ABSTRACT:
A calling party's telephone number displaying device in which, while the telephone set of a subscriber is ringing in response to calling signals from a telephone exchange office, the telephone number of a calling party and information are displayed on digital display units at high speed before lifting the handset. Accordingly, the subscriber can determine whether or not he should answer the call before picking up the handset. Thus, his privacy can be protected from a variety of telephone troubles such as wrong number and nuisance calls. The display is maintained as it is even if the handset is put back after the talk but it will be cleared automatically upon reception of the next call to display the telephone number of the next calling party. When the subscriber picks up the handset to make a call, the internal circuit is automatically changed to display a telephone number dialed by him.
