摘要： The present invention provides methods and apparatus for adjusting the resonant frequency, scan velocity or other parameters of a pivotally functional surface such as an oscillating mirror used as the scanning engine of a laser printer or projection display. The selected parameter is adjusted by the application of tensional or compression stress to the torsional hinges of the mirror. According to one embodiment, the appropriate stress is generated by a slice of piezoelectric material bonded to the mirror device itself or to other portions of the support structure of the scanning engine.

摘要： It is an object of the present invention to realize a multi-beam optical scanning device which is suitable for high speed and high recording density by almost completely offsetting and correcting a deviation of focusing positions in a main scanning direction of plural spots in an entire surface to be scanned without deteriorating focusing properties at all. The multi-beam optical scanning device includes: a light source device 1 having plural luminescence parts; a rotating polygon mirror 5; a first optical system 2 which converts plural light beams into convergent light beams or divergent light beams; and a third optical system 6 which guides the light beams onto a surface to be scanned 7 of a drum shape, and when it is assumed that a maximum value of a positional deviation amount generated in a first direction is δY1, a maximum value of a positional deviation amount generated in a second direction is δY2, and a maximum value of a positional deviation amount generated in a third direction is δY3, conditional expression (1) is satisfied.

摘要： An optical scanning apparatus which does not require a complex shaped lens and which is capable of eliminating the bow of a beam light even when the shapes of a plurality of correcting lenses are unified by setting a shape of a sub-scanning cross-section of a scanning lens as a spherical surface when an incident angle condition to incident beam light is an angle of 2° or less against a cross-section which is at right angles to a rotational axis of a polygonal mirror. The curvature of an incident surface and an outputting surface of the scanning lens in the sub scanning direction is monotonically changed according to the position in the main scanning direction with respect to the distance from the predetermined center position in the main scanning direction.

摘要： A multi-beam scanning apparatus includes a light source having first and second light source sections that hold a pair of semi-conductor laser diodes and coupling lenses that couple four beams irradiated from the pair of semi-conductor laser diodes with a base member. A light beam deviating device may be provided so as to deviate the four beams. A scan imaging device is also provided so as to scan a scan receiving surface with beam spots of the beams deviated by the light beam deviating device. A beam pitch-detecting device is also provided so as to detect a beam pitch of the respective beams formed on the scan-receiving surface. A beam pitch correcting device is provided in order to correct the beam pitch by causing relative deviation of a light axis among the respective beams on a sub scanning direction cross sectional plane.
