Abstract:
To simplify assembling of a BD mirror.
A principal part of scanning light L1 of a rotary polygon mirror 3 is image-formed on a photoreceptor not shown in the figure by a scanning lens 4. A part of the scanning L1 is separated as a scanning start signal by a BD mirror 5 at an end on the scanning surface and guided into the BD sensor 7.
