Abstract: An optical scanning device includes a light source, a light-beam splitting unit, a deflector, and a scanning optical system. The light-beam splitting unit splits a light beam from the light source into a plurality of light beams, so that the light beams are each incident to any one of reflecting surfaces of the deflector while having a phase difference of approximately π/2. The scanning optical system receives the light beams from the deflector and projects each of the light beams onto a corresponding target surface.

Abstract: In an image reading apparatus, a retreat control device moves a conveyance target through a conveyance mechanism, when a stop operation is performed by a stop control device, in an opposite direction to an image reading direction to a position further from a restart reference position set by a position setting unit. A reading control device again moves the conveyance target, which has been moved by the retreat control device, at a constant speed in the image reading direction under a predetermined condition; inputs a line start signal to a reading unit when an offset time set by a time setting unit has elapsed from a time point when the conveyance target reaches the restart reference position; and periodically inputs a line start signal to thereby cause the reading unit to perform a reading operation from a point; where the reading unit is located when the offset time has elapsed.

Abstract: Any one of a plurality of modes such as a scanner function, a copy function, a facsimile function and the like can be set, and an operation mode of an image reading unit at the time of its image reading operation is judged. A return speed of the image reading unit for returning to a reference position after completion of the scanning is set at a speed corresponding to the operation mode. As a result, a machine sound generated when the image reading unit moves does not cause a user to feel uncomfortable, and the waiting time until the next document reading can be shortened.

Abstract: An imaging lens good in mass-productivity, compact, low in manufacturing cost, good in aberration performance is provided by effectively correcting aberrations without greatly varying the variation of the thickness of a curing resin. An imaging device having such an imaging lens and a portable terminal are also provided. A third lens (L3) has a flat surface on the object side, a convex surface near the optical axis on the image side, and a concave aspheric surface around the peripheral portion within the region where a light beam passes. Therefore, it is possible to reduce the other optical aberrations such as distortion and simultaneously to design the imaging lens so that the astigmatism takes on a maximum value at the outermost portion. Hence, the resolutions at low to middle image heights are high. In addition, such a shape does not cause a large variation of the thickness of the third lens (L3) from the region along the axis to the periphery. Therefore, the thickness of the third lens (L3) can be small, and the material cost can be reduced.

Abstract: A write reference signal generating unit uses horizontal synchronization signals output from BD sensors to generate, for each laser scanning unit of respective image forming units, a main scanning write reference signal for irradiating laser light from a semiconductor laser every other predetermined number of reflective surfaces when photosensitive drums are driven to rotate at a second speed of rotation which is slower than a standard speed of rotation. A phase adjustment unit adjusts the phase of a control signal for driving a polygonal mirror, which is output to a polygon motor of each image forming unit, on the basis of a relative time difference between image write timings of the respective laser scanning units as measured by a time difference measurement unit.

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.
