Abstract
Abstract A plurality of facsimile machines each having a LAN interface function are connected to a LAN. The memory unit of each of the facsimile machines is shared by all of the facsimile machines. Thus, if the memory unit of one of the facsimile machines is full, information may be stored in the memory unit of one of the remaining facsimile machines through the LAN. If the plotter fails, received image information may be transferred to any other facsimile machine having an operative plotter through the LAN to have the received image information recorded on recording paper.
