  In step S <b> 1 shown in FIG. 6, step S <b> 1 is repeated until a staple processing job execution instruction is issued from the control device 138. In step S2, it is determined whether or not the main collection box 139 is attached. If it is determined in step S2 that the main collection box 139 is not attached, the process proceeds to step S3, and a warning indicating that the main collection box 139 is not attached is displayed on the touch panel provided in the copying machine 1. In step S4, it is determined whether or not the current stapling job is “one-sided three-pointing” in which stapling processing is performed at the staple discarding position. If it is determined in step S4 that the stapling job is “three-sided per side”, the process returns to step S1. As a result, unless the main collection box 139 is mounted, the operation related to the staple processing is prohibited. If it is determined in step S4 that the stapling job is not “one-sided three places”, the process proceeds to step S5 to determine whether or not the sub collection box 130b is full, and the sub collection box 130b is full. If it is determined, the process returns to step S1. As a result, unless the main collection box 139 is mounted, the operation related to the staple processing is prohibited. In step S5, if it is determined that the sub collection box 130b is not full, the process proceeds to step S6, an instruction for prohibiting the return to the home position which is also the needle discarding position is issued, and then the process proceeds to step S7. In step S7, it is determined whether or not preparation for the execution of the staple process is completed. If it is determined in step S7 that the preparation is ready, the process proceeds to step S8 to move to the staple processing position and the staple. Execution of stapling at the processing position is instructed, and then the process returns to step S1.

  If it is determined in step S7 that the stapling process is not ready, the process proceeds to step S9 to determine whether or not the stapling job is finished. If it is determined in step S9 that the job has ended, the process waits in step S1 until a processing instruction for the next staple processing job is issued. If it is determined in step S9 that the job has not ended, the process returns to step S7.

  On the other hand, if it is determined in step S2 that the main collection box 139 is attached, the process proceeds to step S10 to instruct to release the prohibition of return to the home position and to move to the home position. In step S11, an instruction to cancel the display indicating that the main collection box 139 is not attached is issued.

  In the staple processing device 13 described above, when “three-sided strike on one side” is selected in which staple processing is performed even when the stapler unit 130 is in the staple discarding position, the stapler unit 130 is in the staple discarding position. If it is detected that the main collection box 139 is not mounted, the staple tip will fall into the apparatus when the staple process is performed, so that “one-sided three-point strike” is selected. While the main collection box 139 is not attached, the stapler unit is prohibited from moving to the staple discarding position, which is an operation related to the staple process, and the staple process. Further, when “square punching” or “one-sided two-point punching” is selected and the main recovery box 139 is not attached, the needle is discarded if the sub-recovery box 130b is not full. Although movement to the home position, which is also a position, is prohibited, stapling is allowed, and when the sub collection box 130b is full, movement to the needle discarding position, which is an operation related to stapling, and execution of stapling are performed. Is prohibited.

  Therefore, according to the staple processing device 13 of the present embodiment, it is possible to prevent the tip of the needle from being discarded at the needle discarding position while the main collection box 139 is not attached.

  Next, an embodiment of a second staple processing apparatus of the present invention will be described.

A recognition unit is provided for recognizing whether or not stapling is performed after moving to the needle discarding position. This point will be described below.

  FIG. 7 is a flowchart of a routine that is started when the power of the staple processing apparatus of this embodiment is turned on.

  In step S21 shown in FIG. 7, step S21 is repeated until an instruction to execute a staple processing job is issued from the control device 138. In step S22, it is determined whether or not the main collection box 139 is attached. If it is determined in step S22 that the main collection box 139 is not attached, the process proceeds to step S23, and a warning indicating that the main collection box 139 is not attached is displayed on the touch panel provided in the copying machine 1. In step S24, it is determined whether or not the current staple processing job is “three-sided strike on one side” in which the staple processing at the staple discarding position is performed. If it is determined in step S24 that the stapling job is “three-sided per side”, the process returns to step S21. As a result, unless the main collection box 139 is mounted, the operation related to the staple processing is prohibited. If it is determined in step S24 that the stapling job is not 'one side three-placed', the process proceeds to step S25. In step S25, it is determined whether or not the sub collection box 130b is full. If it is determined in step S25 that the sub collection box 130b is full, the process returns to step S21. As a result, unless the main collection box 139 is mounted, the operation related to the staple processing is prohibited. If it is determined in step S25 that the sub collection box 130b is not full, the process proceeds to step S26, and it is determined whether or not stapling has been performed after the final return to the home position. If it is determined in step S26 that the stapling process has been performed, the process proceeds to step S27, where an instruction to prohibit returning to the home position, which is also the needle discarding position, is issued, and then the process proceeds to step S28. If it is determined in step S26 that the stapling process has not been performed, the process proceeds to step S33 to instruct movement to the home position, and then proceeds to step S28. In step S28, it is determined whether or not preparation for the execution of the staple process is completed. If it is determined in step S28 that the preparation is ready, the process proceeds to step S29 to move to the staple processing position and Execution of stapling at the stapling position is instructed, and then the process returns to step S1.

  If it is determined in step S28 that the stapling process is not ready, the process advances to step S30 to determine whether or not the stapling job is finished. If it is determined in step S30 that the job is completed, the process waits in step S1 until an instruction to execute the next staple processing job is issued. If it is determined in step S30 that the job has not ended, the process returns to step S28.

  On the other hand, if it is determined in step S22 that the main collection box 139 is attached, the process proceeds to step S31 to instruct to release the prohibition of return to the home position and to move to the home position. In step S32, an instruction to cancel a warning display instruction indicating that the main collection box 139 is not attached is issued.

  In the staple processing apparatus described above, when “one-sided three-point punching” for performing staple processing even when the stapler unit 130 is in the staple discarding position while the main collection box 139 is not mounted is selected. If it is detected that the main collection box 139 is not attached when the stapler unit is at the needle discarding position, the staple tip will fall into the apparatus when staple processing is performed. Is selected and the main collection box 139 is not mounted, the stapler unit is prohibited from moving to the staple discarding position, which is an operation related to the staple process, and the staple process. In addition, when 'square punching' or 'double punching on one side' is selected and the main recovery box is not installed, the needle tip is before the sub recovery box is full. The movement to the needle disposal position and the stapling process are allowed until the presence of the needle is recognized, but it is recognized that the needle tip portion is present before the sub-collection box is full. Although stapling is permitted, movement to the home position, which is also the needle discarding position, is prohibited.

  Therefore, according to the staple processing apparatus of this embodiment, it is possible to prevent the needle tip portion from being discarded at the needle discarding position while the main collection box is not attached. Further, according to the staple processing apparatus of the present embodiment, even when the main collection box is not attached, before the sub collection box is fully detected and until the presence of the needle tip is recognized, the staple disposal position is maintained. Since movement to a certain home position is permitted, staple replenishment is possible while the main collection box is not mounted, which is impossible in the first stapling device embodiment.

  Next, a first embodiment of the third staple processing apparatus of the staple processing apparatus of the present invention will be described.

  The difference between this embodiment and the first and second embodiments of the staple processing apparatus is that in the staple processing apparatus of this embodiment, the engaging member that engages with the engaging portion of the lid of the sub-collection box is staple processing. It is attached to the main collection box, not the frame of the device. That is, in the staple processing apparatus of the present embodiment, if the main recovery box is not attached, the lid is not opened even when the stapler unit reaches the needle discarding position. This prevents the tip of the needle from being discarded.

  FIG. 8 is a diagram illustrating a state in which the engaging member is attached to the main collection box. 8 that are the same as those shown in FIG. 4 are given the same reference numerals as those shown in FIG.

  FIG. 8 shows a state in which an engaging member 1391 that engages with an openable / closable lid 1301b attached to the bottom of the sub collection box 130b is erected on the main collection box 139. FIG. 8 shows a state in which a protrusion for confirming the mounting of the main recovery box 139 is attached to the main recovery box 139. The description of the engagement between the engaging member 1391 and the lid is the same as that described in FIG.

  FIG. 9 is a diagram illustrating a flowchart activated when the staple processing apparatus according to the present embodiment is powered on.

  In step S41 shown in FIG. 9, it is determined whether or not a staple processing job is instructed, and step S41 is repeated until a staple processing job is instructed. In step S42, the movement of the stapler unit to the home position, which is also the needle discarding position, is instructed. In step S43, it is determined whether or not the main recovery box is mounted. In step S43, the main recovery box is mounted. If it is determined, the process proceeds to step S44, and it is determined whether or not the needle tip is full.

If it is determined in step S56 that the staple process is ready, the process advances to step S57 to instruct the movement to the staple process position and the execution of the staple process.

  If it is determined in step S53 that the main recovery box is attached, the process proceeds to step S58, and the plunger 1304b shown in FIG. 10 is instructed to open the lid 1301b. Thereafter, the process proceeds to step S55. If it is determined in step S55 that the needle tip is full, the process returns to step S53. If it is determined in step S56 that the stapling process is not ready, the process advances to step S59 to determine whether or not the stapling job has been completed. If it is determined in step S59 that the job has not ended, step S59 is performed. Returning to S56, if it is determined in step S59 that the job has ended, the process returns to step S51.

  In the staple processing apparatus of the present embodiment described above, the disposal of the needle tip portion depends on whether or not the plunger unit 1304b is instructed to open the lid, so that the main collection box detects that it is not attached. While the cover is not instructed to open, the stapler unit is allowed to move to the staple discarding position and staple processing until it is detected that the sub collection box is full.

  Therefore, the staple processing device of this embodiment can also prevent the tip of the needle from being discarded at the needle discarding position while the main collection box is not attached.
