An image forming apparatus includes a photosensitive member, a light source, a deflecting unit, a storing unit, a correcting unit, and a light source driving portion. Magnification correction data is determined using a quadratic function of a variable representing a scanning position with respect to a scanning direction. Coefficients of two quadratic functions corresponding to adjacent two regions included in a plurality of scanning regions are set so that a differential value calculated at the variable corresponding to a boundary of the two regions by a differential of the quadratic function for one region and a differential value calculated at the variable corresponding to the boundary of the two regions by a differential of the quadratic function for the other region are equal to each other.

There is disclosed an apparatus and method of aligning content put through a duplex scanner. By performing operations on data extracted from physical documents, digital documents that would otherwise appear skewed can be un-skewed. The process compares two images, e.g. a front and a back page for a document, and determines how they are offset from one another. The process uses a projection profile error minimization technique to calculate a translation for one or both pages to digitally align the margins for a digital document such that the margins match.

An image reading device includes a plurality of light-receiving pixels configured to receive reflected light; a first light-shielding member including a plurality of first openings and disposed between the plurality of light-receiving pixels and a reference surface; a second light-shielding member including a plurality of second openings and disposed between the plurality of first openings and the reference surface; and a plurality of condenser lenses disposed at a distance from the plurality of second openings. The plurality of condenser lenses, the second light-shielding member, the first light-shielding member, and the plurality of light-receiving pixels are disposed at positions at which reflected light sequentially passes through one of the condenser lenses corresponding to each light-receiving pixel, one of the second openings corresponding to the each light-receiving pixel, and one of the first openings corresponding to the each light-receiving pixel and enters the each light-receiving pixel.

A portable terminal including a battery accommodating section having an opening for battery insertion and removal which is provided at a position shifted to one end of a terminal main body on a predetermined surface of the terminal main body, a battery cover for covering the opening, and a switch section provided closer to an other end of the terminal main body than the battery accommodating section, on the predetermined surface of the terminal main body, in which the battery cover is provided extending from the one end to a position beyond the switch section.

A digital microform imaging apparatus includes a bracket movably coupled to a chassis. A microform media support is coupled to the bracket and includes a frame and a window supported by the frame. An illumination source is provided to direct light through the window of the microform media support along an optical axis. An optical sensor is positioned along the optical axis. A motor is operatively engaged with the microform media support to move the bracket and frame relative to the chassis along an axis perpendicular to the optical axis.
