Abstract
An imaging device includes a light source unit located so as to be inclined with respect to a medium conveying surface or a medium placing surface. The light source unit includes a light emitting element, a light guide provided with the light emitting element on a first end surface side, to guide light emitted from the light emitting element in a predetermined direction, and emit the light toward the medium from an emitting surface extending in the predetermined direction, and a reflector located around the light guide other than the emitting surface. The light guide includes a light diffusing surface on an opposite side to the emitting surface. The reflector does not cover a second end surface opposite to the first end surface of the light guide. A medium side surface of the reflector is located so as to protrude from the second end surface of the light guide.
