摘要： In one example, an apparatus includes a transparent platen to receive a document to be scanned. The transparent platen includes a scan line, an ingress edge positioned prior to the scan line in the document path, and a chamfered egress edge positioned subsequent to the document path. A light source is positioned to illuminate the document with light while the document passes across the scan line, and a focusing mechanism is positioned to focus a portion of the light that is reflected by the document onto a sensor that senses the portion of the light.

摘要： An exposure device includes a first light emitting element substrate including a plurality of first light emitting elements arranged at an arrangement interval T in a longitudinal direction, and a second light emitting element substrate including a part in the longitudinal direction that overlaps with a part of the first light receiving element substrate so as to form an overlapping region. The first and second light emitting element substrates are shifted from each other in a direction perpendicular to the longitudinal direction. The second light emitting element substrate includes a plurality of second light emitting elements arranged in the longitudinal direction. The second light emitting elements are arranged at the arrangement interval T at least outside the overlapping region. When an interval between two of the second light emitting elements of the second light emitting element substrate disposed in the overlapping region is expressed as a specified interval TS, the specified interval TS and the arrangement interval T satisfy: T≤TS≤2T.

摘要： An image reading device includes: an FB glass; a sensor module having a light source and a plurality of sensors; and an image processor that generates correction data to be used for shading correction and performs the shading correction on image signals by using the correction data. The plurality of sensors is arranged in a main scanning direction and is configured to form an image signal on a single line. The image processor acquires second black data by causing the plurality of sensors to acquire an image signal of a reference sheet placed on the FB glass with the light source turned on, and generates black correction data based on the second black data. By performing the shading correction by using the black correction data, the image processor corrects density unevenness, in an image, caused by interference between image signals from the plurality of sensors.
