CURL CORRECTING APPARATUS AND IMAGE FORMING APPARATUS

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.

主权项

1. A curl correcting apparatus, comprising:
a curl correcting portion that has a first roller and a second roller which are arranged in parallel to each other in a pressure-contact state and which are different in hardness; an adjusting portion that includes an adjustment rotation shaft having an abutting portion and that adjusts a distance to the first roller as a result of the abutting portion pressing against, in accordance with a rotation amount of the adjustment rotation shaft, the second roller; a rotary driving portion capable of rotating in forward and reverse directions; and a clutch portion that transmits a rotary driving force of the rotary driving portion to the first roller during the forward rotation and to the adjustment rotation shaft during the reverse rotation.
