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.

Abstract: An exposure apparatus emits a number of laser beams to the predetermined positions on a single photosensitive drum. Galvano-mirrors are employed for controlling the distances between the laser beams in the main scanning direction and the sub-scanning direction. The angles of the mirrors of the galvano-mirrors are adjusted in such a manner as to eliminate the adverse effects caused by a drift, such as variations in the viscosity of the dampening agent of a mirror driving mechanism and variations in the magnetic force generated by a magnetic circuit. Without such adverse effects, the laser beams can be guided accurately to the predetermined positions on the photosensitive drum. The angles of the mirrors are monitored by checking whether the laser beams are incident on the predetermined positions on the detection areas of a beam position sensor.

Abstract: An object of the invention is to reproduce a faithful image irrespective of thermal expansion of a light-scanning unit and to reproduce a faithful image without enhancing the strength of the light-scanning unit excessively. A pair of supporting portions of a light-scanning unit, each having a flat face, are supported in linear contact with a right column-shaped supporting member provided with the apparatus body. The light-scanning unit is provided on the supporting member near to a starting position where writing image data on a photosensitive body with a scanning line is started in a main scanning direction so as not to be mutually displaced relative to the supporting member. Thereby, the light-scanning unit is allowed to extend in the longitudinal direction of the supporting member due to thermal expansion of the light-scanning unit. Also, an elongated supporting member made of stainless steel penetrates a base body of a light-scanning unit made of synthetic resin which scans in scanning line of laser light on the photosensitive body to exposure, to support the light-scanning unit. The center of gravity of the light-scanning unit is positioned near to the supporting member and vertically below the supporting member, to make the moment acting on the light-scanning unit small and hold the light-scanning unit in a stable state. The supporting member suppresses deformation of the base body due to thermal expansion.

Abstract: PURPOSE: A method for controlling a motor in an image reading apparatus is provided to optimize the driving current of a motor which moves a scanning module. CONSTITUTION: A step motor is forwardly rotated to move a scanning module, and an output signal of a home sensor is read out(301). After reading the output signal of the home sensor, it is judged whether or not the scanning module is deviated from a home place(302). If the scanning module is placed at a predetermined position after a certain time, a controller stops the step motor(305). After the step motor is stopped, the control unit reversely rotates the step motor(306).

Abstract: An image reading apparatus includes a carriage having mounted thereon a linear light source and an image sensor and a reference pattern member disposed at a reference position located toward the first direction from a home position. The current location of the carriage is judged relatively to first and second areas that are divided by a boundary defined in advance at a location toward the first direction from the reference position. The first area is located toward the first direction and the second area is located toward the second direction. Immediately after the power is turned ON, current location information indicating whether the carriage is currently located in the first area or the second area is read from the nonvolatile memory. The carriage is first moved to the reference position and then moved a predetermined distance in the second direction, so that the carriage is duly positioned at the home position.
