PROBLEM TO BE SOLVED: To make the manufacture of an imitation hard and to eliminate the circulation of a specious part by stopping operation or recording a status where the specious part is used, when it is used and recognizing the working condition of the specious part. SOLUTION: A control part 7 transmits a read-out command with a signal processing circuit in a data reading unit, to read the data of the data carrier 3 of an attached ink bottle. An ink bottle 2 corresponding to a specific type of copying machine is attached thereto. It is discriminated whether correct data corresponding to this specific type of copying machine is written or not by the data carrier 3. When normal data is received, a copying operation is executed. When the correct data is not obtained from the data carrier 3, it is judged that the ink bottle 2 which is not of a genuine part is attached, so that a warning that the ink bottle 2 is of the specious one is displayed on a display panel 4. At this time, information on an attempt to be copied by using the specious bottle 2 is written in a memory 8, without being copied. |
