<p>An ADF includes an ADF main body portion, a scanner frame, a gear portion, a resistance gear, a torque limiter, and an outer cover. The scanner frame is supported at the ADF main body portion so as to be rotatable. The gear portion is arranged on a rotation axis line of the scanner frame so as to integrally rotate with the scanner frame. The torque limiter applies resistance to the resistance gear that gears with the gear portion when the scanner frame rotates from an exposed position to a usage position. The outer cover is attached to the ADF main body portion so as to cover one part of the gear portion. The outer cover includes a contacting portion for regulating the movement of the gear portion.</p> |
