PURPOSE:To enable many receivers to receive continuously the same signal at one time via a telephone circuit and to receive selectively the transmitting signal, by adding a receiver capable of a switching connection to a telephone set and then dialing a specified telephone number through the telephone. CONSTITUTION:An FAX signal producer contains a signal converting part 8, a CPU part 9, a data input part 11, etc. The signal is transmitted by the FAX signal producer to a trunk line interface part 6 via an FAX interface part 7. When this signal is received, specified telephone number is dialed through a telephone 2 connected to an FAX receiver 1 and connected to either one of trunk lines 5 connected to the part 6 via a subscriber line 3 and a switchboard 4. In this case, the receiver 1 can be connected to the telephone 2. Thus a signal or superposed FAX signal is received continuously by the receiver 1 from the FAX signal producer and FAX transmitter 14 via the part 7. |
