If the trailing edge of the sheet S is detected by the sheet detector 90 from the time when the second predetermined time elapses, it is determined that the sheet S has been normally conveyed, and thereafter the operation of the entire apparatus is continued in the same manner. However, when the front end of the paper S cannot be detected by the paper detector 90 before the first predetermined time elapses, or the rear end of the paper S cannot be detected by the paper detector 90 before the second predetermined time elapses. Then, it is determined that the conveyance failure of the sheet S has occurred on the upstream side or the downstream side of the sheet detector 90, and the operation of the entire apparatus is stopped.

[Operation]
The operation of the sheet processing apparatus of this embodiment will be described. 5 and 6 are schematic explanatory views of the main part of the sheet processing apparatus as viewed from above.

  First, the processing conditions of the paper S are set by the input unit 7 so that the paper S is cut as shown in FIG. This setting is normally performed by the operator operating the operation panel 70. However, the barcode indicating the processing conditions printed on the paper S is automatically displayed by the CCD sensor 31 together with the registration mark. It may be performed by reading, or may be performed by a personal computer or other terminal device connected to the outside of the apparatus main body 10.

  Next, under the control of the control unit 6, the cutting blade moving means 81 is operated to rotate each screw shaft 401 while detecting the amount of rotation of the screw shaft 401, and 880 follows each guide shaft 402. Move in the paper width direction. Thereafter, when the cutting blade 801 is positioned at the cutting position, the operation of the cutting blade moving means 81 is stopped, and the rotation of the screw shaft 401 is stopped. In FIG. 5, the cutting position is set near the center in the paper width direction.

  Further, when the exclusion member moving means 51 is operated under the control of the control unit 6, the screw shaft 510 is rotated while the rotation amount of the screw shaft 510 is detected, and the exclusion member 50 is moved along each guide shaft 511. Move in the paper width direction. Thereafter, when the guide portion 506 is located at a position where it contacts the cutting waste SW, the operation of the exclusion member moving means 51 is stopped, and the rotation of the screw shaft 510 is stopped. In FIG. 5, the cutting waste SW is set to be generated on the right side of the cutting position.

  Further, when the detector moving means 91 is operated under the control of the control unit 6, the screw shaft 910 is rotated while the rotation amount of the screw shaft 910 is detected, and the sheet detector 90 is moved to each guide shaft 911. Along the paper width direction. After that, when the paper detector 90 is located within the widthwise conveyance range of the paper S that is continuously conveyed on the paper conveyance path 21 after the cutting waste SW is removed, the operation of the detector moving unit 91 is stopped. Thus, the rotation of the screw shaft 910 stops. In FIG. 5, the cutting waste SW is eliminated, and the sheet S that is continuously conveyed and remains on the sheet conveying path 21 is set to be generated on the left side of the cutting position.

  Then, the respective driving means (not shown) connected to the sheet feeding table 111, the suction conveying belt 112, and the conveying roller 20 are operated to send out the sheets S stacked on the sheet feeding table 111 one by one from the top to the downstream side, The front edge of the fed paper S is detected by the paper front edge sensor 30, and then a barcode or a registration mark is appropriately read from the paper S conveyed immediately below the CCD sensor 31 by the CCD sensor 31 and conveyed to the paper processing unit 4. To do.

  Further, when the driving means (not shown) connected to the drive shaft 403 is operated, the rotary blade 801 is rotated. The paper S that has reached the paper processing unit 4 is cut along the paper transport direction X1 by the rotating cutting blade 801, and is further transported downstream.

  Of the sheets S cut by the cutting blade 801, the right sheet contacts the guide portion 506 of the exclusion member 50. The guide unit 506 deflects the conveyed paper S, that is, the cutting waste SW in a downward direction, and collects the cutting waste SW in the trash box 13. Further, among the sheets S cut by the cutting blade 801, the left side sheet S does not contact the guide portion 506 of the exclusion member 50, so that it remains on the sheet conveyance path 21 and is continuously conveyed, and the sheet detector 90 is The sheet S that is continuously conveyed is detected.

The paper S that has passed through the paper detection unit 9 is further transported and discharged onto the paper discharge tray 12. In the case of processing a plurality of sheets S, the sheet S is sent out from the sheet feed table 111 by the suction conveyance belt 112, conveyed by the conveyance roller 20, cutting by the sheet processing unit 4, and cutting waste removing means 5 Repeat the elimination of the cutting waste SW.

  Also, under the control of the control unit 6, the front end of the paper S is detected by the paper detector 90 until the first predetermined time elapses from the time when the front edge of the paper S is detected by the paper front edge sensor 30, and the paper detection When the trailing edge of the sheet S is detected by the sheet detector 90 from when the leading edge of the sheet S is detected by the container 90 until the second predetermined time has elapsed, it is determined that the sheet S has been normally conveyed. In the same manner, the operation of the entire apparatus is continued. However, when the front end of the paper S cannot be detected by the paper detector 90 before the first predetermined time elapses, or by the paper detector 90 until the second predetermined time elapses. If the trailing edge of the sheet S cannot be detected, it is determined that a conveyance failure of the sheet S has occurred on the upstream side or downstream side of the sheet detector 90, and the operation of the entire apparatus is stopped.

  After processing a predetermined number of sheets S, the operation of the entire apparatus is stopped.

  Further, when the processing conditions of the paper S are changed so as to perform the cutting processing of the paper S as shown in FIG. 6, that is, the processing conditions after the setting change are shown in FIG. It is the same as the cutting position, and the cutting waste SW is generated on the left side of the cutting position. The cutting waste SW is eliminated, and the paper S that is continuously conveyed on the paper transport path 21 is on the right side of the cutting position. The operation of the paper processing apparatus when the setting is changed to the setting that occurs in the operation of the cutting blade moving means 81, the exclusion member moving means 51, the detector moving means 91, and the removal of the cutting waste SW and the paper detector. Only the detection of the sheet S by 90 will be described, and the other operations are the same as before the setting change, and thus description thereof will be omitted.
