PURPOSE:To allow an off-line sorter to perform secure interruption processing, by inhibiting the drive of a sorter pin and counting operation while inhibiting printing operation for a certain time when an interruption signal is received. CONSTITUTION:When an interruption signal S19 is received, an OR circuit O outputs a printing disabling signal S6 for inhibiting the printing operation of a copying machine body for a certain time. At the same time, the counting operation of a counter CNT and pin driving operation are inhibited for a certain time. As a result, copying during interruption and normal copying are discriminated clearly and after interruption operation, sorter operation is continued again at an interruption point. Thus, secure interruption processing is carried out. |
