摘要： In a system for irradiating a recording medium with combined laser light which is generated by combining laser beams emitted from laser-light sources: a fraction of the laser-light sources are selected when a target value of the optical output power of the combined laser light determined in correspondence with the photosensitivity of the recording medium is smaller than a predetermined reference value. Then, each laser-light source in the fraction of the laser-light sources is driven with a driving current within a range from the oscillation threshold current to the maximum rated current of each laser-light source, and the remaining fraction of the laser-light sources which are not selected above are stopped, so that the optical output power of the combined laser light is equalized with the target value.

摘要： A light quantity adjusting method is used for driving a light emitting device with two drive current levels. The drive current levels are controlled by the first set data and the second set data, respectively. First, a resolution ratio and light quantity characteristics are stored. The resolution ratio represents a ratio between a drive current setting resolution of the first set data and a drive current setting resolution of the second set data. The light quantity characteristics represents a relationship between the first set data and a light emission quantity of the light emitting device. A value in the first set data is obtained as a first set value through adjustment for a quantity of light. Next, a change amount, from the first set value in the first set data is calculated using the light quantity characteristics. The calculated change amount is converted into a value in the second set data as a second set value using the resolution ratio.

摘要： A recording material is angled and wound on a rotating drum. Distortion (inclination) of an image can be eliminated with a comparatively simple control system, and the occurrence of distortion when there is a change in image recording specifications can be prevented. For standard specifications, although image recording lines have helical movement tracks during image-recording, a peripheral end of a printing plate and a peripheral end of an image region can be made to be parallel with one another without distortion of the image region. In contrast, when instructed specifications differ from the standard specifications, a conventional image region becomes distorted because an inclination angle of the printing plate cannot be varied. Accordingly, in a case in which instructed specifications differ from the standard specifications thus, image data is shifted in a sub-scanning direction by soft processing, and the distortion is alleviated.
摘要翻译：记录材料成角度并缠绕在旋转的滚筒上。可以通过相对简单的控制系统消除图像的变形（倾斜），并且可以防止在图像记录规格的变化时发生失真。对于标准规格，虽然图像记录线在图像记录期间具有螺旋运动轨迹，但是可以使印版的外围端和图像区域的外围端部彼此平行，而不会使图像区域失真。相反，当指示的规格与标准规格不同时，由于印版的倾斜角度不能改变，传统的图像区域变形。因此，在指示规格与标准规格不同的情况下，图像数据通过软处理沿副扫描方向移位，并且减轻失真。

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.
