る。The air in the cover flows at a high speed as the rotary polygon mirror rotates at a high speed, and flows out through the opening of the cover. The airflow flowing out from the opening swirls in the rotation direction of the rotary polygon mirror, and as it moves away from the outer peripheral surface of the rotary polygon mirror, a part of the flow velocity is lost and decelerated. Since a part of the opening is covered by the guide member, the air flow out of the opening that has a high flow velocity close to the rotating polygon mirror flows into the cover again along the first part of the guide member and rotates. What is decelerated away from the polygon mirror flows out along the second portion of the guide member. The wind noise is larger as the flow velocity of the air flow flowing out from the opening is higher. Therefore, the wind noise is reduced by preventing the air flow having a high flow velocity from flowing out of the opening by the guide member. In addition, since the airflow flowing out from the opening gradually decelerates while smoothly flowing along the second portion of the guide member, no vortex or the like is generated. Therefore, noise due to the vortex can be reduced. Further, the second portion of the guide member keeps the air flow out of the opening away from the lens or the like in the vicinity of the opening, thereby preventing the contamination. Further, the airflow flowing out from the opening can be cooled by blowing it onto a heat generating device such as a motor drive circuit which is close to the opening.

音が大幅に低減できることが判明した。When the rotary polygon mirror 1 rotates at a high speed, the air inside the cover 2 also flows at a high speed in the circumferential direction, and a part of the air is discharged from the window 3 to the outside. The airflow flowing out of the window 3 is swung in the rotation direction of the rotary polygon mirror 1 as shown by arrows W 1 to W 3 in FIG. 3, and both side edges 3 a, 3 of the window 3 are swung.
Negative pressure is generated in the vicinity of the side edge 3a on the upstream side in the rotation direction of b, and external air is sucked into the cover 2 as shown by an arrow W 4 . In the vicinity of the side edge 3 b on the downstream side of the window 3, the air flow flowing together with the rotary polygon mirror 1 is guided by the guide piece 4.
The airflow that is bisected by the first portion 4a of the rotary polygonal mirror 1 and flows at a high velocity near the outer peripheral surface of the rotary polygon mirror 1 flows into the cover 2 again as shown by an arrow W 5 , and the rest is guided by the guide piece 4a. Is discharged to the outside along the second portion 4c of the. That is,
The first portion 4a of the guide piece 4 extends upstream along the tangential plane A of the cylindrical portion 2a of the cover 2, so that its projecting end 4b is located radially outward of the cylindrical portion 2a of the cover 2. Because of this, the air flow that flows out to the outside goes away from the surface of the rotary polygon mirror 1, loses a part of the flow velocity obtained by the rotation, and is decelerated. Even if it collides with the projecting end 4b of the first portion 4a, a large wind noise is not generated. Further, the air flow that flows into the cover 2 again along the first portion 4a of the guide piece 4 is
Since it is gradually compressed along the inner surface of the first portion 4a of the guide piece 4, noise due to vortices and turbulence is extremely small. According to the experiment, it was found that the noise can be significantly reduced when the protrusion amount, which is the width of the first portion of the guide piece 4 in the protrusion direction, is 1/2 or more of the radius of the rotary polygon mirror 1.

It is smoothly guided by the second portion 4c, loses most of its flow velocity during this period, and diffuses into the surrounding atmosphere without generating a large wind noise or vortex.
