Figure 10 is the block diagram of configuration that the control part of sheet treatment facility 400 is shown.Reference number 100 is represented CPU, and wherein, CPU is in an embodiment as the example of control setup.CPU 100 has ROM 110.Be stored among the ROM110 with the corresponding program of control program shown in Figure 11 and 12 etc.CPU 100 controls each part the fetch program.
In CPU 100, comprise RAM 121.Action data and input data are stored among the RAM121.CPU 100 controls based on described program when inquiry is stored in data among the RAM 121.The input port of CPU 100 is connected to such as inlet sensor 403 and the stacked sensor that draws off sensor 415 of sheet.The output port of CPU 100 is connected to motor sum spiral pipe, stackedly draws off motor 430 as transmitting motor 431, biasing motor 432, sheet, picks up screw actuator 433 and clamp solenoid 434.CPU 100 controls the load of each motor sum spiral pipe according to the sensor-based state of described program, and wherein, described motor sum spiral pipe is connected to output port.
Because image forming apparatus main body 500 is grasped the size that draws off the thin slice S that part 208 draws off from thin slice, therefore, the control part of control part (CPU100) and image forming apparatus main body 500 that comprises the sheet treatment facility 400 of microcomputer system carries out serial communication, and this allows to grasp the size that is inserted into the thin slice S on the process disk 410.
Correspondingly, at every turn when the image forming apparatus main body draws off (transmission) thin slice S, the control part of sheet treatment facility 400 (CPU 100) is grasped the size of thin slice S, and CPU100 controls the amount of exercise of biasing cylinder 407 on Width by control biasing motor 432.Thereby biasing cylinder 407 can move corresponding amount according to the size that is inserted into the thin slice S on the process disk 410, and the side part of thin slice S nestles up location wall 416 reliably.
In an embodiment, be layered in the part of the stacked SA formation of the sheet process disk 410 on the stacked dish 421 of sheet.Thereby, when when process disk 410 draws off the stacked SA of sheet, reduce the stacked dish 421 of sheet, till the upper space that is layered in the stacked SA of sheet on the stacked dish 421 of sheet is corresponding with process disk 410 substantially by the stacked dish rising/decline of sheet motor (referring to Figure 10).
Below, the thin slice of the embodiment that as above disposes in conjunction with flow chart description shown in Figure 11 and 12 is handled operation.
When image forming apparatus main body 500 beginning images formed operation, the CPU 100 (referring to Figure 10) of sheet treatment facility 400 checked that whether receiving thin slice from image forming apparatus main body 500 draws off signal (S100).When the reception thin slice draws off signal ("Yes" among the S100), open and pick up screw actuator 433 (S110), the biasing cylinder 407 that pull-up is supported by biasing roller arms 406.
Then, open to transmit motor 431 (S120), thereby, be installed in the conveying roller 405 that thin slice unloads in the middle of the outbound path and can on the direction similar, transmit thin slice S to the thin slice unloading direction of image forming apparatus main body 500.When the front end process of initial thin slice S enters the mouth sensor 403, open inlet sensor 403 ("Yes" among the S130).Then, thin slice S arrives conveying roller 405, and this allows from conveying roller 405 transferring power.When thin slice S draws off part 208 (referring to Fig. 1) when separating ("Yes" among the S140) with thin slice in the image forming apparatus main body 500, finish the transmission of thin slice S.
When conveying roller 405 is sent to process disk 410 to thin slice S, pick up screw actuator 433 (S150) through closing before the conveying roller 405 fully at thin slice S.Then, make biasing cylinder 407 rely on deadweight and drop on the thin slice S.As shown in Figure 6A, biasing cylinder 407 is sent to desired location (S160) to thin slice S.When thin slice S is sent to the desired location ("Yes" among the S160), stop to transmit the rotation (S170) of motor 431, and, stop the transmission of thin slice S.
When biasing cylinder 407 stops the rotation, open clamp solenoid 434 (S180), and, be installed near the thin slice clamping part 412 on the original position of thin slice rear end limiting stopper 411 and shown in Fig. 6 B, open.Then, transmit motor 431, to utilize bias roller tube 407 thin slice S is pulled back (S190), and the rear end of thin slice S nestles up thin slice rear end limiting stopper 411 to rotate in the opposite direction with the sender.
In the rear end that makes thin slice S during near thin slice rear end limiting stopper 411, consider crooked at the thin slice S that when image forming apparatus main body 500 transmits thin slice S, produces, set the rotation amount of biasing cylinder 407, thereby thin slice S can transmit longlyer a little than stop to transmit the spacing distance of determining between 411 of point and thin slice rear end that turns to execution at thin slice S.
Based on the dimension information of image forming apparatus main body 500 and check the size (S200) of unloading slice S, and, calculate and unload the side-play amount of the consistent size of slice S.That is to say, calculate as thin slice S momental offset movement amount (S210) on Width.Thin slice S is that to be pressed onto location wall 416 necessary being discharged to thin slice S on the process disk 410 at the amount of exercise on the Width.
Drive biasing motor 432, with the offset movement (S220) of the cylinder 407 that begins to setover.When moving biasing cylinder 407, rely on the friction force of biasing cylinder 407, the thin slice S that on the direction of location wall 416, moves biasing cylinder 407 and contact with biasing cylinder 407.At this moment, shown in Fig. 8 B, thin slice clamping part 412 rotates up, thereby thin slice clamping part 412 does not become the burden that hinders thin slice S motion.
Shown in Fig. 6 C, by the offset movement operation of biasing cylinder 407, thin slice S nestles up location wall 416, and this carries out the alignment of thin slice S on Width.Make after thin slice S nestles up location wall 416 at biasing cylinder 407, biasing cylinder 407 is mobile a little when sliding on thin slice S, and cylinder 407 stops to setover.In order to be corrected in the offset movement offset in alignment on direction of transfer afterwards, carry out biasing cylinder 407 and reverse once more with the alignment operation (S230) that retracts thin slice S, and, finish the alignment of the first thin slice S.
When finishing the alignment of the first thin slice S, shown in Fig. 7 A, open and pick up screw actuator 433 (S240), with rise biasing cylinder 407, and, close clamp solenoid 434 (S250).Thereby, shown in Fig. 7 B, thin slice clamping part 412 closures, the thin slice S that has been performed alignment is clamped and is fixed.As a result, can prevent that the thin slice S that draws off subsequently from introducing first and unloading slice.
Then, shown in Fig. 7 B, by biasing motor 432 and by being in the rack-and-pinion of rise state, biasing cylinder 407 returns and moves to original position (S260).
The original paper last page corresponding last (S270) whether the thin slice S on the process disk 410 is and will be copied is left in inspection in.When determining that based on the information that sends from image forming apparatus main body 500 thin slice S is not last thin slice S ("No" the S270), flow process turns back to S100, and, receive the thin slice that sends from image forming apparatus main body 500 and draw off signal.Repeat flow process, till in process disk 410, depositing last thin slice S.
In embodiment configuration, when image forming apparatus main body 500 was unloaded slice S, the control part of sheet treatment facility 400 (CPU 100) calculated the offset movement amount that is suitable for thin slice S when grasping thin slice S size at every turn.Correspondingly,, the thin slice S that contacts with biasing cylinder 407 is carried out registration process based on the amount of exercise that calculates, and, with location wall 416 alignment thin slice S.
When definite thin slice S is last thin slice S ("Yes" among the S270),, therefore checks and whether select binding to handle (S280) owing on process disk 410, form with the corresponding sheet of the original paper that is copied is stacked.When selecting binding to handle ("Yes" among the S280), drive stapler unit 420, on binding position shown in Figure 13, carry out binding and handle (S290).

When not selecting bookbinding to handle ("No" among the S280), perhaps after finishing the bookbinding processing, under the state that the stacked SA of sheet is fixed by thin slice clamping part 412, the stacked motor 430 that draws off of sheet makes the stacked parts 413 that draw off of sheet advance towards the direction of the stacked dish 421 of sheet, and, draw off the stacked SA of sheet (S300).
Draw off operation and synchronously carry out the motion of the stacked dish 421 of sheet (decline) and handle (S310) with sheet is stacked, and the stacked parts 413 that draw off of sheet turn back to original position (S320).In order to stop the rotation of conveying roller 405 and biasing cylinder 407, stop to transmit motor 431 (S330), and close and pick up screw actuator 433 (S340), this descends biasing cylinder 407, to finish the processing of described series.
As mentioned above, when thin slice S was sent to the stacked dish 421 of sheet, biasing cylinder 407 made thin slice S near location wall 416, so that it is in the end part aligning of the mutually different thin slice S of the length on the Width on Width.Thereby, even the stacked SA of sheet comprises the mutually different thin slice S of size, also carry out bookbinding reliably and handle, and when the stacked SA execution of sheet bookbinding was handled, it is better that the outward appearance of the stacked SA of sheet becomes.Move thin slice S so that near the location during wall 416, in broad ways because therefore the thin slice S of thin slice clamping part 412 fixing previous alignment, will never produce the mixed and disorderly of alignment.
