Abstract
A contactless image sensor comprises a light source for irradiating the light onto an original, photoelectric converting elements for photoelectrically converting the light from the original, an image pickup device for guiding the light from the original to the photoelectric converting elements, and a frame body for holding them. The frame body includes a light transmitting portion and a light non-transmitting portion, which are integrally pressing-out molded plastics. That is, the optical path portion and the optical guide of the frame body are made of transparent plastics and the other portions of the frame body are made of colored plastics having a light shielding performance.
