摘要： Optical fibers are used to sense fluid ink drops along the x, y and z axis of an orthogonal coordinate system. A drop sensing zone is defined in the narrow space between the faces of a single input fiber and two output fibers. An LED infrared light source is coupled to a remote end of the input fiber. Infrared sensitive photodiodes are coupled to the remote ends of each output fiber. The photodiodes are in turn coupled to a differential amplifier whose output represents a displacement error for the x and y axis and represents a time reference for the z axis for the case where the drop flight path is along the z axis. A plurality of sensors are disclosed in an ink recording system having a plurality of nozzles and in an ink recording system having an ink generator traversing the length of a high speed rotating drum.

摘要： A line scanning apparatus employing a multiplicity of linear arrays, the linear extent of which is less than the length of the scan line. To permit an entire line to be covered, the arrays are offset from one another in the direction of scan with adjoining array ends overlapped. To correct for the misalignment and redundancy introduced, the image data from the arrays is buffered until a line is completed when readout, is initiated. During readout, cross over from one array to the next is effected within the overlapped areas and the redundant data discarded.
