Post-processing device

A post-processing device comprising:

• a mounting section on which a medium before being subjected to post-processing by a post-processing section is to be mounted;
• an aligning section that aligns ends of a plurality of media stacked on the mounting section;
• a transport section that transports the medium on the mounting section toward the aligning section in a transport direction;
• a feeding section that is provided between the transport section and the aligning section and feeds the medium in the transport direction by rotating about a rotational shaft;
• a controller configured to control the rotational shaft;
• and
• a pressing section that is provided between the transport section and the aligning section and, by rotating about the rotational shaft in a rotational direction identical to a rotational direction of the feeding section, applies, to the medium, a pressing force having a component in a direction opposite from the transport direction, wherein
• the pressing section is provided at a position preceding the feeding section in the rotational direction, and
• wherein the controller controls the rotational shaft to cause the pressing section to apply the pressing force to a top planar surface of the medium.

• a transport section that transports the medium on the mounting section toward the aligning section in a transport direction;
• a feeding section that is provided between the transport section and the aligning section and feeds the medium in the transport direction;
• a pressing section that is provided between the transport section and the aligning section, applies, to the medium, a pressing force having a component in a direction opposite from the transport direction, and applies the pressing force to the medium before the feeding section applies a feeding force to the medium;
• and
• a controller configured to control the pressing section,
• wherein the controller controls the pressing section to cause the pressing section to apply the pressing force to the medium after an end of the medium reaches the aligning section.
