Abstract

PURPOSE:To obtain a telephone transmission recorder which can perform detection, display and recording for the dialed telephone number via the signal pickup and with no direct connection to the telephone circuit and also can record the talking time. CONSTITUTION:With setting of the telephone onto base board 1, the power is supplied to amplifier 13 and 14 via switch 3 and 4. When the handset is picked up, head 11 within signal pickup 6 detects the dial tone and actuates other circuits with pilot lamp 7 lit up. The dial pulse is detected by head 12 and then applied to counter circuit 17 and digit number command circuit 19 via mixer amplifier 15 to be displayed at display part 18(9). When the ringing tone stops and the talking is started, the signals given from head 11 drive relay 16. As a result, the dial number is recorded on recorder 20, and at the same time the output of timer 21 is recorded on recorder 20 every fixed time. The end of talking is detected at circuit 22.
