However, at this time, if the wireless connection with the facsimile device of the cordless slave device is not normally established, the master device performs the facsimile communication by the facsimile modem provided in the master device, and the image information sent from the sender is stored in the memory. Controlled to store. Therefore, even if the cordless cordless handset facsimile device is in a place where the radio wave from the parent device does not reach, or the radio wave condition is poor and the cordless cordless handset facsimile device cannot be wirelessly connected, the facsimile reception can be performed. . If the wireless connection with the cordless cordless handset facsimile device is normally established at the start of the facsimile reception, the cordless cordless handset facsimile device performs a normal facsimile receiving operation. At this time as well, the parent machine performs the receiving operation by the facsimile modem and stores the image information sent from the facsimile sender in the memory. That is, in this state, the receiving operation by the cordless facsimile machine and the receiving operation by the master machine to the memory are simultaneously performed in parallel. When the reception of the image information is completed, the receiving side transmits a signal indicating whether or not the image information is normally received to the facsimile transmission source. By monitoring the facsimile signal that the cordless cordless facsimile machine sends to the facsimile transmission source,
It is possible to know whether or not the facsimile reception in the cordless cordless handset facsimile device has been completed normally.
If it is detected that the facsimile reception by the cordless cordless handset facsimile device has ended normally,
The image information stored in the memory is erased, but when the normal termination is not detected, the image information stored in the memory is retained. Therefore, during facsimile communication, even if facsimile reception in the cordless cordless handset facsimile device could not be completed normally due to deterioration of the radio wave condition between the cordless cordless handset facsimile device and the cordless handset facsimile device, the image is stored in the memory of the parent device. Information is retained.

In any of the above cases, that is, when the wireless connection between the master and the cordless slave facsimile machine cannot be established at the start of the facsimile reception, and during the facsimile communication, the wireless communication between the master and the cordless slave facsimile machine is performed. Even when the condition deteriorates and normal communication cannot be performed, the facsimile device is controlled so that the facsimile modem provided in the master unit performs the facsimile reception operation and stores the image information sent from the facsimile transmission source in the memory. Therefore, the facsimile can be received regardless of the state of wireless connection between the master and the cordless slave facsimile machine.
