LIGHT SOURCE DEVICE, OPTICAL SCANNING DEVICE, AND IMAGE FORMING APPARATUS

摘要

A light source device includes a light source that includes a vertical cavity surface emitting laser; a drive circuit that drives the light source; and a circuit board that includes at least one mounting surface on which the light source and the drive circuit are mounted. The light source is mounted on a first area of the mounting surface, the drive circuit is mounted on a second area of the mounting surface, and a highest end of the first area is at a same height or lower than a lowest end of the second area with respect to a gravity direction.
