Abstract: A two-dimensional array include N light-emitting arrays each formed of M light-emitting units arranged equally spaced along a direction T tilting from a main scanning direction at an angle α toward a sub-scanning direction. The light-emitting arrays are equally spaced in the sub-scanning direction. A space ds2 between light-emitting arrays with respect to the sub-scanning direction satisfies ds2=ds1×M where ds1 is a positional difference in the sub-scanning direction between light-emitting units which are adjacent each other in the main scanning direction and orthographically-projected on a virtual line extending in the sub-scanning direction. The angle α satisfies α=sin−1((ds2/d1)/M) where d1 is a space between light-emitting units in the light-emitting array with respect to the direction T. The space ds2 is equal to the space d1.

Abstract: In an image reading apparatus that can read a reflection original and transparent original, a film holder for holding the transparent original is provided to be pivotal to the left or right about a shaft as the center. After the transparent original is set such that its image can be seen correctly, when the film holder is brought down to the right, the film can be set correctly concerning its upper and lower sides. At this time, as the film holder is held by the reading apparatus, its positional shift can also be prevented.

Abstract: Disclosed are embodiments of methods, systems, and apparatus for providing multiple image fields or regions on an imaging array. In certain preferred embodiments, a high density imaging array may be partitioned into two or more regions, each of which may be used to render a separate view of the scan volume. This arrangement may provide an increase in the effective scan volume beyond the volume available with a single imager having a single point of view and may allow for reading of encoded symbols at a variety of orientations that would otherwise preclude accurate imaging with a single imager.

Abstract: An image reading apparatus enabling a user to flexibly select one of plural reading modes, for example, for continuously reading two-sided images of stacked document sheets or reading pages of a book or a large document exceeding a platen. In a first reading mode, a reading unit scans a document and reads a document image. In a second reading mode, a stationary reading unit and the reading unit read an image of a document fed from a document feeder section. The reading unit is provided in a flatbed reading section which is detachable from an apparatus body. The flatbed reading section, when detached from the apparatus body, can be used as a flatbed scanner.
