Abstract

PROBLEM TO BE SOLVED: To send out non-delivery information by automatically calling a call originating source telephone number when facsimile transmission to the transmission destination can not be performed by detecting and storing the call originating source telephone number to be sent out together with a call signal. SOLUTION: When a call signal detection circuit 1e detects the call signal, facsimile equipment F passes the modem signal of 120bps by an AC coupling part 1c, demodulates, detects and decodes it by a communication modem 1a. A signal processing part 4 extracts the call originating source telephone number contained in the demodulated signal by the call originating source information service of a telephone exchange station and stores it in the call originating source memory of a RAM 5b. Afterwards, image data provided by performing facsimile reception are stored in the image memory of the RAM 5b and further, those image data are successively transmitted to the plural transmission destinations requested as repeaters. When the facsimile transmission to the desired transmission destination can not be performed, the non-delivery information is sent out by reading the call originating source telephone number out of the call origination memory of the RAM 5b.
