Transport device

A transport device comprising:

• a first roller that transports paper-sheets in a predetermined transport direction by rotation thereof;
• a second roller that rotates with rotation of the first roller, and regardless of from which direction the paper-sheets hit a contact point with the first roller, moves in a direction diagonally forward than a vertical direction with respect to the transport direction;
• and
• a bearing groove formed so that a shaft of the second roller moves in a direction diagonally forward than the vertical direction with respect to the transport direction along an inclined surface of the bearing groove, wherein
• the inclined surface of the bearing groove turns such that an inclination angle thereof is variable according to a force applied thereto due to hitting of the paper-sheets,
• a range of a turning angle of the bearing groove varies depending on thickness of a transported banknote,
• the second roller is brought into pressure contact with the first roller, and moves the banknote in a direction in which an impact, caused when the banknote hits a roller contact portion, is absorbed, and
• the inclination angle of the inclined surface of the bearing groove is variable such that the inclined surface can be made steeper or less steep as a result of the force applied thereto.
