PURPOSE:To finely control the restrictions of registering operation to individual operators. CONSTITUTION:Limitation information on the registering operation is stored on cards that the respective operators have corresponding to the operators. For example, when a discount key is operated to declare discount registration, the limitation information on the discount registration which is stored on the operator's card is recognized. Then, when the discount registration is permitted, the key input of the discount key is made effective, but when the registration is inhibited, the key input is made ineffective. |
