Abstract
The invention provides an image duplicating apparatus capable of performing duplicating operations with its whole operation time shortened by the simple speed adjustments, without increasing the size of the memory as much as possible and its costs. When images are duplicated, for example, at full scale, a CPU starts executing the input/output processing of the image line data. The image line data is written into a line buffer memory and at least one line of the image line data written in the line buffer memory is retained. Upon the receipt of the data output request from the printing unit, the CPU reads out the image line data retained in the line buffer memory and outputs it to the printing unit. The CPU repeatedly performs the above-described steps. The duplicating operations may be performed with the space for storing at least two lines of the image line data secured in the line buffer memory.
