PURPOSE:To stop adequately each of image processors which are independently usable in the event of abnormality by connecting plural image processors and providing control means which disable all the processors when imperfect connection is detected to each of the units. CONSTITUTION:The connecting condition of a male type connecting part (projecting part) 1 of an image processor (for example, copying device) engaged and connected to the inside of a female type connecting part (recessed part) 2 of the other processor having the similar constitution is investigated with detecting sensors 3, 4 consisting of a pair of push-switches. Whether the swithes 3 and 4 are both on or not is supervised in a sub-routine for diagnosing the connection and copying and whether the mechanical connection is perfect or not is judged. If the connection is imperfect, a copying prohibition signal C11 is transmitted and the processing to stop copying and to display the abnormality in connection is performed, whereafter the monitoring of a detection signal C4 for connection is continued until the connection is made perfect. All of the copying including the copying device in which the abnormality arises and in the stages before said device are stopped in the event of abnormality. |
