Abstract

PURPOSE:To reduce the transmission time, by inputting the information relating to the width of an original to a control section. CONSTITUTION:When an original 18 is inserted into a housing 24, a sensor 20 detects the insertion of the original 18 and supplies the signal ''1'' to a latch 25. A control circuit monitors the output of the latch 25 to be ''1'' and after the output of the latch 25 is at ''1'', the output of latches 26-28 is checked and the size of the original is discriminated. A control circuit 29 changes the period of phase signal in response to the size of the original to assign the main scanning time of one line proportional to the main scanning line length equal to the size of width of the original.
