Abstract

A copying machine that allows copying by inputting an access code at the time of use without registering said access code in advance and that can also register said access code. In the control routine by CPU 601 that controls the copying machine, when a control-by-section mode selection signal is input using key 45 on the operation panel, selection of automatic code input mode (the second mode), which is different from regular mode (the first mode), is permitted. When automatic code input mode is selected and an access code is input using 10-key keypad 42 on the operation panel, the input access code is registered and control is performed so that the copying operation is permitted. By limiting the period of validity for the access codes registered, the memory capacity in the access code registration memory may be effectively utilized and only sections that actually use the copying machine can be registered.
