摘要： An scanning unit scanner includes a light source and a polygon mirror unit. A front-to-rear rib is disposed between the light source and the polygon mirror unit and near the polygon mirror unit. An input side opening having a slit shape is formed as a cutout in the top edge of the front-to-rear rib. When laser light from the light source passes through the input side opening, the input side opening restricts the width of the light in a main scanning direction.

摘要： The print permitting ratios of the masks in the first to fourth passes of a C ink are respectively 6.2%, 37.5%, 37.5%, and 18.8%. On the other hand, the print permitting ratios of the masks in the first to fourth passes of an M ink are respectively 12.5%, 37.5%, 37.5%, and 12.5%. In this way, the respective masks are set such that a larger amount of the C ink is applied in a later pass as compared with the M ink. Thereby, it is possible to reduce an amount of the M ink to be applied later with respect to the C ink functioning to “reduce a permeation speed of an ink applied later by filling,” and it is possible to prevent a permeation speed from slowing down overall. As a result, it is possible to prevent the occurrence of beading due to a time to complete permeation becoming longer.
摘要翻译： C油墨的第一至第四道次的掩模的印刷许可比分别为6.2％，37.5％，37.5％和18.8％。另一方面，M墨水的第一至第四遍中的掩模的印刷许可比率分别为12.5％，37.5％，37.5％和12.5％。以这种方式，各个掩模被设置为使得与M墨水相比，稍后通过更大量的C墨水被施加。由此，可以减少相对于“降低通过填充涂敷的油墨的渗透速度”起作用的C油墨稍后施加的M油墨的量，并且可以防止渗透速度变慢整体下降。结果，可以防止由于完成渗透的时间变长而发生珠粒。

摘要： A laser beam scanner converges a laser beam by using a first fθ lens and a second fθ lens in a main-scanning direction and in a sub-scanning direction, respectively, onto a photosensitive medium, thereby forming a scanning line on the photosensitive medium along the main-scanning direction. Before scanning the photosensitive medium, the laser beam that has passed through and been converged by the first fθ lens, but not passed through the second fθ lens, is guided to a beam detector and converged by a cylinder lens in the sub-scanning direction so that the laser beam falls within a detection area of the beam detector. The beam detector determines a scan start time by detecting the laser beam.

摘要： A multibeam scanner for scanning an image area with a plurality of laser beams, comprising a plurality of beam emitting points that emit a plurality of laser beams reaching the image area with respective time lags therebetween, a time lag determination unit that determines at least one of the time lags during a predetermined calculation time, a scan controller that controls the plurality of beam emitting points to emit the plurality of laser beams successively in the image area with the at least one of the time lags determined by the time lag determination unit. The multibeam scanner of the invention, comprises a photodetector that detects any one of the laser beams at a predetermined beam detection position. The time lag determination unit determines the time lag between the nth laser beam and the n+1th laser beam. Therefore, to scan the image area, the photodetector detects the first laser beam at the predetermined beam detection position, prior to the image area, and determines a scan start time for the first laser beam. Then, the scan controller starts controlling the first beam emitting point at the determined scan start time to emit the first laser beam in the image area. The scan controller further controls the n+1th beam emitting point to emit the nth laser beam in the image area with the calculated time lag between the nth laser beam and the n+1th laser beam.

摘要： A multibeam scanner capable of scanning an image forming area with constant beam amounts of laser beams. The multibeam scanner of the invention performs automatic power control (APC) on each of a plurality of beam emitting points one by one during corresponding time durations, respectively, in a non-image forming area. The laser beam emitted last among the plurality of laser beams is controlled to reach a predetermined beam detecting position within the corresponding time duration. Before scanning the image forming area, the multibeam scanner determines a scan start timing upon the detection of the laser beam emitted at the beam detecting position, which has been stabilized during APC. This arrangement allows the laser diode to avoid wasting time again and again, as rise time for stabilizing the laser beam for performing APC and for identifying the scan start timing, and to secure the time durations as long as possible. It is therefore possible to perform APC against the laser diodes properly during the sufficient time durations and, at the same time, possible to determine the scan start timing precisely by detecting the stabilized laser beam.
摘要翻译：一种能够以恒定光束量的激光束扫描图像形成区域的多光束扫描仪。本发明的多光束扫描器分别在非图像形成区域中的相应时间期间逐个地在多个光束发射点的每一个上执行自动功率控制（APC）。控制在多个激光束中最后发射的激光束在相应的持续时间内到达预定的光束检测位置。在扫描图像形成区域之前，多光束扫描器在检测到在APC期间已经稳定的光束检测位置处发射的激光束时确定扫描开始时刻。这种布置允许激光二极管避免一次又一次地浪费时间，作为用于稳定用于执行APC的激光束和用于识别扫描开始定时的上升时间，并且尽可能长地确保持续时间。因此，可以在足够的持续时间内适当地对激光二极管执行APC，并且同时可以通过检测稳定的激光束来精确地确定扫描开始定时。
