摘要： A curl correcting apparatus includes rollers, a motor, and a clutch portion. The rollers are curl correction-use rollers which are arranged in parallel to each other in a pressure-contact state and which are different in hardness. The motor is a motor capable of rotating in forward and reverse directions relative to a correction-amount adjusting portion that changes and adjusts a distance to the rollers as a result of an eccentric cam that integrally rotates in accordance with a rotation amount of a rotation shaft, pressing against the rollers. The clutch portion transmits a rotary driving force of the motor to the rollers during the forward rotation and to a rotation shaft during the reverse rotation.

摘要： A sheet processing apparatus includes a pair of belts, a water supplying unit, a curving unit and a controller. The pair of belts defines a conveying path for holding and conveying a paper sheet. The water supplying unit supplies water to outer surfaces of the belts. The curving unit curves the conveying path defined by the belts. The controller makes the water supplying unit supply water to the outer surfaces of the belts, and makes the belts convey the sheet between the belts in a state where the conveying path is curved by the curving unit to correct the curling of the sheet.
