ABSTRACT:
An optical scanning device includes an oscillating mirror portion having a reflection surface, and a frame portion holding the oscillating mirror portion. The optical scanning device reflects an incident optical flux by the reflection surface so as to convert the incident optical flux into a scanned optical flux. The optical scanning device further includes a reflection portion having a first reflection surface and a second reflection surface which are arranged in substantially V-shaped inclined surfaces. The first reflection surface reflects the incident optical flux and radiates the reflected light toward the oscillating mirror portion. The second reflection surface receives the reflected light from the oscillating mirror portion and radiates the reflected light as the scanned optical flux.
