Abstract: A multi-beam scanning system for scanning a curved imaging surface includes at least one radiation emitter which emits first and second beams of radiation. A spin deflector, rotatable about a spin axis, directs the first beam to form a first scan line and the second beam to form a second scan line on the imaging surface. A deflection element, disposed in the path of the first beam and upstream of the spin deflector, operates to deflect the first beam with respect to the rotation of the spin deflector. The spin deflector is impinged by beams of radiation only at a distance, other than zero, from the spin axis.

Abstract: A beam spot detector is disposed on an extension of a surface to be scanned by a beam of light. The beam spot detector has a mask in front thereof, the mask having a side which the beam of light intersects perpendicularly and a side which the beam of light intersects obliquely. An output signal of the detector is differentiated at a differentiating circuit, and positive and negative peak values are held at a peak hold circuit. A CPU calculates diameters of the beam of light in both a main scanning direction and an auxiliary scanning direction from the peak values. If the beam of light is out of focus, then the CPU outputs adjustment signals. A counter calculates a width of the output signal of the beam spot detector and outputs the calculated width to a CPU. The CPU compares the received width with a reference to detect a displacement in the auxiliary scanning direction (displacement of registration) and outputs a correction signal.

Abstract: A method and apparatus is provided for line scanning a beam receiving member, wherein a scanning beam is angularly or laterally displaced to compensate for scan line spacing error. The beam is displaced according to error arising from variation (flutter) in the relative motion of the beam and the beam receiving member, or according to error arising from movement of the receiving member while the scanning beam travels to a start of scan position, or both. Embodiments of beam displacement means include a refracting tilt plate, a reflecting tilt plate, a diffracting tilt plate, and a tilt prism.

Abstract: In a laser printer wherein a photoconductive drum is scanned by utilizing a plurality of laser beams, there are detected spacings between the plural laser beams, such detection being confined to a blanking time. On the basis of the detected results, the spacings between the plural laser beams are controlled; and this state is maintained for a printing time. With this arrangement, it is possible to accurately detect the spacings between the plural laser beams thereby to obtain the practicable laser printer employing the plural laser beams.

Abstract: The disclosure pertains to an apparatus for recording an image on a film in a scanned horizontal line pattern with a light beam, the scanned pattern being achieved by reflecting the light beam from a moving surface such as an optical spinner. There is disclosed a subsystem for improving the vertical registration of successive lines in the pattern. Means are provided for sensing the beam position at the beginning of a scanline and for developing a position-indicative signal which varies in accordance with the relative vertical position of the beam. The position-indicative signal is compared to a predetermined reference signal which is a function of the desired position of the beam and there is generated a correction signal which depends on the comparison. Further means are provided for vertically deflecting the beam in accordance with the correction signal.
