Medium transport apparatus, medium feeder, and image formation system

An image formation system comprising:

• a medium feeder;
• and
• an image formation apparatus, wherein
• the medium feeder comprises:
• a medium separator comprising:
• a stacker that holds media as stacked one on another;
• and
• a separation part that separates a medium from the media on a one-by-one basis;
• and
• a medium transport apparatus that transports the medium separated from the media by the medium separator,
• the medium transport apparatus comprises:
• a frame;
• a table comprising a placement surface on which the medium is placed, a first end portion and a second end portion, the table extending from the first end portion to the second end portion and being rotatable about a first shaft portion parallel to the placement surface;
• a first rotor arranged adjacent to the first end portion of the table;
• a second rotor arranged adjacent to the second end portion of the table;
• a belt that is stretched by the first rotor and the second rotor, and is configured to rotate circularly and to transport the medium in a first direction from the first end portion toward the second end portion;
• a biasing part that links the frame and an attachment part located between the second end portion and the first end portion in the table and which biases the table upward;
• and
• a first guide portion and a second guide portion provided on the table at positions different from each other both in the first direction and in a second direction orthogonal to the first direction,
• the image formation apparatus comprises an attached part to which the medium transport apparatus is detachably attachable, and
• the attached part comprises a guide surface in contact with at least one of the first guide portion and the second guide portion.
