Abstract: A photographic scanner has a light source for illuminating a photographic original to be scanned and a sensor for detecting light which has passed through the original. The sensor has a single row of sensing cells, and the original is scanned by moving the sensor and the original relative to one another in a direction perpendicular to the row. An objective serves to focus light from the original on the sensing cells. Between the objective and the sensor is a protective glass sheet which overlies the sensor. A mask is interposed between the protective sheet and the sensor and has a slit in register with the row of sensing cells. The mask reduces the amount of scattered light reaching the sensing cells.

Abstract: A reading surface of a document is illuminated by a light source, and a light beam reflected on the reading surface is reflected on a reflecting mirror. Then, the reflected light beam is guided in such a direction as to pass in the vicinity of a light shielding plate for shielding the constitutional elements from the light. A lens is located near the light source at a position where the light beam guided in the above direction is allowed to pass. A shading correcting device is made up of a first shading correcting portion formed by a part of the light shielding plate and a second shading correcting portion formed in a body case for holding the constitutional elements. The shading correcting device is designed to restrict a more quantity of light of the light beam incident upon the lens at a portion nearer to an optical axis of the lens. A photoelectric correcting device is provided in a position where the light beam passing through the lens is focused. As a result, photoelectric converting elements in the photoelectric converting device receive an equalized quantity of light of the light beam. A part of the shading correcting device for equalizing the quantity of light of the light beam incident upon the photoelectric converting means is formed by utilizing the light shielding plate. Accordingly, the number of parts may be reduced, and the assembling work may be simplified.

Abstract: An image reader in which sensitivity fluctuations of a solid-state image pickup device are eliminated. The imaging rays of a picture to be read are applied with diffusion to the surface of the solid-state image pickup device. The diffusion may be supplied by the use of a diffused light source such as a fluorescent lamp, a number of spot light sources, or a tungsten light source with a diffusing plate. Otherwise, the incident light can be diffused immediately adjacent the surface of the solid-state image pickup device with a light-diffusing plate.

Abstract: There are provided a lens barrel, an imaging device body, and an imaging device that can reduce a deviation in a blurred image of oblique luminous flux caused by an APD filter.A lens barrel includes a first lens optical system and a second lens optical system serving as lens optical systems including focus lenses, a diaphragm that changes the amount of an incident ray and emits the incident ray, a first APD filter that is disposed on a light-incident side of the diaphragm, and a second APD filter that is disposed on a light-emitting side of the diaphragm. Since the amount of a reduced upper ray L1 of oblique luminous flux and the amount of a reduced lower ray L2 thereof are made to be substantially equal to each other by the first APD filter and the second APD filter, a deviation of a blurred image is reduced.
