摘要： An optical writing apparatus whereby non-light-emitting portions that might exist between adjacent light-emitting elements arranged in parallel rows can be substantially eliminated either in the direction of the rows or in the direction perpendicular to the row direction. In addition, dotted latent electrostatic images can be formed in such a way that adjacent dots partially overlap with each other, thus contributing to improved image quality and resolution. Further, because light-emitting elements are connected to a common anode electrode, a reduced number of electronic devices is required to drive the elements.

摘要： An optical write head for an electrostatic dot-matrix image printing system which includes a plurality of controlled light emission element row-arrays positioned parallel and spaced in the direction perpendicular to the row-wise direction a distance equal to an integer multiple of the desired dot image-pitch S measured in the perpendicular direction, corrected by the fraction S/N where N is the number of row-arrays. A timed electrode drive circuit activates the arrays sequentially, and grid mask elements extending transversely across the row-arrays control emission from the individual light emission elements in an activated array, to minimize the number of drive circuit switching elements. A series-to-parallel signal conversion and storage circuit preprocesses the recording signal of the image to be printed.
