    Abstract: A technique is provided which can improve optical characteristics by suppressing the occurrence of an error in attachment of a rotary deflector that deflects a light flux from a light source and scans it in a main scanning direction. There are provided a rotary deflector that deflects the light flux from the light source and scans it in the main scanning direction, an imaging optical system that images the light flux scanned by the rotary deflector onto a specified scanning object, a support part that supports the rotary deflector rotatably, and a positioning part that comes in contact with the support part at plural contact positions and positions the support part, in which a shortest distance between the plural contact positions in an optical axis direction of the imaging optical system is longer than a shortest distance between the plural contact positions in the main scanning direction.

    Abstract: Deformation of a second optical carriage (B) due to heat is large on a (C) side where an inverter (31) is attached and small on a (D) side. A mirror supporting portion inside the second optical carriage (B) supports the mirror at one point on the (C) side and at two points on the (D) side. An angle of the reflecting mirror (8) depends on two protrusions on the (D) side where thermal deformation is small, and the mirror is supported at one point on the (C) side where thermal deformation is large. Thus, even if an angle of the mirror supporting portion (C) changes, the angle of the reflecting mirror (8) is not affected. Therefore, a change in the angle of the reflecting mirror (8) can be controlled to be small when temperature of the second optical carriage (B) rises during a reading operation, and decrease in reading accuracy due to thermal deformation of the second optical carriage (B) can be suppressed.

    Abstract: An image reading apparatus includes a scanning unit disposed in a box-shaped casing for scanning a stationary original in a sub-scanning direction to read the original; a supporting unit for supporting one side of the scanning unit in a main scanning direction and guiding the one side of the scanning unit in the sub-scanning direction; a driving source for moving the scanning unit in the sub-scanning direction; a drive transmitting unit for transmitting a drive of the driving source to the scanning unit; and first and second reinforcing plates attached to the casing along the sub-scanning direction for reinforcing the casing. The first reinforcing plate forms a guide unit for supporting the other side of the scanning unit in the main scanning direction and guiding the scanning unit in the sub-scanning direction. The driving source and the drive transmitting unit are fixed to the second reinforcing unit.

    Abstract: An optical scanning apparatus includes a plate member, having a rotation axis and a reflection surface, that deflects and scans a laser beam emitted from a light source by performing reciprocating-rotation around the rotation axis, an actuator configured to drive the plate member, an fθ-lens configured to focus the laser beam deflected by the plate member on a surface of a photosensitive drum, and an optical box configured to house the plate member, the actuator, and the fθ-lens. The actuator is provided nearer to a side of the optical box toward which the laser beam is reflected by the reflection surface than the reflection surface of the plate member is.
