Abstract

PURPOSE:To secure an easy application to the automatic answering telephone set, by omitting the connection to the telephone circuit and also securing the recording of the calling time and ringing frequency through a simple constitution. CONSTITUTION:The ring signal TP detected through telephone pickup TPU such as the microphone or the like which has the property to detect the telphone ring tone at the calling time receives the waveform shaping by ring output circuit TCC to produce ring detection signal TC with every ringing to apply the signal to central arithmetic processor CPC. Processor CPC incorporates the arithmetic circuit which performs various types of calculations in response to operation of keyboard KB, the counter which counts the producing frequency of signal TC sent from circuit TCC plus the watch circuit. Thus the ringing frequency of signal TC and its calling time are measured to be printed on printing paper PP via printer PR. At the same time, switch SW is connected to processor CPC to secure the switching between the calculation mode to calculate the numerical value of keyboard KB and talking mode TEL. Thus the recording device can be used as a calculator when not in use as an automatic answering telephone set.
