[0002]

2. Description of the Related Art Conventionally, facsimile apparatuses having a relay broadcast function have been widely used. Image data is received from a facsimile apparatus as a request source, temporarily stored in a memory, and then received. The transmission is performed to a plurality of facsimile machines as transmission destinations.

[0003] With this, even when the requester and the plurality of destinations are far apart, the facsimile device installed near the destination receives the image data once as a repeater and transmits a plurality of facsimile transmissions. Doing so has greatly reduced communication costs. Further, a facsimile apparatus of this type having a non-delivery reply communication function has become widespread, and as one of the relay result reports, when there is a facsimile apparatus that could not transmit image data, the information is transmitted. Reply to the requesting facsimile machine.

However, in the above-mentioned conventional facsimile apparatus with a non-delivery reply function, the non-delivery reply function is used unless the sender's telephone number is registered in advance by a key operation or the like at the requester. could not. Also, if the requester does not correctly register the source telephone number, an incorrect transmission terminal identification signal (TSI signal) will be generated during the handshake in the facsimile communication procedure.
It is sent to the facsimile machine with the non-delivery reply notification function, which is a repeater. If there is a destination that could not perform facsimile transmission with this repeater, a telephone number other than the requester is called, Not only could not be notified of the non-delivery information, but also troubled the called party.

The present invention has been made in view of the above circumstances, and it is possible to return non-delivery information even if the caller's telephone number is not registered in advance at the requester, and the requester can accurately return the non-delivery information. It is an object of the present invention to provide a facsimile apparatus having a non-delivery reply notification function that can reliably return non-delivery information even when a source telephone number is not registered.

Further, when the caller's telephone number is not transmitted together with the call signal, the telephone number detecting / storing means for detecting and storing the caller's telephone number transmitted in accordance with the facsimile communication procedure is provided. If the original image cannot be facsimile-transmitted to the destination, the caller telephone number stored in the detection / storage means is automatically called and transmitted to the total number of pages of the facsimile-transmitted original image. Non-delivery information including unsendable page information to which a failed page number is added and a reduced image of a document image that could not be transmitted is returned to the facsimile machine that is the request source.

[0007] Here, the caller telephone number transmitted together with the call signal from the requester is included in the signal transmitted during the transmission of the call signal and during the call suspension period, and this signal is referred to in the United States as " Caller ID "and in the UK it is used in a system named" Caller Display ". In these systems, the telephone exchange exchanges information such as telephone numbers and time as a source information service.
It is included in a 200 bps modem signal and is added and transmitted during an intermittent call signal (for example, 2 seconds call, 4 seconds stop). The source telephone number detection / storage means for detecting and storing the source telephone number includes a communication modem, a dedicated IC, and the like, and a RAM, an EEPROM, and the like.

On the other hand, the transmission source telephone number transmitted according to the facsimile communication procedure is a transmission terminal identification signal (TSI signal) transmitted from the request source at the time of handshake.
Is used. In the facsimile apparatus of the present invention, when a call signal is received, the source telephone number detecting / storing means detects and stores the source telephone number transmitted together with the call signal. The facsimile apparatus receives image data from the requesting facsimile apparatus and operates as a repeater to sequentially transmit the image data to a plurality of requested destinations. When the transmission of the image data to all the transmission destinations is completed, the relay result is returned to the request source, but this facsimile device cannot be transmitted, or the transmission destination facsimile device cannot be received due to a call or the like, If the image data cannot be transmitted normally, the source telephone number of the request source stored in the source telephone number detecting / storing means is read out, automatically called, and non-delivery information is transmitted.

When the caller does not send the caller's telephone number together with the caller signal, the caller's telephone number (TSI) transmitted in accordance with the facsimile communication procedure.
