As shown in the figure, the volute spring 4 that is connected on the pressing component 1 is oblique to the 10b of the portion inclination of the baffle plate back side.(with reference to Fig. 6 A) compares during with pressing component 1 standby, and the length of volute spring 4 is a little long.Therefore, for volute spring 4, be back to the power effect of Fig. 6 state from the state of Fig. 8.
That is, when be discharged from run into the head 1a of pressing component 1 with paper the time, even, also can rotate and teat is housed in the facial 10a of baffle sheet by pressing component 1 with the small power such as collision of paper (especially piling up) with paper.And, when releasing imposes on pressure on the head 1a, can be by the recuperability of volute spring 4, get back to the head 1a that makes pressing component 1 and 1b once more from the outstanding state (with reference to Fig. 6) of the facial 10a of baffle sheet.
Secondly, push action with reference to Fig. 9～Figure 11 explanation with paper.Fig. 9 is the block diagram that expression is used to control the control system of image processing system 100.In Fig. 9, control circuit 170 is to be used for the control circuit that the control chart picture forms apparatus main body 110, and for example it is made of the microprocessor that comprises CPU, and each several part is controlled in the operation of operation response portion 171, so that form image.
And control circuit 180 is the control circuits that are used to control with sheet post-processing apparatus 120, and for example it is made of the microprocessor that comprises CPU.The control circuit 170 mutual transmission information of control circuit 180 and image processing system main body 110, and control each parts that is used for the paper aftertreatment, so that the action that image forms links with the action of using sheet post-processing apparatus 120.
And control circuit 180 controls make the motor 181 of discharge tray 166 liftings, the motor 183 that is used to drive the motor 182 of baffle plate 10 and is used to drive conveying belt 50.That is, control circuit 180 is configured for controlling the discharge control part of discharging with paper that the discharge tray control part of the lifting of discharge tray 166, the baffle controls portion and being used to that is used to control the lifting of baffle plate 10 are controlled conveying belt 50.
And, the testing result from the first sensor 80 and second sensor 90 can be inputed to control circuit 180.The testing result of the control circuit 180 response first sensors 80 and second sensor 90 makes discharge tray 166 liftings.And control circuit 180 comprises the testing result that responds second sensor 90 and the counter 184 that moves.
Figure 10 A is that discharge tray 166 rises and with near the be pressed stereographic map of discharge tray 166 of the first aftertreatment portion 160 of parts 1 when pushing of the rearward end of paper P.And Figure 10 B is that discharge tray 166 rises and with near the be pressed sectional view of the schematic configuration of the discharge tray 166 of the first aftertreatment portion 160 of parts 1 when pushing of the rearward end of paper P.
That having carried out that classification handles is discharged from sheet feeding/discharge pallet 166 with the paper P or the rotation of piling up by conveying belt 50 with paper of having carried out the bookbinding processing.At this moment, discharge tray 166 with the height (with reference to Fig. 3) of the position of readiness that do not contact pressing component 1 receive be discharged from use paper P.Owing to, breakked away to baffle plate 10 with paper P, and by run into the adjustment of baffle plate 10 usefulness paper throughput directions with the rearward end of paper P by what discharge tray 166 blocked by the inclination that discharge tray 166 is provided with.At this moment, use the rearward end of paper P between discharge tray 166 and pressing component 1.
The motor 182 that is used to drive conveying belt 50 is the stepping motors with the pulse power synchronization action.By not shown counter this driving pulse is counted, when reaching the quantity of regulation counting, control lifting discharge tray 166 or baffle plate 10.Thus, can preferably realize clamping and keep action (clamping action) and the action timing of the action (release movement) that separates with rearward end with the rearward end of paper P.
The sensor 90 that is arranged at discharge tray 166 detects and has been discharged to discharge tray 166 with paper P, and the counter 184 of control circuit 180 begins the counting action.And as shown in figure 10, control circuit 180 rises by making discharge tray 166, clamps the rearward end of using paper P thereby make to pressing component 1 following reinforcing, moving up and down and discharge tray 166.Thus, can remain on paper P that to keep regularity constant with adjusted.
Near the pressing component 1 when Figure 11 A and 11B show discharge tray 166 risings sectional view.Figure 11 A shows the state by the rearward end of pressing component 1 and discharge tray 166 clamping paper P.Figure 11 B shows discharge tray 166 and further rises to the state that touches the height and position of first sensor 80 with the rearward end of paper P.
Because the pressing component 1 to following reinforcing can slide in baffle plate 10, so keeping using under the state of paper P at pressing component 1 and tray surface, discharge tray 166 rises.Rise by pallet, and touch first sensor 80, thereby can detect the top that is loaded on the discharge tray 166 with paper with the rearward end of paper P.This testing result is transfused to control circuit 180.
Follow-up when using paper when discharging, run into paper or sliding contact has been positioned at and uses paper P on the pallet 166 until follow-up by pressing to pallet with the rearward end of the paper P parts 1 that are pressed.Thus, that can suppress follow-up discharge has remained on the paper of using on the pallet with paper sliding contact and jack-up (prominent I Move か The), thereby the skew that takes place etc. destroy the situation of regularity.
When being received by discharge tray 166 and when baffle plate 10 breakked away, discharge tray 166 descended and controls of follow-up discharge, so that follow-uply come between pressing component 1 and the movable discharge tray with paper with paper P with paper.By repeating this a series of action, thus can guarantee to be loaded on the discharge tray 166 with in the regularity of paper, receive new discharge use paper.
And, when discharging when using paper, as shown in Figure 3A, near the height and position of discharge tray 166 first sensor 80 (below be called position of readiness) standby.Along be loaded in discharge tray 166 with the increase of paper, the control that the position of readiness of discharge tray 166 is descended is no more than the height and position (below be called first height and position) of first sensor 80 with the top of using paper.
That is, when paper is used in each discharge, rise once more after discharge tray 166 interim the declines.And, use the paper rearward end when pushing by pressing component 1, when then detecting the upper surface of the usefulness paper on the discharge tray 166 by sensor 80, discharge tray 166 stops on this position, and the upper surface of using paper is always at first height and position.Therefore, before detecting with the paper upper surface, always push the rearward end with paper of being loaded owing to be arranged on the following pressing component 1 of first sensor 80, so can prevent the error-detecting of first sensor 80 by first sensor 80.
Below, the flank spare 20 that is arranged on the Eight characters shape on the discharge tray 166 is described (with reference to Fig. 3).Figure 12 A is the sectional view of the part of presentation graphs 3B.Figure 12 B is the summary construction diagram from part shown in top observation Figure 12 A.
The first aftertreatment portion 160 comprises: discharge portion (outlet roller 30 and output are with 50) is used for usefulness paper P is discharged to discharging direction (black arrow) from escape hole 70; As the baffle plate 10 of wall components, be arranged on below the escape hole 70; Discharge tray 166, what be used to receive discharge uses paper P, has to the break away inclination that falls and rise mobile along baffle plate 10 of baffle plate 10; And as the flank spare 20 of jut, on discharge tray 166, extend from baffle plate 10 lateral row outgoing directions and be provided with, be used for supporting to use paper P, so that the end with baffle plate side opposition side with paper P on the discharge tray 166 has convex bend.
