Abstract: In a contact-type image sensor according to the present invention, a protrusion is formed in a transparent plate, a recess is formed in a sensor frame, and the transparent plate is engaged with the sensor frame so that the heights of surfaces of the transparent plate and the sensor frame on sides of conveying a manuscript are substantially the same. In conventional techniques, it was necessary to bend a manuscript conveying path because of different heights of a protrusion of the frame and the transparent plate. Further, even though the heights of the sensor frame and the transparent plate are the same, a contact portion therebetween forms an angle, whereby a contact surface is not brought into close contact alone an entire length of an image sensor, and gaps are partially formed in the contact surface. Therefore, at time of cleaning a surface of the transparent plate using a solvent such as alcohol to remove dirt on the transparent plate, the solvent and extraneous matters intrude inside the image sensor from the gaps, a passage of light is obstructed, and therefore light-and-shadow information of an image of the manuscript was not correctly transmitted to sensor.

Abstract: An optical scanner system wherein the central region of the light source is selectively covered up by a mechanically actuated shutter during a transparency scanning mode. By occluding the central portion of the light source, problems with flare and degraded image quality are eliminated. The shutter is actuated to its two positions (normal reflective mode position, transparency mode position) by pins, protrusions, or the scanner walls in the scan module path. When the scan module is driven to the extremes of its travel the shutter is either driven open or closed. A bracket structure is provided to hold the transparent media and a covering light reflective tent, and can include the pin or pins that can protrude into the scanner module path and thus actuate the shutter only when the structure is mounted on to the scanner by the user. The bracket structure can include a lower member that rests directly on the platen glass to align filmstrips, slides, and other transparent media. The tent structure is hinged relative to the lower structure which allows it to be opened and closed to enable insertion of transparent media. When the tent structure is closed it acts as the reflective light path to allow light from the primary light source to be reflected up, over, and down through the transparent media, and into the optical light path leading to the optical sensor.
