Abstract:
1. An image sensor unit comprising: a light source including a light emitting element on a light emitting surface; a light guide having a light incident surface and a light ejecting surface, the light incident surface being positioned facing the light emitting surface, wherein the light guide emits the light from the light ejecting surface and illuminates an object to be illuminated; an imaging element that images the light reflected from the illuminated object; a sensor substrate on which a photoelectric conversion element is mounted, wherein the photoelectric conversion element converts the reflected light imaged by the imaging element into an electric signal; and a frame that supports the light source, the light guide, the imaging element, and the sensor substrate, wherein the light source includes a first positioning sections disposed on an opposite side of the light emitting surface of the light source, wherein the frame includes a second positioning section disposed on a side facing the opposite side of the light emitting surface of the light source, wherein the first and second positioning sections are complementarily configured to fit together, and wherein the light source is disposed adjacent to one longitudinal end of the light guide so that the light emitting surface faces the light incident surface.
