After the paper P on the standby tray 10 is dropped and supplied to the processing tray 12, the paper P is subjected to processing such as stapling in the processing tray 12.

  FIG. 4 is a side view of the processing tray 12 as viewed from the conveying belt 47b side. The conveyor belt 47 b has a feed claw 51 b and the drive roller 48 is connected to the motor 52. The conveyor belt 47 a provided to face the conveyor belt 47 b has a feed claw 51 a, and the driving roller 48 is connected to the motor 52. By driving the motor 52, the driving roller 48 rotates, and the driving speed of the motor 52 can be adjusted.

  The conveyor belts 47 a and 47 b are endless belts that are stretched around the driving roller 48 and the driven roller 49. The driven roller 49 and the conveying belts 47a and 47b rotate by the rotation of the driving roller 48 by the driving of the motor 52. The transport belt 47a has a feed claw 51a, and the transport belt 47b has a feed claw 51b. The feed claws 51a and 51b rotate as the conveyor belts 47a and 47b rotate. The sheet bundle T is conveyed by being hooked on both sides of the sheet bundle T by the feeding claw 51a of the conveying belt 47a and the feeding claw 51b of the conveying belt 47b, and hooked by the feeding claw 50a of the conveying belt 50 on the rear end of the sheet bundle T.

The CPU 501 controls driving of the motor 505 based on the input signal.

  For example, a signal from a sensor 81 that detects the stacking limit of the paper P is input to the CPU 501.

  For the control of the sheet processing device 7, the abnormality detection control, and the display control for the display unit 507, the CPU 501 executes a program written in the storage unit 506. Further, the display control of the operation display unit in the image forming apparatus 5 is controlled by the CPU of the image forming apparatus 5 in accordance with the control output from the CPU 501.

  Next, a series of flows of the paper P in the paper processing apparatus 7 will be described. There are three transport paths for the paper P. The first route is a route through which the paper P is discharged to the fixed tray 70 without performing any processing. The second route is a route in which the sheet P is discharged to the first discharge tray 16 or the second discharge tray 18 without being processed. The third route is a route on which processing is performed and the sheet P is discharged from the first discharge tray 16 or the second discharge tray 18.

  First, the first route will be described with reference to FIG. When the sheet P is not processed and is discharged to the fixed tray 70, the sheet P discharged from the sheet feed roller 6 of the image forming apparatus 5 is discharged from the sheet discharge rollers 76 and 77 through the tray path 74 by the entrance roller 22. To the fixed tray 70. At this time, the fixed tray 70 is disposed so as to be inclined so that the front end side of the paper P is higher than the rear end side. As a result, the sheet P returns to the arrow x direction, which is the sheet rear end direction, by using the inclination of the fixed tray 70, and the rear end abuts against the tray rib 80 and is vertically aligned. Similarly, the sheets P discharged from the image forming apparatus 5 are sequentially discharged to the fixed tray 70 until they reach a predetermined number and are vertically aligned.

  Next, the second route will be described. When the processing is not performed and paper is discharged to the first paper discharge tray 16 or the second paper discharge tray 18, for example, the first paper discharge tray 16 is at a position indicated by a dotted line in FIG. It is sliding. As a result, the first paper discharge tray 16 can stack the paper P discharged from the standby tray 10 with good consistency. When not processed, the paper P transported to the entrance roller 24 is fed to the standby tray 10 by the paper feed roller 24 and transported to the paper feed roller 24 through the paper path ceiling 36. Is done. Next, the paper P is transported by the standby tray roller 28 that is lowered onto the standby tray 10 and rotated in the direction of the arrow f, and is discharged onto the first paper discharge tray 16. The paper P may be discharged not to the first paper discharge tray 16 but to the second paper discharge tray 18.

  Next, the third route will be described. When performing the stapling process, in the standby tray 10, in FIG. 2, the tray members 10a and 10b can slide and move in the direction opposite to the arrow m direction or the arrow n direction, respectively, to support the paper P. Yes. In FIG. 1, the standby tray roller 28 is retracted above the standby tray 10 so as not to interfere with the paper P. The paper P supplied by the paper feed roller 24 discharged from the image forming apparatus 5 is placed on the standby tray 10 in order to wait for the processing tray 12 to become empty.

  When the preceding paper P on the processing tray 12 is discharged to the first paper discharge tray 16 side and the processing tray 12 is emptied, the standby tray 10 has the tray members 10a and 10b in FIG. Slide and move in the direction of arrow n. Further, the conveyance belts 47a and 47b are arranged so that the width between the conveyance belts 47a and 47b is substantially the same as that of the paper P in order to align the lateral direction of the paper P dropped from the paper feed roller 24. As a result, the paper P fed by the paper feed roller 24 is directly dropped onto the processing tray 12 without being interrupted by the standby tray 10.

  At the time of drop supply, the upper vertical alignment roller 38a is retracted upward, and the receiving portion of the paddle 44 receives the rear end of the paper P. The sheet P falls while contacting the conveyor belts 47a and 47b, and both sides of the sheet are aligned. Next, the paddle 44 is rotated to drop the rear end of the paper P from the receiving portion 44a, and is dropped onto the processing tray 12 by the hitting portion. Further, the paddle 44 feeds the paper P by the feeding unit, and the rear end of the paper P is brought into contact with the stopper 45 to complete the vertical alignment of the paper P. The vertical alignment of the paper P on the processing tray 12 may be performed by the upper vertical alignment roller 38a by moving the upper vertical alignment roller 38a up and down each time. In this way, the image-formed sheets P are stacked directly on the processing tray 12 from the sheet feed roller 24 while sequentially aligning in the horizontal and vertical directions.

  FIG. 6 is a flowchart showing conveyance from the processing in the processing tray 12 to the first paper discharge tray 16. The paper P on which an image is formed by the image forming apparatus 5 is conveyed to the paper processing apparatus 7. In 600, it is determined whether or not the number of sheets P loaded on the processing tray 12 by the sheet P conveyed from the image forming apparatus 5 has reached a predetermined number. If the number of sheets P has not reached the predetermined number (No in 600), the determination is repeated until the predetermined number is reached. If the number of sheets P stacked on the processing tray 12 has reached the predetermined number (Yes in 600), it is determined in 601 whether or not stapling has been completed. The stacked paper P forms a paper bundle T by stapling. If the stapling process has not been completed (No in 601), the determination is repeated until the stapling process is completed.

The feed claws 50a, 51a, 51b return to HP after making one rotation by driving each motor.

  Subsequently, at 604, it is determined whether or not the feed claws 50a, 51a, 51b have returned to HP. If the feed claws 50a, 51a, 51b have not returned to HP (No in 604), the determination is repeated until the feed claws 50a, 51a, 51b return to HP. When the feed claws 50a, 51a, 51b return to the HP (Yes in 604), in 605, the driving of the motor 52 that rotates the conveyor belts 47a, 47b and the motor that rotates the conveyor belt 50 is stopped, and the process ends. .
