Abstract

PURPOSE: To shorten a time necessary for copying by executing reading in accordance with the conditions of a recorded part and a non-recorded part on a blackboard, and changing the speed of a record in an auxiliary scanning direction.
CONSTITUTION: A recorded line detection circuit 11 fetching a binary picture signal D which read and obtain picture block B, a line synchronizing signal C and a scanner, and deciding the presence and absence of a recorded picture on the blackboard bayed on the data; a buffer memory 12 fetching and storing the binary picture signal D; and a control unit 13 which is connected to the detection circuit 11, the memory 12, the driving means of the scanner and the recording paper carrying means of a copying device, which alters the content of the signals based on the decided result of the detection circuit 11 and which controls respective connected circuits are provided. If the recorded part does not exist on the optional line of the blackboard, it is detected and the shifting speed of the scanner and the speed of carrying the recording paper are fastened. Thus, the copying time can be shortened.
