PURPOSE:To print out a telephone number of a party to be called, and a telephone number of a calling party, by use of a different color, by shifting a ribbon color of a printer in accordance with whether a transmitter and receiver is taken up or not. CONSTITUTION:When a call signal comes by incoming from a third party, it is detected by neon NE, a photodetecting body CdS, and a detecting circuit 1, display of a multi-digit indicator 10 is cleared by an output pulse from a pulse generating circuit 3, and simultaneously a printer 11 is line-fed and is made a holding state. After the call signal, since telephone number information of a calling party comes in at a medium or low speed from a station, it is inputted to the indicator 10 and an input terminal DI of the printer 11 through a waveform shaping circuit and a data receiving circuit 5, etc., and is displayed and printed in black. When transmitting, hook switches HS1-HS3 are changed over, a circuit operation of circuits IC-82- IC-93 is executed by detecting a dial tone, a ribbon shifter RS of the printer 11 is driven, is changed over to a red ribbon, a telephone number of a party to be called detects a dial and is printed in red. |
