摘要： There is provided an image sensor which can reduce loss in light emitted from a light emitting section toward an object to be sensed and also variability in the distribution of light and which can be produced with a small-sized structure with a reduced number of parts and with a decreased manufacturing cost. An optical path from the light emitting section to a transparent covering on which the object is to be placed is surrounded by a light reflecting portion. Light from the light emitting section can be irradiated onto the transparent covering without reduction in the amount of light while being repeatedly reflected by the light reflecting portion. The light reflected by the object is condensed by a condensing lens, the condensed light being then received by a light receiving section mounted on the same base plate as in the light emitting section. At the light receiving section, the light is converted into an electrical signal.

摘要： An image sensor has a frame including a reading window formed therein at the top of the frame. The reading window is closed by a glass covering which is adhered to the frame through an adhesive. First and second grooves are provided in the frame to extend along the reading window. After the adhesive has been charged into the first groove, the glass covering is placed and pressed against the frame top so that the glass covering will be adhered to the frame top through the adhesive. At this time, any excess adhesive may be received and held by the second groove.

摘要： An image sensor can easily adjust the focus by the use of an inexpensive focus adjusting means even if the dimensional accuracy in the image sensor frame is very low. In the image sensor or an optical character reader incorporating such an image sensor, an original document W, which is being conveyed onto a transparent covering by a platen roller, is irradiated by light from a light emitting element. The light reflected by the original document W is received and condensed by a rod lens array which is positioned perpendicular to the surface of the transparent covering. The condensed light is received by a light receiving element which is located directly below the rod lens array. At the light receiving element, the light is converted into an electrical signal. The image sensor includes a frame having an opened top which includes inner tapered sidewalls opposed to each other. When a transparent covering having the conventional configuration is to be mounted in the opened top of the frame, the focal length H can be easily adjusted by changing the inclination of the transparent covering relative to the opened top of the frame.
