Abstract: An optical scanning device includes a light source portion, a deflector, a first scanning lens, a second scanning lens, and a pair of reflection mirrors. The first scanning lens collects a light beam having been reflected by the deflector. The second scanning lens causes the light beam having passed through the first scanning lens to form an image on a circumferential surface of an image carrier. The pair of reflection mirrors, on an image formation optical path of the light beam, reflect the light beam having passed through the second scanning lens toward the image carrier. The light beam having been reflected by the pair of reflection mirrors passes between the first scanning lens and the second scanning lens to travel toward the image carrier.

Abstract: An image reading apparatus is provided with a carriage accommodating an optical unit for image reading, a driving member for moving the carriage, a guide rail, a guide-rail engaging portion engaged with the guide rail, a holding portion for holding the driving member, a guide plate and a claw portion. The claw portion presses the guide-rail engaging portion against the guide rail by partially deforming the driving member to produce a tensile force in the driving member and causing the tensile force to act on the first end portion of the carriage, and produces such a rotation moment for biasing the first end portion of the carriage in a first direction parallel with a sub scanning direction and, on the other hand, biasing the second end portion of the carriage in a second direction opposite to the first direction and parallel with the sub scanning direction.

Abstract: A copy machine is provided which includes: a fluorescent lamp; a mirror group having a plurality of mirrors that forms a light path by reflecting luminous flux from an original once on each of the plurality of mirrors, and is configured so that an imaging-side mirror, which is disposed most to an imaging side on the light path, has a shortest length in a main scanning direction; an imaging lens that forms an image from luminous flux reflected by the mirror group; a reading portion that reads an image on the original based on image formation by the imaging lens, disposed in an imaging position of the imaging lens; and a casing body that houses the fluorescent lamp, the mirror group, the imaging lens, and the reading portion, to be movable in a sub-scanning direction that is orthogonal to the main scanning direction.

Abstract: An unit is provided with a friction member which is disposed at a position that is on a downstream side of a drive roller driving a belt and is on an immediate upstream side of a position sensor. The friction member wipes off contaminants adhering to a rear surface of the running belt, thereby constantly keeping the rear surface clean, and therefore, no toner scatters to the sensor. Further, the friction member gives a moderate tension to the belt, so that the posture of the belt is stabilized at a position where it passes the sensor, resulting in enhanced detection accuracy of the sensor.
