Claims (1)

[Scope of utility model registration request] A plurality of light emitting display elements, a bell incoming call detection circuit,
A counting and storage circuit that counts the number of incoming bell calls based on the output of the bell incoming detection circuit and stores the counted value; a timing signal generation circuit that generates a timing signal for blinking the plurality of light emitting display elements; and a reset circuit that resets the counting and storage circuit after a predetermined period of time has elapsed from the off-hook point detected by the monitoring circuit, and the output of the timing signal generation circuit and the output of the counting and storage circuit are connected to each other. An incoming call number display device that displays the number of incoming calls by blinking the plurality of light emitting display elements based on the above.
