1. A medium processing device, comprising:
a drum that is rotatably supported, that rotates around a rotation axis, and that winds a medium around a peripheral side surface thereof;
a first tape that, accompanying rotation of the drum, supports the medium while being wound onto and around the peripheral side surface of the drum by sandwiching the medium with the peripheral side surface;
a movable guide configured to movably guide the medium so as to follow an outer diameter of the drum defined by the peripheral side surface and any of the first tape and medium wound thereon, the outer diameter changing as the first tape and medium are wound onto or rewound from the peripheral side surface of the drum;
a pressing roller rotatably attached to the movable guide at a location adjacent to the drum where the first tape is separated from the peripheral side surface of the drum, the pressing roller being biased toward the drum so as to press the first tape toward the drum;
a movable roller rotatably attached to the movable guide at a location away from the drum so as to convey the first tape by rotating the movable roller as the drum rotates; and
a first static electricity elimination section attached at a through hole of the movable guide, between the movable roller and the pressing roller, the first static electricity elimination section being arranged such that a portion thereof projects out through the through hole from the movable guide and abuts the first tape so as to eliminate static electricity from the first tape.
