Abstract

A telephone apparatus has abbreviated number input means for inputting an abbreviated number in a predetermined form, password input means for inputting a password in a predetermined form, a telephone number memory section for storing terminating subscribers' telephone numbers in correspondence with combinations of abbreviated numbers and passwords, and a control section for selecting and outputting a terminating subscriber's telephone number from the telephone number memory section in response to a dialing start signal and on the basis of a combination of an abbreviated number and a password included in the dialing start signal. Thus, since the telephone number memory section is accessed on the basis of a combination of an abbreviated number and a password, even if an abbreviated number is known, the corresponding terminating subscriber's telephone number is not read out unless an appropriate password is input. Accordingly, there is no fear of the stored telephone numbers coming to a third person's knowledge.
