Abstract

PURPOSE:To obtain an information transmission device which is efective for transmission of the information at the transmission point and also highly effective when used for the general household purpose. CONSTITUTION:The input part 1 of the transmission device receives one or more than one unit of the input signal, and the control part controls the subsequent operations based on the input signals given from the input part to be then connected to the subscriber telephone circuit. The transmission destination memory part receives the transmission command from the comtrol part and generates the predetermined outgoing pulse to the circuit. With this signal the transmission circuit is prepared. The message memory reproducing part memorizes and reproduces the transmission message prepared at the transmission point, and one message is selected and reproduced by the signals sent from the control part to be sent to the circuit. Then the transmission circuit leads the signals transmitted up to the reception device. The circuit connection part of the reception device controls the circuit connection based on the reception signals, and the message memory part memorizes the received message along with the voice memorized directly. The miscellaneous circuit part comprises the time input circuit to memorize the reception time, the received message monitor circuit and others to be installed as an auxiliary parts.
