PURPOSE:To perform simultaneous operation for input and output and to shorten an operation time by providing an input scanner control part and an output scanner control part, and inputting a scan start position and a scan range to an arithmetic part previously through a keyboard. CONSTITUTION:The subscan start position PS1 and range PR1 of an input head 5 and the subscan position PS2 and range PR2 of an output head 8 are stored in a memory 13 through the keyboard 17. Then, input data D1 is inputted to the input scanner control part 15 and inputted to the arithmetic part 12 as input data DD1 of every drum turn. Further, the arithmetic part 12 outputs output data DD2 to the output scanner control part 16 as output data D2. Thus, data to be output is already stored in the memory 13 and input data from the head 5 is stored in the memory 13 when a scan begins to be made; and the output data of the memory 13 is inputted to a head 8 and input and output operation is performed simultaneously. |
