PROBLEM TO BE SOLVED: To increase a storage amount of drilling debris by minimizing a decrease in capacity of a drilling debris storage part without newly providing a driving source.SOLUTION: A post-processor includes: a drilling unit 3 for drilling a recording medium P that is carried; a lateral registration detection mechanism 4 for detecting lateral registration displacement of the recording medium; a movement unit 5 for moving the drilling unit in accordance with the lateral registration displacement of the recording medium in which the lateral registration displacement is detected; and a drilling debris collection part 300 for storing drilling debris generated due to a drilling operation of the drilling unit. The drilling debris collection part comprises: a first collection part 302; and a second collection part 303 movable with respect the first collection part, and the second collection part is moved according to a movement of the lateral registration detection mechanism 4 or a movement of the movement unit 5. |
