Abstract
The scanning optical device (6) includes a light source, a deflector (30) configured to rotate on a horizontal surface around a rotating shaft extending in a vertical direction and an optical box (50) in which the light source, the deflector (30), and the optical components groups (40) are housed and supported by the frame (60). A heat sink (36) is disposed between the deflector (30) and the frame (60). A first protrusion (37) extending on an extension line of the rotating shaft of the deflector (30) is formed in the heat sink (36). A first engaging hole (61) with which the first protrusion (37) engages is formed in the frame (60).
Claims12
An image forming apparatus comprising:
- a scanning optical device;
- and
- a frame to which the scanning optical device is mounted,
- the scanning optical device including:
- a light source;
- a deflector configured to rotate around a rotating shaft extending in a vertical direction to deflect light emitted from the light source;
- optical component groups configured to be disposed around the deflector and to focus the light deflected by the deflector on a surface of an image carrier;
- and
- an optical box in which the light source, the deflector, and the optical components groups are housed, the optical box being supported by the frame,
- wherein a heat sink is disposed between the deflector and the frame,
- a first protrusion extending on an extension line of the rotating shaft of the deflector is formed in the heat sink, and
- a first engaging hole with which the first protrusion engages is formed in the frame.
