    Abstract: The image reading apparatus conveys a reading unit or a document to read the document. Conveyance is implemented by motor control based on a target position trajectory. The reading unit reads the document each time a line start signal is inputted. When a predetermined condition is satisfied, the reading operation is invalidated. A conveyance position at a timing to start the first reading operation invalidated is specified as an interrupted position. The object is arranged at a conveyance restart position moved back from the interrupted position. A target position trajectory is newly set. A conveyance time from the conveyance restart position to the interrupted position defined by the target position trajectory is an integral multiple of an output cycle of the line start signal. The motor control based on the target position trajectory is started at a timing coinciding with an output timing of the line start signal.

    Abstract: According to the present invention, highly accurate adjustment of the angles and positions of optical elements constituting an optical scanning unit can be easily performed.For a cylindrical lens that makes the light beam for exposing a photoreceptor converge on the surface of the photoreceptor, a frame is provided for holding the cylindrical lens therein. The frame is supported by two support portions for a chassis of the optical scanning unit such that the longitudinal direction of the cylindrical lens becomes parallel to the scanning direction of the photoreceptor. The optical scanning unit is configured such that the angle of the cylindrical lens in the longitudinal direction is adjustable in the sub-scanning direction of the photoreceptor at the support portion on the front side (operational side) of these support portions.

    Abstract: An image scan apparatus includes a scanner including: a document table on which a document is placed; a carriage which scans a read area of an image; a stepping motor which moves the carriage; an image processing unit which processes an image signal resulted from scanning by the carriage; a scanner controller which performs a process necessary to read the image; and memory which stores information, wherein on the document table, a sub-scan magnification adjustment chart which expresses a predetermined shape in order to calculate an actual sub-scan magnification by the scanner controller is placed. According to the image scan apparatus, when error occurs in the actual sub-scan magnification, the sub-scan magnification can be automatically adjusted without an operator performing the adjustment work of the magnification in the sub-scanning direction.
