CONSTITUTION: When a prescribed original document 2 is set on an original platen 1 and then, a confidential document copying button 5 is depressed, a call originating member 18 is stuck to the fixed position of the obtained copy document by a call originating member supplying part 12 and fixed to the copy document by a fixing part 15, to make a copy document with the call originating member 17 as the confidential copy document. When the copy document with the call originating member 17 which is made in this way is copied in a copying device, an electrical signal issued from the originating member 18 is detected by a call originating member detecting part 7.
