA, the RB in paper feeder 1, the RC is not easy to bending, can suppress to transmit and stop up.And paper S can be not crooked, can not generate the N/R waist, is difficult in image processing system 100 that therefore image takes place and forms bad problem.

In paper feeder 4001, owing to be housed in the part that has constituted transfer path RA, RB, RC of paper among placing plate 4002A, 4002B, the 4002C by the surface of last paper SA, SB, SC, therefore need not to form in addition transfer path, can make paper feeder 4001 miniaturizations.

And the paper that processing equipment was accommodated and be provided to paper feeder 4001 is not limited only to paper, also can be OHP film etc.Paper feeder 4001 provides the processing equipment of paper to be not limited to image processing system, also can be that device beyond the image processing system such as paper processing device is as main device.

Paper provides unit 4001A, 4001B, 4001C to arrange as shown in figure 28 in paper feeder 4001.Provide among the unit 4001A at paper, the paper of A4 size is vertically placed., vertically be meant on the direction that the paper with Figure 28 intersects vertically the long side direction of configuration paper here.Provide the paper of laterally placing the B4 size among the unit 4001B at paper, paper provides the paper of laterally placing the A3 size in the unit 4001.

In the present embodiment, along with close image processing system 100, the length of the direction of transfer of the paper of accommodating determines that paper provides putting in order of unit 4001A, 4001B, 4001C with diminishing.Therefore no matter when paper provides among unit 4001A, 4001B, the 4001C any one to have paper to provide, also be difficult to take place paper and transmit problem.

Dispose paper as shown in figure 28 unit 4001A, 4001B, 4001C are provided, considering provides unit 4001C to transmit the situation of A3 size sheets from paper.The paper of the A3 size that sends from paper transfer 1C is sent to paper transfer 4001B by paper feeder unit 4007 and receiving element 4010B.The paper that is sent to paper transfer 4001B in-to-in A3 size is sent to downstream one side of direction of transfer along the surface of the paper of the B4 size that is housed in paper transfer 4001B.

The length of the direction of transfer of the B4 size sheets in the paper transfer 4001B is 365mm, and the length of the direction of transfer of the paper of the A3 size of transmission is 420mm.The length of direction of transfer relatively, because the paper of the A3 size that transmits is bigger, so rear end one side is when transmitting by transfer roller 4006C, the top of A3 size sheets arrives pick-up roller 4003B.

Further, the paper of A3 size is sent to paper by paper feeder unit 4007B and receiving element 4010A unit 4001A is provided.It is 210mm that paper provides the length of direction of transfer of the paper of the A4 size in the unit 4001A, littler than the direction of transfer length of the paper of A3 size.Therefore, rear end one side is when transmitting by transfer roller 4006B, and the paper top of A3 size arrives pick-up roller 4003A.

Equally, consider situation when paper generator 4001B transmits the paper of B4 size.After at first beginning to transmit, by paper feeder unit 4007B and receiving element 4010A, the paper of B4 size is sent to paper and provides in the unit 4001A.It is 210mm that paper provides the length of direction of transfer of the paper of the A4 size in the unit 4001A, littler than the length of the direction of transfer of the paper of B4 size.Therefore, when rear end one side transmitted by transfer roller 4006B, the top of the paper of B4 size arrived pick-up roller 4003A.

So, be housed in paper and provide the length of direction of transfer of the paper in unit 4001A, 4001B, the 4001C more little by making the closer to image processing system 100, can effectively utilize the length of direction of transfer of the paper of transmission, preventing that paper from transmitting interrupts and the paper delay.Therefore, can provide the quantity of unit irrelevant, paper is sent to image processing system 100 with the paper of process.

Paper transfer rate V4 in paper transfer rate V3 in paper transfer rate V2, the paper transfer 4001B in the circumferential velocity V1 of resistance roller 111 shown in Figure 29, the paper transfer 4001A, the paper transfer 4001 carries out following setting.

Transfer rate V2 be set at satisfy printing treatment number of pages and paper at interval, the rear end of last paper and transmit the speed that the front end of paper does not clash by resistance roller 111 location the time.Transfer rate V3 be set at satisfy printing treatment number of pages and paper at interval, the rear end of last paper and transmit the speed that the front end of paper does not clash in paper provides unit 4001A.Transfer rate V4 be set at satisfy printing treatment number of pages and paper at interval, the rear end of last paper and transmit the speed that the front end of paper does not clash in paper provides unit 4001B.

And, each transfer rate V1, V2, V3, V4 are set at when comparing each transfer rate V1, V2, V3, V4, have the relation of V1＜V2≤V3≤V4.Why setting like this is for the paper that makes transmission correctly is sent to resistance roller 111, and the printing treatment speed in the image processing system 100 that prevents descends.

The length of paper guide 4009B as shown in figure 30, paper guide 4009B extends to than paper provides the rear end of paper of A4 size of unit 4001A near downstream one side of paper conveyance direction.Equally, paper guide 4009C extends to than paper provides the rear end of paper of B4 size of unit 4001B near downstream one side of paper conveyance direction.Consequently and the waist of paper irrelevant, can successfully carry out the transmission of paper.For example, do not have the paper of waist also can pass through to be supported by paper guide 4009B, 4009C from downside, macrobending ground is sent to downstream one side along paper conveyance direction thereby can not can produce very.

The paper feeder 5001 that the 6th embodiment of the present invention relates to is configured in the side with image processing system shown in Figure 3 100 same apparatus as shown in figure 31.The main portion of image processing system 100 and paper feeder 5001 and image processing system shown in Figure 25 100 and paper feeder 4001 have same structure.And the paper of paper feeder 5001 provides unit 5001A, 5001B, 5001C to provide unit 4001B to have identical structure with paper shown in Figure 25 respectively.
