Patent number: 6032009Abstract: In an image reading apparatus, an image is illuminated to be guided as a light beam to a photosensitive drum through an image forming lens. Light amount correcting members are attached to a movable member movably attached relatively to the image forming lens. The movable member moves in the optical axis direction in accordance with movement of the image forming lens, and one of the light amount correcting members farther from the image forming lens is caused to face a corresponding surface of the image forming lens so as to intercept a part of the light beam from the image in association with the movement of the movable member. The other of the light amount correcting members closer to the image forming lens is caused to retract from a corresponding surface of the image forming lens in association with the movement of the movable member.Type: GrantFiled: September 8, 1998Date of Patent: February 29, 2000Assignee: Canon Kabushiki KaishaInventors: Nobumasa Fukuzawa, Yoshiyuki Koshimizu

Patent number: 5905934Abstract: An apparatus has a first conveyor for conveying a recording medium into an image forming unit which forms an image on a recording medium, a second conveyor for re-conveying the recording medium having an image formed thereon by the image forming unit to the second conveyor, and a curl straightener, formed by a plurality of rollers forming a bent path within the second conveyor, for straightening the curl on the recording medium. The conveyance speed of the second conveyor is switchable between a first speed equal to the conveyance speed of the first conveyor and a second speed which is greater than the first speed. The first speed is the speed of the recording medium until at least a predetermined length of the recording medium passes the curl straightener, and the second speed is the speed of the recording medium after passage therethrough.Type: GrantFiled: May 14, 1997Date of Patent: May 18, 1999Assignee: Canon Kabushiki KaishaInventor: Yoshiyuki Koshimizu
