Abstract

PURPOSE:To display a calling party number sent from a calling party side, to display a telephone number of the other party side called by dialing, by the same number display device, by providing the number display device on a telephone set. CONSTITUTION:When a call signal is sent to a telephone set TEL through telephone lines L1, L2 from a calling party side, a neon lamp Ne-1 is lighted, a resistance value of CdS falls, circuits at and after IC-53 of C-MOS are operated and display of dial information is prepared. When the first bell stops ringing, the number information of the calling party comes in, therefore, it is inputted to an information receiving circuit following a line transformer LT, and the number is displayed on light emission diode indicators DT1-DT12 by outputs of decoders IC-33-IC- 44. In case of outgoing from this telephone set, contacts f1-1, f1-2 are switched by hook- off, circuits after IC-66 are operated, and a dial number is displayed on the light emission diode display devices.
