摘要： A laser beam scanning system includes a laser for emitting a laser beam modulated with image information to be recorded and a deflecting device, such as polygon mirror, for deflecting the laser beam over a predetermined angle repetitively, so that the laser beam is scanned on a scanning surface, thereby an image is formed on the scanning surface. When a plurality of laser beams are used at the same time, the plurality of laser beams are arranged in an array inclined with respect to the scanning direction. In this case, a sync sensor generates a sync signal in response to a laser beam received in the first place. When a polygon mirror is so structured to have a reflecting surface which is defined by a curved surface having a predetermined radius of curvature, a f.theta. lens may be discarded. In this case, when a transparent layer is formed on this curved reflecting surface, no distortion in scanning speed is produced even without using any electrical correction. Besides, it is also preferable to control the intensity of laser beam so as to maintain the image density of a resultant image at constant.

摘要： A laser beam emitting apparatus includes a semiconductor laser, a photodiode for detecting the intensity of the laser beam, an amplifier for amplifying the detection signal from the photodiode, and a variable resistor connected to the amplifier for adjusting the gain of the amplifier. In one embodiment, these elements are provided in a unit structure so that the adjustment of the gain of the amplifier can be carried out in advance. In another embodiment, a collimating lens for collimating the laser beam emitted from the laser is also provided in the same unit. In another embodiment, a single-piece support is provided to support the semiconductor laser, the collimating lens, and an aperture plate formed with an aperture for shaping the collimated laser beam. As a modification, the single-piece support can be made dual in structure while maintaining the structural integrity of the support.

摘要： The speed at which a desired surface is scanned by a light beam is rendered constant by correcting the frequency of an image scanning clock signal without using an f lens. The characteristics of correcting the image scanning clock frequency can be varied, or the image scanning clock signal can be brought into phase with a recording position signal.

The scanner scans the surface by a light beam which is deflected at a constant or a non-constant angular velocity and without resorting to an F-theta lens. The scanning clock generating device generates a scanning clock the frequency of which is continuously variable responsive to changes of scanning velocity on the surface to be scanned.
