20100053714 | OPTICAL BOX, OPTICAL SCANNER, AND IMAGE FORMING APPARATUS - An optical box for an optical scanner includes an optical housing and a lid. The optical housing has an opening and a side wall surrounding the opening. The side wall includes inward recessed parts, each of which has a protrusion formed on its outer side. The protrusion can engage with the lid. The lid can so engage with the optical housing as to cover the opening of the housing. The lid has a pair of dust guard walls, between which the whole side wall of the optical housing is sandwiched when the lid is in engagement with the housing. | 03-04-2010 |
20100060965 | OPTICAL SCANNING APPARATUS AND IMAGE FORMING APPARATUS - In one embodiment of an optical scanning apparatus, a light blocking member is provided that is disposed facing a reflective face of a polygon mirror near the reflective face, and blocks stray light without blocking light in an effective scanning range of a laser beam. The light blocking member includes a light blocking plate having an opposing face that faces the reflective face of the polygon mirror, a support plate that supports the light blocking plate, and a fixing plate that fixes the lower edge portion of the support plate to a support member. The opposing face of the light blocking plate is inclined relative to the reflective face of the polygon mirror, and a space below the light blocking plate is open. | 03-11-2010 |
