    • A photo receptor belt edge detection apparatus by which out-of-alignment of color images which arises from displacement of scanning start positions for different colors on a photo receptor belt of a color image formation apparatus can be eliminated with a simple construction to allow superposition of color images to be performed with a high degree of accuracy is disclosed. A plurality of beam detector signal generation elements output beam detector signals representative of starting of scanning when corresponding laser beams are received. After an arbitrary interval of time after the beam detector signals are received, light emitting diodes of each of belt edge detecting LED devices are successively energized to emit light in a main scanning direction. Belt edge detectors output detection signals till timings at which the light from the belt edge detecting LED devices is intercepted by an edge of a photo receptor belt. In response to the detection signals, video clock signals are outputted in synchronism with falling edges of the detection signals. Laser diodes serving as exposure light sources are energized to emit light in response to video signals synchronized with the video clock signals.

    • An image registration method and apparatus for an electrophotographic color imaging system in which a scanning laser beam is used to create a latent image on a photo receptor belt. The belt, which moves continually in a direction transverse to the beam scanning direction, is also subject to unwanted movement in the scan direction which may degrade the latent image. For each scan cycle, the time the scanned laser beam encounters a selected edge of the belt is recorded, and is used to create a synchronized clock signal for controlling the modulation of the laser beam by the image data. A scan control synchronizing signal is also generated at a predetermined time after the edge of the photo receptor belt is encountered by the beam, to activate modulation by the image data. This assures that each write cycle begins at the same location relative to the edge of the belt, without the need to reposition the belt.
    • 一种用于电子照相彩色成像系统的图像配准方法和装置,其中使用扫描激光束在光电接收器带上产生潜像。 沿垂直于光束扫描方向的方向连续移动的带也可能在扫描方向上受到不希望的移动,这可能使潜像降解。 对于每个扫描周期,记录扫描激光束遇到带的选定边缘的时间,并且用于创建用于通过图像数据控制激光束的调制的同步时钟信号。 在光束遇到光接收器带的边缘之后的预定时间也产生扫描控制同步信号,以激活图像数据的调制。 这确保了每个写入周期从相对于带边缘的相同位置开始,而不需要重新定位带。
