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.
摘要翻译：激光束扫描仪通过在主扫描方向和副扫描方向上将第一透镜和第二透镜分别在激光束上会聚到感光介质上，从而在感光介质上形成扫描线主扫描方向。在扫描感光介质之前，已经通过并被第一晶片透镜会聚但不通过第二透镜的激光束被引导到光束检测器并且被副透镜在副扫描方向上会聚，所以激光束落在光束检测器的检测区域内。光束检测器通过检测激光束来确定扫描开始时间。

摘要： In an image forming apparatus, a polygon mirror, a plurality of laser generators, a first sensor, and a second sensor are disposed at a frame formed with a resin. A laser beam outputted from the laser generator and deflected by a deflection surface is irradiated onto a photosensitive surface of a photosensitive drum to scan the photosensitive surface over a scan part. The first sensor is disposed at a first position to detect a laser beam deflected by the deflection surface. The second sensor is disposed at a second position to detect a laser beam deflected by the deflection surface. A storage unit stores correspondence information indicating shift of the scan part from a reference scan part in relation to time difference between detections of the laser beam by the first sensor and the laser beam by the second sensor. The correspondence information varies with temperature variation in the frame. A controller controls the laser generator to output a laser beam based on the shift of the scan part.
