These pallets (split component) connect each other rotationally.So, when opening loam cake 130, can fold and discharge pallet 200, when closing loam cake 130, can make and discharge pallet 200 extensions.
The upstream extremity of the discharge direction along recording paper of upstream pallet 210 (direction of arrow A) is connected with loam cake 130 rotationally by upstream connecting portion 211 (Figure 11 and Figure 12), and the downstream end of upstream pallet 210 is connected with intermediate tray 220 rotationally by middle interconnecting piece 212 (Fig. 7).
Extremely shown in Figure 13 as Fig. 3 and Figure 11, sheet stacking portion 133 is also as the part of loam cake 130 and the part of discharge pallet 200.Upstream connecting portion 211 is arranged in the downstream of sheet stacking portion 133.Upstream connecting portion 211 (Figure 11 and Figure 12) have from upstream pallet 210 along two of the upstream side of the discharge direction of recording paper side-prominent columnar shafts 213.Axle 213 movably engages with the elongated slot 131 as guide portion that discharge direction along recording paper is formed on the loam cake 130.The accommodation section 233 of axle 213 from an end that is formed on elongated slot 131 inserted in the elongated slot 131.Axle 213 can be outstanding from loam cake 130, and elongated slot 131 can be formed in the upstream pallet 210.Although the guide portion of present embodiment has the bottom to strengthen its outward appearance and intensity, guide portion can be a through hole.
Middle interconnecting piece 212 (Fig. 7) has following structure: be arranged on engaging with the columnar protrusions 214 along the both sides in the downstream of the discharge direction of recording paper that is arranged on upstream pallet 210 along the semicircle shape axle accommodation section 215 of the both sides of the upstream side of the discharge direction of recording paper of intermediate tray 220.Axle accommodation section 215 has elasticity, and when axle accommodation section 215 held projection 214, opening 215a then turned back to initial position once opening.Projection 214 can be given prominence to from middle pallet 220, and an axle accommodation section 215 can be formed in the upstream pallet 210.
The upstream extremity along the discharge direction of recording paper of intermediate tray 220 (Fig. 7) is connected with upstream pallet 210 rotationally by middle interconnecting piece 212, and the downstream end of intermediate tray 220 is passed through downstream connecting portion 231 and is connected rotationally with downstream pallet 230.
Downstream connecting portion 231 (Fig. 7) has following structure: be arranged on intermediate tray 220 along the semicircle shape axle accommodation section 217 of the both sides in the downstream of the discharge direction of recording paper and engaging from downstream pallet 230 along two of the upstream side of the discharge direction of recording paper side-prominent columnar protrusions 216.Axle accommodation section 217 has elasticity, and when axle accommodation section 217 held projection 216, opening 217a then turned back to initial position once opening.Projection 216 can be given prominence to from middle pallet 220, and an axle accommodation section 217 can be formed in the downstream pallet 230.
By fixed claw 232 downstream pallet 230 is fixed to apparatus main body 110.
In this structure, middle interconnecting piece 212 (Fig. 7) and downstream connecting portion 231 are arranged on the lower face side of discharging pallet 200, pile up recording paper thereby can pile up on the face 200a at recording paper.
The axle accommodation section 215 and 217 of middle interconnecting piece 212 (Fig. 7) and downstream connecting portion 231 is arranged on the two ends of intermediate tray 220, makes opening 215a and 217a point to down.Therefore, when pallet 200 is discharged in assembling, intermediate tray 220 is pushed projection 214 and 216 from the top, and installation shaft accommodation section 215 and 217 easily, therefore can easily carry out assembly operation.
Upstream connecting portion 211 (Figure 12 and Figure 11) comprises elongated slot 131 and axle 213.So, discharge pallet 200 axle 213 since its from focus in the elongated slot 131 along the discharge of recording paper be directed downwards vacillate moving, discharge pallet 200 in middle interconnecting piece 212 and the 231 places bending of downstream connecting portion, discharge pallet 200 and form that whole discharge pallet 200 is recessed be the shape of U-shaped, the misgivings that existence is difficult to pile up recording paper.Therefore, ribs 221 is from the lower surface outstanding (Fig. 1) of middle pallet 220, and the rearward end 110a of these ribs 221 abutment means main bodys 110 is to prevent that discharging pallet 200 forms recessed shape.Replace ribs is set, the upstream extremity 220a of downstream end 210b of upstream pallet (Fig. 7) and intermediate tray can abut against each other, accommodation section, the upstream 230a of the downstream end 220b of intermediate tray and downstream pallet 230 can abut against each other, to avoid this recessed shape.
In said structure, if open loam cake 130 (Figure 11 and Figure 12) around axle 132, then the distance between upstream connecting portion 211 and the downstream connecting portion 231 reduces.So upstream pallet 210 and intermediate tray 220 are followed loam cake 130 and are rotated and bending.Upstream pallet 210 moves along with opening loam cake 130 by the axle 213 of upstream connecting portion 211 with the relative motion between the elongated slot 131 of loam cake 130, and 210 rotations of upstream pallet.At this moment, upstream pallet 210 rotates and moves around middle interconnecting piece 212.Intermediate tray 220 rotates with the identical direction of direction of opening of loam cake 130 around downstream connecting portion 231 edges.Because downstream pallet 230 is fixed to apparatus main body 110, therefore no matter loam cake 130 is opening action or closing motion, downstream pallet 230 does not move.
In said structure, when opening loam cake 130, the position of discharging each element of pallet 200 concerns as follows:
At first, being configured to liken to as the upstream connecting portion 211 of first connecting portion is that the middle interconnecting piece 212 of second connecting portion is low, this upstream connecting portion 211 makes upstream pallet 210 be connected with loam cake 130, and this middle interconnecting piece 212 makes the intermediate tray 220 as another split component be connected with upstream pallet 210.
Preferably, remove the recording paper of discharging on the pallet 200 and open or close afterwards loam cake 130.Yet,, when when the user piles up the state of recording paper on discharge pallet 200 under, opening loam cake 130 mistakenly, can prevent that the recording paper of discharging on the pallet from dropping if set up above-mentioned position relation.
As Figure 11 and shown in Figure 12, when the upstream pallet moves along with opening loam cake 130 and this upstream pallet when rotating, if guarantee the wide space S between escape hole 140 and the upstream pallet 210, can prevent that then recording paper is sandwiched between escape hole 140 and the upstream pallet 210.
Secondly, the bend K that is formed by middle interconnecting piece 212 is configured to be accommodated in the projecting plane when seeing that from ceiling loam cake 130 is positioned at the device of open position.That is to say that this structure prevents that bend K is projected into the outside of the installation region of image processing system.
This can set by the length relation of each member.As selection, as shown in figure 13, can hold intermediate tray 220 by accommodation section, the upstream 230a of downstream pallet 230 and limit rotational action, make bend K be accommodated in the projecting plane.In this case, accommodation section, upstream 230a is a limiting member.
When discharge pallet 200 is closed loam cake 130, image processing system is extended, and folded image form device when opening loam cake.So the occupied area of whole device, erection space do not need very widely when opening loam cake, can save the space.
No matter loam cake 130 is opening action or closing motion, to discharge pallet 200 and do not protrude (giving prominence to) from the installation region of image processing system 100, the occupied area of image processing system, to be that erection space does not need very wide, can save the space.
Be folded into four parts although discharge pallet 200,, similar with Figure 14 and discharge pallet 201 shown in Figure 15, can omit a part that is arranged on the stack portion in the apparatus main body, and discharge pallet 200 and can be folded into three parts.
That is to say, under the situation of Figure 14 and discharge pallet 201 shown in Figure 15, omitted the downstream pallet 230 of discharging pallet 200, by downstream connecting portion 241 with intermediate tray 220 be arranged on rotationally apparatus main body as on the part 250 of discharging pallet.Although the discharge pallet among Figure 14 and Figure 15 is identical with the intermediate tray 220 among Fig. 1 to Figure 13, the discharge pallet among Figure 14 and Figure 15 is represented with Reference numeral 240.
Downstream connecting portion 241 has following structure: be arranged on as the discharge pallet 240 of split component along the semicircle shape axle accommodation section 243 of the both sides in the downstream of the discharge direction of recording paper with engage from two of the part 250 of apparatus main body side-prominent columnar protrusions 242.Axle accommodation section 243 has elasticity, and when axle accommodation section 243 held projection 242, opening 243a then turned back to initial position once opening.Projection 242 can be outstanding from discharging pallet 240, and axle accommodation section 243 can be formed on the part 250 of apparatus main body.
Has the identical effect of image processing system that the image processing system of discharging pallet 201 also demonstrated and had discharge pallet 200.
When opening loam cake 130, as follows as the position relation of each member of the discharge pallet 201 of stack portion:
At first, being configured to liken to as the upstream connecting portion 211 of first connecting portion is that the middle interconnecting piece 212 of second connecting portion is low, this upstream connecting portion 211 makes upstream pallet 210 be connected with loam cake 130, and this middle interconnecting piece 212 makes the discharge pallet 240 as another split component be connected with upstream pallet 210.
Like this, even discharging when opening loam cake 130 mistakenly under the state that piles up recording paper on the pallet 201 as the user, can prevent that also the recording paper of discharging on the pallet from dropping.
Owing to guaranteed the wide space S between escape hole 140 and the upstream pallet 210, therefore can prevent that recording paper is sandwiched between escape hole 140 and the upstream pallet 210.
Secondly, the bend K that is formed by middle interconnecting piece 212 is configured to be accommodated in the projecting plane when seeing that from the top loam cake 130 is positioned at the image processing system of open position.That is to say that this structure prevents that bend K is projected into the outside of the installation region of image processing system.
This can set by the length relation of each member, but as shown in figure 15, can discharge pallet 240 by holding from the outstanding receiving member 251 of the part of apparatus main body, and rotational action is restricted, and bend K can be accommodated in the projecting plane.In this case, receiving member 251 is limiting members.
Like this, no matter loam cake 130 is opening action or closing motion, discharges pallet 201 and do not protrude (giving prominence to) from the installation region of image processing system 100, the occupied area of image processing system, to be that erection space does not need very wide, can save the space.
Discharge the common structure that pallet 200 and 201 has for two and be, is connected with the loam cake 130 with sheet stacking portion 133 as the upstream pallet 210 of split component, this sheet stacking portion 133 is as the split component of the part of formation discharge pallets.In the downstream pallet 230 and 240 as the split component that is connected with apparatus main body 110, the downstream pallet 230 of discharging pallet 200 forms with apparatus main body 110, and the discharge pallet 240 of discharge pallet 201 is connected rotationally with apparatus main body 110.Two upstream extremity and loam cakes 130 of discharging pallet 200 and 201 form, and two downstream end and apparatus main bodies of discharging pallet 200 and 201 are provided with integratedly or are arranged on the apparatus main body rotationally, and are set on loam cake 130 and the apparatus main body.
Although being described in the present embodiment, the sheet stacking device is combined in the image processing system in the apparatus main body integratedly, but, even the sheet stacking device is as being connected with image processing system as the autonomous devices such as collating unit of handling thin slice, the present invention is effective equally.
