Patent number: 8035677Abstract: In an optical scanning apparatus, when air flow from a deflecting device is suppressed by a shielding member such as a transparent member, an image of a light beam is not formed at a predetermined position. In view of this, a first wall portion having a wall surface shaped concentrically with a center axis of a deflecting device is provided on an optical path directed from a laser light source toward the deflecting device. By providing at least the first wall portion having laser beam passing portions as openings passing through the wall surface of the first wall portion and providing a second wall portion connected to the first wall portion to define a closed surface except for the laser beam passing portions, warm air flow directed from the deflecting device to the laser light source is blocked.Type: GrantFiled: February 20, 2009Date of Patent: October 11, 2011Assignee: Canon Kabushiki KaishaInventor: Kazuo Uduki

Patent number: 8027075Abstract: An optical scanning unit used for scanning a photoconductor includes a light source, a rotatable deflector, a driver, a scan lens, an optical element, a first casing, a second casing, a first cover, and a second cover. The rotatable deflector deflects a light beam generated by the light source to scan a surface of the photoconductor. The driver rotates the rotatable deflector. The scan lens converts the light beam deflected by the rotatable deflector with equiangular motion speed to a light beam having constant speed motion. The optical element is disposed along an optical path from the scan lens to the photoconductor surface. The first casing houses the light source, the rotatable deflector, and the scan lens. The second casing houses the first casing and the optical element. The first cover covers at least the first casing. The second cover covers the optical element housed in the second casing.Type: GrantFiled: March 4, 2008Date of Patent: September 27, 2011Assignee: Ricoh Company, Ltd.Inventor: Keiichi Serizawa
