PROBLEM TO BE SOLVED: To enable plural users to more pleasantly use a device in common. SOLUTION: In the case the user selects one recording paper housing part from an operation part 1028, a CPU 1026 requires the user to input data for making the selected housing part usable. When the user inputs the data for making the housing part usable, the CPU 1026 compares the data with previously registered data for restricting the use thereof. In the case they coincide, the CPU 1026 permits the user to use the housing part, and actuates a recording paper feeding device control part 1029 to execute copying operation. In the case the user does not select the recording paper housing part or using the selected housing part is not permitted, the CPU 1026 permits to use parts other than a printer control part 1024 and the control part 1029. |
