摘要： In a line sensor including color filters that are periodically disposed in a light-receiving-element row, a problem called a “mixture of colors” occurs. A “mixture of colors” occurs when light that has been transmitted through a color filter differing from a color filter corresponding to a light receiving element is incident upon the light receiving element.In a CMOS sensor 107 including a light-receiving-element row in which a plurality of photodiodes 1204 are disposed side by side in a main scanning direction and a plurality of color filters 1202 that are disposed in correspondence with the plurality of photodiodes 1204, the center of each color filter 1202 is displaced in a direction of the center of the light-receiving-element row from the center of the photodiode 1204 corresponding to the color filter.

摘要： A light emitter includes an elongated substrate and a plurality of emission elements on the substrate. The emission elements include a first electrode, an organic layer, and a second electrode in this order from the substrate side. The organic layer stretches over one of the emission elements and a next one in the longitudinal direction of the substrate. The light emitter further has a plurality of projections on the substrate. Each of the projections is adjacent to each of the emission elements in the transverse direction of the substrate. The emission elements are located between one of the projections and another. The projections are higher than the second electrode with respect to the principal surface of the substrate. The projections and the second electrode are spaced from each other.

摘要： A reading control apparatus that causes a reading apparatus including a light source and a sensor configured to receive light reflected by an original, to read the original, executes control for changing the irradiation angle of the light source with respect to the original. The control is executed to change the irradiation angle for one light source. Read images of the original corresponding to respective changed irradiation angles are acquired based on reflected beams that correspond to the respective irradiation angles and have been received by the sensor. The region of a correction target on the original is detected based on the acquired read images.

摘要： An image forming apparatus employing an illuminator configured to irradiate light to a photosensitive body to change a level of electrical potential of the photosensitive body. The illuminator includes at least one light source configured to generate light and a light guide configured to guide the light received from the light source toward the photosensitive body. The light guide includes at least one incidence face and an emission face. The at least one incidence face faces the light source in a main scanning direction to receive the light from the light source into the light guide. The light exits from the light guide through the emission face toward the photosensitive body. The emission face includes a diffusion pattern having a plurality of semi-cylindrical structures along a width direction of the light guide. A radius of curvature of the semi-cylindrical structures increases away from the at least one light source.
