[modification of second embodiment]
When a large amount of plain papers (for example, 1500 plain papers) are loaded to removable pallet 140, because the caused noise of vibration of paper rear end becomes very remarkable.Therefore, when the cargo-carring paper amount of institute was very little on removable pallet 140, paper end support component 190 can not operated.Now, with illustrating that a large amount of in this embodiment paper are loaded in the situation on the removable pallet 140, wherein, discharge control and drive paper end support component 190 with mobile linkage manner with removable pallet 140.
Figure 13 is used to illustrate that paper discharges the diagram of circuit of an example of control.When starting image formation processing by the instruction from guidance panel 5 or PC 320, in 1210, removable pallet 140 moves to the holding fix that detection part 132 detects the upper surface of removable pallet 140.Image processing system 1 forms image on paper.In 1220, when waiting for that roller 112 or paper bundles output block 120 are discharged paper, removable pallet 140 receives the paper of being discharged.End portion supports parts 190 are waited for, do not drive with moving synchronously of removable pallet 140.
In 1230, controller 310 obtain in removable pallet 140 the height H of cargo-carring paper.In this embodiment, removable pallet 140 detects the position reception paper subsequently of removable pallet 140 upper surfaces at detection part 132.Therefore, controller 310 obtains the height H of paper according to the pulse count of the position of the removable pallet 140 that is detected by detection part 134 or driving motor M2.In addition, also can be provided for detecting the sensor of paper height.
In 1240, whether controller 310 decision height H are greater than reference value I.The value (threshold value) of reference value I for setting as predetermined altitude.Initial value should find become height under the significant situation of noise in the generation that vibration causes of paper rear end just by theoretical formula or test results.In addition, can set initial value according to paper type.Also can come initial value definition by maker.Perhaps, initial value can be defined by the setting that utilizes guidance panel 5 or PC 320 by the handler of user or appointment., first value will be called herein, and second value will be called greater than the value of reference value I less than the value of reference value I.
(1240: not), end portion supports parts 190 are waited for, synchronously do not drive with moving of removable pallet 140 during less than reference value I when height H.When height H equals reference value I or during greater than second value of reference value I (1240: be), in 1250, the synchronously operation of moving of end portion supports parts 190 and removable pallet 140.
This embodiment has produced and the first embodiment similar effects, can reduce the load to the drive configuration 142 of removable pallet 140.In addition, according on removable pallet 140 the height of cargo-carring paper support component 190 is changed into serviceability from wait state so that removable pallet 140 moves, thereby suppress watt loss.Herein, in this embodiment, although value H and reference value I are the value relevant with removable pallet 140, they also can be other values relevant with the paper number that is sent to removable pallet 140.In this case, master controller 300 or controller 310 judge paper numerical value H ' whether greater than reference value I '.Reference value I ' for being set at the value (threshold value) of predetermined paper number.According to the instruction that is received from guidance panel 5 or PC 320, master controller 300 can be set the paper numerical value H ' of the paper that is sent to removable pallet 140.Perhaps, can come to come the paper number is counted by the paper transport path that is provided for detecting the paper that forms image thereon by master controller 300 or controller 310.
Now, the operation when discharging with reference to Figure 12 A and Figure 12 B explanation.When discharging paper by processing pallet 114, shown in Figure 12 A, gate 160 is waited at the first holding fix place, can not hinder the discharge (open mode) of paper.The paper that is discharged to removable pallet 140 is owing to the inclination of the loading surface of removable pallet 140 moves to gate 160 sides.Subsequently, the rear end of paper contacts with gate 160.
For example, when a piece of paper or plurality of sheets of paper were discharged to removable pallet 140, removable pallet 140 descended.When detection part 132 finishes the detection above the table of on the removable pallet 140 cargo-carring paper of institute, removable pallet 140 risings.Subsequently, removable pallet 140 move to detection part 132 detect on removable pallet 140 the position of upper space of cargo-carring paper, and load the paper of being discharged.According to this embodiment, to discharge, discharge or cargo-carring paper amount in response to paper from the paper of handling pallet 114 from waiting tray 110, removable pallet 140 reduces gradually.
Shown in Figure 12 B, to such an extent as to when discharging too many removable pallet 140 declines of paper above the desired location, the belt conveyor 196 of paper end support component 190 begins to support one by one the end of paper from the paper of removable pallet 140 bottoms.According to this embodiment, as mentioned above, the surface of belt conveyor 196 is positioned at removable pallet 140 sides, rather than the outside face of cover 136.Therefore, prevent as much as possible or reduced contacting of paper end and cover 136.
The sheet post-process apparatus 100 of this embodiment is provided with paper end support component 190, and it has the belt conveyor 196 that is used for the identical distance of the miles of relative movement that moves with operation of removable pallet 140 linkage manner and removable pallet 140.Therefore, removable pallet 140 can move up and down, and the rear end of paper is not contacted with paper end support component 190 with cover 136.Therefore, can be suppressed on the removable pallet 140 the caused noise of vibration of rear end of cargo-carring a large amount of paper.
In this embodiment, paper end support component 190 is configured to make gate 160 and belt conveyor 196 to overlap each other on the moving direction of removable pallet 140.But paper end support component 190 can be configured in the more position of below, makes gate 160 and belt conveyor 196 not overlap each other.When a large amount of plain papers (for example, 1500 common paper) are loaded into removable pallet 140, become remarkable by the caused noise of the vibration of paper rear end.Subsequently, paper end support component 190 can be configured in the remarkable position place because the caused noise of vibration becomes.
As shown in figure 14, reservations (for example, across the surface of pulley 192 belt conveyor 196 relative with 194 in removable pallet 140 sides) become the position that the outside face than the cover 136 of sheet post-process apparatus 100 more approaches removable pallet 140 sides.Therefore, on removable pallet 140 the rear end of cargo-carring paper contact with the belt conveyor 196 that is positioned at this scope H.In addition, accessory 198 is configured in the rear side of belt conveyor 196.Accessory 198 is adjusted in moving of belt conveyor 196 on the thickness direction of the belt conveyor 196 that the rotation direction with belt conveyor 196 intersects in scope H.For example, when with a large amount of paper loadings on removable pallet 140 time, because the paper own wt, and on the surface of the belt conveyor 196 that contacts with paper, vertically applied power.Accessory 198 define by on removable pallet 140 the moving of the caused belt conveyor 196 on first direction of cargo-carring paper.That is, accessory 198 keeps this state, and the surface that promptly is used to load the belt conveyor 196 of paper becomes and has the position of more approaching removable pallet 140 sides than the outside face of cover 136.In addition, in Figure 14, the surface of cover 136 is positioned at long and short dash line D place.
The present invention is not restricted to above-mentioned embodiment, but under the situation of its claim scope, can carry out various modifications.
