  First, in step S10, a job is accepted by operating the operation unit 94 from a standby state.

  Next, in step S12, when the storage detector 82 detects that the storage box 70 of the storage unit 45a and the storage box 70 of the storage unit 45b are present in the post-processing device main body 15 (detection of the storage units 45a and 45b). (FIG. 12 (a)), the shutter 74 is closed and fixed at a position where the handle 72 is shielded (locking portions 45a and 45b) (FIG. 12 (b)).

  Next, in step S14, the fullness detection unit 80 determines whether or not the unnecessary portion CP accommodated in each accommodation box 70 of the accommodation units 45a and 45b is full, and both the accommodation boxes 70 of the accommodation units 45a and 45b. Is full (accommodating portions 45a and 45b full detection ON), the discharge is disabled and the full detection of the accommodating portions 45a and 45b is notified, and the apparatus is stopped (step S16, FIG. 12 (l)). .

  Next, in step S18, if it is determined in step S14 that the storage box 70 is not full (full detection OFF), the discharge destination is switched to a full detection OFF storage unit. Here, it demonstrates as switching to the accommodating part 45a first.

Next, in step S20, the shutter 74 of the housing portion 45a designated as the discharge destination is fixed in a position where the handle 72 is shielded while being closed (the housing portion 45a is locked), and the housing portion 45b not designated as the discharge destination. The shutter 74 is opened and moved to a position where the handle 72 is opened (unlocking the accommodating portion 45b) (FIG. 12C).
That is, with respect to the storage unit 45 that is designated as a discharge destination and is being discharged, the removal is locked, and the storage unit that is not discharged is unlocked.

  Next, in step S22, the discharge of the unnecessary portion CP of the recording medium cut in the cutting portion 46 to the accommodating portion 45a is started (FIG. 12D).

  Next, in step S24, when the fullness detection unit 80 detects that the storage box 70 of the storage unit 45a is full (storage unit 45a full detection ON), the fullness detection unit 80 performs full detection of the storage unit 45a. Notification is made (FIG. 12E).

  Next, in step S30, if it is determined in step S26 that the storage box 70 of the storage unit 45b is not full (the storage unit 45b full detection OFF), the shutter 74 of the storage unit 45b is closed and fixed at a position where the handle 72 is shielded. The storage unit 45b is locked (FIG. 12 (f)), and the switching unit 53 switches the discharge destination of the unnecessary part (CP) to the storage unit 45b (step S32, FIG. 12 (g)), without stopping the apparatus. Continue to discharge.

  Next, in step S34, the shutter 74 of the accommodating portion 45a is opened and moved to a position where the handle 72 is opened (unlocking the accommodating portion 45a) (FIG. 12 (h)), and the accommodating box 70 of the accommodating portion 45a can be taken out. It becomes a state.

  Next, in step S36, the storage detector 82 determines whether or not the storage box 70 of the storage unit 45a has been removed from the post-processing apparatus main body 15. When the storage box 70 is removed, the storage box 70 is removed. It is determined that the container 45a is detected (step S38, FIG. 12 (i)). Then, the accommodation detection unit 82 detects the installation of the accommodation box 70 of the accommodation unit 45a (accommodation unit 45a detection ON) (step S40, FIG. 12 (j)).

  Next, in step S42, the fullness detection unit 80 determines whether the storage box 70 of the storage unit 45a is full.

  In step S42, when it is detected that the storage box 70 of the storage section 45a is full (storage section 45a full detection ON), the process returns to step S36, and it is detected that the storage box 70 of the storage section 45a is not full (storage section 45a). When full detection is turned OFF, full detection of the storage unit 45a is canceled (step S44), and the process returns to step S24.

  In step S36, if it is determined by the storage detection unit 82 that the storage unit 45a has not been taken out (storage unit 45a detection ON), the discharge to the storage unit 45b is continued (step S46).

  When discharging to the storage unit 45b is continued and the fullness detection unit 80 detects that the storage unit 45b is full (storage unit 45b full detection ON) (step S48, FIG. 12 (k)), the storage units 45a and 45b. Is detected and the apparatus is stopped (step S50, FIG. 12 (l)).
