PURPOSE:To prevent an apparatus from being operated easily by other person, by executing a prescribed operation by a password number and an individual number which have been held in a device, comparing and collating its result and the inputted contents and controlling an operation of the apparatus. CONSTITUTION:A password number A which has been inputted from a data input part 1 is inputted to a comparing and collating part 3. Also, a password number B' which has been held in a password number holding part 2, and an individual number which has been held in an individual number holding part 5 are inputted to an operation input part 3 and prescribed operation is executed. A result of the operation is inputted to the comparing and collating part 3, and compared and collated with the password number A. As a result, when both of them coincide, a control is executed so that an apparatus starts normally an operation through an apparatus control part 6. Also, when the password number A is not inputted, or both of them are not equal as a result of the collation, an operation stop state of the apparatus is held. Accordingly, unless not only the password number and the individual number but also the operating method are known, an operation of the apparatus becomes impossible. |
