    Abstract: A document reading unit constituting an MFP reciprocates a reading glass holder in a direction of a vertical scanning at a low frequency (18 times per second) with use of a crank mechanism including a motor and gears. A stroke length of the reciprocating motion of a reading glass is 9 mm. This structure can make a line-shaped noise less noticeable, because a length of each portion of a line-shaped noise becomes 2.57 mm and a distance between adjacent portions of the line-shaped noise becomes 7.27 mm when a foreign object having a diameter of 100 μm adheres to the reading glass.

    Abstract: The object of this invention is to read an image (scan flow), when an original is being moved, above a scan flow glass member, so as to prevent degradation in image caused by dust or a scar on a scan flow glass. In order to achieve this object, the original which is being moved is illuminated by an illumination system comprised of an illumination light source and reflecting member and different from an illumination system in a reading apparatus body and comprised of an illumination light source and reflecting member. After a reflected light beam passes through a slit and the scan flow glass member, it forms an image on a line sensor, e.g., a CCD, by an imaging lens through a movable mirror. As the original moves at a constant speed, it is read by the line sensor, e.g., a CCD, at a predetermined timing, thereby obtaining image information of the original. The original is located above the scan flow glass member. Even if dust or a scar of about several tens μm is present on the scan flow glass member, it goes out of focus, so it can be prevented from forming an absent point of the line sensor such as a CCD.

    Abstract: A light-guide module is used for guiding the incident light to a process device. The light-guide module comprises an entrance and a plurality of reflected mirrors. The entrance is provided for entering the signal light. The reflected mirrors are arranged as a predetermined light route for guiding out the signal light. One of the reflected mirrors comprises a light shielding structure for preventing the noise reflecting from the reflected mirror so as to prevent the noise light from entering the image sensing device and to prevent the image sensing device to process the noise.

    Abstract: A device for driving an endless belt of the present invention includes a drive roller and a roller pair adjoining the drive roller at a side where a photoconductive element is positioned and contacting the belt. The eccentricity of the drive roller and that of the roller pair are reduced to reduce the variation of belt speed when the drive roller is controlled at a preselected angular velocity. Even when the drum is eccentric, the device stably operates integrally with the belt without any slip or oscillation.

    Abstract: A plurality of cathode lines are formed as scanning electrodes on a transparent substrate, and metal cathodes of the same cathode line apply a common potential to organic electroluminescence elements that are arranged in a main-scanning direction in the same element row. A plurality of anode lines are formed as data electrodes on the transparent substrate, so as to intersect the plurality of cathode lines and incline at a predetermined angle &thgr; with respect to a sub-scanning direction. Transparent anodes of the same anode line apply a common potential to organic electroluminescence elements having mutually different positions in the sub-scanning direction. Organic electroluminescence elements that use the same anode line have mutually different positions in the main-scanning direction. Organic electroluminescence elements that have the same position in the main-scanning direction use mutually different anode lines.
