发明名称 Image capturing apparatus for guiding light emitted from a plurality of light emitting devices
摘要 An image capturing apparatus illuminates an object and captures an image of the object using the reflected light from the object. On a circuit substrate mounted an image sensor, a plurality of light-emitting devices are mounted in the peripheral positions of the image sensor. By means of a ring-shaped light guide member, the light from the plurality of light-emitting devices is guided to an image capturing range, so as to illuminate the object. With this, by mounting a light receiving system and a light emitting system on an identical substrate, miniaturization can be achieved, and the image capturing range can be illuminated by substantially uniform light. Also, using the ring-shaped light guide member, an optical unit is housed inside the ring, thus enabling further miniaturization.
