Abstract: The invention provides, as an aspect thereof, an document reading apparatus that includes: a speed calculating unit that calculates a speed related to the rotation of a motor on the basis of a signal that is outputted from an encoder; and a controlling unit that calculates control amount on the basis of the speed calculated by the speed calculating unit so as to control the rotation of the motor in accordance with the calculated control amount. In the configuration of an document reading apparatus according to this aspect of the invention, the above-mentioned controlling unit controls the motor with an increase in the control amount in a case where there occurs no change in the signal that is outputted from the encoder for a certain period of time. The increase in the control amount is based on the length of time that has elapsed since the last change in the signal.

Abstract: Disclosed herein is a method of controlling a motor in an image reading apparatus. It may be possible to optimize the drive current of the motor for driving the movement of the scanning module by using information associated with, for example, the time it takes for the scanning module to return to a home or rest position after the scanning module is moved from the home position to a predetermined position. Such optimized drive current can result in improvements in the reading performance of an image by the image reading apparatus and reduction of power consumption.

Abstract: An image reading device reads an image of an original mounted on an original mounting base by using an optical scanning unit which is subjected to acceleration drive along the original mounting base until a velocity according to a reading magnification is obtained and then scanned by uniform velocity drive. A stepping motor moves the optical scanning unit. A reading magnification acceptance portion accepts a reading magnification of an image of the original mounted on the original mounting base. A motor drive control portion is used for control a drive electric current of the stepping motor, obliquely increases a set electric current during acceleration drive every velocity that the optical scanning unit reaches by a pulse number according to a reading magnification accepted by the reading magnification acceptance portion, and changes the set electric current value in accordance with the reading magnification so as to provide a characteristic for lowering the set electric current value at the time of shifting to uniform velocity drive. A photoelectric conversion portion converts a quantity of reflected light when the original on the original mounting base is optically scanned by the optical scanning unit moved by the stepping motor into an electrical signal.

Abstract: There is proposed a method and apparatus for multibeam scanning an inner face of a cylindrical drum, in which scanning lines are straightened under a simple control, and an interval between the scanning lines can be easily changed, thereby simplifying a constitution. In an embodiment, while keeping an interval between two light beams projected to an optical scanning system, the light beams are one-dimensionally deflected in mutually orthogonal directions in synchronism with a rotation of the spinner, respectively. In a second embodiment, one light beam is projected along a central axis common with the spinner and the cylindrical drum to the spinner. The other light beams are inclined in a plane including the central axis by a constant angle &phgr;y separately predetermined for each of the other light beams, and further inclined in a direction orthogonal to the plane including a rotation axis by an angle &phgr;x which is determined in synchronism with a rotation angle &thgr; of the spinner.
