摘要： An optical power adjusting method and apparatus for preventing unevenness of exposure of a photosensitive material arising from the difference in wavelength of the light beams. The relationship between the output value and wavelength of the light receiving section is stored in a storage section for a light beam that satisfies the relationship with respect to the optical power and wavelength required for exposing the photosensitive material at a predetermined exposure level. The correspondence between the laser beam emitting section and its wavelength is stored in another storage section. Each laser beam is received separately by the light receiving section, and the optical power of each laser beam is adjusted by the optical power adjusting section such that the output value of the light receiving section for each laser beam received separately satisfies the relationship between the output value and wavelength.

摘要： The amount of exposure to a light beam is coarsely adjusted by a coarse adjusting unit which has a wider adjustment range, and finely adjusted by a fine adjusting unit which has a narrower adjustment range but a higher adjustment accuracy. With the coarse and fine adjusting units, the amount of light of the light beam for recording an image can be adjusted to a nicety by a relatively inexpensive arrangement.

摘要： The image recording method and apparatus are used to record an image formed by a group of light source elements disposed in a two-dimensional manner corresponding to recording pixels on a recording medium. In the image recording method and apparatus, an image recording position on the recording medium by the group of light source elements is moved in a direction that contains a component in at least one of two-dimensional disposing directions of the group of light source elements during the recording while modulating, in response to the movement, each recording pixel of the group of light source elements in accordance with an image to be recorded to thereby record the image on the recording medium. The image recording position is moved in accordance with a set magnification for changing the resolution par recording pixel of the group of light source elements. Further, the image recording position is moved by giving a relative speed difference between the relative movement of the group of light source elements and the recording medium and the tracking of the relative movement made by the image recording position by the group of light source elements.

摘要： The image recording method and image recording apparatus synchronize phase of a light deflector with rotation of a drum in response to the drum start point detection signal generated each time the drum rotates once, expose the two-dimensional image of one frame formed by a group of light sources disposed two-dimensionally onto the recording medium while causing the image at rest on the recording medium relatively thereto, thereafter move the optical system in the auxiliary scanning direction by an integral multiple of a pixel pitch forming one frame as well as deflect an angle of the light deflector in the main scanning direction by one frame so as to expose the next frame and on for one rotation of the drum. When the position is dislocated in the auxiliary scanning direction at the time the recording medium is to be exposed in a subsequent one rotation of the drum, the method and apparatus correct the dislocation of the position in the auxiliary scanning direction by changing an auxiliary scanning movement speed in a non-exposure time zone between the previous and subsequent rotations of the drum.Accordingly, the method and apparatus can prevent the occurrence of streaked unevenness in the surface exposure and spiral exposure.

摘要： In an image drawing apparatus and an image drawing method for forming a desired two-dimensional pattern on an image drawing surface by using a plurality of image drawing heads, uneven density and resolution caused by errors in relative positions of the heads and installation angles thereof and by an effect of pattern distortion can be reduced. A rectangular two-dimensional pixel array is installed in each of exposure heads in an exposure apparatus (image drawing apparatus) so as to make a predetermined angle with the direction of scanning, facing an exposure surface of a photosensitive material. Combinations of slits and photo detectors detect positions of light spots in the exposure surface comprising inter-head relay areas. Pixels in the pixel arrays are selected so as to realize N-overlay exposure ideally by causing overexposure and underexposure to be minimal in the inter-head relay areas.
